0761 Efficacy of Different Crop Establishment Methods on Yield and Economics of Rice (Oryza sativa L.) in Sandy and Loam Soils of Jammu Region

  1. 1. EFFICACY OF DIFFERENT CROP ESTABLISHMENT METHODS ON YIELD AND ECONOMICS OF RICE ( Oryza sativa L.) IN SANDY LOAM SOILS OF JAMMU REGION Saha Anuradha 1 and Bharti Vijay 2 1 Jr. Scientist (Agronomy), AICRIP on Rice, and 2 Jr. Scientist (Agronomy), WMRC, Sher-e-Kashmir University of Agricultural Sciences and Technology-Jammu, Chatha, Jammu, India
  2. 2. INTRODUCTION * Decreasing availability of water for rice * Uncertainty in water supply due to unequal distribution of rainfall or failure of monsoons. * Decreasing soil health as well as declining sustainability of rice production systems. * Need for water saving and for economically beneficial and sustainable technology Recognizing these problems, experiments were conducted during kharif 2005 and 2006
  3. 3. OBJECTIVES <ul><li>To evaluate different crop establishment methods which can help in water saving. </li></ul><ul><li>To evaluate the methods in terms ofwhich has consequent effect on growth, yield and economics of rice. </li></ul>
  4. 4. MATERIAL AND METHODS <ul><li>Design : RBD Replications : 4 </li></ul><ul><li>Cultivar : PC-19 (Local high-yield variety) </li></ul><ul><li>Soil : Sandy loam with pH of 7.14 </li></ul><ul><li>Treatments </li></ul><ul><li>1. Normal Transplanting (NT) @ 30 days, 3 seedlings / hill </li></ul><ul><li>2. System of Rice Intensification (SRI) : TP @ 12 days, single seedling </li></ul><ul><li>3. Integrated Crop Mgmt (ICM) : TP @ 18 days, 2 seedlings </li></ul><ul><li>4. Drum Seeding </li></ul><ul><li>5. Line Sowing </li></ul><ul><li>6. Broadcasting </li></ul><ul><li>All methods except for SRI and ICM maintained 5±2cm of stagnant water up to 15 days before harvesting </li></ul><ul><li>With SRI, saturated condition until panicle initiation was maintained </li></ul><ul><li>With ICM, alternate wetting and drying condition was practised </li></ul>
  5. 5. RESULTS <ul><li>SRI showed the highest yield attributes. </li></ul><ul><li>Highest grain yield was obtained with SRI, followed by NT and ICM. </li></ul><ul><li>Maximum water use efficiency was showed by SRI method </li></ul><ul><li>NT used 21.27 and 10.50 per cent more water compared to SRI in both years. </li></ul><ul><li>Maximum net returns and highest benefit:cost ratio were obtained from SRI. </li></ul><ul><li>CONCLUSION </li></ul><ul><li>Although SRI requires more skill for transplanting and weed management, it reduces water requirement as well as lowers cost of production. </li></ul><ul><li>SRI can increase yield compared to normal TP. </li></ul>
