EFFECT OF INTEGRATED NUTRIENT MANAGEMENT ON THE GROWFH AND YIELD OF BRRI DHAN 29 ISLAM, MOHAMMAD KABIRUL A field experiment was conducted to assess the effect of integrated nutrient management on the growth and yield of BRRldhan29 at the research farm of Sher-e-Bangla Agricultural University, Dhaka-1207 during Boro season 2011-12. T 5 treatment produce the maximum grain yield of 13RRldhan29 due to the application of 100 kg N from urea along with 40 kg N/ha from cowdung. But the effect of cowdung along with nitrogenous fertilizer was the most pronounced than that of vermicompost or nitrogenous fertilizer alone. Similar effects were also observed on N. P. K content and their uptake by BRRI dhan29. The effect of 100 kg N from urea along with 40 kg N/ha from cowdung was statistically identical to treatments 140 kg N/ha from urea, 100 kg N from urea along with 20 kg N from cowdung and 20 kg N/ha as the source of vermicompost, 80 kg N from urea with the combiantion of 60 kg N/ha from cowdung, 80 kg N from urea with the combinaion of 60 kg N/ha as the source of vermicompost and 80 kg N from urea with the association of 30 kg N from cowdung along with 30 kg N/ha from vermicompost. In post harvest soils, the contents of organic matter, total nitrogen, available phosphonis and exchangeable potassium increased due to application of cowdung and vermicompost compared to initial soil. In the contrary, soil pH value decreased slightly as compared to that of initial soil. Application of urea-nitrogen alone slightly decreased the organic matter. The overall results indicate that 100 kg N from urea along with 40 kg N/ha as the source of cowdung was the best treatment in producing higher rice yield with sustenance of soil fertility.

EFFECT OF FERTILIZER, MANURE AND IRRIGATION MANAGEMENT ON THE GROWTH, YIELD AND NUTRIENT ACCUMULATION IN T. AMAN RICE AHMED, ATIK The experiment was conducted in the farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from July 2012 to November 2012 to study the effect of various organic manure and inorganic fertilizer with difibrent water management on the growth and yield of T-Aman rice. I3RRI dhan 32 was used as the test crop in this experiment. The experiment consists of 2 factors i.e. irrigation and fertilizer plus manure. Two levels of irrigations (11 = Continuous flooding and lz= Alternate wetting and drying) were used with 8 levels of fertilizer plus manure, as T O: Control, Ti 100% N1 P 5K45S20Zn2 (Recommended dose), 12: 50% NPKSZn + 5 ton cowdung/ha, Tj: 70% NPKSZn + 3 ton cowdung/ha, T 4: 50% NPKSZn + 5 ton compostiha, T: 70% NPKSZn + 3 ton compost/ha, T: 50% NPKSZn + 3.5 ton poultry manure/ha and 17 : 70% NPKSZn 4 2.1 ton poultry manure/ha, with 16 treatment combinations and 3 replications. At the harvest, the yield parameters and yields were recorded; the irrigation had no significant single effect on the yield and yield parameters. The yield contributing characters and yield were significantly affected by fertilizer and manure and the highest effective tillers/hill (9.13), plant height (119.79 cm), panicle length (27.96 cm), 1000 grain wt. (21.67 g), grain yield (5.12 tlha) and straw yield (10.1 tiha) were found from T2 ( 50% NPKSZn + 5 ton cowdung/ha). T3 (70% NPKSZn + 3 ton cowdung/ha), T (70% NPKSZn + 3 ton compostiha), 1'4 (50% NPKSZn + 5 ton eompostJha), 17 (70% NPKSZn ± 2.1 ton poultry manure/ha) and T (100% N 1®Pi SICISSNZn2) treatment respectively and lowest in T( p treatment. The highest percent (38.3%) grain yield increase was obtained from 17 treatment. The higher grain yields were found by the application of organic plus inorganic fertilizers compared to the use of chemical fertilizer alone. The yield parameters were significantly influenced by combined application of irrigation and fertilizer and the highest grain yields (5.78 t/ha) were recorded from lj1 (Alternate wetting and drying + 70% NPKSZn 4- 2.1 ton poultry manure/ha) and lowest (3.42 tilia) from 121"o (Alternate wetting and drying + control treatment) treatment combination and 69% grain yield increased over control. The 1Aman rice grain and straw nutrient concentrations were sigiiificantly affected by the application of fertilizer and manure. The higher N,P,K & S concentrations and uptake were observed in the treatments where fertilizer plus manure were applied. The highest concentrations of grains N (1.295%), p (0.265%). K (0.282%) and S (0.204%) were recorded from T6. 1 3, [ j and T7 treatment respectively and lowest from T o treatment. Similarly, higher levels of N. P. K and S were uptaken by grain at 1' 4, T3. T6 and 17 treatment respectively compared to other fertilizer treatment. A Thesis Submitted to the Faculty of Agriculture, Sher-e-Bangla Agricultural University, Dhaka.
