Abstract

In order to study the effect of mixed and sole cropping of vetch (Vicia narbonensis L.) with triticale (X. triticosecale Wittmack) on their qualitative and quantitative traits, this experiment in was conducted during 2013-14 cropping year with seven levels of seed contribution of vetch:triticale (100:0 or sole cropping of vetch, 100:30, 100:40, 100:50, 100:60, 100:70 and 0: 100 or sole cropping of triticale) in dry land conditions of Khorramabad, Iran in the form of randomized complete block design (RCBD) with four replications at the research farm of College of Agriculture, Lorestan University. results showed that proportion of complementary components had significant effect on hay.The highest leaf dry weight was related to sole cropping of triticale and vetch (1331 and 1227 kg ha-1), respectively. Also, the highest stem dry weight in triticale and vetch obtained from combination of 100:70 and 100:60 (2798 and 1952 kg ha-1), respectively. The maximum of total forage yield in triticale and vetch obtained from combination of 100:70 and 100:60 (5445 and 5208 kg ha-1), respectively. The highest protein in triticale and vetch obtained from combination of 100:30 and 100:70, respectively. Also, the highest NDF in triticale and vetch obtained from combination of 100:70. Thus, it was showed that addition of proportion of triticale is effective on quality and quantity of production. Therefore, increase in complementary components of both plants led to reduce of digestibility and increase of NDF. LER in seed ratio of 60:100 was equal to 1.60 and competition ratio was equal to both plants (vetch and triticale) except in 30:100 treatment.
