Nitrate leaching is one of the most important pathways of nitrogen (N) loss which leads to groundwater contamination or surface water eutrophication. Clarifying the rates, controlling factors and characteristics of nitrate leaching is the pre-requisite for proposing effective mitigation strategies. We investigated the effects of interactions among chemical N fertilizer, straw and manure applica...

Cultivation of Pleurotus ostreatus on different substrates such as rice straw, rice straw + wheat straw, rice straw+ paper, sugarcane bagasse and sawdust of alder was investigated. All the substrates except rice straw were supplemented with 10% rice bran. The substrate without supplement was considered as control. The effects of various substrates on mycelial growth, colonization time, primordi...

Feeding cum growth trial was conducted on male Barbari goats to study the growth, blood metabolites, antioxidant and coccidial egg count feeding of Maize silage having Moringa leaves. Eighteen (Aged about 3 months Avg B.Wt. 9.53±0.42 kg) were divided in completely randomized design into (CRD) three groups six each. Control group (Gr C) fed with concentrate pellet, green gram straw ad lib. Treat...

Abstract: The aim was to evaluate the effects of previous crop and top-dressing nitrogen fertilization on yield physiological sanitary quality common bean seeds. design used in randomized blocks a split-plot scheme, with four replications. plots were represented by three crops (sole maize, maize + Urochloa ruziziensis sole U. ruziziensis), preceding bean. subplots consisted N doses (urea) appli...

In the EU, pigs must have permanent access to manipulable materials such as straw, rope, wood, etc. Long straw can fulfil this function, but can increase labour requirements for cleaning pens, and result in problems with blocked slatted floors and slurry systems. Chopped straw might be more practical, but what is the effect on pigs' behaviour of using chopped straw instead of long straw? Commer...

Poor housing has always favoured domiciliary Triatominae (R Briceño-León 1990, La casa enferma. Editorial Acta Científica Venezolana, Caracas, Venezuela, 149 p.). In the past, house improvement has been a feature of Brazilian National Control Programmes (RS De Brito 1968, As realizações do Departamento Nacional de Endemias Rurais no campo da profilaxia da doença de Chagas, p. 560-574. In JR Can...
