Book Description
Field experiments were conducted in 1969 and 1970 to determine the effects of corn hybrid, rate of applied nitrogen and plant population on nutrient uptake, yield, several yield components and several agronomic characteristics of corn (Zea mays L.). The corn was planted at equidistant intervals with plant spacings ranging from 25,4 to 50.8 on, the range of plant populations was 39,520 to 158,080 plants/ha. Nitrogen was broadcast in 67 kg increments (0 to 538 kg of nitrogen/ha) at planting as ammonium nitrate. The corn hybrids used wereN6 x B14, N31 x N28, N28 x C103, Nebr. 808 and Ner. 501D. Irrigation water was supplied as necessary. Ramrod and atrazine were applied for weed control at the rate of 3.36 and 1.12 kh/ha respectively. The parameters measured include the following: uptake of nitrogen, phosphorus, potassium and sulfur (percentage uptake, uptake/plant and uptake/unit area) and dry matter accumulation at the 6-, 11-leaf and at the silking stage were measured. Crain yield, the number of cars and plants per plot and the number of ears per 100 plants, shelling percentage, dry matter of the graing, car lenght, ear width, 100 kernel weight, grain protein, dates of 50% tassel and 50% silked, and dates of the first and last pollen shed were the measured parameters. Plant height, stalk diameter, leaf area and LAI were measured only in 1969. Lodging, breakage and stripping damage were measured only in 1970 becuase of severe wind damage to the crop. As a result of decreased plant size, the uptake of nutrition...
