Drip irrigation and fertigation, being advocated for higher crop and water productivity require optimization of irrigation and fertilization schedules. Field experiments were conducted during 2016–2018 to evaluate water and energy-efficient drip irrigation and fertigation schedules for higher productivity and profitability from oilseed rape. The treatments comprised of a combination of three levels of drip irrigation {60, 80 and 100% of cumulative pan-evaporation (CPE)} and three levels of fertigation {60, 80 and 100% recommended dose of fertilizers (RDF)} along with one absolute control (flood irrigation and soil application of RDF). The yields of crop under drip irrigation at 100 and 80% of CPE were statistically similar but significantly higher than irrigation at 60% of CPE. The irrigation use efficiency (IUE) and water use efficiency (WUE) were maximum at 80% of CPE followed by 100 and 60% of CPE. Drip irrigation at 80% of CPE resulted in 18% higher yield along with a water-saving of 35.4% than absolute control. Energy use efficiency (EUE) was higher at 100% of CPE followed by 80 and 60% of CPE. Whereas, energy productivity at 100 and 80% of CPE being statistically similar but significantly higher than 60% of CPE. Highest benefit: cost (B:C) ratio and net returns were obtained with drip irrigation at 100% of CPE and lowest at 60% of CPE. Fertigation at 100 and 80% RDF recorded significantly higher seed yield than 60% RDF and absolute control.

提倡滴灌和施肥以提高作物和水的生产力需要优化灌溉和施肥计划。在2016-2018年期间进行了田间试验，以评估节水节水的滴灌技术和施肥计划，以提高油菜的生产力和利润率。这些处理方法包括三个水平的滴灌{60、80和100％的累积泛蒸发量（CPE）}和三个水平的施肥{60、80和100％的肥料推荐剂量（RDF）}的组合，以及一种绝对控制方法（RDF的洪水灌溉和土壤施用）。CPE为100和80％时，滴灌下的作物产量在统计学上相似，但显着高于CPE为60％时的灌溉下。灌溉使用效率（IUE）和水使用效率（WUE）在CPE的80％处最高，其次是CPE的100％和60％。与绝对对照相比，在80％的CPE上滴灌可使产量提高18％，节水35.4％。能源使用效率（EUE）在CPE为100％时较高，其次是CPE为80％和60％。相比之下，CPE为100％和80％时的能源生产率在统计上相似，但显着高于CPE的60％。最高收益：滴灌在CPE为100％时获得的成本（B：C）比和净收益在CPE为60％时最低。在100％和80％RDF的施肥条件下记录的种子产量明显高于60％RDF和绝对对照。能源使用效率（EUE）在CPE为100％时较高，其次是CPE为80％和60％。相比之下，CPE为100％和80％时的能源生产率在统计上相似，但显着高于CPE的60％。最高收益：滴灌在CPE为100％时获得的成本（B：C）比和净收益在CPE为60％时最低。在100％和80％RDF的施肥条件下记录的种子产量明显高于60％RDF和绝对对照。能源使用效率（EUE）在CPE为100％时较高，其次是CPE为80％和60％。相比之下，CPE为100％和80％时的能源生产率在统计上相似，但显着高于CPE的60％。最高收益：滴灌在CPE为100％时获得的成本（B：C）比和净收益在CPE为60％时最低。在100％和80％RDF的施肥条件下记录的种子产量明显高于60％RDF和绝对对照。
