Field performance of daughter plant of strawberry as influenced by tricho-compost and tricho-leachate 2019-07-20T13:11:53+00:00 QM Ahmed MN Islam MS Nahar AKMA Hoque MM Rahman <p>Effect of soil incorporated Tricho-compost @ 5.5 t/ha (T1) and foliar spray of Tricho-leachate @ 4 ml/l at 15 days interval (T2) each alone or in combination (T3) were evaluated on mortality of strawberry plant in the maintenance nursery and growth and development of daughter plants in the main filed. Traditional practice of maintenance of plants in the nursery bed was considered as control (T4). The study was conducted at the Regional Horticultural Research Station, Bangladesh Agricultural Research Institute, Sibpur, Narsingdi, during June 2015 to March 2016 and BARI Strawberry-1 was used in the study. The lowest mortality (6.67%) in the nursery bed was recorded in saplings treated by T3, while the highest mortality (16.67%) was recorded in the control plot (T4) and the trend was also followed in the main field. Days to flowering (47.67) and days to first harvest (71.67) of saplings treated by T1 were earlier as compared to that of saplings of control plot (60.67 and 93.33 respectively). The maximum harvest duration was recorded in saplings treated by Tricho-compost (74 days) followed by T2 (61.33 days) and T3 (59.33 days). Total Soluble Solid (TSS) of fruits were also improved when the plants were treated by Tricho-products. The maximum fruit yield (621.68g per plant) was recorded from T3; while, the lowest yield (396.83g per plant) was recorded in saplings treated by Tricho-leachate @ 4ml/l.</p> <p>Bangladesh J. Agril.

This field experiment was initiated to achieve improve and sustainable productivity of an intensive wheat-maize-rice cropping system with improved management of natural resources. Four levels of nutrient managements were tested under four soil management treatments starting with wheat crop sown in November 2009 and ending with the harvest of 8<sup>th</sup> wheat crop in the system during March 2017. Yield and yield contributing characters of component crops and soil properties were studied following standard methods. Soil management treatment of rice straw mulch application in reduced till-bed or well-till flat soil upon wheat sowing was equally effective in conserving soil moisture, enhancing wheat root development, reducing weed growth and thereby positively influenced spikes/m2 and finally wheat yield. Similarly, wheat straw mulch application contributed to ears/m<sup>2</sup> and grain yield of maize. Nutrient levels of recommended fertilizers plus 5.0 t/ha cowdung resulted in yield improvement of wheat and maize throughout the years. However, neither nutrient management nor soil management alone but the combination of recommended fertilizers with 5 t/ha cowdung couple with rice straw mulching in wheat and wheat straw mulching in maize resulted in maximum wheat and maize yield over the years. Rice yield was similar for different treatment combinations until the 4th cropping cycle and thereafter rice yield was also improved by the residual effect of straw mulches. Crop residue mulching along with addition of organic and inorganic fertilizers was found to be a promising soil management technology for achieving sustainable increased productivity of wheat-maize-rice system.</p> <p>Bangladesh J.

Under high temperature maximum chalkiness rate was 61.11% and minimum was 22.59% under low temperature treatment. The lowest head rice rate was 42.76% under high temperature treatment followed by 49.91% in the control, while the highest rate was 62.33% under low temperature treatment. Maximum grain filling rate (Gmax) was found highest (1.69 mg/day) in the high temperature and average grain filling rate (Gavg) was found highest (1.36 mg/day) under the control. The activity of SuSy, ADPG-Ppase, SSS and GBSS were decreased gradually from 14 to 35 days after flowering (DAF). Irrespective of the treatments, an increasing trend of ADPG-Ppase activity was observed from 7 to 14 DAF and then declined. Correlation between the chalkiness and the enzymes activity of SuSy, ADPG-Ppase and SSS were significantly negative at 21, 28 and 35 DAFs, i.e., higher activity of SuSy, ADPG-Ppase and SSS at the mid-late to the late caryopsis development stage mediated by low temperature treatment played an important role for the reduction of chalkiness. The correlation between GBSS activity and chalkiness was significantly negative and stronger at 14, 21 and 28 DAF indicating that GBSS played a cardinal role to reduce chalkiness in the mid to mid-late stage of rice grain development. Significantly negative correlation was found between starch branching enzyme (SBE) and chalkiness at 21, 28 and 35 DAF, i.e., the higher SBE activity under low temperature treatment at the later grain filling stage also had a positive role in reduction of chalkiness.</p> <p>Bangladesh J.

Hepper) in a Randomized Complete Block Design with 3 replications at the Plant Genetic Resources Centre of BARI Gazipur during March to June 2012 to know the diversity of germplasm. Two to four classes were observed among the 14 qualitative characters. Green and purple colours were found in epicotyl, petiole and stem. Light green to dark green was found in case of leaf and immature pods. Erect, semi-erect and spreading growth habit along with indeterminate and determinate growth pattern were observed. Ovate, ovate-lanceolate and rhombic terminal leaflet shape were found. Erect to sub-erect pod attachment to peduncle with glabrous to densely pubescent pods were found. The accessions showed black and brown mature pods having hook and knob types of pod beak shape. Black, brown, grayed-orange and yellow-green seed colours were observed among the blackgram accessions. Low to high phenotypic diversity index (0.12 to 0.91) were found among the qualitative characters. All the accessions exhibited purple hypocotyl, none twining tendency, glabrous leaf pubescence, abundant leafiness, very light green calyx, yellow flower, drum-shaped seeds, absent seed luster and non-concave seed hilum. Number of seeds per pod ranged from 5 to 7 and hundred seed weight ranged from 1.83 to 4.49 g. The highest PCV was observed in branch length (32.65%) and the lowest PCV was found in pod length (6.99%). The accessions were grouped into five clusters. Accessions collected from the same districts felt into different clusters. The inter and intra cluster distances ranged from 3.37 to 11.38 and 0.30 to 1.17, respectively. The maximum number of pods per plant, pod length and 100-seed weight was found in cluster IV.

Analysis of variance for combining ability showed that mean square (MS) due to GCA &amp; SCA were highly significant for all characters except GCA in plant height, cob length and 1000 grain weight and SCA in maturity and row/cob indicated that all but mentioned traits were governed by both additive and non-additive gene action. Variances due to GCA were higher for all characters except thousand grain weight revealed that the predominance of additive gene action for all characters except thousand grain weight. Parent CML 487 and Ki 21 were the best general combiner for yield and most of the yield contributing characters. Parent BMZ 57 &amp; BMZ 15 were the best general combiner for dwarf &amp; earliness in plant. Among all the crosses CML 473 × Ki 21, CML 487 × Ki 21 and CML 429 × BIL 182 exhibited significant positive SCA effect for grain yield. The cross CML 429 × BIL 182 may be considered as the best cross with recorded significant mean value and desired SCA for traits like 1000 grain weight, yield (t/ha), days to 50% pollen shedding, days to 50% silking, plant height, ear height and days to maturity. The promising single crosses with significant and positive SCA could be used for variety development after verifying them across locations.</p> <p>Bangladesh J. Agril.

A total of 280 respondents having 40 respondents from each district were selected randomly for the study. The maximum number of vegetable growers belonged to the age group of 21-40, which is about 50%. About 41% and 25% of farmers accomplished their primary and secondary education in the study areas. Tomato fruit had the highest yield (27.74 tha-1) whereas the highest gross margin was attained from country bean 4,06,832 Tk.ha<sup>-1</sup>. Almost all of the vegetable growers were used synthetic pesticides (chemical group of Cypermethrin, Emamectin Benzoate, Chlorpyriphos, Carbendazim, Lambda Cyhalothrin, Mencozeb etc.) for protecting their crops from pests and most of them used own hand pump sprayer. Farmers of the study areas applied synthetic pesticides frequently with much higher dosages (8-30 times) than the recommendation. Few farmers practice Integrated Pest Management (IPM) for their crops. Seventy five percent farmers had protective measure during insecticide-pesticide spray and about 40% growers felt uncomfortable after hand spray to the crops. Most of the tomato growers in the study areas (Rajshahi and Jashore) were applied Plant Growth Regulator (PGR)/ripening agents mainly Ethephon @ 2500-8000ppm before 1-3 days of harvest in immature green tomato (1-4 times) for uniform color development to get higher price in the early market. Few traders (10-15%) were applied Ethephon in premature vegetables after harvest. It is strongly recommended to use IPM technology for controlling insects and pest and to create awareness regarding pesticides use practice and safety precautions.</p> <p>Bangladesh J. Agril.

BARI Karola-1. Eeleven treatments comprising five concentrations each of gibberellic acid (50, 100, 150, 200 and 300 ppm) and naphthalene acidic acid (50, 100, 150, 200 and 300 ppm) along with distilled water considered as control were evaluated in randomized complete block design with three replications. Gibberellic acid (GA3) and Naphthalene acidic acid (NAA) were sprayed at 4 leaf stage; second spray was done at 35-38 DAS and third spray done at flowering stage. All the treatments improved the flowering and yield characters over control. Foliar spray of NAA @ 150 ppm and 200 ppm was found better in terms of sex expression, yield and yield attributes of bitter gourd as compared to control and other treatments. Spray of NAA @ 150 ppm gave the lowest number of male flowers and the highest number of female flowers thereby produced the lowest sex ratio (male:female). Number of fruits/plant, individual fruit weight and fruit yield/plant were also found maximum from NAA 150 ppm. Maximum fruit yield was recorded with the application of NAA @ 150 ppm. Spraying of NAA @ 150 ppm gave the maximum gross return and net return with the highest BCR of 3.17.</p> <p>Bangladesh J. Agril.

Analysis of variance revealed significant differences among the restorer lines for all the traits studied.The phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) for all the traits indicating the presence of little environmental influence in the phenotypic expression. Heritability estimate was found high for all the yield contributing traits. High heritability along with high genetic advance as per cent of mean was recorded for secondary branches per panicle followed by number of effective tillers, flag leaf area and panicle weight. Contrary, days to flowering and days to maturity showed high heritability coupled with low genetic advance as per cent of mean. Pearson correlation revealed grain yield had positive association with number of effective tillers per hill, panicle length, spikelet fertility, flag leaf area, plant height and thousand grain weights. Mentioned characters also found positive association with yield in both genotypic and phenotypic level. Spikelet fertility, number of secondary branches per panicle, thousand grain weights and number of effective tiller possessed higher positive direct effect on grain yield. It indicated the importance of these traits as selection criteria of yield improvement in hybrid rice programme.</p> <p>Bangladesh J. Agril.

Trade-off analysis for multidimensional impact assessment (TOA-MD) model was used in the study with a combination of simulated baseline production and future simulated yield using Decision Support Systems for Agro-technology Transfer (DSSAT) and Agricultural Production Systems SIMulator (APSIM) in rice and wheat production system. Five different climate scenarios of Global Circulation Models (GCMs) were considered. The projections showed to have a negative economic impact between 50 and 82% for the difference in the magnitude and in the impact of different GCMs which was not possible to overcome. The survey revealed that northwest region of Bangladesh is likely to be affected by climate change and has high levels of vulnerability due to limited access to alternative livelihood activities other than farming. Simulation results showed no additional economic gain from wheat cultivation under changed climatic conditions, but increased economic profit was obtained from rice cultivation due to increased productivity trend. Therefore, study suggests an adaptation package of 50 mm additional irrigation water for wheat cultivation that could be an appropriate strategy to mitigate climate change risk in wheat cultivation. This practice had a positive impact on projected per capita income gains of about 2.05%in the study area and reduced poverty rate by about 1.99%. The study also revealed that prediction of the APSIM model for adaptation impact of climate change on economic return and per capita income of farmers was superior to DSSAT model.</p> <p>Bangladesh J.

Krishibid Hybrid-1 and Atlas-70) to foliar application of GA3 and NAA with different concentrations. The experiment was laid out in a Randomized Complete block Design with three replications. The experiment consisted of eight treatments viz., three levels of GA3 (at 50, 75 and 100 ppm) and four levels of NAA (at 40, 60, 80 and 100 ppm) along with distilled water as control. The varieties Krishibid Hybrid-1 and Atlas-70 were used in 2015-16 and 2016-17, respectively. Foliar spray of GA<sub>3</sub> and NAA was given at 25 and 45 days after transplanting of seedling. The results of the investigation indicated significant differences among the treatments on most of the parameters studied. In Krishibid Hybrid-1, application of 50 ppm GA<sub>3</sub> and 60 ppm NAA increased plant height, plant spread, number of leaves, chlorophyll content, head height, head diameter, single head weight without unfolded leaves as well as head yield (81.18 t/ha for 50 ppm GA<sub>3</sub> and 78.57 t/ha for 60 ppm NAA) than the control (67.29 t/ha) and other treatments. But, in Atlas-70, application of 75 ppm GA<sub>3</sub> gave the maximum values of most of the growth parameters, yield components and yield (102.40 t/ha), which was followed by 50 ppm GA<sub>3</sub> (94.96 t/ha). In Krishibid Hybrid-1, application of 60 ppm NAA gave the highest benefit-cost ratio (BCR) of 3.63 followed by 75 ppm GA3 (3.59) while in Atlas-70, 75 ppm GA<sub>3</sub> recorded the highest BCR of 4.79 followed by 50 ppm GA<sub>3</sub> (4.54) and 60 ppm NAA (4.37). Therefore, application of GA<sub>3</sub> @ 50-75 ppm or NAA @ 60 ppm concentration can be recommended for increasing the yield of cabbage with higher return.</p> <p>Bangladesh J. Agril.
