Effect of morphological components on the herbage yield and quality of quinoa (Chenopodium quinoa Willd.) grown at different dates

Abstract

Introduction Quinoa (Chenopodium quinoa Willd.), which is also known as pseudo-grain, is an annual plant that has been cultivated for thousands of years in the Andes (Cusack, 1984). The seeds of quinoa are rich in protein, minerals, carbohydrates, and antioxidant compounds when compared to cereals, such as corn, oats, rice, and wheat (Repo-Carrasco et al., 2011; Stikic et al., 2012; Ruiz et al., 2014), and they are usually utilized as human food (Bhargava et al., 2007). Therefore, quinoa has been evaluated in terms of its seed performance in most of the previouslyconducted scientific studies (

Phenotypic diversity of agromorphological characteristics of quinoa (Chenopodium quinoa Willd.) germplasm in Colombia

“…The length of panicles in quinoa plants depends on the growth and differentiation processes that occur in the apical meristem (Garcia et al, 2019). These processes are determined by the genotype, inflorescence type, and fertility conditions in the soil, among others (Temel and Keskin, 2020). Panicle lengths between 22 and 40 cm have been reported (Lopez et al, 2012) and, in this study, we found panicles between 12 and 45.6 cm in length.…”

“…Panicle colors changed during physiological maturity. Hence, other studies on quinoa reported significant decreases in plant height, stem thickness, number of branches, and panicle ratios, as the sowing time progressed (Hirich et al, 2014;Temel and Keskin, 2020). Montes et al (2018) reported that the wide range of colors in the materials evaluated is because the panicle is covered by granular vesicular pubescence rich in calcium oxalate with white, pink, and purple tones that contribute to panicle coloration of each variety.…”

The Effects of Different Sowing and Harvesting Times on Hay Quality of Mountain spinach (Atriplex nitens) Grown in Arid Conditions

“…Harvest dates of plants according to sowing times and harvest time are given in Table 1. Plants were harvested 10 cm above the soil level after leaving 50 cm at the beginning of the plot and one row at the plot edges as edge effects (Acar et al, 2019b;Kır and Temel, 2017;Temel and Keskin, 2020). From the harvested plants, 10 plants were selected to represent the parcel and after drying for a while in the shade, they were allowed to dry in the drying oven at 70 o C until their weight stabilized.…”

“…Studies have shown that Atriplex nitens plant has high nutritional values for animals (Watson, 1990;Rabbimov et al, 2011;Acar et al, 2019b). Nutritional value and digestibility of feed are significantly affected by plant species and varieties, environmental factors, cultural practices, sowing times and harvest times (Buxton, 1996;Aganga et al, 2003;Collins and Fritz, 2003;Özyiğit and Bilgen, 2006;Önal Aşcı and Acar, 2018;Temel and Keskin, 2020).…”

Determination of Mineral Content of Seeds Belonging to Different Quinoa Varieties and their Evaluation for Daily Mineral Requirements of Laying Hens

“…), an annual pseudo cereal, is seen as an alternative crop in human and animal nutrition in many regions of the World since it adapts well to different climate and soil conditions and has a high nutritional value (Jacobsen et al, 2007;Geerts et al, 2008;González et al, 2012;Abtahi Adolf et al, 2013;Ruiz et al, 2014;Tan and Temel, 2017a;Tan and Temel, 2018;Temel and Yolcu, 2020). The fact that the seeds and vegetative parts (leaf + stem) having quality fiber, balanced amino acid, high protein and energy content is an important factor in the consideration of the plant as a valuable alternative source of nutrition (González et al, 2012;Rojas and Pinto, 2015;Tan and Temel, 2017b;Tan and Temel, 2019;Temel and Keskin, 2020;Temel and Tan, 2020). is important to determine the most suitable varieties in terms of mineral composition by means of adaptation studies.…”
