Effects of Nitrogen Fertilizers on the Growth and Nitrate Content of Lettuce (Lactuca sativa L.)
Nitrogen is an essential element for plant growth and development; however, due to environmental pollution, high nitrate concentrations accumulate in the edible parts of these leafy vegetables, particularly if excessive nitrogen fertilizer has been applied. Consuming these crops can harm human health; thus, developing a suitable strategy for the agricultural application of nitrogen fertilizer i...
متن کاملGrowth and Yield of Lettuce (Lactuca sativa L.) At Abakaliki Agro-Ecological Zone of Southeastern Nigeria
Studies were carried out in 2005 and 2006 raing seasons at four locations (Abakaliki, Ezzamgbo, Ikwo and Okposi) within the Abakaliki Agro-ecological zone of southeastern Nigeria, to determine their suitability for the production of lettuce. The measurements included weather elements, soil physico-chemical propertiesand crop growth and yield. The data collected were subjected to statistical ana...
متن کاملnutrients content and yield in selected cultivars of leaf lettuce ( Lactuca sativa l . var . crispa )
Five cultivars of leaf lettuce (Lactuca sativa L. var. crispa) – Bergamo, Dubáček, Frisby, Lollo Rossa and Redin – were evaluated in two-year experiments carried out at the Faculty of Horticulture in Lednice (Mendel University of Agriculture and Forestry in Brno). Experiments were conducted in two trial years, 1998 and 1999; the lettuce was cultivated in three seasons: spring, summer and autumn...
متن کاملEffect of Nitrogen and Plant Spacing on Nutrients Uptake,Yield and Growth of Tuberose (Polianthes tuberosa L.)
Plant spacing and nitrogen are the most important factors for increasing tuberose quality and quantity. In this study, field experiment carried out as factorial Randomized Completely Block Design (RCBD) in 3 replications. Different levels of nitrogen (0, 50, 100, 150, 200, 250 kg/ha) of ammonium nitrate was used. Second factor was different plant spaces (10, 15, 20 and 25 cm). Results showed th...
متن کاملThe nitrogen and nitrate economy of butterhead lettuce (Lactuca sativa var capitata L).
Quantifying and simulating the relationships between crop growth, total-nitrogen (total-N) and nitrate-N (NO3--N) concentration can improve crop nutritional husbandry. In this study, the relationship between shoot relative growth rate (RGR) and shoot total-N, organic-N and NO3--N concentration of hydroponically-grown lettuce (Lactuca sativa var. capitata L. cv. Kennedy) was described and simula...
