Abstract:

Few herbicides are available for weed control in vegetable production systems using low-density polyethylene (LDPE) plastic mulch. With the elimination of methyl bromide for pest management and subsequent use of various alternative fumigants, the need for herbicides in vegetable production systems has increased. An experiment was conducted to evaluate tolerance of transplant summer squash and tomato to carfentrazone, flumioxazin, glyphosate, halosulfuron, or paraquat applied to the mulch prior to transplanting. After applying herbicides overtop of the mulch but prior to vegetable transplant, t

Abstract:

Tomato production is severely affected by abiotic stresses (drought, flood, heat, and salt) and causes approximately 70% loss in yield depending on severity and duration of the stress. Drought is the most destructive abiotic stress and tomato is very sensitive to the drought stress, as cultivated tomato lack novel gene(s) for drought stress tolerance. Only 20% of agricultural land worldwide is irrigated, and only 14.51% of that is well-irrigated, while the rest is rain fed. This scenario makes drought very frequent, which restricts the genetically predetermined yield. Primarily, drought distur

Two tomato (Lycopersicon esculentum Mill.) cultivars were grown in two organic and two inorganic media to evaluate the effects upon the levels of Ca, Fe, K, P, and vitamin C in the fruit. 'Platense' tomato was grown in a glasshouse, on sand or peat-perlite (hydroponic substrates) irrigated with a complete solution of macro and microelements, or on 100% vermicompost or 50% vermicompost-50% soil (organic substrates) irrigated with water. Fruit were harvested at physiological maturity, and levels of P, K, Ca, Fe, and vitamin C were determined. Fruit grown on organic substrates contained significa

The SPAD value, the chlorophyll fluorescence and the canopy temperature of the leaves and fruits of tomato hybrid “H1015” were investigated under non-irrigated (I0), deficit irrigated (I50) and well-irrigated (I100) conditions. The aim of the experiments was to show which treatment effect on the examined traits affected photosynthesis, leaf temperature and yield quantity, as well as quality under water scarcity. In the control treatment (I0), the canopy temperature increased, but the SPAD decreased compared to the other two treatments (I50 and I100). Chlorophyll fluorescence produced a fluctua

Abstract Portugal is a major producer of tomatoes for processing. Its export industry now ranks 4th worldwide; before the strongly protectionist European Common Market policy initiated in the early 1970s it ranked 3rd (Table 1). The culture of tomatoes for processing in irrigated areas of Portugal is favored by the dry, warm summer that characterizes Mediterranean climates. In addition the summer in Portugal is not too hot for a good tomato set (Table 2).

Trickle-irrigated soils had lower soil NH4-N, NO3-N, and K and higher Mg concentrations than non-irrigated soils. Soil NH4-N, NO3-N, and Mg concentrations were higher in soils mulched with polyethylene than in soils without mulch. The use of trickle irrigation increased
