The research aimed to recognize the optimal level of Inputs used for
vegetables grown under plastic houses in highlands. These vegetables included
cucumber in first and second sowing, green beans, and sweet pepper. To realize
this objective, produ
ction function analysis was used for representative sample
of farmers in the area.
Root rot is considered one of the serious widely spread tomato diseases in
plastic houses culture of Syria. Soil solarization, using transparent polyethylene
(PE) covering, was applied during July and August (١٩٩٤-١٩٩٦) in Tartoos
governorate for
controlling soilborne pathogenic fungi. Results indicated that,
native fungal populations in covered moist soil supplied with or without sulfur
were significantly reduced in comparison with the uncovered treatment.
The objective of the research aimes to estimate the optimum amount of
output to produce from vegetables grown under plastic houses. The vegetables
include tomatoes, green beans, cucumber, hot pepper, and sweet pepper in the
Jordan Valley regions,
However, cost function analysis was used in this
research, average variable cost and marginal cost are derived from total cost
function for each crop in each region.
The optimum amount of out put to produce can be determined by equating
marginal cost with price of product. The break even can be estimate by
equating the price of product with the minimum average variable cost.
