Impact of integrated application of KSB, chemical fertilizers along with organic manures on nutrient uptake and yield of wheat in vertisols of central India

Abstract

The present field experiment was conducted to study the effect of integrated application of seed inoculation of KSB, chemical fertilizers along with FYM and vermicompost on nutrient uptake and yield on Vertisols during rabi 2024-25 at Research Farm, Dept. of Soil Science, Dr. PDKV, Akola. The experiment was carried out in randomized block design with eight treatments replicated thrice. The treatments comprising of T1: Absolute Control, T2: 100% RD), T3: 100% RDF + KSB, T4:75% RDF + KSB, T5: 75% RDF + FYM @ 5t ha-1, T6: 75% RDF + KSB + FYM @ 5t ha-1, T7: 75% RDF + Vermicompost @ 2.5 t ha-1, T8: 75% RDF + KSB + Vermicompost @ 2.5 t ha-1. The results revealed that, the integrated application of seed inoculation of KSB + 75 % RDF + vermicompost @ 2.5 t ha-1 recorded significantly higher nutrient uptake and yield of wheat followed by application of seed inoculation of KSB + 75 % RDF + FYM @ 5 t ha-1 which was statistically at par with each other. The lowest nutrient uptake and wheat yield was observed under control treatment. Hence, it can be concluded that the integrated application seed inoculation of KSB and 75 % RDF along with vermicompost @ 2.5 t ha-1 or FYM @ 5 t ha-1 found beneficial for enhancing nutrient uptake and wheat yield in Vertisols of central India.
