| Abstract Mombasa grass is very demanding and responsive to soil fertility. The objective of the present study was to evaluate forage production and the correlation among crude protein and the green color index of leaves of Megathyrsus maximum cultivar Mombasa in function of nitrogen levels. The study was conducted using 5 dm-3 pots in a greenhouse at the Universidade Estadual Paulista - UNESP, Jaboticabal, São Paulo. The experimental design consisted of randomized blocks with five treatments and four replications. Treatments were nitrogen rates (0, 62.5, 125, 250 and 500 mg dm-3 of N), corresponding to 0, 125, 250, 500 and 1000 kg ha-1 of N. We evaluated the production of grass dry matter, the green color index, the accumulation of nitrogen and crude... |

| Abstract The glycerin by-product of the production of biofuels (biodiesel) has possibility of agricultural use, but the scientific information is restricted. The objective of this study was to assess the effect of glycerin rates in the absence and presence of potassium fertilization on soil microbial activity, nutrition and production of beet (Beta vulgaris). The experiment was carried out in a greenhouse at Universidade Estadual Paulista, Jaboticabal, Brazil, using beet cv. Early Wonder, grown in pots with samples of Alfisol. The experimental design was randomized block, treatments were 0, 50, 100, 200 and 400 m3 ha-1 of glycerin, in the absence and presence of potassium (150 mg dm-3), with four replicates. Electrical conductivity, respiratory activity,... |
