Abstract
A field experiment was conducted in farmer’s field near College of Sericulture, Chintamani, during late Kharif - 2014 to study the effect of integrated nutrient management practice on growth and yield of mulberry. Experiment was laid out in RCBD design with eight treatments replicated thrice. Among different treatments, application of FYM at 20 t ha-1 + 50% inorganic N + pongamia cake (25% N equivalent)
+ 75% P & 100% K inorganic + Azospirillum + PSB + Pseudomonas florescencehas recorded significantly higher leaf yield (13.42 t ha-1) which was on par with FYM at 20 t ha-1 + 50% inorganic N + pongamia cake (25 % N equivalent) + 75% inorganic P & K + Azospirillum + PSB + Pseudomonas florescence (13.23 t ha-1) and FYM at 20 t ha-1 + 50% inorganic N + pongamia cake (25% N equivalent) + 100% inorganic P & K + Azospirillum + PSB (13.07 t ha-1). These treatments also showed similar trend in growth and quality parameters. Whereas, significantly lower leaf yield was recorded in FYM at 20 t ha-1 + recommended dose of NPK (9.03 t ha-1). Whereas, higher net returns ( 30158 . ha-1) and B:C ratio (1.80) was recorded with FYM at 20 t ha-1 + 50% inorganic N + pongamia cake (25% N equivalent) +75% P & 100% K inorganic + Azospirillum + PSB + Pseudomonas florescence.
