Abstract:
There is a growing popularity of organic farming in the modern era because of its potential contributions in sustaining crop production without impairing the natural condition of the environment. In this study, the physiological parameters of sweet corn applied with rates of indigenous microorganisms (IMO) 7 such as: (120 kg N - 90 kg P2O5 - 60 kg K2O, IMO 7 at 7.5 t ha-1, 15 t ha-1, and 22.5 t ha-1) and biofertilizers - fish amino acid (FAA), fermented plant juice (FPJ), and fermented seaweed (FS) were evaluated at different crop stages at 45, 55, 65, and 75 days after planting. The study was conducted in a 4 x 4 factorial in Randomized Complete Block Design (RCBD) with three replicates. Rates of IMO 7 significantly influenced on the crop growth rate (CGR) at 55-65 days after planting (DAP), and carbon productivity (CP) while biofertilizers influenced on weight per ear, the number of kernels per ear, ear yield, and leaf area ratio (LAR) at 65 DAP. Synthetic fertilizers (120 kg N, 90 kg P2O5, 60 kg K2O) and IMO 7 at 22.5 t ha-1 gave the highest carbon productivity at harvest of 10.58 t ha-1 and 10.38 t ha-1, respectively. Fermented seaweed gave the highest ear yield, weight per ear, and the number of kernels per ear. IMO 7 at the rate of 22.5 t ha-1 gave the highest CGR at 19.5 mg g-1 day-1 or 25.64% higher than those plants treated with the minimum rate of 7.5 t ha-1. The results of the study provide information on the potentials of using IMO 7 in combination with fermented seaweed as organic fertilizers for sustainable sweet corn production.
Keywords: Biofertilizer, carbon productivity, IMO 7, physiological, sweet corn.
