This study was conducted to evaluate nutrient production of both orchardgrass and several clovers as a green manure in a ‘Niitaka’ pear (Pyrus pyriforia) orchard. The experiment was conducted at diligent farmer in Boseong in Chonnam on March 26 of 2010, and the treatments included; 1) orchard grass (2.0kg/1,000m2), 2) orchard grass (1.0kg/1,000m2)+ladino clover (1.0 kg/1,000m2), 3) orchard grass (1.0kg/1,000m2)+red clover (1.0kg/1,000m2), and 4) orchard grass (1.0kg/1,000m2) +white clover (1.0kg/1,000m2). Lengths of orchardgrass and clovers were greater in July than those of June and September. Seeding of orchardgrass without clovers in June and July increased dry weight of green manure crops compared with the seeding of orchardgrass with clovers, resulting in greater annual total dry weight. Various green manure treatments produced different amounts of total N and P2O5 from each raw materials and did not satisfy amounts of those nutrients for proper annual growth of ten- to twelve-year-old pear tree. Amounts of K2O producing from green manures, however, satisfied for proper growth of the pear trees.
Abstract
This study was conducted to evaluate nutrient production of both orchardgrass and several clovers as a green manure in a ‘Niitaka’ pear (Pyrus pyriforia) orchard. The experiment was conducted at diligent farmer in Boseong in Chonnam on March 26 of 2010, and the treatments included; 1) orchard grass (2.0kg/1,000m2), 2) orchard grass (1.0kg/1,000m2)+ladino clover (1.0 kg/1,000m2), 3) orchard grass (1.0kg/1,000m2)+red clover (1.0kg/1,000m2), and 4) orchard grass (1.0kg/1,000m2) +white clover (1.0kg/1,000m2). Lengths of orchardgrass and clovers were greater in July than those of June and September. Seeding of orchardgrass without clovers in June and July increased dry weight of green manure crops compared with the seeding of orchardgrass with clovers, resulting in greater annual total dry weight. Various green manure treatments produced different amounts of total N and P2O5 from each raw materials and did not satisfy amounts of those nutrients for proper annual growth of ten- to twelve-year-old pear tree.
