An experiment designed to assess the effect of two grazing pressures (GP, expressed as kg MS/100 kg LW) and four levels of supplement (0, 0.25, 0.50 and 0.75 expressed as kg/100 kg LW) fed to yearling heifers (212 kg) on live weight gain, was carried out at the Dairy Unit of INIA La Estanzuela (Uruguay). The experiment consisted of 8 treatments. Forty animals were used in the experiment, 5 per ...

Gazal boynuzu (Lotus corniculatus L.); bir dizi abiyotik strese dayanıklılığı nedeniyle bazı sorunlu alanlarda yem üretmek dışında otlak ekosistemlerinin ve doğal yaşamın önemli bileşenidir. yetiştiriciliğinin yaygınlaştırılması için çözümlerden biri, verimliği artıracak uygun yetiştirme yöntemlerini belirlemektir. Bu araştırma, farklı sıra aralığı (20,40,60 80 cm) tohum miktarlarının (0,5, 1,0...

Abstract Phytomanagement techniques using native species allow the recovery of contaminated soils at low cost and circumvent ecological risks associated with use non-native species. In this context, a paradigmatic brownfield megasite highly by As Pb was sampled in order to analyze soil–plant interactions identify plant phytoremediation potential. A survey first carried out 20-ha area obtain an ...

The establishment of a nitrogen-fixing symbiosis is an economically important plant phenomenon. Biological reduction of dinitrogen to ammonia is among the most effective fixation systems facilitating the plant growth in nitrogen starved soils without the requirement of massive inputs of fertilizers. This process occurs in legumes roots in structures called nodules. Nodule development is induced...
