Bazı Yetiştirme Tekniği Öğelerinin Nohutta Verim Ve Verim Unsurlarına Etkisi

Abstract

Trials were conducted to investigate the effects of some agronomic practices on chickpea yield and yield components at Tokat, Sivas and Ankara provinces during 1991 and 1992. ‘Split-split plot design” was used; sowing treatments (drilling, broadcasting), seeding times v- (early, late) and fertilizer application (with and without fertilizer) treatments were performed. Experimental material consisted of one Ascochyta blight sensitive local chickpea population, one tolerant cultivar (Eser 87), and one resistant candidate cultivar (ILC 195/2). Extensive Ascochyta blight infestation was observed at all locations in 1991 and only at Sivas location in 1992. Drilling treatment significantly increased seed yield, plants/m2, and number of seeds/plant in some trials. Significant differences in 100 seed weight were not observed between sowing treatments. Early seeding significantly increased seed yield and number of seeds/plant except second year at Sivas location. Number of plants/m2 was higher in late seeding times of all trials. 100 seed weight increased with late seeding time at the locations and years with disease infestation and with early seeding time at the locations and years with no disease infestation. Although there was a variation in seed yield and seed/plant by years and locations, Ascochyta resistant and tolerant varieties, were still the highest group. 100 seed weight of the varieties ranked in the order of Eser-87, ILC-195/2, population where disease occurred and population, Eser-87, ILC-195/2 where no disease prevailed. There were no differences among plant/m2among of varieties under no disease, but differences under disease. Increase via fertilization in seed yield and seed/plant at all trials, was not statistically significant. Fertilization had effect on 100 seed weight.
