Abstract
An experiment was conducted to evaluate parthenocarpic cucumbers under polyhouse at the Hi-tech Horticulture Unit, University of Agricultural Sciences, Dharwad, Karnataka during winter season of 2016-17. Ten parthenocarpic cucumber hybrids viz, Poyraz, Falcanostar, Sahin, Shinefit, Kingstar, Meltum, KPCH-1, Bahar, Cengel and Multistar were evaluated in completely randomized design replicated thrice.
Result revealed that, among ten hybrids Kingstar recorded higher vine length (110 cm, 252 cm and 276 cm) at 30, 60 and 90 DAT, respectively. Kingstar recorded higher internodal length, fruit length and fruit weight (8.17 cm, 17.90 cm and 161.67 g, respectively). Less number of days taken to first flower emergence, days taken to first harvest and last harvest and more fruit diameter was recorded in KPCH-1 (20.67 days, 31.40 days, 78 days and 3.70 cm respectively). Multistar recorded significantly higher number of fruits per vine (37.33), yield per vine (5.21 kg), yield per hectare (231.18 ton) which was followed by hybrid Bahar yield per vine (4.32 kg), yield per hectare (191.96 t/ha). Maximum shelflife (6.80 days) and less moisture content (95.15%) was recorded by Multistar.
The significantly more TSS (3.33 0B) content was recorded in KPCH-1, whereas, higher titrable acidity (0.51%) was in Poyraz which was followed by hybrid Multistar (0.35%). The maximum ascorbic acid and firmness (4.47 mg/g and 7.17 kg/cm2) was recorded in Sahin. The gross return (` 1,73,400), net return (` 1,18,421) per 500 m2 was significantly higher in the Multistar which was followed by Bahar gross return (1,44,000), net return (` 90,982). With respect to benefit cost ratio, Multistar (3.15) was found to be superior over the other hybrids.
The results of present investigation indicated that the hybrid Multistar was suitable hybrid and highly economic under polyhouse.
