An investigation was carried out at the Department of Horticulture, University of Agricultural Sciences, Bangalore during summer-2017 to study the effect ofvaried levels of nitrogen and phosphorus fertigation on cherry tomato under open field and polyhouse conditions. There were 12 treatment combinations comprising of two growing conditions (open field and polyhouse), three levels of nitrogen (120, 150 and 180 kg N ha-1) and two levels of phosphorus (100 and 120 kg P2O5 ha-1) supplied trough fertigation with recommended potassium (150 kg h-1) as constant which were laid out in Factorial Randomized Complete Block Design with three replications. Result revealed that plant height (384.39 cm), fresh weight per plant (3.00 kg),nitrogen balance index (48.56), total leaf area per plant (6293 cm2), mean fruit weight (15.84 g), TSS content (6.30 ºB) and shelf life (15.66 days) were significantly higher under polyhouse condition with fertigation level of 180:120 kg N:P2O5 ha-1. However, significantly higher yield per hectare (78.16 t), Shelf life (15.66 days) and higher cost benefit ratio (4.81) were observed under open field condition with fertigation level of 150:120 kg N: P2O5 ha-1. Further, it can be concluded from the study that application of 150:120 kg N: P2O5 ha-1 through fertigation under open field condition is profitable during summer season in the Eastern Dry Zone of Karnataka.

Nine traits of 11 cherry tomato (Solanum lycopersicum L.) var. cerasiforme (Dunal) A. Gray) inbred lines exhibited a wide range of genetic variability. High geno- and phenotypic coefficients of variation were obtained for individual fruit weight (68.16 and 74.23%, respectively) followed by number of fruits/plant (58.8 and 68.34%, respectively). High estimates of heritability, genetic advance and genotypic coefficient of variation for the traits of individual fruit weight, number of fruits and clusters/plant were controlled by additive gene action indicating the possibility of selection to improve these characters. Fruit yield/plant showed low heritability along with low genetic advance and did not show significant and positive correlation with the remaining characters. It indicates that improvement of high yield through selection is difficult, rather hybridization can be effective for improving the fruit yield/plant. Among the lines, CH154 produced the highest number of fruits/plant (291) and highest fruit yield (1.89 kg/plant and 63.4 t/ha) and can be selected for cultivation under Bangladesh condition.

The present study entitled “Bioefficacy study of Bacillus subtilis based biofungicide on leaf spot disease, growth and yield attributes of tomato [Solanum lycopersicum L.] cv. ArkaVikas” was conducted at Vegetable Research Farm, Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during rainy season of 2016-17 in Randomized Block Design (RBD) with three replications. The treatments included foliar spray of chemical fungicide (Copper oxychlooride) and biofungicide (Taegro® and Trichoderma) either alone or in combination. Taegro® is a bacterial biofungicide containing 1×1010 CFU/g (13%w/w) of Bacillus amyloliuefaciens strain FZB24 formulated as WP. A total of 12 characters including disease, growth and yield parameters were studied. Disease parameter included leaf spot disease incidence (%) and disease severity (%) whereas growth and yield parameters included days to 50% flowering, height, number of branches per plant, fruit length (cm), fruit width (cm), number of fruits per plant, average fruit weight (g), number of seed per fruit, fruit yield per plot (kg), fruit yield per hectare (kg) were studied. The biofungicide Taegro exhibited significant potential in reducing the leaf spot in tomato and improving the growth and yield attributes of tomato as compared to control. But combined used of Taegro with standard chemical copper oxychloride gave better result than Taegro alone. As a consequence, this may be used as part of an integrated disease management approach so as to minimizes the use of standard fungicides and also protect the environment from pollution and maintenance of the human health.

Management Techniques

An experiment was conducted to identify suitable production management techniques for tomato (Solanum lycopersicum L.) cultivation during late winter-pre monsoon season in plains of Nepal. For this, organic mulches (rice straw, dried grass, and rice husk) were compared with SN (shade net) and no-mulch (bare field) condition for tomato yield in 2018 and 2019. The pooled analysis of all observed morphological and yield traits were performed and they differed significantly. Rice husk significantly affected number of fruits per inflorescence though number of inflorescence per plant and flowers per inflorescence were similar among organic mulches. The highest fruit yield per plant (4.44 kg plant-1) was obtained with rice husk, the other mulches and SN were at par but the lowest yield (2.75 kg plant-1) was obtained with no-mulch. Similarly, rice husk mulch contributed to the highest number of fruits per inflorescence (5.22), highest fruit weight (46.58 g) and diameter (4.99 cm).Fruit yield positively and significantly associated with fruit per inflorescence(0.78***), fruit diameter (0.65***) and an average fruit weight (0.56***).Organic mulches significantly (p=0.05) contributed to higher yield (86.01 t ha-1) over SN (76.55 t ha-1).Higher values for total soluble solid, Vitamin C and fruit firmness were observed under rice husk mulching. The result of the present study found rice husk mulching as better option for tomato production as compared to SN and no-mulch condition.
