To study the effect of Zn and B as foliar spray on growth and yield of sweet orange, cv. Blood red at Dargai, Malakand Agency, Pakistan during 2006 and 2007. The micronutrients zinc (Zn) in the form of zinc sulphate (ZnSo4.7H2O) as zinc source at the rate of 0.5 % and 1.0 % and boron (B) in the form of boric acid (H3BO3) at the rate of 0.02 % and 0.04 % were applied as foliar spray at three dif...

High temperature stress at reproductive stages of cotton crop severely affects the yield and quality under changing climatic conditions. To alleviate adverse effects high on crop, regulatory potassium (K), zinc (Zn), boron (B) were assessed by applying different regimes three field glass house Cotton plants subjected to low (32/20 °C ± 2), medium (38/24 (45/30 2) temperatures glasshouse, but so...

Both phenotypic plasticity and local adaptation may allow widely distributed plant species to either acclimate or adapt to environmental heterogeneity. Given the typically low genetic variation of clonal plants across their habitats, phenotypic plasticity may be the primary adaptive strategy allowing them to thrive across a wide range of habitats. In this study, the mechanism supporting the wid...

Our previous work demonstrated that boron (B) supplied to soybeans (Glycine max [L.] Merrill cv ;Williams 82') by a stem infusion technique increased the number of pods on branches and led to a significant yield increase. Therefore, research was continued to determine whether soil or foliar applications of B could be used to achieve the same results. Field experiments were completed with both s...

BACKGROUND AND AIMS Mite domatia are small structures on the underside of plant leaves that provide homes for predacious or fungivorous mites. In turn, mites inhabiting domatia defend the plant by consuming leaf herbivores and pathogens, which can result in a domatia-mediated, plant-mite defence mutualism. Several recent studies have suggested that plants receive enhanced benefits when they pro...

Assessment and management of ecosystem biomass accumulation typically involves extensive field data collection, which includes parameters such as foliar area, stem diameter, woody biomass measurement, etc. The acquisition of these data can be expensive and time consuming, while leaving the user with relatively crude values for modeling intricate dependent variables, e.g., woody and foliar bioma...

A field experiment was conducted during Rabi season of 2012-13 at Regional Agricultural Research Station, Lam, Guntur, with an aim to find out the effect of foliar nutrition on water potential, photosynthetic rate, dry matter production and yield of mung bean under receding soil moisture conditions in split plot design with irrigation and no irrigation as main treatments and foliar sprays as su...

Negative population feedbacks mediated by natural enemies can promote species coexistence at the community scale through disproportionate mortality of numerically dominant (common) tree species. Simultaneously, associations with arbuscular mycorrhizal fungi (AMF) can result in positive effects on tree populations. Coupling data on seedling foliar damage from herbivores and pathogens and DNA seq...

Abstract Plant root nutrient acquisition, and to a lesser extent foliar uptake, maintain plant metabolism strongly regulate terrestrial biogeochemistry carbon-climate feedbacks. However, biogeochemical models differ in their representations of leading significantly different, uncertain, carbon cycle future climate projections. Here we first review principles observations relevant three essentia...

Iron deficiency in plants is caused by a low availability of iron in the soil, and its main visual symptom is leaf yellowing due to a decrease in chlorophyll content, along with a reduction in plant growth and fruit quality. Foliar sprays with Fe compounds are an economic alternative to the treatment with expensive synthetic Fe-chelates applied to the soil, although the efficacy of foliar treat...
