An experiment was carried out at the Teaching and Research Farm of the Faculty of Agriculture, Bayero University Kano (12ᵒ 03.53’N; 8ᵒ 06’ E 543 asl) in the 2013 rainy season to determine the effect of foliar application of aqueous leaf extract of tamarind (ALET) on growth, yield and quality of maize. Treatments consisted of four levels of aqueous leaf extract of tamarind solution at 0%, 2% (40ml of extract in 1litre of water), 4% (80ml of extract in 1litre of water), and at 8% (320ml of extract in 1litre of water). The treatments were laid out in a Randomized Complete Block Design (RCBD) with five replications. Nitrogen fertilizers were added in the form of Urea at 30 kg ha-1, while full recommended doses of P and K (60 kg ha-1) were applied in the form of SSP and MOP respectively. Application of ALET was done every 3 days from 3 weeks after sowing until beginning of tasselling. Results showed that application of the ALET had significant effect on the growth, yield and phenology of maize at low fertilizer applications. Application of 8% ALET produced significantly taller plants with more number of leaves and higher grain yield (4222kgha-1) compared to all other applications. Enhanced tasseling, silking and maturity was observed with application of 4 and 8% ALET. Analysis of grains and stover however showed that when 8% ALET was applied, significantly higher tissue nitrogen and phosphorus were produced. In conclusion, ALET could be applied for enhanced maize growth, yield and tissue total N and P content.
