RESUMO:A cultura do sorgo é cultivada no Brasil no período de segunda safra, onde sua produção é destinada à produção de grãos para fabricação de rações e concentrados, destinando-se também à produção de etanol e silagens, substituindo o milho em muitos casos. Com isso, a busca por aumento de produtividade torna-se fundamental, e neste âmbito as formas de adubação são de grande importância. Desta forma, o objetivo deste trabalho foi avaliar a eficiência de diferentes formas de adubação com formulado NPK na cultura do sorgo granífero em semeadura tardia e verificar a ocorrência de correlação entre as variáveis. O experimento foi realizado no município de Tangará da Serra-MT, utilizando a cultivar Embrapa BRS 332. O ensaio foi constituído de quatro tratamentos referentes a formas de adubação do formulado NPK 26-28-08 e quatro repetições dispostos em um delineamento de blocos ao acaso, sendo: sem adubação (0 kg ha FERTILIZATION FORMS OF SORGHUM IN SEEDING LATE SUMMARY:The sorghum crop is grown in Brazil during the second season, where its production is destined to the production of grains for the production of feed and concentrates, also being intended for the production of ethanol and silage replacing corn in many cases. Thus, the quest for increased productivity becomes crucial in this context forms of fertilizers is of great importance. Thus, the objective of this study was to evaluate the efficiency of different forms of NPK fertilizer formulated in the sorghum crop in late sowing and verify the occurrence of correlation between the variables. The experiment was conducted in the city of Tangara da Serra-MT, using the BRS 332 cultivar Embrapa. Testing consisted of four treatments regarding forms of fertilization NPK 26-28-08 and four replications arranged in a randomized block design Actually, being: without fertilization (0 kg ha -1 ), fertilization in rows (350 kg ha-1) row fertilization (250 kg ha -1 ) + topdressing (100 kg ha -1 ) and topdressing (350 kg ha -1 ). The final stand was composed of 15 plants by linear meter. For harvest were randomly selected 10 plants useful for the track area and then be oven dried. The highest yields were obtained with the fertilization of 350 kg ha -1 of potassium in the crop row and fertilization of 250 kg ha -1 in rows over 100 kg ha -1 in coverage, and 2.589,75 kg ha -1 and 3.607,15 kg ha -1 , respectively.
