Effect of planting hole size and farm yard manure rates on establishment of high density arabica coffee

Investigations of effects of planting hole sizes (15 cm x 15 cm, 30 cm x 30 cm, 45 cm x 45 cm and 60 cm x 60 cm) and (0, 25, 50, 75 and 100 percent) farmyard manure rates on field establishment at high density of compact, disease resistant arabica coffee cv Catimor were carried out at Ruiru and Koru, Kenya. Clean coffee yields, growth and yield components increased significantly with hole size but did not respond significantly to farmyard manure rates. Proportion of grade `A' beans was negatively correlated to the size of the holes and positively correlated to farmyard manure rates. It was concluded that for good coffee establishment, the planting hole size should not be less than 45 x 45 cm and the manure used there in should constitute not more than 50 percent of the mixture with top soil or 1-2 tins (20 l of debes) per hole
