ABSTRACT
Field experiment conducted to study the feasibility of introducing drip irrigation and fertigation in sweet corn. The experiment was laid out in spilt plot design. The main plot treatments comprised of four irrigation levels. While in the sub plot treatments there were five fertigation levels. Thus, there were in 20-treatment combinations, replicated 3 times. Studies regarding the initial soil fertility status indicated that it was moderately high in available nitrogen (445.53 kg/ha) and phosphorus (25.54 kg/ha) and very high in available potassium (424.10 kg/ha) with high content of organic matter (1.98%).The comparison between the various irrigation levels significantly superior plant height, number of leaves, dry matter production and green cob yield (17.70 t ha-1) was obtain at irrigation level 1.0 x P.E. Among the fertigation levels, 100 percent RDF through drip recorded significantly more plant height, number of leaves, dry matter production and higher green cob yield of 18.06 t ha-1 and was on par with 75 percent RDF through drip.
