Salicylic acid and Benzoic acids are antitranpirants usually used to reduce the rate of moisture loss and increase productivity of irrigated crops. To test antitranspiracy of Salicylic and Benzoic acids, field experiments were conducted during the two successive dry Seasons of 2011/2012 and 2012/2013 at the Agricultural Research Station Farm, Kadawa (11̊ 38ʹ 40.3ʺ N,8̊ 25ʹ3.9ʺ E) 498m elevation above sea level. The aim was to study the effects of antitranspirants and moisture stress on crop growth and development stages of tomato. The treatments consisted of two antitranspirants at four different concentrations of 0, 200, 400 and 600 ppm, and three moisture stress stages, vegetative, flowering and fruit setting. Antitranspirants and moisture stresses were assigned to the main plot and concentrations were used as sub–plot treatment. These were replicated three times and laid out in a split-plot design. The gross plot size was 3.6m x 3.0m (10.8m2) consisting of 6 rows of 3m length, while the net plot size was 1.2m 1.8m (2.16 m2) consisting of 2 inner most rows. Data were taken on tomato growth and yield attributes. Data generated were analysed using statistical analytics software (SAS). The results of the study revealed that application of both Antitranspirants enhanced growth and yield components such as fruit diameter, number of fruits plant1, average fruit weight, marketable fruit yield and total fruit yield of tomato. Significant interactions between and among the factors were also recorded for fruit diameter, number of fruits plant-1 marketable fruit yield and the total fruit yield. Application of 200 and 400 ppm of of Salicylic acid at fruit setting produced the highest total fruit yield (6.66 tha-1) which was statistically similar to 600 ppm of Benzoic (6.10 t ha-1) at flowering while the control had the lowest. Total fruit yield was positively and significantly correlated with number of fruit plant-1 and average fruit weight. Number of fruits plant-1 was found to have the highest direct contribution to the yield. Flowering and fruiting stages were found to be the critical growth stages for moisture stress of tomato. Foliar application of 400 ppm of Salicylic acid at fruit setting stage appeared to promote tomato yield in the study area.

The study was carried out to find out the effect of zinc (Zn) and boron (B) on growth and yield of okra (BARI Dherosh 1). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The treatments of the experiment were, T0 (without Zn or B), T1 (20 kg Zn ha-1), T2 (30 kg Zn ha-1), T3 (10 kg B ha-1), T4 (20 kg B ha-1), T5 (20 kg Zn ha-1 + 10 kg B ha-1), T6 (20 kg Zn ha-1 + 20 kg B ha-1), T7 (30 kg Zn ha-1 + 10 kg B ha-1) and T8 (30 kg Zn ha-1 + 20 kg B ha-1) were undertaken to evaluate the best results of the study. The highest plant height was found in T8 (30 kg Zn ha-1 + 20 kg B ha-1) but the highest number of leaves plant-1 was recorded from T7 (30 kg Zn ha-1 + 10 kg B ha-1). On the other hand, the maximum leaf area index, SPAD value, mean fruit weight, fruit length, fruit diameter, fruit dry matter (%), number of fruits plant-1, fresh fruit weight plant-1 , fruit yield plot-1 and fruit yield ha-1 were found in T7 (30 kg Zn ha-1 + 10 kg B ha-1), while the control (T0) showed lowest performance for the respected parameters. It is strongly concluded that 30 kg Zn ha-1 with 10 kg B ha-1 combination may be helpful for okra cultivation in the field level to increase okra production.

An experiment was conducted to evaluate the performance of hybrid tomato lines on growth and yield performance at Regional Agriculture research Station (RARS), Parwanipur, Nepal during end of September, 2018 to April, 2019. The experiment was laid out in randomized complete block design (RCBD) with seven hybrid tomato lines as treatments and three replications. The tested lines included Srijana and Dalila as check varieties and other lines, developed by crossing HRA and HRD lines which showed better performance under late blight conditions. HRA 20× HRD 1 showed significantly higher plant height (110.67 cm) which was statistically at par with genotype HRA 14× HRD 7. The highest number of fruits per plant (69) was recorded from Srijana whereas the lowest number of fruits per plant (37) was recorded from cv. HRA20 × HRD1. The fruit yield of the lines ranged from 50.54 t/ha to 32.2 t/ha with Srijana having the highest yield and HRA 20× HRD 1 as the lowest. Similar results were shown regarding the marketable fruit yield. However, the highest individual fruit weight (34.67g) was recorded in HRA 14× HRD 7 and the least fruit weight was recorded in Srijana (24.22 g). Results showed that the maximum TSS (5.53 0Brix) was recorded from Dalila which was similar as Srijana. Hence, the overall performance of Srijana was recorded superior regarding both quantitative and qualitative suggesting Srijana as the recommended variety in the given domain. Here authors concluded that Srijana is still a comparatively better hybrid variety in Nepal.

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.

Graft Success

Grafting is regarded as an integral component of sustainable vegetable production. It is important in the management of soil-borne diseases, and reports suggest that grafting with viable rootstocks can enhance crop growth and yield. This research was conducted using splices and cleft grafting techniques to investigate graft compatibility among varieties of high yielding eggplant scion (MCV1, MCV2, CCV1, CCV2, CCV3, NCV, and TCV) grafted onto wild rootstocks (MWR, BWR, and TWR) to study their morphophysiological and yield characteristics. High yielding scions grafted onto wild relative rootstocks were compared with two controls including self-grafted and non-grafted. All the scion had a high rate of germination (≥95%) and remarkable graft success (100%) was recorded in MCV1, MCV2, and TCV using the cleft techniques. Generally, the use of rootstocks resulted in higher total and marketable fruit yield compared to the non-grafted and self-grafted scion plants, respectively. In particular, MWR and TWR rootstock conferred the highest vigour to the scion, resulting in the highest values recorded for total and marketable fruit yield, number of fruits per plant and average fruit weight. A similar result was obtained in fruit length and diameter, where long and wide fruits were observed in scions grafted onto MWR and TWR rootstocks, respectively. Grafting of high yielding eggplant scion onto resistant MWR, BWR and TWR eggplant rootstock was found to be beneficial for eggplant cultivation. The remarkable compatibility and vigour of the rootstock with scion led to the improvement in total and marketable yield of the fruits. As such, it can be concluded that the use of wild relative rootstocks of eggplant species can be a valuable method of improving eggplant production.

The experiment was conducted at Sher-e-Bangla Agricultural University's Horticulture Farm, Sher-e-Bangla Nagar, Dhaka-1207, to determine the effect of pruning and GA3 on squash growth and yield over the period from November 2017 to February 2018 Three levels of pruning as P0 = No pruning (control), P1 = 1st pruning at 20 DAT (1st and 2nd leaves) and P2 = 2nd pruning at 30 DAT (3rd and 4th leaves) and four levels of GA3foliar application as G0 = No GA3 (control), G1 = 100 ppm GA3, G2 = 200 ppm GA3 and G3 = 400 ppm GA3 considered for the present study. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Considering growth parameters, pruning treatment had a significant effect on growth, yield contributing parameters and yield of squash except for stem base diameter and individual fruit weight. Regarding GA3 treatments, growth and yield parameters were significantly influenced except fruit diameter. In terms of the combined effect of pruning and GA3 treatments, all the studied growth and yield parameters were significantly influenced. The highest stem length (64.73 cm), number of leaves plant-1 (23.59), stem base diameter (2.09 cm), number of male flower plant-1 (8.69), number of female flower plant-1 (7.52), total number of fruits plant-1 (5.74), fruit length (22.42 cm), fruit diameter (6.15 cm), individual fruit weight (507.66 g), dry weight of fruit (6.61%), weight of fruits plant-1 (2914.33 g) and fruit yield ha-1 (29.14 t) were also found from the treatment combination of P1G1 compared to the other treatment combination. Hence, we can summarize that 1st pruning at 20 DAT (1st and 2nd leaves) with 100 ppm GA3 given the maximum output in terms of yield compared to other treatments.

Okra is India’s most widely grown tropical and subtropical vegetable crop. Despite widespread cultivation, crop yield and productivity remain subpar. Yellow vein mosaic virus (YVMV) disease is a serious threat to Indian okra production, causing yield losses ranging from 17.09 to 96.49 per cent. In this context, the present study was aimed to assess the variability and character association of 74 elite germplasm accessions for thirteen quantitative and quality traits. High phenotypic and genotypic coefficient of variation (PCV and GCV) were observed among all evaluated traits except fruit diameter, which showed a moderate PCV and GCV. All traits had high heritability and high genetic advance, implying that the heritability was most likely due to additive gene effects. Direct selection of these traits would be advantageous for okra improvement, especially in developing a YVMV resistant genotype. Fruit yield per plant exhibited a significant and positive genotypic as well as phenotypic correlation with fruit weight, fruit length, peroxidase activity, polyphenol activity, fruit diameter, total phenolic content and plant height, whereas node at which the first flower appeared and YVMV were negatively correlated to fruit yield per plant. Correlation studies indicated YVMV resistance towards high total phenolic content, polyphenol oxidase, and peroxidase. The high positive direct effects on fruit yield per plant were observed for fruit weight followed by number of fruit per plant and total phenolic content. This study revealed that simultaneous selection of these traits can help in increasing yield and YVMV resistance.

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

Studies were conducted in 2006 at Clinton and Kinston, NC, to determine the influence of halosulfuron POST (over the crop plant) or POST-directed (to the crop) on growth and yield of transplanted ‘Precious Petite’ and ‘Tri-X-313’ triploid watermelon. Treatments included a nontreated control, 39 g/ha halosulfuron applied POST-directed to 25% of the plant (distal or proximal region), POST-directed to 50% of the plant (distal or proximal; Precious Petite only), and POST. Watermelon treated with halosulfuron displayed chlorotic leaves, shortened internodes, and increased stem splitting. Vines were longest in the nontreated control (Tri-X-313 = 146 cm, Precious Petite = 206 cm) but were shortest in the POST treatment (Tri-X-313 = 88 cm, Precious Petite = 77 cm). Halosulfuron POST to watermelon caused the greatest injury (Tri-X-313 = 64%, Precious Petite = 67%). Halosulfuron directed to 25 or 50% (distal or proximal) of the plant caused less injury than halosulfuron applied POST. Stem splitting was greatest when halosulfuron was applied to the proximal area of the stem compared with POST-directed distal or POST. Internode shortening was greatest in treatments where halosulfuron was applied to the distal region of the stem. However, Tri-X-313 in the POST-directed 25% distal treatment produced similar total and marketable fruit weight as the nontreated control at Clinton. Fruit number did not differ among treatments for either cultivar. At Kinston, Precious Petite nontreated control and POST-directed 25% distal end treatment had greater marketable fruit weight than the POST-directed 50% proximal and POST treatments. The current halosulfuron registration allows POST application between rows or PRE. Limiting halosulfuron contact to no more than 25% of the watermelon plant will likely improve crop tolerance.

At Yarwun (151.3˚E, 23.75˚S), Australia, papaya Hybrid 29 yielded twice as much fruit as Hybrid 11 and 30% more than Hybrid 13. The plots mulched with coarse grass hay yielded 50% more fruit than the plots with bare ground. The highest yielding treatment, Hybrid 29 + mulch, averaged the equivalent of 81 t/ha.year over the 16.5-month harvest period. The yields were achieved in spite of inadequate water supply due to drought and the loss of 877 plants from 1441 plant positions (4 plants per position) due to the 3 phytoplasma diseases; dieback, yellow crinkle and mosaic. Hybrid 29 produced higher yields than the other hybrids by flowering early on shorter plants with thicker stems and setting more fruit that commenced lower down on the stem. Hybrid 13 was intermediate in size and the amount of fruit setting between Hybrid 29 and Hybrid 11 but was the slowest to flower and set fruit. Hybrid 11 had the thinnest and tallest stems, flowered at an intermediate time between the other 2 hybrids and produced fewer flowers and fruit resulting in the lowest yield. Mulching increased stem height and thickness, promoted earlier flowering and increased fruit set, yield and average fruit weight
