S. A field experiment was conducted to evaluate the response of Cowdung and Urea on rice under wetland condition at the research farm of Sher–e–Bangla Agricultural University, Dhaka, Bangladesh during the Boro season (Mid November–March) of 2012–13. Two rice varieties namely BRRI dhan29 (V1) and Heera 4 (V2) and seven treatments including control viz. T0: controlled or no fertilizer, T1: 0 t ha–1 Cowdung (0% N) + 280 kg ha–1 Urea (100 % N as Urea), T2 = 1.28 t ha–1 Cowdung (10% N as CD) + 252 kg ha–1 Urea (90%N as Urea), T3 = 2.56 t ha–1 Cowdung (20% N as CD) + 224 kg ha–1 Urea (80%N as Urea), T4 = 3.84 t ha–1 Cowdung (30% N as CD) + 196 kg ha–1 Urea (70%N as Urea), T5 = 5.12 t ha–1 Cowdung (40 % N as CD) + 168 kg ha–1 Urea (60%N as Urea) and T6 = 6.40 t ha–1 Cowdung (50 % N as CD) + 140 kg ha–1 Urea (50%N as Urea) were used for the present study. The experiment was laid out in RCBD method with three replications and analysis was done by the MSTAT–C package program and means were adjudged by DMRT at 5% level of probability. Effect of variety was significantly affected the whole characters of the study except harvest index and K content in postharvest soil where the HYV variety Heera 4 had highly significant than BRRI dhan29. Similarly, whole studied traits of the study were also influenced significantly due to the effect of cowdung + Urea as a source of N where the treatment T4 (3.84 t ha–1 cowdung + 196.0 kg ha–1 Urea) showed understanding superiority for getting the better growth, higher yield and greater significant effect on nutrient management practices. Most of the studied traits were also influenced significantly due to the effect of interaction of variety and cowdung + Urea fertilizer where harvest index, P and K content in grain and N and P content in straw showed numerically similar performance among the interaction treatments due to non significant variation. Rest of the characters had highest in variety Heera 4 receiving of 3.84 ton cowdung ha–1 + 196.0 kg Urea ha–1 (V2T4) as well as the tallest plant (101.40 cm), more effective tillers hill–1 (23.90), longest panicle (33.14 cm), more grains panicle–1 (219.30), highest 1000–grain weight (33.10 g), highest yield of grain, straw and biological (6.53, 7.96 and 14.49 t ha–1) were recorded. Only N content in grain had highest (1.190%) in Heera 4 receiving of 5.12 ton cowdung ha–1 + 168.0 kg Urea ha–1 (V2T5) while K content in straw had highest (1.475%) in Heera 4 treated by T4 (V2T4). NPK uptake in grain (75.38, 21.73 and 20.97 kg ha–1, respectively) and straw (59.28, 14.66 and 117.50 kg ha–1, respectively) were found in V2T4 while same treatment also recorded the highest NPK content in postharvest soil (0.0960 ppm, 34.70 ppm and 0.0467 meq 100 g–1, respectively). The overall results indicate that the variety Heera 4 and 3.84 ton cowdung ha–1 (30%) along with 196.0 kg Urea ha–1 (70%) as singly or their interaction was the most selective variety and optimum Nitrogen levels for getting the superior yield under wetland condition and higher capability to increase nutrient ability in grain and straw as well as increase the sustenance capacity of the soil. The above results also indicated that the organic fertilizer as cowdung can be reduced 30% use of inorganic fertilizer which also reduced the soil pollution by chemical fertilizer.

The highest oil content (21.52%) was observed from S 2 0 2 and the lowest (16.78%) from S .The maximum concentration in seed for N (2.80%), P (0.407%), K (0.574%), S (0.327%) and Mo (0.0143%) was found from S , while the minimum concentration in seed for N (1.67%), P (0.350%), K (0.447%), S (0.268%) and Mo (0.0112%) from S 0 2 . In case of molybdenum, the highest seed yield (1.93 t ha ) was recorded from Mo 2 , whereas the lowest yield (1.70 ha -1 ) from Mo . The highest oil content (20.64%) was recorded from Mo , whereas the lowest oil content (18.21%) from Mo 0 2 . The maximum concentration in seed for N (2.61%), P (0.402%), K (0.550%), S (0.316%) and Mo (0.0138%) was observed from Mo (1.5 kg Mo ha -1 ) and the minimum concentration in seed for N (2.18%), P (0.349%), K (0.485%), S (0.286%) and Mo (0.0121%) was recorded from Mo . For the interaction effect of sulphur and molybdenum, the highest seeds yield (2.21 t ha -1 ) was found from S 2 Mo 2 , while the lowest seeds yield (1.56 t ha ) from S 0 Mo 0 . The highest oil content (23.57%) was found from S 2 Mo , while the lowest (16.25%) from S 0 Mo 0 2 . The maximum concentration in seed for N (0.261%), P (0.402%), K (0.550%), S (0.316%) and Mo (0.0138%) was observed from S , whereas the minimum for N (1.52%), P (0.334%), K (0.433%), S (0.261%) and Mo (0.0108%) from S 0 Mo 0 . It may be concluded that application of 20 kg S ha & 1.5 kg Mo ha -1 can be more beneficial for the farmers to get maximum yield. -1 0 1 0 2 -1 Mo 2 0 2 -1 A Thesis Submitted to the Faculty of Agriculture Sher-e-Bangla Agricultural University, Dhaka in partial fulfilment of the requirements for the degree of MASTER OF SCIENCE (MS) IN SOIL SCIENCE SEMESTER: JANUARY-JUNE, 2014 2014-06-01T00:00:00Z http://localhost:8080/handle/123456789/2950 INFLUENCE OF SULPHUR AND ZINC ON THE YIELD OF T. AMAN RICE (BRRI dhan34) SHARMIN, MASHUKA The experiment was conducted in the Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from June to November 2013 to find out the influence of sulphur and zinc on yield of transplanted (T.) aman rice. BRRI dhan34 was used as the test crop in this experiment. The experiment consisted of two factors. Factor A: 3 levels of sulphur (S 0 : 0 kg S ha -1 , S 1 : 8.0 kg S ha -1 , S 2 : 12.0 kg S ha ) and Factor B: 4 levels of zinc (Zn 0 : 0 kg Zn ha -1 , Zn 1 : 1.0 kg Zn ha -1 , Zn , Zn 3 : 3.0 kg Zn ha -1 2 -1 : 2.0 kg Zn ha ). The experiment was laid out in a randomized complete block design (RCBD) with three replications.

AMAN RICE BOSAK, RAJIB CHANDRA The experiment was conducted in the farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from July 2013 to November 2013 to study the effect of various organic manure and inorganic fertilizer with different water management on the growth and yield of T. Aman rice. BRRI 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 (I =Continuous flooding and I 2 1 =Saturated condition) were used with 8 levels of fertilizer & manure, as T : Control, T 1 : 100% N 120 P 25 K 60 S 20 Zn 2 (Recommended dose), T : 50% NPKSZn + 5 ton cowdung/ha, T 3 : 70% NPKSZn + 3 ton cowdung/ha, T 2 : 50% NPKSZn + 5 ton compost/ha, T 5 : 70% NPKSZn + 3 ton compost/ha, T 6 4 : 50% NPKSZn + 3.5 ton poultry manure/ha and T : 70% NPKSZn + 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 (10.00), plant height (112.73 cm), panicle length (23.82 cm), no. of filled grains/panicle (94.20), 1000 grain wt. (21.90 g), grain yield (4.70 t/ha) and straw yield (6.58 t/ha) were found from T 7 (70% NPKSZn + 3 ton compost/ha), T 1 (100% Recommended Dose; N 120 P 25 5 K 60 S 20 Zn (100% Recommended Dose), T 1 (100% Recommended Dose), T (50% NPKSZn + 3.5 ton poultry manure/ha), T 4 (50% NPKSZn + 5 ton compost/ha) and T 6 (50% NPKSZn + 3.5 ton poultry manure/ha) treatments, respectively. The higher grain yield was found by the 6 application of organic plus inorganic fertilizers compared to the use of chemical fertilizer alone. The yields were influenced by combined application of irrigation and fertilizer and the highest grain yields (4.87 t/ha) was recorded from I 2 T (Saturated condition + 50% NPKSZn + 5 ton compost/ha) which was similar to the yield of I 4 1 T treatment combinations. The lowest grain yields (3.07 t/ha) was recorded from I 6 , I 1 (Continuous flooding + control) treatment combination. The higher concentrations of pore-water P & K were observed in the treatments where organic plus inorganic fertilizers were used combindly. The grain yield and nutrient concentrations were positively correlated with the pore-water P & K concentrations.
