Effect of Conjunctive Use of Phosphorus and Bio-Organics on Phosphorus Content and Uptake in Summer Groundnut (Arachis hypogaea L.)

The groundnut (Arachis hypogaea L.) is one of the important food legume crops of tropical and subtropical parts of the world. It is the world’s most popular oilseed crop cultivated in more than 100 countries in all the six continents. Groundnut kernel contains above 40% edible oil, around 25% protein and 18% carbohydrates along with minerals and vitamins. Groundnut oil is free from cholesterol and contains less than 20% saturated fatty acid and hence is heart friendly. Groundnut oil is also considered as the staple and nutritive, as it contains just the right proportion of oleic (46.5%) and linoleic (31.4%) acids (Mathur and Khan, 1997). Phosphorus play beneficial role in the root development, nodulation and stimulation of the symbiotic nitrogen fixation. It enhances root development and nodulation, improves the supply of nutrients and water increase in photosynthetic area resulting in more dry matter accumulation and yield (Rajanikanth et al., 2008). Phosphorous appear to be a limiting factor in yield. It promotes root development, flowering and fruiting and aids in setting of kernels.
