INFLUENCE OF MANURE TYPES AND NPK 15: 15:15 ON SOIL LOSS DUE TO HARVESTING OF AMARANTH IN OGBOMOSO
Abstract
Soil loss due to crop harvesting (SLCH) is defined as the loss of soil adherent to crops,
loose soil, soil clods and rock fragments that are removed from the field during harvest. The
experiment was conducted at the Teaching and Research Farm of Ladoke Akintola University of
Technology, Ogbomoso. This study was carried out to determine effect of different manures on
growth and yield of amaranth and to quantify soil loss during harvesting of amaranth
Four fertilizer types were introduced, T0 = Control, T1= Poultry manure, T2= Pig
manure, T3= Rabbit manure. The trial was arranged in Randomized Complete Block Design
(RCBD) replicated three times. Data were collected on plant heights, numbers of leaf, stem
girths, total fresh biomass, soil loss and were subjected to Analysis of variance (ANOVA).
The effects of manure on the number of leaves showed that Pig manure had the highest
mean value (30.8 cm) and was significantly (p=0.05) different from other treatment while the
least value (14.8 cm) was obtained from poultry manure.
