A common problem with hydraulic cylinders is rust and pitting of the cylinder rods. If equipment that incorporates hydraulic cylinders is stored outside with the cylinder rods extended, the rods are exposed to weathering. Eventually, the rods will begin to show specks of rust that develop into pits. Once rusting and pitting occur, the rod will destroy the cylinder seal the next time it is activated.

Many growers pick up plastic mulch but several machines are available for this job. Work at the LSU AgCenter has demonstrated that, in some cases, plastic mulch can be picked up by a hay baler.

The use of plastic mulch is a common practice for nearly all strawberry growers and most vegetable growers. Installing the mulch is easier than it used to be when mulch was installed by hand, but it can be challenging.

The performance of 23 bell pepper varieties were evaluated at the Citrus Research Station, Port Sulphur, LA, Jack Liuzza and Sons Farms, Independence, and at David Ritcher Farms in Sunset, LA.

A seeder can be a tremendous aid in planting a vegetable garden. With it, you can stand and walk along the row pushing a seeder instead of having to make a furrow with a hoe, going back along the row bent over dropping seeds, and then covering and packing the row.

Growing commercial vegetables is different from growing agronomic crops and requires a different approach to equipment. A precision cultural system (PCS) developed by the LSU AgCenter can make commercial vegetable production much easier.

Louisiana growers want a beet variety that matures early with globe-shaped roots 2 to 2-1/2 inches in diameter with good exterior and interior color with tall dark green glossy tops that remain in good condition for an extended period of time.

Louisiana growers want a spinach variety that is early in maturing with dark green, savoy type leaves on a upright growing plant with good vigor that does not bolt. Twenty two spinach varieties were evaluated at the Burden Center in Baton Rouge, La.

Louisiana growers want a carrot variety that makes long tapered roots with good exterior and interior color and produces a high percentage of marketable roots with tall to medium tops.

Twelve onion varieties were planted in replicated plots at the Burden Research Center, Baton Rouge, LA in January of 2008. Plants were obatined from Bland Farms, Glennville, GA, Dixondale Farms, Carrizo Springs, TX and Dietrich Gembler, Knippa, TX. The varietes were evaluated for maturity, yield, bulb size, bulb shape, degree of bolting, degree of double bulbs and tast

This article provides links to sources for plastic mulch layers.

This publication includes information on soil preparation, fertilization, training, pruning, nutrient solutions, pollination, harvesting, marketing, and insect and disease control for greenhouse tomatoes.

The use of plastic mulch is a common practice for strawberry and vegetable growers, but there are two major problems with plastic mulch: it is expensive to install and at some point it has to be removed from the field. Several machines are available that help simplify the removal of the mulch.

When growing carrots for commercial production, it is helpful to run a knife in the soil beside the rows. This breaks up any soil compaction, allowing the carrot roots to grow straight.

There is a wide range of seeder types and models available for direct seeding vegetable crops. Smaller growers typically use the less expensive seeders; larger growers can justify more expensive precision seeders.

Cone guide wheels are the heart of a precision cultural system (PCS). Cone guide wheels allow an implement to follow along a shaped bed with no effort on the part of the tractor driver.

Cultivation is essential for nearly all commercial vegetable crops since herbicide choices are limited and vegetable crops cannot tolerate much weed competition. A basic sweep cultivator can do an excellent job of precision cultivation if set up and equipped properly.

Precision vertical plate seeders are available for planting many vegetable crops. These seeders use a vertical metal plate with the cells (holes) on the edge.

All vegetable seeders require openers, coverers and presswheels to provide a furrow for the seeds and to then cover the seeds and assure proper soil contact. These devices must be matched to the soil type and condition for optimum germination and seedling vigor.

Number of seed/pound, seeding rate/acre, spacing, planting dates, optimum soil temperature range for germination, depth to plant seed, days to germinate, days from planting to harvest begins, approximate time from pollination to market and recommended varieties included.

A key component of a precision cultural system is precision bed shaping. A precisely shaped bed is essential to locate the crop row properly when planting and to provide a basis for guidance of subsequent operations.

A standard sweep cultivator can do an excellent job of cultivating vegetable crops once the plants reach 4-6 inches, but it must run very slowly in small crops (1-2 inches) and has a tendency to throw soil over the crop plants. An alternative is a rotary tiller/cultivator.

A basic sweep cultivator can do an excellent job of cultivating vegetable crops but must be run slowly (1-2 mph) when the crop plants are small. A simple modification to a sweep cultivator allows high-speed cultivation of small vegetable crops.

Vegetable growers have many choices in tractors, ranging from older, smaller tractors to large, new tractors. Many are designed specifically for vegetable work.

Many years of testing at the LSU AgCenter have demonstrated that precision belt seeders deliver the best seed spacing uniformity of any type of vegetable seeder – if the seeds are spherical (round) or nearly so. Belt seeders are versatile and can meter a wide range of seed types and sizes.

Downy mildew is a potentially devastating disease of all cucurbits. Disease symptoms, development, control measures and color photographs of symptoms on pumpkin, cucumber and watermelon are included.

The use of plastic mulch is a common practice for strawberry and vegetable growers, but there are two major problems with plastic mulch: It is expensive to install and at some point it has to be removed from the field. Drawings are available to use in building a mulch collector. This machine allows easier retrieval of the used mulch.

Vacuum seeders are popular among larger commercial vegetable growers. They do a good job of singulating most vegetable seeds. They are especially useful for singulating the oddly shaped seeds that cause problems for most other types of seeders.

BOSSIER CITY – Growing tomatoes in a greenhouse may be less costly in the future.Dr. H.Y. Hanna, an LSU AgCenter scientist working at the Red River Research Station in Bossier City, is studying how spacing between bags that hold the plants affects the amount of heat required to produce tomatoes in greenhouses.

Most commercial vegetable growers apply granular fertilizer in a preplant operation, and many also make sidedress applications of granular fertilizer. An excellent way to apply granular materials in either a broadcast or banding mode is with a pendulum-action spreader.

Bed shapers are available in pan-type and spool-type versions. Spool-type bed shapers are not readily available on a commercial basis, but can easily be constructed. These plans provide designs and dimensions for spool-type bed shapers to fit several row sizes and configurations. The designs can easily be adjusted to accommodate different row sizes or multiple rows.

Bed shapers are available in pan-type and spool-type versions. Pan-type bed shapers are easy to make in a farm shop. These plans will show you how to build one.

Flame weed control can be an effective adjunct to cultivation for some vegetable crops and some weeds. Flame weed control fits especially well in organic operations.

Cucumber beetles (rootworms) are significant insect pests of sweet potatoes in Louisiana. Adults and larvae of these insects feed on sweet potatoes, but larvae are the most damaging. Descriptions of the banded cucumber beetle and the spotted cucumber beetle, as well as management strategies for these insects, are included in this publication. (PDF Format Only)
