Sixteen exotic and indigenous cucumber genotypes (Cucumis sativus L.) were evaluated under early and late seasons planting. This was to characterize the cucumber genotypes based on their performance in the derived savannah of Southeast Nigeria agro-ecological zone and estimate character association and contribution towards total fruit yield per hectare. The vegetative traits, such as vine length, number of branches, number of leaves and leaf area were measured at 8 weeks after planting. The phonological traits measured were: days to flower initiation and days to 50% flowering. The reproductive traits like number of staminate flowers per plant, number of pistillate flowers per plant, fruit length, fruit girth, fruit weight per plant, number of fruits per plant, average fruit weight and total fruit yield per hectare were also recorded. Obtained data was subjected to analysis of variance in randomized complete block design and path analysis. The results showed a highly significant difference (p<0.01) among the genotypes in all the traits studied in both seasons. ‘Beit Alpha’ genotype gave the highest fruit yield/ha in early season planting, while in the late season, the highest yield producer was ‘Ashely’. In both seasons, vine length, number of branches and leaves, leaf area, number of pistillate and staminate flowers/plant, number of fruit and fruit weight/plant showed positive and significant correlation with total fruit yield/ha. In both seasons, the highest positive direct effect on yield was recorded in fruit weight/plant. Significantly (p<0.05), the highest total fruit yield/ha was recorded in the early rainy season planting in this agro ecological zone. Based on high fruit yield, ‘Beit Alpha’ genotype for early season planting and ‘Ashley’ genotype for late season are recommended for cultivation in the Derived Savannah, Southeast Nigeria agro ecological zone.

Genetic variability and correlation analysis were studied in 20 accessions of ‘egusi’ melon during two growing seasons. The genotypic correlation coefficients with seed yield were partitioned into direct and indirect effect causes. Heritability in the broad sense ranged from 17% for fruit circumference to 90% for days to germination and flowering in the early season, while in the late season, heritability ranged from 7% for seed weight per fruit to 88% for days to germination. High phenotypic and genotypic coefficients of variation were recorded for seed yield while days to maturity had the lowest in both seasons. Fruit circumference and fruit weight had significant genotypic and phenotypic correlation with seed yield in the early season, while number of branches per plant, vine length per plant, number of fruits per plant and fruit circumference per plant showed significant genotypic and phenotypic correlation with seed yield in the late season. Environmental correlation coefficients were significant between seed yield and vine length per plant, number of fruits per plant and fruit size per plant. Vine length per plant and fruit circumference per plant had the largest positive direct effect on seed yield. Knowledge of the relationship of these characters with seed yield will aid in the selection of genotypes that have high seed yield, which will also be specific to the two major seasons in the year.

An experiment on the standardization of time of planting for growing cucumber(Cucumis sativus L.) inside polyhouse was conducted during 2010-11 at the Horticutural Experimental Field, College of Agriculture, Central Agricultural University, Imphal (Manipur), India. The experiment comprised of four dates of planting (September, October, November and December) and two cucumber varieties viz.Alamgir CT 280 and Alamgir CT 380, in Factori-al Randomised Block Design with three replications and eight treatments.Impact of time of planting was established on vegetative characters; flowering and fruiting characters; yield and yielding attributes. Effect of different time of planting and variety on growth of cucumber was found to produce significant effect (at 5% level of probability) on main vine length, numbers of leaves per plant and leaf area. For both the varieties, September planting gave maxi-mum values of main vine length (221.93 cm and 240.51 cm, respectively), number of leaves per plant (21.21 and 21.92, respectively) and leaf area (393.26 cm2 and 413.76 cm2, respectively). The treatment combination of Septem-ber planting with Alamgir CT 280 gave shorter number of days (12.6) from fruit set to maturity. The different time of planting and varieties and their interactions showed significant effect on number of fruits per plant, fruit length (cm), fruit diameter (cm), single fruit weight (g), fruit yield/plant (kg) and fruit yield/ha (t). The results revealed that the treatment combination of September planting with Alamgir CT 380 gave the highest yield (47.31t/ha), as compared with October, November and December plantings. However, the maximum cost- benefit ratio (1: 2.24) was found in October planting. The present study suggests that cucumber can be grown successfully during winter months under polyhouse in Manipur, India condition.

Twelve exotic cultivars of cucumber (Cucumis sativus) were grown to assess the presence of variability for desired traits and amount of variation for different parameters. Genetic parameters, correlations, partial correlation and regressions were estimated for all the traits. Analysis of variance revealed significant differences among entries for all the characters. The estimates of genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were high for yield per plant, fruits per plant, fruit weight and fruit length. Broad sense heritability estimates for various traits ranged from 42.26 to 89.55%. Fruit yield per plant showed high significant positive correlation with fruits per plant, fruit weight, flesh thickness, fruit diameter and leaves per plant. Partial correlation was significant for fruits per plant and indicated these traits contributed over 70% to total fruit yield. By variability, correlation and regression analysis it was concluded that more fruits per plant and more fruit weight are major yield contributing factors in selecting high yielding cucumber cultivars.DOI: http://dx.doi.org/10.3329/bjpbg.v25i1.17008

The present investigation was carried out to estimate the genetic variability and character association. Significant differences were observed among the genotypes for all the 15 traits for 20 chili genotypes. The highest genotypic coefficient of variation and phenotypic coefficient of variation were found for ten edible fruit weight, number of fruits per plant, fruit yield per plant, ten dry fruit weight, fruit length, fruit width, and weight of seeds per fruit. High heritability coupled with very high genetic advance as per cent of mean was observed for ten edible fruit weight, ten dry fruit weight, fruit length, number of fruits per plant, and fruit yield per plant. Phenotypic correlation coefficient among different traits indicated that fruit yield per plant at green stage had significant and positive association with ten edible green fruit weight, number of primary branches, harvest duration, and first fruit maturity and significant negative correlation with days to first picking. The path coefficient analysis revealed that days to first picking had the maximum positive direct effect on fruit yield per plant followed by harvest duration, ten edible fruit weight, ten dry fruit weight, hundred-seed weight, number of fruits per plant, first fruit maturity, and number of primary branches. Days to first picking had the maximum positive direct effect but significant negative effect with fruit yield per plant which indicated that the trait should be selected to expunge the undesirable indirect effect in order to make use of the direct effect. Therefore, selection should be practiced for ten edible fruit weight, ten dry fruit weight, number of fruits per plant, harvest duration, and hundred-seed weight for direct improvement of fruit yield per plant.

The objectives of this work were to assess zucchini heterogeneity index and fruit weight at different harvest frequencies for plants grown on a protected environment; to estimate the optimum plot size; and to determine the least significant difference among treatments, varying plot size and replication number. Plants of cultivar Caserta were grown in a plastic greenhouse, using spaces of 0.80 x 1.00 among plants and lines, respectively. The following harvest frequencies were studied: fruits harvested daily, (1) at 10:00, (2) at 10:00 and 18:00, (3) at 8:00, 10:00, 12:00, 14:00, 16:00 and 18:00 h and; (4) fruits harvested every other day, at 18:00 h. Twenty-seven harvests were carried out, collecting fruits larger than 0.15 m. Plots were planned with 1, 2, 3, and 6 plants per row. Heterogeneity index was estimated according to Smith's method and, the optimum plot size, according to modified maximum curvature method. Fruit yield per plant gradually increased reaching a maximum at the 15th harvest. Total yield was of 3214, 3124, 3928 and 3248 g plant¹, respectively, at the harvest frequencies 1, 2, 3 and 4, with no significant differences among them. The heterogeneity index in the plastic greenhouse was nearly zero. The use of smaller plots combined with a larger number of replications increased the experimental accuracy. Although optimum plot size to assess total fruit yield varied between one and seven plants, depending on the harvest frequency, plots with three plants per row plots, with six replications, were the most appropriate design, allowing detecting a least significant difference among treatments equal to 76% of the mean.

Present study aimed to evaluate the production potential of cape gooseberry (Physalis peruviana L.) in sodic soil (pH 8.56) under varying plant spacing and soil fertility levels. The spacing treatments were S1-75 x 60 cm, S2-75 x 75 cm and S3-90 x 75 cm, while native soil fertility was manipulated through the application of NPK fertilizers i.e. F0-control (no NPK fertilizers), F1 - 60:40:40, F2 - 80:60:60, and F3 - 100:80:80 kg NPK ha-1. Two year’s data from the study revealed that spacing and NPK treatment had significant effect on vegetative growth and fruit yield during both the years. Closest spacing (75 x 60 cm) resulted tallest plants (103.41 and 100.35 cm) and maximum fruit yield (86.69 and 83.56 q ha-1), but this treatment was statistically at par with 75 x 75 cm spacing. Widest spacing (90 x 75cm) resulted maximum number of branches (34.14 and 32.49 plant-1), number of leaves (167.31 and 162.70 plant-1) and average fruit weight (9.26 and 9.18 g), but was statistically at par with 75 x 75 cm spacing. Amongst the fertilizer treatments, application of NPK @100:80:80 kg ha-1 resulted maximum plant height (114.88 and 11.65 cm), number of branches (35.78 and 34.82 plant-1), number of leaves (174.82 and 172.55 plant-1), fruit weight (9.62 and 9.57 g) and fruit yield (101.08 and 98.08 q ha-1). Biochemical quality of fruits (TSS, ascorbic acid, acidity, and reducing, non-reducing and total sugars) was increased due to increased fertility level and recorded maximum with the application of 100:80:80 kg NPK ha-1. These findings will be helpful in exploring cape gooseberry cultivation in sodic soils (pH 8.56) through suitable agronomic manipulations in plant spacing and soil fertility levels.

Calcium sprays (CaCl2, Mora-Leaf-Ca + Link Ca, or Stopit) increased fruit Ca concentrations and reduced the incidence of cork spot of `Anjou' pears (Pyrus communis L.) during four seasons. All Ca sprays increased yield relative to the control. All sprays resulted in some injury to leaves and fruit, but fruit was acceptable for marketing. At the low rate, Stopit sprays were the least injurious. Early season sprays, in June to July, produced less leaf and fruit injury than late-season sprays, in July to August, or early + late-season sprays. Early or late-season Ca sprays resulted in slightly larger fruit than early + late sprays. Either late or early + late-season sprays led to higher Ca concentrations in fruit cortex than early sprays.

The experiment of the present research work was conducted during summer season of 2018-19 and 2019-20 at Horticulture Research Farm-I, Department of Horticulture, School of Agricultural Sciences and Technology, Babasaheb Bhimrao Ambedkar University (A Central University), Vidya-Vihar, Rae Bareli Road, Lucknow (U.P.), India. The analysis of variance clearly reveals significant differences among the genotypes for all characters. The observations recorded on various characters showed that the estimates of phenotypic coefficient of variation (PCV) were higher than genotypic coefficient variation (GCV) for all characters. The high phenotypic as well as genotypic coefficient of variation were observed in marketable fruit yield per plant (39.36%) followed by average fruit weight (29.73%) and number of branches per plant (27.18%). High estimates of heritability were recorded for different characters viz., average fruit weight (98.6%) followed by total soluble solids (97.8%), total sugars (97.7%) and days to anthesis of first pistillate flowers (97.2%). The parameters which observed were found to be very high estimate value of genetic advance in per cent of mean of (60.14%) average fruit weight (60.14%) followed by titratable acidity (53.73%), number of branches per plant (53.47%), total soluble solids (52.81%) and marketable fruit yield per plant (47.87%).
