Efforts were made to obtain forage cultivars with high production capacity and quality and to determine the ideal time to start animal grazing, respecting the morphological characteristics of the grasses. For this purpose, the nutritional value, digestibility and characteristics of the forage canopy of Aries and Aruana (Megathyrsus maximus (Jacq.) or Panicum maximum) cultivars kept under rotational stocking with sheep were evaluated and the management height was determined based on 95% light interception (LI). The experiment was evaluated with repeated measures over time (grazing cycles by season, in 2 years) with a treatment factor (grass cultivar) in a completely randomized block design with eight replicates, using 800 m2 paddocks. The height of the forage canopy before grazing (pre-grazing) determined by 95% LI stabilized around 29 cm. The highest proportion of Aruana leaf blades was observed in winter. Aries grass presented similar leaf blade percentages in summer, autumn and spring. Similar forage accumulation (FA) was observed for both cultivars, decreasing in spring, autumn and winter. Higher crude protein and in vitro dry matter digestibility (IVDMD) were seen in Aries grass, while Aruana grass presented higher neutral and acid detergent fibre and cellulose and lower IVDMD. The nutritional quality of the grasses was maintained throughout the year. The height of the forage canopy of Aries and Aruana recommended for entry into the paddock is 29 cm to maintain nutritional quality. The successful management strategy adopted for grasses combined with nitrogen fertilization provided a greater forage mass quality.

Common lands, being a significant form of natural resource endowment in many developing countries, play a vital role in maintaining the ecological balance, and more particularly in supporting the people, especially the rural poor, in eking out their livelihood. However, the contributions of common lands to the rural economy and ecology have remained unappreciated which has led to the depletion and degradation of these lands. In an attempt to examine the nature and extent of contribution of common lands to household economies, 432 sample households from eight sample villages across four ecological regions in Haryana, northwest India, were surveyed using a structured questionnaire during 1995. We found that common lands still hold an important place in the household economy of rural people of this state. A significant proportion of the sample households obtained substantial biomass resources, income and employment from common lands. The contributions of these lands in terms of variety and extent were many times higher in the households belonging to less developed than developed regions, and those households belonging to poor than wealthy classes. Hence, there is an immediate need to develop effective strategies for the regeneration and sustainable use and management of common lands.
