Effect of Cut-Off Irrigation levels on Production of Teosinte Forage Crop in Clay Soil

The present study was carried out at Sakha Agricultural Research Station (clay soils) middle north of Nile Delta area during summer seasons 2021 and 2022 in randomized complete block design with three replications. objective this research to find the response yield, water saving some functions for teosinte forage crop cut-off surface irrigation owing produce " more per less”. Three levels were executed; 100% i.e., full irrigation, 90% 80% irrigation. mean performances plant height, fresh dry yields two combined are significantly affected by applied, whereas normal or control treatment with100% no (Trt. A) has tallest height. On other hand, low level C) shortest plants cuts. Also, traits reduced decrease Both severely decreased when irrigated cut-off. Decreasing than commonly controlled without (Trt.A) markedly all studied growth characters inhibiting effect deficit stress on parameters notably appeared pronounced under that .The obtained results may refer decreasing lowered soil moisture content which restricted mobility nutrients would reduce efficiency physiological metabolic processes needed growth. Regarding relations, resulted several advantages; almost same yield as 10% well highest values crop-water productivity (WP) (PIW). recorded 610 685 Kg/strip compared 585 655kg/strip 90 %irrigation first second cuts, respectively season.
