Growth and nutrient uptake of Citrus rootstock varieties as affected poultry manure and NPK fertilizer in Ibadan, Southwestern Nigeria

Background: Nutritional security overrides food security and the present day agriculture focusses more on sustainable and regenerative agriculture in which use of organic inputs assumes prime significance. The search for viable alternatives to the chemical sources of nutrients demands production of the organic nutrient inputs in large quantities. Organic nutrition is expensive on account of the low nutrient contents and large quantum needed and hence unless produced in situ, turn out to be highly expensive. Organic wastes in the form of crop residues are available in plenty in agricultural fields. Tree leaf litter is another biowaste considered as menace under off farm situations. Rapid resource recycling techniques offer immense potential for the safe disposal of the litter and conversion to quality manures. In this background an experiment was conducted to assess the efficacy of litter composts as nitrogen sources in vegetable cow pea (Vigna unguiculata subsp. unguiculata) in terms of the agronomic efficiencies and nutrient uptake. Methods: The field experiment was conducted in College of Agriculture, Vellayani, Thiruvananthapuram, Kerala Agricultural University during December 2018 to March 2019 in randomized block design with three replications. The treatments included the compost of the two tree species litter prepared by composting with different decomposer organisms and additives and enriched with the biofertilizer, PGPR Mix I. Result: The results of the experiment revealed the highest vegetable yields (7.80 t ha-1) in the treatment involving mango leaf litter composted with glyricidia leaves and earthworms on par with Kerala Agricultural University package of practices recommendation for cowpea and it was 2.7 times that in absolute control. The total nutrient uptake was the highest with mango litter co-composted with poultry manure as nutrient input. Agronomy efficiency indices, in terms of nitrogen were significantly superior for the treatments including mango litter composts and hence prove a suitable nutrient input in vegetable cowpea cultivation.

The experiment was carried out at the Field Laboratory, Department of Environmental Science, Bangladesh Agricultural University, Mymensingh during the period of March, 2012 to July, 2012 to evaluate the effect of fertilizer and manure on the growth and yield of Tulsi and Pudina. There were six treatments consisting of control (No fertilizer and manures), cowdung, poultry manure, cowdung+ NPK fertilizer, poultry manure+ NPK fertilizer and Mixed fertilizer. All the treatment significantly influenced most of the growth and yield components of Tulsi and Pudina. The plant height, No. of branch/plant, No. of leaf/plant, Leaf length, 1000- fresh leaf weight and fresh yield were highest where cowdung was applied. All the above parameters were lowest where no manures were applied (control). From these results it was clear that cowdung was the best for soil quality and growth and yield of Tulsi and Pudina medicinal plant.DOI: http://dx.doi.org/10.3329/jesnr.v7i2.22197 J. Environ.

Npk Fertilizer

This study investigated the direct and residual effects of different poultry compost and NPK fertilizer applications on the growth components of drought-tolerant maize (Zea mays L.) in a derived savanna agroecology of southwestern Nigeria. The experiment was laid out in a Randomized Complete Block Design (RCBD) with six treatments, each replicated thrice. The treatments which were applied at planting, consisted of 100% cockerel manure (CM), 100% broiler manure (BM), 100% layers manure (LM), 33.3% cockerel manure + 33.3% Broiler manure + 33.3% Layers manure (CBLM) at 4.50 kg plot-1,inorganic NPK 20-20-10 fertilizer at 0.30 kg plot-1 and zero manure application as control (CT). The apparent efficiency of N recovery (AENR), N and P ear-leaf (NPEL) contents of maize with poultry manures were higher when compared to inorganic NPK fertilizer applications. The highest mean grain yield 1.30 t ha-1 of maize was obtained with BM treatment that had the highest AENR and NPEL values. This however, was not significantly (p > 0.05) different from the mean grain yield obtained with other treatments during the dry season. Comparable but higher mean grain yield, but also not significantly (p > 0.05) different were obtained during the wet season in all the treatments.
