Vegetable, due to higher neutraceutical component, are termed as protective food against various major and minor diseases. Scientific agro-techniques under optimum growing condition like temperature, relative humidity and light intensity, positively influence the qualitative and quantitative attributes of most of the vegetable crops including cherry tomato. It is one of potential vegetable crop, which is extensively utilized for table purpose and for preparing recipies in five star restaurants. Cherry tomato fetches higher prices in market due to good taste and higher nutrients, thus making qualitative attributes as an important factor to give higher returns to the farmers. Thus, this experiment was conducted to estimate the qualitative attributes in eighteen genotypes of cherry tomato grown under both open field and polyhouse conditions. The result of the study revealed that under open field condition, BRCT-30 was the best genotype with maximum value for lycopene content (6.62 mg 100-1 g FW) and β-carotene (2.30 mg 100-1 g FW), second maximum value for total soluble solids (7.85°Brix), third maximum value for reducing sugar and fourth highest position for ascorbic acid content (43.65 mg/100 g FW). Under polyhouse condition, the best genotype for quality parameters was BRCT-36 with maximum total soluble solids (10.81°Brix), lycopene (7.48 mg 100-1 g FW) and β-carotene (2.49 mg 100-1g FW) along with average range of values for ascorbic acid (72.36 mg 100-1 g FW) and titrable acidity (0.55 mg 100-1 g FW).

Arthropod Pests

Disease and arthropod pests are a continual problem for greenhouse vegetable production. These problems range from minor infestations to major disease or arthropod pest outbreaks that can destroy an entire crop. In Ontario, in the past, the major management strategy was pesticide control. However, many plant pathogen, insect and mite pests are resistant to registered pesticides and few new pesticides are being developed. Alternative control strategies exist or are being developed for most major pests. This review describes the current status of pesticide, cultural and biological control of disease and arthropod pests of greenhouse vegetables in Ontario and discusses the future possibilities for the integration of pest management practices utilizing plant resistance, nutrition, environment and biological control agents into an expert system approach. Key words: Vegetable (greenhouse) crops, integrated pest management

Pepper (Capsicum annuum) is one of the major vegetable species in the world, and Serbia as well. The pepper assortment of the Institute of Field and Vegetable Crops includes varieties of different fruit type such as the bell, conical, kapia, elongated, pepperoni and tomato-shaped peppers. However, in the assortment of the Institute, there is no variety of sweet pepper with conical and hanging fruits. Because of that, we wanted to develop a new pepper variety with this fruit type and offer it to the market. Selected lines from one of the crossbreeding combinations were grown in the open field and the greenhouse area by the pedigree method in the period 2012-2017. Based on the phenotype, the most vital plants that had the desired characteristics of the fruit were selected. During the many years of breeding, a new pepper variety NS Prva was obtained. NS Prva has been registered in the Republic of Serbia in 2019 and from that period it has been on the National variety list. The fruits of this variety are about 150 g, have one peak, grow hanging on the plant, with light yellow colour in technological maturity, and red in full maturity. A new pepper variety NS Prva is recommended for growing in a greenhouse where it gives uniform fruits suitable for the market in all maturity stages. It can also be recommended for growing in the open field where it gives slightly longer fruits. NS Prva showed good storage ability three weeks after harvest since it had the smallest reduction in fruit weight during storage in a cold chamber

Fusarium wilt of watermelon, caused by Fusarium oxysporum f. sp. niveum, is a destructive disease that limits watermelon production in many areas of the world. The discovery of several pyrenomycetous ascomycetes occurring naturally in association with different formae speciales of F. oxysporum identified these fungi as potential biological control organisms for watermelon wilt. One such mycoparasitic isolate, identified as Sphaerodes retispora var. retispora, was chosen for biological control and ecological trials in the greenhouse. Four different methods to inoculate the mycoparasite were evaluated, three of which utilized the parasite encapsulated into sodium alginate pellets. The other method employed root-dipping plants with mycoparasite ascospore suspensions. Ecological factors also were investigated, including the ability of S. retispora var. retispora to colonize watermelon roots, and its ability to survive in soil over time and reduce propagules of F. oxysporum f. sp. niveum. In the biological control studies, the use of the mycoparasite significantly reduced plant mortality and increased dry weights of watermelon plants after being challenged with F. oxysporum f. sp. niveum, compared with pathogen-inoculated controls. It appears that the incorporation of the parasite into alginate pellets in the planting mix at seeding may be the most practical method for future field evaluations of transplant-grown vegetable crops. In the ecological studies, the mycoparasite was recovered from infested soil after 9 months, but was only isolated from watermelon roots when applied in the presence of F. oxysporum. S. retispora var. retispora had no effect on F. oxysporum f. sp. niveum propagules after being applied to soils in the greenhouse.
