RESPONSE OF MANURE AND GREEN MANURE AS A COMPONENT OF INTEGRATED NUTRIENT MANAGEMENT (INM) IN T. AMAN RICE (BRRI dhan 40) NAHER, MST. SHAMSUN ABSTRACT RESPONSE OF T. AMAN RICE (BRRI dlian 40) TO MANURE AND GREEN MANURE AS A COMPONENT OF INTEGRATED NUTRIENT MANAGEMENT (INM) A (kId experiment was earned out at Sher-e-Bangla Agricultural University (SAt)) Farm during the kharif period from July. 2011 to November 2011 to evaluate the response of BRRI dhan 40 to green manure & cowdung as a component of Integrated Nutrient Management The (kId experiment was conducted in combination with inorganic fertilizer and organic manure, The Red Brown Terrace Soil of Teigoan series was silty loam in texture having pH 5.6 The experiment was conducted in a Randonli7ed Complete Block Design (RCBD) with II treatments and 3 replications. The treatments were 'E'c'( Control), 1, (N 120 P,4K45 S21, Recommended dose), T 2 ( 80% NPKS -1-2 t ha" DH). T 3 ( 80% NPKS +4 t ha' t CD), T4 ( &J% NPKS + I tha 4 DII + 2 t ha CD). T;(70%NPKS t4tlia1 DI-1),T,( 70% NPKS + St ha" CD). T 7 ( 70% NPKS + 2 t ha' 01-I 4 t ha" CD ), T g ( 50% NI'KS 1- Gt ha" DH ), T9 ( 50% NPKS + 12 t ha" CD ), T10 ( 50% NPKS + 3 t ha" DI-! —6 t ha CD ). The result demonstrated that the yield contributing characters, grain and straw yields were significantly infitieneed by the added fertilizers and manure. Application of 70 % NPKS fertilizers -'- 4 c ha" dhaincha produced the highest grain yield ( 5.9 t hi') and the second highest grain yield (5.85 t ha•' was obtained from T 2 ( 80% NPKS + 2 1 ha ' Dli) treatment. In straw yield, the treatment 80% NPKS + 4 t ha' CD) produced the highest yield (8.59 t ha") and the second highest straw yield (8.08 t ha " ) was obtained front 1, (N 12o P1 4 1<4 S20 Recommended dose) treatment. The grain yield increases over control and ranges between. 31.18 to 86.31 %.The treatments 'I', and T 2 resulted in higher nutrient use efficiency along with higher N. P. K and S uptake by the T. Aman rice. The application of inorganic lbrtilizer with manure inlluenced the nutrient concentration in rice grain and straw. The higher grain N, P. K and S concentrations were observed in the treatments where dhaincha and cowdung were applied in combination with NPKS fertilizers. Grain yield of 'I'. Aman rice was positively correlated with number of effective tiller, plant height, panicle length. filled grain per panicle and straw yield. The combined application of fertilizer and organic manure increased the % organic carbon (OC). organic matter (OM) %. total N, available P and available S in post harvest soils. The overall findings of the study indicate that the integrated use of inorganic fertilizer and organic manure should be encouraged to address the deteriorating soil fertility and increased crop yield ofT. Aman rice.

There were three levels of Magnesium viz., 0, 6, 12 kg ha' and three levels of Zinc viz.,0.3,6kgha"in the experiment. The experiment was laid out in a Factorial Randomized Complete Block Design with three replications. Magnesium showed significant effect on yield and yield attributes of wheat. Application of magnesium @ 12 kg ha" produced the highest seed yield, plant height, number of tillers plant", 1000-seed weight and straw yield. In all the cases lower response was found from the control treatment. Zinc fertilizer also had significant effect on yield and yield attributes of wheat. Application of Zinc @ 6 kg ha' gave the highest seed yield, plant height, number of tillers plant", spike length, number of effective spikelets spike",l000-seed weight, straw yield but the lower response was found in all cases from the control treatment. Magnesium in combination with zinc showed significant effect on yield and yield attributes of wheat. Magnesium @ 12 kg ha" and zinc @6 kg ha" resulted the highest seed yield, plant height, and straw yield, number of effective spikelets spike" and 1000-seed weight and lower response was found in the control treatment. The addition of Mg and Zn not only increased the yield but also protect the soil from total exhaustion of nutrients.

EFFECT OF VARIOUS ORGANIC MANURE AND INORGANIC FERTILIZER WITH DIFFERENT WATER MANAGEMENT ON THE GROWTH AND YIELD OF BORO RICE BARI, A. S. M. FAZLE The experiment was conducted in the farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from December 2010 to April 2011 to study the effect of various organic manure and inorganic fertilizer with different water management on the growth and yield of boro rice (BRRI dhan29). The experiment consists of 2 factors i. e. irrigation and fertilizer plus manure. Two levels of irrigations (i= Alternate wetting and drying and 11= Continuous flooding) with 8 levels of fertilizer plus manure, as TO: Control, T1 : 100% N 0gP,5K45S20Zn2 (Recommended dose), T 2: 50% NPKSZn + 5 ton cowdung/ha, 13 : 70% NPKSZn + 3 ton cowdung/ha, T 4: 50% NPKSZn ± 4 ton poultry manure/ha. T 5: 70% NPKSZn + 2.4 ton poultry manure/ha, 1'6: 50% NPKSZn 1- 5 ton composllha and T 7 : 70% NPKSZn + 3 ton compostihs were used in the experiment. There were 16 treatment combinations and 3 replications. Results revealed that irrigation had no significant effect on the yield and yield parameters but a little bit higher yields were obtained from continuous flooding (J). The Yield contributing characters and yields were significantly affected by fertilizer and manure application. The highest effective tillers/hill (13.3), plant height (88.56 cm), panicle length (21.07 cm), 1000 grain wt. (23 g), grain yield (6.96 tiha) and straw yield (6.03 Uha) were found from T 4 (50% NPKSZn + 4 ton poultry manurc/ha) treatment and the lowest in To treatment. The highest grain and straw yields were found by the application of organic manure plus inorganic fertilizers compared to the use of chemical fertilizer alone. Significantly the highest grain (7.13 tlha) and straw yields (6.27 tlha) were recorded from 1 1T4 (Continuous flooding + 50% NPKSZn + 4 ton poultry manurelha) and the lowest (3.84 t/ha) from loTo (Alternate wetting and drying + control) treatment combination and 85% grain yield increased over control. Irrigation did not significantly influence the grain and straw nutrient concentration and uptake while the higher NPKS uptake was recorded in continuous flooding. The boro rice grain and straw nutrient concentrations in grain and straw of boro rice were significantly affected by the application of fertilizer and manure and application of fertilizer plus manure resulted in higher nutrient use efficiency along with higher N, P. K and S uptake by boro rice. The highest concentrations of grain N (0.997%). p (0.292%), K (0.361%), S (0.130%) and straw NPKS were recorded from T treatment and lowest from To treatment. Similarly, nutrient uptake by rice grain and straw was also higher in T 4 treatment compared to other fertilizer treatment. The highest nutrient concentrations and uptake were recorded in 1 1T4 treatment combination. The levels of organic matter and nutrient concentration were increased in the post harvest soils where manure plus inorganic fertilizer were used.
