Description Field experiments were conducted during kharif and rabi seasons of 2011
and kharif and summer seasons of 2012 at ZARS, GKVK, UAS, Bengaluru for
development of liquid organic manures and their evaluation for organic
production of chilli and onion. There were thirteen treatments replicated thrice
in Randomized Complete Block Design. Application of EBDLM at 125 kg N
eq./ha + three sprays of panchagavya (3%) recorded significantly higher dry
chilli yield (897 kg/ha) as evidenced by higher total dry mater accumulation
(105.7 g/plant) and taller plants (87.0 cm) along with number of fruits/plant
(39.0) and 100-fruits weight (135.1 g). Significantly higher ascorbic acid,
capsaicin, oleoresin content and total extractable colour (137.3 mg/100 g, 0.64,
15.4 %, 280.8 ASTA units, respectively), higher nitrogen, phosphorus and
potassium uptake (76.9, 14.2 and 84.7 kg/ha, respectively) and also higher net
returns and B:C ratio (Rs. 96,281/ha and 2.74, respectively) recorded with the
application of EBDLM at 125 kg N eq./ha + three sprays of panchagavya (3%).
Bulb yield of onion was significantly higher (42.8 t/ha) with the
application of EBDLM at 100 kg N eq./ha + three sprays of panchagavya (3%)
as evidenced by higher bulb diameter (6.02 cm), bulb length (5.36 cm). This was
linked to taller plants and higher total dry matter production (42.3 cm and 7.59
g, respectively). Application of EBDLM at 100 kg N eq./ha + three sprays of
panchagavya (3%) recorded higher TSS, total sugar and ascorbic acid (14.4,
13.03%, and 26.1 mg/100 g, respectively) in onion bulbs. Significantly higher
uptake of nitrogen, phosphorus, potassium and sulphur (83.1, 14.8, 62.6 and
16.3 kg/ha, respectively), higher net returns and B:C ratio (Rs. 3,61,557/ha
and 4.27, respectively) were recorded with the application of EBDLM at 100 kg
N eq./ha + three sprays of panchagavya (3%).
