Tobacco - Potassium (K) Deficiency

By: Matthew Vann, Josh Henry, Paul Cockson, Brian Whipker Tobacco Nutrient Information

Potassium (K) is one of the three core macronutrients, and consequently, deficiency symptoms manifest relatively quickly in tobacco.

Tobacco - Boron (B) Deficiency

By: Matthew Vann, Josh Henry, Paul Cockson, Brian Whipker Tobacco Nutrient Information

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.

Tobacco - Boron (B) Toxicity

By: Matthew Vann, Josh Henry, Paul Cockson, Brian Whipker Tobacco Nutrient Information

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.

Tobacco - Phosphorus (P) Deficiency

By: Matthew Vann, Josh Henry, Paul Cockson, Brian Whipker Tobacco Nutrient Information

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.

Tobacco - Copper (Cu) Deficiency

By: Matthew Vann, Josh Henry, Paul Cockson, Brian Whipker Tobacco Nutrient Information

Copper (Cu) deficiency is extremely rare, consequently it is not normally seen in field conditions. To help with the diagnosis and treatment of Cu deficiency, we induced Cu stress under controlled greenhouse studies. In NC State University trials, symptoms first developed in the middle part of the plant. The middle region of the leaf developed brown veins, which quickly turned black. The tissue surrounding the veins became chlorotic. Symptoms progress up the plant to the younger leaves.

Tobacco - Zinc (Zn) Deficiency

By: Matthew Vann, Josh Henry, Paul Cockson, Brian Whipker Tobacco Nutrient Information

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.

Pest Management Guidelines for Small Acreage North Carolina Rice Growers

By: Mohammad-Amir Aghaee, Der Holcomb

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.

Chapter 4. Vineyard Site Selection

By: Barclay Poling, Ryan Boyles, Carlos Carpio

Grapes grown in North Carolina are sometimes exposed to unfavorable climatic conditions and biological pests that can reduce crops and injure or kill grapevines. Climatic threats include low winter temperatures, late spring frosts, excessive summer heat, and unpredictable precipitation. Biological pests include fungal pathogens and insects that attack the foliage and fruit of vines, as well as birds, deer, and other wildlife that consume fruit and shoots.Vineyard site selection greatly affects both the frequency and severity of these problems and is one of the most important factors affecting profitability in viticulture.

Forage Conservation: Troubleshooting Hay and Silage Production

By: Miguel Castillo, J. J. Romero Forage Notes

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.

Delineating Agriculture in the High Rock Lake Watershed

By: Deanna Osmond

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.

Chapter 7. Canopy Management

By: Tony Wolf

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.

Chapter 9. Vine Nutrition

By: Tony Wolf

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.

Managing Equipment Traffic to Limit Soil Compaction

By: Carl Crozier, Joshua L. Heitman SoilFacts
