Abstract:
Rice is major crop in kharif season on northern part of country. Crop geometry and nitrogen management is the key factor for rice cultivation and it response better when hybrid rice were grown with appropriate management practices. Keeping these things in mind, on-farm trials were undertaken on farmer’s field in participatory manners to workout best crop geometry and suitable nitrogen dose for higher production of hybrid rice under partially reclaimed sodic soil condition during kharif 2010 and 2011. Trials were conducted in five villages of the district with 06 treatments, comprising 03 crop geometry (15X15cm, 20X10cm and 20X15cm) and 03 nitrogen levels (100, 120 & 150 kg N/ha) in a farmers’ participatory mode. All the growth and yield attributing characters were maximum with wider crop geometry of 20X15cm and minimum with closer crop geometry of 15X15cm, however, the grain yield showed non-significant difference. The growth, yield attributes, grains and straw yields were increased significantly with increased levels of nitrogen during both years. The highest gross return of Rs. 87,228 per ha was recorded with 150 Kg N/ha in conjunction with crop geometry of 20X10cm followed by the spacing of 20X15cm alongwith 150 kg N/ha. Crop should be transplanted at closer crop geometry of 20X10cm and fertilized with same amount of nitrogen (ie 150 kg /ha) those recommended for neutral soils.
