Abstract
Field experiments were conducted during kharif, 2016 and summer, 2017 at
organic farming research and development block, UAS, Bengaluru to study the effect of
Organic Nutrient Management in Okra [Abelmoschus esculentus (L.) Moench] under
Factorial Randomised Complete Block Design with 12 treatments replicated thrice. The
first experiment consisted of three factors viz., FYM (100, 150 and 200 % N equivalents
through FYM), jeevamrutha (0 and 2000 L ha-1
) and panchagavya (0 and 5 %) levels.
Application of 200 per cent N equivalent through FYM recorded significantly higher fruit
yield (9.59 and 11.31 t ha-1
) as compared to 100 per cent N equivalent through FYM
(7.38 and 8.52 t ha-1
). Soil application of jeevamrutha (2000 L ha-1
) recorded significantly
higher fruit yield (9.56 and 11.11 t ha-1
) as compared to without application of
jeevamrutha (7.64 and 9.07 t ha-1
) and foliar spray of panchagavya (5 %) recorded
significantly higher fruit yield (9.15 and 10.58 t ha-1
) as compared to without
panchagavya (8.05 and 9.60 t ha-1
) application during both the years, respectively.
Interaction of these treatments did not differ significantly. The second experiment was
laid out in Randomised Completely Block Design. There were twelve treatments
consisted with different proportions of organic manures viz., compost, vermicompost and
poultry manure and were replicated thrice. Among the different proportions of organic
manure treatments, T12 [T5 (C:VC:PM-50:25:25 %) + application of jeevamrutha at 20,
40, 60 and 80 DAS] recorded significantly higher fruit yield (7.41 and 8.98 t ha-1
) as
compared to rest of treatments. Whereas, application of 100 per cent N equivalent
through compost alone (T1) recorded lower fruit yield (T1-5.43 and 6.37 t ha-1
) during
kharif, 2016 and summer, 2017, respectively.
