Abstract
A three-year field experiment was conducted at the Agricultural Research Station of Mandor, Jodhpur, Rajasthan, under arid climatic conditions in the rabi season of 2016–2019 with the objectives of evaluating the effect of drip irrigation and fertigation levels on cumin plant growth, yield, oil content, water-use efficiency, and water productivity. The pooled data revealed that the drip irrigation at 0.6 cumulative pan evaporation (CPE) recorded significantly higher plant height (31.4 cm), umbels plant−1 (50.4), umbellates umbel−1 (5.07), seeds umbel−1 (5.34), test weight (4.60 g), seed yield (1063 kg ha−1), gross return (₹ 172,600 ha−1), net return (₹ 113,500 ha−1) and benefit, and cost ratio (2.9) over drip fertigation at 0.4 CPE and surface irrigation with 0.8 CPE. The fertigation with 80% recommended dose of fertilizer (RDF) being at par with 100% RDF recorded a significantly higher number of umbels plant−1 (50.0), umbellates umbel−1 (5.03), seeds umbellate−1 (5.24), test weight (4.67 g), seed yield (1052 kg ha−1), gross return (₹ 170,900 ha−1), net return (₹ 111,700 ha−1), and benefit cost ratio (2.9) over fertigation with 60% RDF and control. Maximum water-use efficiency (5.7 kg ha−1 mm−1) and water saving (39.04%) was observed under drip irrigation at 0.4 CPE followed by 0.6 CPE (4.8 kg ha−1 mm−1 and 18.86%, respectively).

Maximum cumin seed yield was recorded with an application of drip irrigation at 0.8 cumulative pan evaporation (CPE) followed by drip irrigation at 0.6 CPE during each experimental year except for 2016–2017
Our results revealed that the maximum plant growth and cumin seed yield was recorded with the application of fertigation with 80% RDF followed by fertigation with 100% RDF during all the years of the experiment
