INFLUENCE OF CALCIUM PHOSPHATE NANO GEL FERTILIZER COMPOSITES ON GERMINATION OF CROP PLANTSR. UMARANI AND R. MALA
Agriculture is the backbone of Indian economy. At present the contribution of agriculture to Indian economy is steadily decreasing due to rapid Industrialization. Population explosion and its consequence of increased demand for food urge Science and Technology to devise an alternative strategy to increase agricultural productivity with limited availability of land and water resources. In the present study, the influence of Calcium Phosphate Nano Gel Fertilizer Composites (CAPNGFC), urea(10mg/L), diammonium phosphate(20mg/L) and dipotassium hydrogen phosphate(20mg/L) Fertilizer Composites (FC) and Calcium Phosphate Nano Gel (CAPNG) on germination of four plants were evaluated. CAPNG was synthesized and the size and the morphology was determined by SEM. 1in 5 dilution, 1in 10, 1in 15 and 1in 20 dilutions of CAPNGFC was also used to assess their influence on germination of Oryza sativa, Arachis hypogea, Abelmoschus esculentus and Amaranthus spinosus. Seed germination was 85%,88% and 90 % respectively in O. sativa, A.hypogea and A. spinosus etc. in control. CAPNGFC increased the germination to 95%,95% and 97% in the above plants respectively. 1 in 20 diluted calcium phosphate nanogel has no stimulatory role.
