Abstract
The present study entitled “Effect of integrated nutrient management on soil properties,
quality and productivity of broccoli” was conducted at research farm of Department of Soil Science
and Water Management, Nauni, Solan during the year 2022-23. The plot size was 2.25 m × 1.80 m
and a spacing of 45 cm × 45 cm. The research trial was comprised of eight treatments i.e. T1- No
application of manures and fertilizers (Absolute control), T2- Full recommended dose of NPK through
chemical fertilizer (as per package of practices), T3- FYM @ 10 t/ha + PGPR 0.2 l/plot + 75% through
chemical fertilizer, T4- FYM @ 10 t/ha + PGPR 0.2 l/plot + 50% through chemical fertilizer,
T5- FYM @ 10 t/ha + PGPR 0.2 l/plot + 25% through chemical fertilizer, T6- VC @ 2.5 t/ha + PGPR
0.2 l/plot + 75% through chemical fertilizer, T7- VC @ 2.5 t/ha + PGPR 0.2 l/plot + 50% through
chemical fertilizer, T8- VC @ 2.5 t/ha + PGPR 0.2 l/plot + 25% through chemical fertilizer, each
treatment was replicated three times in Randomized Block Design. Treatment T6 recorded highest
available NPK content i.e (374.37, 65.17, 416.38 kg ha-1) respectively. The application of
vermicompost @ 2.5 t/ha + PGPR @ 0.2 l/plot + 75% through chemical fertilizer registered
significant increase in the plant growth parameters i.e. plant height, polar and equatorial diameter and
ascorbic acid content. Application of the same treatment was found to significantly increase the curd
yield over 100 per cent RDF through chemical fertilizers. The soil available NPK content also
increased significantly by 30.26 per cent, 35.43 per cent, 9.08 per cent with the application of
vermicompost @ 2.5 t/ha + PGPR @ 0.2 l/plot + 75% through chemical fertilizer over initial values.
The conjoint application of bulky organic manures (VC, FYM) and chemical fertilizers may be
recommended after conducting multi-location trials for increasing the yield of broccoli and sustaining
soil health under mid-hills of Himachal Pradesh.
