Abstract
A field experiment conducted during 1987 and 1988 showed possibility for cultivation of cotton (Gossypium sp.) as summer crop and as a ratoon crop (second flush) during the rainy season, with an average productivity of 24.4 qha (12.8 qha from summer crop and 11.6 qha from ratoon crop). The summer crop required 10 irrigations administered at 80 mm cumulative pan evaporation (CPE) for optimum production. However, use of mulch along with, application of jalshakti @ 5 kgha in furrows considerably reduced the irrigation requirement of summer crop. From an overall consideration of yield, return, water economy, water-use efficiency, easy availability of mulching material, 6 irrigations at 120 mm CPE may be provided to summer crop of Vikas cotton superimposed with maize-stover mulch in between the crop rows.References
