Aman Rice cv. BR 22 (kiron). The retransplanting dates were assigned in the plots in a Randomized Complete Block Design (RCBD) with 4 replications. The effect of transplanting and retransplanting dates were significant in respect to yield attributing characters like plant height, effective tillers/hill, ineffective tillers/hill, grains/panicle, sterile grains/panicle and thousand seed weight and also the nutrient uptake of rice plant. The first Transplanting on 16 th September have significantly highest grain yield (4.725 t/ha) whereas the lowest yield (3.375t/ha) was found in the last retransplanting on 16 October.

ALAM, MD. MONZUR A field experiment was conducted during March to June 2009 at the research field of Soil Science Division, Bangladesh Agricultural Research Institute 1 : Control : PKB, T 4 : Bradyrhizobium inoculant, T 5 : N, T 6 2 : PKMo, T : PKMo + Bradyrhizobium Inoculant, T : PKB + Bradyrhizobium Inoculant, T 8 : NPKMo, T 9 : NPKB, T 10 : PKMoB, T : PKMoB + Bradyrhizobium Inoculant and T : NPKMoB. After 35 and 50 days of sowing, 5 plants were uprooted from each plot in each days of nodule collection to study nodulation, dry matter production and plant growth. At maturity, yield and yield contributing characters were recorded. Bradyrhizobium inoculation significantly increased number of nodules, nodule weight, root and shoot length, seed and stover yield, yield attributes, nitrogen and protein yield of mungbean compared to non-inoculated control. Bradyrhizobium inoculation in presence of Mo and B recorded the highest nodule number and nodule weight, and also seed and stover yields. Bradyrhizobium inoculation alone or in presence of Mo or B also recorded higher nodulation over other treatment combinations. Bradyrhizobium inoculation was better than nitrogen in almost all the parameters studied. Molybdenum and boron also performed better results. This result indicated that the use of Bradyrhizobium inoculants with molybdenum and boron appeared to be an effective method for successful mungbean production.

SAU sharisha-1&4) YEASMIN, MST. TOUFICA A field experiment was earned out at Sher-e-Bangla Agricultural University Farm, Dhaka during the rabi season of 2010-2011 to evaluate the perfbrmancc of verniicompost and inorganic fertilizers on growth, yield, and oil content of mustard. The treatments used two varieties such as variety-ISAU sharisha-1 & variety2'SAU sharisha-4 and 3 levels of each of vermicomposts viz. F0, 1:1 F2 (0, 1.5, 2.5)t ha4 and inorganic fertilizers (N, P. K, S. Zn, B)viz. F3 1.4 F5 (40-80-120.15-3045,20-40-60,10-20-30.1.2-2.4-3.6,1-2-3) kg ha4.The results demonstrated that high vermicompost (2.5tiha) and medium doses of inorganic fertilizers (80-30-40-20-2.4-2 kgTha) increased seed yield of mustard significantly. Considering the varietals effect the highest seed yield (2.0451 ha') was found in variety-i and lowest seed yield (1.78 hi') was observed in variety-2. The highest number of siliqua (180.617) was obtained from variety-i and on the other hand the lowest number of siliqua (165.792) was obtained from variety-2. Variety-2 showed highest oil content (44.12%) and variety-I give the lowest oil content (43.1%). Effects of fertilizer showed that the highest seed yield (2.314 t haj was found from medium fertilizer (80-30-40-20-2.4-2 kg/ha) and the lowest seed yield (1.63 t had) was obtained from low vermicompost treatment (1.5 t/ha). The highest number of siliqua (189.8) was obtained from medium fertilizer (80-30-40-20-24-2 kg/ba) and on the other hand the lowest number of siliqua (133.5) was obtained from (0 Viva) control treatment. The treatment mediun, fertilizer (80-30-40-20-2.4-2 kg/ha) showed the highest oil content (44.4%) and control treatment give the lowest oil content (43.05%).The interaction effect showed that maximum significant seed yield (2.740t hi1 ) was obtained from variety-I by the application of medium fertilizer (80-30-40-20-2.4-2 kg/ha) but the percentage of oil content (45.2%) was maximum at Variety-2 by the application of medium fertilizer (80-30-40-20-2.4-2 kg/ha). Oil percentage was greater in SAU sharisha-4(hlaek) than that of SAU sharisha-l(white).Thc oil content was not significantly influenced by the difference of treatments.

A. Masuin An experiment was conducted in the laboratory of the Department of Agricultural Chemistry, Sher-e-Bangla Agricultural University (SAU). Dhaka. Bangladesh, during this period from July to December, 2009 to know the impact of 4 selected insecticide (Diazinon 60 EC, Marshal 20 EC, Dursban 20 EC and Admire 200 Si) on soil microorganisms and the impact was expressed as the amount of CO2-C evolution per gram soil and dehydrogenase activity (WV formation). The insecticides were injected in the soil samples and incubation. The data were taken after 2. 4.8.16 and 24 days of incubation for the determination of the microbial activity. The experiment revealed that all the insecticides tested had an effect on microbial activity or microbial population. The result shows that the amount of CO2 is higher in all insecticide treated soils than that of control soil after 2 days of incubation, which indicates the stimulatory effect of all the insecticides on soil microorganisms during this period. Moreover, the high amount of CO? evolution in Marshal 20 EC treated soils indicates a grate activity of soil microorganisms. On the other hand Diazinon 60 EC and Durseban 20 EC showed negative effect on microbial activity till 4 days of incubation: but the microbial activity increased there after. In case of dehydrogenase activity, the insecticide treated soils gave higher formazan yields than that given by controlled soil. Diazinon 60 EC consistently high positive dehydrogenase effect starting right from its application and continued to have, even up to the last days of incubation. Similar but slightly less positive effect was observed in case of Admire 200 SL. Marshal 20 EC and Dursban 20 NC.
