ABSTRACT
The present investigation was conducted to study the effect of soil and foliar application of organic nanofertilizer on biometric, yield and post-harvest soil nutrient status. The field experiment was carried out during the year 2017-18 at College of Agriculture, Vellayani. Fertilizer samples were analysed and particle size of granular organic nano NPK and liquid organic nano NPK were 89.26 nm and 67.30 nm respectively. Five randomly selected plants were tagged from each plot and fruits from that tagged plants were collected for calculating fruit length, girth of fruit and that five tagged plants also harvested at the final picking to calculate nutrient uptake by bhindi plant. The soil samples were also collected at the final harvest of the crop for calculating nutrient status of the post-harvest soil. From the result it was indicated that among the different treatment combinations, application of FYM (12 t ha-1) + Soil application of nano NPK (12.5 kg ha-1) + Foliar application of nano. NPK.(0.4%) was found to be beneficial in recording higher uptake of nutrients both plant as well as fruit and nutrient status of the post-harvest soil.
