Abstract
Turmeric (Curcuma longa L.) is an important, sacred and ancient
spice of India. The root, rich in diverse phytochemicals and minerals,
exhibits numerous pharmacological properties including
anti-inflammatory, antioxidant, anti-cancer and neuro- protective effects,
primarily due to curcumin. India is the major producer and exporter of
turmeric. India is also the largest consumer of turmeric in the world
accounting for nearly 90% of total production. Sakleshpur falls under hilly
zone of agro climatic zone-IX of Karnataka. Traditionally plantation crops like
coffee, cardamom and black pepper are predominantly grown and rice is
cultivated in the plain region. Due to escalating cost in paddy cultivation,
farmers are alternatively attempting ginger cultivation in this area. Since
ginger experiences high disease load and high cost in production alternatively
turmeric is attempted. Turmeric is hardy with majority of biotic and abiotic
stress in comparison to ginger. IISR has released various turmeric cultivars
which are widely adopted across different agroclimatic zones. Hence an
observational study was planned to evaluate various released and local
cultivars and their suitability under Sakleshpur condition. The study reported here was initiated in April 2022 and was repeated
for a period of two seasons (2022-2023. 2023-2024). The experiment was
conducted under irrigated condition. The soil of experimental plot was sandy
loam in texture, pH 5.9 organic carbon content 1.3%, phosphorus 18 kg/ha,
potassium 338 kg/ha. The trail was laid out in Randomized complete block design (RCBD) with four
replications and five turmeric cultivars. IISR-Pratibha, IISR-Pragathi, Alleppey Supreme, Pitambar and Mydukur local. Turmeric
cultivar IISR Prathibha and Mydukur local recorded significantly higher plant
height of (128.4 & 122.6 cm) and number of tillers/clump (6.4 & 5.8) at150
days after sowing, while IISR Pragathi recorded lower plant height (72.4 cm)
and number of tillers/clump (2.3). Significantly higher fresh mother (78.4g),
primary (278.9 g) and secondary (42.0g) rhizome weight was recorded in turmeric
cultivar IISR-Prathibha. Similarly, per plant fresh rhizome yield was also
significant higher in IISR-Prathibha (399.3g/plant) and Mydukur local (373.0
g/plant). On the contrary IISR Pragathi performance is absolutely poor from
both growth and yield attributes. Similarly, the fresh rhizome yield per
hectare was recorded maximum in IISR Prathibha (27.95 t/ha) and Mydukur Local
(26.11 t/ha). Similarly, lowest fresh weight of rhizome was observed in IISR
Pragathi (6.69 t/ha). Significantly higher dry recovery was observed in
turmeric cultivar Mydukur local (24.02%). This ultimately assisted the Mydukur
local turmeric cultivar to attain significantly higher dry rhizome (6.27 t/ha)
in spite of higher fresh rhizome yield observed in IISR Prathibha. Hence higher
net return and BC ratio was observed for Mydukur local turmeric cultivar (Rs 229013/- & 2.09).
