Evaluation of NDVI, SPAD values and yield of two different maize (<i>Zea mays</i> l.) genotypes under foliar fertilisation

Ensuring global food security has become a matter of great concern with the constantly increasing population growth, resulting in rising demands. Simultaneously, climate change and land degradation pose major risks to agricultural production. Maize is one most produced crops globally maize yields must be increased meet population’s needs. Fertilisation considered indispensable for crop growth development. Foliar fertilisation, unlike root enables rapid access nutrients plants while sustaining environment. Our research was carried out at Látókép 2021, where, foliar sprays Natur Plasma T biostimulant, Active complex fertiliser, Zinc Sulphur Mono additives were applied 8-leaf stage on two hybrids, Mv 352 (FAO 350) Anissa 510). The main objectives examine treatment’s effect critical phenophases (12-leaf stage, silking, maturity), besides determining its impacts harvested yields. Based our findings, had positively influenced NDVI SPAD values both crops. Furthermore, comparison control plots, yield 9% higher, that 5.4% higher. Consequently, highest 21.345 t/ha, i.e. 2.8 tons higher than obtained by 352. Moreover, treatment their thousand-grain weight. Thereby, study demonstrates efficiency fertilisation method improving vegetative development addition productivity enhancing final yield.
