Abstract
A field experiment was conducted at Jammu during 2008–2009 and 2009–2010 to evaluate the effect of two establishment methods (conventional sowing and zero tillage) in wheat (Triticum aestivum) and four establishment methods (conventional transplanting of 25 days seedling, dry seeding @ 40 Kg/ha, wet seeding after puddling @ 40 kg/ha and SRI methods) and 4 sowing schedules (15th May, 25th May, 5th June and 15th June) in rice (Oryza sativa) under rice-wheat cropping system. Rice establishment methods and sowing schedules had significant impact on growth, yield attributes and yield of rice. Both the direct seeded methods of rice, being at par, recorded significantly higher mean grain yield and other growth parameters of rice as compared to conventional transplanting or SRI method. Similarly, 15th June rice sowing schedule resulted in marked increased in all the growth parameters, yield attributes and grain yield of rice as compared with other sowing schedules. However, both the establishment methods of wheat failed to cause any significant effect on growth and yield of succeeding wheat crop. Establishment methods of wheat and rice as well as sowing schedules of hybrid rice did not cause marked effect on soil physico-chemical parameters as well as available nutrient (N, P and K) content after completion of rice-wheat cycle. However, bulk density of soil at 0–15 and 15–30 cm depths was observed considerably higher with zero tilled wheat, while the minimum in system of rice intensification (SRI) method. Higher net returns and benefit cost ratio were recorded when wheat was established through zero tillage and rice through wet seeded sown on 15th of June in rice-wheat cropping system.
