Legumes Of Forage Value: Their Diversity And Priority For Collection In India, E. Roshini Nayar, Anjula Panndey, K. Pradheep, Rita Gupta May 2020

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 …


No Tillage Use For Crop Production In Kentucky Counties In 1998, Gerald R. Haszler Jan 1999

No Tillage Use For Crop Production In Kentucky Counties In 1998, Gerald R. Haszler

Soil Science News and Views

For the past several years, we have reported the status of no~tillage adoption in Kentucky counties. Now, CTICt has published the results for 1998. In 1994, 44% of all crops were produced under no tillage in Kentucky, whereas in 1996, that figure had reached 51 % . In 1997, it dropped to 48% and remains at 48% for 1998. Results for the leading no-till states for 1994, 1996, 1997 and 1998 are shown in Table 1. The percentage of major grain crops (com, soybeans and small grains) grown under no tillage in Kentucky are shown by county in Figure 1. …


No Tillage Use For Crop Production In Kentucky Counties In 1997, G. R. Haszler Jan 1998

No Tillage Use For Crop Production In Kentucky Counties In 1997, G. R. Haszler

Soil Science News and Views

Three years ago (1994) and again last year (1996), we reported the status of no-tillage adoption in Kentucky counties. Now, CTIC has published the results for 1997. As before, Kentucky leads the nation in percent of all crops produced under no tillage, but the percentage has slightly decreased from 1996. In 1994, 44% of all crops were produced under no tillage in Kentucky, whereas in 1996, that figure had reached 51% . It dropped to 48% in 1997. The results for 1994, 1996 and 1997 are shown in Table 1. The percentage of major grain crops (corn, soybeans and small …


No Tillage Use For Crop Production In Kentucky Counties In 1996, Gerald R. Haszler, Grant W. Thomas Jan 1997

No Tillage Use For Crop Production In Kentucky Counties In 1996, Gerald R. Haszler, Grant W. Thomas

Soil Science News and Views

Two years ago, we reported the status of notillage adoption in Kentucky counties in the year 1994. Now, CTIC has published the results for 1996. As before, Kentucky leads the nation in percent of crops produced under no tillage, but the percentage has increased significantly. In 1994, 44% of crops were produced under no tillage in Kentucky, whereas in 1996, that figure had reached 51 %. The results for both 1994 and 1996 are shown in Table 1. It is evident that Kentucky has both maintained first place and has also increased its lead over the other states. The percentage …


Estimated Nutrient Content And Uptake By Kentucky's Crops, Kenneth L. Wells, William O. Thom Jan 1994

Estimated Nutrient Content And Uptake By Kentucky's Crops, Kenneth L. Wells, William O. Thom

Soil Science News and Views

A commonly asked question by crop producers is, "how many pounds of plant nutrients do my crops take up?" While the absolute answer to this varies by yield and soil fertility, useful estimates can be made from research data to enable a producer to have a "ballpark" value for nutrient up-take by some of the major crops of Kentucky. The following tables contain estimates of nitrogen (N), phosphorus (P),and potassium (K) contained in certain crops and the amount of N, phosphate (P2O5), and potash (K,O) taken up by tobacco, corn, soybeans, wheat, alfalfa hay, clover grass …


Fall Application Of Fertilizer, Kenneth L. Wells Oct 1985

Fall Application Of Fertilizer, Kenneth L. Wells

Soil Science News and Views

Fall application of fertilizer offers the advantages of (1) getting a job done which can delay early spring planting, (2) being able to get over fields when they are usually drier and less likely to compact, and (3) more often getting a price break from fertilizer dealers. Several crop-related advantages also apply and are discussed below. In terms of nutrients which can be fall applied, phosphate and potash are well adapted, Both these nutrients react strongly enough with soil to resist overwinter leaching. and the requirements for next year's production can safely be applied in the fall. Fall use of …


Molybdenum Nutrition Of Crops In Kentucky, J. L. Sims Dec 1981

Molybdenum Nutrition Of Crops In Kentucky, J. L. Sims

Soil Science News and Views

Molybdenum (Mo) is one of eight micronutrient elements required for the growth of plants. Research conducted in California nearly 40 years ago established its need for plant growth. Mo deficiencies have been reported throughout the world, especially on acid soils in the United States, Australia, and New Zealand. Generally, the Mo requirement of leguminous crops is greater than for non~legumes, but many non-leguminous field and vegetable crops have responded to additions of fertilizer Mo under severe deficiency conditions. Of all the nutrient elements required by plants for growth, Mo is needed in smallest amounts.


The Status Of Sulfur Fertilization Of Crops In Kentucky, Lloyd W. Murdock Jul 1981

The Status Of Sulfur Fertilization Of Crops In Kentucky, Lloyd W. Murdock

Soil Science News and Views

Sulfur has long been recognized as being essential for the growth of plants and animals due to it being necessary for production of several amino acids. Although regarded as a "secondary" element, it is required by plants in fairly high amounts, very similar to that of phosphorus. Sulfur deficiency symptoms in plants are somewhat similar to those of nitrogen since an overall uniform pale-green leaf color develops. Sulfur deficiencies are often found in crops growing on sandy soils with low organic matter content.


Use Of Plant Analysis, William O. Thom Jun 1981

Use Of Plant Analysis, William O. Thom

Soil Science News and Views

Plant analysis is the laboratory determination of several nutrient elements on a single sample of plant material. In recent years this technique has been more frequently used to diagnose soil fertility problems 0r to monitor soil fertility recommendations on growing crops. Current instrumentation makes it possible to rapidly determine several elements on an extract from a plant sample.
