This book was released on 1983 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: While many spring and winter wheat (Triticum aestivum) varieties have been evaluated for yield characteristics under Utah's conventional dryland cropping systems, little is known about these same varieties under new conservation tillage farming management techniques. Farmers are rapidly adopting various reduced tillage systems and need information regarding proper varieties, fertility practices, weed control, etc. A two year field study, in Box Elder County, Utah on a DeJarnet Gravelly silt loam (Loamy-skeletal, mixed, mesic, Calcic Pachic Haploxeroll) and on a Mendon silt loam (fine-silty, mixed, mesic, Calcic Pachic Argixeroll) examined total dry matter, grain yield, percent protein, kernel weight, kernel volume, and average bushel weight responses to four fertility treatments superimposed upon five spring wheat and four winter wheat varieties. Also compared were one spring wheat variety "Komar" and one winter wheat variety "Weston" in a conventional verses conservation tillage dry land cropping system. Soil moisture and soil temperature (20 em and 10 em, respectively below the soil surface) readings were compared between the conventional and conservation tillage planting systems. The conservation tillage plantings were done with an air-seeding tillage planter and the conventional plantings were done with standard deep-furrow drills. Dry granular fertilizer (27 -12-0-4 sulfur) was applied to both deep furrow and conservation tillage plots with the air-seeder. Rates were 0, 168, 224, 280 kg/ha fertilizer material applied. Significant differences were obtained for all spring wheat varieties. Conservation-tilled "Komar" yielded significant yield increases over conventional tilled "Komar". The opposite held true for "Weston", with the conventional-tilled plots yielding a slightly significant increase in grain over conservation-tillage "Weston". No relative difference in soil water or soil temperature were observed in either variety through time. However, at certain growth stages the differences were clearly discernable. Very little significant differences were established among the winter wheat varieties. Because of heavy infestations of snow mold (Calonectria graminicola) on all winter wheat plots, the true potential yield characteristics of conservation verses conventional tillage remain unproven on these winter wheat varieties.

Download or read book Tillage and Crop Production 2nd Ed written by N.R. Das and published by Scientific Publishers. This book was released on 2017-03-01 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Production of crops is directly connected with tillage systems and this tillage system is also helpful for reduction of cost of crop production. Therefore, cropping system may be regulated with the changes of tillage operations. Now-a-days, zero tillage, minimum tillage, no-tillage paira/utera system, stubble-mulch tillage etc. are in vogue, and as a result, higher crop-production is possible, with low cost, though tillage practices differ from place-to-place and crop-to-crop. With the new ideas and concepts the new book entitled 'Tillage and Crop Production', has been written for the development of agriculture in the country, with thirteen chapters, having part - I. (i) Introduction, (ii) Tillage and tilth, (iii) Types and methods of tillage, (iv) Factors affecting tillage, (v) Tillage implements, (vi) Tillage effects on, (vii) Tillage in relation to crop production, (viii) Tillage vs. irrigation and fertilization, (ix) Tillage for crops, croppings and situations, (x) Tillage, crop production and production economics, (xi) Financial aspect of tillage-crop management, and Part - II. Important information on crop production. The book will be very useful for the undergraduate and postgraduate students of all agricultural universities of the country. This book will also be helpful to all ICAR research institutes and all agricultural departmental farms of all States of the country

Available in PDF, EPUB and Kindle. Book excerpt: From the beginning of agriculture until about 1950, increased food production came almost entirely from expanding the cropland base. Since 1950, however, the yield per unit of land area for major crops has increased dramatically. Much of the increase in yields was because of increased inputs of energy. Between 1950 and 1985, the farm tractor fleet quadrupled, world irrigated area tripled, and use of fertilizer increased ninefold. Between 1950 and 1985, the total energy used in world agriculture increased 6. 9 times. Irrigation played a particularly important role in the rapid increase in food production between 1950 and 1985. The world's irrigated land in 1950 totaled 94 million hectares but increased to 140 million by 1960, to 198 million by 1970, and to 271 million hectares in 1985. However, the current rate of expansion has slowed to less than 1 % per year. The world population continues to increase and agricultural production by the year 2000 will have to be 50 to 60% greater than in 1980 to meet demands. This continued demand for food and fiber, coupled with the sharp decline in the growth rate of irrigation development, means that much of the additional agricultural production in future years must come from cultivated land that is not irrigated. Agricultural production will be expanded in the arid and semiarid regions because these regions make up vast areas in developing countries where populations are rapidly rising.
