Abstract
A field experiment entitled “Effect of different combinations of
organic nutrient sources on growth and yield of maize (zea mays L.)
under cauvery command area” was conducted at Zonal Agriculture
Research Station, V.C. Farm Mandya, during kharif season of 2009-10
on sandy loamy soil to study the effect of different combinations of
organic nutrient sources on growth and yield of maize, soil properties,
uptake of NPK in maize and to compute B: C ratio. The treatment
consists of FYM, poultry manure, vermicompost, press mud equivalent to
FYM (N) in combination of biodigester liquid and cattle urine equivalent
to 150 kg N compared with recommended dose of FYM+NPK. The
experiment was laid out in a randomized complete block design with nine
treatments replicated thrice. significantly higher plant height (187.17cm),
number of leaves per plant (13.32), grain yield (61.84 q ha-1) and stover
yield (111.31 q ha-1) was recorded in the treatment combinations of
recommended dose of FYM 10 t ha-1 + NPK 150: 75: 40 kg ha-1 N and it
was on par with the treatment combinations of poultry manure
equivalent to FYM (N) + biodigester liquid equivalent to 150 kg N. The soil
properties viz., Bulk density , particle density, maximum water holding
capacity, pH, EC, OC, major nutrients, secondary nutrients and
micronutrients (Zn,Fe,Mn &Cu) was not differed significantly due to
different combinations of organic nutrient sources. Significantly higher
total nutrient uptake of N, P and K (194.17, 50.70 and 223.60 kg ha-1
respectively) were recorded in the treatment receiving FYM 10 t ha-1 +
NPK 150: 75: 40 kg ha-1 N. Higher B: C ratio (3.15) was recorded in the
treatment combination of poultry manure equivalent to FYM (N) +
biodigester liquid equivalent to 150 kg N followed by the treatment
combinations of FYM 10 t ha-1, recommended NPK 150: 75: 40 kg ha-1 N
(3.08).
