“…Further, the low vigor of the control (non-fertilized) plants could be explained by the poor nutrient content of their natural substrate. Similar observations have already been reported by Moké et al (2013) and Namoi et al (2014).…”

Cucumber (Cucumis sativus L.) is a plant of great importance for food, agriculture, economy and medicine. This importance explains its high demand, intensified by its cultivation conditions, particularly the growing rarity of fertile land and available water. To contribute to this species yield optimization, the effects of fertilizers type [chemical: NPK (12-22-22) and organic: Agribionate] and a control (C) combined to two watering modes (traditional sprinkler and bottle drip) on plants growth and yield have been studied from sowing to harvest. Plant growth (stem length and diameter at the collar, number of leaves and flowers per plant, leaf area) and yield (fruit weight, diameter and length, yield) were assessed. ANOVA2 tests revealed that fertilization (NPK and agribionate) favored plant growth (respectively 34.20 and 37.32 cm in height against 6.67 cm) and increased yield (7498, 66 and 6600.46 Kg/ha against 1558 Kg/ha) with the largest and heaviest fruits (145.69 and 142.80 g) compared to the control (C) that produced the smallest ones (59.35 g). About watering, the bottle drip mode was more beneficial than traditional sprinkler one for cucumber organ growth and plant yield. The interaction (fertilizer type × watering mode) indicated that the best results were obtained with the Agribionate fertilizer watered with the bottle drip method.

“…The intensification effort of crop-based agriculture in every corner of the world has been followed by an increase in the use of chemical fertilizer (Morris et al 2007). However, the consequence of this fertilizer use must be understood to take corrective measure for the sustainable production of crops in Africa in general and in Zambia in particular.…”

“…As a result, per capita food production is declining in Africa, mainly in SSA, while it is increasing in the other world (Bationo et al 2011). Because of this, the long term agricultural productivity in the continent is under threat as crop harvest suffer from continuous soil nutrient mining (Namoi et al 2014).…”

Soil fertility status of cassava fields treated by integrated application of manure and NPK fertilizer in Zambia

Background: Cassava is a heavy feeder crop that can cause serious depletion to soil nutrient stocks. This research aimed to explore soil fertility status and nutrient supply capacity at different growth stages of cassava fields under combined application of organic manure and NPK fertilizers in two agroecologies of Zambia. Topsoil (0-20 cm) samples were collected from cassava fields treated with factorial combination of four levels of chicken manure (0, 1.4, 2.8, and 4.2 ton ha −1 ) and four levels of NPK (control, 50N-11P-41.5K, 100N-22P-83K, and 150N-33P-124.5P). The soils were sampled under the cassava canopy to determine soil pH, available phosphorus (AP), total nitrogen (TN), organic carbon (OC), cation exchange capacity (CEC), exchangeable bases and micronutrients (Fe, Cu, Mn, and Zn). The samples were collected before planting andafter establishment at 4, 8, and 12 months after planting (MAP). Results:Manure application significantly (p < 0.05) increased soil pH, while the application of mineral fertilizer reduced soil pH at all the plant growth stages. Similarly, manure application and their interaction with mineral fertilizer increased OC and TN levels, especially at harvest. By contrast, OC and TN decreased with the application of mineral fertilizer. AP levels increased following the application of both fertilizers. In addition, manure application significantly increased soil Zn content from 0.69 mg kg −1 in the control to 3.54 mg kg −1 for the highest level of manure at harvest. The interaction between manure and NPK significantly affected Fe and Mn content in the soil. Conclusion:The results revealed that sole chicken manure application or its combination with mineral fertilizer improves soil nutrient status of cassava fields in Zambian condition. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

“…Cependant, l'apport au sol des fertilisants organiques et minéral, a stimulé la croissance végétative des plants de maïs et a eu des effets sur le rendement. Ainsi, nos observations rejoignent celles de Olabode et al (2007), Muyayabantu et al (2012a et b), Moke et al (2013), et Namoi et al (2014 (Orwa et al, 2009 ;Muyayabantu, 2010 ;Jeptoo et al, 2013) dans leurs études. Le niveau de fertilité du sol atteint, suite aux apports des biomasses végétales est en corrélation avec le rendement du maïs.…”

“…Dans la zone d'étude, Province de Lomami, son rendement en culture traditionnelle est encore largement inférieur à 800 kg/ha (Mukendi et al, 2017). Les raisons majeures de cette faible production sont nombreuses dont entre autres la faible maîtrise de nouvelles méthodes de productions agricoles et l'usage des pratiques de production non soutenable (Namoi et al, 2014) mais aussi le déclin de fertilité du sol (Ngome et al, 2012). Savini et al (2006) pensent qu'en Afrique 88 % des sols sont déficients en phosphore, ce qui permet l'obtention de rendement faible.…”

R. M. TSHIBINGU et al. / Int. J. Biol. Chem. Sci. 11(2): 816-827, 2017 817 Improvement of soil degraded by inorganic fertilizer, organic matter and yield evaluation of maize (Zea mays L.) in Lomami province, Democratic Republic of Congo ABSTRACTThe study was carried out in Kabinda on a degraded soil that has received inputs from organic and mineral fertilizers in order to assess their effects on maize growth and production. The experiment was conducted during two crop years, season A and season B. Five treatments in four replicates consisted of one control (T0), four levels of fertilizer (inorganic and organic matter) supply: Entada abyssinica (T1), Tithonia diversifolia (T2) Sena floribunda (T3), and Diammonophosphate DAP (T4) were evaluated using a randomized complete block system (RCBD). The observations had related to the parameters of growth and production that underwent the analysis of variance (ANOVA) at 5% level of significance. The results obtained indicate that maize responded positively in the growth stage under the effect of fertilizing indiscriminately of their nature (p <0.05) compared with the control in the two growing seasons. The fertilizers accelerated vegetative growth and increased the yield from 40 to 80% of maize compared with the control of the cropping season indiscriminately. T. diversifolia gave higher seed yield 1398.1 kg / ha and control had lower seed yield 885.5 kg / ha in season A whereas in season B, DAP produced higher seed yield 3332.8 kg / ha and the control plot gave lower seed yield 1825.kg / ha. These organic fertilizers based on E. Abyssinica, T. diversifolia, and S. floribunda were noted for their high yield scores in season A and a non-significant difference in inorganic treatment in season B. These species can be considered as significant sources of soil fertilizer to improve maize yield.
