Effects of Manure and Different Intercropping Patterns on Quantitative and Qualitative Yield of Roselle (Hibiscus Sabdariffa) and Cowpea (Phasaeolous vulgaris)

In order to study the effects of manure and different intercropping patterns on quantitative and qualitative yield of roselle and cowpea, an experiment was conducted as split plot based on a randomized complete block design with three replications at the Agricultural Research Center of Zabol University in 2013. The treetments included 0, 20 and 30 t.ha-1 manure to main plots and different intercropping patterns (sole roselle, sole cowpea, %75 roselle + 25% cowpea, %50 roselle + %50 cowpea, and %25 roselle + %75 cowpea) in sub plots. Results revealed that in roselle the most plant height, number of fruits per plant, economic yield, biological yield and in cowpea the maximum number of pod per plant, economical yield, biologinal yield and percent seed protein of sole cropping along with application of 30 t.ha-1 manure were obtained. The highest amount anthocyanins and carbohydrates sour tea were obtained from the application of 30 t.ha-1 of manure and intercropping % 25 hibiscus + % 75 cowpea. The highest harvest index in roselle of %75 roselle + %25 cowpea and in cowpea of pure cultures along with application of 30 t.ha-1 manure were obtained.
