The experiment was carried out with four levels of sulphur application matter weight, number of siliqua plant -1 , number of seeds siliqua -1 , number of seeds plant1, number of branches plant -1 , 1000-seed weight, seed yield plant -1 and biological yield. Maximum seed yield plant -1 was observed with 30 kg S/ha 0 1 2 2 -1 , number of siliqua plant -1 , number of seeds siliqua -1 , number of seeds plant -1 , 1000-seed weight were found to be highest with these three weeding. Plant height as well as dry matter accumulation were also found to be maximum with three weeding.. The increased seed yield plant -1 with three weeding 1 results. The highest seed yield as well as biological yield was found with the interaction of three weeding a n d 30 kg S/ha which was statistically identical with the interaction of two weeding a n d 30 kg S/ha . Maximum number branches plant -1 0 , number of siliqua plant , seeds siliqua and 100-seed weight was also found from the interaction of three weeding a nd 30 kg S/ha. Two weeding combined with 30 kg S/ha produced almost similar result. 3 -1 AThesis Submitted to the Faculty of Agriculture Sher-e-Bangla Agricultural University, Dhaka-1207 in partial fulfilment of the requirements for the degree of MASTEROF SCIENCE IN AGRONOMY 2011-06-01T00:00:00Z http://localhost:8080/handle/123456789/2417 EFFECT OF TRANSPLANTING DATE ON THE GROWTH AND YIELD OF INBRED AND HYBRID RICE VARIETIES IN T.

RAFIQUL The experiment was carried out at the research field of Sher-e-Bangla Agricultural University, Dhaka, during the period from 10 November 2010 to 10 March 2011 to investigate the effect of potassium and sulfur on morpho-physiological characters, yield attributes and yield of potato. The experiment comprised of four different doses of potassium (0, 117, 130, 43 kg ha -1 ) along with sulfur (0, 24, 29 and 34 kg ha ). The experiment was laid out in split plot design with three replications. The growth parameters such as plant height, stems hill -1 , leaves hill -1 -1 , total dry mass (TDM) plant and TDM m -2 , yield attributes such as tubers hill -1 and single tuber weight and tuber yield and marketable yield were significantly influenced by potassium and sulfur. Results revealed that, number of leaves hill -1 , stems hill -1 , plant dry matter content, tuber dry matter content, tubers m -2 , seed yield, marketable yield significantly increased with increasing potassium levels, whereas, plant height decreased with increasing potassium level. On the other hand plant dry matter content, tuber dry matter content, stems hill , tubers m -2 , seed yield, marketable yield increased significantly with increasing sulfur level. While plant height, number of leaves hill -1 and tubers m -2 decreased with increasing sulfur level. Combined effect of potassium and sulfur reveled taht the highest number of tubers m -2 was achieved by 130 kg potassium ha -1 with 34 kg sulfur ha . But 130 kg potassium ha -1 with 29 kg sulfur ha -1 produced more 45-55 mm sized tuber than 130 kg potassium ha -1 with 34 kg sulfur ha -1 . Application of 130 kg potassium ha with 34 kg sulfur ha -1 produces more <28 mm sized tuber than that of 130 kg potassium ha with 34 kg sulfur ha -1 . Finally 130 kg potassium ha -1 with 29 kg sulfur ha -1 produced numerically highest yield but statistically similar with 130 kg potassium ha -1 -1 -1 -1 with 34 kg sulfur ha -1 . -1 -1 A Thesis Submitted to the Faculty of Agriculture Sher-e-Bangla Agricultural University, Dhaka in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE (M.S.)

MIZANUR Four separate pot experiments were carried out on four pulse crops in Rabi season during 2010 to 2011. The experiments were conducted to evaluate the effect of GA lemon juice and tamarind leaf extract on germination and vigour of pulse seed (lentil, chickpea, grasspea and cowpea).The experiments were done with cultivar, BARI Masur- 4, BARI Chola-6, BARI Khesari-2 and BARI Felon-1 with three growth regulators: gibberellin, lemon juice and tamarind leaf extract. During Rabi season 2010 to 2011, three concentrations of gibberellins (10, 20 and 30 ppm ), three concentrations of lemon juice ( 2, 4 and 6 %), three concentrations of tamarind leaf extract (0.05%, 0.1% and 0.15%) with two soaking time duration ; six hours and twelve hours with control. In Rabi seasons, in case of lentil, plant length continued to increase till harvest of young seedlings. Gibberellin(GA 3 ) improve germination percentage of lentil, chickpea, grass pea and cowpea; Seedlings length ,dry matter and germination index of all crops; vigour index of all crops except grass pea, and speed of germination in lentil, chickpea and grass pea. Lemon juice enhanced germination percentage, seedling length, vigour index and germination index in cowpea. Tamarind leaf extract increased the germination percentage in lentil, chickpea, grass pea and cowpea; seedling length in grass pea; vigour index in lentil, chickpea and cowpea; speed of germination in lentil, chickpea and grass 3, pea. In comparison with plant growth regulators, length, weight, was found to be positively correlated and in most cases, relationships were significant.
