Demand of food crisis has been accelerated because of rapidly growing world population. Because of food crisis, experts are focusing to ensure food security. In this regard, cereal crops have attained the major attention of agriculturists. Maize is one of the vital cereal crops and is considered significant in economy of Africa and the whole world1. Maize is also utilized as fiber feed for livestock and in poultry feed2. In Nigeria, maize is extensively cultivated in forest zones but; large scale production has shifted to the savanna zone with maximum output. Unfortunately, yields of this significant crop are near to the ground because of soil infertility, pests, pathogens and drought.
To boost up yield of corn and elevate economy some alternative nutritional elements should be focused. Accordingly, Silicon is the bioactive and advantageous element and has the nutritional significance regarding plant health3,4. Silicon is highly abundant in soil and present in all organisms. Silicon plays crucial role in development of plants which includes amelioration or complete defense against biological stresses5. Therefore, various are experiments are being performed to check potential of silicon to enhance quality and yield of agricultural commodities.
M.O. Ononyume and colleagues conducted a research to evaluate the impacts of various silicon concentrations (0, 2500, 5000 and 7500 mg, with 0 mg as control) on the growth parameters, yield and vigour of four varieties of Z. mays L. (91 SUWANI, TZL COMP 4, DT STR Y SYN 2 and IWO SYN C2). Scientists planted the feasible seeds in 64 polythene bags consisting of soil and randomized complete block design (a 4×4 factorial experiment) with four replications were used. Moreover, researchers also calculated the plant height, stem girth, leaf area and leaf number at 4, 6, 8 and 10 weeks after planting.
Scientists noted improvement in growth and yield of maize by its cultivation with exogenously applied silicon. Experiment showed that silicon at 5000-250 mg kg–1 of soil should be added by peasants as foundation manure to maximize the performance of maize. However, through investigation is needed to explore alternate techniques to make sure the food security.
