YASMIN An experiment was conducted on the performance of wheat (W) - grasspea (G) mixed cropping under different seed rate ratios (% of the recommended seed rates of W and G respectively ; W100, G100, W90 + G10, W80 + G20, W70 + G30, W60 + G40, W50 +G50, W40 + G60, W30 + G70, W20+G80, W10 + G90 and W100 + G100) at 5 the Agronomy field, Sher-e-Bangla Agricultural University, Dhaka-1207, during the period from November 2006 to March 2007. The experiment was laid out in a randomized complete block design with 3 replications. The result showed that highest grain yield of wheat and grasspea were obtained from the respective sole crop. Among the mixed cropping treatments, wheat yield was maximum with seeding ratio of W90G10 closely followed by W80G20 but yield was slightly reduced (2%). Grasspea yield was also highest from sole crop but the yield was reduced considerably from 29 to 93% due to mixed cropping. But mixed cropping treatments gave encouraging results in terms of crop productivity, monetary and land equivalent ratio (LER). The highest LER (1.17), wheat equivalent yield (3.48 t ha -1), combined yield (3.33 t ha-1), gross return (Tk. 88620 ha-1), net return (Tk. 46270 ha-1), benefit- cost ratio (2.09) and monetary advantages (Tk. 12685.94 ha-1) were obtained from seed rate ratio of W70 + G30.

BARI mash-3 (Vigna mungo L.) cv. BARI mash-3 during the period from March 2006 to May 2006. The trial comprised of ten treatments such as T1= No fertilizer and no irrigation (control), T2 = 20 kg N ha-1 as basal, T3 = 20 kg N ha-1 as basal with one irrigation at first flowering stage, T4 = 30 kg N ha-1 as basal, T5 = 30 kg N ha-1 as basal with one irrigation at first flowering stage, T6 = 40 kg N ha-1 as basal, T7 = 40 kg N ha-1 as basal with one irrigation at first flowering stage, T8 = 10 kg N ha-1 as basal and split 10 kg N ha-1 with one irrigation at first flowering stage, T9 = 15 kg N ha-1 as basal and split 15 kg N ha-1 with one irrigation at first flowering stage and T10 = 20 kg N ha-1 as basal and split 20 kg N ha-1 with one irrigation at first flowering stage. Result revealed that nitrogen and irrigation influenced significantly on most of the growth, yield parameters and yield of blackgram. Plant height, number of branches per plant, number of leaves per plant, seeds per pod, leaf dry weight and stem dry weight increased significantly with 40 kg N ha-1 as basal with one irrigation at first flowering stage (35 DAS).This greater dry matter eventually supported the plant to produce more number of branches and pods per plant, which resulted in maximum seed yield per plant (10.45 g) or per hectare (1.86 ton). A functional positive relationship was observed among number of branches per plant, 1000-seed weight, pods per plant, and seeds per pod with seed yield the Faculty of Agriculture, Sher-e-Bangla Agricultural University, Dhaka, In partial fulfilment of the requirements For the degree of MASTER OF SCIENCE IN AGRONOMY SEMESTER: JANUARY-JUNE, 2007 2007-06-01T00:00:00Z http://localhost:8080/handle/123456789/1409 EFFECT OF IRRIGATION AND VARIETIES ON THE GROWTH AND YIELD OF RAPESEED SULTANA, SADIA The study was curled out at the Slier-c- Bangla Agricultural University farm, Dhaka during ?'ovember 2006 to March 2007 to evaluate the effect of irrigation and variety on growth. yield attributes and yield of rapesced. The treatment comprised of three levels of irrigation viz, no irrigation, one irrigation at 20 DAS, one irrigation at 35 DAS, two irrigations at 20 and 35 DAS, and three irrigations at 20, 35 50 DAS, and three varieties viz. SAU Sarisha- I, Kalyania and Improved Tori-7. The experiment was laid out in it split plot design with three replications. Three irrigations (at 20, 35 and 50 DAS) increased economic yield with higher values of harvest index as the yield attributes like branches plant", siliqua plani', seeds siliqua" and 1000 seed weigh were higher The seed yield with three irrigations were 11I.93% and 10.73% higher than no irrigation and two irrigations, respectively.'The variety SAU Sarisha- 1 showed its superiority by producing 1.4 % and 45.94 % higher yield than Kalyania and Improved Tori-7, respectively. This variety (SAU Sarisha-L) also showed higher branches plant", seeds siliqua", 1000 seed weight, biological yield and harvest index. most of the eases interaction of three irrigations with SAU Sarisha- I performed best in respect of grain yield as well as other studied parameters. The highest seed yield (1827.0 kg ha") was found in the interaction of three irrigation with SAU Sarisha- I. This was achieved due to the maximum number of branches plant', seeds siliquae" and 1000 seed weight in this interaction. The yield attributes was also supported with appreciable production of dry matter.
