摘要

Two field experiments during 1996-98 at Bangalore, India studied the effect of soil moisture regimes (0.3, 0.6 and 0.9 IW:CPE rations) irrigation water:cumulative pan evaporation (IW:CPE) ratios and three levels of nitrogen application (0, 100 and 200 kg ha~(-1)). Another experiment investigated three irrigation levels (0.3, 0.6 and 0.9 IW:CPE ratios), two levels of nitrogen application (100 and 200 kg ha~(-1)) and organic mulch (0 and 5 t ha~(-1)) on oil content, herbage, oil yield and quality of geranium grown on alfisols. Soil moisture maintained at 0.6-0.9 IW:CPE ratios significantly increased both the herbage and oil yields of geranium. Application of 200 kg N ha~(-1) gave maximum herbage and oil yield compared with those obtained from 0 and 100 kg N ha~(-1). Organic mulch increased the oil yield of geranium. The concentration and quality of essential oil were not influenced either by soil moisture regime, N rates or organic mulch.
