Effects of Mixture Ratio and Row Spacing in Hungarian Vetch (Vicia pannonica Crantz.) and Annual Ryegrass (Lolium multiflorum Lam.) Intercropping Sys

Abstract

According to the mean of 2 years, the different mixture ratios and row spacings had a statistically significant effect on all of the properties. At the end of the research, among the different mixture ratios and row spacing interactions, the highest green herbage yield (33.4 t ha -1 ), hay yield (7.5 t ha -1 ), lowest neutral detergent fiber (52.2%), and crude ash (7.8%) rates were obtained from the 60%HV+40%AR mixture and 30-cm row spacing interaction. The highest crude protein (CP) rate (17%), CP yield (1156 kg ha -1 ) and ADF (39.5%) ratios were obtained from the 80%HV+20%AR mixture and 30-cm row spacing interaction. The highest RFV value (107) was obtained from the 80%HV+20%AR mixture and 20-cm row spacing interaction. These results show that increasing the HV ratio in the mixture has positive effects on the yield and quality, whereas raising the row spacing has adverse effects on the forage values. Therefore, 80%HV+20%AR or 60%HV+40%AR with a 30-cm row spacing interaction can be suggested for forage production in an HV and AR intercropping system.

EFFECTS OF DIFFERENT MIXTURE RATIOS AND HARVEST PERIODS ON GRASS QUALITY OF TRITICALE (xTRITICOSECALE WITTMACK) – FORAGE PEA (PISUM SATIVUM L.) INTERCROP

“…It was determined that the effect of the different mixtures on the RFV was significant, where the highest and lowest RFV was obtained from sole forage pea and sole triticale, respectively. (Kusvuran et al, 2014). Our findings were similar to these results.…”

Effects of Seeding Pattern and Harvest Date of Persian Clover and Annual Ryegrass on Hay Yield and Quality in a Mediterranean Environment

“…Sadeghpour et al (2014) reported that the mixtures of barley with annual medics had higher crude protein yield than pure crop, and it can be concluded that the tested mixture rates and pure legume are significantly different in term of protein content depending on their genetic properties. Our findings are consistent with the results of many researchers reporting that the crude protein yield increases as the ratio of legumes in the mixture increases (Vasilakoglou and Dhima, 2008;Kusvuran et al, 2014).…”

“…In this study pure legume plant had lower ADF content than annual ryegrass and annual ryegrass mixtures with legume. ADF concentrations decreased as the legume proportion increased in the mixtures and similar results have also been reported by Karagic et al (2011); Sadeghpour et al (2014); Kusvuran et al (2014).…”

“…Many research workers emphasized that pure cereal cropping is not a good option to feed livestock due to the lower quality and biomass yield. (Aasen et al, 2004;Karagic et al, 2011 andKusvuran et al, 2014).…”

Hay Yield, Quality and Competition of Hungarian Vetch (Vicia pannonica) and Italian Ryegrass (Lolium multiflorum) Intercropping

“…For all these reasons, while the lowest ADF and NDF ratios were obtained from sole Hungarian vetch planting, followed by 90% Hungarian vetch + 10% Italian ryegrass mixture and they were statistically in the same group. Kusvuran et al (2014) reported similar results in Hungarian vetch and Italian ryegrass mixtures. In mixtures, LER, aggression, and competition ratio are determined to reveal the competition between plants (Dhima et al, 2007).…”
