ABSTRACT
The present investigations entitled “Productivity of ginger crop (Zingiber officinale Rosc.) in
response to application of mulch under bamboo based agroforestry system” was carried out at the
experimental field of Department of Silviculture & Agroforestry, Dr. Y.S. Parmar University of
Horticulture and Forestry, Nauni, Solan (H. P.) during 2019-2020. The study was undertaken with the
three objectives (a) to study the effect of bamboo species and mulch material on ginger growth and
yield behavior. (b) to study the impact of bamboo species and mulch material on soil physicochemical
characteristics. (c) to work out the cost-benefit analysis of ginger cultivation under bamboobased
agroforestry system. The experiment was laid out in randomized block design comprising of
two bamboo species viz., Dendrocalamus asper and D. balcooa and sole cropping, under which
ginger crop was grown with 7 treatments viz., T1 (Toona ciliata + FYM + RDF), T2 (Artemisia
vulgaris + FYM + RDF), T3 (Ulmus villosa + FYM + RDF), T4 (Celtis australis + FYM + RDF), T5
(Pinus roxburghii + FYM + RDF), T6 (FYM + RDF), T7 (Control). Treatment T1 showed best results
in most of the growth and yield attributes of ginger crop viz., Rhizome sprouting (%), Number of
tillers per plant, Number of rhizomes per plant, Rhizome length (cm), Rhizome fresh weight (g), Yield
(q ha-1), Oleoresin content (%). D. asper displayed better results for yield traits for ginger when
compared to D. balcooa and sole cropping. Various soil physico-chemical properties like pH, OC and
available N showed maximum value in T3 (Almus villosa + FYM +RDF). However, available P was
reported maximum value in T1 (Toona ciliata + FYM + RDF) and available K was in T4 (Celtis
australis + FYM + RDF). Further, soil moisture content (%) reported higher value under D. balcooa.
LTR (%) recorded during the investigation period, reduced by 40% under 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 Toona ciliata + FYM + RDF can
enhance growth and yield traits of ginger significantly over control. The mulch of species like Toona
ciliata, Artemisia vulgaris and Pinus roxburghii can be used for enhancing the fertility status and
returns fromginger cultivation.
