Abstract
The present experiment entitled “Performance of field pea (Pisum sativum L.) to bio-fertilizers
in combination with chemical fertilizers” was conducted at Research Area, Pulses Section, CCS
Haryana Agricultural University, Hisar, during Rabi 2013-14 with the objective to study the combined
effect of bio-fertilizers and chemical fertilizers on growth, yield attributes and yield of field pea and to
work out the economics of various treatments. The experiment was conducted in randomized block
design with nine treatments viz., Control, seed inoculation with Rhizobium, Rhizobium + PSB,
Rhizobium + PSB + PGPR, Recommended dose of fertilizers (RDF), RDF + Rhizobium, RDF +
Rhizobium + PSB, RDF + Rhizobium + PSB + PGPR, RDF + ZnSO

. Growth parameters
i.e. plant height (cm), number of branches plant

, dry matter accumulation (g plant

) and yield
attributing character viz., number of pods plant
-1
, number of grains pod-1
, grain and biological yield (kg
ha
-1
) were significantly superior in RDF + Rhizobium + PSB + PGPR treatment over control. The
treatments receiving combined inoculation of bioinoculants (Rhizobium + PSB + PGPR) along with
RDF exhibited significantly higher N and P content and their uptake both in grain and straw over
recommended dose of fertilizers. The application of various treatments did not produce any significant
effect on K and Zn content in grain and straw. The values of K uptake in grain was significantly higher
in RDF + Rhizobium + PSB + PGPR treatment over RDF, though different treatments failed to
influence K uptake by straw. The Zn content and uptake in grain and straw also followed the trend of K
uptake in grain and straw. The significantly highest protein yield was recorded with the combined
application of RDF + Rhizobium + PSB + PGPR over rest of treatments. Significant lowest protein
yield was recorded in absolute control. Highest B:C (2.0) was observed in RDF + Rhizobium + PSB +
PGPR treatment ,while it was lowest in control (1.2).
