Field studies were conducted in three Florida locations (Bradenton, Gainesville, and Quincy) during 1998-99 and 1999-2000 to: 1) compare the performance of two transplant systems under diverse MBr alternative programs in 'Chandler' strawberry (Fragaria, xananassa), and 2) determine the efficacy of these treatments on soilborne pest control hi straw...

Vegetables are grown throughout the U.S. on various soil types and in various climates. Irrigation is essential to supplement rainfall in all areas to minimize plant water stress. In the U.S., irrigated vegetable production accounts for about 1.9 million ha or 7.5% of the irrigated area. California, Florida, Idaho, Washington, Texas , Nebraska, Ore...

Tomato (Lycopersicon esculentum Mill.) was grown with drip irrigation on an Arredondo fine sand and on an Orangeburg fine sandy loam to evaluate the effect of N and K time of application on petiole sap, leaf-N and -K concentrations, fruit yield, and to determine N and K sufficiency ranges in leaf tissue. On the sandy soil, N-K at 196-112 kg · ha -1...
Article
Tomatoes (Lycopersicon esculentum Mill.)were grown on an Arredondo fine sandy soil to evaluate the effects of water quantity applied by drip irrigation scheduled by pan evaporation in a 3-year study. Water was applied to polyethylene-mulched tomatoes at 0, 0.25, 0.50, 0.75, and 1.0 times pan evaporation in one application per day. Irrigation was al...

Three irrigation treatments (none, drip, and sprinkler) and eight rowcover treatments were evaluated for their capacity to provide freeze protection for strawberries (Fragaria ×ananassa Duch.) in a split-plot factorial field experiment. The period under study included 20 freeze events, two events with minima of -9.5C and -10.0C. With no freeze prot...

Laboratory studies were conducted to characterize the adsorption-desorption and degradation of thiobencarb in soil. Thiobencarb adsorption on soil was correlated with soil organic carbon (r = 0.97) and values (ml g ⁻¹ ) for the following soils were: Pahokee muck 339, Everglades muck 169, and Immokalee sand 14. The adsorption values (ml g ⁻¹ ) per u...
Article
Laboratory and greenhouse studies were conducted to determine the mobility and bioactivity of thiobencarb on a Pahokee muck, Everglades muck, and Immokalee sand. On all soils > 93% of thiobencarb remained in the upper 1 cm after leaching during unsaturated flow. During saturated flow the retardation factor (R T ) of thiobencarb on an Immokalee sand...
Article
Tomatoes (Lycopersicon esculentum Mill.) were grown on polyethylene-mulched beds of an Arredondo fine sand during two seasons to evaluate the effects of trickle-applied N and/or K, percentages of trickle-applied N and K (50%, 75%, and 100%), and schedules of N and K application on fruit yield, and leaf and shoot N and K concentrations. The daily ir...

Tomatoes (Lycopersicon esculentum Mill.) were grown on polyethylene-mulched beds of an Arrendondo fine sand during two seasons to evaluate the effects of trickle irrigation-applied N and/or K, percentages of trickle-applied nutrient(s) (50%, 75%, and 100%), and schedules of nutrient application (variable, 2% to 12.5% of total amount weekly, or cons...

Additional index words. Lycopersicon esculentum, trickle irriga tion, microirrigation. Abstract. Polyethylene-mulched tomatoes {Lycopersicon es-culentum Mill.) were grown with drip irrigation to evaluate the effects of water quantity, and time of N + K application on fruit production. Water quantities applied were 0, 0.17, 0.34, and 0.50 times pan...
Article
Fertigation is the injection of soluble nutrients into irrigation water to enhance crop production. In combination with micro-irrigation (drip irrigation), this technique forms an efficient method for precisely applying nutrients close to the crop root zone, especially when a polyethylene mulch is used. Vegetables are grown throughout the world on...

... For many decades, pre-plant application of methyl bromide in combination with chloropicrin was the fumigant regime of choice for strawberry growers (Overman and Martin, 1978); however, methyl bromide has now been phased out (Watson et al., 1992). Many alternative soil fumigants have been explored for use in strawberry production in Florida, including various combinations of 1,3-dichloropropene with chloropicrin, metam sodium, metam potassium, dimethyl disulfide, and dazomet (Locascio et al., 1999;Noling, 2002;Kokalis-Burelle, 2003). Problems associated with many alternative soil fumigants include: (1) performance inconsistencies relative to methyl bromide, (2) label restrictions regarding use, (3) the need for personal protection equipment during application, and (4) incompatibility for post-plant nematode management during the growing season. ...
... This shows that there is an increase in adsorption with lesser per cent desorption when related to the organic matter content of the soils. Decrease in the amount of herbicide desorbed from the soil in comparison to that adsorbed, and with successive desorption steps, are referred to as the hysteresis effect (Braverman et al., 1990) The desorption process exhibited pronounced hysterisis in all the soils and for every level of initially adsorbed pyrazosulfuron-ethyl which was subjected to desorption. This is evident from the desorption isotherms corresponding to each initial pyrazosulfuron-ethyl concentration. ...

Many of the fluopyram treated plots (Gilreath et al., 2006), insects and mites (Decou, 1994), as well as oomycete and bacterial diseases (Rebollar-Alviter et al., 2007;Turechek and Peres, 2009). Although there were some minor differences observed between the two different techniques used to monitor plant growth, both techniques generally showed a similar trend. ...
... Squash is a popular vegetable for Egyptian consumers and considered an important economic crop (Refaei et al., 2003). Squash as a vegetable crop is preferred to grow under drip irrigation system, as it is the most efficient irrigation system to use scarce water resources to produce vegetables (Locascio, 2005). In addition to investigate the ability of high levels of drip irrigation system uniformity to reduce the expected negative effect of deficit irrigation on crop production compared to non-recommended levels, the objective of this study is to get the most possible benefit of using deficit irrigation to maximize water productivity of squash. ...
... concentration. This is in contrast to the conventional practice where larger amounts of fertilizers are placed on the soil at the beginning of the season in one or very few split doses (Dangler and Locascio, 1990;Kadam and Karthikeyan, 2006). Many countries have recognized fertigation to usher a second Green Revolution for enhancing productivity (Beard, 2000). ...

... Practices contributing to pre-harvest loss Pre-harvest losses could occur due to the presence or absence of practices ranging from choice of sub-optimal crop varieties and seeds [12,13] for local conditions; sub-optimal planting schedule [14,15]; to inefficient farm management practices regarding use of soil [16], water [17], nutrient [17,18]; and pest control [19]. ...
... Other studies reported a higher yield response (up to 10%) with the combination of pre-plant and fertigated N, compared to pre-plant only [40,41]. Accordingly [42], the combination of 40% pre-plant N and 60% fertigation increased (by up to 40%) in late-season, large and extra-large tomato fruit categories. ...

Polyethylene terephthalate was effective as a thermal insulator, reducing frost damage in citrus trees and grape with a thermal conductivity about 0.29 W m À1 K À1 (Kipnees & Raszewski, 1991). ...
