Variation and Character Association in Seed Yield and Related Traits in Rice Bean (Vigna umbellata)

The genotypic response of the growth, yield and quality traits of rice bean [Vigna umbellata (Thunb.) Ohwi and Ohashi] to NPK enrichment was studied in relation to different fertilizer treatments. The treatments consisted of three NPK levels, namely 0:0:0 (T0) control, 10:30:10 (T1) and 20:60:20 (T2) kg/ha. There were significant differences in plant height 115 days after sowing, days to maturity and tryptophan content (g/16 g N) in various rice bean genotypes with different fertilizer levels. Higher seed yields were recorded for the genotypes JCR-20(S), IC-140796, IC-019352 and JCR-152 as compared to the check variety (BRS-2). The fertilizer treatments significantly affected growth, yield and its contributing traits: plant height, number of pod clusters/plant, seeds/pod, seed yield/plot and total pods picked at maturity. Little variation was observed between the fertilizer treatments for the crude protein (%) and methionine (g/16 g N) contents, but significant variation in the tryptophan content was detected for genotype LRB-40-2. Seed yield and its contributing traits responded positively to the fertilizer treatments. Among the three fertilizer treatments tested in the experiment, the T2 treatment was found to be promising for increasing seed yield. Thus, it can be concluded from the study that the rice bean crop is responsive to fertilizers and that the application of optimal levels of NPK could enhance its productivity.

Rice bean, a lesser known pulse, has excellent nutritive value. The seed yield of the crop is higher as compared to other pulses of the Vigna family. In the present study thirty diverse rice bean genotypes were evaluated for nutritional and morpho-physiological characteristics for selecting overall superior genotypes. Variations were observed for crude protein (16.1–19.12%), carbohydrates (59.28–76.89%), ascorbic acid (0.19–0.80 mg/100 g), crude fibre (4.23-6.0%), limiting amino acids, namely tryptophan (0.85–2.42 g/16 g N) and methionine (0.52–0.67 g/16 g N), and ether extract (0.57–2.13%). Anti-nutritional factors, such as total phenolics, total tannins, condensed tannins, hydrolysable tannins and α-amylase inhibitor, also varied to a considerable extent. The cumulative grading of the genotypes based upon nutritional and morpho-physiological attributes revealed that the genotypes JCR-76, IC-137200, IC-140796 and IC-137189 were nutritionally superior genotypes for consumption.

Orphan Crop

AbstractRice bean (Vigna umbellata) is a legume that belongs to Vigna genus. Native to Indo-Chinese region, it is considered to be an ‘under-utilized’ or ‘orphan’ crop. Rice bean is known to possess high nutritional potential and antioxidant activity. But the use of rice bean supplementation in routine diet is limited despite its high nutritional profile due to the presence of non-nutritional factors. Thus, various pre-treatments like soaking, germination, oven roasting, sand roasting, boiling and pressure cooking at different time and temperature were carried out to reduce the anti-nutritional content of rice bean and to study its effect on antioxidant activity and phytochemical content. All the pre-treatments were able to significantly reduce the anti-nutrient content in rice bean, but germination showed the maximum reduction. Also germinated rice bean showed the maximum antioxidant potential and maximum content of total phenols, total flavonoids, vitamin C and carotenoids. Rice bean has been underutilized so far, owing to its antinutrient content and low popularity. This experiment attempted to use low cost processing to reduce the content of antinutrients and track the antioxidant content in rice bean. The concluded processing could be adopted for commercial applications for dietary supplementation.
