An Optimal Irrigation Scheduling for Drip Irrigated Onion in A- Semi-Arid Region Using the Computer Program CROPWAT 8.0

Yield and quality responses of drip-irrigated spinach to different irrigation quantities in a semi-arid region with a high altitude

The effect of different irrigation quantities on the growth, marketable yield, crop quality (antioxidant activity, mineral and total phenolic content) and irrigation water use efficiency (IWUE) of spinach grown in a semi-arid region of high altitude (1795 m a.s.l.) was determined. Plants were irrigated with three different irrigation quantities which determined considering 100 (I1), 85 (I2) and...

Irrigation Strategies to Minimize Nitrate Leaching for Drip Irrigated Tomatoes

Irrigation Scheduling for Maize and Indian-mustard based on Daily Crop Water Requirement in a Semi- Arid Region

Maize and Indian mustard are significant crops in semi-arid climate zones of India. Improved water management requires precise scheduling of irrigation, which in turn requires an accurate computation of daily crop evapotranspiration (ETc). Daily crop evapotranspiration comes as a product of reference evapotranspiration (ET0) and the growth stage specific crop coefficients modified for daily var...

Comparison of Nitrogen Fertilization Methods and Rates for Subsurface Drip Irrigated Corn in the Semi-Arid Great Plains

In semi‐arid areas such as western Nebraska, interest in subsurface drip irrigation (SDI) for corn is increasing due to restricted irrigation allocations. However, crop response quantification to nitrogen (N) applications with SDI and the environmental benefits of multiple in‐season (IS) SDI N applications instead of a single early‐season (ES) surface application are lacking. The study was cond...

Effect of deficit irrigation on crop growth, yield and quality of onion in subsurface drip irrigation

Indiahas the largest area under onion (Allium cepa) crop but its average productivity (14.21 t ha-1) is considerably lower than the world’s average of 19.4 t ha-1. Besides low productivity, irrigation efficiencies are also very low i.e. 30-35% in India. Managing onion crop with less than adequate irrigation water availability is a challenge in several parts of the country. Options of i) deficit...
