Evaluation of Different Concentrations And Frequency of Foliar Application of <i>Moringa Extract</i> on Growth & Yield of Onion, <i>Allium cepa</i> Lam

Abstract

Field trials were conducted between 2010/11 and 2011/12 at the Forestry Research Institute of o Nigeria (FRIN) of Federal College of Forestry Mechanization Afaka, Kaduna experimental site, 10 1o 1 03 N, 07 21 E and 644m above sea level in the Northern guinea savanna agro-ecological zone during 2011 to 2012 dry season. The objective was to evaluate the effect of different concentration and frequency of foliar application of Moringa extract on growth and yield of Onion (Allium cepa Lam). Fresh Moringa oleifera shoots were obtained from experimental site of the College when it was 35 days old, air dried for some days and crushed with water (10kg of dry material in water) in a household blender for 10 minute. The solution was filtered through a filter paper (Whattman No 42) and the liquid extracts obtained were diluted with water to produce the treatments. The treatments consisted of four concentration 2% (1 litre of extract/50 litre of water), 4% (1 litre of extract/25 litre of water), 3.2% (litre of extract/31 litre of water), 3.7% (1 litre of extract/27 litre of water) and a control (no extract) and two frequency of foliar application once (3weeks) and twice 3 and 6 weeks after transplanting. The trial was laid in a Randomized Complete Block Design(RCBD) and replicated three times. Data were collected on number of leaves/plant, plant height and crop vigour score at 5, 7 and 9 WAT. The data collected were subjected to analysis of variance. Result obtained showed a significant (P = 0.05) effect of the treatments on the characters measured with moringa extract concentration ratio of 1:2 (50%) and frequency periods of foliar application at 3, and 6 weeks after transplanting manifesting the highest effect. Based on the result, application of Moringa extract concentration ratio of 1:2(50%) and frequency period of foliar application at 3, and 6 weeks after transplanting of onion should be adopted for use in Northern guinea savannah ecological zone on the variety of onion tested, since it is easier to get Moringa all year round and in large quantities for large hectare of farm land.

Performance and Quality of Muskmelon (Cucumis melo L.) as Influenced by Crop Spacing and Rates of Swine Manure Application

“…Moniruzzaman et al (2007) also reported higher seed yield of okra at the narrowest spacing and this also corroborates the findings of Falodun and Ogedegbe (2016) who recorded higher pod yield of okra at narrower spacing compared to wider spacing. The significant increase in some vegetative characters and yield with the 15 t/ha application of swine manure is similar to the work of Curuk et al (2004) who reported increases in fruit yield after high manure input compared to customary inorganic fertilization and this further supports the work of Mohammed et al (2013) who observed an increase in growth and yield of onion applied with moringa extract.…”

Moringa leaf extract as a bio-stimulant on growth, yield and nutritional improvement in cabbage

“…The overall effects of all the growth enhancing components in moringa leaf extract (MLE) have made it a novel and marvelous natural bio-stimulant. Interestingly, many recent scientific reports have highlighted that MLE application to plant can provide beneficial nutrient elements, improve antioxidant defense system and enhance vegetative as well as reproductive growth resulting in higher yield and economic benefits under stressed and non-stressed situations (Abohassan and Abusuwar, 2018;Prabhu et al, 2010;Aluko et al, 2017;Hala et al, 2017;Merwad, 2017;Matthew, 2016;Emongor, 2015;Rady and Mohamed, 2015;Ozobia, 2014;Mohammed et al, 2013;Abdalla, 2013;Mvumi et al, 2012Mvumi et al, , 2013. Vegetables are enriched with different vitamins, minerals, and phytochemicals.…”

Drogas usadas como controles positivos nos ensaios de toxicidade com Allium cepa L.: uma revisão da literatura

“…Por conseguinte, a escolha da espécie de cebola utilizada emerge como uma variável que pode ser manipulada, influenciando nos resultados obtidos (Messias et al, 2021). Além disso, não devemos negligenciar o impacto da variação na concentração da substância, uma vez que essa também se configura como uma variável suscetível de interferir nos desfechos experimentais como é possível identificarnos estudos de (Mohammed et al, 2013;Hidangmayum;Sharma, 2017;Santos et al, 2018).…”
