Doses of cattle manure and levels of irrigation with wastewater in the cultivation of peppers

Abstract

In areas with water scarcity, recycled water and cow manure in organic substrate makes the cultivation of peppers possible, supplying water and nutrition to pepper. The present research was conducted to evaluate the effect of cattle manure doses and levels of irrigation using wastewater on pepper cultivation (Capsicum frutescens L.). The treatments include: three replacement levels of wastewater treated, based on the need of water culture (NWC): 100% NWC (LI1), 75% NWC (LI2) and 50% NWC (LI3); they were combined with six doses of cattle manure tanned: D1 (0% manure and 100% soil), D2 (10% manure and 90% soil), D3 (20% manure and 80% soil), D4 (30% manure and 70% soil), D5 (40% manure and 60% soil) and D6 (50% manure and 50% soil) based on volume. Growth parameters evaluated were plant height, stem diameter, number of leaves and leaf area, from 45 days after sowing (DAS). At 150 DAS the peppers irrigated with 50% NWC had mean of 40.9 cm (plant height). The increment in 10% of manure showed there is an increase of more than 10% in the average value of the variables studied.
