Greater and sustainable winter sorghum productivity in Vertisols of Semi-Arid
Tropics in south India in farmers' fields can be achieved through rainwater
conservation, nutrient management and cultivation of an improved variety. In
view of this situation, a study was conducted on farmers' fields to assess the effect
of in-situ moisture conservation practices, integrated nutrient management and
cultivation of improved winter sorghum cultivars on sorghum productivity in
Vertisols of south India. Compartmental bunding along with integrated nutrient
management and improved sorghum cultivars potentially stabilized the winter
sorghum productivity in the rainfed Vertisols. Lay out of farmer fields with
compartmental bunding increased sorghum grain and straw yields by 13% to 14%
and 14% to 26% over no compartmental bunding in Bellary district of Karnataka
and Kurnool district of Andhra Pradesh states, respectively in India Integrated
nutrient management at 60 kgNwith 3 tFYMha-1 and Azospirillum seed treatment
increased sorghum grain yield from 24% to 27% and straw yields from 23% to
39% compared to farmers practice of nutrient application at 10 kgN+ 3 tFYMha
in both Bellary and Kurnool districts, respectively. Sorghum cultivar “CSV-216R”
produced 8% to 10% higher grain yields over local “M35-1'' cultivar in Karnataka
and Andhra Pradesh states, respectively. Cultivation of “CSV-216R'' cultivar of
winter sorghum with formation of compartmental bunding during June and
application of 60 kg N ha + 3 t FYM ha withAzospirillum seed treatment
produced greater net returns of 21418 ha and 21058 ha with higher B:C ratio
of 2.29 and 2.31 compared to lower net returns of 11754 ha and 11152 ha with
B:C ratio of 1.84 and 1.81 with farmers cultivation practices observed in Bellary
and Kurnool districts, respectively.
