Growth and yield of lettuce (Lactuca sativa L.) as influence by irrigation frequency and poultry manure in Birnin Kebbi, Northern Guinea Savanna of Nigeria

Abstract

As available water resources and plant nutrients are becoming less by the day, there is a pressing need to give more emphasis to efficient use of irrigation water as well as plant nutrients for maximum economic return and resources sustainability. As such, field experiments were conducted to determine Growth and Yield of Lettuce as Influence by Irrigation frequency and Poultry Manure at Irrigation and Demonstration Farm (lat. 12°27′13″N; long. 4°12′01″E; 197m above sea level), Waziri Umaru Federal Polytechnic Birnin kebbi during 2020/2021 dry season. The aim of the experiment was to study the response of Lettuce to irrigation frequency and poultry manure. Treatments consisted of three (3) Irrigation intervals which are; Daily application of water, 1day interval application of water and 2days interval application of water which denoted as A, B and C; and three (3) levels of nutrients which are; 2tonnes/ha, 3tonnes/ha and 4tonnes/ha denoted as N1, N2, N3 and the untreated control respectively. Treatments were laid out in a Randomized Complete Block Design (RCBD) with three replications. Result revealed that; Daily application of water or One-day interval applications of water are most suitable for Lettuce production in Birnin Kebbi. Similarly, Application of 4t/ha of poultry manure gives greater yield advantage. The result of the research concluded by recommending Daily application of water or One-day interval application of water as well as application of 4t/ha of poultry manure could be adopted for higher yield of Lettuce.
