Abstract
An experiment was conducted to assess the
influence of spacing, fertilizer levels and PGPR on yield and primary nutrients
accumulation in different parts of bhang or industrial hemp and on chemical
properties of soil. The experiment was laid out in Factorial Randomized
Complete Block Design, spacing and fertilizers levels with or without PGPR were
the factors. The results revealed, plants spaced at 15 cm × 10 cm registered
significant yield of leaves, stems and roots (7.84, 9.80 and 4.20 t ha-1
respectively). The uptake of nitrogen and potassium (450.32 and 159.13 kg ha-1
respectively) was highest in this spacing, while, the phosphorous uptake
(75.74 kg ha-1) was maximum in 10cm × 5cm spacing. Among nutrition,
125 percent RDF plus PGPR recorded a significant yield of stem and seed, also,
this treatment resulted in maximum uptake of nitrogen and phosphorus (440.33
and 72.58 kg ha-1 respectively) by the plants. It can be inferred
that spacing of 15 cm × 10 cm and application of 10 tonnes FYM with 250:125:250
kg N, P2O5, K2O ha-1 (125% RDF)
plus PGPR consortia (Azospirillum brasilense, Pseudomonas fluorescens
and Bacillus megaterium @ 5kg each) was found to be optimum to produce
higher yields. The effect of Cannabis sativa on soil reclamation of
saline-alkali soil is very good due to yield of biomass per unit area and
practiced in district of Hardoi, Bhadohi, Sultanpur, Pratapgarh, Amethi,
Raebareily, Deoria and Kushinagar.
