APLIKASI BIO URINE DAN PUPUK NITROGEN PADA TANAMAN JAGUNG MANIS (Zea mays sacharata) DI LAHAN RAWA
This research has been conducted in the Faculty of Agriculture experiment station Musi Rawas This study aims to look at the effect of giving cows Bio Urine and various doses of nitrogen fertilizer on the growth and yield of sweet corn in swamp land. This study uses a randomized block design consisting of 2 factors were repeated 3 times. Each treatment unit in a grid with a size of 2 m x 1 m. The treatment in this study are as follows: the first factor treatment biourine B1 = 25 ml / liter of water, B2 = 75 ml / liter of water and B3 = 100 ml / liter of water and treatment factors both doses of nitrogen fertilizer N1 = 100 kg / ha, N2 = 150 kg / ha, and N3 = 250 kg / ha. The results showed the treatment biourine 75 ml / liter of water (B2) showed the best results on plant height. While treatment biourine as much as 100 ml / liter of water (B3) showed the best results at the variable length of the cob, cob diameter, heavy crop cob, cob heavy perplot, heavy wet upper canopy, and wet weight roots. For the dosage of nitrogen fertilizer dose of 150 kg / ha (N2) showed the best results on plant height, weight wet canopy top, ear length, ear cropping weight and cob weight per plot. While the dose of 200 kg / ha (N3) give the best results at the variable wet weight root and ear diameter.
