Effect of Nitrogen Application Timing on Corn Production Using Subsurface Drip Irrigation
The use of subsurface drip irrigation (SDI) in row-crop agriculture is increasing because of potential increases in water and nutrient use efficiency. Research-based information is needed to manage N 'applications through SDI systems in field com (Zea-mays L.) production. This study was conducted to assess the effect of different inseason SDI system N application timings :on corn produ6tion and...
متن کاملNarrow Row Corn Production with Subsurface Drip Irrigation
In the southeastern U.S. Coastal Plains, supplemental irrigation is required to reduce the impact of short‐term droughts and yield‐reducing plant water stress that can occur at least biennially. Sprinkler irrigation is commonly used to water agronomic crops in the region. Microirrigation is typically used for high value fruit and vegetable crops. In recent years and at some locations, microirri...
متن کاملSubsurface Drip Nitrogen Fertigation of Corn
The efficient management of nitrogen (N) fertilizer and irrigation is of utmost importance because they are two of the greatest expenses for corn production. This project was conducted to determine if yield and efficiency of fertilizer N in corn could be improved by applying N at later developmental stages through a subsurface drip irrigation (SDI) system. Experiments in 2014 and 2015 compared ...
متن کاملComparison of Subsurface Drip Irrigation Uniformity Designs on Cotton Production
One of the biggest obstacles to the widespread adoption of subsurface drip irrigation (SDI) on the High Plains of Texas is the high cost of initial installation. In some cases, SDI costs can be reduced if systems are designed using lower irrigation uniformity standards. The question becomes “what is the cost in terms of cotton lint yield of lowering the uniformity standards for SDI design?” A S...
متن کاملEffect 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...
