Evapotranspiration and water-use efficiency of chilli crop (Capsicum annum L.) in arid environment
Journal of Agrometeorology, 2011 Lysimetric studies on chilli crop Capsicum annum L. cv. Haripur and Raipur) were conducted at Jodhpur during three kharif seasons viz., 2006, 2007 and 2008 to determine evapotranspiration requirements during different growth stages under three ...

Evaluating spatial and temporal variations in sub-field level crop water demands
Frontiers in Agronomy, 2022 Variable rate irrigation (VRI) requires accurate knowledge of crop water demands at the sub-field level. Existing VRI practices commonly use one or more variables like soil electrical conductivity, historical yields, and topographic maps to delineate ...

New Approaches to Irrigation Scheduling of Vegetables
Horticulturae, 2017 Using evapotranspiration (ET) data for scheduling irrigations on vegetable farms is challenging due to imprecise crop coefficients, time consuming computations, and the need to simultaneously manage many fields.

Estimation of crop water requirements: extending the one-step approach to dual crop coefficients [PDF]
Hydrology and Earth System Sciences, 2015 Crop water requirements are commonly estimated with the FAO-56 methodology based upon a two-step approach: first a reference evapotranspiration (ET0) is calculated from weather variables with the Penman–Monteith equation, then ET0 is multiplied by a ...

Enhancing Water and Soil Resources Utilization via Wolfberry–Alfalfa Intercropping
PlantsThe impact of the intercropping system on the soil–plant–atmosphere continuum (SPAC), encompassing soil evaporation, soil moisture dynamics, and crop transpiration, remains an area of uncertainty.

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network
FEBS Letters, EarlyView.Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.
