Effect of Nano P on growth & yield of different varieties of groundnut

The experiment was conducted during the Summer season 2023 at the Crop Research Farm Department of Agronomy Naini Agricultural Institute Sam Higginbottom University of Agriculture Technology and Science Prayagraj (U.P.) to find out the Effect of Nano phosphorus on growth and yield of different varieties of groundnut (Arachis hypogaea L.) and Yield validation using SPSS model. The experiment was laid outin Randomized Block Design comprising of 9 treatments which include 3 varieties Kadiri Lepakshi (K1812) Kadiri 6 (K6) and Kadiri 9 (K9) and 3 Different levels of nano phosphorous 2ml/litre 4ml/litre and 6m/litre. Whose effect is observed in Ground nut varieties The result was observed in K-1812 by the application of nano phosphorus at the rate of 6 ml/lit was recorded maximum plant height(61.39 cm) plant dry weight(42.34 g/plant) number of pods per plant(32.87) seed index (42.09 g) pod yield (2.98 t/ha) and haulm yield (4.46 t/ha) and harvest index (40.07 %) were recorded in K-1812 with application of Nano phosphorus at the rate of 6 ml/lit respectively.
