Scholor, Department of Agricultural Economics, College of Agriculture, University of Agricultural Sciences, Dharwad, Karnataka, India Resource use efficiency of Greengram in Gadag district of Karnataka Sangamesh Angadi and BL Patil Abstract The present study attempted to estimate the cost of cultivation of Greengram in the Gadag district of Karnataka. The multi-stage random sampling procedure was adopted to choose the sample farmers. Thus, the total sample size selected for the present study was totaled to 180. The data pertained to the agricultural year 2014-15. Tabular analysis techniques were used to analyze the data. The results revealed that the variables included in the function explained 79 per cent, 90 per cent and 86 per cent variation in the dependent variable on small, medium and large farmers respectively. Increasing returns to scale were observed for medium (1.05) and large farmers (1.03), whereas decreasing returns to scale was observed for small farmers (0.96). Here large farmers getting more returns to scale compared to other categories of farmers because of operation of economies of scale and proper management of resources in the production process. The ratio of Marginal Value Product (MVP) to Marginal Factor Cost (MFC), it revealed that allocative efficiency was positive and greater than unity in the case of seeds, manures, human labour, and PPC indicating that still there was scope to use these inputs and increase the gross returns of greengram production in the study area. Keywords: Categories of farmers, resource use, marginal value product and marginal value cost Introduction Greengram (Vigna radiata L) is belongs to the family Leguminosae and sub-family Papilionaceae and the earlier name of Greengram was Phaseolus aureus that has now been changed to Vigna radiata. It falls in the group of Asiatic Species of genus Phaseolus. The Greengram was domesticated in India, where its wild progenitor (Vigna radiata subspecies sublobata) occurs wild. Archaeological evidence has turned up carbonized Greengram on many sites in India. Areas with early finds include the eastern zone of the Harappan civilization in Punjab and Haryana, which dates back about 4500 years, and in South India modern in state named Karnataka it finds date back more than 4000 years. However in South India there are evidences for evolution of larger-seeded greengram about 3500 to 3000 years ago. And greengram were widely cultivated throughout India, Later cultivated greengram spread from India to neighbouring countries like China and Southeast Asia. Nutritional and Medicinal value Greengram contains about 24 per cent protein, this being about two third of the protein content of soybean, twice that of wheat and thrice that of rice. The protein is comparatively rich in lysine, which is deficient in cereal grains. Hence, a diet combining mungbean and cereal grains forms a balanced amino acid diet. Every100 g of mungbean seeds contains 132 mg calcium, 6.74 mg iron, 189 mg magnesium, 367 mg phosphorus and 124 mg potassium and vitamins like 4.8 mg ascorbic acid, 0.621 mg thiamine, 0.233 mg riboflavin, 2.251 mg niacin, 1.910 mg pantothenic acid and 114 IU vitamin A (Haytowitz and Matthews, 1986). Greengram has high digestibility and palatability, its pods are used as green vegetable. Its whole grains and split grains are used as dal and curry. Being highly digestible, its curry is generally recommended for patients. Its flour is used in various preparations like, halwa, savoury dishes, snacks, pakoras and fried dal, to get very delicious and nutritious products. Its green plants, chopped and mixed with other fodders are palatable feed for animals. It is also used as green manuring crop, which adds nitrogen in addition to humus to the soil. It is a soil protecting crop in rainy season. Cooked dal of green gram is a very digestive food for invalid and sick persons. Its regular use during childhood, pregnancy and lactation helps one to get the required nutrition and promote health. It is an aperients i.e. a laxative. When given in large quantities. The soup made from it is best article of diet after recovery from acute illness. Applying in the form of powder is useful in relieving the heat or burning of the eyes.
