Pengaruh Dosis Asam Giberelat dan Pupuk Boron terhadap Produksi dan Mutu Benih Jagung (Zea mays L.)

Abstract

Corn is a food crop that is in great demand, because corn is the second source of carbohydrates after
rice, therefore the demand for corn continues to increase from year to year. The purpose of this study
was to determine the interaction between the dose of gibberellic acid and boron fertilizer on the
production and quality of corn seeds. This research was conducted at the Experimental Farm of
Jember State Polytechnic from August to November 2022. This study used a factorial randomized
group design (RGD) that was repeated 3 times. The first factor was the dose of gibberellic acid
consisting of 3 levels, namely G1 (15 DAP), G2 (15 and 30 DAP), G3 (15, 30, and 45 DAP). The
second factor is the dose of boron fertilizer consisting of B1 (10 kg/ha), B2 (20 kg/ha), B3 (30 kg/ha).
Observational data were statistically analyzed using ANOVA, if the results showed significantly
different effects then continued with the DMRT level of 5%.. The results showed that the treatment
interaction between the application of gibberellic acid 15, 30, and 45 DAP and boron fertilizer 30
kg/ha gave a significantly different effect on the parameters of seed weight per cob 119.62 gr, the
number of seeds per cob 416.61 grains, seed production per hectare 5.78 tons/ha, and the weight of
1000 seed grains 315.42 gr.
