Abstract
Field experiment was conducted during summer season
of 1982 at the College Farm of Gujarat Agricultural
University, Naysari on 'heavy clayey' soil to study the
effect of nitrogen, phosphorus and potash on the yield
and yield attributing characters of hybrid maize (var.
Ganga Safed-2).
Eighteen treatment combinations consisting of three
levels of nitrogen viz., 60, 120 and 180 kg/ha, three
levels of phosphorus viz., 0, 30 and 60 kg/ha and two
levels of potash viz., 0 and 60 kg/ha were tried in
randomized block design with four replications.
Application of 120 kg N/ha significantly increased
the plant height, length and girth of cob, number of
grains per cob and grain yield per cob. This reflected
in marked effect on increasing grain yield of maize.
Application of 60 kg P205/ha increased significantly
the plant height, length of cob, number of grains
per cob and grain yield per cob which resulted into
higher stover anct grain yield.
Potash application j 60 kg K20/ha significantly
increased the number of grains per cob, grain yield
per cob and stover as well as grain yield.
From the economic point of view the nighest net
return of Rs. 3910/ha was obtained. by application of
180 kg N + 6U kg p
