OPTIMIZED SUBSURFACE IRRIGATION SYSTEM (OPSIS). THE FUTURE OF SUGARCANE IRRIGATION

Abstract

An experiment was conducted in Sugarcane Research Institute (SRI) Faisalabad during 20172018 and 2018-2019 cropping seasons to find out the effect of different irrigation levels on growth and yield parameters of five sugarcane clones. Sugarcane is a tropical crop with C4 Photosynthetic metabolism. Due to irrigation water shortages, water stress is common in sugarcane. Major Responses of drought in sugarcane is leaf rolling. Stomatal Closure inhibition of stalk and leaf growth, leaf senescence and reduced leaf area (due to its phenomenal dry matter production capacity) are other symptoms of water stress.
