  1. WELCOME Wel Come Influence of Integrated Nutrient Management on Productivity of Summer Groundnut (Arachis hypogaea L.)Under Climate Change Condition F. G. Vala MAIN OILSEEDS RESEARCH STATION JUNAGADH AGRICULTURAL UNIVERSITY, JUNAGADH - 362 001.

  2. Introduction • Groundnut known as poor man’s almond. • Groundnut (Arachis hypogaea L.) is cultivated predominantly in the tropics and subtropics. • In India, it is cultivated on area of 5.53 M ha with production of 9.67 M tones and productivity of 1750 kg ha-1 during 2013-2014 (AICRPG, 2015). • In Gujarat, it is grown on 16.86 lakh hectares area with production of 27.17 lakh tonnes and 1662 kg ha-1 productivity. • The wide difference in productivity of groundnut in our country as compare to that in USA (3540 kg ha-1) and China (2664 kg ha-1). • During the summer season, there is a higher yield potential of groundnut in Saurashtra and Kutch region of Gujarat State.

  3. Among the various agronomic practices, nutrient management has an important role in maximizing the pod yield. • The situation has changed materially during the last decade with fast depletion of fossil fuel, naphtha resulting in exorbitant cost of chemical fertilizer. • The efforts should have to be made for proper utilization of costly chemical NPK fertilizers with their efficient use. • The reduction in NPK fertilizer can be fulfilled through supplementation with organic manures and bio fertilizers.

  4. Objective To study the effect of organic manures, inorganic fertilizers and bio fertilizers on growth, yield and quality of groundnut. To quantify the role of organic manures, inorganic fertilizers and bio fertilizers on uptake of nutrients by groundnut.

  5. MATERIALS & METHOD

  6. Treatment details

  7. Table.1 Effect of different treatments on pod and haulm yield of summer groundnut

  8. Table.2 Effect of different treatments on growth of summer groundnut

  9. Table.3 Effect of different treatments on yield attributes of summer groundnut

  10. Table.4 Effect of different treatments on quality of summer groundnut

  11. Table.5 Effect of different treatments on uptake of N, P, K and S by groundnut

  12. Table.6 Effect of different treatments on total uptake of N, P, K and S by groundnut

  13. Conclusion Based on field experimentation, it can be concluded that, higher growth, yield attributes, yield, quality and uptake from bold seeded summer groundnut can be secured by application of 75% RDF(18.75-37.50-37.50-15 kg N-P2O5-K2O-S ha-1) + 25% N through FYM (1.25 t ha -1) + Biofertillizer (Rhizobium and PSM @ 10 ml kg-1 seed) on calcareous clayey soil of South Saurashtra Agro-climatic Zone of Gujarat
