Effect of Activated Charcoal on Growth, Yield, Quality and Disease Incidences of Parthenocarpic Hybrid Cucumber under Protected Condition

This study was carried out during the Rabi season 2023-2024 to investigate the effect of different levels of activated charcoal on the growth, yield, and quality of Parthenocarpic hybrid cucumber variety SFC-2125 (FITO) and to estimate the economics of crop. The research revealed that activated charcoal had significant effect on Treatment-5 (5g activated charcoal per plant) which performed best in terms of growth parameters with maximum Vine length 136.39 cm, number of nodes 17.52, maximum chlorophyll content 57.68, shortest duration for flowering 31.30 days and fruit setting 33.41 days, maximum number of female flower per plant (46.50), fruits per plant (37.67), fruit length(16.82cm) , number of fruit yield per plot 19.10 kg, and dry matter content (5.88%). The highest benefit cost ratio was at 3.86 in the same treatment.
