Growth and Yield of Bitter Gourd as Influenced by Gibberellic Acid and Naphthalene Acidic Acid (Momordica charantia L.)

Abstract

An experiment was carried out in the departmental field of Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during February to May 2021 on bitter gourd (Momordica charantia L.) to find out the best treatments of plant growth regulators for better growth and yield in bitter gourd. The experiment include growth regulators like GA3 and NAA with different ppm. Nine treatments were made and replicated thrice in randomized block design. Application of plant growth regulators was done as per the treatment allocation at four leaf stage. The experimental results revealed that treatment 25 ppm GA3 was found most effective in terms of vine length and results maximum at 20,40,60 and at harvest, and days to first appearance of male flowers whereas treatment T8 NAA 150ppm was recorded significantly minimum at days to first harvest (57.267) and maximum in fruit weight (134.933), fruit length (14.107), fruit diameter (4.453), No. of fruits per plant (11.867), average yield per plant (1,609.100), yield tonne per hectare (10.725).

Effect of Plant Growth Regulators on Growth, Fruit Yield and Quality of Kharif Season Bitter Gourd (Momordica charantia L.)

“…The maximum average fruit weight (g) of Bitter gourd due to treatment 12 might be due to fact that NAA regulate the growth by causing cell division and cell elongation in plant system. These results are in conformity with Rajashree and Deepanshu [13]. While the minimum value in treatment T0 (control) may owes to its inhibitory effect because this treatment occupy only recommended dose of fertilizers in bitter gourd.…”

Effectiveness of different combinations of urea and vermicompost on yield of bitter gourd (Momordica charantia)

“…Bitter gourd ( Momordica charantia L.) is the Neglected and Underutilized Cucurbit Species (NUCuS) of the cucurbitaceae family with somatic chromosome number 22 and is raised for its unripe tuberculate fruits, which have a distinctively bitter flavor [ [1] , [2] , [3] , [4] , [5] , [6] , [7] ]. It is a lush, climbing vine with somewhat silky stalks adorned with deeply lobed, dark green leaves and yellow dioecious blooms [ 4 , 8 , 9 ]. Bitter gourd domestication most likely originated in Eastern Asia, particularly in the eastern part of India or the southern zone of China [ [10] , [11] , [12] ].…”
