Abstract
ABSTRACT
The present investigation entitled “Manurial studies on yield and quality of turmeric
(Curcuma longa L)” was laid out in a RCBD with three replications in plot size of 3×1 m and
spacing 30×20 cm at Vegetable Research Farm and Quality Analysis Laboratory of the
Department of Vegetable Science, Dr YSPUHF, Nauni, Solan (HP) during Kharif 2018. The
treatments comprised of five manurial practices (M) viz M1: Manure (200 q/ha FYM), M2:
Seed treatment with Beejamrit + spray of Jeevamrit, M3: Manure (200 q/ha FYM) +
Beejamrit + Jeevamrit, M4: RDF (200 q/ha FYM + 30 kg N + 30 kg P2O5 + 60 kg K2O per
ha) and M5: Absolute control; and three stages of harvesting (S) viz S1: 180 DAP, S2: 210
DAP and S3: 240 DAP. The observations were recorded on crop parameters like plant height
(cm), tiller girth (cm), number of tiller per plant, number of leaves per plant, leaf length and
width (cm), leaf area index, yield per plant (g) and projected yield per hectare (q); rhizome
length and breadth (cm), number of primary and secondary rhizomes, specific gravity (g/cc),
dry rhizome recovery (%), essential oil (%), oleoresin content (%), total curcuminoid content
(%), and soil parameters like soil pH, electrical conductivity, organic carbon, available N, P
and K (kg/ha). The analysis of variance showed significant differences among the treatment
combinations for majority of characters studied. From the present investigation it can be
concluded that turmeric variety Palam Lalima gave the highest fresh rhizome yield of
improved quality i.e 346.53 q/ha at 240 DAP by the application of FYM (200 q/ha) + seed
treatment with Beejamrit + spray of Jeevamrit having a net return of Rs 7,60,456 with B : C
ratio 2.72; whereas, yield of 289.52 q/ha was obtained by the application of seed treatment
with Beejamrit + spray of Jeevamrit having a net return of Rs 6,47,169 with maximum B : C
ratio 2.92.
