Effets de doses croissantes des composts de fumiers de poules sur le rendement de chou de Chine (<i>Brassica chinensis</i> L.) installé sur un sol acide de Lubumbashi

Abstract

Effects of increasing doses of compost on the performance of Chinese cabbage (Brassica chinensis L.) installed on an acid soil of Lubumbashi Objective: A study was conducted on a ferralsol to assess the agronomic efficiency of manure from chickens and mineral fertilizers (NPK and urea) on the yield of Chinese cabbage. Methodology and Results: The experimental design was a completely randomized with six repetitions and six treatments: T0 (unfertilized control), T1 (175 kg NPK +87 kg urea per hectare), T2 (350 kg NPK+47.5 kg Urea per hectare), T3 (15 t.ha-1 manure of chicken compost), T4 (30 t.ha-1 manure of chicken compost), T5 (60 t.ha-1 manure of chicken compost). Manure of chicken, NPK and urea were incorporated into the soil, respectively, a week before the day of transplantation and 3 weeks after transplantation. Highly significant differences (p < 0.05) were found between treatments in terms of growth and yield of Chinese cabbage corn with yields ranging from 1.4 to 5.1 t.ha-1 , the treatments T2 and T5 which gave similar yields and the highest and lowest T0 treatment. Conclusion and application: With reference to yields and agronomic efficiency, doses of manure at 15 t.ha-1 agree to address any use of mineral inputs. However, due to the low availability of manure nutrients, a mineral fertilizer supplement is recommended. The study showed that chicken manure under the conditions of this trial was a great potential for improving the availability of nutrients in soil and was able to provide the amount of nutrients needed to growing Chinese cabbage without the addition of mineral fertilizers.

Does a Specific Location of Composted Poultry Litter in Soil Influence Nutrient Use Efficiency and Vegetable Production? A Mesocosm Experiment

“…The positive impact of CPL was also shown by Essehi et al (2016) on rubber seedling growth, by Iren et al (2015) on water-leaf growth and yield. Kimuni et al (2014) found that cabbage yield obtained with 60 t ha -1 of CPL was similar to that with 350 kg ha -1 of mineral fertilizers (NPK and urea).…”

“…The better soil aeration at surface which is favorable to nutrient assimilation by roots (Huber & Schaub, 2011) could also explain the higher agronomic efficiency of CPL in CS compared to CB. Lower mineralization rate of CPL incorporated into soil as reported by Kimuni et al (2014) could also be explanatory. Therefore, it could be stated that soil surface is the right place for CPL application in cucumber cropping owing to a maximized effectiveness in nutrient use (Fixen & Garcia, 2006).…”

Effect of the Organic and NPK Fertilizers on the Growth and Yield of Sweet Potato (Ipomoea batatas (L) Lam) in the Centre of Côte d’Ivoire

“…For example, the 200 kg.ha -1 dose of NPK 12-22-22 recorded the best average weights and yields compared to NPK 300, 400 and 500 kg.ha -1 . In fact, for any fertiliser added, the efficiency coefficient of fertilisers for different treatments decreases with increasing doses [32]. These results show the interest and need in low availability of mineral fertilizers to use low doses.…”

Soil Chemistry and Cucumber (Cucumis sativus L.) Yield as Influenced by 16 Years of Composted Poultry Litter Addition

“…Differently to growth attributes, fresh fruit yield was determined by soil calcium concentration. Although previous works reported on the beneficial impact of compost on crop productivity (Kimuni et al, 2014;Mulaji, 2011), no attention was paid to the determinant nutrient in cucumber growth and fruit production yet. Therefore, our findings deserve consideration.…”
