Abstract: |
Unavailability of suitable variety to cropping pattern such as Maize-soybean-toria /other winter crops has been realized in the recent years. Released varieties have more or less smaller seed size and longer maturity period (135-145 days), which the farmers usually don't prefer. In the present context soybean is getting popularity due to the sharp demands for poultry fanning in the country. Since it is an important component of the poultry feed, in connection with above background soybean genotypes collected from diversified sources were evaluated in observation screening nursery (OBN) and multi-location trial for yield potential, insect-disease reaction in the research station of Rampur and Nawalpur during 2004 to 2005. Multi-location trial was carried out in RCB desjgn with four replications and OBN in rod row. No of rows of the genotypes were two in OBN, four in multi-location trial. Some lines AGS124 (2719 kglha), SB0065 (2589 kglha), Gl873 (2482 kglha) arid LS7716-l6 (2371 kglha) were selected from observation screening nursery based on the over years performances and will be promoted in multi location trial in next season. Similarly, the genotypes Puja (1699kglha), TGX-311-230 (1691 kg/ha) and PK-327 (1614 kglha) were found outstanding in performances than the standard check cobb (1367 kglha) and significant differences among the genotypes over the year and across location in multi location trial. Therefore, these lines will be evaluated in farmer's participatory trial. Participatory research is the spirit of the time for dynamic and effectively adaptation to the farmers root level. Maintaining biodiversity, selection of lines according to farmer and user's choice, farmer-to-farmer seed diffusion lead to fast adoption and rapid impact at farm level (Sarker et al.2003). In the brightness, farmers preferred Puja for it's earlier maturity (125 days), resistant to yellow mosaic virus and bacterial pustule, higher yield (yield potential 2.5 tlha), medium bold seed size (13.83g/100 seed) and adjust well in maize based system either in mono or intercrops.lt is also well adapted from terai/inner terai to mid hills environment. National Seed Board has released it for general cultivation. |
