Comparison of methods for evaluating the suitability of Vertisols forGossypium hirsutum(Bt cotton) in two contrasting agro-ecological regions

Abstract

Cotton (Gossypium sp.) is a major crop grown under rainfed conditions in Vertisols and associated soils in semi-arid tropical (SAT) regions of Peninsular India. In recent years, cotton productivity has declined due to various biophysical factors including pest and diseases, seasonal water stress soil degradation and poor crop management practices. In this study, we compare two methods for evaluating the suitability of Vertisols for cotton in contrasting two agro-ecological regions viz., sub-humid moist (SHM) region and semi-arid (SAD) were characterized. Twelve cotton growing Vertisols (seven from SHM and five from SAD) were evaluated for their suitability for cotton cultivation using soil quality index (SQI) and modified Sys-FAO method. SQIs were

“…Sonegaon soils are marginally suitable for all the major crops grown in the region. Soil depth was the limiting factor for pigeon pea and cotton cultivation (Karthikeyan et al 2019).…”
