J.Res. ANGRAU 40(1)6-12, 2012 RESPONSE OF MAIZE (Zeamays L.) TO IRRIGATION SCHEDULING AND NITROGEN DOSES UNDER NO TILL CONDITION IN RICE FALLOWS M. MALLA REDDY, B. PADMAJA and D. VISHNU VARDHAN REDDY Regional Agricultural Research Station, Acharya N.G.Ranga Agricultural University, Warangal – 506 007 Date of Receipt : 23.12.2011 Date of Acceptance : 21.01.2012 ABSTRACT Field experiments were conducted during winter season of 2007-08 and 2008-09 in sandy clay loam soils of rice fallows at Regional Agricultural Research Station, Warangal to find out the best irrigation schedule and optimum nitrogen dose to maize crop grown under zero tillage. The experiment was laid out in split-plot design with three irrigation schedules and three nitrogen doses which was replicated thrice. It was found that irrigating maize crop at an IW/CPE ratio of 1.0 was significantly superior to 0.6 but at par with 0.8 regarding plant dry weight (g) at harvest, number of kernels/cob, kernel weight (g)/cob, kernel yield (kg ha- -1 ) and stover yield (kg ha -1 ). Higher net returns (Rs. ha -1 ) and nitrogen uptake (kg ha -1 ) were observed with the IW/CPE ratio of 1.0. Further, application of 180 kg N ha -1 was found to be optimum for getting higher yields of maize under zero tillage in rice fallows. Cultivation of maize gained momentum during rabi season especially under zero tillage in rice fallows in Andhra Pradesh. Maize yields are influenced by a number of environmental factors such as growing season, weather conditions, water availability and soil conditions. To improve and sustain the productivity of maize in rice fallows, proper irrigation schedule along with the application of optimum dose of nitrogen is imperative. Hence, the present investigation was taken up to study the influence of irrigation schedules and nitrogen doses on growth and yield of maize in rice fallows under no till condition. MATERIALS AND METHODS Field experiments were conducted during winter season of 2007-08 and 2008-09 in rice fallows under no till conditions at the Regional Agricultural Research Station, Warangal, Andhra Pradesh. The soil was sandy clay loam with a p H of 7.9 and EC of 0.25 d Sm -1 , medium in available organic carbon (0.44%) and low in available nitrogen (215 kg/ha), medium in available P 2 O 5 (24.6 kg /ha) and low in available K 2 O (273 kg/ha).The experiment was laid out in split-plot design comprising of nine treatment combinations with Irrigation schedules (3); I 1 :0.6 IW/ CPE ratio, I 2 : 0.8 IW/CPE ratio and I 3 :1.0 IW/CPE ratio as main plots and Nitrogen doses (3): N 1 :120 kg, N 2 :180 kg and N 3 :240 kg/ha as sub plots and replicated thrice. The rainy season rice was sown with puddling during first week of July and harvested during 3 rd week of November. A light irrigation was given four days before harvesting of rice. To facilitate good germination and maize was dibbled manually at a depth of 5 cm @ one seed/hill in the rice fallows on 27 th and 20 th November during 2007 and 2008, respectively. Atrazine + glyphosate @ 2.5 kg/ha and 2.5 l/ha respectively were sprayed immediately after sowing to arrest the regrowth of rice stubbles, kill the emerged weeds and control the unemerged weeds. Maize hybrid, Dekalb Super 900M was used for the study at a spacing of 60 x 20 cm. The plot size was 6.6 x 4.5 m. Phosphorus and Potassium @ 60:60 kg/ha were applied at 15 DAS as pocketing. Maize was harvested on 22 nd and 19 th March during 2007-08 and 2008-09, respectively. A rainfall of 14.9 mm was received during 2007-08 in two rainy days and no rainfall was received during 2008-09 throughout the crop growth period. A range of mean minimum temperature of 15.3 o -23.0 o C and 19.2 o -22.4 o C and mean maximum temperature of 31.0 o - 35.3 o C and 29.3 o -36.0 o C were recorded during 2007-08 and 2008- 09, respectively. Two common irrigations of 60 mm each were given, one at post sowing for emergence and second at 10 th day after sowing for crop establishment. Irrigation water was measured with water meter fixed to irrigation source taking into consideration each irrigation treatment area and depth of water (60 mm). Scheduling of irrigation was started whenever the cumulative pan evaporation (CPE) e-mail: maduri_agron@yahoo.com 6
