EFFECT OF NITROGEN AND SULPHUR ON GROWTH AND YIELD OF MUSTARD (SAU SHARISHA-1) MOHIUDDIN, MOHAMMED An experiment was conducted in the experimental field of Sher-e-Bangla Agricultural University, Dhaka to determine the effect of different levels of nitrogen and sulphur on yield and yield contributing characters of mustard as well as the nutrient content and their uptake by mustard plants. The experiment consisted of four levels of nitrogen i.e. 0 kg N/ha (N0), 40 kg N/ha (N1), 80 kg N/ha (N2) and 120 kg N/ha (N3); and four levels of sulphur i.e, 0 kg S/ha (S0), 8 kg S/ha (S1), 16 kg S/ha (S2) and 24 kg S/ha (S3). The experiment was laid out in the two factors Randomized Complete Block Design (RCBD) with three replications. The plant height, the number of branches per plant, the number of siliqua per plant, seed and shoot yield increased with increasing N level upto 80 kg N/ha. Further increasing in N level i.e., 120 kg N/ha had a negative effect on seed yield. On the other hand, with increasing S levels from 0 to 24 kg S/ha, plant height, siliqua per plant, 1000 seed weight, siliqua per plant, 1000 seed weight increased significantly upto 16 S/ha. However the number of branches per plant and seed yield increased upto the highest dose of S (24 kg S/ha). In general N and P content in seed yield increased significantly with increasing N levels upto 80 kg N/ha. However, N content and S content in seed increased with increasing S levels upto 16 kg S/ha and 24 kg S/ha, respectively. Uptake of N, P, K and S by plant increased significantly upto 80 kg N/ha (N2) and 16 kg S/ha (S2). The application of N fertilizers had a negative effect % on total N, available S, available P and available K content in soil while the application of S fertilizer upto 16 kg S/ha showed a significant positive effect on available S status of soil. Considering the combined effect of N and S, the treatment combination N2S3 produced the maximum seed yield (1738 kg/ha).

EFFECT OF PHOSPHORUS, MOLYBDENUM AND Rhizobium INOCULATION ON THE GROWTH AND YIELD OF MUNGBEAN BHUIYAN, MD. MOKTER HOSSAIN A pot experiment was conducted, during kharifl 2005 at the Soil Science Division, Bangladesh Agricultural Research Institute to study the effect of phosphorus, molybdenum and Rhizobium inoculation on the nodulation, growth, yield and yield contributing characters of mungbean (Vigna radiata) on a s i l ty clay loam soil . The experiment was laid out in randomized complete block design with four replications . Ten treatments including 8 treatment combinations of 4 levels of P (0, 20, 40. 60 kg/ha) and 2 levels of Mo (1.0, 1.5 kg/ha) having a common Rhizobium inoculant. One control with no Rhizobium or fertilization and a Rhizobium inoculation only were applied. The performance of Rhizobium inoculant alone was superior to control in almost al l parameters of the crop studied. The maximum Stover and grain yield (about 14.6 g/plant ) was obtained when plants were fertilized with phosphorus (40 kg/ha) , molybdenum (1.0 kg/ha) and Rhizobium inoculation. Rhizobium inoculation along with phosphorus and molybdenum significantly increased the growth of plants, number of nodules, and dry matter product ion as well as grain yield of mungbean significantly compared to inoculated control. Nodular ion (nodule number /plant) was the highest with 20 kg P/ha and 1.0 kg Mo/ha. However , phosphorus and molybdenum application at the rate of 40 kg P/ha and 1.0 kg Mo/ha progressively and significantly increased dry matter content of shoot and root , yield and yield contributing characters of mungbean. Higher dose of phosphorus (60 kg P/ha) and molybdenum (1.5 kg Mo/ha) decreased grain yield and other parameters. Dry weight of plant tops, seed yield/plant and yield -cont. ributing character s were positively correlated with the number of nodules /plant. From this point of view, dry matter product ion, nutrient uptake, yield and yield at tributes of mungbean combined application of Rhizobium inoculant with 40 kg P/ha and 1.0 kg Mo/ha was considered to be the balanced and sui table combination of fertilizer nutrients for achieving the maximum output through cultivation of mungbean in siltyclay loam soil .

DIRECT AND RESIDUAL EFFECTS OF PHOSPHATE ROCK ON SOIL NUTRIENT STATUS AND CROP PRODUCTIVITY IN RICE-RICE CROPPING SEQUENCE FIRDOUSI, JANNATUL Two field experiments were conducted in the same plot in rice-rice cropping sequence during 2005 at sher-e-Bangla Agricultural University farm under Madhupur tract (AEZ-28), to study the direct and residual effects of rock phosphate (PR) as compared to TSP on growth, yield and nutrient uptake of Boro rice (BR-29) as first crop and T.aman (BR-30) as residual crop. The experiments were laid out in a Randomized Complete Block Design (RCBD) with five treatments and four replications of each treatment. The treatments used were Tr control (0 kg P ha'1), T2-PR (35 kg P ha'1), T3-TSP (35 kg P ha1), T4-PR (210 kg P ha'1, applied in the previous crop in 2004) and T5-TSP (17.5 kg P ha'1) + PR (17.5 kg P ha'1). The blanket application of recommended doses of N, P, K, S, and Zn was done in all the treatments. In case the first crop, application of full dose of P (35 kg P ha'1) as TSP (T3) and 1:1 mixture of TSP (17.5 kg P ha'1) and PR (17.5 kg P ha'1) (T5) increased dry matter production at panicle initiation stage, grain and straw yield at the harvest over the control. The highest grain yield (6.8 t ha1) and straw yield (7.47 t ha'1) were obtained in the treatment T5 where a judicious mixture of PR and TSP was used. Application of full does of P as PR and 210 kg P applied in the previous crop had no significant effects on yield of rice. The grain yield due to different treatment ranked in the order of T5 > T3 > T2 > T4 > T|. In general these treatments (T3 and T5) increased effective tiller hill'1, filled grains panicle'1 and N, P, K. and S uptake significantly. In case of residual crop, the treatment T3 and T5 had a significant residual effect regarding grain yield and P uptake. The residual effect of the treatment T5 produced the highest grain yield (4.5 t ha'1). After the harvest of two crops in all P treatments, the soil contained significantly higher amount of organic matter, available sulpher. available P and exchangeable K as compared to the control. The treatments had no significant effect on soil PH and total nitrogen content REGISTRATION NO. 25270/00376 A Thesis Submitted to the Department of Soil Science Sher-e-Bangla Agricultural University, Dhaka in partial fulfilment of the requirements for the degree of MASTER OF SCIENCE (M.S.)

EFFECT OF NPK AND S FERTILIZER ON GROWTH AND YIELD OF WHITE JUTE ADVANCED LINE BJC-370 HOSSAIN, ABU TAHER MOZAMMEL A field experiment was carried out in Young Brahrnaputra and Jamuna Floodplain (AEZ-8) at research field in Central Research Station, Manikganj under Bangladesh Jute Research Institute, to study the effect of NPK and S fertilizer on growth and yield of white Jute I3JC-370. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications- The treatments used were T 1 control (0 kg NPK & S ha'). '12 (45,5,30, 10 kg ha" NPK & S respectively), T 3 (45. 10. 60, 20 kg had NPK & S respectively), T4 (45, 15, 90, 30 kg had NPK & S respectively), 15 (90. 5, 30, 10 kg ha 1 NPK & S respectively), T (90, 10, 60, 20 kg ha 1 NPK & S respectively), T7 (90, 15. 90, 30 kg ha" NPK & S respectively), T 5 (135, 5. 30, 10kg ha" NPK & S respectively), T9 (135, 10, 60, 20 kg had NPK & S respectively) and T o (135. 15, 90, 300 kg ha1 NPK & S respectively). The results indicated that the fibre yield, stick yield, green weight with leaves, plant height (PFI) and base diameter (13D) were found statistically significant. The highest plant height (3.44 m) and base diameter (10.22 mm) were recorded in the plants treated with TI) and T5 treatment respectively at 120 DAS. The highest fibre yield (3.70 t ha"), stick yield (8.14 t ha") and green weight with leaves (62.45 t/ha) was found in treatment '1's and the lowest fibre, stick and green weight with leaves yield were found in control treatment. Dry matter production of root, bark, stick and leaves at different stage were significantly varied with different treatments except 30 DAS. The yields of fibre due to ditThrent treatments ranked in the order ofT 3> T 10> To> 'lo> 1 4>17> T5> T,> T> 'I',. The N, P, K and S contents as well as their uptake by jute plants were also increased due to application of different treatments. The treatments had no significant effect on soil properties like soil pH, organic carbon, total N, available P, exchangeable K and available S. The economic analysis demonstrated that the highest net benefit of Tk. 78444 ha" was obtained in T8 treatment. A Thesis Submitted to the Faculty of Agriculture.
