THE EFFECT OF N, P, K ON SOIL CHEMICAL COMPOSITION AND YIELD OF ROBUSTA COFFEE (COFFEA CANEPHORA PIERRE)

THE EFFECT OF N, P, K ON SOIL CHEMICAL COMPOSITION AND YIELD OF ROBUSTA COFFEE (COFFEA CANEPHORA PIERRE)

One hundred and twenty-eight soil were in 1978 from within 30cm depth of 64 NPK treated plots. A 4 x 4 x 2 NPK trial replicated 2 times commenced in 1972. Three harvests of coffee berry were collected from the treated plots in 1978. Values of coffee yield were correlated with resultant of soil N, P,...
