Abstract

Study of agronomic characteristics and advantage indices in intercropping of additive series of Chickpea (Cicer arietinum L.) and Black Cumin (Nigella sativa L.)
Abstract
In order to evaluate quantitive and qualitive yield of Chickpea (Cicer arietinum L.) and Black Cumin (Nigella sativa L.) in intercropping of additive series, a field experiment was arranged in a randomized complete block design with three replications in West Azerbaijan province- city Nagadeh, Iran during growing reason of 2012-2013. Treatments included 100% Black Cumin + 10% Chickpea, 100% Black Cumin + 20% Chickpea, 100% Black Cumin + 30% Chickpea, 100% Black Cumin + 40% Chickpea and 100% Black Cumin + 50% Chickpea and sole cropping of Chickpea and Black Cumin. Different Planting Ratio had significant effect on studied traits of Chickpea and Black Cumin (exception Essential oil yield of Black Cumin). Yield and components yield in monoculture of each crop was more than other treatments. The highest grain yield and biological yield of chickpea were achieved in monoculture with 1105 and 14479 kg.ha-1, respectively. The results showed that the maximum seed yield and biological yield of Black Cumin were obtained at monoculture with 750 and 2310 kg.ha-1, respectively. The highest of percentage of grain protein (23%) and essential oil percentage (1.47%) were related to treatment 100% Black Cumin + 50% Chickpea, respectively. Based on this results, the highest land equivalent ratio (LER=1.74), actual yield loss (AYL=6.45) and intercropping advantage (IA=1.70) were obtained by treatment 100% Black Cumin + 10% Chickpea, respectively. Therefore, it seems that treatment 100% Black Cumin + 10% Chickpea is remarkably effective to increase the economic income and land use efficiency.
