Hybrids written by Donald William Kemper and published by . This book was released on 1971 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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...

Book Synopsis Nitrogen Management, Plant Population and Row Width Studies with Corn by : North Carolina Agricultural Experiment Station
Download or read book Nitrogen Management, Plant Population and Row Width Studies with Corn written by North Carolina Agricultural Experiment Station and published by . This book was released on 1973 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corn yields in the Coastal Plain tended to remain constant at populations of 21,000 and 28,000 plants per acre for both short season and full season hybrids. Yields of full season hybrids on upland Piedmont soils were not greatly increased by using populations greater than 12.000 to 16,000 plants per acre. Yields of full season hybrids were not increased by use of 21-inch rows as compared with 42-inch rows. Yields of short season hybrids were higher in 21-inch rows as compared with 42-inch rows. Short season hybrids used in the row width studies were not as tall and did not have as long leaves as the full season hybrids. Thus planting the smaller hybrids in narrower rows gave better ground cover which probably reduced evaporation. A nitrogen rate of 150 Ibs N per acre was adequate for high corn yields on sandy Coastal Plain soils. Yield increase from a higher nitrogen rate was only obtained with a short season hybrid at 28,000 plants per acre in 21-inch rows when moisture conditions were ideal. Under these conditions 200 Ibs N per acre gave the highest yields. On the Portsmouth soil nitrogen rates of 100 to 150 Ibs per acre were adequate for yields. (...).

Book Synopsis Plant Population and Row Spacing Influence Maximum Corn Yield by : F. D. Whitaker
Download or read book Plant Population and Row Spacing Influence Maximum Corn Yield written by F. D. Whitaker and published by . This book was released on 1969 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted in 1965 and 1966 on a fertile Sharon silt loam near Elsberry. Missouri, to determine the maximum yield response of corn for different levels of plant population and now widths, using two hybrids. Adequate fertilizer and irrigation were applied as needed to limit the study to the above variabels. Analysis of corn leaf and whose-plant samples showed that plant nutrition was nor a variable. Adequate soil water was maintained so that the plants were nor under severe water stress after the seedling stage. Other climatic conditions such as cold, wer periods during the early growing season and above-average temperatures during silking and ear-shoot formation limited the yields to below the maximum potential for this area. It is believed, however, that the differences in yield response to the various treatments are representative. Average grain yields from the Pionner 321 hybrid corn were highest from the 24,000- and 20,000- plants populations and 30-inch row widths. The average yields for the 2 years was 159 bushels per acre both populations.(...).

Book Synopsis Effect of Nitrogen Rates, Row Spacings and Population Densities on Yield and Ear Characteristics of Sweet Corn by : Abdulameir Ali Yassen
Download or read book Effect of Nitrogen Rates, Row Spacings and Population Densities on Yield and Ear Characteristics of Sweet Corn written by Abdulameir Ali Yassen and published by . This book was released on 1985 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The response of sweet corn Zea mays L. var. rugosa (cultivar 'Jubilee') to row spacing, nitrogen and population density at two planting dates was studied in a field experiment at the OSU Vegetable Research Farm in 1984. Variables included two row spacings, 75 cm and 90 cm, three nitrogen rates, 150, 200, 250 kg/ha, and seven plant population densities, 49,400; 55,575; 61,750; 67,925; 74,100; 80,275 and 86,450 plants/ha. Population density showed a greater effect on yield (unhusked total and husked good), number of ears/plant, stalk diameter, ear weight, ear length, usable ear length, ear diameter and tipfilling of ears than did nitrogen rates and row spacing. Effects of row spacings and nitrogen rates were generally not significant. Total unhusked yield and yield of husked good ears increased 16 to 20% for the early planting and 22 to 24% for the late planting as plant density increased from 49,400 to 86,450 plants/ha. Ear weight of the first ear decreased 10% in the early planting and about 15% in the late planting as plant density increased from the lowest to the highest. Although characteristics of second ears were affected by plant population density, their contribution was only 3-16% of the total yield. Longer ears and higher ear weights were associated with the lower plant densities. Stalk diameter was reduced, plants were taller, and average number of ears per plant was reduced at higher densities. No significant interactions between the variables studied in the experiment were observed on any of yield or plant and ear characteristics measured.
