abstract radiation, water and co2 are three major resources requirement for crops growth and development and within a wide range, increasing each of them would increase the biosphere productivity. higher usage of fossil fuels is increasing the atmospheric co2 and according to known crop physiological functions, such conditions should increase the crops production. however there is a possibility...

introduction evapotranspiration is one of the most important elements of hydrological cycle which is required for water resource management and design of irrigation systems. crop evapotranspiration (etc) can be measured by the lysimeter using water balance equation. it also can be estimated by multiplying reference evapotranspiration (eto) and crop coefficient (kc). considering the importance o...

this study was undertaken to identify morphological changes in young seedlings of 5 iranian almond species (prunus dulcis, p. eburnea, p. eleagnifolia, p. haussknechti, and p. scoparia) under polyethylene glycol-induced drought stress. drought stress caused a significant reduction in plant growth parameters such as fresh and dry weights of plant organs, leaf number, total leaf area, and leaf re...

introduction: lack of water and deterioration in the quality of soil and water resources are considered to be the prime cause of reduced crop yield in arid and semi-arid regions ‘more crop per drop’ by trickle irrigation, deficit irrigation, and uncommon water are the best strategies for mitigating water crises. different irrigation management strategies are needed to increase production in dif...

The experiment was conducted at the research farm of ICAR- Central Coastal Agricultural Research Institute, Goa, India during 2016–2019 to estimate crop water requirement (CWR) pineapple different growth stages and compare performance economic viability irrigation systems. Crop calculated based on consolidated weather data 14 years evapotranspiration (ETc) using Penman-Montieth equation CROPWAT...
