Performance of poplar (populus deltoides bartr.) and its effect on wheat yield under agroforestry system in irrigated agro-ecosystem, India
The quantitative performance of wheat crop under 1-5 year old poplar plantations in irrigated agro-ecosystem was studied to ascertain the biological yield of tree and crop. Results revealed that growth and yield of wheat decreased significantly with the increase in poplar age. The per cent reduction in net grain yield was 17% under one year old poplar plantation, which increased to 52.15% under...
متن کاملResponses of Populus deltoides × Populus nigra ( Populus × euramericana ) clone I - 214 to high zinc concentrations
• We hypothesized that poplar can be useful for the extraction of zinc (Zn) from contaminated soils and water. However, the physiological response and the base of tolerance of poplar plants to this heavy metal are little known. • Plants of Populus deltoides × P . nigra ( P. × euramericana ) I-214 clone were grown in glasshouse and treated with three different Zn concentrations (1, 100 and 1000 ...
متن کاملFine root dynamics in a developing Populus deltoides plantation.
A closely spaced (1 x 1 m) cottonwood (Populus deltoides Bartr.) plantation was established to evaluate the effects of nutrient availability on fine root dynamics. Slow-release fertilizer (17:6:12 N,P,K plus micronutrients) was applied to 225-m(2) plots at 0, 50, 100 and 200 kg N ha(-1), and plots were monitored for two growing seasons. Fine root production, mortality, live root standing crop a...
متن کاملGrowth and biomass of Populus irrigated with landfill leachate
Resource managers are challenged with waste disposal and leachate produced from its degradation. Poplar (Populus spp.) trees offer an opportunity for ecological leachate disposal as an irrigation source for managed tree systems. Our objective was to irrigate Populus trees with municipal solid waste landfill leachate or fertilized well water (control) (N, P, K) during the 2005 and 2006 growing s...
متن کاملGC-MS analysis of compounds extracted from buds of Populus balsamifera and Populus nigra.
The composition of hexane and ether extracts from buds of two poplar species (Populus balsamifera and P. nigra) was investigated by GC-MS method. In hexane extracts, 54 "neutral" compounds were recorded. The greatest amounts of them are sesquiterpenes and n-alkanes. Among 56 components of ether extracts, many aliphatic acids and hydroxyacids were detected. However, the main fraction consists of...
