Abstract

The experiment, conducted at COART, Akola during Kharif 2021-22, evaluated the impact of various vermicompost doses on physical and physico-chemical properties of Non-GM cotton cultivars in rainfed agriculture. Employing an FRBD with eight treatments replicated thrice, the study revealed that the application of 60 kg N ha-1 through vermicompost (T4) led to the most significant improvements: reduced soil bulk density (1.24 Mg m-3), increased water holding capacity (58.22%), and elevated organic carbon content (5.67 g kg-1). The Hirsutum cultivar, Chetna J1, displayed the best results. Conversely, the lowest pH (7.57) and EC (0.25 ds m-1) were observed in treatment T2, where 60 kg N ha-1 was supplied through vermicompost to the Arboreum cultivar, AVC 14.
