Abstract

Intensive agriculture is a farming system characterized by a lot use of input, causing a harm stress on the environment, as well as high price of inorganic fertilizers discouraged some farmers in Jordan to apply fertilizers to their crops. The objective of this study was to investigate the impact of chicken manure and NPK on growth and yield of sweet pepper (Caspicum annum L.), A greenhouse experiment was conducted at Albalqa applied university research station in Jordan using randomized complete block design (RCBD) replicated four times. Three treatments were used using Randomized Complete Block Design (RCBD) with four replications: control (without fertilizer), chicken manure at the rate of 15 t/ha, and NPK (15:15:30) with trace elements at 100 Kg/ha. We evaluated plant height (cm), leaves number per plant, number of days to 50% flowering, fruit number per plant, fruit length, yield of fruit per plant (kg), and yield of fruit per hectare (t/ha). Treatments showed significant differences between. The NPK treatment gave the highest plant height (cm), leaves number per plant, fruits number per plant, yield of fruits per plant (kg), and yield of fruits per hectare (t/ha).
