GROWTH AND YIELD OF ONION (Allium cepa L.) AS INFLUENCED BY STRAIGHT AND COMBINED APPLICATION OF....

During the 2011-2013 dry seasons, field studies were done at the Fadama Teaching and Research Farm of the Kebbi State University of Science and Technology Aliero, which is located at Jega (Lat. 12o 12' N and Long. 4o 22' E) in the Sudan savannah agro-ecological zone. The goal was to see how onion (Allium cepa L.) responded to inorganic and organic soil amendments, both separately and together. Six (6) soil amendments, each designed to give 120 kg Nha-1 using a compound fertiliser NPK [15:15:15], farm yard manure, and six-month old poultry manure from an automated battery cage system were used in the treatments. When the recommended nitrogen dose of 120 kgNha-1 was applied using 100 percent NPK (800 kgNPK [15:15:15/ha]) or a 50:50 ratio of NPK and PM, onion plant height (10 WAT), mean bulb diameter, mean bulb weight, and bulb yield (t ha-1) were all significantly enhanced. Based on the findings of this study, it was determined that a 50:50 combination of organic and inorganic soil amendments in the form of NPK compound fertiliser and poultry manure could be used to increase onion bulb yield, given the complementary role of poultry manure in improving soil physical quality.
