Determining the Best Planting Density in Mechanized Transplanting of Rice Compared to Manual Transplanting in Conditions of High Seedling Age
It is important to determine the appropriate planting density in the conditions of using old seedlings of paddy rice. For this purpose, a field experiment was conducted as a randomized complete block design at Qaemshahr, Northern Iran, in four replications and in two years, 2020 and 2021. Plant densities consisted of manual-traditional planting of up to 11 hills/m2 (with unequal planting spaces...
متن کاملEffect of planting depth on growth of open-rooted Pinus elliottii and Pinus taeda seedlings in the United States
Three studies in the Coastal Plain of Georgia were remeasured 7 or 8 years after planting to determine the effects of planting depth on field performance of open-rooted seedlings [root-collar diameter (RCD) ≥ 5 mm]. Average planting depth (i.e. shoot height before planting minus shoot height above ground after planting) for machine planted P. elliottii was 14 cm while hand-planted P. taeda seed...
متن کاملA Consensus Genetic Map for Pinus taeda and Pinus elliottii and Extent of Linkage Disequilibrium in Two Genotype-Phenotype Discovery Populations of Pinus taeda
A consensus genetic map for Pinus taeda (loblolly pine) and Pinus elliottii (slash pine) was constructed by merging three previously published P. taeda maps with a map from a pseudo-backcross between P. elliottii and P. taeda. The consensus map positioned 3856 markers via genotyping of 1251 individuals from four pedigrees. It is the densest linkage map for a conifer to date. Average marker spac...
متن کاملLife Cycle and Cost Benefit Analyses of Ethanol Production from Slash Pine (pinus Elliottii) Plantations
This paper considers potential cellulosic ethanol production from Southern slash pine (Pinus elliottii) plantations. The net energy balance (NEB), emissions and associated environmental impacts, unit cost of ethanol production, and associated changes to forest land values are calculated and preliminary results are given. The NEB is found to be positive at 2.2, meaning that for every unit of ene...
متن کاملOleoresin yield and carbon stocks in tapped subtropical Pinus elliottii forests
Background Low-cost methods to mitigate the increasing levels of carbon dioxide in the atmosphere and their implications on global climate change have received considerable attention in the last years [1,2]. Afforestation is an important alternative to reduce the rise in atmospheric CO2 concentration due to the system’s ability to fix carbon in forest biomass and soil [3]. Several studies have ...
