EFFECT OF FERTONIC (BIO-0RGANIC SOIL ENRICHER) ON THE GROWTH AND YIELD OF POTATO
R, C, SHARMA AND M.C.SOOD, CENTRAL POTATO RESEARCH INSTITUTE SHIMLA 171 001 (HP)
Field experiments were conducted during 1996 0n Cultivator’s fields in shimla region On slightly acidic soil varying in soil organic matter to study the effects of FERTONIC ( Bio-organic Soil enricher ) on potato. The results shows that the fertonic had a positive effect on the growth and yield of potato when its level was raised from 250 to 500 kg/ha. . Its effect was more pronounced at 75% and 100% NPK application than at 50% NPK Application. However the Application of fertonic (500 kg/ha) and FYM at 30 t/ha could not substitute given 50% NPK. The data also indicated that it could substitute p and k by about 50 percent and could not substitute nitrogen fertilizer. The beneficial effect of fertonic was observed on both the soils containing low and high amounts of organic matter. Its application also induced early senescence by about 10 days and could help the crop to escape late blight disease of potato as well as could help in raising the cropping intensity.
