Using UAV Mounted LiDAR to Estimate Plant Height and Growth
… thesis, we develop algorithms to estimate crop heights as well as to detect plots infarms. Plant height estimation is needed in precision agriculture to monitor plant health andgrowth cycles. We use a 3D LiDAR mounted on an Unmanned Aerial Vehicle (UAV) anduse the LiDAR data for height and plot …

Plant Height Dynamics and Competition: From Local Interactions to Global Patterns
… widely recognized as a major force influencing plant community structure, with functional traits predicted to mediate competitive interactions between species. Despite theoretical predictions that taller plant species should exert stronger competitive effects on neighbours, plant height …

Studies on Plant Height and Flowering Date and Their Effect on Seed Yield in Determinate Soybeans (Glycine Max)
… of days to flowering (R1) and maturity (R8), and plant height at these two stages; (2) evaluate the relationships among the traits; and (3) study the value of plant height and flowering date in improving seed yield for determinate soybeans. Both experiments were carried out on the Agronomy-Plant …

Effect of Allelic Variation in Rht Loci on Plant Height and Grain Yield of Soft Red Winter Wheat (Triticum aestivum L.)
<p>Plant height in wheat (Triticum aestivum L.) is controlled in large part by two major Rht genes, Rht-B1 and Rht-D1, which pleiotropically impact lodging and grain yield. Prior to the Green Revolution, wheat varieties contained only ‘wild-type’ Rht alleles (Rht-B1a and Rht-D1a) and were tall and …

Performance of spring wheat under summer rainfall winter irrigated conditions in Zambia
… leaf area index, root biomass, peduncle length, plant height, days to heading and days to maturity were recorded for each plot. Intra season and a combined analysis for season 1 and season 2 was carried out. The varieties did not differ significantly in yield, biological yield, 1000- grain …

Genetic variation of heat tolerance and correlation with other agronomic traits in a maize (Zea mays L.) recombinant inbred line population
… especially in West Texas. Heat stress can reduce plant height, kill the leaf tissues, cause abortion of pollen and kernel, and affect the cell activities. The objectives of this study were to determine the genetic variation of leaf firing, chlorophyll fluorescence, plant height, ear height, leaves …

Assessment of Soil, Yield and Yield Contributing Parameters of Potato in Legume Intercropping and Silicon Application in Texas, United States
… among different parameters with yield. The plant height, leaf number, canopy, stem girth, and soil parameters related to yield collected were analyzed using R-studio. The research findings show an increment in yield and yield attributing potato parameters in intercropping compared to …

Componentes de crescimento e produção de três cultivares de soja utilizando diferentes adubações
… Brazil, accounting for nearly half of the area planted in grain country, this growth is attributed to technological advances and techniques appropriate crop management applied by producers. The aim of this study was to evaluate the agronomic characteristics and yield components of three soybean …

Effects of simulated drift of glyphosate, imazethapyr, glufosinate, and imazamox to non-transgenic rice
… CO2-pressurized sprayer. Glyphosate reduced plant height and primary and total crop yield, with the greatest reduction in primary crop yield resulting from glyphosate applied at boot. Primary crop rice seed germination was reduced by glyphosate. Glyphosate reduced ratoon crop rice seed …

Grasshopper species complexes of forage crops in the piedmont region of Virginia
… head feeders was positively correlated with the plant height. Mixed-forb feeders were negatively correlated. Other vegetation properties (grass/forb ratio and percent of ground cover) were themselves highly correlated with plant height, and yielded no patterns that were as strong as those with …

Quantitative Trait Loci Associated with Waterlogging Tolerance in a Soft Red Winter Wheat Mapping Population
… an anaerobic environment which decreases plant growth and grain yield at maturity. Despite the impact of waterlogging on wheat production both globally and in the southeastern U.S., very little is known about the genetic control of waterlogging tolerance in wheat. The objective of this …

Confirming QTL for seed yield from exotic soybean germplasm
… base, has resulted in a very narrow gene pool. Plant introductions (PI) have been used to expand the N.A. genetic base with limited success when conventional breeding methods have been used. Quantitative trait loci (QTL) mapping has been used to identify genetic regions within PIs that could …

Risk assessment of the transfer of imazethapyr herbicide resistance from Clearfield rice to red rice
… extensive variation for agronomic traits such as plant height, panicle length, tillers/plant, seeds/plant, seed set and grain weight. Outcrossing occurred from all Clearfield rice varieties (¡®CL121¡¯, ¡®CL141¡¯ and ¡®CL161¡¯) to red rice. An average outcrossing frequency of 0.163% was observed in …
