| dc.description.abstract | A field exponents entitled "Studios on Important Factors Affecting upland Rice yield Under Rainfod Condition" consisting of eight treatment combinations with four replications laid out in randomized block design trap conducted during the 1988 at Birsa Agricultural University, Kanke, Farm. The results of the aforesaid field experiment exhibited a significant increase in growth attributes of upland rice such as plant height, leaf area Index, crop growth rate and relative growth sate due to application of recommended dose of fertilizer (40 kg N + 30 kg P + 20 kg Ka ha) and effective weed control (Hand weeding at 20 and 40 DAS) over no application of fertilizer and woody chock which also reflected increase in yield attributes (number of panicles per unit area, length of panicle, fallen grain per panicle, percentage of filled grain pos panicle and test-weight) and grain and straw yield. Line Souring also proved a bit beneficial for upland rice cultivation. Timely wooding exhibited the maximum grain yield (13.62 q ha) over woody check (5.53 q ha) followed by application of recommended dose of fertilizer (11.72 q ha) over no application of fertilize (7.42 q ha) and the minimum in broadcast seeding (8.61 q ha) being significantly inferior to line seeding (10.54 q ha). A significant interaction effect between weeding and fertilizer application ( * ) on grain yield was observed recording the maximum yield (16.45 q ha). However, 1ine sowing, application of recommended dose of fertilize and wooding at 20 and 40 days after sowing registered the maximum grain yield (18.60 q ha). Similar trend was observed in respect of stream yield on account of the aforesaid production factors employed in the pro sent investigation. Fertilizer application enhanced weed population and day matter accumulation in weedy check treatment whereas line sowing significantly decreased wood population as compared to broadcast seeding. The man net return (R 165s2,10 ha) with a benefit cost ratio (1.54) was calculated when upland rice was raised in lines (20 cm apart), receiving 40 kg N + 30 kg P + 20 lg k2O per hectare in conjunction with wooding at 20 and 40 days after sowing. Thus, line sowing, application of recommended dose of fertilizes and effective weed control are instrumental factors for improving up and rice productivity | |
