A field
experiment was conducted at wondo genet Agriculture research center
under irrigated condition to diversify onion based farming system by
inclusion of rosemary for additional cash generation and to determine
optimum percentage of rosemary in onion-rosemary based farming system
during the two successive seasons of 2014 and 2015. The experiment
comprised of six treatments in additive series: sole onion (250000
plants ha-1), sole rosemary (83333 plants ha-1) and 4 onion-rosemary
intercropping mix- proportion: 100 onion:80 rosemary, 100 onion:60
rosemary, 100 onion:40 rosemary and 100 onion:20 rosemary, using
randomized complete block design with four replications. Analysis of
variance revealed that; intercropping of onion with different population
densities of rosemary might affect fresh and dry bulb yield; highest
bulb fresh yield and dry bulb yield were recorded at solitary cropping
than that of intercropped. Regardless of mix proportion, highest (10973
kg/ha) and lowest (7839kg/ha) value of dry bulb yield were recorded at
20% and 80% rosemary intercropped with onion, respectively. Likewise;
essential oil yield of rosemary was significantly influenced by cropping
system; highest essential oil yield was obtained in sole planted than
intercropped. In the same way, essential oil yield of rosemary was
affected by different level of intercropped treatments; highest and
lowest Essential oil yield were obtained at 80% and 20% rosemary
intercropped with onion. The highest value of Land Equivalent Ratio
(1.68) and Monitory Advantage (3956.5) were obtained when onion
intercropped with 80 % rosemary population density. Therefore, the
inclusion of onion with 80% a rosemary intercropping scheme raised yield
advantage over the single crop per unit area and year as revealed by the
highest total LER, and monetary advantage.
