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.
Phosphorus (P) deficiency in tobacco begins as a noticeable stunting when compared to a plant with a sufficient supply of P. Additionally, a P deficient tobacco plant may develop a darker green coloration of the upper foliage. Lower leaves will become chlorotic with a mottling of olive green leaf spots. The initial symptoms appearing on the lower foliage may be attributed to the fact that P is mobile within plant tissues and is translocated from these older leaves to the young developing tissues under periods of low P.
Proper application of pesticides and fertilizers is possible only with a sprayer or spreader that is accurately calibrated.

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.

Maintaining adequate soil P levels for crop growth can reduce P runoff, save money, and protect the environment

Though there are no hard survey numbers to demonstrate, anecdotally a majority of rented farmland in North Carolina is still done on a “handshake.” Such verbal tenancies — not reduced to writing or a term lease — are protected under North Carolina state law. Without written agreement, details of the tenancy — in the event of dispute — would have to be testified in court by the party seeking to either prove the tenancy (the farmer) or terminate the tenancy (landowner). One key detail is often the allocation of rent and renewal of tenancy in the event land is sold or devised to new owners during the crop year. This paper address how such allocation should be handled at the purchase contract stage, and also following death of prior owner.

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.
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.

Vineyard establishment involves careful planning, thorough site preparation, vineyard design, planting, and trellis construction. Unlike dormant pruning or other annual activities, designing and establishing a vineyard must be done correctly the first time. In addition, the process must be tailored to the particular site and the grower’s intentions. This chapter discusses the basic steps in establishing a vineyard and offers suggestions for practical methods and materials.There are many alternatives. Although this chapter may be used as the sole source of information for vineyard establishment, it is advisable to obtain and compare information from additional sources before beginning. References provided here include more detailed information on particular aspects of vineyard establishment, such as trellis construction. It is also helpful to visit existing vineyards to examine their design, compare trellising materials, and discuss plant and row spacing.
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.

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.

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.

This study examined the impact of termination timing on cereal rye biomass across 4 North Carolina locations for 2 growing seasons. Termination times were 4 weeks before and at soybean planting. Biomass samples were collected to determine if delaying termination significantly impacted the biomass achieved by the cereal rye cover. Cereal rye biomass ranged from 1325.4 lbs/acre to 6006.5 lbs/acre across environments and treatments. Delaying termination (Green) resulted in significantly higher cereal rye biomass for only 3 of 8 environments. The remaining 5 environments saw no significant gain in biomass from delaying termination an additional 4 weeks. These results suggest that terminating cereal rye at soybean planting may not be necessary to maximize biomass in our Southeastern climate.

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.

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.
