Yield responses and nutrient uptake of chive as affected by nitrogen, phosphorous, and potassium fertilization.
1995
Wilson H.
Field experiments were conducted on Maraval clay loam (fine, kaolinitic, isohyperthermic Oxic Tropudalfs) and River Estate sandy clay loam (fine loam, micaceous, isohyperthermic Fluventic Eutropepts) in Trinidad and Tobago to determine the effect of rate of nitrogen (N) in the presence and absence of phosphorus (P) and potassium (K) on the growth, yield, and plant tissue nutrient content for chive (Allium spp.) grown for the fresh market. Nitrogen had a significant effect (p < 0.001) on the average number of tillers/plot, the average number of leaf blades/plot and subsequently on the marketable yield (p<0.05) of the crop. Application of low rates of applied N (67 kg/ha) gave the highest values although there being significant differences (p<0.005) between soils with higher values recorded on the River Estate clay loam. On the Maraval clay loam, application of increased N had no positive effect on tissue N except in the presence of P and K fertilizers. Significant differences (p < 0.05) were obtained for the plant tissue nutrient content between treatment and between soils, except in the case of plant tissue K content where no significant differences were obtained between soils.
