Abstract

Le coût des engrais chimiques augmente et devient inabordable pour les petits exploitants en Afrique.La présente étude visait à évaluer l'impact des stratégies de fertilisation combinées utilisant de l'urée et du fumier animal (fumier de bovins de boucherie et fumier de litière de volaille) sur le rendement en riz et l'absorption des nutriments.Pour cela, une expérience sur le terrain a été réalisée sur un sol sableux de loam dans le système d'irrigation de Chókwè.Nous avons défini sept traitements dans un modèle de bloc complet randomisé (RCBD), à savoir : T0 : pas d'engrais, T1: 100 % d'urée, T2: 100 % de fumier de bovin de boucherie, T3: 100 % de litière de volaille, T4: 50 % d'urée + 50 % de fumier de bovins de boucherie, T5: 50 % d'urée + 50 % de litière de volaille et T6: 40 % d'urée + 30 % de fumier de bovins de boucherie + 30 % de litière de volaille, répliqués quatre fois chacun.Tous les traitements, à l'exception de T0, ont reçu une quantité d'azote (N) équivalente à 100 kgN • ha-1 .Les résultats ont révélé que les grains les plus productifs (425 g • m-2 ), la hauteur de la plante (115 cm), le nombre de tillers (18) et le poids de mille grains (34 g) ont été observés dans les traitements combinant l'urée avec du fumier (T4, T5 et T6) indiquant que l'apport en N Les données obtenues dans cette étude suggèrent qu'une combinaison d'engrais (T6) conduit à des rendements compétitifs et est donc recommandée pour les meilleures pratiques de gestion des sols.

El costo de los fertilizantes químicos está aumentando y se está volviendo inasequible para los pequeños agricultores en África. El presente estudio tuvo como objetivo evaluar el impacto de las estrategias de fertilización combinadas que utilizan urea y estiércol animal (estiércol de ganado vacuno y estiércol de camada de aves de corral) en el rendimiento del arroz y la absorción de nutrientes. Para esto, se llevó a cabo un experimento de campo en un suelo arenoso franco en el Esquema de Riego de Chókwè. Establecimos siete tratamientos en un Diseño de Bloque Completo Aleatorizado (RCBD), a saber: T0: sin fertilizante, T1: 100% urea, T2: 100% estiércol de ganado vacuno, T3: 100% camada de aves de corral, T4: 50% urea + 50% estiércol bovino de carne, T5: 50% urea + 50% arena de aves y T6: 40% urea + 30% estiércol bovino de carne + 30% arena de aves, replicados cuatro veces cada uno. Todos los tratamientos, excepto T0, recibieron una cantidad de nitrógeno (N) equivalente a 100 kgN • ha-1. Los resultados revelaron que el grano de mayor rendimiento (425 g • m-2 ), la altura de la planta (115 cm), el número de crías (18) y el peso de mil granos (34 g) se observaron en los tratamientos que combinaron urea con estiércol (T4, T5 y T6), lo que indica que el suministro de N Los datos obtenidos en este estudio sugieren que una combinación de fertilizantes (T6) conduce a rendimientos competitivos y, por lo tanto, se recomienda para las mejores prácticas de manejo del suelo.

The cost of chemical fertilizers is increasing and becoming unaffordable for smallholders in Africa.The present study aimed to assess the impact of combined fertilization strategies using urea and animal manure (beef cattle manure and poultry litter manure) on rice yield and nutrient uptake.For this, a field experiment was carried out on a loam sandy soil in the Chókwè Irrigation Scheme.We set seven treatments in a Randomized Complete Block Design (RCBD), namely: T0: no fertilizer, T1: 100% urea, T2: 100% beef cattle manure, T3: 100% poultry litter, T4: 50% urea + 50% beef cattle manure, T5: 50% urea + 50% poultry litter and T6: 40% urea + 30% beef cattle manure + 30% poultry litter, replicated four times each.All treatments, except T0, received an amount of nitrogen (N) equivalent to 100 kgN•ha -1 .Results revealed that the highest yield grain (425 g•m -2 ), plant height (115 cm), number of tillers (18) and thousand-grain weight (34g) were observed in treatments combining urea with manure (T4, T5 and T6) indicating that N supply in the mixture (urea + manure) is more efficient than in isolated applications of N (T1, T2 and T3).The data obtained in this study suggest that a combination of fertilizers (T6) lead to competitive yields and is thus recommended for best soil management practices.

تتزايد تكلفة الأسمدة الكيميائية وتصبح غير ميسورة لصغار المزارعين في أفريقيا. تهدف هذه الدراسة إلى تقييم تأثير استراتيجيات التسميد المشتركة باستخدام اليوريا والسماد الحيواني (روث الماشية البقري وسماد فضلات الدواجن) على غلة الأرز وامتصاص المغذيات. لهذا، تم إجراء تجربة ميدانية على تربة رملية طميية في مخطط ري تشوكوي. وضعنا سبعة علاجات في تصميم كتلة كاملة عشوائية (RCBD)، وهي: T0: بدون سماد، T1: 100 ٪ يوريا، T2: 100 ٪ روث الماشية البقري، T3: 100 ٪ فضلات الدواجن، T4: 50 ٪ يوريا + 50 ٪ من روث الماشية البقري، T5: 50 ٪ يوريا + 50 ٪ من فضلات الدواجن و T6: 40 ٪ يوريا + 30 ٪ من روث الماشية البقري + 30 ٪ من فضلات الدواجن، يتم تكرارها أربع مرات لكل منها. جميع العلاجات، باستثناء T0، تلقت كمية من النيتروجين (N) تعادل 100 كجم نيوتن • هكتار -1. وكشفت النتائج أن الحبوب الأعلى إنتاجية (425 جم • م 2 )، وارتفاع النبات (115 سم)، وعدد الحراثات (18) ووزن ألف حبة (34 جم) لوحظت في العلاجات التي تجمع بين اليوريا والسماد (T4 و T5 و T6) مما يشير إلى أن N توريد تشير البيانات التي تم الحصول عليها في هذه الدراسة إلى أن مزيجًا من الأسمدة (T6) يؤدي إلى غلة تنافسية وبالتالي يوصى به لأفضل ممارسات إدارة التربة.
