Study on Effect of Supplementary Irrigation on Rainfed Chickpea (Cicer arietinum L.)

Abstract

Chickpea is one of the important winter legumes in Nepal. It is grown after rice or maize either as sole or mixed crop. In Nepal, chickpea is mostly grown as rainfed crop on residual soil moisture or sometimes under irrigation. Lack of irrigation results drought and heat stress which affects crop growth and development. Irrigation at proper time is one of the most important factors for achieving higher crop yield. The experiment regarding use of supplementary irrigation time on chickpea was carried out at Regional Agricultural Research Station, Khajura, Banke, Nepal during the winter season of the year 2011 and 2012. The experiment was laid out in Randomized Complete Block Design with three replications. Seven different time intervals of irrigation was applied in the experiment for both years. Treatments differed significantly in terms of grain yield but showed non -significant difference in days to flowering and maturity over the years. The combined analysis of the experiments showed that the highest grain yield (2318 kg/ha) was produced when irrigation was supplied at vegetative stage followed by irrigation supplied at flowering stage (2298 kg/ha) and pod fill stage (2104 kg/ha) respectively.Int J Appl Sci Biotechnol, Vol 3(3): 431-433

Effects of supplemental irrigation on yield and yield attributes of chickpea (Cicer arietinum L.) in western Ethiopia

“…Significantly high yield was found with one-time irrigation at pod-filling (Shamsi et al, 2010) or at vegetative stage followed by irrigation at flowering and at pod-filling stage (Acharya et al, 2015) in comparison with that which was found in rainfed condition. Singh et al (2016) also reported that irrigation at pod-forming stage significantly increased seed yield by 36% in the first season and irrigation at flowering increased the value by 7%…”

“…The lowest yield was observed in rain-fed condition in the two-year study. Compared to rain-fed condition, application of SI twice at (Shamsi et al, 2010;Yagmur and Kaydan, 2011;Rasaei et al, 2012;Silva et al, 2014, Acharya et al, 2015Singh et al, 2016;Ouji et al, 2016), which stated that irrigation had significant effect on chickpea yield. The use of SI at vegetative, flowering and pod-filling stages is essential for obtaining higher grain yield of chickpea (Acharya et al, 2015).…”

Low water supply differentially affects the growth, yield and mineral profile of kabuli and desi chickpeas (Cicer arietinum)

“…Chickpeas, in particular, are mainly grown under rainfed conditions in resource-poor, arid and semi-arid regions, being subjected to terminal drought that decreases plant yields by up to 50% (Sabaghpour et al, 2006;Toker et al, 2007). Drought stress impairs key physiological and biochemical processes, whilst irrigated cropping systems, particularly before flowering, resulting in an increase in plant population, dry mass, photosynthetic area, pod filling and water use efficiency (Acharya et al, 2015;Geethanjali et al, 2018;Pendergast et al, 2019). Thus, the limitations imposed by climate change and, in particular, the depletion of water resources in the soil resulting from more frequent and severe drought events will negatively affect the productivity of this crop.…”
