Frost forms on solid objects when the water vapor in the atmosphere changes from its vapor phase to small ice crystals. Frost is not frozen dew. If you see frost than you know that the temperature of the object it is on reached 32°F or lower. However, the air temperature, measured at five feet above ground in the vicinity of this object, is likely several degrees higher. Conversely, not every air temperature recorded at or below 32°F means frost formed on solid objects in the area. In spite of this, the average date of the last spring air temperature of 32°F has traditionally been called the last frost date.

Tobacco plants that are B deficient are stunted very early on in production when compared to healthy plants. Initial symptoms involve a noticeable distortion at the growing point. The youngest leaves will develop kinks and other unusual growth patterns. Additionally, the upper leaves will be very thick and brittle to the touch. It has a very distinct “ridged” feeling compared to healthy plants. Symptoms can progress very quickly once initial symptoms are observed. The distorted terminal bud will quickly become necrotic and may abscise from the plant. The older foliage will often become darker green in coloration and will also become distorted. The leaves will begin to curl downward and will take on a crinkled appearance.

Potassium (K) is one of the three core macronutrients, and consequently, deficiency symptoms manifest relatively quickly in tobacco. Potassium is a mobile element, which means it will translocate from mature tissues to the younger tissues where it is needed. This movement of K from older to younger foliage is what causes deficiency symptoms to develop first on the lower foliage.
In most of the south, sweet corn can be produced from early spring until fall. However, sweet corn does have some specific environmental and cultural needs that must be met for the plant to produce high-marketable yields. Corn is a warm-season crop that requires high temperatures for optimum germination and rapid growth. In general, sweet corn does not tolerate cold weather, and frost will injure sweet corn at any stage of growth. Other stressful climatic conditions, such as drought or flooding, can reduce yields and cause small, deformed ears.

Many farmers and home gardeners have reported damage to vegetable and flower crops after applying horse or livestock manure, compost, hay, or grass clippings to the soil. The symptoms reported include poor seed germination; death of young plants; twisted, cupped, and elongated leaves; misshapen fruit; and reduced yields. These symptoms can be caused by other factors, including diseases, insects, and herbicide drift. Another possibility for the source of these crop injuries should also be considered: the presence of certain herbicides in the manure, compost, hay, or grass clippings applied to the soil.

Most soil compaction from equipment traffic occurs where tires contact soil during the first pass over soil. Farmers can reduce compaction by limiting traffic to interrows that have already been trafficked. The authors report their research on traffic patterns and recommend ways that farmers can manage field traffic to limit soil compaction.
Phosphorus (P) is the second most important nutrient in crop production but is often found in relatively low amounts in native soils. Decades of fertilizer application have led to P enrichment of most North Carolina agricultural soils. Excess soil P that leaves agricultural fields via runoff and drainage can cause algal blooms in water resources that lead to impaired drinking water quality and can limit recreational activities. Maintaining adequate soil P levels for crop growth can reduce P runoff, save money, and protect the environment
Molybdenum (Mo) deficiency has not been reported under field conditions. (Descriptions based on the book, Hunger Signs of Crops, 3rd Edition, edited by H.B. Sprague.) Under controlled greenhouse conditions, tobacco plants are slightly stunted when Mo is limited.

Zinc (Zn) deficiency has not been reported under field conditions. Most of the time, the soil will have enough micros to supplement any gaps in the chosen fertilizer plan. To present a more robust set of data, we induced zinc deficiency under controlled greenhouse studies for accurate diagnosis if the problem should arise. In NC State University trials, ornamental tobacco developed a silver cast to the leaves as the initial symptom of zinc deficiency.
Sulfur (S) deficiency can easily be mistaken for nitrogen (N) deficiency in tobacco. The ability to distinguish between the two is very important to determining a corrective measure.
Although subsurface drip irrigation (SDI) is in its infancy in North Carolina, it is becoming more popular as growers learn of its many benefits, which include increased irrigation efficiency.

High-quality wines — those that command premium prices — can be produced only from high-quality grapes. Grape quality can be defined in various ways, but ripeness and freedom from rots are two of the chief qualities. Producing ripe fruit with minimum rot and maximum varietal character is not easy in North Carolina. As described elsewhere in this publication, the combination of climate, soils, and vine vigor often leads to excessive vegetative growth. For reasons that will be discussed, luxurious vegetative growth can reduce vine fruitfulness, decrease varietal character, degrade other components of fruit quality, and hamper efforts at disease control. Canopy management practices can help alleviate these problems.

This publication discusses the factors involved in selecting cotton varieties and the potential economic impacts of making improper selections.
Boron (B) is an essential element that frequently exhibits deficiency symptoms if it is in limited supply. Growers often apply additional B to avoid deficiencies, but if too much B is applied, there is the risk of B toxicity symptoms developing. Boron toxicities initially appear on the lower, older leaves. Early symptoms of boron toxicity will appear as wrinkling of the lower leaves and interveinal chlorosis along the leaf margin. The wrinkling is most likely caused by the lack of cell expansion when toxic levels of B are present. This wrinkling will develop across the leaf’s surface resulting in leaf deformation. Over time the interveinal chlorosis will move inward and develop over most of the leaf. Cells will rapidly die when excess B is supplied, resulting in necrotic spotting. With advanced symptomology, chlorosis and necrosis will progress up the plant to other leaves.

Solar radiation provides the energy to warm our atmosphere and allow plant growth and animal life to exist on earth. The amount of “possible solar radiation” does not depend on the weather and is constant for a given date from year to year. The variation in “possible solar radiation” by date throughout the year is due to the earth’s axis of rotation, which affects the hours of daylight and the angle (directness) of the sun’s rays. The amount actually received, however, does vary, mainly due to the variation in amount of cloudiness.
This chapter discusses the principles of grapevine dormant pruning, reviews reasons for vine training, and describes systems appropriate for use in North Carolina. Profitable grape production requires that grapevines be managed so that a large area of healthy leaves is exposed to sunlight. Such vines are likely to produce large crops of high-quality fruit each year. Grapevines must be trained and pruned annually to achieve this goal. The training system chosen generally dictates how the vines are pruned. Thus, pruning practices and training systems are discussed together in this chapter.
Grapevines require 16 essential nutrients for normal growth and development (Table 9.1). Carbon, hydrogen, and oxygen are obtained as the roots take in water and as the leaves absorb gases. The remaining nutrients are obtained primarily from the soil. Macronutrients are those used in relatively large quantities by vines; natural macronutrients are often supplemented with applied fertilizers.The micronutrients, although no less essential, are needed in very small quantities. When one or more of these elements is deficient, vines may exhibit foliar deficiency symptoms, reduced growth or crop yield, and greater susceptiblity to winter injury or death. The availability of essential nutrients is therefore critical for optimum vine performance and profitable grape production.

Forages can be conserved in the form of hay, baleage, and silage. It is important to keep in mind that, at best, conserved forages can rarely match the nutritive value of fresh forage. Some losses of highly digestible nutrients start immediately after cutting and are unavoidable. The goal in forage conservation is to focus on minimizing losses.

Grazing management can have profound impact on how forage mixtures develop and persists over time. It is the art and science of grazing management that determines whether a potentially good forage, or mixture of forages, will actually be a good one.
Rice is a minor crop in the state of North Carolina with less than an estimated 2000 acres in the entire state. Unfortunately this means there are very few resources for growers. There are currently no insecticides or herbicides registered for use on rice in the state of North Carolina. Due to legal and liability issues we are not allowed to recommend any brand or chemistries of insecticide or herbicide to be used. Since rice is usually a second or third priority crop behind flowers and vegetables we are tailoring these recommendations in a way where you can grow your crop and receive the maximum yield benefits possible given the circumstances. What follows are a series of cultural and non-chemical controls for weed and pest management.
This publication, chapter 1 of the 2018 Peanut Information handbook, describes the current landscape of peanut production in North Carolina.
Under the proposed High Rock Lake Rules, the Basin Oversight Committee (BOC) is tasked with submitting agricultural information on a yearly basis. Unfortunately, some of this information, such as fertilizer rates, is based on best professional judgment; there are no fertilizer-use statistics that are reliable. In addition, best management practices (BMPs) are only captured if they are cost shared. To obtain a better estimate of agricultural practices, this onetime statistically valid area sampling frame was applied to agricultural fields in the High Rock Lake Watershed in order to collect an agricultural baseline of cropping systems, soil types and currently used best management practices, livestock types and numbers, and producer information.
The use of weather information in crop management and particularly the aspects of disease and insect management is growing at a fast pace. Two things drive this growth. Research has provided the understanding of the weather disease and weather insect interactions and technological advances in meteorology and communications have allowed easier and faster access to weather observations. Also, the relatively low cost of the computer systems that provide the decision support for applying this knowledge to every day operations have made them more affordable and practical.
