摘要

大麦是一种营养丰富的谷物,因其多种健康益处而受到利益攸关方的青睐,但令人担忧的是其种植面积不断下降,可能是由于缺乏市场和具有竞争力的定价策略。在其他选择中,合同农业被广泛建议为更好的价格实现和有保障的市场。在此背景下,本研究于2013- 2015年在印度的四个主要大麦种植邦进行,即哈里亚纳邦、中央邦、拉贾斯坦邦和北方邦,利用回归树方法从随机选择的400名农民样本中确定合同农业的决定因素。研究结果表明,签约农民的平均产量为4791公斤/公顷(n=90),而非签约农民的估计产量为3549公斤/公顷(n=310),这意味着产量优势为35%。回归树证实了签约的做法在拉贾斯坦邦很流行。分析还表明,农场规模、种子替代行为、种子来源和大麦种植面积是签约的决定因素。总体而言,该研究表明,尽管有多种好处,但地区在签订合同方面发挥了突出作用。该研究倡导大麦种植者,特别是小农,利用合同农业的优势,除了在大麦生产中自我赋权外,还可以签订合同来降低价格风险。

Determinants of Contract Farming in Barley Production – Regression Tree Approach
Barley, a nutri-rich cereal is gaining momentum among stakeholders owing to multiple health benefits but the concern is its declining area, possibly attributed to lack of market and competitive pricing strategy. Amongst alternatives, contract farming is widely suggested for better price realisation and assured market. In the context, the present study was carried out during 2013-15 in four major barley growing states in India, viz. Haryana, Madhya Pradesh, Rajasthan and Uttar Pradesh for identifying the determinants of contract farming from a sample of 400 randomly selected farmers using regression tree approach. Findings indicated that the average yield of farmers enrolled in contract farming was 4791 kg/ha (n=90) against non-contractors with an estimated yield of 3549 kg/ha (n=310), implying a yield advantage of 35%. The practice of enrollment into contracts was popular in Rajasthan as corroborated by regression tree. The analysis also indicated that farm size, seed replacement behaviour, source of seed and area under barley were turned as deciding factors in contract enrollment. Overall, the study indicated that region plays a prominent role in enrollment into contracts despite multiple benefits availed. The study advocates barley growers to take advantage of contract farming, especially small-holders to enroll into contracts for mitigating price risk apart from self-empowerment in barley production.
