The effect of different row spacing and intra-row spacing on hay yield and quality in quinoa (Chenopodium quinoa willd.)

This study was carried out in order to determine the effects of different row spacing (17.5, 35, 52.5 and 70 cm) and intra-row spacing (10, 20, 30 ve 40 cm) on plant height, stem diameter, herbage yield, dry matter ratio, dry matter yield, leaf ratio, stem ratio, bunch ratio, crude protein ratio, crude protein yield, acid detergent fiber (ADF) ratio, neutral detergent fiber (NDF) ratio, relative feed value (RFV) of quinoa (Chenopodium quinoa Willd.) plants grown under irrigation condition. The research was established according to a factorial experiment based on randomized complete block design with three replications in the Melekli Research Station of the Agricultural Practice and Research Center of Igdır University in 2017. While are significant the effect of row spacing on the parameters such as plant height, stem diameter, herbage yield, dry matter ratio, dry matter yield, leaf ratio, stem ratio, bunch ratio, crude protein ratio, crude protein yield, neutral detergent fiber (NDF) and relative feed value (RFV) of quinoa, the effect on acid detergent fiber (ADF) ratio was found to be insignificant. Effect of intra-row spacing on stem diameter, herbage yield, dry matter ratio, dry matter yield and crude protein yield of quinoa were significant. For other research criteria, it has been determined that the effects of intra-row spacing changes will not be affected. In Igdir province, it was determined that it would be appropriate of sowing at 17.5 cm row spacing and 10 cm intra-row spacing of quinoa in order to highest herbage yield, dry matter yield and crude protein yield. If the kinoa plants are sowing at 17.5 cm row spacing and 10 cm intra-row spacing, 8750.7 kg da-1 herbage yield, 2676.4 kg da-1 hay yield and 398.8 kg da-1 crude protein yield can be obtained in the quinoa plant.
