Abstract:
Pulses on account of their significant contribution in balancing the nutrition and strategic position in the bio-spectrum of the earth cannot be overlooked. These are only the richest source of proteins in the agricultural crop galaxy. Pulses are not only providing proteins to vegetarian community but also sustain the edaphic resources by virtue of their dynamic roots. The pulses constitute an association with Rhizobium bacteria living in their roots symbiotically. The field pea (Pisum sativum L.) crop is a high yielding, input responsive and relatively stable pulse crop of Rabi season that contributes significantly to the total pulses production of the country. It has high level of amino acids, especially lysine and tryptophan. Field pea inoculated with the appropriate strain of bacteria is able to fix a large portion of its nitrogen requirement from air in the soil through biological nitrogen fixation. Biological nitrogen fixation is an important nitrogen source due to the fact that it requires less energy and causes less environmental pollution. On the other hand inorganic fertilizers play a special role in crop production and are main suppliers of major plant nutrients (N, P and K). Intensive agricultural practices have resulted in numerous problems like micro nutrient deficiencies, nutrients imbalances, and deterioration of soil health and decline crop yield, Therefore, the rational and practical means to maintain soil fertility and to supply plant nutrient in balanced proportion, is to practice combined use of organic and inorganic sources of plant nutrients.
