Successful irrigation management of tree and vine crops to control soil salinity requires adequate leaching, which is defined as sufficient water to remove excess salts from the root zone above that required to meet crop demand. Excess salts decrease growth and yield in trees and vines and may lead to more severe effects such as leaf bum and even plant death. The salt tolerances of many crops h...

High fertilizer application and over-irrigation in sugarcane systems can cause considerable N2O emissions. Optimized water-fertilization management which reduces emissions, while maintaining biomass, is crucial, but may affect nitrogen fixation by sugarcane. This study evaluated the combined effect of on biomass field trials southern China. Treatments included drip spray irrigation, with three ...

Abstract Knowledge of the soil water regime in a dynamic equilibrium condition (steady state) emitter–soil–plant system is essential to evaluate adopted irrigation management, aiming maximize use efficiency irrigation. Thus, our objective was determine integrated effect four levels on moisture (θ v ) distribution pattern, mechanical penetration resistance (PR), and sugarcane rooting. Irrigation...

PROCEDURES: We conducted two studies to investigate an integrated program for root rot (Phytopthora fragriae var. rubi) control in raspberries that would be useful to organic and conventional growers. These two studies have been carried out on our commercial field of ‘Meeker’ that was established in 1997 on raised beds with drip irrigation. Soil at this site is naturally infested with the root ...

continuing agricultural expansion and urban development in saudi arabia, (located in an arid climate), together with an increased demands for more water supplies, calls for more efficient irrigation practices, and an increase in crop water productivity (cwp). throughout the present study, a deficit irrigation system was investigated for its impact on soil salinity, crop response factor (ky), cw...

In a three-year experiment (2019–2021), the roots of 7-year-old apple trees (Malus domestica cv. ‘Red Jonaprince’) grown under drip irrigation were studied. The aim study was to determine effect on root density at different depths and distances from trunk. working hypothesis assumed that significantly affects total length roots. treatments corresponding calculated water evapotranspiration (ET10...

The present study was carried out at Lovely Professional university, Phagwara, Punjab during 2019 to the performance of okra under irrigation levels and mulching methods drip irrigation. treatment comprised 3 (1.0 ETc, 0.8 ETc 0.6 ETc) 5 mulch (black plastic mulch, silver straw soil no mulch) laid in split plot design replicated thrice. growth yield attributes were significantly influenced by m...

In this paper, an efficient irrigation system is proposed based on computing evapotranspiration (ET) and the required irrigation quantity using fuzzy inference methodology. The aim of this system is to schedule irrigation according to the particular requirements of a crop and to the change in various climatological parameters and other factors. This is to avoid overor under-watering which signi...
