From establishment to ripening, proper irrigation is important at each stage of wheat growth. At Lindsay, we take into account many factors, such as local microclimate, soil type and elevation when designing proper irrigation systems to meet your particular needs. For most varieties, and particularly for high production varieties, early irrigation can produce good yields when soils are deep and have an adequate water-holding capacity and sufficient amount of stored water. Water deficit during the yield formation period results in reduced grain weight and shriveling of grain due to hot, dry, strong winds.
As a corn plant grows, its demand for water rises with increasing leaf area, which reaches a maximum near the tasseling stage. The period of time shortly before pollination through grain fill, when the kernels begin to dent, is a critical period during which adequate moisture is important to corn yield. A high-yielding corn crop requires about 56 cm of water, with a range of 51-64 cms. About 38-41 cms of water is enough to produce a low yield, but that depends on when water is available during the season.
The correct amount of water on your soybean crop is essential for producing high yields. Zimmatic® irrigation systems bring a costeffective solution, alleviating risk when the weather isn’t cooperating. It also gives you more flexibility when it comes to planting, because your timeline is not as affected by nature. Proper irrigation management minimizes yield loss due to crop water stress, optimizes yield per unit of water applied and promotes good management practices. The result is a greater return on investment. Soybean is one of the world’s most important crops and is grown for oil and protein. Present global production is about 176 million tons (160 metric tonnes) over 185 million acres (75 million ha)
