Nurcihan Hacıoğlu Doğru, Okan Acar. Poulard wheat, Triticum turgidum L. Increasing seeding rates from 100-200 kg ha–1 increased number of days from sowing to 50% heading from 70.5-73.17 (Table 1). Above ground dry biomass yield (kg ha–1): Analysis of variance showed that the main effect of seed rate had a highly significant effect on above ground dry biomass yield. Box 249, Holeta, Ethiopia. very long, narrow, and hard. The highest plant height (104.27 cm) was recorded from 100 kg ha–1 seed rate however, statistically similar result was observed between 100, 125 and 150 kg ha–1 seed rates while, the lowest plant height (101 and 100.78 cm) was recorded from seed rate of 175 and 200 kg ha–1, respectively, which were statistically at par with each other (Table 1). In contrast, Melaku (2008) reported that increasing levels of seed rate promoted early physiological maturity of tef. Over recent decades, several types of ancient grain varieties have been reintroduced through organic farming systems. Furthermore, variety Digelu was late in days to 50% heading over variety Kakaba by 27%. (2007) who reported that individual genotypes responded differently to spike length for varying seeding rates in wheat. Kernels are white or red, (Perc.) ex Ascb. About 95% of wheat produced worldwide is common wheat; it is the most widely grown of all crops and the cereal with the highest monetary yield. Diploids (2n = 14, AA) 3.1.1. On the other hand, variety Digalu produced best yield at 175 kg ha–1 (Table 5). At the apex a brush consisting of Club wheat, Triticum aestivum subspecies compactum (Host) MacKey. Spikelets fall from the fragile spike at maturity. 1 Tigray Agricultural Research Institute, Alamata Agricultural Research Center, Tigray, Ethiopia A factorial arrangement in Randomized Complete Block Design (RCBD) with three replications was used. (1998) and Lafarge et al. Furthermore, Sadowska et al. whole or after coarse grinding. Wheat has been a food crop for mankind since the beginning of agriculture. removed mechanically and the resulting product consists essentially of the (2006) found significant differences among different genotypes of wheat in grain protein content. very shallow, narrow crease, and a short brush. Production in the United States was 1,524,340,000 bushels in 1967. these reasons it has substantially disappeared from commercial production. However, Mollah et al. In agreement with this, Shahzad et al. the germ is a valuable addition to feed concentrate. Shot wheat, Triticum aestivum subsp. Box 249, Holeta, Ethiopia. From the result of this study, the use of 125 kg ha–1 seed rate for variety Danda’a; 150 kg ha–1 for varieties Shorima and Kakaba and 175 kg ha–1 for variety Digalu can be recommend tentatively for Kulumsa area. 14, No. In awned varieties, the awns or beards are at the terminal Stems vary in height but are generally stiff. is a very diverse and widely adaptable cereal crop. Kernels are red, long, flattened, with a sharp tip The result was in agreement with Jaama et al. This wheat is grown in the Mediterranean Area and the Near East, but not in the This could be due to its longest spike length of 10.5 cm, which plays a vital role in wheat on the number of grains per spike and finally the yield (Shahzad et al., 2007). Plant height (cm): The result showed that plant height was highly significantly (p<0.01) affected by the main effect of variety and seed rate. Tagesse Abera, Ketema Belete and Tam ado Tana (2018). the elongated stems in late spring. Popul … Thus, variety shorima at seed rate of 150 kg ha–1 exceed variety Danda’a at seed rate of 200 kg ha–1 by about 29.52% in number of kernels per spike. alcoholic beverages. Triticum polonicum L. Six varieties of T. polonicum were identified in Georgia. These results indicated that each variety must not be sown at equal seed rate. after threshing. kind and growing conditions. Number of Kernels per Spike (NKS): It was taken from ten randomly selected spikes per net plot at harvest and was averaged to per plant basis. As seed rate increased from 125-200 kg ha–1, the spike length was declined by 8.57%. As a feed grain, wheat is fed to livestock either Thus, it is essential to determine the optimum seed rates for newly developed bread wheat varieties for the maximum yield. (2002) also reported that the maximum plant height (103.3 cm) was observed with seed rate of 150 kg ha–1 followed by 175 kg seed ha–1 which produced plants of 93.2 cm in wheat. United States. Shot wheat is grown in Northwest India, but not commercially in the United States. Furthermore, the interaction effect of variety and seed rate significantly affected thousand kernels weight, number of effective tillers and number of kernels per spike and grain yield. Similarly, Bordes et al. It could be due to the reason that the use of low seed rate in wheat shortened the intervals between the growth phases by facilitating the physiological activities of crops due to the accessibility of ample resource. About 8 varieties are spelta L.) grown under drought conditions has received little attention. We wish to thank Madda Walabu University for financial support. Since nearly all wheat is now combined, with the straw scattered awned. Grain Yields (GY): The GY was recorded from nine center rows and then adjusted to 12.5% moisture level. is a winter annual with loose, flattened spikes bearing long, stiff awns. are medium long, slender and hard or flinty. This is the source of most of the They may be either spring or States for feed on a limited acreage but now has substantially disappeared from Grain yield (kg ha–1): The result regarding grain yield showed that there were highly significant (p<0.01) differences in grain yield among wheat varieties and seed rates. Some wheat is cut for hay. lateral branches termed tillers. compound or branched. In areas with rigorous winter climates it is mainly spring seeded. A number of bread wheat varieties differing in height, maturity and tillering capacity have been developed in Ethiopia. Quality test of local varieties and genotypes introduced wheat (Triticum aestivum L.) during four planting dates 8045 The results showed that there is a significant interaction between planting dates and varieties in this trait, as the combination (type Iraq X second date) gave the highest average weight of … Treatments and experimental design: Twenty treatment combinations off our bread wheat varieties (Digalu, Danda’a, Kakaba and Shorima) and five seed rates (100, 125, 150, 175 and 200 kg ha–1) were tested.
