Quality Response

Abstract Loropetalum chinense (also called Chinese Fringebush or Chinese Witch Hazel) is commonly used in the Florida landscapes. However, in recent years, there have been increasing reports and complaints of unexplained decline throughout Central Florida. The objective of this study was to evaluate the growth and quality response of declining L. chinense plants to foliar micronutrient and miticide applications. L. chinense ‘Ruby’ plants exhibiting significant decline symptoms were treated with eight foliar fertilizer treatments (High Cu, Low Cu, Kocide® 2000 [copper hydroxide], B, Mn, Zn, and Peters S.T.E.M.) and half of the plants also received two treatments of GardenTech Sevin Concentrate Bug Killer® (carbaryl, 22.5% AI). Plant growth was not influenced by miticide or fertilizer treatments. However, plants sprayed with Cu (i.e., Cu high, Cu low, and Kocide) had quality ratings, at 4 and 8 weeks after treatment, that were significantly higher than plants treated with other foliar fertilizers. Additionally, results indicated that there was no fertilizer treatment effect on mite populations. Failure of the miticide to enhance plant quality ratings, suggested that eriophyid mites were not associated with decline symptoms. The quality of declining landscape plantings of L. chinense ‘Ruby’ can be improved with the application of foliar Cu sprays.

The aim of this study was to evaluate the quality of virgin oil pressed from spring rape seeds cultivated with the use of colloidal nanosilver and nanocopper solutions for processing seeds and as foliar fertilizer. The results show that the use of nanometals for seed processing and foliar fertilization increased the content of carotenoid pigments in the oil. The pigment concentration was higher compared to oil pressed from control seeds. The application of nanocolloids onto the seeds and subsequently on the growing plants contributed to the increase of the oxidative stability of oils. Both the acid number (AN) and peroxide number (PN) values were higher in the studied oils as compared to the control, but did not exceed the required allowable levels. Increased content of silver ions and slightly increased copper content was observed in the pressed oil. An infrared spectral analysis (Fourier-Transformed Infra-Red) conducted in combination with chemometrics allowed the classification of the studied oils in terms of their chemical composition. The analysis revealed the presence of bands characteristic of Cu-O-H vibrations after soaking the seeds and spraying the plants with copper nanocolloid, and of C-O-Ag after fertilization with silver nanocolloid.

Nutrient application is one of the major inputs required for hydroponic production of cucumbers. Reduced nutrient solution concentration with supplementary foliar fertilizer application may maintain yield and quality of mini-cucumber, while decreasing the production costs. An experiment was conducted to determine the effect of foliar fertilizer in combination with reduced nutrient concentrations on the yield and quality of hydroponically grown mini-cucumber in a plastic tunnel. Mini-cucumber plants were grown in sawdust, fertigated with nutrient solutions containing 100% (control), 75%, 50%, or 25% of the recommended nutrient concentration (NC) and two foliar fertilizer applications (no foliar and foliar application). The highest fresh and dry weight of mini-cucumber plants were obtained with 75% and 100% NC and decreased with 50% to 25% NC application. The number of marketable fruit and marketable yield on mini-cucumbers increased with 75% to 100% NC, followed by 50% NC, as compared with 25% NC. Deformed fruit were significantly lower at 25% NC than at 50%, 75%, and 100% NC. Foliar fertilizer application did not have an effect on mini-cucumber yield, but reduced the yellowing of fruit. Fruit mineral content (P, Fe, and Mn) was significantly improved by 100% NC. Improvement in yield at 75% and 100% NC was as a result of improved plant height, leaf chlorophyll content, plant fresh and dry weight, and the increase in nutrient uptake of N, P, K, and Mn, which was evident in the analysis of cucumber leaves. The reduced NC of 75% can maintain yield and quality of mini-cucumbers, whereas the application of foliar fertilizer had a limited effect.

The changes of tenderness of three green pea varieties with different maturity were studied after Fertileader® Vital fertilizer treatment. The fertilizer treatment caused signifi cant differences in the tenderness of treated plants in every year. After the second measuring time; the treated plants showed better quality than the control ones. The treated varieties kept their tenderness longer due to this foliar fertilizer, the yield have better quality so even better suited to the requirement of canning industry. Use of Fertileader® Vital is of an economic importance because high economic benefi t can be realized in one hectare after Fertileader® Vital treatment. By using this foliar fertilizer 12,840 HUF extra profi ts can be realized by producing green peas of I. quality class instead of yield with II. quality category. This extra profit could increase to 447,840 HUF considering that green peas belong still to the II. quality class after fertilizer treatment when the quality of non-treated plants are no more suitable for the canning industry.

O objetivo deste trabalho foi avaliar o efeito da adubação foliar com fósforo aplicada em diferentes estádios de desenvolvimento, na produtividade e no potencial fisiológico de sementes de soja cultivar M6410 IPRO recém-colhidas e após o armazenamento por 180 dias em condições controladas. Foi avaliada a influência do adubo foliar fosfatado nos seguintes estádios de desenvolvimento “V5, R2, R4, V5+R2, V5+R4, R2+R4 e V5+R2+R4” na dose de 2,0 l ha-1. A qualidade fisiológica das sementes foi avaliada por meio da germinação, primeira contagem, índice de velocidade de germinação e emergência, envelhecimento acelerado, teste de frio, emergência a campo, tetrazólio e desempenho de plântulas. Os componentes de produtividade de sementes de soja não foram influenciados pela aplicação de adubo foliar com fósforo nas diferentes fases fenológicas. A aplicação nos estádios V5 e V5+R2+R4 proporcionou sementes com elevada germinação e vigor, no entanto, o armazenamento por 180 dias mesmo sob condições controladas prejudica o potencial fisiológico das sementes.   Palavras-chaves: Glycine max, adubação fosfatada, vigor, armazenamento.   PHYSIOLOGICAL POTENTIAL OF SOYBEAN SEEDS PRODUCED WITH PHOSPHATE FOLIAR FERTILIZER   ABSTRACT: Phosphorus is one of the most limiting macronutrients for soybean productivity, and it may influence the physiological quality of seeds. The focus of this study was to evaluate the effect of foliar fertilization with phosphorus used in different plant stages in productivity and physiological quality of soybean seeds cv. M6410 IPRO. The influence of foliar fertilization was measured in different plant stages of development “V5, R2, R4, V5+R2, V5+R4, R2+R4 e V5+R2+R4” and the dose was 2,0 l ha-1. The physiological quality of seeds was evaluated by germination, first score, rate of germination speed and emergence speed, field conditions emergence, tetrazolium test, seedlings performance, cold test and accelerated aging. The yield components of soybean seeds were not influenced by the period of foliar fertilization application with phosphorus. The application on V5 and V5+R2+R4 stages provided seeds with high germination and vigor. However, storage for 180 days even under controlled conditions reduced the seeds physiological potential.   Keywords: Glycine max, phosphate fertilization, vigor, storage.
