ABSTRACT
The present investigation “Studies on integrated nutrient management on productivity and soil
properties under pea-capsicum-radish cropping sequence” was carried out at the Experimental Farm,
Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni Solan, (HP) to
evolve INPS system for higher productivity and soil health. The experiment was laid out in RCBD with 03
replicates comprising 13 integrated combinations of inorganic and organics including Bio-fertilizers/PGPR viz.
T1: RPF= (RDF (NPK) + FYM), T2: 90 % RDF + 10 % EC + FYM + Bio-fertilizer/PGPR T3: 80 % RDF + 10
% EC + FYM + Bio-fertilizer/PGPR, T4: 70 % RDF + 10 % EC + FYM + Bio-fertilizer/PGPR, T5: 60 % RDF
+ 10 % EC + FYM + Bio-fertilizer/PGPR , T6: 90 % RDF + 10 % SMC + FYM + Bio-fertilizer/PGPR, T7: 80
% RDF + 10 % SMC + FYM + Bio-fertilizer/PGPR, T8: 70 % RDF + 10 % SMC + FYM + Biofertilizer/
PGPR, T9: 60 % RDF + 10 % SMC + FYM + Bio-fertilizer/PGPR, T10: 90 % RDF + FYM + Biofertilizer/
PGPR, T11: 80 % RDF + FYM + Bio-fertilizer/PGPR, T12: 70 % RDF + FYM + Bio-fertilizer/PGPR
and T13: 60 % RDF + FYM + Bio-fertilizer/PGPR. The reduced RDF was supplemented through organic
manures (EC, SMC) on N eq. basis. Seeds of pea cultivar Punjab- 89 were sown at spacing of 60 x 7.5cm, while
capsicum cv. Solan Bharpur was spaced at 60 x 45 cm. Similarly, radish cv. Japanese White was sown 30 x 7.5
cm apart. INM modules significantly influenced yield and plant growth attributes of all the three crops grown in
a sequence over two years i.e. 2014-15 and 2015-16. In pea, the conjoint use of 90 % of inorganic RDF(NPK) +
10 % of RDF through SMC to the bio-fertilized treated seed and soil along with basal application of
recommended FYM (T6) harvested pods; maximum in number (29.62), size (10.29 x 1.26 cm), weight (6.63 g),
shelling (41.72 %) and pod yield (179.35 q/ha) as compared to RPF (T1) which recorded values of 24.37, (9.99 x
1.21 cm) , 5.85 g, 36.83 % and 157.17 q/ha , respectively. Similarly, in capsicum, the same module ( T6) relying
on best performance of major yielding components viz. fruit size (6.06 x 4.96 cm), fruit weight (49.59 g) and
number of fruits per plant (28.63) and consequently the highest yield (351.55 q/ha), excelled all the modules
including RPF(282.31q/ha). T6 module also measured maximum root size (18.80 x 2.86 cm), root weight
(130.42 g) and consequently increased yield of 11.44 percent in radish over RPF (296.31q/ha). For quality
traits; protein in pea was more pronounced in high inorganic supportive modules whereas; TSS, ascorbic acid in
capsicum as well as radish and fibre, dry matter content and total sugar in radish were high through high
organics support. Overall, this module (T6), earned highest annual net return of Rs. 12.71 lacs per hectare with a
B: C ratio of 2.80, besides enhancing soil health as evident through the increased post harvest availability of N,
P and K by 13.95, 26.80 and 22.22 %, over their initial (pre-experimental) content in the soil. Therefore, it can
be concluded that above module i.e. T6 (90 % RDF + 10 % SMC + FYM + Bio-fertilizer) along with basal
application of recommended FYM resulted in saving of 10 % of fertilizers (NPK), better growth, improving
yield, net returns and also enhanced soil health in mid hill condition of Himachal Pradesh.
