AbstractStrawberry (Fragaria x ananassa Duchense ex Rozier) is an important horticultural crop grown in Latvia. The aim of this research was to evaluate some newly introduced strawberry cultivars and perspective hybrids and to evaluate the efficiency of natural calcite leaf fertiliser (Megagreen®) on strawberry fruit quality and spread of pests and diseases. The trial was established in 2012 at Pûre, Tukums Municipality. Cultivars ‘Saint Pierre’, ‘Annapolis’, ’Sonata’, ‘Chambly’, ‘Elegance’, ‘Rumba’, ‘Honeoye’, ‘Senga Sengana’ and two hybrids: 35-1 and 39-1 were included in the investigation. Calcite fertiliser was applied four times per season in 2013 and 2014 by spraying on leaves in concentration 0.5%. Strawberries were grown on two row beds with black plastic mulch and drip irrigation. The evaluation was done for two seasons. Most of the evaluated newly introduced cultivars and hybrids had better fruit quality and resistance to diseases than control cultivars. Cultivars ‘Annapolis’, ’Rumba’, ‘Sonata’, ‘Elegance’, and 39-1 were selected as the most promising related to fruit quality and resistance. The application of calcite fertiliser (Megagreen®) on leaves had no statistically significant effect on strawberry fruit quality and resistance.

Plant growth, yield, fruit quality and fruit performance characteristics were evaluated for transparent (T1)-, white (T2)-, black (T3)-, silver coated black plastic (T4) mulched, organic mulched, (T5) and non-mulched (T6) peppers (var. Cubanelle) under drip irrigation during winter and summer of 1981-82. Values of plant growth parameters, fruit weight, fruit width and length were significantly higher at 5% level during the winter than during the summer in each treatment thus resulting in increased winter pepper yield. T1 plots caused lowest pepper yield at 5% compared to yield of T2, T3, T4, T5 and T6. The percentage of defective peppers was highest at 5% level during the summer than during the winter. Second harvest had highest fruit weight at 5% level in comparison with third and fourth harvests during the winter and summer.

A study was conducted to assess the effect of drip irrigation and plastic mulch on growth and seed yield of Semialata. Two types of plastic mulch (green and silver/black) were tested at three levels of irrigation (120%, 100% and 80%) by drip irrigation and one level (100%) by furrow irrigation. The daily water requirement of Semialata was estimated by the equation ETcrop= ETox crop factor. ETcrop is crop water requirement mm/day. ETo (reference evapotranspiration, mm/day) was calculated by FAO calculator which uses temperature and humidity data. In this experiments there were twelve treatments were considered. The treatments were replicated thrice. The experiment was laid in randomized block design. It was observed that drip irrigation with or without plastic mulch is yielding better results in terms of growth parameters and seed yield as compared to furrow irrigation without plastic mulch. It was also observed that maximum suppression (67.58%) of weeds resulted with drip irrigation and silver/black plastic mulch at 80% level of irrigation.

North Carolina is experiencing a revitalization of the strawberry industry due to the adoption of plasticulture technologies and the California cultivar Chandler, which produces excellent yields and fruit quality on black plastic mulch. With this system, berries can be harvested in just 7 to 8 months after planting. The spring harvest season can last up to 6 weeks in most years. Strawberry plasticulture growers in North Carolina typically experience yields of 17,000 to 18,000 lb/acre (19,054 to 20,174 kg·ha-1). Cash expenses for the system are about $4345/acre ($10,736/ha). The system requires both an overhead sprinkler system for blossom and bud frost/freeze protection, and drip irrigation for supplying water and fertilizer in the prebloom, bloom, and fruiting periods. Sandy loam and clay loam soils are ideal for forming the lo-inch-high (25.4-cm) beds with bedding machines. Usually, 33% of the N, 50% of the K, and all of the P is applied preplant, with the remaining N and K applied through the drip-irrigation system. Problems associated with the plasticulture system include higher initial investment relative to matted-row production, and only one fruiting season is possible with the anthracnose-susceptible `Chandler' in the southeastern United States.

Tomato trials with black plastic mulch, drip irrigation, and fertigation were conducted on a Lily sandy loam soil of medium fertility at Crossville, TN in 1990 and 1991. 'Mountain Pride' tomatoes were fertilized with a broadcast preplant application of 1120 kg ha–1 of 10-4.4-8.3 fertilizer with and without combinations of black plastic mulch and weekly applications of 0.64 cm of water for 12 weeks through drip irrigation. Three black plastic mulch and drip irrigation treatments supplied additional nitrogen and potassium fertilizer through the drip irrigation system. Yields were increased by use of black plastic mulch and by trickle irrigation in 1991. However, additions of fertilizer through drip irrigation had no effect on yields.

From 2006 to 2008, four different production systems and five bell pepper cultivars (Capsicum annuum) with either no resistance (Alliance and Camelot), tolerance (Revolution), or resistance (Paladin and Aristotle) to the crown rot phase of phytophthora blight (Phytophthora capsici) were evaluated for the development of skin separation or “silvering” in fruit at a research facility and four commercial vegetable farms in southern New Jersey. Cultivar, production system, and year, each had a significant effect on the total percentage of fruit with skin separation and marketable yield. The percentage of bell pepper fruit with skin separation was higher in both phytophthora-resistant cultivars compared with the phytophthora-susceptible cultivars across all four production systems. Marketable yield was highest when bell peppers were grown in double rows on raised beds with black plastic mulch and drip irrigation compared with bell peppers grown on single rows on raised beds with black plastic mulch and drip irrigation and bell peppers grown on single rows on raised, bare ground beds with buried drip irrigation. Marketable yields were lowest when bell peppers were grown in single rows on high, ridged beds with overhead irrigation. Results of this study suggest that the development of skin separation or “silvering” in fruit is more closely associated with genotype than type of production system.

Fruit quality of 24 selected strawberry cultivars and selections were evaluated. There were great variations in the contents of soluble solids, titratable acidity, carbohydrates, organic acids, and ascorbic acid among different cultivars, reflecting primary genetic differences. Fructose, glucose, and sucrose were found to be the three major sugars, comprising >65% of the total soluble solids in strawberry. Fruit contained lower sucrose compared to fructose and glucose, whereas leaves contained comparable amounts of fructose, glucose, and sucrose. Citric acid was the major organic acid in strawberries. Strawberries were also rich in ascorbic acid. Leaves were much higher in ascorbic acid than fruit. There appeared to be no correlation between fruit and leaves on carbohydrate, organic acid, and ascorbic acid contents.

Benefit Cost

Two systems of relay-intercropping muskmelons (Cucumis melo L.) with Scotch pine (Pinus sylvestris L.) Christmas trees using black plastic mulch and drip irrigation were evaluated for their potential to improve cash return. Returns ranged from a high of $26,200/ha for plastic mulch-drip irrigation and a selling price of $l.00/melon to a low of $6900/ha for bare ground-drip irrigation and a selling price of $0.40/melon. The benefit-cost index ranged from 24 to 3.4, depending on the system evaluated. Pine growth apparently was impeded by plastic mulch; however, increased yields of melons grown under plastic mulch may offset the slight decrease in pine growth.
