Mostofa An experiment was conducted at the farm of the Bangladesh Agricultural Development Corporation (BADC), Khadimpara, Sylhet 3100 during the period from August to November, 2014 to see the effect of K, S and Zn application on the performance of BRRI dhan56 regarding to growth, yield and yield contributing characters under the acidic soil in Sylhet region. The experiment consists of eight treatments viz, Control, K80, S12, Zn1.8, K80S12, K80Zn1.8, S12Zn1.8 and K80S12Zn1.8. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Data were taken on plant height, number of tillers hill -1 , panicle length, grains panicle -1 , 1000-grain weight, grain and straw yields. Soil status of pre- and post harvest soil also analyzed to know the status due to KSZn application. Result revealed that all the characters except 1000– grain weight were affected significantly due to application of K, S and Zn where K80S12Zn1.8 produced the highest plant height (100.40 cm), effective tillers hill –1 (8.13), longest panicle (27.87 cm) and grains panicle –1 (146.60). The highest grain, straw and biological yield of 4.38, 6.03 and 10.40 t ha –1 , respectively was also produced from the treatment K80S12Zn1.8. The lowest performance was observed in the control treatment for all characters. The soil analysis showed that the nutrient content in post harvest soils under fertilizer applied soil was higher in comparison to initial soil.

Binamoog-8) in acid soil. The experiment was composed of seven treatments viz. T1= Control (without Rhizobium inocula and fertilizers), T2 = Cowdung (CD), T3 = CD+RI, T4 = NPK, T5 = NPK+RI, T6 = ½(NPK)+RI and T7 = Rhizobium inocula (RI). The experiment was laid out in a randomized complete block design (RCBD) with three replications. The nutrients N, P and K were applied @ 14, 14 and 17.5 kg ha -1 from the sources of urea, TSP and MP, respectively; CD was applied @ 8 t ha -1 and RI was applied @ 45 g kg -1 , as seed inoculant. The data on growth, yield and yield contributing parameters were collected at different intervals of mungbean plant from 30 days after sowing to until final harvest at 15 days interval. The initial and post-harvest soils were collected and analyzed. The treatments had significant effects on all the growth, yield and yield parameters of mungbean at different sampling dates except for the number of flowers plant -1 at 30 DAS, percent sterile pods plant -1 at 75 DAS, number of seeds pod -1 and 1000 seeds weight. Application of cowdung @ 8 t ha -1 showed better performance in respect of the longest root, the highest plant height, number of leaves plant -1 , leaf size (leaf length and breadth), number of branches plant -1 , fresh weight plant -1 , dry weight plant -1 , number of flowers plant -1 at 45 and 60 DAS. The cowdung applied plots had the highest number of pods plant -1 , the lowest percent of sterile pods plant -1 , the highest number of seeds pod -1 (5.44), heavier weight of 1000 seeds (39.31 g), the highest seed (705 kg ha -1 ) and stover (2031 kg ha -1 ) yields. However, application of CD+RI responded better in producing the highest number of nodules plant -1 and effective nodules plant -1 at 30, 45 and 60 DAS. The post-harvest soil analysis showed a slight higher pH and increased other nutrients status in soil due to CD+RI and CD application. ii Mon, 01 Dec 2014 00:00:00 GMT http://localhost:8080/xmlui/handle/123456789/312 2014-12-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/311 EFFECT OF NKS NUTRIENTS ON THE GROWTH AND YIELD OF BRRI dhan29 KIBRIA, GOLAM A field experiment was conducted at the field of Regional Station of Bangladesh Rice Research Institute (BRRI), Habigonj, during the period from December, 2012 to May, 2013 to evaluate the effect of NKS nutrients on the growth and yield of BRRI dhan29. The experiment was conducted in a randomized complete block design (RCBD) with three replications. There were six treatments viz. N85P38K50S9, P38K50S9 (-N), N85P38S9(-K), N85P38K50(-S), P38S9(-NK) and N0P0K0S0 (control). Results indicated that N, K and S alone or in combination significantly affected the growth, yield and yield contributing characters of BRRI dhan29. Number of tillers hill -1 gradually increased with the age of plant up to 90 DAT then slightly decreased at crop maturity. The highest number of tillers hill -1 was observed in N85P38K50S9 and the lowest was in N0P0K0S0. Dry weights of leaves, stems as well as total dry weight of plants were recorded the highest in the treatment N85P38K50S9 and the lowest was in N0P0K0S0. Dry weight of panicles hill -1 was the highest in N85P38K50S9 and the lowest was in P38K50S9(-N). The highest plant height (108.4 cm) was noted in N85P38K50S9 while the lowest (89.8 cm) was in N0P0K0S0. The highest number (12.66) of effective tillers hill -1 was recorded in N85P38K50S9 and the lowest (9.0) was in P38K50S9(-N). The highest (27.0 cm) and lowest (19.83 cm) panicle length were noted in N85P38K50S9 and N0P0K0S0, respectively. Number of grains panicle -1 was recorded the highest (141.2) in N85P38K50S9 and the lowest (119.0) was in N0P0K0S0. Thousand grains weight was the highest (23.77 g) in N85P38K50S9 and the lowest (22.0 g) was in P38K50S9(-N). Grain and straw yields were recorded the highest -1 (8.40 and 10.1 t ha ) in N85P38K50S9 and the lowest (5.5 and 6.5 t ha -1 ) in P38S9(-NK), respectively. Thus the treatment combining NPKS had the best growth and yield performance among the treatments.

Das, Papiya A field experiment was conducted at the field of Soil Resource Development Institute (SRDI), Sylhet during the period from October 2012 to March 2013 with a view to evaluate the effect of different rates of lime application on soil nutrients and tuber yield of potato. The experiment consisted of four treatments viz. no lime application (control), 0.988 t lime ha¹, 1.976 t lime ha and 2.904 t lime ha. Liming was done with dolomitic limestone (CaCO3.MgCO3). The experiment was laid out in a randomized complete block design with four replications. Yield and yield components of potato were recorded. The pre- and post- harvest soils were analyzed for pH, total N, exchangeable K, available P. S. Ca and Mg contents. The resuns indicated that liming had significant influence on yield of potato tuber. The days required for 80% emergence, foliage coverage, plant height, root length, number of tubers hill, weight of tubers hill and yield of tuber (t ha") were the highest when lime was added at 0.988 t ha. The highest yield of tuber was recorded 19,09 t ha due to application of 0.988 t lime ha and the lowest yield was found 14.38 t ha' in control treatment. Pre- and post-harvest soils analyses indicated that the application of different rates of lime to soil progressively increased soil pH and increased total N, availability of P. S. Ca and Mg in soils. The exchangeable K tended to decrease with increasing level of lime application. Sun, 01 Dec 2013 00:00:00 GMT http://localhost:8080/xmlui/handle/123456789/163 2013-12-01T00:00:00Z
