Abstract:

A field trial was conducted during 2022 dry season at Tsuburai Farm Area Kano University of Science and Technology, wudil (Lat 11o58’N and Long 8o25’E) and Bayero University (Lat 11o58’N and Long 8o25’E) Teaching and Research Farm both in Sudan Savannah zone of Northern Nigeria to determine the effect of fish guano and exogenous abscissic acid on growth and nutrient composition of vegetable Amaranth under moisture stress and non-stressed conditions. The experiment was arranged in a Split Plot Design (SPD) and replicated three times to evaluate plant height, number of leaves, leaf chlorophyll, seed yield per plot, yield per hectare and proximate composition at 2,4,6,8 and 10 weeks after transplanting. Treatments combination consist of three periods of stress (0,10 and 20days) which formed the main plots and a factorial combination of 3 levels of fish guano (0, 100 and 200kg-1) and abscissic acid concentrations (0 20 and 50µmolL-1) allocated to the sub-plots. Results revealed that application of Fish_ABA provide evidence of significant differences in growth and nutrient characters compared to control for parameters (plant height, number of leaves, leaf chlorophyll, seed yield per plot, and yield per hectare, percentage moisture, ash, protein, fat, carbohydrate, fiber, nitrogen, phenol, P and K. Based on the results of the study, it can therefore recommend that application of Fish_ABA levels 3(50µmolL-1), 5(100kg-1 / 20µmolL-1), 6(100kg-1 / 50µmolL-1) and 9(200kg-1 / 50µmolL-1) at 20 days water stress are good for adaptation at both Wudil and BUK location.
