Abstract:Chickpea (
Cicer arietinum L.) stands as a crucial rabi pulse crop within India, playing a significant role in bolstering food security and meeting nutritional requirements. Nevertheless, the challenge of water scarcity during critical growth phases poses a notable obstacle to chickpea cultivation, especially in rainfed regions. To tackle this concern, we executed a field study during the rabi season to explore the influence of varying irrigation frequencies and mulching methods on the growth and yield aspects of chickpea.
The research involved eight distinct treatment combinations, encompassing two irrigation frequencies: a single instance of irrigation during the pre-sowing and flowering stage, and a double irrigation approach covering pre-sowing, flowering, and pod-filling stages. These irrigation strategies were coupled with four different mulching techniques: absence of mulch, utilization of black poly mulch, deployment of non-woven mulch, and application of biodegradable mulch.
The results of our investigation underscore that the employment of biodegradable mulch in conjunction with a single irrigation event produced the most favorable outcomes. This specific treatment exhibited superior characteristics such as maximum plant height, primary branches per plant, pod count per plant, seed weight per pod, and yield per hectare. Moreover, this treatment approach demonstrated the highest levels of water use efficiency.
This study accentuates the importance of embracing sustainable irrigation practices that conserve water, along with implementing effective mulching methods. By doing so, chickpea production can be optimized, water use efficiency enhanced, and the overarching goal of ensuring food security can be upheld.
