Legumes Of Forage Value: Their Diversity And Priority For Collection In India, E. Roshini Nayar, Anjula Panndey, K. Pradheep, Rita Gupta
IGC Proceedings (1997-2023)
Indian subcontinent is a megacentre of agro-diversity. Legumes have a special place with several native crops and economically important species occurring along forest margins and openings, pastures, grasslands and grazing lands. Several are dual-purpose species for food and feed. However, herbage legumes though major components of grasslands and with a major role in their quality and improvement lack persistence as compared to grasses and their collection, maintenance and conservation assumes importance in the wake of change and loss of habitats of native species and introduction of new germplasm with forage potential. Establishing the correct identity of species is therefore a …
Seed Biology And Yield Of Grain Crops, Dennis B. Egli
Seed Biology And Yield Of Grain Crops, Dennis B. Egli
Plant and Soil Sciences Faculty Book Gallery
Description from CABI (Centre for Agriculture and Biosciences International):
This new edition of an established title examines the determination of grain crop yield from a unique perspective, by concentrating on the influence of the seed itself. As the food supply for an expanding world population is based on grain crops harvested for their seeds, understanding the process of seed growth and its regulation is crucial to our efforts to increase production and meet the needs of that population. Yield of grain crops is determined by their assimilatory processes such as photosynthesis and the biosynthetic processes in the seed, which are …

It has long been concerned how crop water use efficiency (WUE) responds to climate change. Most of existing researches have emphasized the impact of single climate factor but have paid less attention to the effect of developed agronomic measures on crop WUE. Based on the long-term field observations/experiments data, we investigated the changing responses of crop WUE to climate variables (temperature and precipitation) and agronomic practices (fertilization and cropping patterns) in the semi-arid area of northern China (SAC) during two periods, 1983-1999 and 2000-2010 (drier and warmer). Our results suggest that crop WUE was an intrinsical system sensitive to climate …

Legume Cover Crops Are More Beneficial Than Natural Fallows In Minimally Tilled Ugandan Soils, Drake N. Mubiru, Mark S. Coyne
Plant and Soil Sciences Faculty Publications
It is important to establish the various effects of legume cover crops on soil physicochemical properties because they have been considered for use as improved fallows (with shorter rest periods) to enhance development and maintenance of soil productivity. Our objectives were to assess: (i) aboveground dry matter yields of legume cover crops; and (ii) cover crop effects on weed infestation and soil physicochemical properties in a minimum tillage management system. Trials were conducted for 2 yr at Kawanda Agricultural Research Institute and on farmers’ fields in Mbale and Pallisa districts, eastern Uganda. Th e experiment layout was a Randomized Complete …

1990 Kentucky Winter Annual Legume Variety Test, L. M. Lauriault, Norman L. Taylor, Jimmy C. Henning, W. T. Edmonson
Agronomy Notes
Cover crops are often used in Kentucky following the harvest of row crops such as tobacco, corn, and soybeans. Living cover crops can prevent erosion, reduce leaching of nutrients, and supply grazing, green manure, or a plant cover in which to no-till the following spring.
Stubble Losses Of Kentucky Soybeans, Larry J. Grabau, Todd W. Pfeiffer
Stubble Losses Of Kentucky Soybeans, Larry J. Grabau, Todd W. Pfeiffer
Agronomy Notes
Double crop soybeans in Kentucky tend to be shorter than plants from full season plantings. Since lowest pod height is related to plant height, double crop soybeans may be subject to greater harvest losses due to pods remaining below the level at which the combine header is operated. While it would be possible to lower the header closer to the soil to pick up some of those pods, that would slow down harvest and increase the risk of picking up stones and other trash. Although the actual cutting heights used in Kentucky are not known, some producers use combines with …
The Effect Of Three Tillage Systems On Bulk Density And Porosity Of A Pembroke And A Beasley Soil After Three Years, Kenneth L. Wells, John H. Grove
The Effect Of Three Tillage Systems On Bulk Density And Porosity Of A Pembroke And A Beasley Soil After Three Years, Kenneth L. Wells, John H. Grove
Agronomy Notes
Many grain producers in Kentucky use a 3 crop in 2 year rotation of corn followed by small grain-soybeans, and commonly no-till the soybeans and corn in order to intensively use sloping land for continuous grain production. Because of the intensity of machinery traffic in this system, growers are concerned that continuous no-till management may cause compaction, and that such fields may need occasional primary tillage. In order to obtain' information regarding things situation, we conducted a test for 3 years on the farm of' Philip Lyvers, in Marion County, Kentucky, in a field which was being used in a …
Zinc Fertilization Of Corn In Kentucky, W. W. Frye, H. F. Miller, Lloyd W. Murdock, D. E. Peaslee
Zinc Fertilization Of Corn In Kentucky, W. W. Frye, H. F. Miller, Lloyd W. Murdock, D. E. Peaslee
Agronomy Notes
Of the agronomic crops, corn is especially sensitive to zinc deficiency. The major symptom of zinc deficiency in corn is broad white stripes in the leaves at or near the growing point in the early growth stages of the plant. It has been referred to as "white bud" disease because of the characteristic whitish area on one or both sides of the midrib near the base of new leaves. It can be seen as a new leaf unfolds from the whorl. Growth is stunted resulting in shorter than normal internodes. The pith of the stalk may become darkened at the …
Response Of Different Crops To Various Rates Of Furnace Ash Applied As A Soil Amendment, Lloyd W. Murdock, George Everette
Response Of Different Crops To Various Rates Of Furnace Ash Applied As A Soil Amendment, Lloyd W. Murdock, George Everette
Agronomy Notes
Furnace ash from coal fired electrical generating steam plants has increased greatly in the last decade with the increased demand for electricity and increased restrictions on air pollution. The large volumes of ash are presenting disposal and containment problems for management of electrical generating plants. Property adjacent to the generating plants has been exposed to fly ash settling from the smoke stacks and ash over flowing from holding structures. The effects of the material on the land and its production are unknown and concern property owners.
Boron Fertilization Of Corn In Kentucky, Lloyd W. Murdock, Kenneth L. Wells, H. F. Miiller
Boron Fertilization Of Corn In Kentucky, Lloyd W. Murdock, Kenneth L. Wells, H. F. Miiller
Agronomy Notes
The need for use of boron (B) for alfalfa production has been recognized for many years in Kentucky and is presently recommended for general use as an annual topdressing on alfalfa fields. Use of B is also recommended in Kentucky for red clover fields which are to be harvested for seed. In recent years, there has been interest in use of fertilizer B for good corn production in Kentucky. Plant available B is greatly affected by soil pH and decreases with increasing soil pH. Because of this, some states recommend use of B on corn grown on soils with a …
Influence Of Time Of Application Of Nitrogen Fertilizer On Corn Yields, Harold F. Miller, Kenneth Wells, Morris J. Bitzer, G. W. Thomas, R. E. Phillips
Influence Of Time Of Application Of Nitrogen Fertilizer On Corn Yields, Harold F. Miller, Kenneth Wells, Morris J. Bitzer, G. W. Thomas, R. E. Phillips
Agronomy Notes
Soil moisture conditions can have a large effect on crop responses to nitrogen fertilization. Kentucky's usual climatic pattern of periods of heavy rainfall and relatively warm temperatures during the winter and spring seasons influences expected yield responses of corn to applied nitrogen. If nitrogen fertilizer is applied in late winter or early spring, some of it may be lost before the plants have made sufficient growth to take up appreciable quantities. The amount of loss that might be expected will be influenced by the amount of rainfall, temperature, amount of organic matter and drainage of the soil.

Tall Fescue Seed Production In Kentucky, Dennis M. Tekrony, C. J. Kaiser, Warren C. Thompson, Robert C. Buckner
Agronomy Notes
Producing tall fescue seed has traditionally been a profitable venture for many Kentucky farmers. It can still provide additional income if: (1) it is properly managed and fertilized and (2) it is integrated into a total farming program which in most cases includes livestock.
Tips For Small Grain Seeding, Morris J. Bitzer, James H. Herbek, Dennis M. Tekrony
Tips For Small Grain Seeding, Morris J. Bitzer, James H. Herbek, Dennis M. Tekrony
Agronomy Notes
TEST YOUR SOIL AND SUPPLY THE SUGGESTED LIMING AND FERTILIZER MATERIALS.
A soil test is the first step to profitable small grain production. A pH of 6.0 to 6.5 is best, and nitrogen should be applied both in the fall and spring. If your small grains are part of a double cropping system the P and K requirements for both crops should be applied in the fall.
