Abstract
ABSTRACT
The present investigation entitled “Influence of integrated nutrient management on yield
and soil properties in pea- tomato cropping sequence” was conducted during 2014-15 and 2015-
16 at the experimental farm of Department of Soil Science and Water Management, Dr. Y.S. 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.
