Field experiments were conducted for 3 years to investigate an appropriate irrigation management strategy that would lead to increased cabbage productivity along with saving in irrigation water. Cabbage was grown with microsprinkler and drip irrigation methods with four irrigation levels based on crop evapotranspiration (ETc) as 0.8 ETc, 0.9 ETc, 1 ETc, and 1.1 ETc. It was found that cabbage crop performed better with the microsprinkler system than the drip system. All the growth- and yield-contributing characters in the microsprinkler irrigation method were significantly superior over drip irrigation. The maximum yield of cabbage was obtained by the microsprinkler method (37 t ha⁻¹) with irrigation scheduling at 1 ETc followed by 0.9 ETc (35.5 t ha⁻¹). However, highest water use efficiency (114 kg ha⁻¹ mm⁻¹) was obtained in drip irrigation with 0.9 ETc irrigation level, and the highest net income per mm of water (Rs 622) was obtained in drip irrigation with 1 ETc irrigation level. Microsprinkling gave 7.30% more yield of cabbage than the drip method, whereas the drip method saved 32% more water than the microsprinkler method. It is therefore recommended to adopt the microsprinkler irrigation method to obtain a potential yield of cabbage. However, when water is a limiting factor, it is recommended to grow cabbage with the drip irrigation method.

在滴灌和微喷灌溉系统下不同灌溉水平的甘蓝性能*

进行了 3 年的田间试验，以研究适当的灌溉管理策略，以提高卷心菜产量并节省灌溉用水。使用微喷灌和滴灌方法种植卷心菜，根据作物蒸散量 (ETc) 分为 0.8 ETc、0.9 ETc、1 ETc 和 1.1 ETc 四种灌溉水平。发现使用微喷系统比滴灌系统的卷心菜作物表现更好。微喷灌法的所有生长和产量贡献性状均显着优于滴灌。甘蓝的最大产量是通过微喷水法（37 t ha ^-1）获得的，灌溉计划为 1 ETc，然后是 0.9 ETc（35.5 t ha ^-1）。然而，在 0.9 ETc 灌溉水平的滴灌中获得了最高的用水效率（114 kg ha ^-1  mm ^-1），在 1 ETc 灌溉水平的滴灌中获得了最高的每毫米水净收入（Rs 622） . 微喷法比滴灌法多出 7.30% 的白菜产量，而滴灌法比微喷法多出 32% 的水。因此建议采用微喷灌法来获得白菜的潜在产量。然而，当水是一个限制因素时，建议使用滴灌法种植卷心菜。
