Sand abrasion injury and biomass partitioning in cotton seedlings
Wind blown soil particle abrasion negatively impacts millions of hectares of crops annually. The goal of this study was to examine the effects of wind and wind blown sand abrasion damage on cotton (Gossypium hirsutum L.) seedling biomass partitioning to leaves, stems, and roots. Seedlings of three cotton cultivars were exposed to no wind (untreated controls) or sand abrasive flux densities of 0, ...

Shifts in plant nutrient use strategies under secondary forest succession
Abstract In evergreen broad-leaved forests (EBLFs) in Tiantong National Forest Park, Eastern China, we studied the soil chemistry and plant leaf nutrient concentration along a chronosequence of secondary forest succession. Soil total N, P and leaf N, P concentration of the most abundant plant species increased with forest succession. We further examined leaf lifespan, leaf nutrient ...

Corn response to competition: growth alteration vs. yield limiting factors
Competition mechanisms among adjacent plants are not well understood. This study compared corn growth and yield responses to water, N, and shade at 74,500 plants ha–1 (1x) with responses to water and N when planted at 149,000 plant ha–1. Plant biomass, leaf area, chlorophyll content, reflectance, and enzyme expression (transcriptome analysis) were measured at V-12. Grain and stover yields were ...

Leaf Cares Article - Foliar Analysis
What is Leaf tissue testing? Leaf tissue testing is a crucial process for evaluating the concentration of essential elements within plant tissue. Essential nutrients, categorised as micronutrients and macronutrients, play key roles in sustaining the plant’s life cycle. Micronutrients, required in smaller amounts and macronutrients needed in larger amounts are essential for achieving ...

Variation in characteristics and imazamox tolerance of feral rye
Rye (Secale cereale L.) is a minor crop in America, with similarities to wheat (Triticum aestivum L.) in growth habit and distribution. However, feral rye has become a weed in wheat. Little is known about variation in feral rye morphological characteristics that influence success of cultural controls. Thus, 21 feral rye populations were sampled from wheat fields in central Oklahoma to ...

Leaf nitrogen concentration as an indicator of corn nitrogen status
Plant-based measurements can be used to diagnose the in-season N status of corn (Zea mays L.). Our objective was to assess the relationship between the corn nitrogen nutrition index (NNI), an index based on whole plant N concentration, and leaf nitrogen concentration of the uppermost collared leaf expressed on the basis of dry matter (DM; NL) or area (NLA). Three to seven N fertilization ...

Water deficit alters canopy structure but not photosynthesis during the regrowth of Alfalfa
Growth of alfalfa (Medicago sativa L.) following the correction of a water deficit will depend in part on the characteristics of the canopy grown during the water deficit. The current study was undertaken to determine the extent to which canopy structure and photosynthetic capacity are affected in alfalfa plants regrowing following defoliation while exposed to a water deficit. The effects of five ...

Multi-temporal variation in water consumption of summer maize as determined by the Water Transformation Dynamical Processes Experimental Device
A better understanding of the multi-temporal variation in evapotranspiration (ET) at different crop growth stages is the key for determining a reasonable irrigation schedule. In this study, a new device known as ‘Water Transformation Dynamical Processes Experimental Device’ (WTDPED) was used to monitor ET for maize under controlled environmental and groundwater conditions, and the ...

Effects of foliar-applied ethylene inhibitor and synthetic cytokinin on creeping bentgrass to enhance heat tolerance
Heat stress is a major factor causing leaf senescence and other physiological damages in cool-season grass species. Cytokinins and ethylene are two major plant hormones affecting leaf senescence. The objective of this study was to determine whether foliar application of an ethylene synthesis inhibitor (aminoethoxyvinylglycine, AVG) and a synthetic cytokinin (trans-zeatin riboside, t-ZR) would ...

Effect of height on the competitive ability of wheat with oats
Competitive ability of wheat is influenced by a range of attributes such as plant height, tiller number, and light interception. This study focused on the effect of plant height on weed competitiveness of a set of near-isogenic wheat lines (NILs). The set included seven bread wheat (Triticum aestivium L.) and six durum wheat (T. turgidum L.) cultivars, each having a semidwarf and tall ...

Leaf Area - How & Why Measuring Leaf Area is Vital to Plant Research
What is Leaf Area? It is easy to measure leaves, and they are also the parts of a plant most responsive to their environment. The combination of these two factors makes leaf area measurement extremely useful to scientists and growers. Besides, leaves are one of the main plant organs and are responsible for the productivity of a plant, and on a larger scale, of an ecosystem or a farm. Therefore, ...

Yield and plant growth response of peanut to midseason forage harvest
Harvesting of peanut (Arachis hypogaea L.) foliage during the growing season may increase farm revenue through the sale of peanut hay; however, it is unknown how the peanut plant will respond to forage removal with respect to plant characteristics, pod yield, quality, and revenue. This experiment was a randomized complete block design where peanut foliage was harvested or sprayed with a plant ...

Ushering in new age controls for age old pest problems
Our gardens are our wonderlands, oases and refuges - green islands in a sea of concrete, brick, and tar. They act as creative outlets where we can unwind and relax. They are also safe havens, where our kids and pets can let loose. But even though our gardens are far removed from the rolling fields, temperate woods and tropical forests of nature, they are also home to some less loved ...

Comparative plant growth and development in two cotton rotations under irrigated and non-irrigated conditions
Incorporating perennial grasses such as bahiagrass (Paspalum notatum Fluegge) to diversify the conventional two-crop rotation of peanut (Arachis hypogaea L.) and cotton (Gossypium hirsutum L.) prevalent in the U.S. Southeast (SE) is advocated. However, little is reported on growth and development for cotton grown in rotation with perennial grasses. Our objectives were to compare plant ...

Maize morphophysiological responses to intense crowding and low nitrogen availability: an analysis and review
Mounting concerns over the cost and environmental impact of N fertilizer combined with progressively higher plant densities in maize (Zea mays L.) production systems make progress in maize N use efficiency (NUE) and N stress tolerance essential. The primary objectives of this 3-yr field study were to (i) evaluate the N responsiveness, NUE, and N stress tolerance of multiple modern maize genotypes ...

How plants grow and develop
How does a complete plant with stems, leafs and flowers develop from a tiny clump of seemingly identical cells? For a very long time, the mechanism of tissue formation in plants remained unclear. The biochemists from Wageningen University also would not have come up with the answer if it wasn’t for their model building colleagues that simulated plant development with their mathematical ...

Application of two vermicomposts on a Rice crop: Effects on soil biological properties and rice quality and yield
Vermicomposts have been considered as a soil additive to reduce the use of mineral fertilizers because they provide required nutrients, increase cation exchange capacity, and improve water-holding capacity. However, the effect of each vermicompost on soil properties and crop yield depends on its chemical composition. The main objective of this work was to study the effect of incorporating two ...
