Mung-6)". The experimental soil pH was 5.71 and organic carbon content was 0.68%. Three levels of zinc (0, 4 and 8 kg Zn hi') and four levels of sulfur (0, 15,25 and 35 kg S hi') were used in the study. Levels of these two nutrient elements made 12 treatment combinations. The experiment was carried out in Randomized complete block design (RCBD) with three replications. The results revealed that seed and stover yield of mungbean increased with increasing levels of sulphur and zinc up to certain level. The maximum significant seed and stover yields were obtained with the treatment combination Zn2S2 (8 kg Zn hi'+ 25kg S hi'). This perticular treatment combination gave the highest seed yield (2.657 t ha"), stover yield (1.623 t hi 5, plant height (57.20 cm), number of branch plant" (2.880). yield attributes like number of pods plant" (20.09), number of seeds pod" (12.47) and weight of 1000-seeds (44.72 g). On the other hand, minimum seed and stover yields were obtained with control condition. The N, P. K and S concentration of mungbean plant increased significantly from control to Zn2S2 (8 kg Zn hi'± 25kg S ha") treatment combination and again decreased with increasing sulfur more than 20 kg S hi'. Application of zinc and sulphur fcrtili7ers increased organic carbon. N. P. K and S status of post-harvest soil significantly.

There were three different levels of irrigation viz, no irrigation, once at 25 DAS and twice at 25 DAS and 53 DAS and three levels of sulphur viz. 15. 30 and 45 kg S ha". The experiment was laid out in split plot design with three replications assigning irrigation in the main plots and levels of sulphur in the subplot. Irrigation and sulphur significantly influenced the growth, development, yield and yield attributes of rapeseed. Plant height, number of primary branches per plant, secondary branches per plant. number of siliquae per plant, siliquae length, seeds per siliquae, seed yield and oil content was significantly influenced by both irrigation and sulphur. Among the irrigation treatments, two irrigation levels resulted the better growth parameters like plant height and yield components like number of primary branches per plant, secondary branches per plant, number of siliquae per plant, siliquae length. seeds per siliqua and seed yield. Irrigation levels also influenced the oil content. Twice irrigation levels showed the best performance in all respect. The highest seed yield 1505 kg hi' was obtained from twice irrigation levels while control treatment gave the lowest yield. The result revealed that application of 45 kg S hi' showed superior in all respect which is statistically similar to the application of 30 kg S ha" except oil content. The interaction effect of irrigation and sulphur revealed that twice irrigation levels in combination with 45 kg S ha" showed the best performance which was statistically similar to twice irrigations with 30 kg S hi'.

Sher-e-Bangla Agricultural University. Dhaka-1207 during l3oro rice cropping season (December 2012 to June2013) to observe the effect of salinity on two rice varieties BINA dhan 10 and BRRI dhan47. Five salinity levels viz. 0. 4, 8. 12 and 16 dSm1were imposed on the experiment. The experiment was set in Completely Randomized Desi (CR1)) having two factors with three replications. The results on the effect of morphological characters indicated that plant height, total tillers, effective tiller, number of non effective tiller, root dry weight, shoot dry weight. number of field grain, number of unfilled grain, panicle length and grain yield were influenced by the varieties. The tallest plant was found in cultivar BRRI dhan47. BINA dhan 10 achieved maximum number of total tiller, root dry weight (ROW). effective tillers hill'. panicle length, number of filled grain panicic". Among the two varieties the highest grain yield (3.40 g hill5 was found in cultivar BINA dhanl0 and the lowest yield (2.66 g hill') was recorded in BRRI dhan47. Among different salinity levels highest growth and yield contributing characters found at 0 dSm". The maximum number of total tiller hill', effective tiller hill'. RDW and SDW. panicle length and number of filled grain panicle' were found at 0 dSm'. lie highest grain yield (6.09 g hill') was also recorded at control treatment. Among the combined effects of varieties and salinity levels, highest grain yield (6.86 g hiw') was obtained from BINA dhan 10 at 0 dSm' and at 4. 8. 12 dSm' salinity levels BINA dhan 10 should better result than BRRI dhan47. Among the two varieties. K content was highest in BINA dhan 10 than BRRI dhan47. In both varieties K content decreased significantly with the increasing salinity level. Na content was higher in BRRI dhan47 than BINA dhan 10. In both varieties it increased significantly with the increasing salinity level.

During the experiment. three different organic fertilizers (Poultry manure, Vermicompost and Farm Yard Manure) were combined with four doses of inorganic fertilizers (25%, 50%, 75% and 100% of optimum dose) and one control treatment using no fertilizer and one treatment using only 100% of the optimum doses were included. At 30 DAS and at harvest highest plant height, number of leaves plani' and branches plani' were found from the combination of Vermicompost and 100% inorganic fertilizer which was statistically similar or closely followed by Vermicompost and 75% inorganic fertilizer treatment. Maximum numbers of pods plant4, seeds podS ' and seeds plant4 were recorded in Vermicompost and 100% inorganic fertilizer and it was closely followed by Vermicompost and 75% inorganic fertilizer. Highest seed yield plant". 1000-seed weight and seed yield hi' was recorded in Vermicompost + 100% of optimum dose of inorganic fertilizer and it was statistically similar with the treatment of Vermicompost + 75% of optimum dose of inorganic fertilizer. It was observed that, for the above parameters: Poultry manure -i- 100% of optimum dose of inorganic fertilizer and Farm Yard Manure + 100% of optimum dose of inorganic fertilizer showed better results than sole 100% inorganic fertilizer. In some cases, Poultry manure + 75% of optimum dose of inorganic fertilizer and Farm Yard Manure + 75% of optimum dose of inorganic fertilizer also performed better than sole 100% inorganic fertilizer. Lowest values for all of the growth and yield parameters obtained from the treatment using no fertilizer. Highest N and P contents in seed were recorded in Vermicompost + 100% of optimum dose of inorganic fertilizer and it was statistically similar with the application of Vermicompost + 75% of optimum dose of inorganic fertilizer. Highest K and S contents in seed were recorded in Vermicompost + 100% of optimum dose of inorganic fertilizer and it was followed by Farm Yard Manure + 100% of optimum dose of inorganic fertilizer. Vermicompost + 75% of optimum dose of inorganic fertilizer and Poultry manure ± 100% of optimum dose of inorganic fertilizer. Lowest N, P. K and S contents of mungbean seed were found from the treatment using no fertilizer. A Thesis Submitted to the Department of Agricultural Chemistry Sher-e-Bangla Agricultural University.
