An investigation was undertaken with a view to observing the performance of newly developed summer tomato hybrids during May 2008 to September 2008 at experimental field of Horticulture Research Centre, BARI, Gazipur. Number of fruits per plant, individual fruit weight, fruit size, etc. was significantly higher when the plants were treated with hormone. Fruit yield per plant was quite high in the hormone treated plant (1.57 kg) compared to untreated plants (0.90 kg). In general, all the hybrids performed better when treated with hormone in respect of yield compared to their corresponding untreated plants. The hybrid WP7 × C- 51 had the highest individual fruit weight (56.0 g) Among the hybrids, HT019 × WP10 had the highest fruit yield per plant (1.87 kg) closely followed by C-11 × WP10 (1.81 kg) when the plants were treated with hormone. The untreated plants of the hybrid lines C-41 × WP8, HT019 × WP10 and C-41 × WP10 produced more than 1.0 kg of fruits per plant. This indicates that there is bright scope of tomato production during summer through with and without hormone application, though application of hormone had positive effect on tomato yield.

Leaf Yield

An experiment to ascertain the influence of fruit size on the yield of fluted pumpkin (Telfairia occidentalis Hook F.) was conducted in 2011 and 2012 at Nsukka. The mature fruits of T. occidentalis were graded into three length groups: large (more than 50 cm), medium (34-50 cm) and small (less than 34 cm). The experiment was laid out in randomized complete block design with six replications. The following data were collected: length of the longest vine, number of leaves/plant, vine diameter, marketable leaf and fruit yield. Data collected were subjected to analysis of variance while Genotype by Genotype x Environment interaction biplot was used to show which-won-where among the groups. Significant means were separated using Fisher’s least significant differences. Medium sized fruits gave the highest marketable leaf yield that was significantly higher than the small sized fruits in both years. Small sized fruits were significantly (p<0.05) lower in total leaf yield, fruit weight/hectare, fruit circumference (33.9 cm) and length (22 cm). The biplot explained 100% of the variation in the fruit sizes. Large sized fruits were the best performer in fruit length, while medium sized fruits performed better in total marketable leaf yield, average fruit weight, number of fruits/hectare and total fruit weight/hectare. The highest Benefit Cost Ratio of 1.2 and 2.6 in 2011 and 2012, respectively were obtained from medium sized fruits Medium sized fruit are recommended in favour of small sized fruit for leaf and fruit production, having higher economic returns.

AbstractA long-term study was conducted to explore the possibility of using traditional rain-fed systems for growing domesticatedZiziphus mauritiana(so-called Pomme du Sahel) in the Sahel. Five varieties, Gola, Ben Gurion, Seb, Umran and Kaithli, were grafted on six rootstocks ofZ.mauritianafrom various agroecological zones of Niger. Trees were planted inside microcatchments at 8 × 8 m spacing. Over a period of six years, the variety Umran gave the highest fruit yield (3600 kg·ha−1) and the lowest fruit yield was documented for variety Seb (1970 kg·ha−1). Individual fruit weight ranged from 25.8 g for ‘Umran’ to 9.5 g for ‘Seb’. The rootstocks had no effect on average fruits yields and fruit size. There was a significant linear correlation between fruit yield and annual rainfall. In a rainy year (680 mm), the average yield of the five varieties was 7580 kg·ha−1. The results of the current study indicate that dry land plantations of Pomme du Sahel can guarantee food security during dry years in the Sahel. However, further studies are required to evaluate the economic feasibility of this system.

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.

The effects of 2 consecutive years of annual defoliation during the harvest season on fruit size, yield, juice quality, leaf size and number were examined in trees of the midseason cultivar `Hamlin' and the late-season cultivar `Valencia' orange [Citrus sinensis (L.) Osb.]. In `Hamlin', removal of up to 50% of the leaves in late November had no effect on fruit yield, fruit number, fruit size, soluble solids yield, juice °Brix, and °Brix to acid ratio of juice the following year. In `Valencia', removal of 50% of the leaves in late March decreased fruit yield and soluble solids yield but did not affect Brix or the Brix to acid ratio of the juice. Leaf size of new flush was reduced by removal of 50% of the leaves in both cultivars but there was little effect on total canopy size. There were no measured effects of removing 25% of leaves from tree canopies. Thus, canopy growth, fruit yield, fruit quality, and leaf size were not negatively impacted when annual defoliations did not exceed 25% of the total canopy leaf area in `Valencia' and `Hamlin' orange trees for two consecutive years. Overall, fruit weight increased linearly with increasing ratio of leaf area to fruit number, suggesting that fruit enlargement can be limited by leaf area.

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.

Segregating Population

Nineteen segregating lines of tomato were evaluated at the Horticulture Research Centre of BARI during winter season of 2008-2009 with a view to developing high yielding virus resistant varieties. Wide variation was observed among the lines in respect of number of fruits per plant (13.5-38.3), individual fruit weight (56.8-162.3g), fruit yield per plant (1.28-2.40 kg), and locule number of fruit (2.0-8.5). The highest number of fruits per plant was observed in the line 14-1-1-1-1, but its corresponding individual fruit weight was only 58.4g. The line 15-3-4-2-1 had the highest individual fruit weight (162.3g). The highest fruit yield was recorded from the line 15-3-4-2-1 (81.6 t/ha), which was closely followed by the line 15-1-2-2-1 (79.5 t/ha). Thirteen genotypes were found free from virus infection up to 60 days after transplanting, while the rest had very low (1.4 - 2.8%) virus incidence. Among the entries, considering yield and virus reaction, the lines, 8-1-3-4-1, 8-1-3-1-1, 8-1-3-2-2, 14-1-1-1-1, 15-3-4-2-1, 15- 1-2-2-1 and 15-1- 2-1-2 were selected for further evaluation and recommendation as varieties.  Keywords: Segregating population; tomato.

Yield Quality

In Sudan's agro-ecological zone, tomato production is constrained by a dearth of high fruit yielding and quality (Solanum lycopersicum [L.]) varieties for cultivation in polyhouse. Exotic and indeterminate tomato genotypes with high fruit yield and quality were evaluated to gain information on variation for fruit yield, quality, shape, and interdependence between traits in Sudan agroecology. The seed was sown during 2018 and 2019. Fruit yield, quality, and phenomic traits were measured. Development, °Brix, and fruit yield responded to microclimate factors in the polyhouse over years. ‘Bruno’ was the best for fruit size and ‘Tofi’ for fruit number. Vine length at flowering, fruits/cluster, days to 50% flowering, and days to first flowering and fruit brix are heritable. The genotype responses suggest the need for stable and to develop high-yielding and quality tomato varieties for protected cultivation in the Sudan agro-ecological zone. Testing stable genotypes in locations could enhance breeding efficiency with respect to genotypic stability. The yield data gained under tropical conditions identified traits of superior genotypes for multiple environment studies and to encourage tomato growers to consider protected cultivation in the tropics.

An experiment was undertaken to identify the suitable mulch paper for different high value vegetables during the winter season of November 2019 to March 2020 at the research farm of Olericulture Division, Horticulture Research Centre, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh. The experiment was randomized complete block design with 3 replications. Three vegetables varieties viz., netted melon, watermelon, cucumber and 3 mulch treatments viz., T1=Silver over black mulch; T2= Black mulch; T3= No mulch were included in this study. Different vegetables responded differently with the changes of mulches irrespective of different characters. Considering relationship between the soil moisture content and fruit number it was clear that fruit number, average fruit weight, fruit length, fruit diameter was strongly related with soil moisture content. The effect of different plastic mulches on fruit weight per plant and yield (t/ha) were significant. Mulching produced higher fruit yield per plant and fruit yield per hectare than for the control, indicating that the mulch had positive effect in generating increased fruit yield. Silver over black plastic mulch produced the highest fruit yield viz., 24.22 t/ha (cucumber), 26.37 t/ha (netted melon), 43.59 t/ha (watermelon) followed by black and no mulches. Obviously, control plot produced the lowest fruit yield.

Rockwool is an excellent growing medium for the hydroponic production of tomato; however, the standard size rockwool blocks [4 × 4 × 2.5 inches (10 × 10 × 6.3 cm) or 3 × 3 × 2.5 inches (7.5 × 7.5 × 6.3 cm)] are expensive. The following experiments were conducted with less expensive minirock wool blocks (MRBs), on rayon polyester material (RPM) as a bench top liner, to reduce the production cost of tomatoes (Lycopersicon esculentum) grown in a limited-cluster, ebb and flood hydroponic cultivation system. Fruit yield for single-cluster plants growing in MRBs [2 × 2 × 1.6 inches (5 × 5 × 4 cm) and 1.6 × 1.6 × 1.6 inches (4 × 4 × 4 cm)] was not significantly different from plants grown in larger sized blocks (3 × 3 × 2.5 inches). When the bench top was lined with RPM, roots penetrated the RPM, and an extensive root mat developed between the RPM and the bench top. The fruit yield from plants on RPM was significantly increased compared to plants without RPM due to increases in fruit size and fruit number. RPM also significantly reduced the incidence of blossom-end rot. In a second experiment, single- and double-cluster plants were grown on RPM. Fruit yield for double-cluster plants was 40% greater than for single-cluster plants due to an increase in fruit number, although the fruit were smaller in size. As in the first experiment, fruit yield for all plants grown in MRBs was not significantly different from plants grown in the larger sized blocks. MRBs and a RPM bench liner are an effective combination in the production of limited-cluster hydroponic tomatoes.

AbstractThe trial was carried out at the Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry in 2013-2015. Cv. ‘Auksis’ was tested on 12 rootstocks: B.396, B.9, M.9, M.26, P 22, P 59, P 61, P 62, P 66, P 67, PB.4, and Pure 1. Accumulation of phenolic compounds depended on fruit yield and average fruit weight. On average, significantly lower concentration among rootstocks occurred when apple trees had abundant yield and fruits were smaller. On average chlorogenic acid constituted 50% and total procyanidins 28% of total phenols in ‘Auksis’ fruits. Flavonoid concentration most depended on rootstock and the highest variation was recorded. More than 50% difference occurred between the highest total flavonoid concentration in apples on PB.4 and the lowest on M.9 rootstocks. Low variability of total procyanidin concentration among rootstocks was observed. Differences between the highest and lowest concentration was 15%. Total concentration of phenolic compounds differed among rootstocks by 29-35% depending on the year. Differences in accumulation of phenolic compounds depended on rootstock genotype but not on yield or fruit weight. PB.4 and P 67 rootstocks had the highest, and M.9, P 62 and M.26 had the lowest concentration of total phenol in ‘Auksis’ fruits
