Abstract
This study aimed at improving the growth in maize plants by supplementing the standard fertilisation regime with Petrobio fertiliser. The experiment was conducted in Amor-amor hamlet, Gumantar village, Kayangan sub-district, North Lombok district (Indonesia), testing two levels of standard fertilisation doses (100% and 75% of maize fertilisation doses of 380 kg ha-1 Phonska + 500 kg ha-1 urea) and four doses of Petrobio (0, 20, 40 and 80 kg ha-1). The experiment was designed with a factorial randomised block design with three replications. The variables observed were plant height, number of leaves, fresh and dry biomass weight, canopy interception of sunlight, and tissue concentrations of N, P and K. Data were subjected to analyses of variance and regression between particular variables. The results showed that, compared to without Petrobio fertiliser, the application of 80 kg ha-1 Petrobio fertiliser almost doubled the dry weight of maize plants, increased light interception by around 5%, and increased the total concentrations of N, P and K in tissues at least by 40%. There were strong relationships between Petrobio doses and dry weight of maize plants, and the concentration of N, P, and K in the maize plant tissues.
