Abstract Field trials were conducted in 2005–2007 to asses the effect of integrated nutrient management on strawberry yield and soil nutrient status. There was a substantial increase in soil organic carbon and available nutrient content by FYM, urea and Azotobacter applied alone or in combination. The highest organic carbon content of 0.63% was recorded in treatments where full nitrogen as FYM + Azotobacter or 75% nitrogen through FYM + 25% nitrogen as urea + Azotobacter was applied. However, highest available N and P of 256.4 and 19.7 kg ha−1 was observed when 25% N was applied as FYM + 75% N through urea + Azotobacter whereas full dose of N applied as FYM + Azotobacter resulted in highest available soil K (141.5 kg ha−1). Calcium and magnesium build up was highest (7.88 and 2.95 m eq 100 g−1 soil) in treatment where full N was applied as urea + Azotobacter. Maximum strawberry yield of 372.89 q ha−1 was obtained with the application of full N as urea along with Azotobacter whereas a yield of 358.43 q ha−1 was recorded with the application of 25% N in the form of FYM + 75% N through urea + Azotobacter and were at par with each other. Top Key words Azotobacter, FYM, integrated nutrient management, organic carbon, strawberry, urea. Top |
