Approaches to the management of Vertisols in the semi-arid tropics: the ICRISAT experience
1989
Virmani, S.M. | Rao, M.R. | Srivastava, K.L.
ICRISAT's technology for improved management of Vertisols involves growing two crops in a year. Application of the technology resulted in considerable improvement in erosion control and moisture conservation, higher rainfall-use efficiency, and annual yields of about 3000 kg/ha of cereal and 1000 kg/ha of legume grains for the last 9 years at experimental watersheds. The technology was evaluated in on-farm tests in a few agroclimates of the Indian semi-arid tropics with moderate but dependable rainfall. Gross profits from the improved technology were 2 to 5 times higher than those from the traditional technology, which involved only postrainy-season cropping. The tests also showed that the technology can be adapted to local conditions by suitable modification of one or more of the components involved
