Pradeep Kumar, S.S. Sengar<strong>in</strong>volves application <strong>of</strong> fertilizer with drip irrigation system at a slow and controlled rateto the root zone. Therefore, an attempt was made to study the effect <strong>of</strong> irrigation methods,levels and fertigation on cabbage.MATERIAL AND METHODSAn <strong>in</strong>vestigation was carried out to exam<strong>in</strong>e the effect <strong>of</strong> irrigation and fertigationlevels on growth and yield <strong>of</strong> cabbage. The treatments comprised <strong>of</strong> five irrigation levelsviz., furrow irrigation at 1.2 IW/CPE (control), drip irrigation at 100, 80, 60 and 40 percent PE as ma<strong>in</strong> plots and five nitrogen levels viz., 50, 75, 100, 125 and 150 per cent <strong>of</strong>recommended dose <strong>of</strong> nitrogen as sub plots. The experiment was laid out <strong>in</strong> split-plotdesign with three replications. Meteorological approach based on the ratio betweenirrigation water (IW) and cumulative pan evaporation (CPE) was adopted for level <strong>of</strong>irrigation <strong>in</strong> one treatment (1.2 IW/CPE). Whereas, other four treatments were irrigatedthrough drip on the basis <strong>of</strong> daily pan evaporation (mm day -1 ). The depth <strong>of</strong> irrigationwas ma<strong>in</strong>ta<strong>in</strong>ed as 4 cm at each irrigation. Nitrogen was applied through drip irrigationsystem (fertigation). Weight quantity <strong>of</strong> urea as per sch<strong>edu</strong>led was added <strong>in</strong> water andthen <strong>in</strong>jected through the lateral l<strong>in</strong>es as per treatments.RESULTS AND DISCUSSIONOn perusal <strong>of</strong> the data <strong>in</strong> table 1 revealed that, drip irrigation at 100 per cent PErecorded significantly highest plant height (19.39 cm), number <strong>of</strong> leaves (13.08) perplant, diameter <strong>of</strong> head (13.11 cm), gross weight <strong>of</strong> head (1.66 kg), net weight <strong>of</strong> head(1.20 kg) and cabbage head yield (30.60 ton/ha) Mitigat<strong>in</strong>g the water deficit to the level<strong>of</strong> pan evaporation demand through drip irrigation improved the availability <strong>of</strong> appliedwater through the establishment <strong>of</strong> relatively moist condition <strong>in</strong> the root zone and also<strong>in</strong>crease the availability <strong>of</strong> nutrients throughout the crop growth period. Such an effectwas responsible for significant improvement <strong>in</strong> growth parameters, yield attributes andyield <strong>of</strong> cabbage (Sharanappa and Gowda, 1995; Deolankar et al., 2004 andL<strong>in</strong>gaiyah et al., 2005).Fertigation with 150 per cent <strong>of</strong> recommended dose <strong>of</strong> nitrogen result<strong>in</strong>g <strong>in</strong> thehigher yield <strong>of</strong> cabbage head (29.71 ton/ha) over other nitrogen levels. This <strong>in</strong>crease <strong>in</strong>yield might be attributed to higher plant height (19.55 cm), gross weight (1.63 kg), netweight (1.25 kg).Higher yield and yield attributes <strong>of</strong> cabbage <strong>in</strong> 150 per cent <strong>of</strong> recommended dose<strong>of</strong> nitrogen may be due to complete solubility, mobilization and availability <strong>of</strong> nutrients atregular <strong>in</strong>terval <strong>in</strong> required quantity due to split application (S<strong>in</strong>gh et al., 2004; Mal etal., 2005 and Rubeiz et al., 1989).97
