EVALUATION OF THE EFFECT OF VARYING LEVELS OF PHOSPHORUS AND POTASSIUM ON YIELD COMPONENTS AND.....

The trial, which took place at the Kogi State University Students' Research and Demonstration Farm (latitude 7° 30' and longitude 7° 09' E), Anyigba in Nigeria's Southern Guinea savanna agro ecological zone, aimed to determine the effects of varying levels of phosphorus (0, 60, 120, 180, and 180 kg/ha) and potassium (0, 30, 60, 80, 90 kg/ha) on tomato yield components and fruit yield in order to An RCBD experiment comprised of five fertiliser rates that were replicated four times. Various macro nutrients were clearly limiting the soil of the testing site, according to laboratory results. Except at 2WAT, the effect of phosphorus and potassium on growth parameters measured (plant height, stem girth, number of leaves, and number of branches) was significant at 4, and 6WAT, according to data obtained on crop growth parameters (plant height, stem girth, number of leaves, and number of branches). P and K fertiliser application had a substantial impact on yield components (fruit length, diameter, and weight) as well as fruit yield, with a greater reaction as the amount of P and K fertiliser rose. The highest responses were seen when 180 kg P/ha+90 kg K/ha was applied. Furthermore, when evaluating fertiliser input returns, the application of 180 kg P/ha+90 kg K/ha, in addition to providing the best growth and yield responses, also provided the best fertiliser application return (149.77%), and was thus recommended for the experimental region.
