Productivity Of Citrullus Lanatus As Affected By Cowdung-Poultry Droppings (COPODS), Spacing And Variety In Gashua, Nigeria

Abstract

This research aimed to examine the influence of varying levels of cow dung-poultry droppings (COPODs) and plant spacing on the growth and yield of different watermelon varieties. Four COPOD levels ([without COPODs], [4t + 1t COPODs], [8t + 2t COPODs], and [12t + 3t COPODs]), four plant spacing options (25, 50, 75, and 100 cm), and four watermelon varieties (Sugar baby, Koalack, Royal sweet, and Paradise) were combined in a factorial experiment to assess their effects on key growth metrics, including vine length, leaf production, fruit weight, and yield. The study found that increasing levels of COPODs and wider plant spacing significantly promoted vine length, leaf production, fruit weight, and overall yield. Among the varieties tested, Koalack demonstrated the most vigorous growth, although differences between varieties were not always statistically significant. While interactions between COPODs, spacing, and variety generally did not produce significantly different outcomes, there were notable interactions between COPODs and spacing, as well as between spacing and variety. These results highlight the importance of organic fertilization and appropriate plant spacing in enhancing the growth and yield of watermelon varieties. The findings suggest that adopting a combination of wider planting distances and adequate applications of COPODs can be a valuable strategy for maximizing watermelon production
