Abstract:
A field experiment was conducted to study the combined effect of Potassium and Gibberellic acid on quality parameters in parthenocarpic cucumber (Cucumis sativus L.) cv. Sania (F1) under low poly tunnel. This experiment was carried out under low poly tunnel during 2019-20 and 2020-21 at Centre of Excellence on Protected Cultivation and Precision Farming, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.). The experiment was laid out in a Factorial Randomized Block Design replicated thrice with ten treatments i.e. Control (Water spray), T2 - (Potassium 1000 g.dm^-3 + GA₃ 5 g.dm^-3), T3 - (Potassium 2500 g.dm^-3 + GA₃ 5 g.dm^-3), T4 - (Potassium 5000 g.dm^-3 + GA₃ 5 g.dm^-3), T5 - (Potassium 1000 g.dm^-3+ GA₃ 10 g.dm^-3), T6 - (Potassium 2500 g.dm^-3 + GA₃ 10 g.dm^-3), T7 - (Potassium 5000 g.dm^-3 + GA₃ 10 g.dm^-3), T8 - (Potassium 1000 g.dm^-3 + GA₃ 15 g.dm^-3), T9 - (Potassium 2500 g.dm^-3 + GA₃ 15 g.dm^-3), T10 - (Potassium 5000 g.dm^-3 + GA₃ 15 g.dm^-3). The result shows that maximum protein was recorded (27.20% and 29.80%) in T7, maximum total sugar was recorded (33.38% and 33.68%) in T10, maximum reducing sugar was recorded (6.87% and 6.82%) in T10, maximum non reducing sugar was recorded (26.52% and 26.29%) in T10, maximum ascorbic acid was recorded (3.07% and 3.08%) in T10 during both the year. It is concluded that among several treatments T10 was found superior over others in quality parameters such as Total Sugar, Reducing Sugar, Non-Reducing Sugar, Ascorbic acid and T7 was found superior over others in Protein.
