Tomato Genotypes

This study was conducted to estimate heterosis for the yield and yield contributing traits of 32 cross combinations involving 12 diverse lines of some Bangladeshi tomato genotypes considering line x tester mating fashion at the experimental field of Sher-e-Bangla Agricultural University, Dhaka in 2016-2017 and 2017-2018 winter season. The experiment was designed in a Randomized Complete Block Design (RCBD) with three replications. The analysis of variance (ANOVA) showed highly significant difference for all the characters suggesting the presence of genetic variability among the studied materials. Four cross combinations (L1xT1, L3xT2, L3xT3, L5xT1) showed desirable negative significant heterosis for days to first flowering in both relative heterosis (RH) and heterobeltiosis (HB) ranged from -2.56% to -19.05%, respectively. Highest positive significant heterosis in both RH and HB was observed in four crosses L4xT4 (63.48% and 48.25%), L5xT2 (46.77% and 46.27%), L5xT4 (62.58% and 34.78%) and L8xT3 (37.39% and 35.12%) for individual fruit weight (g), while six crosses L1xT2, L1xT4, L3xT2, L4xT4, L5xT4 and L6xT1 exhibited highest positive significant heterosis for yield per plant (kg) in both HB and RH ranged from 16.09% to 88.46% respectively. Heterotic hybrids with maximum number of studied desirable yield contributing traits (8) of both RH and HB were identified only two crosses L1xT2 and L4xT4.

Pruning Methods

This study was carried out to determine the effect of vine and fruit pruning on watermelon (Citrullus lanatus) yield. Five pruning methods: P1=no pruning at all, P2=pruning to four vines with two fruits per vine, P3=pruning to four vines with one fruit per vine, P4=pruning to three vines with two fruits per vine and P5=pruning to three vines with one fruit per vine were evaluated on two watermelon cultivars: ‘Sugar baby’ and ‘Julie F1’ under a factorial randomized complete block design with three replications. Investigations were carried out in the seasons 2017A (short rains) and 2017B (long rains) at Karama and Rubona experimental sites belonging to Rwanda Agriculture and Animal Resources Development Board. The obtained results indicated a significant difference among the different cultivars and pruning methods tested during both seasons and at two sites. Generally, all studied parameters recorded higher values during season 2017B than in season 2017A at Rubona site. A similar trend was recorded at Karama site except that the fruit yield per plant and per hectare for plants which were pruned to three vines with one fruit reduced during season 2017B as compared to season 2017A. The highest number of fruits per plant, fruit weight, fruit yield per plant and per hectare was recorded in ‘Julie F1’ compared to ‘Sugar baby’ at both sites and during both seasons. Higher fruit weight was obtained when both cultivars were pruned to three or four vines with one fruit per vine. Higher number of fruits per plant and higher fruit yield per plant was observed under pruning to four vines with two fruits per vine at Rubona site; while at Karama site, higher fruit yield per plant was recorded under pruning to three vines with one fruit or two fruits per vines and pruning to four vines with two fruits per vine. A similar trend was observed in fruit yield per hectare. Based on results of the current study, cultivation of the hybrid ‘Julie F1’ and pruning to three vines with one fruit per vine is recommended for optimum watermelon yield with big-sized fruits.

In this study, we investigated the fruit, seed yield and biofuel production potentials of Jatropha curcas in soils fertilized with different rates of rice husk dust (RHD) and NPK 10:10:10. This study took place at the Teaching and Research Farm of the Department of Horticulture and Landscape Technology, Akanu Ibiam Federal Polytechnic, Unwana from April 2020 to March 2021. Treatments comprised of six rates (0, 1,2,3,4 and 5 ton ha-1) each of RHD and NPK, arranged in Randomized Complete Block Design (RCBD in Randomized Complete Block Design (RCBD) in a factorial pattern. Nursery Jatropha seedling of average heights of about 30 cm and 5-6 true leaves were transplanted to the field a month after treatment application. Our measurement between 10 to 12 months of Jatropha growth focused on the number of fruits, weight of fruits, number of seeds, weight of seeds and quantity of oil per plant. Analysis of variance (ANOVA) and Least Significant Difference (LSD) tools were used to analyze the obtained data and separated the significant means respectively. The relationship between yield parameters and selected soil chemical properties was determined using correlation analysis. Results indicated that relative to control, addition of RHD and NPK as lone and combined treatments increased the fruit, seed yield and oil quantity of Jatropha. Relative to control, fruit number increased by 72.80%, fruit weight by 79.81% and number of seeds by 80.73%. Similarly, the seed weight and oil content increased by 28.11% and 21.485 respectively. Organic matter, available phosphorus and total nitrogen had highly significant correlation with fruit, seed yield and oil quantity. Treatments combination of 5tonha-1 RHD and 5tonha-1 relatively gave the most appreciable result in fruit, seed yield and oil quantity and therefore recommended.

This study was conducted with an area of 540 square meters excluding canals and was divided into twenty plots. Each plot was measured 3m x 9m. The experimental area was laid out following Randomized Complete Block Design (RCBD). The study aimed to determine the effect of different row spacings and schedule of urea application in medium level on the yield of sweet corn. Results of the analysis showed that the average length and average circumference of corn ears in centimeter per plot per treatment both showed no significant difference as affected by different row spacings and schedule of application of urea. Results of the Analysis of Variance (ANOVA) on the average weight and total weight of corn ears in kg per plot per treatment showed that there was significant difference on the yield of sweet corn using row spacings. However, no significant difference on the schedule of application of urea. Thus, R2 is recommended in terms of longest husk, biggest circumference of husk, and heavier husk of corn ears. On the other hand, R1 is recommended to obtain more husk of corn ears and R5 is recommended to obtain heavier husk of corn ears.

Shallot is an important spice and seasoning in Indonesia. It is consumed almost daily in many dishes. The objective of this experiment was to study the effect of the medium and the variety on the yield of shallots grown in a polybag. The experiments were arranged in a two-factorial randomized complete block design with three replications. The factors were medium (1 soil: 1 paddy husk ash and 1 soil: 1 compost) and variety (Agrihorti 1 and Mentes). Data were statistically analyzed by Analysis of Variance (ANOVA), and the means were compared using Honestly Significant Difference (HSD) at P < 0.05. There was no interaction between medium and variety. Overall, all treatments did not significantly affect yield. Varieties were significant differences on bulb diameter; however, they were not significant differences on bulb height, fresh bulb weight per polybag, and bulb number per polybag. Those media are considered as precise media due to they contain organic materials.
