“…Accordingly, enhancing the nutritional value of fresh tomatoes and tomato products require frequent investigations to evaluate the influences of agricultural practices, such as the use of fertilizers, organic soil amendments, and the environmental conditions on tomato yield and fruit quality. It was demonstrated that increasing N fertilization under field conditions reduced the fruit vitamin C concentration [4]. This is due to the fact that the high N concentration in the fertilizers favors plant leaf area development, thereby lessening light penetration in the canopy and fruit vitamin C development.…”

Four low-cost organic soil amendments (chicken manure, CM; horse manure, HM; yard water, YW; and sewage sludge, SS) that are generated daily in large amounts, and native bare soil were planted with tomato (Solanum lycopersicum var. Mountain spring) seedlings of 52 days old in raised black plastic-mulch. Each of the 5 treatments was also mixed with biochar to make a total of 10 treatments in a randomized complete block design (RCBD). Results revealed that total fresh weight of tomato fruits collected after three harvests from CM and CM mixed with biochar significantly (P < 0.05) increased, whereas yield obtained from HM was the lowest indicating a positive effect of CM on the growth and yield of tomato. HM increased soil urease activity, while CM and SS increased soil invertase activity. Total marketable tomato yield of biochar amended soils was increased by 63 and 20% in HM and YW treatments, respectively compared to other soil treatments. Ascorbic acid (vitamin C) was greatest in fruits of plants grown in CM amended soil. Results of this investigation may help limited-resource farmers in selecting an affordable soil management practice to enhance crop yield, crop nutritional composition, and soil microbial activity.

“…In this study, the flowering pattern of the CGH BL was not more concentrated than the flowering pattern of 'FL 47'. Although unexpected, this finding may be the result of high N fertilizer rate, which can potentially decrease early yields of tomato and generally delays maturity of fruit crops (Johnson, 2012;Kaniszewski et al, 1987). Plants of CGH tomatoes may be more sensitive to N fertilization than staked-upright tomatoes (Ozores-Hampton et al, 2013a) and the N rate used in the study (319 kg · ha -1 ) may have been higher than adequate for this tomato type.…”

Compact growth habit (CGH) tomatoes (Solanum lycopersicum) are determinate plants with shortened internodes and strong side branching due to the brachytic gene (br) that grow either prostrate or upright as a result of unidentified gene(s). Compact growth habit tomatoes do not require staking, tying, or pruning and can potentially be mechanically harvested, lowering Florida fresh-market tomato production costs. Therefore, the objective of this study was to evaluate the effects of two planting configurations (single and double row) and breeding lines (BLs) on CGH tomato plant growth, flowering pattern, yield, and postharvest fruit quality. Two experiments were conducted in Immokalee, FL, during Spring 2013 and 2014 in a split-plot design with four replications. Planting configurations affected CGH tomato growth at midseason in 2013 but not in 2014; however, in 2014, CGH tomato vines grew outside the beds into the row middles, which is uncommon for this tomato type and undesirable. Plants of CGH tomatoes had a similar flowering pattern to a conventional upright tomato cultivar, which was unexpected. Planting configurations did not affect marketable yields in 2013, but single-row plots produced higher extra-large and total marketable yields at first and total season harvests in 2014. Total season marketable harvests ranged from 26.1 to 53.6 and 29.3 to 45.6 Mg·ha−1 in 2013 and 2014, respectively. Fla 8916 was among the highest yielding BLs, maximizing extra-large and total season marketable yields. Unmarketable fruit ranged from 22% to 31% and 25% to 52% of the total season harvest in 2013 and 2014, respectively, and the most common defects were sunscald, off-shape, catface, and graywall. All CGH evaluated may be suitable for mature-green harvest regarding postharvest fruit quality, although fruit ripening uniformity was of concern in 2014. Average CGH total season marketable yields harvested twice were lower than expected yields of staked-upright tomato cultivars that may be harvested three times, but higher than Florida average yields. However, CGH tomato total production cost can potentially be lower than staked-upright cultivars making CGH tomatoes a viable alternative for the Florida mature-green fresh-market industry to remain sustainable.

“…Analysis of variance did not indicate significant differences among the yield of harvested onion leaves, which was significantly affected by fertilization (Polimag® S) in all years of the study. According to Kaniszewski et al (1987), Rozek (2000), Kolota & Adamczewska-Sowinska (2007a, b), yield of vegetable crops is determined by fertilization. Welsh onions require intensive organic and mineral fertilization at 200 kg ha -1 N, 150 kg ha -1 P 2 O 5 , 175 kg ha -1 K 2 O (Brewster, 2008).…”

Welsh onion (Allium fistulosum L.) is grown in Olsztyn (NE Poland) on an area of 4.0 ha. The habitat conditions in the Warmia region are conducive to growing new Welsh onion varieties as annual crops for selective harvesting. A two-factorial field experiment was conducted in a randomized block design with there replications in the Experimental Garden of the University of Warmia and Mazury in Olsztyn in 2009-2012. Seeds of three Welsh onion cultivars, Long White Ishikura, Parade and Performer were used. The effects of the following experimental factors were determined: Welsh onion cultivars Long White Ishikura, Parade and Performer grown from seedlings; the application of a mixed fertilizer, Polimag® S, at two rates of 0.72 t ha-2 and 1.44 t ha-2 , referred to as 50% and 100% rates. The studied Welsh onion cultivars did not differ significantly with respect to yield, although an increase was noted in the total yield of Welsh onion leaves cv. Performer. Polimag® S applied at a 50% and 100% rate significantly increased the total yield of Welsh onion leaves. However, fertilization rate should not be increased above the 50% level since Welsh onion bulb yields were comparable at 50% and 100% rates of Polimag® S. During three consecutive growing seasons, Welsh onion plants cv. Long White Ishikura were characterized by the highest winter hardiness.
