Turkish Journal of Agriculture and Forestry

In order to determine the fertility of soil and nutritional status of strawberry plants grown in the districts of Anamur and silifke, 24 soil and 37 plant samples were collected and analysed. According to the results, 33% of Anamur soils showed high salinity. However, almost all the soils from Silifke showed a non-saline character. Organic matter deficiency was detected in 25% and 67% of the soils of Anamur and silifke, respectively. Approximately 10% of soils in Anamur showed nitrogen deficiency. Both of the districts have suffered available P deficiency, but it is more serious in Silifke. In Anamur, K deficiency …

The Effects Of Shoot Tip Source On The Success Of In Vitro Micrografting In Grapevine (Vitis Vinifera L.), Ni̇lgün Göktürk Baydar, Hasan Çeli̇k

Turkish Journal of Agriculture and Forestry

In this experiment, the effects of the shoot tip source on the success of in vitro micrografting in grapevine were investigated. Shoot tip meristems of Kalecik karası, Emir, Uslu, Hafızali and Razakı grape cultivars were micrografted onto the seedlings of Kober 5 BB. Shoot tip meristems were excised from either in vivo (shoots from actively growing vine in the vineyard and shoots flushed from one year-old cuttings in the greenhouse) or in vitro (shoots obtained by shoot-tip culture in aseptic conditions) sources. Plantlets micrografted on top of the decapitated seedlings were cultured in solid MS medium for two months. Consequently, …

G99-1385 Common Stalk Rot Diseases Of Corn, James Stack

University of Nebraska-Lincoln Extension: Historical Materials

Corn stalk rot diseases occur every year in every field to some extent. This NebGuide discusses the symptoms, impacts and management of these diseases.

Corn is grown throughout Nebraska on over 8 million acres of land; approximately 5 million acres are irrigated. Seed corn, field corn and specialty corns (e.g., high oil, high amylose and white corn) comprise the three main corn production systems. Field corn is grown on the most acreage. Whether grown in an irrigated or dryland production system, all corn hybrids are susceptible to a variety of stalk rot diseases. These diseases occur every year in every …

G99-1393 Grazing Alfalfa, Jerry D. Volesky, Bruce Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Grazing alfalfa may be a cost efficient means of harvest for some producers. This NebGuide explores alfalfa and alfalfa/grass options, varieties and stand establishment, and grazing and bloat management.

Alfalfa is the most productive and versatile forage legume grown in Nebraska. Cutting for hay or silage has been the traditional method of harvest, but many opportunities and options exist for grazing. With current technology and proper management, beef gain can exceed 1,000 pounds per acre with acceptable stand persistence.

G99-1390 Altering Swine Manure By Diet Modification, Duane Reese, Richard K. Koelsch

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explores options for altering the nitrogen and phosphorus content of swine manure.

There are situations in which it is necessary to change the nutrient content and/or the odor-producing potential of swine manure in order for pork production to thrive. For example, current Nebraska Department of Environmental Quality (NDEQ) permit procedures for livestock facilities require producers to document that sufficient land is available for crop use of the nitrogen (N) in manure. If sufficient land is not available for managing nutrients in manure, producers can alter the nitrogen and phosphorus content of swine manure by modifying the pig's diet. …

G99-1389 Cultural Practices To Improve Weed Control In Winter Wheat, Gail A. Wicks, Alex Martin, Drew J. Lyon

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains the influence of cultural practices on weeds in winter wheat. Precipitation and temperature greatly influence crop and weed growth in the semiarid areas of the central Great Plains. Precipitation in Nebraska varies from 14 to 24 inches where fallow is practiced. The purpose of fallow is to control weeds and, when not cropping a field, to store water and stabilize winter wheat fields. With good prewheat-fallow techniques, sufficient soil moisture is usually available to establish winter wheat. Peak rainfall occurs in May and June during the pollination and grain-filling period of winter wheat. The latter part of …

Ec99-1877 Damping Off, Root Rots, And Vascular Disorders Of Soybean, Loren J. Giesler

University of Nebraska-Lincoln Extension: Historical Materials

Soybeans are grown on nearly 4 million acres in Nebraska and are threatened by several diseases, soil-borne fungal diseases being the most common (for growers in the Midwest). Early season damping off and root rots often are followed by premature death, which in many instances is attributed to fungal infections earlier in the growing season causing root and cortical rots and vascular disorders.

This extension circular discusses these diseases, their symptoms and control.
