The effect of biofertilizer and double row 2:1 planting system on hybrid corn growth and yield on dry land acid soils in Lampung

Abstract

One of the functions of biofertilizers containing live microbes is that they can stimulate plant growth. The study aims to determine the growth and production of hybrid corn plants with the application of biofertilizers and jajar legowo planting systems. The study was conducted at Natar Experimental Station, South Lampung Regency in February 2017 until June 2017. The study used a Randomized Block Design (RBD) of 5 Bio-Triba biofertilizers with treatments; B0 (manure/control), BT-1 (25 ml/l), BT-2 (10 ml/l), BT-3 (15 ml/l), and BT-5 (20 ml/l). The spacing between corn rows used by Jajar Legowo 2:1 is 20 cm x 50 cm - 100 cm with 1 seed per hole, 5 replications (25 trial plots), and the population was 66,000 plants/ha. The dose of chemical fertilizer used was Urea 350 kg/ha, SP-36 200 kg/ha and KCl 100 kg/ha and 1 ton of rock phosphate. The results showed that the application of biofertilizer had a significant effect on the components of yield (weight of dry seeds and weight of 100 corn grains) but did not significantly affect growth components (plant height, number of leaves) compared to non-biological fertilizer, using cow manure.
