The study was conducted during 2020 in Chikkaballapur district which comes under eastern dry zone (Zone-V) of Karnataka. In Chikkaballapur district, two taluks i.e. Sidlaghatta and Chikkaballapur taluks were purposefully selected for the stud, since this taluk are having more area under protected cultivation technology. The ex-post-facto research design was used for the study In the present investigation, ex-post facto research design was used. This design was considered appropriate, as it is a systematic empirical enquiry for measuring the phenomenon, which has already occurred and is continuing. The total sample size comprises 100 of which, 50 growers (25 Chrysanthemum and 25 Capsicum) were selected randomly from Chikkaballapur taluk. Similarly, 50 growers (25 Chrysanthemum and 25 Capsicum) were selected randomly from Sidlaghatta taluk. The results of the study show that more than half of the horticulture crop growers were comes under middle age category, nearly one-third of growers were educated up to high school, more than two-fifth of the growers were small farmers, nearly one-fourth of the growers belonged to medium experience category, more than two-fifth of growers belonged to medium mass media exposure category. More than two-fifth of Horticulture crop growers had high scientific orientation. Two-fifth of the growers had medium achievement motivation. two-fifth of the horticulture crop growers had medium extension participation, more than two-fifth of the growers had medium level management orientation, majority of the growers were accessibility to credit and subsidy and nearly half of the growers belonged to medium risk bearing ability.

Evaluation of fifteen diverse genotypes of cucumber was carried out in a randomized complete block design for studying genetic divergence. Presence of wide genetic diversity, among the genotypes studied was confirmed by using Mahalanobis D2 statistics. Based on the interactions genetic distances of cucumber genotypes had grouped into five separate clusters inferring that the genetic divergence between them was quite high. The germplasm were so divergent, that only six genotypes were grouped in cluster V and three genotypes in each cluster I and III. The two genotypes SKY/AC-270-613481 and JB/11-091-613462 were grouped as cluster II and the genotype Tripura local was so divergent in all the characters that they were allotted as a separate group as cluster IV. Cluster mean analysis proclaimed that, genotypes in cluster I recorded maximum value for vine length (3.36 m), number of leaves per plant (43.85), number of branches per plant (12.98), leaf area (144.71 cm2), number of female flowers per plant (20.30), fruiting period (52.20 days), fruit set (89.10 %), average fruit weight (214.72 g), number of fruits per plant (19.00), fruit yield per plant (2.50 kg), fruit yield per ha (31.23 t/ha), rind thickness (2.79 mm) and flesh thickness (3.02 cm), whereas, same cluster I recorded minimum value for traits viz., internodal length (6.55 cm), days to appearance of first male flower (30.34 days), days to appearance of first female flower (31.81 days), node number at which first female flower appeared (4.00), days to first harvest (41.22 days) and number of seeds per fruit (211.69) which are negatively desirable characters in the crop production and crop improvement programme.
