Abstract
A field experiment was conducted at organic farming block of UAS, GKVK,
Bengaluru, during kharif 2014 to study the effect of jeevamrutha and farm yard manure
(FYM) application on growth and yield of fieldbean. The experiment was laid out in a
RCBD with three replications of two factors at different levels. The treatment
combination include three FYM levels (100%, 150% and 200% N equivalents through
FYM) and four jeevamrutha levels (0, 500, 1000 l ha-1 and 1500 l ha-1). Application of
FYM at 200 % N equivalent recorded significantly higher grain yield (1136 kg ha-1) an
increase of 16.7 % compared to FYM at 100 % N equivalent (946 kg ha-1). Similarly
application of jeevamrutha at 1500 l ha-1 recorded significantly higher grain yield (1246
kg ha-1) an increase of 35.1 % compared to without jeevamrutha application (808 kg ha-
1). These treatments also showed similar trend with respect to growth and yield
parameters and also nutrient concentration in plants (nitrogen, phosphorus and
potassium). There was significant improvement in soil nutrient status (available N, P2O5
and K2O) and soil microbial load (bacteria, fungi, actinomycetes, phosphate solubilizer
and N-fixer) as FYM and jeevamrutha levels increases after harvest of the crop. Higher
B:C ratio (1.99) was realized with FYM at 200 % N equivalent + jeevamrutha at 1500 L
ha-1 followed by 150 % N equivalent through FYM + jeevamrutha at 1500 l ha-1 (1.91).
