Pengaruh Pemberian Dosis KNO3 terhadap Pertumbuhan, Produksi, dan Serapan Kalium Tanaman Jagung Manis (Zea Mays Saccharata Sturt)
Abstrak: This study aimed to
determine the effect of KNO3 dosage fertilizer on the growth, production and
potassium uptake of sweet corn varieties Talenta. This research was conducted
in December 2015 to February 2016. Thisstudy used a randomized block design
with 6 treatments and 3 replications. The treatments were control, KNO3
fertilizer with a dose of 50 kg ha-1, KNO3 fertilizer with a dose of 100 kgha-1,
KNO3 fertilizer with a dose of 150 kg ha-1, KNO3 fertilizer with a dose of 200
kg ha-1 andKNO3 fertilizer with a dose of kg ha-1, The results showed that KNO3
fertilizer impacted onplant height, leaf number, leaf area index, dry weight,
number of rows per ear, seed numberper row, total production, and uptake of
pottasium. KNO3 fertilizer treatment at a dose of 132 kg ha-1 gave the best
result of growth, production and best potassium uptake. The use of KNO3 could
be an alternative fertilizer for Potassium fertilization of sweet corn.
