Effect of Organic Formulations and Growth Regulators on Seed Quality of Bitter Gourd (Momordica charantia L.)

Abstract

A research was conducted to evaluate the effect of plant growth regulators and organic formulations on seed quality parameters of bitter gourd during 2022-23 and 2023-24. Three growth regulators and three organic formulations including control (T0) making sixteen treatments (sole application and combination of growth regulators and organic formulations) were tested. These were evaluated under randomized block design on ‘Jaunpur Long Green’ variety. All the treatments were applied as foliar spray with hand sprayer at 3-4 leaf stage of the plants. The seed quality parameters were tested in the seed testing laboratory of Seed Science and Technology department of C S Azad University of Agriculture and Technology, Kanpur. The results obtained indicated that various treatments gave significantly better results as compared to control for all the seed quality parameters studied. In the results it was found that standard germination (85.67%), speed of germination (24.25), seedling length (29.53 cm), seedling dry weight (123.77 mg), vigour index-I (2529.13) and vigour index-II (10602.97) were maximum with the treatment Panchgavya @ 5% + Cycocel @ 200 ppm (T11) which was closely followed by Panchgavya @ 5% + Ethrel @ 200 ppm (T10). However, the lowest values for all the parameters were recorded with the control (T0). Thus, it is clear that the use of organic formulations in addition to application of growth regulators as foliar spray is beneficial for improving the quality of the bitter gourd seeds.
