An Examination of the Ecological Effects of Pure and Mixed planting on the Production Grasses and the Living Place of Weeds Under the Dry Farming Condition
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2014, Vol 2, Issue 4
Abstract
In order to examine the impact of pure and mixed planting on the production of grasses and also the biological control of weeds an experiment was conducted in the research farm of Alashtar city of Lorestan province between the years 1391 and 1392. This experiment within the design of complete random blocks (RCBD) with 6 protections which included 100:0 (rouph pea pure planting) 0:100 (pure planting of barley) and the 20:80, 40:60, 60:40, 80:20 (rouph pea: barley) mixtures and 3 repetitions was carried out . The experimental rouph pea was considered the local item of the area and the barley item the Sararoud. The results of the experiment showed that the highest turnover of barley dry grasses belongs to three protections of 0:100, 20:80 and 40:60 (rouph pea: barley) in line with what is equal to 3.330 ، 3.143 and 2.690 tons in each hectare and also the most amount of that relating to two protections of 80:20 and 60:40 (rouph pea: barley) was observed as equal to 2.013 and 1.967 tons in each hectare. Also the most amount of rouph pea dry grasses from two protections 60:40 and the pure farming of rouph pea was equal to 1.426 and 1.384 tons in each hectare respectively; and between the three protections of 80:20 , 40:60 and 20:80 from the statistical perspective there was no meaningful difference. The results of this experiment showed that the most number of all of the weeds belongs to two protections relating to the pure farming of barley and rouph pea equal to 28.30 and 20.33 shrub in each square meter respectively. And in all of the ratios of mixed farming the population of weeds was less than the pure planting of the two plants. Also the biggest weight of the general dry of weeds compared to the protection of pure farming of barley was equal to 28.73 grams in each square meter and the least of that was observed in the protections 20:80 40:60 and 100:0 Thus considering the results that were reached from the above experiments it can be said that the mixed system compared to pure farming can be effective in reducing the number of weeds and their non-chemical control and also the production of farm products.
