STUDY THE EFFECT OF METHANOL FOLIAGE SPRAYING ON CHICKPEA CULTIVARS IN RAINFED CONDITION

摘要

In order to study the effects of methanol foliage spraying on some characters of chickpea cultivars in rainfed condition, an experiment was carried out as split plot experiment based on a randomized complete block design with three replications at Research Field of Faculty of Agriculture and Natural Resources, Islamic Azad University-Sanandaj branch during 2012 growing season. The first factor was Methanol foliage spraying in concentrations as: 0 (control), 10, 20 and 30 volumetric percentages as themain factor and second factor was four chickpea cultivars in clouded as: pirozand kaka (desi type) and jam and ILC-482 (kabuli type) that considered as subplot. The results showed that methanol has a significant effect on yield and yield components. Methanol spraying with a concentration of 30% was more effective than other treatments on yield and yield components, as it increased the number of pods, number of seeds per pod and 100 seed weight. In this study, the most and lowest seed yields were recorded in 30% and 0% (control) methanol treatments as: 899.67 and 538.95 kg/ha respectively. The yield of desi type cultivars were more than Kabuli type, also. As the most and lowest seed yield were achieved in kaka and jam cultivars as: 963.97 and 462.01 kg/ha respectively. In this study other characters as: chlorophyll content and canopy temperature in different growth stages and seed protein were affected significantly by methanol and cultivars. Finally seed yield increased as: 28.52% - 66.93% by methanol spraying at different concentration from 10% - 30%.
