Abstract
ABSTRACT
The present investigation entitled "Effect of different biofertilizers and planting
densities on the growth and yield of Spilanthes acmella Murr. under Morus based
agroforestry system" was carried out at the experimental field of Department of Silviculture
and Agroforestry, Dr Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan,
Himachal Pradesh during 2015. The study was undertaken with the objectives (a) to study the
effect of different types of biofertilizers on the growth and yield of Spilanthes acmella and
(b) to study the growth of Spilanthes acmella under different planting densities. The
experiment was laid out in a split plot design comprising of Morus alba as tree component
planted at a spacing of 9 m x 3 m and open field condition, under which akarkara plants
treated with 5 different biofertilizer combinations viz. T1 (Plant growth promoting
rhizobacteria + FYM), T2 (Azotobacter + Phosphate solubelizing bacteria + FYM), T3
(Azotobacter + Vesicular arbuscular mycorrhiza + FYM), T4 (Azospirillum + Phosphate
solubelizing bacteria + FYM), T5 (Azospirillum + Vesicular arbuscular mycorrhiza + FYM )
and T6 (RDF + FYM) as control were grown. A sub-treatment of three different planting
densities S1 (30 cm x 40 cm), S2 (30 cm x 30 cm) and S3 (30 cm x 20 cm) were incorporated
for each of the biofertilizer treatments. The plot size was 2 m x 1 m. The observations were
recorded on multiple growth and yield parameters of akarkara and soil chemical properties.
All biofertilizer treatments had no significant influence on the growth and yield attributes of
akarkara. Planting condtions, however, did significantly affect all the growth and yield
attributes of akarkara where plants under sole cropping showed better results as compared to
tree associated plants. Planting density also significantly influenced the growth and yield
attributes where plants S2 and S3 performed better as compared to S1. From the present
investigation, it can be concluded that akarkara performed better under sole cropping
conditions and the biofertilizers selected for the study had no significant effect on the growth
and yield of the plant. Furthermore, standardization of planting density requires further
studies particularly for agroforestry systems.
