Effect of irrigation schedule on yield, water use and oil content of toria (Brassica napus var napus)

Abstract

A field experiment was conductcd during 1987--88 1989-90 to on sandy-loam soil at Sriganganagar, to study the effect of irrigation schedule on yield6, water use and oil content of torin (Brmsica napus L. var. napus sensu stricto; syn. 23. conrpestris Hook. f. Tho* vva COM Duthie &Fuller). TOM responded significantly to irrigation levels. Mean maxinium seed yield of 13.5 q h a was recorded under 2 irrigations given at branching and siliquas, development stage-closely followed by that with 2 irrigations at , branching and flowering. Oil yield was significantly higher with 2 irrigations applied at branching and siliqua-development stages. Consumptive use of water and water-use efficiency were 250 nun and 5.39 kgha-mm respectively with 2 irrigations scl~eduled at branching and siliqua-development stages.
