The use of vitormone (Azotobacter chroococcum) a liquid bio-fertilizer along with chemical fertilizer on crop growth and yield of wheat (Triticum aestivum L)

Wheat (Triticum aestivum L) is widely cultivated as a staple food crop of the world as well as in India. However, due to continuous use of chemical fertilizers the productivity is decreasing. Hence an experiment was conducted to study the effect of Vitormone (Azotobacter chroococcum) along with RDF at Agronomy Division, I.A.R.I. New Delhi. Results compiled indicated that application of Vitormone @ 2.0 ml/L along with RDF significantly increase tillers/m² (49.17%), productive tillers/m² (56.50%), ear length (32.18%), spikelets/ear (25.86%), grains/spikelet (29.72%), straw yield (53.77%), 1000 grain weight (21.80%), protein content (20.62%) and yield (78.10%) over control and 8.57% over RDF. Similarly, foliar nitrogen nutrition by Vitormone (Azotobacter chroococcum) can reduce 25 % nitrogen dose and increase yield by 47.02 % to 61.02 % over control and on par results with RDF. Also, spraying of Vitormone did not show any phyto-toxic effect on wheat plant.
