The research explored adaptability maize seed coating agent in spring sowing and effects of ultra-fine powder shaped areas in northeast China. The results showed that germination potential and rate both improved around 5% and the num- ber of root increased by 4% in the treatments with ultra-fine powder shaped maize seed coating agent compared with the control group without seed coating. What's more, the treatments with ultra-fine powder shaped maize seed coating agent took advantages in terms of fresh weight of seeding, stem diameter, and dry weight. It is notable that control effects on underground insects performed the best, with per- centage over 94%, which is more excellent relative to other agents in markets. Therefore, ultra-fine powder shaped maize seed coating agent can be widely applied in spring sowing areas in northeast China, without side effects. 展开更多

Using the commercial seeds of two hybrid rice varieties including Lu- liangyou 996 and Liangyoupeijiu as the materials, four specific gravity-based seed grading treatments, Le., the specific gravity of 〈1.0 (T1), 1.0-1.09 (T2), 1.1-1.19(T3) and ≥1.2 (T4), by selection with different saline solutions, and the control without seed grading (CK) were designed to study the effects of seed grading on seed germination, seedling emergence, seedling quality and grain yield. The results showed that the treatments of T2, T3 and T4 had higher or significantly higher seed germination rate, germination index and vigor index, seedling emergence rate and adult seedling rate than the CK, while T1 had significantly lower values of these traits than the CK. Compared with the CK, the number of spikelets per pani- cle was found to be the main reason for the yield increase of these treatments with high seed viability. 展开更多

Germination began 10 d and lasted 67 d. The mean sprouting rate of the Kponan full season harvest tuber was 78.1% compared to 94% in Krengle. However, the tuber germination was progressive from head to tail with a linear evolution of the top fragments with sprouting rate up to 90% similar to Krengle. The median and distal portions sprout two and three weeks later with final raising rates reaching 68% and 71%, respectively. The full season tuber of Kponan sprouts with a good rate gave good yields for any portion of the tuber. It had a sprouting gradient oriented from the proximal portion to the distal one, while yield was better for medium seeds. The sprouting delays two weeks between proximal and medium portions and three weeks between proximal and distal portions were acceptable with regards to the total cycle of eight to nine months period. Thus, its small tubers could be planted as well as the top portion of big tuber. In terms of yield, Kponan medium seed gave the best yield 34.25 t/ha and the whole Kponan tuber yield was more than Krengle. That led to a better multiplication factor for Kponan full season tuber. The type of tuber, if available, could be used as seed for yam production. That could improve its distribution and contribute to food security. 展开更多

Aiming to optimize the beer production process by improving the properties of beer and reducing production costs at the J.S.C. "Birra Peja" brewery, Peja, Kosovo, this study did an evaluation of beer produced using six different malts. Four of the six studied malts were produced in four European countries: Ukraine, Croatia, Serbia and Kosovo; and, the other two malts were obtained from two (2) 30:70 proportion mixtures: one from Kosovo and Ukraine and another one from Kosovo and Croatia. Chemical, microbiological, sensory and tasting analyses were carried on beers produced by these malts. The study included three working groups from: "Birra Peja"; the Agricultural University of Tirana, Albania and "Union Brewery", Ljubljana, Slovenia. Chemical and microbiological tests were based on methods under the EBC (European Beer Convention) and MEBAK (Mitteleurop^iische Brautechnische Analysenkommision e.V.) guidelines. The analyses and assessments made for the quality of beer have come to the conclusion that beer produced by Croatian origin malt corresponds to a better quality beer. 展开更多
