INTEGRATED RESPONSE OF INORGANIC AND BIO-FERTILIZERS ON YIELD AND YIELD ATTRIBUTES OF TURMERIC

A field experiment was conducted to study the effect of integration of bio- and inorganic fertilizers on yield and yield attributes of turmeric during 2007-08 and 2008-09 at Udai Pratap Autonomous College, Varanasi, U.P. The experiment was laid out with thirteen treatments consisted of combination of two variety of turmeric (V1 - Padrauna local and V2 - NDH-18) replicated three times in a randomized block design. The results indicated that application of T6 (NPK 180:90:90 kg per ha+Azotobactor chrococcum @ 2.5 kg per ha+Pseudomonas floriscence @ 2.5 kg per ha) significantly increased yield and all yield attributes over all treatments, whereas treatment T9 (50% R.D. of inorganic nitrogen+50% R.D. of inorganic phosphorus+100% R.D. of potash+Azotobactor chrococcum @ 2.5 Kg per ha+Pseudomonas floriscence @ 2.5 kg per ha+50% nitrogen through carpet waste) was closely followed by treatment T6. In respect of turmeric variety, NDH-18 was found superior over variety Padrauna local in all above conditions. On the basis of performance treatment T6 and T9 may be adopted for higher yield and sustainabilit
