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.

Prime Source

Vegetables are the prime source of vitamins and minerals. As the population increases there is also increase in demand for nutritional vegetables, but in the conventional method of horticulture the production and productivity is considerably less. Thus to increase the productivity and to feed the over burgeoning population there is a need for novel fertilizers such as Nano fertilizers. An experiment was hence conducted in Chinapettai village, Panruti to investigate the Bio-efficacy of Nano nutrients (Nano Nitrogen, Zinc and Copper) on growth and yield of Capsicum. The experiment was carried out in RBD design (Randomized block design) with three replications and ten treatments. Results showed that the treatment with 100% RD-N+100% RD-P + 100 % RD-K + Nano N + Nano Cu + Nano Zn followed by 100% RD-N +100% RD-P + 100 % RD-K + Nano N and 75% RD-N+100% RD-P + 100 % RD-K + Nano N + Nano Cu + Nano Zn recorded maximum growth and yield parameters. In contrast 50% RD-N + 100% RDP + 100 % RD-K + Nano N showed increase in yield than the control (100% RDF (-N: -P: -K)(250:150:150kg/ha)) to conclude that Nano nitrogen could have compensated the 50% urea recommendation in conventional fertilizer and also had enhanced effect than control.

Protected vegetable cultivation is a fast-growing sector in which grafting plays a crucial role for success. Cucumber is predominantly grown under protected conditions. The popular slicing (mini) cucumber comprises two segments, single- and cluster-fruit-bearing. In the present study, the performance of select fruit-bearing hybrids grafted as scions onto commercial Cucurbita hybrid rootstock ‘NS-55’ was evaluated under three different low-cost protected structures in arid regions. With respect to type of protected structure, cucumber performance was superior under a naturally ventilated polyhouse (NVP) than an insect net house (INH) or a shade net house (SNH). Micro-climate parameters inside NVP (air temperature, RH and PAR) were more congenial for cucumber than those in net houses, thereby facilitating improved physiology (chlorophyll fluorescence, chlorophyll and plant water potential) and leaf mineral status. Grafting invariably improved growth and yield parameters under all protected structures. Overall plant performance was better in the grafted cluster-fruit-bearing hybrid ‘Terminator’ than the single-fruit-bearing hybrid ‘Nefer’ or their non-grafted counterparts. Furthermore, NVP was found to be superior to net houses for water productivity, and grafted plants were more water use efficient than their counterpart non-grafted plants. Thus, NVP can be considered a suitable low-cost protected structure in conjunction with grafting to boost cucumber crop and water productivity in arid regions.

Tomato is a major food that has many benefits to human health. The risk of getting disorders such as heart disease, cancer, and diabetes can be reduced by consuming tomato. The aim of this study is to measure the nutritional properties of tomato plants using various cultivation methods. On the other hand, this is also comparing which type of fertilizer, either chemical fertilizer or natural fertilizer, is producing better results in planting tomato. Phosphorus solubilizing bacteria (PSB) is isolated from the rhizosphere soil using the Pikovskaya medium and Modified Aleksandrow medium. Instead of chemical fertilizer, the efficiency of phosphate solubilize will be evaluated in the presence of eggshells and bones. This study starts with the collection of rhizosphere and non-rhizosphere soil for tomato planting. The land of cultivation for planting well estimated for the growth of tomato. For further investigation, the leaves and fruits obtained from the tomato plants will be dried and ground into powder form. The leaf is used for the estimation of chlorophyll. In contrast, the fruit powder is used for the analysis of antioxidant activity. The result showed that the growth and yield parameters of the plant increases with natural fertilizer compare to chemical fertilizer. This can be concluded that natural fertilizers are more preferable in the agriculture industry as they are environmentally friendly, which does not produce side effects in either the soils or the crops.

Arab Journal of Plant Protection, 39(1): 79-83. Tomato is an important vegetable crop, belongs to the family Solanaceae and is the second most consumed vegetable following potatoes. The tomato crop is grown all over the world in both summer and winter seasons, and plant viruses are a major threat to tomato production. Among these viruses, tomato leaf curl virus (TLCV) causes considerable yield loss to tomato crop. This virus is transmitted by a whitefly (Bemisia tabaci) vector. In this study, the effect of TLCV infection, on the following tomato growth and yield parameters, was evaluated: plant leaf number and area, plant biomass, plant height, root length, and plant stem diameter and yield. Tomato plants were transplanted in wellprepared plots with 4 replications. The control group was covered with polyethene bag to avoid whitefly infestation. Plants were scored on the 15th and 30th day after inoculation and TLCV disease severity was recorded. Analysis of variance (ANOVA) showed the significant differences between the healthy and infected tomato plants. Moreover, growth and yield parameters were reduced with the increase in disease incidence, disease severity and whitefly infestation. Disease severity was increased with the increase in temperature during the growing season. It can be concluded from this study that TLCV significantly affects growth and yield of the tomato crop. Keywords: Tomato, Tomato leaf curl virus, TLCV, disease incidence, disease severity.

Background: French bean (Phaseolus vulgaris L.) is an important and widely grown leguminous vegetable. The area under this crop in protected cultivation is increasing due to its high yield and remunerative price. There is scanty of information on pacing and nutrients for fertigation under protected cultivation. Hence the experiment was carried out to determine the effect of spacing and fertigation on growth and yield parameters in French bean under naturally ventilated polyhouse during Kharif 2018 at Zonal Agricultural and Horticultural Research Station, Navile, Shivamogga.Methods: The experiment was laid out in split plot design with three replications. There were 18 treatment combinations comprised of three different spacing treatments and six fertigation treatments. Result: Among all the treatments significantly highest number of primary branches (8.70) and secondary branches (8.50) at 45 days after sowing (DAS), number of pods plant-1 (220.20), pod length (20.66 cm), pod girth (2.95 cm) and pod weight (17.69g) were recorded in the treatment combination with 60 × 75cm with 44:70:53 kg ha-1 + mulching + micronutrient spray. The least number of primary branches (4.27), secondary branches (4.50), number of pods plant-1 (160.33), pod length (15.61cm), pod girth (1.75 cm) and pod weight (13.88g) were observed in the treatment combination with 60 × 45 cm spacing with 33:52.5:39.75 kg of N:P:K kg ha-1. The higher plant height at 45 DAS (480.50 cm) and yield (13.06 t) for 1000 m-2 was found in treatment combination 60 × 45cm with 44:70:53 kg ha-1 + mulching + micronutrient spray (S3T4). It was concluded from the study that, the closer spacing (60 × 45cm) with the combination of 44:70:53 kg ha-1 (N:P:K), mulching and micronutrient spray resulted in higher pod yield (13.06 t) 1000m-2.
