The effect of different nitrogen (N) treatments on the nutrient contents of tomato (Lycopersicon esculentum Mill., cv. ‘Tayfun F1’) under different boron (B) concentrations were investigated in greenhouse conditions with four replications. Four different levels of B (0, 5, 10 and 20 mg kg–1) and three levels of N (100, 200, 300 mg kg–1) were used in this research. The results showed that tomato plant growth was negatively affected with increasing B concentrations and symptoms of boron toxicity were observed. The tomato leaf nutrient concentrations were increased in all plants with B and N treatments and 20 mg kg–1 B and 300 mg kg–1 N treatments were determined to be more effective compared to the others. 20 mg kg–1 B and 100 mg kg–1 N treatment caused the highest micro element concentrations of tomato leaf. This could be interpreted as N application having a dilution effect to be able to maintain development under conditions of toxicity of B. The plants growth under boron toxicity conditions showed increased vegetation with increasing N applications which was attributed to the dilution effect.

UV-B radiation effects on nutrient concentrations in above-ground organs of maize were investigated at silking and maturity at different levels of applied nitrogen under field conditions. The experiment simulated a 20% stratospheric ozone depletion over Portugal. At silking, UV-B increased N, K, Ca, and Zn concentrations, whereas at maturity Ca, Mg, Zn, and Cu increased and N, P and Mn decreased in some plant organs. Generally, at maturity, N, Ca, Cu, and Mn were lower, while P, K, and Zn concentrations in stems and nitrogen-use efficiency (NUE) were higher in N-starved plants. UV-B and N effects on shoot dry biomass were more pronounced than on nutrient concentrations. Nutrient uptake decreased under high UV-B and increased with increasing N application, mainly at maturity harvest. Significant interactions UV-B x N were observed for NUE and for concentration and mass of some elements. For instance, under enhanced UV-B, N, Cu, Zn, and Mn concentrations decreased in leaves, except on N-stressed plants, whereas they were less affected by N nutrition. In order to minimize nutritional, economical, and environmental negative consequences, fertiliser recommendations based on element concentration or yield goals may need to be adjusted.

Abstract Vegetative tissue analyses might help to diagnose nutritional status of a crop. Foliage diagnosis is an effective method to set up balanced fertilization procedures. The current work aims to evaluate nutrient contents of two gerbera leaf sampling periods as a cut flower cultivated in pots with different doses of nitrogen (N) and calcium (Ca) under greenhouse conditions. The experiment was carried out in a protected environment, shelter type, in a container containing substrate in a 3x3+1 factorial scheme. Three doses of N (0.07, 0.15 or 0.2 g L-1) or three doses of Ca (0.02, 0.03 or 0.04 g L-1) were applied every 15 days. Control plants did receive neither N nor Ca. The substrate was analyzed before and after cultivation, and at the end of production years, as well as completely expanded leaves were collected for nutrient analyses. There was not significant interaction between N and Ca doses. Regarding the sampling period or doses of N and Ca, the determined macronutrient concentrations were in the following order of N>K>Ca>P>S>Mg. The micronutrient concentrations were in the following order of Fe>Mn>B>Zn>Cu. Except for K, all the other nutrient concentrations were in the recommended range for gerberas production.

An experiment was conducted at the Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, Bangladesh to evaluate the influence of fertilizer-N on biochemical characteristics, nutrient accumulation and yield of potatoes during the period from November 2002 to March 2003. Two varieties, namely Cardinal and Diamant and five levels of N viz. 0, 100, 125, 150 and 175 kg ha-1 were applied in a factorial randomized complete block design with three replications. The results indicated that the biochemical characteristics, nutrient concentrations, yield components and yield were significantly influenced by the different levels of N. The nitrate reductase activity, chlorophyll content, total free amino acid showed positive linear relationship with different doses of N-fertilizers. The highest tuber weight and nitrogen accumulation were found from the plants which received 150 kg N ha-1. Application of 150 kg N ha-1 resulted in best biochemical characteristics, nutrient uptake, yield and yield components of potato varieties- Cardinal and Diament.

A pot culture experiment was conducted at the Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur during kharif II, 2012 to evaluate the nodulation, biological nitrogen fixation and yield potential of genotypes of mungbean under varying levels of N application. There were 10 mungbean genotypes viz. IPSA 12, GK 27, IPSA 3, IPSA 5, ACC12890055, GK 63, ACC12890053, BU mug 4, BARI Mung 6 and Binamoog 5, each genotype treated with six levels of N (0, 20, 40, 60, 80 and 100 kg N ha-1) . Among the genotypes, the IPSA 12 at 40 kg N ha-1 produced the maximum number of nodules (14.54 plant-1) as well as the highest nitrogen fixation (2.684 mmol C2H4). This resulted in the highest seed yield (14.22 g plant-1). The genotype ACC12890053 recorded the lowest nodulation (6 plant-1), nitrogen fixation (1.134) and seed yield (7.33 g plant-1).Bangladesh J.

Improved Model

An improved model for estimating nutrient contents of the commercial portion of tree boles was developed for four boreal tree species (Populus tremuloides Michx., Betula papyrifera Marsh., Picea glauca (Moench) Voss, and Abies balsamea (L.) Mill.). This model considers the spatial pattern of variation of nutrient concentrations inside the bole and its relationships with tree size. For all species-nutrient combinations, no significant pattern was found for vertical variations in nutrient concentrations, while two types of nonlinear models, using distance from the tree periphery as the independent variable, fit the pattern of horizontal (or radial) variations. These patterns of variability were used to estimate the global nutrient concentration of the bole by using mathematical integration. The values obtained with this method were generally lower, especially for large stems, than values obtained with traditional methods that do not consider the variability of nutrient concentrations inside the bole. This improved model would permit better estimates of the amounts of nutrients lost in biomass upon forest harvesting, as well as internal cycling of nutrients within the bole.

Mineral nutrient uptake of Hydrangea macrophylla ‘Merritt’s Supreme’ affected by nitrogen (N) fertilization rate, container type, and irrigation frequency was investigated. Rooted liners of hydrangea plants were fertilized twice weekly with a N-free fertilizer plus five N rates including 0, 5, 10, 15, or 20 mM N from ammonium nitrate (NH4NO3), irrigated once or twice daily with the same total irrigation volume, and grown in two types of one-gallon containers: a black plastic container and a biodegradable container (biocontainer), made from recycled paper. Concentrations of calcium (Ca) and magnesium (Mg) averaged in the entire plant, and iron (Fe) and manganese (Mn) in roots had increasing trends with increasing N rate. By comparison, increasing N rate had a dilution effect on root phosphorus (P), stem and root potassium (K), stem Ca and Mg, and leaf boron (B) concentrations. In general, nutrient content of each tested element increased with increasing N rate in each structure, or total in the plant. When there was a significant container type effect, plastic containers consistently had increased nutrient concentrations and content compared to biocontainers. One irrigation per day was beneficial in increasing nutrient concentrations of P, Ca, and zinc (Zn) in different plant structures.

An experiment was conducted to determine the effect of different levels of black point infection caused by Bipolaris sorokiniana and other fungal pathogens on some quality characters of wheat grain. Wheat grains were graded on a 0-5 scale based on levels of black point infection. Quality characters of grain viz., protein, fat, dry matter, ash and mineral contents under different grades were determined following standard methods. The dry matter and ash contents of grain decreased while the contents of protein and fat increased with the increasing severity of black point infection. The observations on macro and micro nutrient contents of grain indicated that the amount of nitrogen, phosphorus, calcium, magnesium, sulphur, and boron increased, whereas the contents of potassium, iron, zinc, copper and sodium decreased with the increase of black point infection. However, the reductions in copper content of black point affected grains under different grades of infection were not significant as compared to apparently healthy grains.

The aim of this study was to evaluate the morphogenic, structural, and productive characteristics of Cenchrus ciliaris L. in response to different doses of biofertilizers that originate from the anaerobic biodigestion of goat and sheep fecal matter on Yellow Argisoil. The experiment was performed in a greenhouse, in a completely randomized factorial design using two types of biofertilizers and five dosages (0%, 2.5%, 5.0%, 7.5%, and 10% of soil volume), with four repeats, for the duration of two vegetative cycles. In the first cycle, there was an increase in leaf lifespan and leaf/stem ratio with the use of 10% and 7.5% caprine biofertilizer, respectively. From the second cycle, doses of biofertilizers between 7.5% and 10% led to an improvement in the development of the morphogenic variables - leaf sprouting rate, leaf and pseudostem elongation rate, leaf lifespan, and senescence, as well as the structural characteristics - expanded leaf length and width, number of sprouting, expanded and live leaves, and expanded/expanding leaf ratio, resulting in a 73% increase in biomass. It was concluded that the use of biofertilizers improves the main morphogenic and structural characteristics of Cenchrus ciliaris L., resulting in increased fodder mass yield.
