Description The present investigation entitled “Studies on the effect of phenotypes and different levels of nitrogen on growth and yield of kakrol ( Momordica dioica Roxb.)” was carried out during the kharif season of 2013-2014 at Horticultural College and Research Institute, Venkataramannagudem, West Godavari District of Andhra Pradesh. The study was carried out with 9 different treatments involving different combinations of different phenotypes and levels of nitrogen. The experiment was laid out in a randomized block design (RBD) with factorial concept replicated thrice and data on the effect of different phenotypes and nitrogen treatments on growth, yield and economics were recorded and statistically analyzed.
The influence of different phenotypes on plant growth parameters like number of primary branches, number of nodes per plant were significant and showed highest values in vines with single lobed leaves. On the other hand the lowest values were recorded on parameters viz., number of days taken to appearance of first female flower and node at which first female flower appear was lowest in vines with single lobed leaves. The yield contributing parameters like fruit length, number of fruits per plant, mean fruit weight, net plot yield, estimated fruit yield, fresh seed weight and nitrogen uptake were recorded highest in vines with single lobed leaves.
Among the nitrogen levels, the higher values for plant growth parameters with respect to length of main shoot at last harvest, number of branches at last harvest, internodal length, number of days taken for appearance of first female flower, number of nodes per plant at harvest and days to last harvest were recorded with the application of 375 kg N ha-1. The yield contributing parameters like number of fruits per plant, mean fruit weight, net plot yield, estimated fruit yield and fresh seed weight, nitrogen uptake were also recorded higher with the nitrogen application of 375 kg N ha-1 .
Among the different interaction effects between phenotypes and nitrogen levels showed significant influence in most of the growth and yield characters viz., number of primary branches at last harvest, number of fruits per plant, maximum net plot yield, estimated fruit yield. However, fruit length, fruit diameter, mean fruit weight, number of seeds per fruit, seed weight per fruit and quality parameter i.e., ascorbic acid did not differ significantly. The gross returns and net returns recorded maximum vines with single lobed leaves with application of 375 kg N ha-1 resulting in a maximum benefit-cost ratio of 2.18.
Among the different treatment combinations, it was found that the treatment combination vines with single lobed leaves with application of 375 kg N ha-1 proved to be the best and economical for cultivation of kakrol under light soils of coastal Andhra Pradesh.
