Pengaruh Aplikasi Vitamin B1 terhadap Pertumbuhan dan Hasil Produksi Beberapa Varietas Tanaman Jagung Manis (Zea mays saccharata Sturt.)

Abstract

Sweet corn (Zea mays saccharata Sturt.) is a strategic food commodity that plays an important role in food security and has high economic value. Demand for sweet corn is increasing by around 5.7% per year in line with population growth and awareness of its nutritional benefits. The advantages of sweet corn are its short planting cycle and higher selling price compared to regular corn. This study aims to evaluate the effect of vitamin B1 supplementation on the growth and yield of several sweet corn varieties (Bonanza F1, Magenta, and Talenta). The study was conducted on the land of the Faculty of Agriculture Universitas Sumatera Utara Medan, using a Factorial Randomized Block Design with two factors: variety and vitamin B1 treatment (none, 1% soaking for 6 hours, and 1% spraying 4 times). The results showed that vitamin B1 supplementation had a significant effect on cob length. Variety affected plant height as well as cob length and weight without husks. The interaction between vitamin B1 and variety also had a significant effect on plant height at 2 MST.
