Electrical Conductivity (EC) value of the study area showed that yield of many crops can be restricted in dry season due to salinity. Mean EC was slightly saline (5.93 dsm<sup>-1</sup>) in dry season and non- saline (0.61 dsm<sup>-1</sup>) in wet season. Ranges of pH were slightly acidic to slightly alkaline (6.2 to 7.5) in dry season and slightly acidic to neutral (5.7 to 6.9) in wet season. pH values indicate it was suitable for crop production. Mean Organic Matter (OM) status was low in both seasons (1.5 % in dry season and 1.6 % in wet season). Mean total N status was very low (0.08 %) in dry season and low (0.10 %) in wet season. Mean status of P in the study areas was low (8.08 <em>µgg<sup>-1</sup></em> soil) in dry season and very low (4.98 <em>µg</em>g<sup>-1</sup> soil) in wet season. Mean status of K, Ca, Mg, S and Zn were very high in both season of study area and this was may be due to excessive fertilizer use and inherent properties of soil in the agricultural land. Mean status of B was high in Tala in both season and in Shyamnagar was high in dry season and optimum in wet season. To test the significance of the pair of parameters p-value has been measured. Pearson’s correlations among the different parameters were done to identify the highly correlated and interrelated soil quality parameters. EC showed significant and positive correlation with Potassium, Sulphur and Zinc in dry season. Although chemical properties of soil at Shyamnagar and Talaupazila was not found similar and optimum level but it was found that the chemical properties of soil of wet season more suitable than the dry season because of soil salinity.</p> <p><strong><em>Progressive Agriculture 30 (2): </em></strong><strong><em>157-164, 2019</em></strong></p> 2019-08-18T07:43:22+00:00 ##submission.copyrightStatement## Interactive effects of irrigation and flobond on growth and yield of BRRI dhan29 2020-01-22T17:37:53+00:00 MZ Rahman R Ahmed A Shila MM Hasan MHK Howlader <p>The experiment was conducted at the Research Farm of Patuakhali Science and Technology University (PSTU), Patuakhali during the period from December-May of 2015 to evaluate the effect of irrigation and soil conditioner on growth and yield of BRRI dhan29. A modern HYV rice variety BRRI dhan29 was grown under four different frequency of irrigation viz., four times, six times, eight times and ten times with five rates of flobond(soil conditioner), viz., 0.0, 5.0, 10.0, 15.0 and 20.0 per plot. The experiment was laid out in a split plot design with four replications. Irrigation and rate of soil conditioner and their interaction significantly influenced the yield contributing and other crop characters. It was observed that the highest grain yield (7.08 t ha-1) was obtained from eight times irrigations, but the highest straw yield was obtained from ten times irrigations (6.706 t ha-1).The highest grain yield (7.21 t ha-1) was obtained with 10g Flobond per plot but the highest straw yield (6.29 t ha-1) was obtained with no Flobond. However, the highest grain yield (8.38 t ha-1) was obtained with eight times irrigation coupled with 10g of Flobond per plot as soil conditioner and the lowest one (5.5 t ha-1) was obtained in four times irrigation and no Flobond. So, eight times irrigation coupled with 10g of Flobond per plot as soil conditioner was the best combination for obtaining best yield.</p> <p><strong><em>Progressive Agriculture 30 (2): </em></strong><strong><em>165-172, 2019</em></strong></p> 2019-08-18T07:43:31+00:00 ##submission.copyrightStatement## Control fruit fly for profitable sweet gourd production 2020-01-22T17:37:41+00:00 M Hossain MI Mia MAAH Talukder UK Laily MMU Haque J Khandakar <p>A field experiment was conducted in the farmer’s field at Salaipur, Mithapukur, OFRD, Rangpur during 2015-2016 to control cucurbit fruit fly effectively through the use of sex pheromone trap.

Aim of the current experiment was to evaluate the susceptible and resistant individuals to nematode infection within the population of Yichang white goat (YWG) and assess the differential level of mRNA expression of those candidate genes in the abomasal tissues of susceptible and resistant goats. Fecal egg count (FEC) was determined using a modified McMaster technique, and the hematological parameter was measured by Mindray auto hematology analyzer. Phenotype data were collected and analyzed using a generalized linear model with SAS statistical program. Field investigate revealed that the prevalence (76%) with maxium parasite load (734.34±84.21epg) of<em> H</em><em>. contortus</em> occurred in August within the experimental flock&nbsp; FEC in resistant group (103.38±1.20epg) and susceptible group (1180.25±43.53epg) group &nbsp;demonstrated the presence of&nbsp; two distinct goat populations within this breed. Four resistant and four susceptible goats were selected from each group. The parasite infection was established by artificially challenge with 5000 infective L<sub>3</sub> larvae of <em>H. contortus.</em> Abomasal tissues were collected from all experimental goats after 42 days of post-infection. FEC, Body weight, packed cell volume, and hemoglobin value were significantly different (<em>P</em> &lt; 0.01) between resistant and susceptible group of goats. Quantitative real-time PCR in abomasal tissues revealed that the expression level of mRNA for <em>NOD1 </em>(<em>P </em>&lt; 0.00001), <em>IFNG </em>(<em>P</em> &lt; 0.0001), <em>NLRP9, TLR8</em>,<em> IL32,</em> (<em>P</em> &lt; 0.001) and <em>IGF1</em> (<em>P</em> &lt; 0.01) was higher in resistant goat compared to susceptible, except <em>SFTPA1</em>. These findings revealed the presence of genetic resistant individuals to <em>H. contortus</em> within the goat breed and expression of <em>NOD1</em> and&nbsp; <em>NLRP9 </em>genes proved the positive finding of our previous study. Presence of genetic resistant individuals in Yichang white goat YWG breed could be a good candidate for selective breeding and highly expressed genes related to resistant could be used as biomarkers to develop <em>H. contortus</em> resistant goat population.</p> <p><strong><em>Progressive Agriculture 30 (2): </em></strong><strong><em>194-208, 2019</em></strong></p> 2019-08-18T07:44:11+00:00 ##submission.copyrightStatement## Design and fabrication of Windchill for low cost vegetable preservation 2020-01-22T17:36:52+00:00 SS Tunny MAE Rabbani MS Basir <p>In Bangladesh, every year a huge amount of vegetables are being lost after harvesting from the field due to inadequate storage facilities at farmers’ level. Considering this a low cost storage chamber, windchill was designed and fabricated that consumes low power to operate by a 12V duct fan. The average temperature inside the chamber at no load condition was found 24.7<sup>◦</sup>C with a relative humidity of 77.2% while the outside temperature and relative humidity were 28.9<sup>◦</sup>C and 54%, respectively. Performance of the chamber was tested keeping vegetables inside the chamber for four and five days during pre-test and bulk load test, respectively. During bulk load test the temperature and relative humidity inside the chamber were 24.7<sup>◦</sup>C and 77.1%, respectively while outside the chamber, these were 28.8<sup>◦</sup>C and 52.8%, respectively. After four days weight loss percentage inside the chamber at pre-test condition were 1.76% (tomato), 3.53% (brinjal), 5.2% (greenchili) and 18.16% (red amaranth) while weight loss outside the chamber were 4.18% (tomato), 9.52% (brinjal), 14.44% (greenchili) and 49.44% (red amaranth). Weight loss percentage at bulk load condition inside the chamber was 1.46% while outside the chamber was 15.15% at 5<sup>th</sup> day. Physical appearance of vegetables kept inside the chamber was also much better than those kept outside the chamber. The panel test result for evaluating physical appearance was found satisfactory based on their acceptance level after preservation. The initial construction cost of the full unit was Tk. 6010 which was found cost effective for farmers to store their vegetables for several days after harvesting.</p> <p><strong><em>Progressive Agriculture 30 (2): </em></strong><strong><em>209-218, 2019</em></strong></p> 2019-08-18T07:44:19+00:00 ##submission.copyrightStatement## Study of ready to use onion paste for prolonged shelf life 2020-01-22T17:36:40+00:00 S Arefin MHR Bhuiyan N Yeasmen MA Islam M Shams Ud Din <p>This paper attempts to show the effect of preservatives and storage on the chemical, sensorial and microbial aspect of ready to use (RtU) onion paste<strong>, </strong>stored at two conditions i.e. ambient temperature (AT: 30±3<sup>0</sup>C) and refrigerated temperature (RT: 5±1<sup>0</sup>C) over a period of 180 days after treating with preservatives i.e. Potassium metabisulphites (KMS), Sodium benzoate (SB) and Citric acid (CA) at two levels i.e. 750 and 1000 ppm respectively. In the context of chemical aspect, a throughout observations over 180 days with 60 days interval showed negligible changes in chemical constituents of RtU onion paste both at AT and RT conditions with a little exception. Over the period p<sup>H </sup>slightly increased for both the storage conditions. Towards the sensorial point of view, use of preservatives in RtU onion paste resulted in the acceptance of color, flavor and texture up to 60 and 120 days of storage at AT and RT, respectively. To improve the effect of preservatives, mixture of them (KMS &amp; CA; SB &amp; CA) was also applied into to the sample (onion paste) besides the individual application. As a consequence, sensorial quality was better sustained by the addition of CA (0.8%) with other preservatives in comparison to the samples without CA. Onion paste, in specific, treated with 1000 ppm KMS &amp; 0.8% citric acid stored both at AT and RT condition retained the most acceptable quality attributes compared to other treatments. However, onion paste without any preservative (control) was found acceptable only up to 20 days of storage at RT while storage at AT condition resulted in the more worse situation (acceptable up to 5 days). Total bacterial count was found in the lowest amount in RtU onion paste treated with the combination of KMS (1000 ppm) and CA (0.8%).</p> <p><strong><em>Progressive Agriculture 30 (2): </em></strong><strong><em>219-226, 2019</em></strong></p> 2019-08-18T07:44:30+00:00 ##submission.copyrightStatement## Effect of sugar and starch on chemical and organoleptic parameters of pineapple bar during storage 2020-01-22T17:36:26+00:00 EH Biswas MA Islam R Ferdowsi YA Yusof MG Aziz <p>The aim of this study was to assess the effect of major ingredients on the changes of fundamental quality parameters of pineapple fruit bar during preparation and storage.&nbsp; Four samples were prepared by using Extreme Vertex mixture taking three major ingredients namely fruit pulp, sugar and starch content as factors and non-enzymatic browning data and overall acceptability as responses. The result revealed that compositional differences of different ingredients in formulation fitted to the quadratic linear model at&nbsp;&nbsp; p&lt;0.05. Among the four formulations the liking intensity of formulation F<sub>4</sub> containing pineapple pulp 86%, starch 2% and sugar 12% showed the highest scores in all of the studied sensory parameters followed by F<sub>2</sub>, F<sub>3</sub> and F<sub>1</sub>. Among the components studied, sugars irrespective of sources are the main components responsible for non-enzymatic browning whereas starch contributes to retain color by forming a protecting film around the reducing groups.</p> <p><strong><em>Progressive Agriculture 30 (2): </em></strong><strong><em>227-237, 2019</em></strong></p> 2019-08-18T07:44:41+00:00 ##submission.copyrightStatement##
