The aim of the paper is to show the reaction of maize crop to the foliar application of new biofertilizers, obtained from the residues left after the wool tanning process and which are based on protein hydrolysates of keratin and collagen. The tests have been performed in microplots (10 sqm) and macroplots (1000 sqm), in three repetitions, in southern Romania. All data obtained as a result of the 2020 autumn harvest have been centralized in tables and statistically processed, in order to establish the influence of each product, compared to the control. The bifactorial analyses show that, in climatic stress conditions (prolonged drought – Calarasi), very significant increases in yield have been obtained with K4 (2.5 and 5.0 l/ha), K5 (5.0 l/ha) and C (5.0 l/ha), with increases between 700 and 1300 kg/ha, ie up to +24%. In macroplots, subject to a moderate drought (Teleorman), product C (5.0 l/ha) brought a yield increase of 1537 kg/ha (+26%), noting that in this location almost all tested biostimulators offer very significant yield growth (except KC). Based on the 2020 yields, it was possible to identify which the foliar biostimulators that will continue to be tested in 2021.

The present study aimed to evaluate the productive performance of maize crop when seed inoculated with A. brasilense, associated with different foliar doses of magnesium in the crop vegetative stages. For this, two essays were conducted in field conditions, one located in Laranjeiras do Sul-PR and the other in Entre Rios do Oeste-PR. A randomized blocks scheme was used, with a 3 × 2 factorial, being the treatments with magnesium (Mg): magnesium sulphate; magnesium oxide and without magnesium, and the presence or absence of seed inoculation with A. brasilense. The magnesium sources were supplied via foliar at the V4 stage of the crop, using doses of 6 kg ha-1. Evaluations were carried at R1 determining the SPAD index and stem diameter and, at the end of the productive cycle, were evaluated production components and yield. In both sites no significant effects of foliar application with Mg were observed over the evaluated parameters. The A. brasilense inoculation provided an increase of 9.66% and 6.32% in stem diameter and of 6.8% and 6.24% in the SPAD index in Laranjeiras do Sul and Entre Rios do Oeste respectively, however, they did not increase production components and yield. It is concluded that the inoculation with A. brasilense increases of stem diameter values and SPAD index, in turn the foliar fertilization with different sources of magnesium do not interfere in the development and productivity of corn crop.

Water shortage and drought are a growing problem in Europe. Therefore, effective methods for limiting its effects are necessary. At the same time, the “field to fork” strategy adopted by the European Commission aims to achieve a significant reduction in the use of plant protection products and fertilizers in the European Union. In an experiment conducted in 2018–2020, the effect of the method of foliar fertilization containing silicon and potassium on the yield and technological quality of sugar beet roots was assessed. The fertilizer was used in seven combinations, differing in the number and time of application. The best results were obtained by treating plants during drought stress. The better soil moisture for the plants, the smaller the pure sugar yield increase was observed. It is difficult to clearly state which combination of silicon and potassium foliar application is optimal, as their effects do not differ greatly.

RESUMO – O milho é uma planta monoica, e a geração de novos híbridos exige a remoção do pendão das plantas.Sabe-se que a remoção do pendão possui efeito negativo na produtividade da cultura. Contudo, a aplicação de Ncomplementar, via foliar, poderia minimizar essas perdas. Assim, o objetivo deste estudo foi avaliar como o Ncomplementar afeta a produtividade e os componentes de rendimento da cultura do milho submetida ao despendoamento.O estudo foi conduzido em delineamento de blocos casualizados em esquema fatorial 2 x 3 x 5, sendo duas safras(2014/15 e 2015/16), três momentos de despendoamento (sem despondoamento, arranquio de 2-3 folhas e arranquiode 4-5 folhas antes do pendoamento) e cinco doses de N complementar (0, 5, 10, 15, 20 L ha-1) aplicadas no estádio depré-pendoamento (VT). Não foi verificada interação N complementar X despendoamento para nenhuma das variáveisestudadas. A menor produtividade foi verificada no despendoamento de 4-5 folhas. A aplicação de N complementaraumentou a produtividade da cultura do milho, e a aplicação de 11,5 L ha-1 incrementou a produtividade em 448 kgha-1. O despendoamento diminuiu a produtividade da cultura do milho, quanto mais precoce o despendoamento, maisnegativo é o efeito na produtividade.Palavras-chave: Melhoramento genético, N complementar, pendoamento, produção de sementes, Zea mays.FOLIAR APPLICATION OF COMPLEMENTARY NITROGEN,IN MAIZE SUBJECTED TO DETASSELINGABSTRACT – Maize is a monoic plant and the generation of new hybrids requires the removal of the tassel from theplants, which has a negative effect on crop yield. However, the use of complementary leaf nitrogen (N) fertilization,could minimize the yield losses. Therefore, the objective of this study was to evaluate the effect os the application ofcomplementary N affects on yield of the maize crop subjected to detasseling. The study was carried out in a randomizedcomplete block design, with a 2 x 3 x 5 factorial scheme and four replications. Two growing seasons (2014/15 and2015/16), three detasseling moments (without detasseling, detasseling of 2-3 leaves, and detasseling of 4-5 leaves)and five doses of complementary N (0, 5, 10, 15, 20 L ha-1) applied at the VT stage. There was no interaction betweencomplementary N and detasseling for any of the variables studied. The lowest yield was verified with the detasselingof 4-5 leaves. The application of complementary N showed a positive effect on maize yield, and the application of 11.5L ha-1 of complementary N provided yield increase of 448 kg ha-1. The detasseling technique had negative effects onmaize crop yield, the earlier is the detasseling, the more negative is the effect on yield.Keywords: Genetic improvement, Seed production, tasseling, Zea mays.

A field experiment with split-split plot design (SSPD) was conducted to study the response of two winter wheat (Triticumaestivum L.) cultivars (viz. salt tolerant cultivar KRL-1-4 and salt non-tolerant cultivar HD-2894) under saline irrigation regimes with and without foliar potassium fertilization on growth and grain yield of wheat during rabi 2011-12 and 2012-13. Potassium in the ratio of K+: Na+ (1: 10) was applied as foliar application during the heading stage of the crop. Results showed that the grain yield of KRL-1-4 and HD-2894 cultivars with foliar potassium fertilization at the heading stage increased by 6.5 to 22% and 3 to 15% during rabi 2011-2012, respectively under different saline irrigation regimes as compared to the control. Moreover, the results of rabi 2012-13 showed an increase in grain yield ranging from 4.5 to 20% for KRL-1-4 as compared to the control. Statistical analysis of grain yield parameter showed that the foliar potassium application in both varieties resulted in significant yield difference at 0.05 probability level as compared to the non-foliar application. Overall, it was observed that the foliar potassium fertilization increased the grain yield of both wheat cultivars, while the salt tolerant cultivar performed better than the salt non-tolerant cultivar under irrigated saline regimes.

SummaryIn this study two field experiments were conducted on a heavy to medium heavy, calcareous, recent alluvial soil of Central Greece. The main aim of these experiments was to study the effect of the most common nitrogen sources, applied in one or two doses, on maize growth and fertilizer utilization. Foliar application of urea was also a treatment included in these experiments.Phosphorus alone had no significant effect on maize yield. Nitrogen (various forms), alone or in combination with phosphorus, increased the yield and nitrogen content of maize. Maize yield was not significantly affected by the form of nitrogen or by dividing the application of nitrogen. Foliar applications of urea were as effective as soil applications in increasing maize grain yields.The percentage of fertilizer nitrogen taken up (utilization coefficient) ranged between ca. 58% for sodium nitrate and ammonium nitrate, and ca. 39% for ammonium sulphate and urea, when the fertilizers were applied about 10 weeks after sowing. Foliar urea was nearly as efficiently utilized as urea applied as a sidedressing. Application of the tested fertilizers before sowing was nearly as efficient as or more efficient than application of the fertilizers as a sidedressing at 70 cm plant height (38 days after sowing). Finally, addition of 120 kg N/ha enhanced the amount of soil nitrogen taken up in the maize crop by 33%.

Yield Responses

Significant yield responses of up to 0.9 t/ha were obtained with the nematicides aldicarb and dibromochloropropane in seven of eleven field trials with the wheat variety, Condor. Both nematicides reduced the numbers of white cysts of Heterodera avenae on the roots of wheat. With aldicarb the increase in wheat yields varied directly as the decrease in white cysts: dibromochloropropane gave similar increases in yield as aldicarb with a greater reduction in cyst numbers. There was no yield increase with either nematicide when cereal cyst nematode was not present. An analysis of covariance indicated that over all the sites 64% of the increase in yield due to aldicarb could be explained in terms of cysts of cereal cyst nematode.

Clubroot, caused by Plasmodiophora brassicae, is an important constraint on canola (Brassica napus) production in Canada. Rotations of clubroot-resistant (CR) canola cultivars in various sequences and planting intervals between canola with non-host crops and fallow periods were evaluated to determine their effects on clubroot severity and P. brassicae resting spore populations under field and micro-plot conditions. Under micro-plot conditions, the rotation sequences including CR canola, continuous fallow, and the non-host barley reduced gall weight by 63%–100% and clubroot severity by 34%–100% compared with continuous planting of susceptible canola. No visible clubroot symptoms developed following continuous fallow or the non-host crop. Under field conditions, clubroot severity was very high (78% disease index) in the continuous susceptible canola sequence. Most of the CR canola rotation sequences significantly reduced clubroot severity by 12%–23%, but continuous fallow, continuous barley, and alternating the CR canola cultivars ‘45H29’ or ‘73-47’ with ‘TC72429-10’ reduced clubroot severity by 32%–36%. A comparison of intervals between canola crops and four cropping sequences (continuous susceptible canola, alternating canola with barley or pea, a 2-yr non-host interval between canola crops, and a 3-yr non-host interval between canola crops) was conducted over 5 yr. A 2- or 3-yr non-host interval improved plant height, plant biomass, and seed yield, and reduced gall mass, P. brassicae propagules in the soil, and clubroot severity. A significant yield increase of more than 3600% was observed in a 3-yr non-host interval.

AbstractTitanium is one of a plant biostimulators. It stimulates life processes, growth and development, as well as affects physiological and biochemical pathways, often increasing biomass production and enhancing yield. An open field experiment was conducted in the years 2011-2013 in Polanowice, Poland to investigate the effects of titanium foliar fertilization on the growth of timothy grass (Phleum pratenseL.). This single-factor, randomized block design study was performed in four replicates on research plots with the area of 10 m2each. The substrate was black loess soil (chernozem) typical for top class farmland. Titanium fertilizationvialeaf spray was performed with a water solution of Tytanit® at three doses of 0.2, 0.4, and 0.8 dm3· ha−1. Foliar fertilization with the highest dose of Tytanit® significantly increased seed yield, thousand grain weight and germination capacity. Moreover, the middle dose of Tytanit® (0.4 dm3· ha−1) was enough to observe a positive effect on the sample.

Abstract A pot experiment conducted in a growth chamber studied the effectiveness of foliar fertilization of spinach (Spinacia oleracea L.), with different forms of nitrogen applied with the air temperatures: 5°C, 15°C and 25°C. Nitrogen was supplied three times in the form of 1% water solutions of CO(NH2)2, NH4NO3, NH4HCO3 and Ca(NO3)2 × 4 H2O, with water as the control. The obtained results showed that nitrogen in the form of Ca(NO3)2 × 4 H2O - independent of the air temperature during solution application - is the least useful in foliar fertilization of spinach leaves, whereas the effectiveness of the other forms was similar, although the best effects were given by NH4NO3. Application of all forms of nitrogen at the air temperature of 25°C had the most positive effect on the course of gas exchange (stomatal conductivity, photosynthesis, transpiration). Despite that, the highest leaf yield with the highest content of nitrogen, total chlorophyll (a + b), carotenoids and vitamin C, and the lowest content of nitrates, was given by plants with foliar application of all nitrogen forms at the temperature of 15°C.
