Canopy temperature is a useful indicator of crop water stress and can also be used for making timely irrigation scheduling decisions for center pivot and subsurface drip irrigation systems. However, it is not known how closely the measured canopy temperature from a circular area of the canopy surface compares with a larger continuous area that includes the full canopy width. A study was conduct...

Agricultural productivity in irrigated areas depends on several factors, including the design and maintenance of irrigation systems. Excessive or insufficient applications water affect plant growth development, hence agricultural productivity. For this reason, evaluation system is essential to avoid loss during application. This study aimed evaluate efficiency uniformity a subsurface drip sugar...

this study was conducted to determine the possibility of a crop water stress index (cwsi) to schedule irrigation for pistachio tree under subsurface drip irrigation. the effects of two irrigation intervals consisting 3 (i3) and 14 (i14) days based on measuring soil water content were investigated on the cwsi. from 22 may (doy 143) to 22 september (doy 266), the evapotranspiration in i3 and i14 ...

Adoption of drip irrigation in Kerala State of India is very low and potential exists toincrease its adoption in the State. A field survey was conducted in two districts to determine themajor factors influencing farmers’ adoption of drip irrigation and to draw conclusions that willhelp in developing policy and institutional interventions to encourage the adoption. The resultsindicated that adop...

Proper N fertilizer and irrigation management can reduce nitrate leaching while maintaining crop yield, which is critical to enhance the sustainability of vegetable production on soils with poor water and nutrient-holding capacities. This study evaluated different methods to measure nitrate leaching in mulched drip-irrigated zucchini, pepper, and tomato production systems. Fertigation rates wer...
