Abstract

At the Instituto de Zootecnia, Nova Odessa SP, it was studied a mixture of sorghum with pigeon pea for silage production. A complete randomized block design with 3 replications was used, and the treatments were: 1- sorghum + pigeon pea (sorghum seeds mixed with 00-20-00), 2- sorghum alone (sorghum seeds mixed with 00-20-00), 3- sorghum alone (sorghum seeds separated from the 00-20-00, 4- sorghum + pigeon pea (sorghum seeds mixed with 00-20-20), 5- sorghum alone (sorghum seeds mixed with 00-20-20) and 6- sorghum alone (sorghum seeds separated of the 00-20-20. A surface applied dressing (40 days after planting) with 20-00-20 was done in the treatments 1, 2 and 3 and ammonium sulphate was used in the treatments 4, 5, and 6. An decrease of 26.7% in the sorghum density was observed as fertilizers were mixed with the sorghum seeds. The use of 00-20-00 at the planting day resulted in 21.5% increase in the sorghum density when compared with 00-20-20. The fertilization more appropriated to this mixed crop was: 00-20-00 during the crop seeding, and 20-00-20 forty days after planting. The mixture did not differ from the crop alone m dry mater yield. However the mixed crop yielded 51.6% more crude protein than the sorghum alone and pigeon pea contributed with more than 50% of the total crude protein.
