Abstract
A field experiment entitled “Effect of phosphorus enriched biocompost on soil
properties, growth and yield of Finger millet (Eleusine coracana G.)” was conducted
during kharif 2018 at Shri Chamundeswari Sugars Ltd., Bharathi Nagar, Maddur (Tq),
Mandya (D). The experiment was laid out in randomised complete block design with nine
treatments and three replications. The experimental results revealed that application of 100
% NPK + RP-PSB enriched biocompost @ 10 t ha-1 significantly increased the plant height
(93.42 and 118.2 cm at 60 DAT and harvest, respectively), number of tillers per plant (3.76,
3.85 at 60 DAT and harvest, respectively), number of fingers per ear head (9.17), test
weight (3.45 gm), grain yield (3752 kg ha-1) and straw yield (6386 kg ha-1). Significantly
higher amount of soil major nutrients like N (321.56 and 279.30 kg ha-1 at 60 DAT and
harvest, respectively), P2O5 (235.68 and 204.35 kg ha-1 at 60 DAT and harvest,
respectively) and K2O (426.50 and 418.12 kg ha-1 at 60 DAT and harvest, respectively)
was recorded with the application of 100 % NPK + RP-PSB enriched biocompost @ 10 t
ha-1. Significantly higher grain and straw uptake of major nutrients like N (44.28 kg ha-1
and 47.25 kg ha-1 respectively), P (15.38 kg ha-1 and 19.16 kg ha-1 respectively) and K
(19.51 kg ha-1 and 52.36 kg ha-1 respectively) was recorded with the application of 100 %
NPK + RP-PSB enriched biocompost @ 10 t ha-1. The economics of crop production also
indicated the benefit of enrichment of biocompost and hence it may be followed to enhance
crop productivity in farmer's field.
