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.

A sample survey of consumer preferences was conducted in order to determine what characteristics should be given highest priority in a pumpkin (Cucurbita moschata) breeding program for Puerto Rico. A total of 527 people from all regions of the island participated in the survey. Very few preference differences were found due to regions, age groups, sex, or frequency of consumption. Pulp color was the most important characteristic considered when purchasing pumpkin. Most participants preferred an orange-yellow internal color. Skin color was also an important consideration. Respondents strongly preferred a 'pinta' or piebald pumpkin skin. Fruit size was important to many surveyed: most preferred a medium size fruit. Most respondents said they bought pieces rather than whole fruit. Skin type and fruit shape were not important considerations for most respondents. In addition to selection for increased yield, a pumpkin breeding program for Puerto Rico should emphasize selection of genotypes with deep orange-yellow pulp, a 'pinta' skin color and medium-sized fruits.

ABSTRACT The use of dwarf lines to obtain mini-tomato hybrids has provided agronomic and economic benefits. In Brazil, round tomatoes predominate over other varieties. The benefits of using a dwarf parent in round tomato hybrids has yet to be explored, making it important to develop dwarf round tomato lines. Backcrossing is the most suitable method to develop these lines. Evaluation and selection of the dwarf populations can improve the development of such lines. Thus, the aim of this study was to select BC1F2 populations of dwarf round tomatoes with agronomic potential and high-quality fruit. The study was conducted at the Vegetable Experimental Station of the Federal University of Uberlândia (UFU). A randomized block design was used, with 15 treatments and three replicates. The genetic material analyzed consisted of 12 BC1F2 dwarf tomato populations, plus both parents (recurrent and donor) and a commercial hybrid. The characteristics assessed were: average fruit weight (g), total soluble solids (ºBrix), number of locules (locules per fruit-1), fruit shape, pulp thickness (cm), longitudinal (cm) and transverse fruit diameter (cm), internode length (cm) and plant height (cm). The data were submitted to mean testing, multivariate analyses and a selection index. In general, average fruit weight in the dwarf populations increased significantly after the first backcross, with some fruits exhibiting a similar shape to round tomatoes. Selection of the populations UFU-DTOM7, UFU-DTOM10, UFU-DTOM5, UFU-DTOM9, and UFU-DTOM3 resulted in an estimated 6% increase in the number of locules, transverse diameter, TD/LD ratio and average fruit weight. The BC1F2 dwarf populations UFU-DTOM7 and UFU-DTOM10 were the most promising for develop inbred lines with round fruits. Despite the considerable progress achieved in this study, we suggest a second backcross, in order to obtain lines and, posteriorly, hybrids with round fruits and compact plants.

The productivity of tomato is influenced mainly by environmental factors, agronomic practices and cultivar potential. Accordingly, a field experiment was conducted at Mizan-Aman, southern Ethiopia in  2016/ 2017 to evaluate the effect of intra-row spacing (20, 30, 40 and 50 cm) on the performance of three tomato varieties(Fetan, Bishola and Roma VF) with the constant inter-row spacing of 70 cm in completely randomized block design with three replications. Data on crop phenology, growth performance, yield and quality parameters were recorded and subjected to analysis of variance using SAS version-9 software. Results of the study indicated that both intra-row spacing and variety had a significant effect on phenology as well as parameters including; the number of branches, the number of fruit cluster and fruit per plant, fruit weight, total fruit yield, marketable and unmarketable yield and total soluble solids (TSS). However, the number of fruits per cluster, fruit shape index, titratable acidity (TA) and pH were significantly different only among varieties, while plant height was significantly affected by intra-row spacing. Closer spacing enhanced early maturity, while wider intra-row (50 cm) produced a maximum number of branches, cluster and fruits per plant, fruit weight, unmarketable yield and TSS. Generally, 20 and 30 cm intra-row spacing was found to be suitable for the production of maximum total and marketable yield. From the three tomato varieties, Fetan was early maturing with the highest total and marketable yield. The varieties were also significantly different in fruit weight, with the highest value obtained from Bishola followed by Fetan. The outcome of this study revealed that, the intra-row spacing of.30 cm and variety Fetan could be promoted for production in Mizan-Aman and similar agro-ecologies.

Tomato (Solanum lycopersicum L.) is one of the most extensively cultivated horticultural crops in the world. Factors such as yield, size, taste, and lycopene content are important criteria that may impact the selection of tomato cultivars for different production systems. The aim of the current study was to evaluate different slicer and cherry tomato cultivars for production under greenhouse and open field conditions. Three cultivars of slicer (BHN 964, Trust, and Geronimo) and cherry (BHN 268, Favorita, and Sakura) tomatoes were tested using randomized complete block design in 2019 and 2020. Results showed that the performance of tested cultivars differed under greenhouse verses open field conditions. Among cherry tomato cultivars in 2020, BHN 268 and Sakura produced significantly greater yield under open field conditions, while under greenhouse conditions yield of BHN 268 was the lowest. Similarly, cherry tomato fruit size from ‘BHN 268’ and ‘Sakura’ was also significantly greater than ‘Favorita’ under field conditions, whereas under greenhouse conditions, the fruit size of ‘Sakura’ was significantly greater than both ‘BHN 268’ and ‘Favorita’. Among slicer tomato cultivars, BHN 964 produced significantly greater yield and had a greater average fruit size than the other two cultivars under greenhouse conditions in 2020 while, Geronimo produced significantly similar or larger yield and had a similar average fruit size compared with BHN 964 under open field conditions. Tomatoes produced under open field conditions were rated significantly greater for taste compared with those produced under greenhouse conditions. Lycopene content in both slicer and cherry tomato cultivars was influenced by the interaction of production type, cultivars, and harvest time. Therefore, it can be concluded that BHN 964 and Geronimo were the highest in lycopene among slicer tomato cultivars for greenhouse and open field production, respectively. Among cherry tomato cultivars, BHN 268 was the highest in lycopene for open field production and Sakura for greenhouse production. Additionally, open field–produced tomatoes taste better than greenhouse-produced tomatoes, but lycopene content may be constrained for mid- and late-season fruits due to high temperature conditions under open field conditions.

The vigorous behaviour of a rootstock modifies the growth and yield of a plant variety or hybrid, altering the plant nutritional requirements. The purpose of this work was to study four ratios of NO3–/NH4+ (100/0, 92/8, 85/15 and 80/20%) over the growth, leaf anatomy and yield of grafted and ungrafted tomato plants. We used a fully randomised experimental block design with factorial arrangement of 2 × 4 (grafted and ungrafted plants and four ratios of NO3–/NH4+), on eight treatments in total with four replicates each, using Tukey’s mean comparison test (P ≤ 0.05). The rootstock was ‘Silex’ by Fito Seeds, with the ‘El Arrojado’ graft (variety) by Gene Seeds. The graft produced an increase in growth, dry biomass production, stomatal density, trichome number, epidermal cell density, fruits per plant, average fruit weight, fruit size and total soluble solids, in comparison with the ungrafted tomato plants. In most of the assessed variables, the grafted tomato plants gave their best response at an 85/15% NO3–/NH4+ ratio; while the ungrafted plants performed better at a 92/8% NO3–/NH4+ ratio. The response of the grafted plants to the different NO3–/NH4+ ratios suggests that grafting induces tolerance to NH4+.

Soilless growing systems can improve water-use efficiency, especially in closed soilless growing systems. The main purpose of this study was to evaluate the effects of different transplanting conditions, and determine how supplying H2O2 as an oxygen source to the rhizosphere of strawberry plants in a soilless growing system affects plant growth, fruit yield and fruit quality. Strawberry plants (Fragaria x ananassa Duch.) cv. ‘Fortuna’ were cultivated in 12 L pots filled with peat substrate, and maintained under conditions of natural light and temperature. Treated plants were supplied with hydrogen peroxide (H2O2) (H1) and control plants did not receive H2O2 (H0). In terms of the transplanting conditions, the plants were transplanted in October (T1), and either maintained in a culture chamber (T2), or refrigerated (T3), for one month, before being transplanted. A completely randomized block design with two treatment factors (transplanting conditions, and H2O2 treatment) and five replications was established. Then, we determined the fruit per plant, yield per plant (g plant−1), fruit weight (g fruit−1), fruit size (mm), SPAD values, crown number, crown diameter (mm), flower number, firmness (g cm−1), pH, total soluble solid (TSS), titratable acidity (TA) and TSS/TA. During the early crop cycle, there were not significant differences between treatment and the transplanting conditions that significantly affected the fruit weight and fruit size, although T3 produced the highest values. During the late crop cycle, the H2O2 treatment affected fruit per plant, yield per plant (g plant−1), and crown diameter, with H1 producing the highest values. Furthermore, the transplanting conditions affected yield per plant (g plant−1), old SPAD values, crown diameter, firmness, TSS, TA and TSS/TA.

An investigation was carried out at the Department of Horticulture, University of Agricultural Sciences, Bangalore during summer-2017 to study the effect ofvaried levels of nitrogen and phosphorus fertigation on cherry tomato under open field and polyhouse conditions. There were 12 treatment combinations comprising of two growing conditions (open field and polyhouse), three levels of nitrogen (120, 150 and 180 kg N ha-1) and two levels of phosphorus (100 and 120 kg P2O5 ha-1) supplied trough fertigation with recommended potassium (150 kg h-1) as constant which were laid out in Factorial Randomized Complete Block Design with three replications. Result revealed that plant height (384.39 cm), fresh weight per plant (3.00 kg),nitrogen balance index (48.56), total leaf area per plant (6293 cm2), mean fruit weight (15.84 g), TSS content (6.30 ºB) and shelf life (15.66 days) were significantly higher under polyhouse condition with fertigation level of 180:120 kg N:P2O5 ha-1. However, significantly higher yield per hectare (78.16 t), Shelf life (15.66 days) and higher cost benefit ratio (4.81) were observed under open field condition with fertigation level of 150:120 kg N: P2O5 ha-1. Further, it can be concluded from the study that application of 150:120 kg N: P2O5 ha-1 through fertigation under open field condition is profitable during summer season in the Eastern Dry Zone of Karnataka.

Background: Cutleaf groundcherry (Physalis angulata L.) has vitamins that are good for health. There were several genotypes of cutleaf groundcherry that have the potential to be widely cultivation, but information of doses of NPK fertilizer for those genotypes was still limited. The objective of this experiment was to determine the response of cutleaf groundcherry to different rates of NPK fertilizer. Methods: The experiment was conducted May - September 2019 in dry land field. The experiment used a factorial randomized block design with three replications. The first factor was genotypes cutleaf groundcherry (PA 01, PA 02 and PA 03) and the second factor was doses of NPK fertilizer (75, 150 and 225 kg ha-1 NPK). Conclusion: The increased in doses of NPK fertilizer to 225 kg ha-1 NPK increased nutrient uptake, plant growth and fresh fruit weight for each genotype of cutleaf groundcherry. Meanwhile ascorbic acid content increased with a dose of 150 kg ha-1 NPK, but decreased with increased NPK fertilizer rates. The beta-carotene content with 75 kg ha-1 NPK fertilizer was higher than with 150 and 225 kg ha-1 doses. The increase of NPK fertilizer doses otherwise decreases the beta-carotene content for each genotype. Shoot dry weight, fresh fruits weight and ascorbic acid in PA 03 genotype higher than PA 01 and PA 02 genotypes.
