Influences of Different Sowing Dates with Application of GA3 on Germination and Seedling Growth of Cape Gooseberry (Physalis peruviana L.) in Subtropical Condition Prayagraj

The present investigation was carried out to find influences of different sowing dates with application of GA3 on germination and seedling growth of Cape gooseberry (Physalis peruviana L.) in subtropical condition Prayagraj. The experiment was conducted in a Complete Randomized Design with three replications during August-March (2022-23) at Horticultural Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences Prayagraj Uttar Pradesh India. The 10 treatments comprised of five dates of sowing i.e., T1: 20 August 2022 with seed treatment from GA3 @100ppm, T2: 20 August without seed treatment from GA3, T3: 5 September 2022 with seed treatment from GA3 @ 100 ppm, T₄: 5 September without seed treatment from GA3, T5: 20 September 2022 with seed treatment from GA3 @100ppm, T6: 20 September 2022 without seed treatment from GA3. T7: 5 October 2022 with seed treatment from GA3 @100ppm, T8: 5 October 2022 without seed treatment from GA3, T9: 20 October 2022 with seed treatment from GA3 @100ppm, T10: 20 October 2022 without seed treatment from GA3. From all the above treatments the highest percentage of germination was recorded from T7: 93.33% followed by T8: 90% and T10: 91.66% and vegetative growth of seedling was higher in T7 followed by T8 and T9. All the treatments are sown in nursery through seed propagation after that transplanted in main field level for observe germination parameters and vegetative growth of Cape gooseberry seedling influenced by different sowing dates.
