Type: article
Abstract: A field study was conducted during two consecutive years 2006-08, to evaluate the response of site-specific nutrient management (SSNM) on productivity and economics of rice (Oryza sativa L.)wheat {Triticum aestivum (L.) emend Fiori and Paol} cropping system. The total productivity of the cropping system in terms of rice yield equivalent (14.8 t/ha/annum) was the highest with the application of SSNM treatment i.e. N P K S B Mn Zn 150 60 120 40 5 20 25 in rice and N P K in wheat, which was 66.4% higher over farmers practice and 28.2% over state recom- 150 60 120 mended practice. All the yield attributing characters as well as yield of both rice and wheat showed beneficial ef- fects of site-specific nutrient management. Highest net returns of 67,033/ha/annum obtained with SSNM treat- ment, which was 31,681 and 16,905/ha/ annum higher over that of farmers practice and state recommended doses, respectively. Thus, nutrients in ricewheat cropping system may be applied on site-specific soil test basis including micronutrients along with major nutrients for higher productivity and profitability.
