The experiment was carried out at B.B.A. University, Lucknow (UP), India during rabi season of 2017-18 and 2018-19 to study the performance of tomato genotypes for growth and yield. The twenty genotypes were evaluated in randomized block design with three replications. Among the genotypes Pusa Sadabahar proved superior for growth and yield contributing characters i.e. plant height (30.9), number of branches per plant (7.0), number of cluster per plant (20.4), number of flower per cluster (9.8), number of fruits per cluster (5.0), number of fruits per plant (18.3), average fruit weight (53.0 g), fruit yield per plant (974.8 g), fruit yield (15.1 kg/plot) and fruit yield (36.1 tha-1) respectively, followed by Selection -7. On the other hand, minimum values of these parameters were recorded in Toleu-32, took plant height (25.1), number of branches per plant (4.5), number of cluster per plant (5.4), number of flower per cluster (5.6), number of fruits per cluster (3.1), number of fruits per plant (13.1), average fruit weight (41.9 g), fruit yield per plant (550.8 g), fruit yield (8.8 kg/plot) and fruit yield (20.4 t ha-1) consequently. The genotype Toleu-32 was significantly superior for days to 50 % flowering (41.9). The accession H-86 was found to be superior for TSS (5.4 0Brix). The check variety VRT-50 was found to be superior for vitamin C (27.7mg) followed by TLCV-16. [ABSTRACT FROM AUTHOR]

Shading is one of the cooling methods for changing the microclimate and maximizing crop growth in hot and sunny regions. A study was conducted to determine the effect of the growing environment on the growth, yield and fruit quality parameters of strawberries. The experimental treatments included net house, poly shed house, UV poly shed house, and open field (control) conditions. The results revealed that the plants grown in the net house condition had maximum plant height (18.5 cm), total chlorophyll content (62.66), fruit number (17), and yield (289.16 g/plant) of strawberries. In contrast, plants grown under UV poly shed conditions recorded higher total soluble solid (7 °Brix), titratable acidity (0.46 %), ascorbic acid (39.68 mg/100g) and lower pH (3.41). Reducing sugar (7.57 mg/g) and phenol (2.44 mg/g) levels were higher in fruits grown in poly shed. Results indicated that the most suitable growing condition for yield and yield parameters of strawberries is under the net house. In contrast, UV poly and poly house conditions are favourable for producing better quality fruit. [ABSTRACT FROM AUTHOR]

An experiment was conducted during the winter season of each of 2015/2016 and 2016/ 2017 at the Experimental field, Faculty of Agriculture, Zagazig University, Egypt in order to evaluate the response of caraway growth and yield under three rates of N:P:K:Mg at 13:5:26:3 ratios/ (0.0, 2.0 and 4.0 g/l) as foliar spray and three types of antioxidants (Control, salicylic acid, vitamin C and vitamin B1 as well as their combinations). The experiment was applied by a split-plot in randomized complete block design (RCBD) arrangement with three replications. Results proved the superiority of chemical fertilization as foliar spray via enhancing yield components of caraway plants in comparing with no application. Salicylic acid (SA), vitamin B1 (Vitam.B) and vitamin C (Vitam.C) at 100 ppm of each applied three times/season showed the best results in most of the studied growth parameters (plant height, number of leaves and branches per plant, total dry weight, root dry weight and root length) and yield components (number of umbels per plant and fruit yield per plant and per faddan) as compared with control. Accordingly, this study recommends the possibility of using antioxidants treatment (SA+ Vitam.B + Vitam.C) as an improving growth performance and yield components of caraway plants under chemical fertilization rate at 2 g/l.
