Barley yield, yield components and nutrient content in intercropped system of walnut and barley

The aim of research was to determine the productivity of the intercropped system of walnut and winter barley and investigate how barley performed in that system in terms of yield, yield components, and nutrient content in the grain. Field trial consisted of three plots: a) control plot of monoculture barley ; b) sole walnut orchard ; c) walnut orchard with intercropped barley. Despite decreased barley yield, the LER value of 1.53 showed that intercropping had a productive advantage over monoculture systems. Also, the number of fertile spikelets, the length of spikes, the weight of 1000 grains, and the nutrients content of N, P, K, Cu, Fe, and Zn were statistically higher in barley grown in the intercropped orchard. These results suggest that walnut tree vicinity could have a positive effect on barley yield quality.
