Productive Traits of Triticale Depending on Sowing Rate and Meteorological Conditions in Tested Years

Abstract

SUMMARYThe results of the examination of sowing density and meteorological conditions on productive traits of several genotypes of winter triticale are presented in this paper. The examination was conducted in the vicinity of Bijelo Polje, in the northern part of Montenegro in the period 2009-2012. The experiment, set in randomized block system with three replications included five varieties of winter triticale (Odysseus, Kg-20, Triumph, Rtanj and Tango) and two sowing rates (density) -600 and 800 germinated seeds per m -2 . Common agronomical practices were used in the experiment, with the application of NPK fertilizer combinations 60:80:80. The following parameters were assessed: the number of grains per spike, 1000 grain weight, hectoliter weight and grain yields of triticale.The results of the examination showed significant differences in reproductive traits of winter triticale, depending on the variety, sowing density and weather conditions in the years of research. Variety Tango had the highest average grain yield (5610.0 kg ha -1 ) and 1000 grain weight (48.4 g), while Kg-20 had the lowest grain yield (4465.6 kg ha -1 ). Variety Odysseus had the highest number of grains per spike (38.5), while the highest value of hectoliter weight was determined in variety Triumph. Significantly higher yields were achieved by applying higher sowing density in comparison to the standard application of lower sowing density. The results of the examination showed that the demonstrated differences of observed parameters of the varieties which were included in this examination are the results of the specificity of varieties, of agro technical practices and climatic conditions in the years of study.

EFFECT OF SEED SIZE AND SEEDING RATES ON YIELD ATTRIBUTES OF TRITICALE Var. ADMIRAL

“…Whereas the lowest value was recorded for the seeding rate 200 with the light grade. These accord those of Biberdžić et al (15) and Bokan and Malesevic (17), whom referred to reduction of the sowing rate, resulted in increase in number of grains per spike. Results resemble to Habibullah et al (38) who also referred target seed rate have such effect to number of grain per spike.…”

“…The data represented in Table (13) Protein, % Protein content as percentage was significantly affected by seeding rate, seed grade size and their interaction for the first season (Table 16). Protein % at 200 seeding rate surpassed other rates (12.04), but the inferior was with the rate 300.…”

“…Water insufficiency amid the period of anthesis is critical minute to typical cereal production, causing critical yield losses (27). Productive traits of winter triticale in term of spike length, number of grains per spike, 1000 grain mass and grain yield have significant effect by meteorological conditions in the years of research (13). Excessive surplus or deficit of rains and by large temperature amplitudes cause severely for the cereal yields (59).…”
