Abstract
The use of organic manures, constitute
an alternative to that of polluting artificial fertilizers. In this study, the
effect of various levels of hen droppings fertilization on the production of
biomass, chemical composition and carrying capacity of P. clandestinum were
evaluated at the Research and Experimental Farm (REF) and at the Animal
Nutrition and Feeding Laboratory of the University of Dschang, between
April and September 2016. A completely randomized block design comparing three
nitrogen level of fertilization in hen droppings form (0; 100 and 200 kg N/ha)
on 4 m2 plot of P. clandestinum were used. Each treatment was carried out in
four replications for a total of 12 experimental plots. Then a sample of 500 g
of forage has been collected in the center of each plot, then dried and used
for the evaluation of the biomass and the chemical composition of P. clandestinum, according to the level of fertilization
and the cutting frequency. The results showed that the fertilization with the
hen droppings positively influenced (p tion at the
first cutting frequency and the highest value (47.12 cm) was obtained with of
200 kg N/ha rate of fertilization. The biomass of this fodder increased
significantly (p s with
the increasing cutting of frequency whatever the level of fertilization.
Independently of the fertilization and the cutting frequency, the maximum
biomass (6.22 t DM/ha) was obtained with the first cutting at the 200 kg N/ha
of hen droppings fertilization. The fertilization influenced in variable way
the chemical composition of P. clandestinum. The dry matter and organic matter content
decrease with the level of fertilization and the highest values (83.79% and
89.39% respectively for the DM and OM) were obtained on the control plot at the
third and the first cutting. Moreover, the ash and crude protein contents
increased significantly (p
有机肥料的使用构成了污染人工肥料的替代品。在这项研究中,2016年4月至9月,在研究与实验农场(REF)和德昌大学动物营养与饲养实验室评估了不同水平的母鸡粪便施肥对隐尾蠊生物量、化学成分和携带能力的影响。采用完全随机区组设计,比较了在4平方米的P.clandestinum地块上以母鸡粪便形式(0、100和200公斤N/ha)施肥的三种氮水平。每种处理在总共12个实验区的四个重复中进行。然后,在每个地块的中心采集500克饲料样本,然后进行干燥,根据施肥水平和切割频率,用于评估隐尾蠊的生物量和化学成分。结果表明,用母鸡粪便施肥对第一次扦插频率有积极影响,在200 kg N/ha的施肥率下获得最高值(47.12 cm)。无论施肥水平如何,该饲料的生物量都随扦插频率的增加而显著增加(p<0.01)。与施肥和扦插频率无关,在200 kg N/ha的母鸡粪便施肥条件下,第一次扦插的生物量最高(6.22 t DM/ha)。施肥对隐尾藻的化学成分有不同程度的影响。干物质和有机质含量随着施肥水平的降低而降低,在第三次和第一次切割时,对照地块的干物质和无机质含量分别达到83.79%和89.39%。灰分和粗蛋白含量显著增加(p
