“…Corn height and grain yield decrease when plants are subjected to drought stress, when in competition with other plants for resources, or a combination of the two (Eck, 1986;Panahyan-e-Kivi et al, 2012;Aydinsakir et al, 2013;Reid et al, 2014;Soderlund et al, 2014). Water stress at vegetative, silking, or grain fill can have negative impacts on corn yield (Eck, 1986;Soderlund et al, 2014;Benjamin et al, 2015) but the greatest impact is at the vegetative (V1-V12) and silking (R1) stages (Eck, 1986;Soderlund et al, 2014).…”

Corn (Zea mays L.) comprises 95% of the feed grain production in the United States. The area dedicated to corn production in the southeastern United States has increased over the past decade, raising concerns about environmental degradation, and creating a need for more sustainable productions systems. One production system that addresses these concerns is the white clover (Trifolium repens L.) living mulch (LM). Previous research defined a sustainable LM system for corn production, but questions regarding water use efficiency (WUE) of the system remain. In this experiment, soil moisture was monitored in the top 30 cm of the soil, from 0 to 15 and 15 to 30 cm, during the corn growing season in a LM, crimson clover (CC) (Trifolium incarnatum L.), and cereal rye (CR) (Secale cereale L.) cover crops. We found that soil volumetric water content (VWC) was greater in the CR treatment than in the LM throughout the growing season, whereas CC and LM were similar 60 days after planting (DAP). The VWC between corn rows was greater in the CR and CC treatments than the LM in both years of the study. The CC and CR treatments had greater WUE than the LM treatment in both years of the study. The WUE was reduced in cover crop treatments in 2016 compared with 2015, likely due to drought conditions in 2016. These results suggest the LM system may be best suited to regions with high rainfall, soils with high water holding capacity, and/or supplemental irrigation.

“…According to Panahyan-e-Kivi et al [25], those differences between low irrigation frequency and high irrigation frequency were due to drought stress and limitation of water during the growing season which limit plant growth and subsequently affecting the aerial agro-morphological traits such as plant height, petiole formation and number of leaf. But, for the traits such as stem thickness and stem formation, this recent study had shown that those differences would only naturally increased plant development that was not significantly affected by the irrigation frequency.…”
