Investigated the effect of different forms of training system the yield of tomatoes in greenhouses. The study involved the genetic forms of tomatoes with one, two and three trees. The influence of training system on the number of fruits per plant, fruit weight, fruit yield per plant and fruit yield per m2. The highest average yield per plant was achieved by growing tomatoes in the three trees, planting a tree in the form given by the average large fruit, and the highest number of fruits per plant was obtained with the training system with three trees, and the lowest in the training system on a tree. When growing on a tree reaches maturity at the earliest, and larger fruits, and the growing maturation of the two trees is a little later, the fruits are slightly smaller, but higher total yield of tomatoes. Growth on three trees achieved the highest yield, but the fruit is considerably smaller, which reduces their market value.

Tomato is one of the most widely consumed and produced vegetables in Ghana. The low yield of tomatoes in Ghana has resulted in huge importation of the produce from neighboring countries. Good agronomic practices are among the key strategies involved in increasing the yield of horticultural produce. This study seeks to evaluate the response of staking and pruning on tomato fruit yield, quality, and cost of production. To achieve this, a field experiment was conducted to investigate the effect of staking and pruning methods on fruit yield and profitability of tomato (Solanum lycopersicum L.) produced in the northern region of Ghana. Treatments were applied in a randomized complete block design with three replications. Treatments were no pruning + no staking (control), single pole staking (SPS), wire trellis (WT), one-stem pruning (1SP), one-stem pruning + single pole staking (1SP + SPS), one-stem pruning + wire trellis (1SP + WT), two-stem pruning (2SP), two-stem pruning + single pole staking (2SP + SPS), and two-stem pruning + wire trellis (2SP + WT). Results showed that 2SP + WT increased fruit diameter, fruit length, and marketable fruit weight by 52%, 32%, and 69%, respectively, compared to the control. The maximum number and weight of marketable fruits obtained from 2SP + WT increased total fruit yield by 76% compared to the control. In all, the performance of the treatments in terms of yield was in the following order: 2SP + WT > 1SP + WT > SPS > WT > 2SP + SPS > 1SP > 2SP > control. Though 2SP + WT increased production cost by 42%, it greatly increased yield by 69% which resulted in 83% net profit compared to the control. Thus, 2SP + WT could be tested on-farm for possible adoption to increase tomato yield, quality, and profit.

Nine traits of 11 cherry tomato (Solanum lycopersicum L.) var. cerasiforme (Dunal) A. Gray) inbred lines exhibited a wide range of genetic variability. High geno- and phenotypic coefficients of variation were obtained for individual fruit weight (68.16 and 74.23%, respectively) followed by number of fruits/plant (58.8 and 68.34%, respectively). High estimates of heritability, genetic advance and genotypic coefficient of variation for the traits of individual fruit weight, number of fruits and clusters/plant were controlled by additive gene action indicating the possibility of selection to improve these characters. Fruit yield/plant showed low heritability along with low genetic advance and did not show significant and positive correlation with the remaining characters. It indicates that improvement of high yield through selection is difficult, rather hybridization can be effective for improving the fruit yield/plant. Among the lines, CH154 produced the highest number of fruits/plant (291) and highest fruit yield (1.89 kg/plant and 63.4 t/ha) and can be selected for cultivation under Bangladesh condition.

Management Techniques

An experiment was conducted to identify suitable production management techniques for tomato (Solanum lycopersicum L.) cultivation during late winter-pre monsoon season in plains of Nepal. For this, organic mulches (rice straw, dried grass, and rice husk) were compared with SN (shade net) and no-mulch (bare field) condition for tomato yield in 2018 and 2019. The pooled analysis of all observed morphological and yield traits were performed and they differed significantly. Rice husk significantly affected number of fruits per inflorescence though number of inflorescence per plant and flowers per inflorescence were similar among organic mulches. The highest fruit yield per plant (4.44 kg plant-1) was obtained with rice husk, the other mulches and SN were at par but the lowest yield (2.75 kg plant-1) was obtained with no-mulch. Similarly, rice husk mulch contributed to the highest number of fruits per inflorescence (5.22), highest fruit weight (46.58 g) and diameter (4.99 cm).Fruit yield positively and significantly associated with fruit per inflorescence(0.78***), fruit diameter (0.65***) and an average fruit weight (0.56***).Organic mulches significantly (p=0.05) contributed to higher yield (86.01 t ha-1) over SN (76.55 t ha-1).Higher values for total soluble solid, Vitamin C and fruit firmness were observed under rice husk mulching. The result of the present study found rice husk mulching as better option for tomato production as compared to SN and no-mulch condition.

Estimates of heterosis for F1 hybrids over mid and better parent were computed for traits that showed significant differences between genotypes on analysis of variance. Heterosis for yield components and yield was studied using 8x8 half diallel cross in tomato (Solanum lycopersicum L.). The heterosis for yield was generally accompanied by heterosis for yield components. Heterosis for marketable fruit yield per plant ranged from (-63.4%) (P3xP8) to (33.8%) (P6xP8) and (-62.5%) (P3xP8) to (52.6%) (P5xP7), for mid parent and better parent respectively. Significant heterosis over better and mid-parent was observed for all the traits.  Best parent and Mid-parent heterosis (MPH) was highest  and in desirable direction for number of marketable fruit per plant  (29.3%; 29.2%)  in crosses ( P3xP6 for both ) and pericarp thickness  (46.3%; 57.6%) in crosses (P2xP6 and P4xP8), number of fruit cluster per plant (32.8%; 35.9%) in cross (P3xP6 for both), individual fruit weight (36.1%; 41.2%) in cross (P2xP8, P3xP5) and fruit diameter (28.4%; 28.3%) in cross (P3xP5; P2xP6), fruit length (23.07%; 20.4%)  in cross (P2xP6 for both). Out of 28 F1 crosses, positive and desirable heterosis by 10 crosses over better parent and 17 crosses over mid-parent were observed for total fruit density in tomato. An important heterosis both in heterobeltiosis and mid-parent was recorded in marketable fruit yield in ton per hectare. From all the crosses, seven crosses revealed positive from which three crosses are the most important P2xP7 (31%),  P3xP5 (20%) and P3xP6 (54%) in better parent heterosis. Similarly for mid-parent heterosis, only ten crosses out of 28 reveled positive while the rest 18 crosses showed the undesirable direction for marketable fruit yield indicating majority of the hybrids exhibited unfavorable heterotic response and only a few hybrids could be considered for selection.

Plant density and fertilization are key practices for improving the fruit quality and yield of vegetables grown in greenhouses. The experiment was performed to investigate the effects of density and fertilization on the fruit yield and quality, economic efficiency of Solanum lycopersicum L. at Duc Trong district of Lam Dong province. The density (50,000; 33,000; 25.000 plants ha-1) and the fertilizer rates (240N – 100P2O5 – 275K2O; 300N – 125P2O5 – 344K2O; 360N – 150P2O5 – 413K2O kg and 420N – 175P2O5 – 482K2O kg ha-1) were studied in a completely randomised split plot design with three blocks. The fertilizer rate (420N – 175P2O5 – 482K2O kg ha-1) was produced the highest height (562.39 cm), fruit setting rate (69.87%), number of fruit per plant (95.65 fruits), average fruit weight (106.37 g), fruit yield (441.11 tons ha-1) and marketable fruit yield (204.31 tons ha-1). The density (25,000 plants ha-1) gave the highest fruit setting rate (75.35%), number of fruit per plant (94.84 fruits), average fruit weight (113.24 g), individual fruit yield (10.02 kg per plant) and fruit yield (501.17 tons ha-1). The combination of density (25,000 plants ha-1) and fertilizer rate (420N – 175P2O5 – 482K2O kg ha-1) have the highest fruit yield (613.5 tons ha-1), marketable fruit yield (223.91 tons ha-1) and rate of return (2.44). In addition, this combination was the best density and fertilizer level management strategy for greenhouse-grown Lahay 334 tomato cultivar in Lam Dong province, Vietnam.

The investigation was carried out at the Horticulture Research Farm of the B.B.A. University, Lucknow (UP), India during rabi season of 2017-18 and 2018-19 to. Study the correlation coefficient and path analysis in tomato (Solanum lycopersicum L.). The twenty genotypes were evaluated in randomized block design with three replication. Genotypic correlation coefficient was indicated that fruit yield (q ha-1) exhibited highly significant positive correlations with average fruit weight (1.042), fruits per plant (0.996), branches per plant (0.831) and fruits per cluster (0.749). It also registered significant negative correlation with days to 50 % flowering (-0.835). However, phenotypic correlation coefficient indicated that fruit yield (q ha-1) had highly significant positive correlations with fruits per plant (0.977), clusters per plant (0.893), average fruit weight (0.729) whereas, significant negative correlation with days to 50 % flowering (-0.178). Path analysis revealed that the traits like fruit yield kg/plot (1.430) and fruit yield per plant (0.034) exhibited positive direct effects on fruit yield and these traits also recorded positive correlation with yield. This suggested that direct selection based on these traits will be rewarding for crop yield improvement.

Abstract Background More than 50% of the soil in Tigray is deficient in macro essential nutrients. Hence, poor soil chemical fertility is a major challenges for low production of crops like tomato in Hawzen. The aim of this work was to study the effects of N and P rates on the yield and quality of tomato (Solanum lycopersicum L.) in Hawzen, Tigray, Ethiopia. Methods Four different rates of N (0, 69, 138 and 207 kg Nha− 1) and P (0, 46, 69 & 92 kg Pha− 1) were laid out in a randomized complete block design with three replications. Soil analysis were done before executing of the experiment. Data were collected on yield, and fruit quality of tomato. Results The results revealed that plant height, leaf area index, number of primary branches per plant, number of clusters per plant, number of flower clusters, number of fruit per clusters and fruit set were significantly influenced by the main effects of N and P rates. The interaction of N and P rates only had significant effects on marketable, total fruit yield, mean fruit weight, and fruit length. Compared to control, application of 138 kg Nha− 1 and 69 kg Pha− 1 increased mean fruit weight, marketable fruit weight and total fruit yield by 35.9%, 70.5% and 68.4%, respectively. Likewise, the main effects of N and P rates were remarkable on total soluble solids, total sugar, titratable acidity, ascorbic acid, lycopene content, and protein. A significant influence on the P content of tomato was detected due to varied rates of P. fruit N concentration was significantly influenced by rates of N only. Conclusion Application of N and P at rates of 138 and 69 kgha− 1, respectively, showed the highest values in most yield and quality measurements and particularly increased yield by 70.5% as compared to the nil fertilizer application. Therefore, 138 kg Nha− 1 and 69 kg Pha− 1 can be used by producers for better yield and quality of tomato in the area.

Supplemental Pollination

Abstract Buzz-pollinated plants require visitation from vibration producing bee species to elicit full pollen release. Several important food crops are buzz-pollinated including tomato, eggplant, kiwi, and blueberry. Although more than half of all bee species can buzz pollinate, the most commonly deployed supplemental pollinator, Apis mellifera L. (Hymenoptera: Apidae; honey bees), cannot produce vibrations to remove pollen. Here, we provide a list of buzz-pollinated food crops and discuss the extent to which they rely on pollination by vibration-producing bees. We then use the most commonly cultivated of these crops, the tomato, Solanum lycopersicum L. (Solanales: Solanaceae), as a case study to investigate the effect of different pollination treatments on aspects of fruit quality. Following a systematic review of the literature, we statistically analyzed 71 experiments from 24 studies across different geopolitical regions and conducted a meta-analysis on a subset of 21 of these experiments. Our results show that both supplemental pollination by buzz-pollinating bees and open pollination by assemblages of bees, which include buzz pollinators, significantly increase tomato fruit weight compared to a no-pollination control. In contrast, auxin treatment, artificial mechanical vibrations, or supplemental pollination by non-buzz-pollinating bees (including Apis spp.), do not significantly increase fruit weight. Finally, we compare strategies for providing bee pollination in tomato cultivation around the globe and highlight how using buzz-pollinating bees might improve tomato yield, particularly in some geographic regions. We conclude that employing native, wild buzz pollinators can deliver important economic benefits with reduced environmental risks and increased advantages for both developed and emerging economies.

The present study entitled “Bioefficacy study of Bacillus subtilis based biofungicide on leaf spot disease, growth and yield attributes of tomato [Solanum lycopersicum L.] cv. ArkaVikas” was conducted at Vegetable Research Farm, Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during rainy season of 2016-17 in Randomized Block Design (RBD) with three replications. The treatments included foliar spray of chemical fungicide (Copper oxychlooride) and biofungicide (Taegro® and Trichoderma) either alone or in combination. Taegro® is a bacterial biofungicide containing 1×1010 CFU/g (13%w/w) of Bacillus amyloliuefaciens strain FZB24 formulated as WP. A total of 12 characters including disease, growth and yield parameters were studied. Disease parameter included leaf spot disease incidence (%) and disease severity (%) whereas growth and yield parameters included days to 50% flowering, height, number of branches per plant, fruit length (cm), fruit width (cm), number of fruits per plant, average fruit weight (g), number of seed per fruit, fruit yield per plot (kg), fruit yield per hectare (kg) were studied. The biofungicide Taegro exhibited significant potential in reducing the leaf spot in tomato and improving the growth and yield attributes of tomato as compared to control. But combined used of Taegro with standard chemical copper oxychloride gave better result than Taegro alone. As a consequence, this may be used as part of an integrated disease management approach so as to minimizes the use of standard fungicides and also protect the environment from pollution and maintenance of the human health.
