Effect of integrated nutrient management and spacing on growth parameters, nutrient content and productivity of rice under system of rice intensification

Abstract

Field experiment was conducted to find out the effect of integrated nutrient management and spacing on productivity and economics of rice under system of rice intensification in Palampur, Himachal Pradesh during Kharif 2009-10. The treatments comprising of all possible combinations of three FYM levels (0, 10 and 20 t ha-1) and three fertilizer levels (0, 50 and 100% of the recommended NPK) in main plots and two spacing (20 cm x 20 cm and 30 cm x 30 cm) in sub plots were tested in split plot design, replicated three times. Growth parameters and yield of rice increased consistently and significantly with increase in FYM and fertilizer levels. Significantly highest grain, straw and biological yield were recorded with FYM 20 t ha-1 and application of chemical fertilizers at recommended dose gave significantly highest grain and straw yield. Growth parameters, nutrient content in grain and straw and yield were not influenced significantly by spacing.
