The variety MNK 1 showed better storage performance as compared to KAK 2. Among the seven different treatments viz; control, polymer 10 ml/kg seed, polymer 20 ml/kg seed, vitavax 3 g/kg seed, polymer (10 ml/kg of seed) + vitavax power (3 g/kg of seed), polymer (20 ml/kg of seed) + vitavax power (3 g/kg of seed) and castor oil (10 ml/kg seed) the kabuli chickpea seeds treated with polymer (20 ml/kg of seed) + vitavax power (3g/kg of seed) recorded significantly higher protein content (17.92%), reducing sugar (1.28%), non-reducing sugar (9.90%) and dehydrogenase activity (0.740 OD value) upto nine months of storage followed by the treatment combination polymer (10 ml/kg of seed) + vitavax power (3 g/kg of seed). Hence the same treatment combination can be to store seeds for longer period without much deterioration. Keywords: polymercoat, fungicide, kabuli, biochemical constituent Introduction Among the food crops, pulses are an important group which occupies a unique position in the world of agriculture by virtue of their high protein content. In pulses, chickpea (Cicer arietinum L.) is one of the important crops with high acceptability and wider use, besides being rich in protein, its ability to use atmospheric nitrogen through biological nitrogen fixation is economically sounder and environmentally acceptable grown in Rabi season, which belongs to the genus Cicer, family Fabaceae. The southeastern part of Turkey near Syria was the place where chickpea is accepted to have been originated (Van Der Maesen, 1984) [7] . Kabuli chickpea accounts for about 20 per cent of the world’s chickpea production. Kabuli types are characterized by large seeds (more than 26- 50g per 100 seeds) that are pale cream and shaped like a ram’s head or brain. Kabuli chickpea seed is sought for whole seed consumption in confectionery products, salads, savoury meals or ground into paste (hommos); hence its appearance (size and colour) is an important characteristic that can affect marketability and price. One of the major problems encountered in kabuli chickpea production in India is lack of availability of good quality seeds at the time of planting as many of the seed lots produced losess their viability quickly. The post maturation and storage phases of seed encompass a series of deteriorative processes that can alter seed performance potential. Seed coating especially film-coating, is one such technique which has gained commercial importance owning to its practical utility as an effective delivery system for seed protectant and fortifying chemicals. Film coating is a new concept in which the plasticizer polymer forms a flexible film that adheres and protects fungicide and insecticide. The polymer coating is simple to apply, diffuses rapidly and non- toxic to the seed during germination. An experiment was conducted to determine the protein, sugars and dehydrodenase activity with kabuli chickpea varieties. The poor storability of kabuli chickpea seeds is accounted for high protein and sugar content, physiological fragility and thin seed coat, which leads to rapid loss of viability and vigour in storage and ultimately results in poor establishment of the crop in the field and low productivity. Seed deterioration is an irreversible, inexorable and inevitable process. But the rate of seed deterioration could be slowed down either by storing the seeds under controlled conditions or by imposing seed treatment with polymer coating along with seed treatment chemicals. Seed coatings are extremely thin, which allows multiple layers on the seed with only a 1 to 10% increase in seed weight. The film coat provides a uniform, yet precise placement of chemicals at much lower rates than the traditional seed treatment systems and
