Development of single and dual crop coefficients for drip-irrigated broccoli using weighing type field lysimeters in semi-arid environment
Estimating crop evapotranspiration is critical in effective planning and management of irrigation systems. Accurate estimation of crop water use may aid in achieving economic and environmental benefits by optimizing water resources. Thus, the current investigation aimed to quantify crop evapotranspiration (ETc) & develop single (Kc) and dual crop coefficients for Rabi broccoli. Thus, a 2 years field study was conducted during Rabi 2016–17 and 2017–18 by employing weighing type field lysimeter in a semi-arid climatic condition. Results revealed that, seasonal broccoli ETc was 149 mm (mm) and 144 mm during 2016–2017 and 2017–2018 crop periods, respectively. The Kc values during Rabi 2016–17 were 0.68, 0.84, 1.04, and 0.94 for initial stage (IS), development stage (DS), mid-season stage (MS), and late season stage (LS), respectively. Similarly, in 2017–18, the Kc was found to be 0.67, 0.82, 1.03, and 0.93 during IS, DS, MS, and LS, respectively. In dual crop coefficient approach, the basal crop coefficient (Kcb) was 0.30, 0.66, 0.97 and 0.84 and the soil evaporation coefficient (Ke) was 0.42, 0.23, 0.18 and 0.23 for IS, DS, MS, and LS, respectively. While, during Rabi 2017–18, the Kcb was 0.30, 0.65, 0.98 and 0.85 and Ke found to be 0.41, 0.23, 0.18 and 0.22 for IS, DS, MS and LS, respectively. Study found that the developed crop coefficients were lesser than the food and agriculture organization (FAO) values and thus the precise crop water estimation can be possible utilizing the developed coefficients in the semi-arid climate. The developed regional broccoli crop coefficients may be utilized to improve water productivity in semi-arid environments through meticulous irrigation scheduling. The developed technological knowledge would lead to saving of precious irrigation water with optimal crop production and have environmental benefits by reducing the irrigation water need.
