Evaluation of field water balance-based deficit irrigation strategies for seasonal sugarcane (Saccharum officinarum L.) in a semiarid Indian plain S. K. Dingre, S. D. Gorantiwar Irrigation and Drainage, 2023 The impact of deficit irrigation (DI) on sugarcane (Saccharum officinarum L.) growth, yield and quality was investigated in field experiments during 2015–2017. The treatments included applying water deficit at three levels (0%, 30% and 60%) during three growth stages (development, mid‐season and end) in order to investigate the impact of a specific water deficit during each growth stage separately. The experiment included 27 treatments replicated twice in a randomized block design. Irrigation scheduling was based on the field soil water balance in the root zone and the water deficit that needed to be provided in the respective treatments. The study found that as the water deficit increased, the growth, yield characteristics and sugarcane yield decreased. Deficit‐free irrigation throughout the season registered maximum cane yield (174 t ha−1). Water deficits of 30% and 60% throughout the season reduced sugarcane yield by 14% and 40.7%, respectively, compared with the condition without water deficit. Based on the statistical comparison of yields, the mid‐season stage was identified as the most sensitive stage, followed by the development and end stages according to DI criteria. A water deficit applied at the end of the season had only a minor impact on yield. Without significant yield loss, an irrigation strategy for deficit conditions of 0% water deficit in the development stage, 30% in mid‐season and 60% at the end stage was found to be sufficient. Sugarcane quality parameters did not change substantially when there was a water deficit.
Sugarcane response to different soil water replenishment-based deficit irrigation treatments during different growth stages in an Indian semi-arid region* S.K. Dingre, S.D. Gorantiwar, D.D. Pawar, S.D. Dahiwalkar, C.A. Nimbalkar Irrigation and Drainage, 2021 The objective of this study was to investigate the effect of a specified water deficit during a specified growth stage by replenishing root zone soil water. A field experiment was conducted with 27 treatments in randomized block design comprising groupings of different root zone soil water replenishment levels (100%, 70%, and 40%) during different growth stages (tillering, grand growth, and maturity) over three full‐year seasons of 2015–2017 in clay soils of semi‐arid western India. The full‐season 100% soil water replenishment produced higher yield (174 t ha−1), net monetary returns, and benefit‐cost (B:C) ratio that decreased linearly with linear decrease in water use. Full‐season 40% soil water replenishment caused a reduction in yield of about 40.7%, whereas a 70% replenishment caused a reduction in yield by 14%. The quality parameters of sugarcane improved non‐significantly in high‐water‐deficit conditions compared with full irrigation. The smaller range of water productivity in all seasons indicated a linear decrease when irrigation water increased and yields decreased under the different treatments. The net income and B:C ratio related to marketable cane yield was highest in 100% soil water replenishment (INR 274,000 ha−1and 1.58, respectively) and then declined with the decrease in water use depth. The water deficit imposed during the long‐duration grand growth stage had adverse effects on cane yield, followed by tillering and maturity stages. Deficit irrigation scheduling at 100%, 70%, and 40% soil water replenishment at tillering, grand growth, and maturity stages, respectively, was appropriate. The water requirement of seasonal sugarcane under full irrigation and water deficit conditions was 1,320 and 1,150 mm, respectively.
Performance of cabbage at different irrigation levels under drip and microsprinkler irrigation systems* M.G. Shinde, D.D. Pawar, K.D. Kale, S.K. Dingre Irrigation and Drainage, 2021 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.
