ABSTRACT

A field experiment was conducted during rabi 2007-08 cropping season The trial was laid
out in RBD with 3 replications. The treatment combinations consisted of irrigation schedules
and fertigation levels (8); irrigation scheduled at 1.0 and 0.75 Epan, fertilizer doses (100%
NPK RDF and 75% NPK RDF) and fertilizer forms (water soluble and straight fertilizers). The
grain yield was significantly higher (7.46 t/ha) in fertigation scheduled at 1.0 Epan and 100%
RDF with water soluble fertilizers (MAP, urea, KNO3) over fertigation at 1.0 Epan with 100%
RDF through conventional fertilizers (N&K fertigation and P as basal soil application). The
water productivity (kg/m3) was highest in fertigation at 1.0Epan (1.70 kg/ m3) with 100% RDF
with water soluble fertilizers (MAP, urea, KNO3 ) which was closely followed by fertigation at0.75
Epan (1.50 kg/ m3) coupled with 75% RDF with water soluble fertilizers (MAP, urea and KNO3 )
over conventional method of ridge and furrow irrigation with 100% RDF through conventional
fertilizers (0.74/ m3).
