Abstract

Inappropriate agriculture operation with dependent on mostly chemical fertilizers has led to acidification and dropping fertility status which directly affects crop productivity. The simplest method to recover these debase land is to amend with integrated nutrient management practices thereby improving the nutrient cycle. We experimented to study the effect of integrated plant nutrient management on yield and leaf nutrient status of broadleaf mustard on farmers' field of Kathmandu Valley from August 2017 to December 2017. The experiment was laid out in Randomized Complete Block Design. There was 9 treatment viz. T1(½ NPK +4 ton/ha Vermicompost), T2( ¾NPK + 2 ton/ha vermicompost), T3 (½ NPK+ 12 ton/ha FYM), T4(¾ NPK + 6ton/ha FYM), T5 ( ½ NPK+ 2 ton/ha Poultry Manure), T6 ( ¾ NPK+ 1 ton/ha Poultry Manure), T7 (½ NPK + 6 ton/ha Compost), T8( ¾NPK+ 3 ton/ha Compost) and T9 (Control) with three replication. All the treatments were applied at the time of transplantation as basal application. In the study maximum plant height and leaves size observed in T5(½NPK+ 2 ton/ha PM) and yield per plot and yield per ha was observed in T6( ¾NPK+ 1ton/ha PM). Similarly, the maximum plant canopy volume was observed in T2 (¾ NPK+ 2ton/ha VC). The highest leaf Nitrogen, Phosphorous, and potash were found in the treatment T7 (1/2 NPK+ 6 ton/ha Compost), T5 (1/2 NPK+ 2 ton/ha Poultry Manure) and T2 (¾NPK+ 2 ton/ha VC) respectively.
