ABSTRACT
The present investigation entitled “Effect of bamboo species and integrated nutrient
management on productivity of ginger crop” was carried out at the experimental farm of the
Department of Silviculture and Agroforestry, Dr. Y.S. Parmar University of Horticuture and
Forestry, Nauni, Solan 173230 (H.P.) during 2012-2013. The experiment was laid out in split plot
design comprising of two bamboo species viz., Dendrocalamus asper and D.hamiltonii and open
field condition, under which ginger crop was grown with five integrated fertilizer doses viz., T1
(RDF), T2 (FYM on N equivalent ratio + PGPR), T3 (VC on N equivalent ratio + PGPR), T4 (75%
RDF + PGPR) and T5 (50% FYM + 50%VC + PGPR). Treatment T2 showed best results in
growth and yield parameters of ginger crop viz., rhizome sprouting(%), tillers per plant, rhizome
length (cm) and yield (q ha-1). D. asper displayed better results for growth and yield traits of
ginger when compared to D. hamiltonii and open field conditions. Various soil physico-chemical
parameters viz., pH, OC, SOC density, N, P, K and soil moisture (%) showed maximum value in
treatment T2 (FYM on N equivalent ratio + PGPR) under D. asper. However, exchangeable Ca
and Mg was reported maximum in treatment, where, VC was applied on N equivalent ratio with
PGPR. Further, soil moisture content (%) reported higher value under D. asper. PAR recorded
during the investigation period, reduced by 60% under the bamboo canopy. Based on the findings
of this study, it can be concluded that ginger can perform better under bamboo based agroforestry
system than sole crop system and application of FYM on N equivalent ratio plus PGPR can
enhance growth and yield traits of ginger significantly over control
