Use of Bio-fertilizers in Vegetable Production

Bio-fertilizers have definite advantage over chemical fertilizers. Chemical fertilizers supply over nitrogen whereas bio-fertilizers provide in addition to nitrogen certain growth promoting substances like hormones, vitamins, amino acids, etc, crops have to be provided with chemical fertilizers repeatedly to replenish the loss of nitrogen utilized for crop growth. Bio-fertilizers application in agriculture will have greater impact on organic agriculture and also on the control of environmental pollution, soil health improvement and reduction in input use. Farmers try to increase yields of vegetable crops by mean of heavy nutrition's. The use of chemical nitrogen and phosphorus fertilizers at high levels had an adverse effect on the accumulation of NH₄⁺, NO₃⁻, NO₂⁻ and PO₄⁻ in vegetable product tissues. Therefore, clean agriculture recently depends upon using bio-fertilizers as well as organic in order to produce high yields with the best commodity quality without contamination and less accumulation with heavy metals.
