Abstract

Cereals and millets occupy an important place in the grain economy. The millet tenai Setaria Italica (Italian millet) is used as an important food source by the poorer class of people in India. This is known to promote a very low growth rate in rats as their proteins are found to be deficient in certain essential amino acids. So in this study an effort was made to improve the nutritional quality of tenai by germination. The study was also extended to find out the nutrient loss on cooking.

Abstract

Grape growers of Andhra Pradesh, who raised cv. Thompson Seedless on own ischolar_mains are switching over to the practice of grafting on dogridge (Vitis champani) ischolar_mainstock. Own ischolar_mained vines differ from the grafted vines in their uptake of nutrients. Hence, there is a need for a separate nutrient management technique in case of own ischolar_mained and grafted vines for maximizing vine growth, production and fruit quality. Therefore, nutrient survey was conducted in vineyards around Hyderabad for three successive years 2005-08, to determine the difference in petiole nutrient accumulation of cv. Thompson Seedless grafted and own ischolar_mained vines at bud differentiation and full bloom stage. Petiole samples were collected from vineyards growing Thompson Seedless (Vitis vinifera L.) grape cultivar on own-ischolar_mains and grafted on dogridge at bud differentiation and full bloom stages, in order to determine the concentration of N, P, K, Fe, Mn, Cu and Zn. The results indicated that, regardless of the phenological stages and years, there were a consistent decrease in mean petiole P content from 0.91 per cent ± 0.19 and 0.76 per cent ± 0.17 in own ischolar_mained vineyards to 0.73 per cent ± 0.21 and 0.59 per cent ± 0.17 in vineyards grafted on dogridge ischolar_mainstock at bud differentiation and full bloom stages, respectively. On contrary there was consistent impact on mean petiole K content which increased from 2.18 per cent ± 0.47 and 2.85 per cent ± 0.52 in own ischolar_mained vines to 2.80 per cent ± 0.69 and 3.29 per cent ± 0.81 on dogridge ischolar_mainstock at bud differentiation and full bloom, respectively. In case of N the trend was not consistent. With regards to micronutrients there was a slight but consistent increase in Mn and Fe content at bud differentiation and Zn content at full bloom on dogridge when compared to own ischolar_mains. The mean petiole content except K and Cu content was lesser at bud differentiation as compared to full bloom stage.
