Fertilizer Management for Greenhouse Vegetables

Plants require 16 elements for normal growth and reproduction. The objective of a sound fertilizer management program is to supply these required nutrients in ample, but not excessive amounts for optimum crop production. This chapter will present general information on plant nutrition that will...

Growing Greenhouse Cucumbers

1. Cucumbers are considered a quick crop because it only takes about 2 weeks to get a seedling ready for transplanting. Also, after transplanting, it should only take approximately 30 days to begin reaping, with harvest continuing for upwards of 3 months. 2. Cucumber plants need about 8-10...

Irrigation of Greenhouse Vegetables

Vegetables produced in greenhouses require ample amounts of water for optimum growth, yield, and fruit quality. Water is the "universal solvent" in plant cells and is involved in many biochemical processes. Growth processes will slow, and lower yield and quality will result if the plant...

Materials Handling - Florida Greenhouse Vegetable Production Handbook

Chemicals Fertilizer materials should be stored in a separate storage building. Humidity in a greenhouse can lead to hardening and caking of some fertilizer salts. Stock tanks should be covered and located away from electrical controllers and switches. This is especially true if acids are being...

Evaluation of Low-Drift Nozzles in Agrochemical Applications in Orchards

Fruit production demands several phytosanitary treatments per year. The efficiency of these treatments is affected by product loss because of drift, a situation that is aggravated by frequent high winds and the presence of a substantial rural population. The objective of this study was to evaluate...
