Abstract
A field experiment entitled “Effect of organic nutrient source on growth,
productivity and quality of chilli hybrids in dry zone of Karnataka” conducted in farmers
field at Talaku Village, Challakere Taluk, Chitradurga District (Karnataka) during kharif
season of 2013-14 & 2014-15 and pot experiment on evaluation of locally available
plants biomass as an organic micronutrient source on growth and productivity of chilli
during Summer 2014. There were 12 treatment combinations comprising three chilli
hybrids viz., KBCH-1, Arka Meghana and Devanur Deluxe and four organic nutrient
sources laidout in randomized complete block design under factorial concept. Among the
organic nutrient sources, application of vermicompost, silkworm waste and goat manure
(75 kg N equivalent ha-1 at 1:1:1 as basal) + EBDLM (75 kg N equivalent ha-1 as top
dressing) + 3 sprays of panchagavya (3 %) at 25, 50 and 75 days after transplanting
(DAT) recorded significantly higher dry chilli yield (2940 kg ha-1) which may be
attributed to significantly more number of fruits (plant-1), 100-fruit weight (g), fruit
length (cm), total dry matter production (g plant-1), leaf area (cm2 plant-1), number of
branches (plant-1) and plant height (cm) which was on par with recommended chilli
cultivation (150, 75 and 75 kg N, P2O5 and K2O ha-1) practices (2935 kg ha-1). The
quality parameters viz., ascorbic acid (mg 100 g-1), capsaicin content (%), per cent
oleoresin, were superior with lower per cent of discoloured fruit and discoloured fruit
yield (kg ha-1) with the application of vermicompost, silkworm waste and goat manure
(75 kg N equivalent ha-1 as basal dose at 1:1:1) + EBDLM (75 kg N equivalent ha-1 as top
dressing) + panchagavya (3 %) at 25, 50 and 75 DAT as compared to recommended chilli
cultivation practices (150, 75 and 75 kg N, P2O5 and K2O ha-1). Among chilli hybrids
significantly higher dry chilli yield was obtained with KBCH-1 (3020 kg ha-1) followed
by Arka Meghana (2845 kg ha-1) and Devanur Deluxe (2551 kg ha-1). The higher dry fruit
yield is attributed to more number of fruits per plant. Significantly higher ascorbic acid
(mg 100 g-1), capsaicin content (%), per cent oleoresin, lower per cent of discoloured fruit
and discoloured fruit yield (kg ha-1) were observed in KBCH-1 as compared to Arka
Meghana and Devanur Deluxe. Higher gross returns, net returns and B:C ratio were
registered (` 2,99,338 ha-1, ` 2,15,994 ha-1 and 3.59, respectively) in chilli hybrid
KBCH-1 raised on vermicompost, silkworm waste and goat manure (75 kg N equivalent
ha-1 as basal at 1:1:1) + EBDLM (75 kg N equivalent ha-1 as top dressing) + 3 sprays of
panchagavya (3 %) at 25, 50 and 75 DAT. The pot experiment results indicated that
application of Hyptis suaveolens biodigested liquid manure at 150 kg N equivalent ha-1
recorded higher dry fruit yield (kg ha-1), superior quality of fruits and higher
concentration and uptake of micronutrients as compared to the rest of the treatments
including application of recommended dose of fertilizer (150, 75 and 75 kg N, P2O5 and
K2O ha-1).
