| dc.description.abstract | The experiment was conducted at the Agronomy Farm, Sylhet Agricultural University during the period from November 2012 to February 2013 to know the effect of sowing methods (relay and traditional following land preparation) and select suitable variety(s) of pea in the Pea-Fallow-T. Aman rice cropping pattern. There were two sowing methods (i. relay with T. Aman rice and ii. Traditional after harvest of T. Aman rice following land preparation) and four pea varieties (i. BARI motoshuti-1, ii. IPSA motorshuti-1, iii. Jhikorgacha local and iv. Natore local) as treatments in the experiment. The results exhibited that yield and all yield contributing characters except number of seed/pod differed significantly between the two sowing methods. Significantly higher values of plant height, number of pod/plant, 100 seed weight, green pod yield and fodder yield were found in relay cropping system. Higher green pod yield (2872 kg/ha) in relay cropping system was possibly attributed by the higher number of pod/plant and larger seed size. The results also revealed that yield and all yield attributes differed significantly among the varieties. The variety Jhikorgacha local produced the highest mean green pod yield (3030 kg/ha) and it was statistically similar to that of Natore local (3008 kg/ha) might be attributed by the higher plant population per unit area and number of pod/plant mainly. BARI motorshuti-1 produced the lowest green pod yield (1874 kg/ha) possibly because of fewer number of pod/plant and plant population/m2. All the parameters except number of seed/pod and 100-seed weight varied significantly due to interaction of sowing methods and varieties. Statistically at par and significantly highest number of pod was found in IPSA motorshuti-1 and Natore local in relay cropping system. The lowest number of pod/plant was found in BARI motorshuti-1 which was similar to those of others with same traditional sowing method. In general, all varieties gave higher green pod yield in relay cropping corresponding to the yield in traditional sowing method. The highest green pod yield (3333 kg/ha) was obtained from Natore local and this was statistically at par with that of Jhikorgacha local (3234 kg/ha) might be attributed by the higher number of pod/plant as well as plant population/m2 in the relay cropping system. The lowest green pod yield (1745 kg/ha) was obtained from BARI motorshuti-1 under traditional method of sowing. Due to lower number of pod/plant all varieties produced lower green pod yield in spite of higher plant population/m2 in the traditional sowing method. Natore local motorshuti produced the highest fodder yield (4055 kg/ha) under relay cropping system which was significantly different from the others and BARI motoroshuti-1 produced the lowest (2220 kg/ha) under traditional sowing method. The maximum gross return (Tk 1,74,760 /ha) was obtained from the variety Natore local followed by Jhikorgacha local (Tk 1, 69, 218 /ha) in relay cropping system. Similar trends were found in case of gross margin. | en_US |
