Effect of nitrogen, salinity and water regimes on crop growth and yield of Aloe in semi-arid regions

摘要

The experiment was conducted during 2011-13 to study the effect of salinity levels, water regimes and nitrogen on crop growth, yield and economics of aloe (Aloe barbadensis Mill.). The results revealed that the crop growth parameters (plant height and plant spread), yield attributes (number of harvested leaf, weight of leaf, leaf length, width and thickness of leaf), and number of suckers were significantly affected with individual treatment. The application of higher doses of N increase the yield of aloe leaves significantly. The leaves yield was significantly reduced in higher salinity levels (9dS m~(-1)) but no significant difference in ECiw 3,6 and best available water treatments. There was a significant increase in yield of leaves ha~(-1) (36.8%)and number of suckers arises (31.1%) due to irrigation scheduled at 1W: CPE ratio 0.2 over 1W: CPE ratio 0.1 in pooled basis, respectively.
