In this study, in which the effects of different applications of vermicompost on the yield and quality of San Andreas strawberry variety were investigated 15, 30, 45, 60 g vermicompost was applied per plant. First flowering, first and last harvest dates, number of fruits per plant, yield per plant (g/plant), fruit weight (g), fruit flavor, macro and micro nutrient content, organic acid amounts were examined. The results showed that the differences between treatments in yield per plant were statistically significant. The highest total yield per plant was obtained from V45 and V30 applications with 972.8 g and 878.9 g respectively and the lowest yield was obtained from the control application with 384.2 g per plant. The largest fruits were obtained from the V60 (19.5 g) application. It was determined that nitrogen, phosphorus, potassium, magnesium, sulfur, manganese, iron, zinc and boron concentrations in the leaves of strawberry plants fertilized with vermicompost were higher than the control. The highest values in organic acid values were determined in oxalic, propionic, malonic, lactic, fumaric and succinic acids in V60 application (5.62, 11.16, 49.00, 104.98 µg/100 g respectively). It seems that the application of vermicompost fertilizer in strawberry cultivation has a positive effect on yield and quality characteristics.

Evaluations of 30 triploid (seedless) watermelon hybrids were conducted in the Spring 1989 season at Bradenton and Leesburg, Florida. There was considerable variation in relative cultivar yields at the two locations. However, consistency in some cultivars did occur. 'HMX 7924' produced the highest total yield and 'CFREC 88-2' had high total yields at both locations. On the other hand, 'ACX 882322', 'Fengshan No. 1', 'FMX 28', 'Fummy', 'Honeyheart', 'Nova', and 'NVH 4295' produced low total yields at both locations. Average fruit weight was high for 'Ssuper Sweet Brand 5244', 'CFREC 88-4', and 'HMX 7924' whereas 'ACX 882322', 'FMX 28', 'Fengshan No. 1', 'Nova', and 'PSR 49087' produced low average fruit weight. Soluble solids exceeded 11% in all entries at Bradenton whereas two entries were lower than 10% at Leesburg. Several experimental lines out performed the named cultivars suggesting that future introductions will be superior to those already available.

Paulista gherkin is a new gherkin type obtained by crossing Cucumis anguria var. anguria x C. anguria var. longaculeatus. It differs from common gherkin in its fruits and leaves. Elite lines of Paulista gherkin present similar performance for total yield and fruit weight but some have distinctive characteristics, including fruit and leaf attributes. The combination of these characteristics through production of Paulista gherkin hybrids could be an alternative for fruit quality and/or yield improvement. The purpose of the present work was to compare the yield of Paulista gherkin lines and their hybrids grown on a trellis net under field conditions. Four lines and their six single-cross hybrids were evaluated for yield and fruit production using the trellised net production system. Seedlings were produced in polystyrene trays with 128 cells, and transplanted to the middle of 1.20 m wide beds. Plants were trained without pruning on netting having 0.1 x 0.1 m openings. The experiment was conducted in a randomized block design with four replicates and seven plants per plot. Yield was expressed as number of fruits and total weight of fruits per plot. Length, width and fruit flesh thickness were also evaluated, with five samples per plot in two harvesting times. Hybrids and their parental lines were similar in fruit yield and quality. The trellised net was suitable for Paulista gherkin production and provided adequate support to the plants. The trellis technique is suitable to make harvesting easier and to improve fruit quality.

SUMMARYThis study was carried out at Elminia University farm in two years (1978 and 1980) to evaluate the effect of some growth regulators on the production of sweetmelon and muskmelon. It was found that plants treated with some growth regulators were earlier and yielded better than untreated ones, except that in the first trial (1978), the total yield of plants treated with indole acetic acid (IAA) was less than that of the control. The highest early and total yields of both sweetmelon and muskmelon resulted from spraying ethrel on the foliage. Fruit weight and length and flesh thickness were increased by some growth substances compared with the control for both crops. Also, percentage of total soluble solids and ascorbic acid concentration increased markedly as a result of growth-regulator treatments for sweetmelon and muskmelon. Generally, two sprays of ethrel solution produced the most consistent effects on yield and yield quality in the two trials with both sweetmelon and muskmelon.

The effects of summer pruning on the yield and quality of apples (Malus domestica Borkh.) from mature `Rogers McIntosh'/M.7 trees were assessed in 1986-88. Summer pruning from 1 July through 1 Sept. enhanced red coloring and increased the percentage of the crop graded U.S. Extra Fancy. Fruit weight was not altered by summer pruning. Total yield was reduced by summer pruning only in 1 year, however, in no year was the harvested yield reduced. The portion of the crop that was picked in the first harvest was increased by summer pruning. Dormant-pruning time was decreased by summer pruning, and the total time required for pruning was increased only 1 of the 2 years where it was measured. Summer pruning and daminozide treatment significantly increased the estimated net returns.

The effect of dried organic and organomineral fertilizers on the yield and quality of the bush processing tomatoes variety ‘Proton’ were explored in 2005–2006. Field experimental plots were established in Žabčice in the Czech Republic. The following variants of fertilizers were included: Agormin T, Agro, Dvorecký agroferm, farmyard manure, mineral fertilizers and unfertilized control. All plots, except the control, were fertilized with mineral fertilizers on the same nutrients level. Total yield, marketable yield, number of fruits and mean fruit weight were assessed. Total solids, carotenoids, ascorbic acid and nitrates (mg.kg−1 of fresh fruit weight) were analysed in fruits. Fertilizers did not significantly influence total yield and marketable yield. The highest yields were found at Agormin T (7.42 kg . m−2 and 6.73 kg . m−2, respectively), the highest mean fruit weight was found at mineral fertilizers (82.9 g) and Agormin T (82.4 g). Fertilizing with Agro resulted in the highest number of fruits (81.0 pieces . m−2). Dvorecký agroferm significantly increased ascorbic acid content in fruits compared to the control. The highest nitrates content was recorded for the control, the lowest for mineral fertilizers. There was not found significant effect of fertilizers on total solids and carotenoids. All tested dried organic or organomineral fertilizers were shown to be efficient alternatives to traditional farmyard manure. Only Agro significantly decreased ascorbic acid content in comparison to farmyard manure.

Soil Test K

Experiments were conducted in the spring of 1990 at Quincy and Live Oak, Florida and 1991 in Quincy to study the effect of 3 K sources (KCl, K2SO4 and KNO3) and 5 K rates (0, 75, 150, 225 and 300 kg ha-1) of yield of `Sunny' tomatoes. Preplant soil test K values were 37 and 54 ppm in 1990, respectively, and 44 ppm in 1991. These K concentrations are considered medium (36-60) for Florida mineral soils. K source had no effect on yield, fruit weight or percent marketable fruit in all studies. In 1990, total yields, yield of extra large (> 7.0 cm) fruit and percent marketable fruit were increased with application of 75 kg ha-1 of K but there was no further response to applied K at both locations. In 1991, total yield increased with applied K up to 150 kg ha-1 then decreased. Fruit size and percent marketable fruit increase with 75 kg ha-1 of K but no further response occurred. There was no interaction of K source and K rate.

Yield And Quality

One of the major problems of watermelon production is the decrease of fruit yield and quality caused by soil diseases. Soil disinfection with methyl bromide (MB) has been used to prevent fungus attacks; however, its use is being restricted because this substance damages the ozone layer. Searching for new MB alternatives, field experiments were carried out in open field in soils infested with Olpidium bornovanus and melon necrotic spot virus in Colima, Mexico, where watermelons had only been grown previously using soil fumigation with MB. Yield and quality of watermelon cultivar triploid Tri-X 313 grafted on two rootstocks of Cucurbita maxima × Cucurbita moschata (‘RS841’ and ‘Shintosa Camelforce’) were evaluated during 2 consecutive years. Each experiment had five treatments, two of them with nongrafted plants at a density of 3472 plants/ha with and without MB fumigation. The remaining three treatments had grafted plants in nonfumigated soil with plant densities of 2778, 2083, and 1740 plants/ha. The use of watermelon grafted on ‘RS841’ and ‘Shintosa Camelforce’ rootstocks significantly increased the average fruit weight and the total yield of watermelon in soil without the need for MB. Grafting may be considered as an alternative MB fumigation. With the use of grafted watermelon plants, planting density may be reduced by 50%, obtaining higher yields than those obtained from nongrafted plants grown on fumigated soil except for ‘Tri-X 313’ grafted on ‘Shintosa Camelforce’ in 2006–2007. Fruits harvested from grafted plants had higher firmness than those harvested from nongrafted plants without affecting the content of soluble solids.

Onions (Allium cepa) produced in southeastern Georgia's Vidalia-growing region are primarily grown from on-farm produced bareroot transplants, which are usually sown at the end of September. These transplants are pulled midwinter (November to January) and reset to their final spacing. This study was to evaluate sowing date, transplanting date, and variety effect on yield and quality of onions. Beginning in the first week of November, onions can be transplanted until the end of December with reasonable yield and quality. For example, in the 2003–04 season, total yield of onions transplanted on 22 Dec. 2003 did not differ from any onions transplanted on earlier dates in November or December. In the 2004–05 season, onions transplanted on 20 Dec. 2004, had lower total yield than onions transplanted in November, but were not different from onions transplanted on 4 Jan. 2005. The propensity of some varieties to form double bulbs can be reduced with later sowing and transplanting dates. Sowing the first week of October rather than the fourth week of September and transplanting in December rather than November can reduce double bulbs in some varieties.

Prunus Avium L

Three cherry rootstocks were evaluated at Lenswood, South Australia, for their effect on yield and quality of fruit from 4 sweet cherry (Prunus avium L.) varieties. There were no significant differences in total fruit yield, individual fruit weight, proportion of rain-split fruit, or fruit diameter between the seedling Mazzard (P. avium), Mahaleb (P. mahaleb) and Stockton Morello (P. cerasus) rootstocks, with varieties Venus, Stella, Sam and Merton Bigarreau, over 5 years. Yields for rootstocks and varieties followed similar trends over time. In particular, a large reduction in yield occurred in 1988, after a mild winter and unsatisfactory chilling at Lenswood. Although the difference was not statistically significant, Stockton Morello tended to produce fruit of lower weight and smaller diameter than the other rootstocks. In 1989, Stockton Morello produced fruit with a mean weight of 8.9 g, Mazzard 9.68 g, and Mahaleb 9.41 g. The percentages of fruit with a diameter >25 mm were 65, 68 and 51, for Mazzard, Mahaleb and Stockton Morello in the same year. Mahaleb was associated with a greater proportion of rain-split fruit in each year. In 1989, 31% of the total yield of fruit from varieties on Mahaleb was rain-split, compared to 23% on Mazzard and 22% on Stockton Morello. Mean fruit yields in 1989 were about 14 kg/tree for Mahaleb, 11 kg for Mazzard and 12 kg for Stockton Morello; a similar trend occurred in other years. Of the varieties, Sam had least rain-split damage each year, the greatest proportion being 7% in 1987. Venus, an earlier maturing variety, was associated with most rain-split fruit and resulted in 46% damaged fruit in 1989.

This study was carried out to evaluate the yield, total N content in leaves and must composition of grapes from the Cabernet Sauvignon variety subjected to the application of urea and organic compost. Cabernet Sauvignon grapevines in Rosário do Sul, RS, Brazil, in 2008, 2009 and 2010 were subjected to annual application of 40 kg N ha-1 in the form of organic compost and urea, and compared to unfertilized grapevines. In the 2008/09, 2009/10 and 2010/11 crop seasons, leaves were collected for analysis of total N content. At maturation of the grapes, the yield and quality attributes of the must were evaluated. The application of N sources, especially organic compost, increased the N content in the whole leaf at full flowering. Application of organic compost and urea has little effect on grape yield and does not affect the total nutrient content in the must, nor the enological attributes.
