Study on effect of different moisture treatments on yield and some agronomic characters in lentil(Lens culinaris L.)genotypes

摘要

Drought stress is one of the most important abiotic stresses for rainfed crops in Iran.Most of the lentil area(92 percent)in Iran is rain fed.To investigate the effects of different moisture treatments on yield and some agronomic characters,an experiment was carried out at the Research Station of Ekbatan,in Hamedan province,in a split plot design with four replications during the 2010-2011 cropping season.The main plots had 4 different moisture levels(irrigation at flowering,irrigation at podding,irrigation at flowering and podding,and no irrigation)and the sub-plots had 5 genotypes(‘ILL 6037’,‘Cabralinta’,‘ILL 325’,‘ILL 857’ and local check).The result showed that the interaction of different moisture treatments and genotypes was significant for all traits except number of primary branches per plant and 100 seed weight.Averaged over all the genotypes,the highest seed yield was obtained with irrigation during podding(1136 kg/ha)and it was 3.6 times than that under check(rainfed).Local check produced highest average seed yield(936 kg/ha).Therefore,it is recommended that for spring planting local cultivar should be grown and it should be irrigated during podding.
