This book was released on 1984 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: The experiments was conducted at the Central Experiment Sation at UPLB from November 1983 to Febrary 1984 to evaluate the yield, quality and other agronomic characteristics of Thai DMR Super Sweet corn when grown at different levels and plant density, and harvested at various stages of maturity. A split-plot design was used with two nitrogen levels as main plots, two planting densities as subplots and four harvest dates as sub-sub plots. Each treatment was replicated three times. The results showed that increasing the nitrogen rate from 100 to 200 kg N/ha significantly increase yield of marketable e green corn. Mowever, days to silking, barreness, percentage lodged plants, plant height, ear length and diameter, weight of individual ears, number of marketable ears and total yield were not affected. Increasing the plant population from 53,333 to 88,932 plants/ha increased barreness, lodged plants, desirable green ears and total yield. However, stalk diameter, ear length and weight of marketable ears were decreased. Quality of sweet corn as scored was not significantly affected by rate of nitrogen applied and plant population density. These quality parameters appeared to be more dependent on stage of maturity when the corn ear is harvested for market. Though, ear diameter, weight of individual ear, yeild of marketable green ear and total green ear yield increased as maturity advances, tenderness ans sweerness declined markedly. Higher yield and better quality of procedure can be obtained from Thai DMR Super (...).

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.

This book was released on 2001-12-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen in the Environment: Sources, Problems, and Management is the first volume to provide a holistic perspective and comprehensive treatment of nitrogen from field, to ecosystem, to treatment of urban and rural drinking water supplies, while also including a historical overview, human health impacts and policy considerations. It provides a worldwide perspective on nitrogen and agriculture. Nitrogen is one of the most critical elements required in agricultural systems for the production of crops for feed, food and fiber. The ever-increasing world population requires increasing use of nitrogen in agriculture to supply human needs for dietary protein. Worldwide demand for nitrogen will increase as a direct response to increasing population. Strategies and perspectives are considered to improve nitrogen-use efficiency. Issues of nitrogen in crop and human nutrition, and transport and transformations along the continuum from farm field to ground water, watersheds, streams, rivers, and coastal marine environments are discussed. Described are aerial transport of nitrogen from livestock and agricultural systems and the potential for deposition and impacts. The current status of nitrogen in the environment in selected terrestrial and coastal environments and crop and forest ecosystems and development of emerging technologies to minimize nitrogen impacts on the environment are addressed. The nitrogen cycle provides a framework for assessing broad scale or even global strategies to improve nitrogen use efficiency. Growing human populations are the driving force that requires increased nitrogen inputs. These increasing inputs into the food-production system directly result in increased livestock and human-excretory nitrogen contribution into the environment. The scope of this book is diverse, covering a range of topics and issues from furthering our understanding of nitrogen in the environment to policy considerations at both farm and national scales.

This book was released on 2023-08-25 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen (N) is a mineral nutrient that is essential for the normal growth and development of plants that is required in the highest quantity. It is an element of nucleic acids, proteins, and photosynthetic metabolites, therefore crucial for crop growth and metabolic processes. Recently, it was estimated that N fertilizers could meet the 48% demand of the world’s population. However, overuse and misuse of N fertilizers raised environmental concerns associated with N losses by nitrous oxide (N2O) emissions, ammonia (NH3) volatilization, and nitrate (NO3−) leaching. For instance, NH3 is a pollutant in the atmosphere, N2O is a greenhouse gas that has a warming potential 298 times higher than CO2 and contributes to ozone depletion, and NO3− causes eutrophication of water bodies. Agricultural practices account for about 90% of NH3 and 70% of N2O anthropogenic emissions worldwide. The efficient use of N chemical fertilizers can be attained through cultural and agronomic practices. Nitrogen use efficiency (NUE) is an important trait that has been studied for decades in different crops. The grain production or economic return from the per unit supply of N fertilizer simply explained the NUE. Several definitions were suggested by different researchers. NUE can be defined as the product of N uptake efficiency (NUpE) and N utilization efficiency (NUtE). An increase in NUE increases the yield, biomass, quality, and quantity of crops. N is generally applied as chemical fertilizer to the soil, whereas a small amount is added to some crops like grain legumes through the fixation process. On the other hand, crop plants take N through the root system in the form of nitrate or ammonium which is thereby used in different metabolic processes. A number of studies have been conducted to increase the NUE in different crops and it has been indicated that NUE can be improved by agronomic, physiological, biochemical, breeding as well as molecular approaches. Nitrogen is the main limiting nutrient after carbon, hydrogen, and oxygen for the photosynthetic process, phyto-hormonal and proteomic changes, and the growth-development of plants to complete their lifecycle. Excessive and inefficient use of N fertilizer results in enhanced crop production costs and atmospheric pollution. Atmospheric nitrogen (71%) in the molecular form is not available for the plants. For the world's sustainable food production and atmospheric benefits, there is an urgent need to upgrade nitrogen use efficiency in the agricultural farming system. Nitrogen losses are too high, due to excess amount, low plant population, poor application methods, etc., which can go up to 70% of total available nitrogen. These losses can be minimized up to 15–30% by adopting improved agronomic approaches such as optimal dosage of nitrogen, application of N by using canopy sensors, maintaining plant population, drip fertigation, and legume-based intercropping. Therefore, the major concern of modern days is to save economic resources without sacrificing farm yield as well as the safety of the global environment, i.e. greenhouse gas emissions, ammonium volatilization, and nitrate leaching.

Download or read book Handbook of Maize written by Jeff L. Bennetzen and published by Springer Science & Business Media. This book was released on 2009-01-16 with total page 785 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize is one of the world’s highest value crops, with a multibillion dollar annual contribution to agriculture. The great adaptability and high yields available for maize as a food, feed and forage crop have led to its current production on over 140 million hectares worldwide, with acreage continuing to grow at the expense of other crops. In terms of tons of cereal grain produced worldwide, maize has been number one for many years. Moreover, maize is expanding its contribution to non-food uses, including as a major source of ethanol as a fuel additive or fuel alternative in the US. In addition, maize has been at the center of the transgenic plant controversy, serving as the first food crop with released transgenic varieties. By 2008, maize will have its genome sequence released, providing the sequence of the first average-size plant genome (the four plant genomes that are now sequenced come from unusually tiny genomes) and of the most complex genome sequenced from any organism. Among plant science researchers, maize has the second largest and most productive research community, trailing only the Arabidopsis community in scale and significance. At the applied research and commercial improvement levels, maize has no peers in agriculture, and consists of thousands of contributors worthwhile. A comprehensive book on the biology of maize has not been published. The "Handbook of Maize: the Genetics and Genomics" center on the past, present and future of maize as a model for plant science research and crop improvement. The books include brief, focused chapters from the foremost maize experts and feature a succinct collection of informative images representing the maize germplasm collection.
