Phosphorus is a major and essential nutrient for plant growth and it is sparingly soluble in nature. About 98 per cent of the Indian soil has inadequate supply of phosphorous. It plays a vital role in the process of photosynthesis and energy transformation and is the second major plant nutrient after nitrogen in terms of quantitative requirements for plants. Most of the Indian tropical soil lack required quantity of phosphorus for the growth of plants. The seed of Foxtail Millet SiA-326 variety were sown in earthen pots (15 cm in diameter) containing 3kg of sterilized soil. The soil was mixed in the ratio of 1:1 (One part of garden soil + one part of pure sand). 15 g of VAM (Glomus fasciculum) inoculum, 10 ml of half strength phosphorus less Hoagland solution was given per pot with the seedlings, at the interval of 15 days. The study showed that different levels of superphosphate with mycorrhiza enhanced the plant height and ‘P’ uptake. It is concluded that, inoculum of the respective efficient AM fungi in Foxtail Millet SiA-326 variety supplemented with 75% is recommended ‘P’ fertilizer would save 25% of ‘P’ fertilizer.
