Effect of Various Levels of Phosphorus on Growth Attributing Characters, Yield and Nutrient Uptake by Cotton in Vertisol

Abstract

This study was carried out at Research Farm of Cotton Research Unit of Dr. Panjabrao Deshmukh Krishi Vidyapeeth Akola during the kharif season of 2021-2022 to evaluate the "Effect of various levels of phosphorus on growth attributing characters yield and nutrient uptake by cotton in Vertisol". The experiment used Randomized Block Design, with eight treatments replicated thrice. The prescribed fertilizer dose of 120:60:60 NPK kg ha-1 was administered according to the treatments. The research experiment used the cotton variety PDKV JKL116. Similarly, Depending on the treatment, nano DAP was applied during seed treatment and foliar spray at 30 DAS. Before and after harvesting, samples of the soil and cotton plants were collected and analyzed using procedures’. The results concluded that the application of 100% NPK achieved the highest plant height, branch number boll number seed cotton yield, and cotton stalk yield.
