The Effects of Foliar Vermicompost Applications on Yield and Some Yield Components in Triticale Varieties

Vermicompost fertilizers have started to attract attention in agriculture last years. Various liquid vermicompost fertilizers are produced and used in agriculture and some of them known as vermiliquer, vermi leachate, vermi tea or vermicast with little differences. This study is aimed to determine the effects of foliar application of liquid vermicompost fertilizer on yield and some yield components on some Turkey triticale varieties under Central Anatolian conditions in Kırıkkale province during the growing period 2014-15 and 2015-16. Six different (control, 75, 150, 250, 350 and 450 cc da-1) liquid vermicompost fertilizer doses were applied by the foliar spraying method at the beginning and end of March in both years to the five Turkey triticale varieties (Alperbey, Mikham 2002, Tatlıcak 97, Karma 2000 and Ümranhanım). According to the results, plant height, grain number and grain yield in spike, grain yield per decare, harvest index and protein content results were found to be significant in fertilizer × variety × year interaction. There is also a statistically significant difference between thousand-grain weight and the variety x fertilizer doses interaction, and between varieties and fertilizer doses in terms of spike length. The positive effects of liquid vermicompost fertilizer doses, except 450 cc da-1, were determined in varieties. It was observed that a satisfactory yield can be obtained from 250 cc da-1 in the absence of nitrogen fertilizers as the top fertilizer. It could be deduced that 250-350 cc da-1 doses of vermicompost fertilizer can be applied in triticale based on varying ecological conditions and varieties in Central Anatolian ecological conditions.

SUMMARYTen leading varieties of winter wheat released during 1950–2009 in North China were tested in a free-air temperature increase (FATI) facility. The FATI facility mimicked the local air temperature pattern well, with an increase of 1·1 °C in the daily mean temperature. For all the tested varieties, warming caused a significant reduction in the total length of wheat growth period by 5 days and especially in the pre-anthesis period, where it was reduced by 9 days. However, warming increased wheat biomass production and grain yield by 8·4 and 11·4%, respectively, on an average of all the tested varieties. There was no significant difference in the warming-led reduction in the entire growth period among the tested varieties. Interestingly, the warming-led increments in biomass production and grain yield increased along with the variety release year. Significantly higher warming-led increases in post-anthesis biomass production and 1000-grain weight were found in the new varieties compared to the old ones. Meanwhile, a significant improvement in plant productivity was noted due to wheat breeding during the past six decades, while no significant difference in the length of entire growth period was found among the varieties released in different eras. The results demonstrate that historical wheat breeding might have enhanced winter wheat productivity and adaptability through exploiting the positive effects rather than mitigating the negative impacts of warming on wheat growth in North China.

An experiment was conducted under laboratory and field conditions in order to evaluate the effects of different priming treatments, specifically KNO3 (1%), KCl (2%), KH2PO4 (1%), ZnSO4 (0.05%), PEG-6000 (20%), IBA (100 ppm), Mannitol (4%), GA3 (100 ppm) and distilled water, on seed germination properties and several agro-morphological plant characteristics of red lentil. Seeds not primed were used as a control. GA3 treatment increased shoot length. The control (non-primed seeds) treatment resulted in increased seedling root number and length. Distilled water, ZnSO4 and control treatments increased germination rate and percentage. In the pot experiments, GA3 treatment increased plant height and seedling emergence rate, whereas KCl treatment improved the number of nodules, as well as root and shoot dry weight when compared to the control. ZnSO4 treatment increased yield components and grain yield in field conditions. The results of this study showed that ZnSO4, GA3 and PEG-6000 seed priming treatments may be useful tools due to their positive effects on germination rate, germination percentage, yield component and grain yield of lentil.

Cent Level

Calcium nitrate and ammonium nitrate limestone (»Oulunsalpietari») were compared as the nitrogen fertilizer for oats in 15 field trials and for barley in one trial. The trials were carried out in summers 1959 and 1960 in various places in Finland. The split plot technique was employed in order to reduce the variation as much as possible. In 1959 the amounts of nitrogen applied as these two fertilizers to the corresponding halves of the plots were 25 and 50 kg/ha. In 1960 also higher applications were used: 75 and 100 kg/ha of N. In three trials these fertilizers were compared both as a surface dressing and worked in. Visual observations suggested about 5—6 weeks after sowing a darker green colour in the stands treated with calcium nitrate as compared with the other half treated with ammonium nitrate limestone. These differences later disappeared. In some trials a higher nitrogen content of the plants from the calcium nitrate stands could be demonstrated during this period. The uptake of nitrogen by plants was regularly followed throughout the growing period. Owing to the large variation, usually, no statistically significant difference between the effect of the fertilizers could be detected. In a few cases the superiority of calcium nitrate could be demonstrated. No differences in the ripening could be found. In most trials there was a fairly regular tendency to higher yields and higher nitrogen content in the grain and straw produced by calcium nitrate. Yet, only in a few cases were the differences statistically significant at the five per cent level. Thus, it was concluded that on the basis of the results of these trials ammonium nitrate limestone and calcium nitrate may be considered practically equal as nitrogen fertilizers for oats. There was no difference in the yields of barley produced by these two fertilizers, but the nitrogen content of grains was significantly lower with ammonium nitrate limestone than with calcium nitrate. This may be worth further study in connection with the production of malting barley.

Grain Yield Components

Variability of grain yield components of some new winter wheat genotypes (e.g. Lara, Lenta, Kruna, Fiesta, Perla, and one line of AG-45) was examined. The analysis of grain yield components of these genotypes and the line was undertaken in a two-year research (1997/1998 and 1998/1999) at two different locations. Significant differences among genotypes, locations and research years were established. In the first experimental year (1997/1998) there was a high positive correlation between nearly all components of the grain yield. The most significant correlation was found between the grain number per spike and grain yield. In the second experimental year (1998/1999) the components did not show statistically significant correlation with the grain yield. It seems that the grain yield of examined genotypes depended significantly on the grain number per spike, grain mass per spike, and agroecological conditions during the vegetation period, whereby the potential yield was determined by the interaction among genotypes, location and production year. The biggest differences among examined genotypes of winter wheat were found in the stem height and spike length.

The trial included two spelt cultivars: Nirvana and Ostro, three seeding rates: 200, 300, and 400 germinated seeds/m2, and a fungicide treatment (tebuconazole). Cultivar Nirvana produced a significantly higher grain yield in both trial years, higher number of spikelets per spike, higher grain number and mass per spike. Cultivar Ostro had a significantly higher grain crude proteins content, higher 1000 grain weight, and also a higher number of sterile spikelets per spike. No significant effect of seeding rate on grain yield was determined while the fungicide treatment had a significant effect on grain yield only in the warmer year 2008/2009.

The objective of the study was to evaluate the effect of foliar application of urea and urea-formaldehyde, triazone-based fertilizers on soybean and corn crops. Four experiments were carried out, two on soybeans, one on first season corn, and the other on second season corn. The experiments were conducted using a randomized block design, with 5 treatments studied: T1—control without application of foliar nitrogen (N); T2—foliar application of conventional urea solution and three treatments with Hexion foliar fertilizers based on urea-formaldehyde and triazone (N-Hexion®), with varying levels of N and slow-release components; T3—Hexion 1; T4—Hexion 2; and T5—Hexion 3. The foliar application of conventional urea showed no statistically significant difference in relation to the control for the yield components and grain yield for the soybean crops in seasons 2018–2019 and 2019–2020. Urea-formaldehyde/triazone treatments showed a significant increase in yield for soybeans in the 2018–2019 season compared to the control and to conventional urea. Nitrogen fertilizers with high percentages of slow-release compounds promote nitrogen release more slowly, which led to no significant increase in yield for Hexion 1. No statistical differences were observed in the corn yield for the first and second crop.

Grain Number Per Spike

Abstract Key message We discovered a natural FT-A2 allele that increases grain number per spike in both pasta and bread wheat with limited effect on heading time. Abstract Increases in wheat grain yield are necessary to meet future global food demands. A previous study showed that loss-of-function mutations in FLOWERING LOCUS T2 (FT2) increase spikelet number per spike (SNS), an important grain yield component. However, these mutations were also associated with reduced fertility, offsetting the beneficial effect of the increases in SNS on grain number. Here, we report a natural mutation resulting in an aspartic acid to alanine change at position 10 (D10A) associated with significant increases in SNS and no negative effects on fertility. Using a high-density genetic map, we delimited the SNS candidate region to a 5.2-Mb region on chromosome 3AS including 28 genes. Among them, only FT-A2 showed a non-synonymous polymorphism (D10A) present in two different populations segregating for the SNS QTL on chromosome arm 3AS. These results, together with the known effect of the ft-A2 mutations on SNS, suggest that variation in FT-A2 is the most likely cause of the observed differences in SNS. We validated the positive effects of the A10 allele on SNS, grain number, and grain yield per spike in near-isogenic tetraploid wheat lines and in an hexaploid winter wheat population. The A10 allele is present at very low frequency in durum wheat and at much higher frequency in hexaploid wheat, particularly in winter and fall-planted spring varieties. These results suggest that the FT-A2 A10 allele may be particularly useful for improving grain yield in durum wheat and fall-planted common wheat varieties.

In order to study the effect of different manure and chemical fertilizer levels on qualitative and quantitative characteristics of safflower in the condition of irrigation with municipal wastewater, an experiment was conducted as split plot basis of randomized complete design in Lakhshah region locate in Zahedan city, Iran. The treatments were comprised of two levels of irrigation, W1= Well water and W2= Treated wastewater, in main plots and sub plots consisted of F1: control (without consumption of manure and chemical fertilizer), F2: Recommended manure, F3: Half of recommended manure and chemical fertilizer (N, P and K), and F4: Recommended chemical fertilizer (N, P and K). The results showed that Treatment of treated wastewater had a positive and significant influence on all yield components, and the most influence was shown on 1000 seed weight. Also, irrigation with wastewater significantly increases the dry and fresh yield and grain yield of safflower than ordinary water. Among the fertilizer treatments, complete treatment of chemical fertilizer N, P and K had the greatest effect on increase of yield and grain yield components. In this experiment, water treatment hadn’t significant effect on accumulation of Cr, pb, Fe and Mn in safflower grain, and soil. While, fertilizer treatment had only a significant influence on the accumulation of Fe and Mn in safflower grain, but between these treatments wasn’t saw any significant difference on the accumulation of Cr and pb. In general, the results of this experiment showed that irrigation with wastewater and application of complete fertilizer with manure is recommended.

The aim of this study was to determine the effect of fertilization with organic fertilizers Fertil Supernova and Ilsamin N90 on the yield and yield components of three spelt varieties. The study was conducted on an anthropogenized eutric cambisol at the experimental site of the Faculty of Agriculture in Zagreb during 2015/16, 2016/17, and 2017/18, respectively. The study included three varieties of spelt, Nirvana, Ostro, and Bc Vigor, as well as a topdressing with organic fertilizers and a control (without topdressing). The first topdressing at the beginning of spring vegetation consisted of the application of organic fertilizer Fertil Supernova in the amount of 300 kg ha-1, while the second topdressing at the end of tillering consisted of a foliar application of Ilsamin N90 in the amount of 3 l ha-1. The spelt yield and its yield components were significantly influenced by weather conditions, primarily by the amount and distribution of precipitation. The studied spelt varieties did not significantly differ in the grain yield. In all three research years, the variety Nirvana has achieved the significantly largest number of ears per m2. Topdressing with organic fertilizers had a positive impact on the yield of the hulled spelt grain only in the dry year of 2016/17. Topdressing with organic fertilizers did not have a significant impact on the yield components.

Maize inoculation with bacteria of the genus Azospirillum can reduce the consumption of nitrogen fertilizers to obtain maximum grain yield. In this context, the aim was to evaluate the effect of inoculation with Azospirillum brasilense associated with nitrogen fertilization on the maize agronomic performance. A randomized block design was used in a split-plot scheme with four replicates. Four inoculation managements with Azospirillum brasilense (T0 - control without inoculation; TC2 - seed box inoculation, 200x108 viable cells ha-1; TC3 - seed box inoculation, 400x108 viable cells ha-1; TS1 - previous inoculation of the seeds, 600x108 viable cells ha-1) associated with four top-dressing N doses (0, 60, 120 and 180 kg ha-1), applied at maize stage V6 by urea. Inoculation with Azospirillum brasilense associated with top-dressing nitrogen fertilization increases the number of grain rows per ear, number of grains per row, number of grains per ear and grain yield of maize, mainly due to its positive effects on plant nutrition. Managements with seed box inoculation with 400x108 viable cells per ha (TC3) and inoculation in seed pre-treatment (TS1) are the most recommended for maize.
