National level e-symposium on “Agroforestry system for augmenting livestock
productivity and empowering resource poor rural farmers”
and soil carbon stocks up to 1 m depth was estimated (Joy et al., 2019). All parameters were scaled to hectare
basis. The data were subjected to statistical analysis by analysis of variance (ANOVA) using general linear
model procedure in SPSS version 21.0, to ascertain the significance of various parameters.
Results and discussion
A significant enhancement in productivity and carbon capture has been noticed due to calliandra
intercropping in coconut gardens. Calliandra stands yielded maximum dry forage and crude protein (35.16
and 6.65 Mg ha coconut garden over three year period) at the highest tree density of 27,777 plants ha and

at 12 weeks harvest interval, when compared to other management options. In addition, this intercropping
system has captured 90 Mg ha additional carbon during the three-year period in the plant biomass and in soil

up to 1m depth (199.19 Mg ha ), when compared to coconut monoculture systems (108.73 Mg ha ).

Hence the study concludes that, calliandra is a promising fodder tree for hedgerow intercropping in
coconut gardens of humid tropical Kerala to enhance quality forage production. Adoption of ideal stand
management techniques can substantially enhance the forage and protein yields thereby providing direct
benefit to the farmers. In addition, the intercropping practices can almost double the carbon fixation rates than
in coconut monoculture systems, and provides environmental services via climate change mitigation.

Introduction
Morus indica, Calliandra calothyrsus, Sesbania grandiflora , Gliricidia sepium, and Moringa oleifera
are promising fodder trees by virtue of their nutritive foliage, fast growing nature, ability to withstand heavy
pruning, good coppicing ability and higher biomass production (Raj et al., 2016; Joy, 2017; Sagaran, 2017).
Maintaining these fodder trees as hedges also regulate the possible competition between the component crops
in homesteads and facilitate easy harvesting of fodder. Information exists on the performance of tree species
