Effectiveness of Thuja 30 in the Management of Rhizoctonia Leaf Blight in Amaranthus Tricolor

Abstract

In the work the Genotypic variability in vegetable Amaranth(Amaranthus tricolor) for foliage yieldand its contributing traits over successive cuttings and years it is clearly written about the importanceof this plant as an agricultural crop. Amaranthus species are being cultivated since centuries as a leafy vegetable, as well as an important subsidiary food crop in many parts of the world. Vegetable amaranth serves as an alternative source of nutrition for people in developing countries since it is a rich and impressive source of carotenoid,protein, vitamins and dietary fibers. Unlike otherleafy vegetables, vegetable amaranth is cultivated during hot summer months when no other green vegetables are available in the market. Besides immense nutritional importance, it can also be successfully grown under variedsoil and agro climatic conditions. Recently current interest in amaranth also resides in the fact that it has a great amount of genetic diversity andphenotypic plasticity. Amaranth is extremely adaptable to adverse growing conditions, resistsheat and drought, has no major disease problems and is among the easiest of plants to grow. In this study the protein and carotenoid content of the leaves was found to be about 1.24 ±0.03mg/100mg and 0.03±0.02mg/100g respectively. The leaves of Amaranthus tricolor also have considerable quantities of ascorbic acid. The variations in the values of genotypic coefficient are noted in successive cuttings. The highest expected genetic advance was noticed for ascorbic acid followed by foliage yield and leaf size.
