Moisture use Efficienty of Dry Land Crops as Influenced by Fertiliser Use III. Oilseed Crops

Abstract

Impact of fertiliser use on drylands in improving the moisture use efficiency of various oilseed crops is reported Sarson proved to be an efficient utilizer of conserved soil moisture as compared to linseed. Highest moisture use efficiency was exhibited when it. was fertilised with 40 kg N/ha. Half soil and half foliar method resulted in relatively higher moisture use efficiency. Placement proved more efficacious in case of linseed fertiliser use resulted in higher yields and moisture use efficiency of all oilseed crops except groundnut tried at Jodhpur. Under late sown conditions. castor gave the highest moisture use efficiency, followed by sunflowers. In good rainfall years like 1973. groundnuts gave higher yield than castor and sunflowers and moisture use efficiency.
