Abstract
This research examines solution to overcome the problems of opposition to growing vegetables under protected cultivation, This particular example was chosen to illustrate several important aspects of greenhouse production and marketing that affect profitability such as high prices of vegetable seeds, high prices of materials used in the sterilisation (methyl bromide gas), high prices of plastics in addition to low quality and short duration of use, etc.The study depended on Bossali protected agriculture unit as example of application to measure the performance and efficiency of production and revenue during the period 1994-2006. Using the traditional system of protected cultivation, compared with a new system of performance and management of production processes, depends on the cultivation of some fruit crops under protected cultivation during the period 2007-2015.The study analysed the structure cost of production per greenhouse also discussed some economic indicators such as: farm gate prices, total revenue, total costs and net return of cucumber and sweet pepper (as example for vegetables) and navel orange and keitt mango (as example for fruits). This enterprise budget illustration indicates a lack of profitability of this greenhouse vegetable enterprise using these particular assumptions regarding cost, price, and total revenue. Results revealed that net return reached 1234, 3466 Egyptian pound (LE)/greenhouse (540 m2) in navel orange and keitt mango respectively during the study period.
Highlights
The total world greenhouse vegetable area is 473,466 hectares (Hickman, 2016)
Productivity efficiency needs use of economic resources in a manner that maximises the production with the least possible cost
The value of plastic was the main cost item (18.25%) of the average production costs which reached about Land preparation (LE)
Summary
The total world greenhouse vegetable area is 473,466 hectares (Hickman, 2016). The Egyptian protected cultivation area is over twenty thousand hectares; about 4,032 hectares cultivated under glass greenhouses; about14.053 hectares cultivated under low plastic tunnels and about 2,037 hectares planted under polyethylene greenhouses. The Egyptian protected cultivation area is over twenty thousand hectares; about 4,032 hectares cultivated under glass greenhouses; about. Cucumbers and peppers representing 91% of the cultivated area under protected cultivation, and most of the production of these crops are marketed locally (MALR, 2013). Monitoring production costs and market prices are critical for greenhouse vegetable crops. In this regard, greenhouse vegetable growers should take into consideration the intricacies of the market in terms of prices at different times of the year as well as the best time to enter the market as these can impact directly on returns to labour, investment and overall profitability (CARDI, 2013). Growers who cannot afford the high initial construction costs of net or plastic houses can grow vegetables under temporary net tunnels
