Different Soils

In two «dehesa» grasslands with different soils, one over slate and the other over granite, studies were carried out toinvestigate the influence that phosphoric fertilization, surface tillage of pastures and oat sowing have on the primaryproduction and its nutritive value, on the index of utilization of raining water, and on the evolution of oat stubble withtime. Additionally, economic studies of the previous results have been carried out. Phosphoric fertilization and superficialtilling of pastures did not have a relevant influence on the primary production. Additionally, in the successive regrowthover oat stubble there was no response to phosphoric fertilization. The production increments with respect tocontrols are related to the preparatory tillage for sowing the oats, and the changes that the vegetation experimented.This effect decreased with time. The dry matter production in the oat treatments was higher than in the pastures, bothin slate and granite soils. In dehesa systems the use of raining water for the production of 1 kg dry matter ha-1 was verylow, and, on the average, 0.278 and 0.588 l m-2 were needed in pastures, but this amount decreased significantly in theoats: 0.059 and 0.110 l m-2 in slates and granites, respectively; with better use of the water in the more fertile soils. Theeconomic response to the oat sowing was about 252 and of 160 euros ha-1 year-1 in slates and granites, but there was noeconomic response to the fertilization and superficial tilling of pastures during the period of the experiment.

Trifolium Michelianum

The effects of salinity and hypoxia on growth, nutritive value, and ion relations were evaluated in 38 species of Trifolium and 3 check legume species (Trifolium fragiferum, Trifolium michelianum, and Medicago sativa) under glasshouse conditions, with the aim of identifying species that may be suitable for saline and/or waterlogged conditions. In the first set of experiments, plants were grown hydroponically at four NaCl concentrations (0, 40, 80, and 160 mm NaCl) and harvested after exposure to these treatments for 4 weeks. NaCl concentrations up to 160 mm reduced dry matter production in most species; however, there were differences in salt tolerance among species, with T. argutum, T. diffusum, T. hybridum, and T. ornithopodioides performing well under the saline conditions (dry matter production was reduced by less than 20%). Concentrations of Na+ and Cl− in the shoots increased with increasing salinity levels, and species again differed in their capacity to limit the uptake of these ions. Dry matter digestibility at 0 mm ranged from 49.8% (T. palaestinum) to 74.0% (T. vesiculosum) and decreased with increasing NaCl concentrations. A second set of experiments evaluated the tolerance of Trifolium species to hypoxic conditions in the glasshouse. Shoot growth, and to a lesser extent root growth, were reduced in all Trifolium species when plants were exposed to stagnant, non-aerated conditions for 28 days, but T. michelianum, T. resupinatum, T. squamosum, T. nigrescens, T. ornithopodioides, T. salmoneum, and T. fragiferum were the least affected species. All species acclimated to the oxygen-depleted conditions by increasing the gas-filled porosity in the roots. This study has provided information that will assist in the identification of forage species for saline and/or waterlogged areas.

Nutrient Changes

This study aimed to determine the increase of dry matter production and Nutrient changes of Indigofera zollingeriana  cultivated in Sapric peat soils with harvest age of  2, 3 and 4 months after pruning. Indigofera foliage was obtained from the existing plot of approximately 3 years old  that grown in the experimental field of the UARDS Laboratory of the Faculty of Agriculture and Animal Sciences of UIN Suska Riau. The research design of  randomized block design (RBD) was apllied consisting of 3 age treatments with 4 group. Each treatment, consisted of indigofera biomass harvested at 2 months old (2M),  3 months old (3M) and  4 months old (4M). The results showed that postponing harvest from 2 months to 4 months significantly (p<0.05) increased dry matter production of 71.97 g to 437.62 g and significantly (p<0.05) decreased crude protein (CP) content from 27.45% to 21.23%. Meanwhile, crude fibre (CF), extract ether (EE), ash and nitrogen free extract (NFE) contents were not influence by postponing harvest from 2 to 4 months.  The respective ranges of CF, EE, ash and NFE content of I. zollingeriana were CF: 15.50%-16.50%, EE: 2.11%-2.85%, ash: 7.55%-8.31% and NFE: 46.39%-51.15%. It can be concluded that the dry matter production of I. zollingeriana that grown on Sapric peat soils were significantly influenced by harvest age.
