There are numerous disadvantages of chemical fertilizer as the soil can take really long to replenish and attain its natural form. Soil need to be fit as it is most important factor for growth of plant. Due to the decrease in soil quality farmers have started using alternate substances such as biofertilzers which provide right amount of nutrients and are eco-friendly.

In this study thirteen isolates of Burkholderia sp. were isolated from the root, stem and leaf samples of four different crops viz., rice, maize, sugarcane and blackgram, using N-free Burkholderia Azelaic acid (BAz) semi solid medium. Based on growth performance on different media the following isolates viz., RB1 (Rice Burkholderia 1), MB2 (Maize Burkholderia 2), SB3 (Sugarcane Burkholderia 3) and BB4 (Black gram Burkholderia 4) were selected for further studies.

A field was conducted at Experimental Farm, Agronomy Section, College of Agriculture, Latur. The experimental field was levelled and well drained. The soil was medium and black in colour with good drainage. The soil was clayey in nature and slightly alkaline (7.8) in reaction, low in nitrogen (118.86 kg ha-1 ), medium in available phosphorus (17.7 kg ha-1 ) and rich in available potassium485.89 kg ha-1 ). The environmental conditions were favorably congenial for normal growth and maturity of pigeonpea crop.

Biologically active product more appropriately called as “microbial inoculants” contains active strength of selective microorganisms like bacteria, algae, fungi; alone or in combination helps in increasing crop productivity by biological nitrogen fixation. Biological nitrogen fixation , the second most important biological process on earth after photosynthesis involves conversion of atmospheric nitrogen (N2) to ammonium, a form of nitrogen that can be utilized by plants The rhizobia are a group of Gram-negative bacteria that form speciesspecific symbioses with legume plant.

The aim of this study was to study the use of a beads-based biofertilizer in crop production. The study focuses on the production of a beads-based biofertilizer containing spores and vegetative cells of Bacillus megaterium (B. megaterium) VACC 118. It also evaluated the quality of the biofertilizer and its effects on the growth and yield of cabbage. The results show that the density of B. megaterium in the beadsbased biofertilizer reached 4.34×1010 CFU/g and did not change after 6 months of storage. The degree of swelling of the beads was 1.

The degradation of soil wellbeing is one of the most important predicaments to the farming community. There are several reasons for the loss of soil health. One among such issue is uncontrolled use of chemical fertilizers in agriculture ultimately worsen physical, chemical and biological properties of soil. Consequently, alternate solutions to overcome soil degradation, especially agricultural land, the natural way of farming came into existence. The concept of organic farming is mainly to utilize biofertilizers, farmyard manure, compost, vermicompost, green manuring, panchakavya, etc.
