Grafting method in vegetables has been used in common due to positive effects in agriculture. In this context, it is focused that the studies aimed at increasing yield and quality through grafting. This research was carried out to determine the effects of grafting bitter gourd (Momordica charantia L.) onto pumpkin (Cucurbita maxima). Effects of grafting on extract yield, dry matter ratio, ash, and macro and micro elemental content of the fruits and leaves of bitter gourd were determined in greenhouse conditions. Grafting significantly increased the dry matter ratio and extract yield in the bitter gourd fruits and the ash content in young, mature and old leaves. In the fruits, a positive correlation (R = 0.9264) was found only between extract yield and dry matter ratio. The main important effect of grafting in terms of macro and micro elements appeared on the fruits of bitter gourd. The accumulation of Ca2+ in the leaves increased during maturation. The positive effect of grafting in terms of Ca2+ increase in fruits was higher in unripe fruits compared to ripe fruits. In addition to obtaining more extracts from the fruits bitter gourd, the enrichment of its fruits in terms of Ca2+ and K+ and its leaves in terms of Ca2+ increases the importance of these parts in terms of human nutrition.

Seventeen genotypes of bitter gourd (Momordica charantia L.) were studied in a field experiment conducted at the experimental field of Sher-e-Bangla Agricultural University, Dhaka, during April 2009 to September 2010. The objectives of the study were to measure the variability among the genotypes for yield and yield contributing characters, estimate genetic parameters, association among the characters and their contribution to yield. There was a great deal of significant variation for all the characters among the genotypes. Considering genetic parameters high genotypic co-efficient of variation (GCV) was observed for branches per vine, yield per plant and number of fruit per plant whereas low genotypic co-efficient of variation (GCV) was observed for days to first male and female flowering. In all the cases, it was found that phenotypic co-efficient of variation was greater than genotypic co-efficient of variation. Highest genotypic and phenotypic co-efficient of variation was observed in branch per vine, fruit length, fruit weight and number of fruit plant which indicated a wide variability among the genotypes and offered better scope of selection. The results obtained showed that fruit length showed low direct and positive effect on yield per plant and indirect positive effect on yield per plant via fruit diameter and average fruit weight. Similar result was found for fruit diameter. Average fruit weight and number of fruits per plant showed high direct and positive effect on yield per plant. Path analysis revealed that average fruit weight, number of fruits per plant, days to male flowering and fruit length had positive direct effect on fruit yield. Considering group distance and the agronomic performance, the inter genotypic crosses between G2& G5; G2&G14; G14&G15; G2&G15; G10&G11; G10&G13; G11&G13; G5&G15; G5&G14 might be suitable choice for future hybridization programme.Bangladesh J.

The yield and quality of an annual crop are highly dependent on uniform and rapid germination of the seeds. In case of bitter gourd (Momordica charantia), the germination and field emergence is always a problem as seeds have thick and hard seed coat. Pre-sowing hydro-priming is one of the most suitable, affordable, easily available, and cost-effective techniques in breaking down seed dormancy to enhance germination. Hence, a field experiment was conducted in Surkhet district of Nepal 2020 to assess the effect of different hydro-priming duration on germination and seedling growth of bitter gourd. The experiment was laid out in single factor Randomized Complete Block Design (RCBD) with four replications and seven treatments including different hydro-priming durations (T0: control, T1: 6 hours, T2: 12 hours, T3: 18 hours, T4: 24 hours, T5: 36 hours and T6: 48 hours) of bitter gourd seeds of Palee variety, the most popular variety among the farmers. The highest water uptake and germination were found in 48 hours of seed hydro-primed seeds whereas the lowest water uptake and germination were observed on non-primed seeds. Similarly, the tallest seedling, most vigorous seedling in terms of seedling vigour index I and II was observed in 48 hours hydro-primed seeds followed by 36 hours of seed hydro-priming and shortest seedling and the least vigorous seedling in control. Thus 48 hours of seed hydro-priming was found to be effective for increasing germination and seedling growth in bitter gourd, which needs to be further investigated under large, open-field conditions with different varieties.
