To increase productivity, it’s important that growers select sweet corn cultivars adapted to particular growing conditions. The goal of this report is to provide growers, crop advisers, county educators, Extension agents, and specialists with a broad evaluation of different commercial sweet corn hybrids and their performance in different locations of the Southeast U.S.

Stubby-root nematodes, Paratrichodorus minor, are considered an important pest of onions in Georgia. Low to high population densities of this nematode were observed in multiple fields in the Vidalia area causing damage to sweet onions. The most obvious aboveground symptoms of stubby-root nematode nematode infection are poor, stunted growth of onion seedlings. Stubby-root nematodes have a wide host range, including sugar beets, potatoes, corn, cotton, peanuts, wheat, onions, grasses and some other vegetable crops that are commonly grown in Georgia. Fallow crop rotation with non-host cover crops and treating seedbeds with suitable fumigant and non-fumigant nematicides are effective controls for this pest.

Root-knot nematodes are highly adaptable, obligate plant parasites (parasites that cannot reach adulthood without a host) that attack plant roots and establish a prolonged relationship with their hosts. There are three common species of root-knot nematodes known to parasitize watermelon in the U.S.: the southern root-knot, M. incognita, the peanut root-knot, M. arenaria, and the Javanese root-knot, M. javanica. The southern root-knot nematode is ranked first in terms of negative impact on watermelon production, particularly in warm temperate climates. Many watermelon fields in Georgia are infested with one or more species of root-knot nematodes.

This research report presents the results of the 2019 corn, sorghum and summer annual forage performance trials. Trials were conducted at seven locations throughout Georgia, depending on the crop. These included Tifton, Plains, and Midville in the Coastal Plain region, Athens and Griffin in the Piedmont region, Calhoun in the Limestone Valley region, and Blairsville in the Mountain region. Hybrids used for silage were evaluated at Tifton, Athens, Calhoun, and Blairsville.

Fertilization is an important practice of maintaining plant health. The blueberry plant is no exception, but there are important considerations when fertilizing blueberries. The rates, timing, and type of fertilizer should be common knowledge for the grower. In this circular, how to fertilize blueberry plants is described with text, diagrams, and calculations to provide growers, Extension agents, and anyone interested with the knowledge to successfully grow blueberries, from newly established to mature plantings. This publication was written to address commercial growers’ need for a reference to avoid costly mistakes such as over-fertilization, discussing both granular and liquid fertilization.
