Evaluation of growth response of Parkia biglobosa (JACQ) under different levels of organic manures

Abstract

An investigation was carried out to evaluate early growth of Parkia biglobosa under different levels of organic manures in the nursery in order to promote its sustained utilization and regeneration. Seeds were sown in the germination bed at the nursery of Department of Forestry and Fisheries of KSUST, Aliero which took average of three days to germinate and at two weeks after germination, seedlings were transplanted into polythene bags (16 × 14 × 12 cm) filled with cow dung, poultry manure and farmyard manure at 40, 70 and 100 g kg–1 of top soil and top soil only was used as control. The experiment was laid in a completely randomized design with nine replications. Data collection commenced two weeks after transplanting and was done fortnightly for 12 weeks on stem height, collar diameter and number of leaves. Biomass was assessed at twelve weeks and the data were analysed using analysis of variance and follow up tests were conducted with Duncan Multiple Range Tests. The result revealed significant effect on all the variables (stem height, collar diameter and number of leaves) assessed, where poultry droppings at 40 g kg–1 and cow dung at 100 g kg–1 gave the highest growth and cow dung was recommended.

Influence of Organic and Organo-Mineral Fertilizers on Growth and Fruit Yield of Eggplant on Acidic Soil

“…The relatively slow growth of the plants in plots that received mineral fertilizer is due to a high rainfall, which caused the two firsts added fertilizer to leach (May, 6 and June, 6) from root zone to deeper soil horizons. For this reason, farmers in Nigeria urged to use of organic fertilizers, such as poultry droppings and cow dung, instead of mineral fertilizers (Mukhtar et al, 2021).…”

Influence of urea fertilizer on early growth of African Rose Wood (Pterocarpus erinaceous Poir.) seedlings in Kaduna State, Northern Nigeria

“…Smiley et al (2004) promulgated a strategy of nitrogen fertilization (liquid or solid) to improve the fertility of the sites through the application of chemical fertilizers. Tree species differed in their manure requirements and preference as such effort must be made to evaluate the appropriate fertilizer preference of any tree species for enhanced growth and development (Mukhtar et al, 2021). Therefore, this research aimed to document the response to urea fertilizer of P. erinaceous seedling for mass propagation for plantation establishment in Northern Nigeria.…”
