摘要
Seed priming is apragmatic, easy approach and an effective technique. It may prove to be an alternate approach to soil and foliar application of micronutrients. In this study, the effect of micronutrient seed priming at different concentrations and combinations was evaluated on the productivity of hybrid maize (DK-6578). For priming maize seeds were soaked for 8h in various solutions of zinc (0.5%), boron (0.01%), manganese (0.01%), boron+zinc (0.01%+0.5%), boron+manganese (0.01%+0.1%), and boron+zinc+manganese (0.01%+0.5%+0.1%). For comparison, seeds were also soaked in simple water (distilled), i.e. hydropriming, and untreated seeds were taken as control. Seed priming in all the treatments substantially induced the early emergence of maize compared to control. Likewise, highest grain yield, biological yield, cob length, grain rows per cob, grains per cob and 1000-grain weight were observed in plants raised from primed seeds, while boron+zinc+manganese priming (0.01%+0.5%+0.1%) was the best treatment. Similarly, maximum boron (77.60mg/kg) and protein contents (10.82%) were observed in boron+zinc+manganese (0.01%+0.5%+0.1%) primed seeds, followed by boron+zinc (0.01%+0.5%). In conclusion, different seed priming strategies improved emergence, yield and quality of maize. The combined application of boron, zinc, and manganese (0.01%+0.5%+0.1%) for seed priming was the most effective treatment technique. ZusammenfassungSaatgutvorbehandlung ist eine pragmatische, leicht zugangliche und effektive Technik, die ein alternativer Ansatz fur die Boden- und Blattaufbringung von Mikronahrstoffen sein kann. In dieser Studie untersucht wurde der Effekt einer Saatgutvorbehandlung mit Mikronahrstoffen in verschiedenen Konzentrationen und Kombinationen auf die Produktivitat von Hybridmais (DK-6578). Fur die Aufbereitung wurden Maissamen 8h lang in verschiedenen Losungen aus Zink (0,5%), Bor (0,01%), Mangan (0,01%), Bor+Zink (0,01%+0,5%), Bor+Mangan (0,01%+0,1%), Bor+Zink+Mangan (0,01%+0,5%+0,1%) quellen gelassen. Zum Vergleich wurden Maissamen in destilliertem Wasser quellen gelassen (Hydropriming), und unbehandeltes Saatgut diente als Kontrolle. Die Saatgutvorbehandlung fuhrte im Wesentlichen dazu, dass der Mais im Vergleich zur Kontrolle fruh aufging. Die hochste Kornernte, der hochste biologische Ertrag, die gro ss te Kolbenlange, die meisten Kornreihen pro Kolben, die meisten Korner pro Kolben und die hochste Tausendkornmasse wurden bei Pflanzen beobachtet, die aus vorbehandeltem Saatgut hervorgingen. Dabei war die Kombination Bor+Zink+Mangan (0,01%+0,5%+0,1%) die beste Behandlungsmethode. Ebenso wurden maximale Bor- (77,60mg/kg) und Proteingehalte (10,82%) bei mit Bor+Zink+Mangan (0,01%+0,5%+0,1%) vorbehandelten Samen beobachtet, gefolgt von Bor+Zink (0,01%+0,5%). Zusammenfassend lasst sich sagen, dass verschiedene Strategien zur Saatgutvorbehandlung das Aufgehen, den Ertrag und die Qualitat von Mais verbessern. Dabei hat sich die Kombination von Bor, Zink und Mangan (0,01%+0,5%+0,1%) als die effektivste erwiesen.
