This study investigated the effects of vermicompost fertilization with complementary microbial nutrition on plant growth, yield, and fruit quality organically grown strawberry “Monterey” cultivar. Along vermicompost, five different fertilizers containing plant-growth-promoting rhizobacteria (PGPR) arbuscular mycorrhizal fungi (AMF) were used as nutrition. Here, we examined growth parameters, we...

sulfur (s) is an essential macronutrient influencing plant growth, nutrient efficiency, quality and health of agricultural crops. the purpose of this research was to study the effects of s rates and sources on growth and fruit quality of apple (malus domestica l.) trees of ‘golden delicious’ at west azerbaijan, iran. experiment was conducted during four seasons (2003-2007), using a factorial ra...

The purpose of this study was to investigate the response of physicochemical properties of gerbera (Gerbera Jamesonii L.) to silica nanoparticles (Nanoparticle-SiO2) and calcium chelate (Ca-Chelate) in nutrient solutions. A factorial experiment based on completely randomized design with two factors was conducted in four replicates. The first factor the concentration of Nanoparticle-SiO2 in nutr...

Nitrapyrin (Nt) at 10 ppm, compared to water control, added to a soil-sand-peat medium decreased shoot growth of tomatoes (Lycopersicon esculentum Mill. cv. Marglobe) grown with NOJ-N nutrition but had no effect on growth with NH.-N nutrition. While plant water stress was decreased by NI compared to the control with NOJ-N nutrition, the toxic effect of increased uncombined NH. concentration in ...

The critical nitrogen (N) dilution curve is a suitable analytical tool for in-season estimation of N status to implement precision N management. This study was undertaken for a comprehensive comparison of N dilution curves in Japonica and Indica rice to investigate, whether a single curve can be used for both rice ecotypes and to determine the most robust plant index for assessing N status in r...

The soils of tropical tasar plantation fields in general are sloppy and are primarily deficient of nutrition due to top soil erosion and constant leaf productivity exploitation to rear tasar silk insect, Antheraea mylitta Drury. The rainfed field of Terminalia tomentosa (W&A) plantation has been evaluated for soil fortification with green mulching through legumes, Sun hemp (Crotalaria juncea), ...

Air humidity indicated as vapour pressure deficit (VPD) is directly related to transpiration and stomatal function of plants. We studied the effects of VPD and nitrogen (N) supply on leaf metabolites, plant growth, and mineral nutrition with young micropropagated silver birches (Betula pendula Roth.) in a growth chamber experiment. Plants that were grown under low VPD for 26 d had higher biomas...

Soybean (Glycine max L. Merr.) germplasm, isogenic except for loci controlling male sterility (ms(1)), was utilized to study the effects of reproductive development on certain aspects of photosynthesis. Plants were sampled at various times between flowering (77 days after transplanting) and maturity (147 days after transplanting). During that period photosynthetic rates declined more rapidly in...
