| dc.description.abstract | An experiment entitled as, MA study on water movement and N availability as influenced by water application rates and N levels under pitcher irrigation for cabbage (Brassica oleracea var. Capitata, L.) in black soil (vertisols)" was conducted on black clayey soil (pH 8.1, EC 0.4 mmhoa/cm, FC 42 % and PUP 22 %) during rabi season of 1984 at Water Management Project, MPAU, Rahuri. The irrigation treatments comprised of application of water at the rate of 0.5, 1.0, 1.5 and 3.0 l/day through pitcher and irrigation scheduled at 50 cm CPE (6.0 cm depth) with three nitrogen levels (recommended dose of 60 kg/ha, 70 % and 40 % of recommended dose). Nitrogen fertilizer was applied in the form of urea through pitcher and compared with surface application. An experiment was conducted in RBD with 4 replications. Application of Water through the pitcher at the rate of 3.0 l/day was found significantly superior (38.50 t/ha) to rest of the irrigation treatments but treatment of 1.5 l/day uas on par (37.01 t/ha) with respect to cabbage yield. There uas water saving to the extent of 51.86 per cent uhen treatment of 1.5 l/day water application (CU = 202.2 mm) was compared with the control treatment of irrigation scheduled at 50 mm CPE (CU = 377.0 mm). Water use efficiency under treatment of 1.5 l/day application was 183 kg/ha-mm consecutively there was increase in the yield of 34.2 per cent uhen compared with control treatment. Yield uas significantly reduced when N fertilizer dose uas reduced to 40 per cent. The yield of recommended dose (32.90 t/ha) and 70 per cent reduction (32,32 t/ha) were significantly superior but were on par with each other. There was saving in N fertilizer to the extent of 18 kg/ha due to adoption of pitcher irrigation method for water application. Soil water movement studies showed that wetting front was moved to the extent of 60 and 80 cm for vertical and horizontal directions respectively uhen water was applied at the rate of 1.5 l/day. Unsaturated hydraulic conductivity showed exponential relation with increase in volumetric water contents. | en_US |
