In 1998, a trial was established with cultivars ‘Iputj’ and ‘Krupnoplodnaya’ at the Latvia State Institute of Fruit-Growing. A VOEN covering system was installed on part of the orchard in summer 2008. Considerable lowering of the canopy and renewed pruning were carried out throughout the trial. During 2009-2012, sweet cherry growth, yield and fruit quality were monitored. The cover was installed before flowering in each spring and uncovered after harvest. The cultivar ‘Krupnoplodnaya’ had a tendency for faster canopy growth under VOEN. Influence of VOEN cover on total yield was not significant, but had a positive tendency on marketable yield. In 2012, the marketable yield was 85% under VOEN, but only 53% without cover due to high precipitation. The cover decreased fruit decay significantly. Fruits damaged by birds (bird pecks) varied year by year. In the first part of the observation period, many damaged fruits were observed also under VOEN, but later the damage was decreased due to installed bird control devices. The fruits of sweet cherries were larger under cover. A positive effect of cover on amount of soluble solids and phenols in fruits was observed for cultivar ‘Krupnoplodnaya’ in 2011.

North Carolina’s fresh strawberry has a $21.4 million economic value, which is primarily from short-day cultivars in the annual plasticulture system. Organic and off-season day-neutral strawberries have higher prices than the conventional, field-grown strawberries. There have been no published studies on suitable cultivars, transplanting dates, and additional winter protection methods for day-neutral strawberry production in high tunnels in North Carolina. The objective of this study was to examine the effect of low tunnels, planting dates, and cultivars on growth, yield, and season extension potential of day-neutral strawberries in high tunnels. Plugs of day-neutral cultivars Albion and San Andreas were either transplanted in raised beds covered with low tunnels (LT) or without low tunnels (control, NLT), inside high tunnels on the N.C. A&T State University Farm (Greensboro, NC) on two different planting dates, which were 1 Sept. (D1) and 29 Sept. (D2) of 2016, or 9 Sept. (D1) and 10 Oct. (D2) of 2017, respectively. A completely randomized design with split-split plots was used. LT did not significantly affect the total yield and plant phenology, but they promoted the first harvest by a week compared with NLT, which resulted in higher yield during the winter of both years. D1 promoted about 24 days of earlier harvest than D2. ‘Albion’ had an earlier bloom and harvest date (by 1 to 3 weeks and 2 to 3 weeks, respectively) than ‘San Andreas’. Strawberry yield was low in the fall season, but it started to increase from January, peaked in April, and decreased again in May. D1 increased the whole season’s marketable yield of ‘Albion’ (430.3 g/plant), compared with that of ‘San Andreas’ (330.9 g/plant). During the winter, ‘Albion’ had a higher yield than ‘San Andreas’. Our study indicates that LT inside HT might not significantly improve the plant growth, early harvest, or total yield. Planting dates had no consistent effect on yield. It was suggested that ‘Albion’ should be considered for high winter yields, and ‘San Andreas’ be a cultivar with high yields of the entire season in high tunnels.

Abstract A field experiment was conducted in the Amiriyat al-Fallujah district of the Anbar governorate to know the effect of the combination of sulfur and organic fertilizer on the growth and yield of onion, (a local red type), under different plant densities. The experiment included two factors, first: a combination of fertilizing with decomposing Cow’s manure (20 tons.ha-1) and sulfur (50 kg.ha-1), and this factor was distributed as follows (T0: fertilizer recommendation (NPK 100-100-120 kg.ha-1 It is considered a control). T1: cow waste + half of the chemical fertilizer recommendation and T2: fertilizer recommendation + sulfur addition and T3: Cow’s manure + half of the fertilizer recommendation + sulfur addition and T4: double the recommendation of cow manure (40 t.ha-1 + half of the fertilizer recommendation + adding sulfur). The second factor: planting distances (S1:10×10, S2:10×15, and S3:10×20) cm. The distance between plants was fixed 10 cm and the dimensions changed between one line and another. The study was carried out as a factorial experiment with the randomized complete block design (RCBD). The results showed clear significant differences for the two study factors in characteristics of vegetative growth, yield, and the content of total soluble solids, as the T4S3 treatment exceeded by giving it the highest number of tubular blades, leaf area and the highest percentage of sulfur in the leaves, which was positively reflected on the plant yield and percentage the total soluble solids amounted to (16.57 blades.plant-1, 15.97 dm2, 1.70%, 0.64%, 104.50 g, 15.83%), respectively, The treatment of planting distances S1 achieved significant differences in the total yield (90.39 tons.ha-1 and 8.91 kg) respectively compared to plants of treatment S3, which achieved(74.29 tons.ha-1and 5.39 kg).

Field experiments were conducted in 1987 and 1988 to study the effect of lamb’s-quarters (Chenopodium album L.) interference on broccoli (Brassica oleracea L. var. botrytis ’Emperor’) growth and yield. Broccoli growth was initially affected by weed interference at 28–36 d after seeding. Generally, the negative effect of weed interference on broccoli growth increased with increasing weed density and time after seeding. Interference by 15 lamb’s-quarters plants m−2 reduced the biomass of broccoli plants by 71–73% compared to the weed-free control at 57–58 d after seeding. Weed density-crop yield relationship curves showed that one lamb’s-quarters plant m−2 decreased total yield by 18–20% and marketable yield by 22–37%. Lamb’s-quarters reduced the total yield per plot by decreasing the average head weight of broccoli. The number of heads per plot was not affected. Weed interference also reduced the weight of heads classified as marketable (> 10 cm across). However, in 1987 more heads failed to reach a marketable size which resulted in a much smaller marketable yield than in 1988.Key words: Brassica oleracea var. botrytis, broccoli, Chenopodium album L., weed density, weed interference, cole crop

‘Cristalina’ and ‘Skeena’ sweet cherry cultivars (Prunus avium L.) on Gisela 6 (Prunus cerasus × Prunus canescens) rootstock planted in 2005 were maintained since 2006 in a randomly blocked split-split plot experimental design with six blocks of two irrigation frequency main plot treatments within which two cultivar subplots and three soil management sub-subplots were randomly applied. The focus of this study was the growth, yield, and fruit quality response of sweet cherry to water and soil management over three successive fruiting seasons, 2009–11, in a cold climate production area. The final 2 years of the study period were characterized by cool, wet springs resulting in low yield and yield efficiency across all treatments. Soil moisture content (0- to 20-cm depth) during the growing season was often higher in soils that received high-frequency irrigation (HFI) compared with low-frequency irrigation (LFI). HFI and LFI received the same amount of water, but water was applied four times daily in the HFI treatment but every other day in the LFI treatment. Consequently, larger trunk cross-sectional area (TCSA) and higher yield were found on HFI compared with LFI trees. Soil management strategies involving annual bloom time phosphorus (P) fertigation and wood waste mulching did not affect tree vigor and yield. Increased soluble solids concentration (SSC) occurred with LFI. Decreased SSC occurred with delayed harvest maturity in trees receiving P fertigation at bloom. The largest fruit size was correlated for both cultivars with low crop loads ranging from 100 to 200 g fruit/cm2 TCSA. Overall cool, wet spring weather strongly affected annual yield and fruit quality, often overriding cultivar and soil and water management effects.

Industrial tomato is the most important vegetable crop of the Brazilian agribusiness. Few researches have evaluated the tolerance of this crop to saline stress. In this study, the effects of five levels of salinity of the irrigation water (1, 2, 3, 4, and 5 dS m-1) and two equivalent proportions of Na:Ca:Mg (1:1:0.5 and 7:1:0.5) were tested on yield and quality of fruits of industrial tomato, cultivar IPA 6. Seedlings were transplanted in rhizotrons and grown under plastic covering until fruit ripening. Volume of water for daily irrigations was determined by the difference between the applied and drained volume in the previous irrigation. Unitary increase of water salinity above 1 dS m-1 reduced the commercial and total yield by 11.9 and 11.0%, respectively, and increased the concentration of soluble solids and the titratable acidity of the fruits by 13.9 and 9.4%, respectively. The increase of the proportion of sodium reduced the total and marketable yield, the number of marketable fruits and pulp yield. Water of moderate salinity, with low concentration of sodium, can be used in the irrigation of the industrial tomato, without significant yield losses.

The current research aimed 1) at evaluating the effects of three biostimulants (legume-derived protein hydrolysate, PH; plant and seaweed extract, PE and SWE) on yield performance and nutritional quality, mineral profiling, antioxidant activities, lycopene, total phenols and ascorbic acid of greenhouse tomato (Solanum lycopersicum L.) under soil culture and 2) to assess the economic profitability of biostimulant applications. Plants were sprayed four times during the growing cycle with a solution containing 1, 3, and 3 mL·L−1 of PE, SWE, and PH, respectively. Foliar applications of biostimulants improved the early and total marketable yield of fresh tomato. The increase of total yield by PE, SWE, and PH was 11.7%, 6.6% and 7.0%, respectively, in comparison with untreated plants. Legume-derived PH increased lycopene, total soluble solids, and K and Mg contents, thereby increasing the nutritional value of the fruits. The applications of SWE, and to a lesser degree PH, enhanced the Ca concentration in the fruit tissue. Our findings indicated that the three tested biostimulants, although they increased the total production cost, improved the nutrient status and yield performance of the crop to a level resulting in net economic benefits.

The effect of organic mulches and mycorrhizal substrate on growth, yield and quality of Gold Milenium apples on M.9 rootstock. Can. J. Plant Sci. 94: 281–291. A 3-yr study was conducted to evaluate the effects of organic mulches and mycorrhizal substrate on growth and yield of apple cv. Gold Milenium grown on M.9 rootstock. Straw (rye), pine bark, conifer tree sawdust, compost (plant debris), cow manure, peat moss substrate (commercial), and mycorrhiza substrate (Mykoflor®, containing mycorrhizal fungi: Glomus intraradices, G. mosseae, G. etunicatum) were applied in spring of each year. All the applied treatments did not affect significantly the tree growth. Mulches did not have a positive effect on total soluble solids of the fruit and the number of fruits in different size categories. Only sawdust mulch significantly increased the number of fruit in size diameter class of 7.0–7.5 cm compared with the control. The use of mulches affected the concentration of macro- and microelements in leaves, particularly Cu, Fe, Mn and Zn. Mulches positively affected the pH and organic matter content of soil. The best results were observed with the use of the compost, cow manure and the mycorrhizal substrate, where the concentrations of P, K and Mg, most of microelements and soil organic matter were elevated.

Onion (Allium cepa L.) is among the most cultivated vegetable crops in the world. Afghanistan is thought to be the origin as several local and wild varieties are found in different parts of the country. Safid e Paisaye is a local variety grown in central parts of Afghanistan in the Ghorband valley. This variety has long storability and high market demand among restaurants in the region, but little research has been done to increase the quality and its availability to the market to increase its market share in Afghanistan. Conducted under supervision of Amity University Uttar Pradesh, Noida, India, at Agriculture Faculty Research Farm of Kabul University, this investigation looks at plough depth, land preparation methods, and planting date on quality and yield of onion bulb; it also studied other cultural practices including irrigation and fertilization dose and frequency. The parameters studied in this investigation include neck diameter (cm), bulb diameter (cm), neck to bulb ratio, bulb weight (gr), bulb volume (cm3), bulb density (gr/cm3), Total Soluble Solids (TSS) (Brix), firmness (Kg/cm2), marketable yield (MT/Ha), and total yield (MT/Ha). The data revealed that planting date has significant influence on bulb quality and yield of onion. The highest bulb diameter (6.95 cm), bulb weight (121 gr), bulb volume (128 cm3), marketable yield (32.54 MT/Ha), and total yield (34.24 MT/Ha) and the lowest neck to bulb ratio (0.04) were recorded for the first planting date (seed sown in nursery on 10 March - seedlings planted in field on 10 May).

Smoke shows promising results in stimulating germination and vigor. The biologically active butenolide compound isolated from smoke has potential to become a valuable tool in horticulture. ‘Heinz-1370’ tomato (Solanum lycopersicum) seedlings showed a positive response to smoke and were therefore tested with smoke-water and butenolide for growth, yield, and nutritional composition. Smoke-water (1:500, by volume) treatment showed the maximum height, number of leaves, and stem thickness from 57 to 78 days after sowing. The percentage of plants with fruit from 85 to 95 days after sowing was much higher with the application of smoke-water and butenolide solution than in the control. The total number of marketable fruit was significantly greater (P ≤ 0.05) for smoke-water–treated (1:500, by volume) tomato plants (168) than for the control (124). Butenolide and the lower concentration of smoke-water (1:2000, by volume) yielded more fruit, but was not significantly (P ≥ 0.05) different from the control. In spite of achieving a greater number of fruit, smoke treatments did not significantly (P ≤ 0.05) change the size, weight, and nutritional composition (ascorbic acid, β-carotene, lycopene, and total soluble solids) of fruit. The harvest indices of smoke-water– and butenolide-treated plants significantly improved (P ≤ 0.05), suggesting the possible use of smoke technology for tomato cultivation.

Integration of inorganic and organic fertilizer is a very important tool for sustainable production of tomatoes contributing to human health. There were six treatments followed the design of RCBD with three replications to observe the growth, yield and the nutritional quality like lycopene and β-carotene of tomato. Treatments were; F1: Control, F2: Pond sediments-100%, F3:50%F2+50%F6, F4:50% F2+50%F5, F5: soil test based (STB) nitrogen as urea, and F6: vermicompost-100%. Statistically significant variations were found for the plant growth and yield. The highest growth and yield performances were found from the treatment F4. Fruit clusters, fruit numbers and fruit weight per plant were found highest in the treatment F4, whereas the lowest was found in the control. The highest marketable yield of tomato (96.17 t/ha) was obtained from the treatment F4 which was 20%, 29%, 13%, and 41% higher compared to F5, F2, F6, and F1 treatments, respectively. The highest amount of lycopene (67.31 ppm) and β-carotene (53.52 ppm) were found from F4 and F6, respectively, whereas the lowest amount was 42.59 ppm lycopene and 13.85 ppm β-carotene from F5 and F1, respectively. Inorganic and organic fertilizer like pond sediments can be applied for the sustainable production of tomato with friendly environment.
