Influence of Rate and Time of Poultry Manure Application on Yield and Yield Components of Tomato Varieties in the Semi-Arid Environment of Nigeria
Abstract
A Field trial was carried out in the Nigerian savanna at the Federal University Dutsin-Ma, Teaching and Research Farm, Badole, and Danja. The two trials were conducted in the dry season of 2019/2020 to assess the influence of applying poultry manure at different rates and times on tomato varieties' yield and yield components. The treatments consisted of two tomato varieties (UTC GRAPTOR and SUDANA), four poultry manure application rates (0, 5, 10, and 15 t ha-1), and three poultry manure application times (two weeks before transplanting, at transplanting, and two weeks after transplanting). The experiment was laid out using randomized complete block design (RCBD) with three replications. UTC GRAPTOR (13500 Kg ha-1) gave a significantly higher fruit yield than SUDANA (12480 Kg ha-1) at Badole only. Application of 15 t poultry manure ha-1 performed significantly (P<0.05) higher than other poultry manure rates on tomato yield components. Application of 15t ha-1 poultry manure produced significantly (P<0.05) higher tomato fruit yield, 13500 and 13440 Kg ha-1, for Badole and Danja, respectively, than what was obtained with application of either 0, 5, or 10t ha-1 poultry manure. Poultry manure application at two weeks before transplanting gave significantly (P<0.05) higher tomato fruit yield and yield components except fruit diameter. Hence, applying of 15t poultry manure ha-1 to soil grown with UTC GRAPTOR tomato variety at two weeks before transplanting is the most appropriate for production of tomato in the study areas.
