ASSESSMENT OF PARTHENOCARPIC CULTIVARS OF CUCUMBER FOR HORTICULTURAL TRAITS UNDER NVPH
CHAUDHARI, VARSHABEN I.
The present investigation entitled “Assessment of parthenocarpic cultivars of cucumber for horticultural traits under NVPH” was carried out at Regional Horticultural Research Station (RHRS), Aspee College of Horticulture and Forestry (ACHF), Navsari Agricultural University, Navsari, Gujarat during kharif, 2014 and 2015. The experiment comprising sixteen different parthenocarpic cultivars, was laid out in a Randomized Block Design (RBD) with three replications. Most of cultivars behaved truly for this phenomenon over the year but 'JSCU 01' showed presence of staminate flowers in early growth stage of plants. The studies revealed significant variations among various cultivars for most of the vegetative, reproductive, yield and quality parameters except moisture content. Amongst the cultivars, 'CBA910569500' was significantly superior to other cultivars in respect to vine length at 30 (1.72 m, 1.51 m and 1.61 m) and 60 DAS (2.66 m, 2.14 m and 2.40 m) whereas, 'KUK 9' recorded significantly higher vine length at final harvest (4.56 m, 4.74 m and 4.65 m) compared to other cultivars in all the individual years as well as in pooled analysis. 'RS 03602833' expressed earliness in flowering as well as in picking, higher internodal length and number of nodes per vine in 2014, 2015 and in pooled analysis. 'KUK 6' exhibited superiority over remaining cultivars for node of first pistillate flower (4.60, 3.60 and 4.10) in all the individual years as well as in pooled analysis. Morphological characterization of fruits based on test guidelines did not reflect II much variation among cultivars. Thus cultivars could be grouped into 1, 2 and 3 groups for fruit traits like fruit shape, fruit shape at peduncle end and colour, fruit shape at blossom end, respectively. Fruit set of 86.92, 83.67 and 85.29 per cent was observed in cultivar 'Multistar' during 2014, 2015 and in pooled analysis, respectively. Amongst the cultivars, 'JSCU 01' surpassed all other cultivars significantly for leaf area index at 60 DAS, fruit length, fruit weight, fruit firmness and overall acceptability in all the individual years as well as in pooled analysis. 'Kian' ranked first in displaying higher fruit diameter and minimum Physiological loss in weight in pooled analysis. Whereas highest shelf life of 8.5 days corresponded to cvs. 'KUK 6', 'Multistar' and 'Ronino'. 'Multistar' produced higher number of fruits per vine (34.77, 33.47 and 34.11), which could be attributed to significantly higher leaf area index at 30 DAS displayed by this cultivar in all the years of study. However, 'Valleystar' yielded maximum per vine to the tune of 4.51, 4.25 and 4.38 kg in all the years of experimentation as well as in pooled analysis and was highly enriched with total soluble solids. Nevertheless, 'Oscar' turned out to be the highest yielder per square meter producing 13.34, 12.29 and 12.81 kg in 2014, 2015 and in pooled analysis, respectively. 'Fantasy' also displayed the height value for ascorbic acid (3.05 mg) in pooled analysis. Subsequently, economic analysis of the study identified 'Oscar' as highly remunerative cultivar exhibiting BCR of 1.05 with net realization of Rs. 80518.00, which was immediately followed by 'KUK 9', 'RS 03602833' 'Kian' and 'Valleystar'. Furthermore, a higher BCR of 1.63 or 1.75 could be expected at farmers’ level with 65% or 75% subsidy being disseminated by Govt. of Gujarat.
