Parmar University of Horticulture and Forestry, Nauni- Solan, H.P. The experiment was laid out in randomized block design with nine treatments and three replications. The experiments were conducted for two years in pea and tomato cropping sequence where in, recommended dose of fertilizer was substituted with organic at three levels (10, 20 and 30 per cent). The higher rates of fertilizer in the tune of 10, 20 and 30 per cent over recommended dose has also been tried to arrive at concrete and conclusive results. Integrated use of inorganic fertilizer along with FYM, vermicompost and PGPR improved physico-chemical, microbiological properties of soil and yield of pea and tomato cropping sequence. The addition of 80% NPKM + 20% N through FYM and VC (50:50) (T3) recorded highest (162.27 q/ha-Pea, 606.51 q/ha –Tomato) crop yield. The increase in yield of pea and tomato crops was found to be 23.29 and 29.60 per cent over recommended dose of fertilizers (T5), respectively. Higher uptake of major nutrients and good quality of pea and tomato fruits has also been recorded with 80% NPKM + 20% N through FYM and VC (50:50) treatment. The higher B:C ratio (3.08:1 and 5.48:1) was found with the substitution (up to 20 %) inorganic fertilizers with organics. Thus, a saving of about 20 per cent inorganic fertilizer can be achieved through organic substitution besides appreciable improvement in physico-chemical properties, microbiological properties, crop yield and quality of pea-tomato.ennullThesis
