Response of a castor crop to application of NPK fertilizer



Response of a castor crop to application of NPK fertilizer



Anais do decimo quinto congresso Brasileiro de ciencia do solo, Campinas, SP, Brazil, 14 a 20 de julho de 1975: 189-191



In a field trial in 1972-3, castor was given various combinations of 0, 70 or 80 kg N, 0, 80 or 160 kg P2O5 and 0, 40 or 50 kg K2O/ha. Seed yields were 1.69 t/ha without applied fertilizer. The highest yield was 2.08 t with 80 kg P2O5 + 40 kg K2O/ha and the lowest 1.09 t with 80 kg N + 50 kg K2O/ha.
