Abstract

Chickpea or gram (Cicer arietinum L.) is the leading pulse crop of India, covering almost 7.29 million ha area. During the last 2 decades, chickpea output has gone up from 4.75 million tonnes to 5.77 million tonnes; mainly owing to yield gain of 130 kg/ha. Technological advancement has helped to stabilize the chickpea production in the country despite its cultivation being relegated to marginal environments. Past efforts have been rewarding in insulating varieties against biotic stresses by way of standardization of screening techniques, morphological characterization of causal agents, detection of racial differences etc.. Keeping this in view, an experiment was conducted in adopted village Koste under NICRA project, Krishi Vigyan Kendra, Balaghat, Madhya Pradesh during winter (rabi) season of 2011-12, 2012-13 and 2013-14 in laboratory and field surroundings to evaluate influence of weather parameters on wilt caused by Fusarium oxysporum f. sp. ciceris in ‘JG-11’ and ‘JG-16’ chickpea (Cicer arietinum) cultivars. Under controlled laboratory experiments, the growth and sporulation of F. oxysporum f. sp. ciceris was observed at different temperatures. The ‘JG-16’ showed larger incubation period, less wilt prevalence and higher yield in comparison to ‘JG-11’. 20th November sowing minimizes wilt incidence in both the cultivars. Lowest mean wilt incidence (19.3, 16.5 and 14.22%) and maximum mean grain yield (1431, 1452 and 1456 tonnes/ha) were recorded in the crop sown on 20th November during three years. Maximum and minimum ambient temperature and soil temperature were positively and significantly correlated with wilt incidence in ‘JG-16’.
