An experiment was conducted to evaluate lablab bean genotypes for off-season production under Sylhet condition during January to October 2015 at the experimental field of Horticulture Department of Sylhet Agricultural University. Three photo-insensitive lablab bean genotypes viz., BP003, SB003 and SB010 were evaluated at three different sowing dates of 15 January, 15 March and 15 May, 2015 under RCB design with three replications with a view to identify suitable genotypes and their sowing dates in Sylhet condition. Among the genotypes, BP003 produced the maximum number of pods per plant (283) and pod yield/plant (1.64 kg/plant) which was closely followed by the genotype SB003 (1.60 kg/plant). The highest individual pod weight (5.79 g) and pod length (10.9 cm) were recorded from SB003 which were identical to that of BP003 (5.53 g and 9.41 cm, respectively). The genotype BP003 had the highest pod breadth (2.96 cm). The genotype SB010 exhibited the lowest individual pod weight (4.72 g), pod length (8.31 cm) and pod breadth (2.66 cm) among the genotypes. Sowing dates had significant influence on pod production during offseason production. The highest number of pods per plant (416.89) was recorded from the plants of 15 March sowing while it was 192.56 and 166.44 for January 15 and May 15 sowing, respectively. Similar trend was also observed for pod yield per plant. The highest pod yield per plant (2.20 kg) was recorded from March 15 sowing while it was 1.14 kg per plant for January sowing and 0.85 kg per plant for 15 May sowing.Yields of pod at January and May sowing were much lower than that of March sowing. The crop sown in January experienced much colder situation caused slow initial vegetative growth and the plants grown from May sowing were largely affected by heavy rain during the month of July - August might be the reason for low yield compared to that of March sowing. Significant interactions were found between genotypes and sowing dates in case of off season country bean production in respect to yield and yield attributes. The highest number of pod per plant (474.00) was harvested from the genotype BP003 when grown from 15 March sowing followed by SB003 grown from 15 March sowing Similar trend also found in case of pod yield per plant. The pod yield per plant was the maximum (2.80 kg) for the treatment combination of BP003 grown from 15 March while it was the minimum (0.68 kg) for SB010 when coupled with 15 May sowing. 2016-12-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/497 DEVELOPMENT OF PRODUCTION TECHNOLOGY AND ADAPTATION OF SWEET PEPPER IN SYLHET REGION MIA, MD. RATAN Two different studies including evaluation of production technology of sweet pepper at the experimental field of Sylhet Agricultural University and adaptation of sweet pepper at the farmer‘s field of Sylhet and Habiganj districts were made during the winter season of 2014-2015. For on station evaluation of production technology, various tunnel covers including fine net, fine net + polythene covering, coarse net, coarse net + polythene covering, only polythene covering and open field condition were used for BARI Mistimorich-1 cultivation under RCB design with three replications. For on farm adaptive trials, BARI Mistimorich-1 was grown under three protective systems of net+polythene, only net and open field condition under selected farmers from Habiganj and Sylhet districts. On station evaluation of production technology revealed that tunnel covers had significant influence on growth and yield of sweet pepper. The highest number of fruits per plant was recorded (11.35) from the plant grown under fine net+polythene protected system followed by coarse net+polythene protected system (9.77) while it was the minimum for open condition (4.63). Individual fruit weight was also largely affected due to protective systems. The highest individual fruit weight was recorded from the plants grown under fine net system (106.0 g) while it was the lowest for the plants grown in open field condition (59.0 g). The corresponding fruit yield per plant was also the highest (1.117 kg/plant) when the crops grown under fine net+polythene protection followed by the plants grown under coarse net+polythene protection (0.902 kg/plant). Results revealed that the yield of sweet pepper under protected condition was higher compared to that of plants grown under open field condition (0.268 kg/plant). Yield (13324.06 kg/acre) and benefit cost ratio (BCR) were also highest (5.20) in fine net+polythene protection system than open systems. Variation in fruit yield and yield performance of sweet pepper was noticed among different farmers and protective structures. Production of sweet pepper under net+ polythene or only net protected condition for all farmers was much higher compared to that of open field condition. In this on farm adaptive trial, the mean highest number of fruits/plant (9.72) was recorded from the plant grown under net+polythene followed by the crops grown from only net protective structure (8.76). The corresponding fruit yield was also the highest (134 kg/decimal) when the crops grown under net+polythene protection followed by the plant grown from only net protection (115 kg/decimal), while the average yield/decimal was 100 kg. Economic analysis revealed that the BCR was maximum (5.06) for the sweet pepper grown from only net protection but gross income was maximum (14740 Tk/decimal) for net+polythene protection. It was due to the higher cost of production (4200 Tk/decimal) under net+polythene protection system compared to only net protection (2500 Tk/decimal) system. Thus, use of only net protection might be more profitable for sweet pepper production in Sylhet region. 2016-12-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/453 EVALUATION OF LABLAB BEAN GENOTYPES IN EARLY AND LATEPLANTING CONDITIONS FOR POD AND SEED PRODUCTION Alam, Mohammad Shaheen The present experiment was conducted with a view to evaluating pod and seed production of eight lablab bean genotypes viz. SB003, SB010, SB011, BP003, IPSA Sheem-2, Auto, Rupvan and Kanchan during winter season from July, 2014 to February, 2015 at the experimental field of Horticulture Department, Sylhet Agricultural University (SAU), Sylhet. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Among the genotypes, variation in relation to petiole length, cotyledon color, main stem pigmentation, leaflet size and shape, flower color, inflorescence length, pod color, pod size and shape, seed color, seed size and shape etc. was observed. During early planting in winter season, six genotypes viz. SB003, SB010, SB011, Auto, Rupvan and Kanchan were used for evaluating pod yield. Pod yield and yield attributes greatly varied among the genotypes. For days to first flowering, the highest was recorded for the genotype of SB003 (55 days) which was followed by the genotype of Kanchan (54 days). The lowest was recorded for the genotypes of SB010 and SB011 (51 days). The number of green seeds per pod was almost similar. It was ranged from 4.6 cm (SB011) to 4.2 cm (Rupvan). The highest number of pod per plant was recorded for the genotype of Kanchan (202.7) while it was lowest for the genotype of SB011 (53.67). Among the genotypes, the highest individual pod weight was recorded from Auto (18.2 gm.) which was followed by Kanchan (9.6 gm.). It was lowest for the genotype SB010 (6.8 gm.). All the genotypes required almost 76 days to first harvest and harvesting duration was around 100 days. Harvesting was done in ten times. The highest pod yield was recorded from the genotype Auto (23.05 t/ha) which was followed by the genotype Kanchan (19.26 t/ha) while it was the lowest for the genotype SB011 (5.42 t/ha). During late planting in winter season, four genotypes viz. SB010, SB003, BP003 and IPSA Sheem-2 were used for evaluating seed yield. Days to first flowering for all genotypes was recorded 46 days except SB003 (41 days). Among the genotypes, first harvest was done in 84 days and harvesting duration was 71 days. In dry pod, eight times harvesting was done. Oval shape of seed was noted for all genotypes except IPSA Sheem-2 (round). The highest 100 seed weight was recorded from the genotype SB010 (35.67 gm.) while it was the lowest for the genotype IPSA Sheem-2 (27.0 gm.). Seed yield was the highest recorded from the genotype SB010 (1.75 t/ha) followed by the genotype BP003 (0.90 t/ha) while it was the lowest for the genotype SB003 (0.52 t/ha). During early planting in winter season, after first harvesting of pod 50 gm. pod was taken for nutritional analysis. After analysis, 100 gm. of Auto contain the highest Cu (30.56 ppm), Fe (244.44 ppm), Mn (81.48 ppm), B (121.2 ppm) and S (0.316 %) which was followed by the genotype SB011; Cu (23.62 ppm), Fe (188.88 ppm), Mn (62.96 ppm), B (66.0 ppm) and S (0.176 %). In case of Zn, it was the highest for 100 gm. SB003 (123.72 ppm) followed by the genotype SB011 (120.6 pm). The highest Ca was found for the genotype Auto (3.34 %) which was followed by the genotype SB003 (3.22 %). For 100 gm. Mg, it was the highest for SB011 (1.57 %) which was followed by the genotype SB003 (1.35 %). 2016-06-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/452 INFLUENCES OF SEEDLING TYPES AND HORMONE APPLICATION ON PRODUCTION PERFORMANCE OF TOMATO HYBRIDS IN SUMMER HOSAIN, MD.
