Shukla, G.C. (Ministry of Nat'l Dev. and Agric. (Guyana). Res. Div.)
Varieties tested were Valencia, Ruby and Parson brown. The field design used was a randomized block with 4 replications and the treatments given were: control, N, NPK, NPK and dolomite and NPK and micro-nutrient fertilizer. The effect of fertilizers on mean weight of oranges for all varieties was non-significant; NPK and NPK and dolomite treatments increased the juice content of Parson brown significantly; NPK and dolomite increased the juice content of Valencia and Ruby oranges and increased the pH of Valencia and Parson brown. NPK, NPK and dolomite, and NPK and micro-nutrient increased the number of Valencia, Ruby and Parson brown oranges harvested per tree significantly (at 1 % LSD)
