摘要

本研究于2022-23年在哈里亚纳邦的库鲁舍特拉、卡纳尔和亚穆纳纳加尔三个地区进行,目的是分析直接播种水稻(DSR)生产中的资源利用效率和制约因素。为了达到研究的目的,采用了Cob-Douglas生产函数技术。研究结果表明,直接播种的巴斯马蒂水稻和种子的机器劳动和灌溉投入、直接播种的非巴斯马蒂水稻的人力劳动和灌溉投入均大于1,表明这些资源未得到充分利用。直接播种的巴斯马蒂水稻的种子、化肥和人力投入低于1,而直接播种的非巴斯马蒂水稻的化肥和机器劳动投入低于1,表明这些投入过度使用。由于DSR技术是一种节水、节约劳动力和节能的做法,因此需要在农民中推广,为水稻种植者面临的问题提供可行的解决方案。杂草丛生和管理、缺铁、没有DSR钻头和土地准备困难是农民在DSR生产中面临的主要问题,需要采取适当的补救办法。

Resource Use Efficiency and Constraints in the Production of Direct Seeded Rice in Haryana, India
The present study was conducted during 2022-23 in three districts namely, Kurukshetra, Karnal and Yamunanagar in Haryana with the objective to analyse the resource use efficiency and constraints in the production of direct seeded rice (DSR). To achieve the objective of the study Cob-Douglas production function technique was used. The result of the study revealed that inputs like machine labour and irrigation in direct seeded basmati paddy and seed, human labour and irrigation in direct seeded non-basmati paddy were greater than one indicating underuse of these resources. The seed, chemical fertilizers and human labour in direct seeded basmati paddy while chemical fertilizers and machine labour in direct seeded non-basmati paddy were less than one which indicated the overuse of these inputs. As DSR technology is a water, labour and energy saving practice, it needs to be popularized among the farmers by offering viable solutions the problems faced by the rice growers. Weed infestation and management, iron deficiency, non-availability of DSR drill and difficulty in land preparation were the major problems faced by the farmers in the production of DSRs which warrant appropriate remedial solutions.
