The advantages of precision agriculture in the vegetable growing and high value crop sector may accrue to horticulturists especially with respect to meet quality standards and to carry out selective and subsequent harvesting. However, the implementation and use of site-specific sensor technologies has never been adopted for horticultural purposes in the context of nitrogen fertilization suffici...
The conservation of water is crucial to sustainable agricultural production in areas of low rainfall or uneven precipitation distribution. Under such circumstances, drip irrigation methods offer a useful option for economic production of vegetable crops. This preliminary study examined the efficacy and performance of two drip irrigation methods on cucumber and tomato crops grown out of season. ...
Cowpea (Vigna unguiculata L. Walp) is an ancient crop widely known as Lobia, Vegetable crop, Black-eyed peas. used pulse, fodder, vegetable, and green manure crop. It to suffer from many diseases pests. Nematodes cause a severe damage cowpea production leading economic losses. Among the nematodes, root-knot nematodes (Meloidogyne spp.) Farmyard manure, spent mushroom compost, leaf waste of mari...
Reduced and modified tillage (RT) systems (e.g. no-, zone-, strip) represent strategies to reduce soil degradation and erosion and protect water quality. We have shown that zone and deep zone tillage systems can provide the environmental and economic benefits of an RT system for many vegetable crops without the harvest delays or losses observed in straight no-till. Each season, more vegetable g...
Vegetables are essential for well-balanced diets. About 3 billion people in the world are malnourished due to imbalanced diets. Vegetables can contribute to the prevention of malnutrition disorders. Genetic engineering enables vegetable breeders to incorporate desired transgenes into elite cultivars, thereby improving their value considerably. It further offers unique opportunities for improvin...
Production timing is an essential element in fresh vegetable growers’ efforts to maximize profitability and reduce income risks. The present study uses biophysical simulation modeling coupled with a dual crop (tomatoes, sweet corn) whole-farm economic formulation to analyze the effects of growers’ risk aversion levels and price consideration (seasonal or annual price consideration) in expected ...
Tomato (Lycopersicum esculentum L.) is the most popular vegetable world-wide. Tomatoes crop and yield is suffered every year due to number of pathogenic diseases. Such diseases are caused by fungi, bacteria, viruses and nematode, develop through soil-borne, above-ground infections and in some instances are transmitted through insect feeding. Although some general review on the fungal diseases o...
In the U.S., tomatoes are only exceeded by potatoes in economic importance. Among fresh vegetable products, annual per capita consumption of fresh tomatoes is only exceeded by lettuce and potatoes. Consumption of fresh tomatoes has remained fairly constant at around 12.8 pounds for the past 10 years as compared to the consumption of processed tomatoes in the form of ketchup and sauces which has...
In the mid 1980’s, management of Diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), in brassica vegetable crops was at crisis level with spray failures prevalent across the industry in Southern Queensland. Insecticide resistance to synthetic pyrethroids was identified in 1986, and resistance monitoring between 1988 and 1992 showed that problems also existed with carbamates, ...
This paper presents a system for autonomously delivering a quantum of fluid to individual plants in a vegetable crop field, using a fine spray nozzle attached to a manipulator arm on a mobile robot. This can reduce input cost and environmental impact while increasing productivity for applications such as micro-nutrient provision, thinning and weeding. The Ladybird platform is introduced and a p...
