Study of quantitative and qualitative traits of triticale (X. triUcosecale Wittmack) and rough pea (Lathyrus sativus L.) in sole and mixed cropping in dry farming conditions of Iran

摘要

In order to study the effect of mixed and sole cropping triticale (X. triUcosecale Wittmack) with rough pea (Lathyrus sativus L.) on their qualitative and quantitative traits, this experiment in cropping year 2008-09 was conducted with five levels ofseed contribution of triticale : rough pea (100 : 0, 0 : 100, 20 : 80, 40 : 60 and 60 : 40) (in dry land conditions of khorramabad in 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 (leaf and stem). The highest leaf dry weight was related to sole cropping of triticale and rough pea (349.8 and 612.3 kg/ha), respectively. Also, stem dry weight by these two treatments (1751 and 715.1 kg/ ha). The maximum of biological yield in triticale and rough pea obtained from sole cropping of triticale and combination 40 : 60 was equal to 6492 and 2919 kg/ha, respectively. Theresults in study treatments showed that under efficacy of different seed combinations, changed dry matter (DM) and its quality, the highest total hay yield (3101 kg/ha) was related to combination 60 : 40. Thus, this treatment was higher than other treatments in quality and total LER (TLER). Therefore, this combination was found the most suitable for forage produce and exploitation of resources.
