Field experiment was carried out at Shamnagar, Satkhira Sadar for the improvement of wheat production in saline areas through irrigation application and gypsum amendments. Two wheat cultivars viz. L-880-43 and BARIghom- 26 were used as test crops. There were six treatments such as control (no irrigation); one irrigation at vegetative stage with canal water (canal water means rainwater harvested in natural/man-made canal); one irrigation at vegetative stage with STW water + Gypsum application @ 200 Kg/ha (STW means sallow tube-well); Irrigation at vegetative and heading/flowering stage with canal water; Irrigation at vegetative stage with saline canal water + Gypsum application @ 200 Kg/ha; Irrigation at vegetative and heading/flowering stage with STW water + Gypsum application @ 200 Kg/ha. The treatments were allocated in the main-plot and the cultivars in the sub-plot all experimental plots received recommended doses of urea, triple super phosphate, and muriate of potash. The treatments were imposed accordingly. The results showed that soil salinity caused a significant reduction in growth and yield components of both wheat cultivars. Irrigation application and Gypsum amendments significantly increased the growth and yield components of both cultivars under soil salinity. Soil salinity also reduced grain yields of both cultivars. Combined application of irrigation water and gypsum amendments showed higher yields than that of sole application of irrigation water during saline conditions. Gypsum used as amendments because it reduces the soil salinity. Therefore, the present study suggests that wheat production might be feasible in coastal areas of southern Bangladesh (saline soils) through irrigation application and gypsum amendments.</p> <p>Res.

Accumulation of organic compound is one of the adaptive mechanisms to salinity in plants. The experiments were laid out in a randomized complete block design with three replications at the farmer’s field of Botiaghata, Khulna to investigate the mitigating effects of organic manures on salinity stress in rice genotypes during both aman and boro seasons. Two T. aman rice (salt-sensitive; BR-23 and local cultivar; Mohini) and two boro rice (salt-sensitive; BRRI dhan-29 and salt-tolerant; BINA dhan-8) were used as test crops. Farmyard manure (FYM) and poultry manure (PM) were applied to the soils during final land preparation. There were five treatments namely T<sub>0</sub>= control (no manure), T<sub>1</sub>=FYM (5 t/ha), T<sub>2</sub>=FYM (10 t/ha), T<sub>3</sub>=PM (4 t/ha), T<sub>4</sub>=PM (8 t/ha).Thirtyday- old rice seedlings were transplanted in the experimental plots. Salinity caused a significant reduction in growth and yield of both aman and boro rice. Under saline condition, BR-23 (aman rice) produced higher yield than local cultivar Mohini in aman season while BINA dhan-8 produced higher yield than BRRI dhan29 in boro season. Soil amendments with FYM and PM significantly increased the growth, and grain and straw yields of all rice cultivars under saline conditions. Increased nutrient uptake and K<sup>+</sup>/Na<sup>+</sup> ratio in rice were also observed due to application of organic manures. No considerable changes in post-harvest soil properties such as pH, EC, CEC and organic matter status of saline soils were observed by addition of FYM and PM. The present study suggests that soil amendments with FYM and PM improve salt tolerance in rice by increasing K<sup>+</sup>/Na<sup>+</sup> ratio and nutrient uptake.</p> <p>Res. Agric., Livest.

BARI piaz-1) 2019-05-14T09:10:40+00:00 Nazmul Islam Mazumder Tania Sultana Prtitish Chandra Paul Md Mahmud Al Noor <p>The productivity of onion crop is poor due to inappropriate management and agronomic practices in Bangladesh. To figure out the effect of NPK fertilizer rate and spacing on growth parameters of onion a field experiment was conducted. The treatments were consisting of N fertilizer (0, 80,120 and 160 kg/ha), P fertilizer (0, 30, 50 and 70 kg/ha), k fertilizer (0, 50, 75 and 100 kg/ha) and three plant spacing viz., 10 cm × 10 cm, 15 cm × 10 cm and 20 cm × 10 cm. The experiment was designed in RCBD with three replications. Analysis of results indicates that the interaction effect of NPK rate and spacing shows significant (P&lt;0.05) effect on plant height. Highest plant height was obtained in 20 cm × 10 cm spacing and application of 160 kg N/ha, 70 kg P/ha and 100 kg K/ha respectively. Moreover, maximum number of leaves was also found by plants spaced at 10cm and application of highest dose of fertilizers. Lowest plant height and number of leaves was attained in 10 cm × 10 cm spacing and without NPK fertilizer application. The total result analysis reveals that best growth performance of onion was found from 20 cm × 10 cm spacing combined with 160 kg N/ha, 70 kg P/ha and 100 kg K/ha fertilizer amendment.</p> <p>Res.

The soil was silt loam in texture having pH 6.27, organic matter content 1.95% and total N 0.136%. The experiment was laid out in a Randomized Complete Block Design (RCBD) with eight treatments and three replications. The treatments include T<sub>1</sub> (Control), T<sub>2</sub> (PU, 104 kg N ha<sup>-1</sup>), T<sub>3</sub> (USG, 104 kg N ha- 1), T<sub>4</sub> (USG 78 kg N ha<sup>-1</sup>), T<sub>5</sub> (USG, 52 kg N ha<sup>-1</sup>), T<sub>6</sub> (NPK briquettes, 104 kg N ha<sup>-1</sup>), T<sub>7</sub> (NPK briquettes, 78 kg N ha-1) and T<sub>8</sub> (NPK briquettes, 52 kg N ha<sup>-1</sup>). All the treatments except <sub>T</sub><sub>6</sub><sub>,</sub> T7 and T<sub>8</sub> received 16 kg P and 42 kg K ha<sup>-1</sup> from TSP and MoP, respectively. In T<sub>6</sub>, T<sub>7</sub> and T<sub>8</sub> treatments, P and K were supplied from NPK briquettes. The PU was applied in three equal splits. The USG and NPK briquettes were deep placed 10 DAT and the briquettes were placed at 8-10 cm depth between four hills at alternate rows. Application of PU, USG and NPK briquette under alternate wetting and drying (AWD) condition exerted significant influence on yield attributes as well as grain and straw yields of BRRI dhan49. The maximum grain yield of 6311 kg ha<sup>-1</sup> (100% increases over control) and straw yield of 6956 kg ha<sup>-1</sup> was recorded in T<sub>3</sub> (USG, 104 kg N ha<sup>-1</sup>). The second highest grain yield of 5865 kg ha-1 produced by T<sub>2</sub> (PU, 104 kg N ha<sup>-1</sup>) was statistically similar with T<sub>4</sub> (USG 78 kg N ha<sup>-1</sup>) and T<sub>6</sub> (NPK briquettes, 104 kg N ha<sup>-1</sup>). The lowest grain yield (3155 kg ha<sup>-1</sup>) and straw yield (3908 kg ha<sup>-1</sup>) were recorded in T<sub>1</sub> (Control). The deep placement of USG and NPK briquettes enhanced both the recovery of applied N and N use efficiency in comparison with broadcast application of prilled urea. The T<sub>5</sub> (USG, 52 kg N ha<sup>-1</sup>) showed maximum apparent N recovery, and N use efficiency. Next to T<sub>5</sub>, the T<sub>4</sub> depicted the position in respect of N recovery and N use efficiency. So the application of 78 kg N ha<sup>-1</sup> in the form of USG can be recommended for the production of BRRI dhan49.</p> <p>Res. Agric., Livest.

Data were collected from 72 mango orchards using random sampling method. Descriptive statistics, profitability analysis and Cobb-Douglas type production function was used to analyze data. The per hectare gross cost, gross return and net return were Tk. 507817,Tk. 72,8419 and Tk. 22,0602 respectively for the 6-7 years of Khirshapati mango orchard. Net present value was Tk. 65,343 and benefit cost ratio was 1.16 which ensures that investment in mango cultivation is financially feasible. Mango cultivation was also found to be a profitable enterprise since internal rate of return was 20%.The functional analysis indicates that per hectare yield were significantly positively influenced by age of the orchard, number of tress and amount of fertilizer. The results also show that area and amount of manure had significant negative effects. So a proper initiative should be taken to disseminate this information among the mango growers to sustain the yield of Khirshapati mango in Bangladesh.</p> <p>Res. Agric., Livest.

The experiment was laid out in a split plot design with three replications where factor (A) irrigation stages were allocated in main plots and factor (B) varieties were distributed in sub plots. In factor A five irrigation management viz. I<sub>0</sub> = (No irrigation), I<sub>1</sub>= (Four leaf stage + eight leaf stage + tasselling stage+ grain filling stage), I<sub>2</sub>= (Four leaf stage+ eight leaf stage + tasselling stage), I<sub>3</sub>= (Eight leaf stage + tasselling stage +grain filling stage), I<sub>4</sub>=(Four leaf stage + tasselling stage+ grain filling stage), I<sub>5</sub>=(Four leaf stage+ eight leaf stage+ grain filling stage) and in factor B three varieties viz. V<sub>1</sub>= (BARI hybrid vutta-9), V<sub>2</sub>= (BARI hybrid vutta-13), V<sub>3</sub>= (pacific-559) were included as treatments in the experiment. Data were collected on yield and yield contributing characters. The highest grain yield (5.88 t/ha) was obtained with the water management treatment I<sub>1</sub>(Four leaf stage + eight leaf stage + tasselling stage+ grain filling stage) which is statistically similar to treatment I<sub>4</sub>(Four leaf stage + tasselling stage+ grain filling stage) and highest grain yield (5.87 t/ha) obtained due to the varietal factor V<sub>3</sub> (pacific-559). Interaction between I<sub>1</sub> irrigation treatment and V<sub>3</sub> varietal factor (I<sub>1</sub>V<sub>3</sub>) were found to be the best combination which is statistically similar to I<sub>4</sub>V<sub>3</sub> interaction. As I<sub>4</sub> treatment and I<sub>4</sub>V<sub>3</sub> interaction are cost effective than I<sub>1</sub> treatment and I<sub>1</sub>V<sub>3</sub> interaction, respectively, irrigation should be given at four leaf stage, tasselling stage, and grain filling stage with variety pacific-559 for better performance in maize production.</p> <p>Res.

Recently, vegetable production on the Dykes is gaining popularity in the southwest coastal region. The main purpose of the study was to identify the present status of Dyke Vegetable Production (DVP) in gher and to determine the problem confrontation associated with DVP. Data were collected from randomly selected 84 respondents (50% out of 168 gher owners) of five selected villages of Mollarhat upazila under Bagerhat district, through face-to-face interview using a pre-tested interview schedule during February to April, 2018. Collected data were analyzed by using SPSS software for different statistical techniques and for obtaining results and subsequent interpretation for satisfying the mentioned purpose of the study.Most (86.9%) of the respondents had medium to large sized Dykes, and thus the respondents could bring their Dyke area under vegetables cultivation instead of keeping fallow year after year. The gher owners harvested on an average 218.47 kg vegetable and earned 3,383.807 Tk. annually from one decimal Dyke area which is an additional income. The gher owners who have large sized Dyke in ghers continued production due to high quantity of cumulative profit. About half (51.19%) of the respondents grown lady’s finger in the Dykes during lean period followed by brinjal (48.81%) and tomato (47.61%). The respondents produced 53,962.09 kg ha<sup>-1</sup> which is completely extra production contributing to food security. A number of 29 problems were identified as confronted by Dyke vegetables growers with different extent of severity. The most severe problem in Dyke vegetable farming in the study area was “lack of technical knowledge for identification of diseases”. Most of the respondents (96.4%) belonged to medium problem confrontation category. Among 13 selected characteristics of the respondents only annual family income showed a significant positive relationship and extension contact showed a negative significant relationship with the problem confrontation. The gher owners confront medium problems and appropriate measures should be undertaken to reduce these problems as minimum as possible.</p> <p>Res. Agric., Livest.

The study encompasses the comparison of cost and profit of other crop with mango cultivation. Most farmers depend on mango production because the climate is unfavorable for field crop production but very conducive for mango cultivation in Barind ecosystem. Problem Confrontation Index (PCI) was used to measure the problems of mango production. On the basis of PCI formula, out of the 16 problems, insects and diseases infestation was identified as the major problem with PCI 429 followed by dropping of fruits and flowers with PCI 409. Lack of better varieties/ Seedling/ grafts, modern technology and climate change was also three major problems with PCI 387, 193 and 276 respectively. Cost and return analysis of mango production revealed that 10 mango varieties are founds as profitable with the higher working investment and human labor development. Cultivator had to spend 106659 taka for one hectors of land or 120 mango trees and average profit was 299010. Average profit from mango cultivation (299010Tk/ha) was higher than Average profit from onion cultivation (260412Tk/ha).Most farmers (about 87%) practiced intercropping with mango. the cost incurred by Harvesting, Sorting and Grading of mango cultivation was more than other crops. Although respondents certified that Rajshahi district is profitable in respect of mango production further study should be taken place with other variables and characteristics.</p> <p>Res.

We have found that 82% farmers are Muslim and 70% females are involved with goat farming. Survey showed that 47% goat farmer’s age range is (15-30 year) and 68% (46% female and 22% male) farmers are in primary standard level. Landless or small marginal farmers are involved with goat farming (37%). This study reflects that 54% farmer’s annual income is within 10,000 Tk whether 37% goat farmers earn between (10,000-20,000 Tk) per year. Only 9% farmers earn more than 20,000 Tk per year. 100% farmers in rural area rear their goat by semi intensive system; 82% and 18% farmers use kacha and paka floor respectively. 86% farmers supply concentrates feed with green grass whereas only 14% farmers do not supply any concentrate feed to their goat. Farmers supplied 2.63±0.05kg/day green grass, 60.00±5.86g/day concentrate and 0.62±0.03kg/day tree leaves per animal during lactation stage. Maximum (61%) farmers have more than 10 goat and 25% have 5-10 no. of goat. The body wt of buckling, doeling, buck and doe were 6.12± 0.04kg, 5.92± 0.06 kg, 8.45±0.10 kg and 7.44±0.04 kg respectively. Most of the farmers (84%) use natural and few farmers (16%) use artificial insemination to their doe. The incidence of pneumonia (61%), fever (43%), diarrhoea (42%) and anorexia (60%) are high in up to 1 month of age. Incidence of goat pox (58%) and alopecia (54%) are high in the age of above 9 months and ectoparasitic infestations (51%) are high in the age of (1-9) months. From above discussions we can concluded that Socio economic condition of farmers in rural area of North Bengal region is not so good. To enhance the production potential of the breed it is essential to introduce superior technologies and to create necessary facilities of improved practices in goat keeping.</p> <p>Res.

Fish captured from the Jamuna river were marketed through three types of market viz. auction market/arat, wholesale market and retail market. Operators of the fish market were the fishermen, faria, aratders, paikers or baparies, whole sellers and retailers. Ten channels were identified through which fish of the Jamuna river were shifted from the fishermen to the consumers. The shortest channel was the fishermen to consumers while the longest one was the fishermen→faria→aratders→paikers→whole seller→retailer→consumers. The highest price of fish (BDT 560/kg) was recorded for Wallago attu in retail market followed by BDT 500/kg for Tenualosa ilisha and Bagarious bagarious while, five small indigenous species (SIS) Tetraodon cutcutia, Chanda nama, Parambassis lala, Parambassis ranga, and Esomus danricus got the lowest price in retail market. Icing, weighing, transportation, capital supply were required in fish marketing channels as supporting function to overcome crisis. Major constrains prevailing in the fish marketing channels were reducing fishing areas, decreasing fish catch per day per fishermen, disturbance by illegal seasonal fishermen, lack of bargaining power and market information, lack of proper fish storage and preservation facilities in the fishing craft and fish markets, wastage of fish due to spoiling during transportation, sanitations, drainage and management problems within the market areas.</p> <p>Res.

Production of all male tilapia is being practiced by the hatcheries of Bangladesh mainly by administering androgen hormones (particularly 17-α-methyl-testosterone) with feed in a mixture of undifferentiated fry for about a month. The direct application of hormone to such food chain often arises question in respect to public health and safety. The alternative to this is the production of putative supermales, a rather safe but longer procedure to obtain all male progeny. However, sex determination system in tilapia is fairly complex. Recent developments have resulted in a linkage map and genetic markers that can be used to analyze the sex determination system. For genetic analysis of different genotypes of fish, microsatellite DNA marker ARO120 and ARO121 were used for studying the inheritance pattern for possible sex linkage using Polyacrylamide gel electrophoresis. In case of ARO120, it was observed that the Dam XX was heterozygous; 11 out of 22 female progeny and 10 out of 22 male progeny were found to be heterozygous. In case of ARO121, it was observed that the Dam XX was heterozygous; 16 out of 22 female progeny and 20 out of 22 male progeny were found to be heterozygous. Though the marker polymorphisms were observed in this study, these were excluded from the sexlinkage study due to limited extent of information as sex-linked markers in Nile tilapia BFRI strain. This study provides a baseline for further research using other suitable polymorphic markers for assisting marker-assisted selection.</p> <p>Res. Agric., Livest.

Total lengths were 26.71 ± 0.85, 34.82 ± 0.82 and 43.78 ± 0.9, standard lengths were 26.27 ± 0.64, 29.43 ± 0.73 and 37.35 ± 0.91 for (20-30cm, 30-40 cm and 40-50 cm), respectively. Numbers of rays on dorsal fin were 7.5 ± 0.18, 7.8 ± 0.25 and 8.08 ± 0.05; numbers of scales were 5, 5 and 5 ± 17 for (20-30cm, 30-40 cm and 40-50 cm) lengths, respectively. The values of WBC were (1345.1 ± 314.22, 15133564 ± 2851414 and 19536900 ± 4594589 /mm<sup>3</sup>), the values of RBC were recorded as 13885000 ± 2653096, 1317132.3 ± 91643.55 and 2077000 ± 139033/mm<sup>3</sup> . The values of Hemoglobin (Hb) were 11 ± 0.95, 6.24±0.18 and 6.96 ± 0.25 g/dl. The values of PCV of were 45.4 ± 3.2, 25.6 ± 0.52 and 27.9 ± 0.97 % for (20-30cm, 30-40 cm and 40-50 cm) length, respectively. According to the results in the present study suggest that mersitic characters were affected by many environmental factors such as light, temperature and dissolved oxygen, while hematological parameters were affected by age.</p> <p>Res.
