Aleksander SZMIGIEL,Andrzej OLEKSY,Anna LORENCKOZIK
Journal of Central European Agriculture , 2013, DOI: 10.5513/jcea01/14.1.1207
Abstract: The research aimed to determine the effect of mineral fertilization (NPK) on grain yield of maize in various earliness classes. The field experiment was conducted on very good wheat soil complex (degraded chernozem formed from loess) in the years 2006-2009. The analysed factors were NPK fertilization with 150; 300; 450 kgha-1 and non-fertilized treatment. The second order factor was three maize cultivars: early Fido c.v., medium early Grom c.v. and medium late PR38F70. Increase in mineral fertilization (NPK) level influenced a growth of maize grain yield from 8.39 tha-1 on the non-fertilized treatment to 10.69 tha-1after the application of the highest fertilizer dose.

Abstract: On the basis of a 4–year study, the effect of fertilization methods on the uptake and accumulation of mineral components by maize was evaluated. Two methods were used: by broadcasting over the whole surface and by band fertilization. The applied fertilizer level was gradually increased from 17.4 to 56.7 kg P ha-1 with the use of superphosphate and ammonium phosphate. It was found that the uptake and accumulation of mineral components depended on all the studied factors and their effect was increasing with the advancing vegetation. Band fertilization and the use of ammonium phosphate kept increasing the accumulation of all mineral components from 4-5 to 8-9-leaf-stage, in comparison with broadcast fertilization and superphosphate application, respectively. No distinct effect of phosphorus fertilization level on the uptake and accumulation of mineral components was visible before the stage of 8-9 leaves. Regressions were calculated for the relationship between the mineral components accumulation and the lapse of time from emergence to 8-9-leaf-stage and for the relationship between the uptake of mineral components and the accumulation of dry matter.

Abstract: the effect of organic manure on the community of mycorrhizal fungi (amf) was evaluated in maize, cowpea and cotton intercropping systems in a semi-arid region of brazil over two consecutive years. the experiment was conducted using a randomized block design with four replicates and six soil treatments: (m) goat manure incorporated in the soil before planting; (g) gliricidia prunings incorporated before planting; (m+g) manure and gliricidia incorporated before planting; (gs) gliricidia applied on the soil surface 45 days after planting; (m+gs) manure incorporated before planting and gliricidia applied to the surface 45 days after planting; and (c) control treatment without incorporation. it was not possible to identify the best treatment for both years in terms of spore density, mycorrhizal colonization and glomalin content. however, there was a significant effect from the fertilization treatments when compared to the control in most treatments. in both years, m+gs favored glomalin and amf sporulation in the cotton plots. in the second year, which had low rainfall, there was an increase in production of spores, glomalin, colonization and amf species richness irrespective of soil incorporation and culture. plots that were fertilized with manure presented greater amf species richness regardless of the year and crop type.

Abstract: Based on a field study of the aquic brown soil in the suburbs of Shenyang City in Northeast China over a consecutive 19 years, the effects of fertilization and soil management on the microbial biomass (C and N) and communities were investigated. The results showed that microbial biomass of the bare land and farmland was low. Fertilization increased the microbial biomass, especially when mineral fertilizers and pig manure (NPK+M) were applied. DGGE fingerprinting indicated a high similarity in the distribution of most bacterial bands among all treatments, and the bacterial diversity of the bare land was the highest. There were significant variations of fungal community structure among different treatments. Long-term fertilization increased fungal diversity and manure was more effective than mineral fertilizer to increase fungal diversity. Long-tem fertilization and soil management had a large effect on the ammonia-oxidizing bacteria structure in soil. Moreover, manure and mineral fertilizer influenced the ammonia-oxidizing bacterial communities in different ways. When applied together NPK+M increased the diversity most significantly. On the contrary, fertilization and soil management had less effect on the bacterial communities. Cluster analysis suggested that soil management practice had a larger effect on the community structures of bacteria, fungi and ammonia-oxidizing bacteria than fertilization.

Research Journal of Agronomy , 2012,
Abstract: This study was conducted to determine the effect of cow dung (manure) alone (CD), zinc sulphate alone, ZnSO4 (23% Zn) and their organo-mineral combination (CD+ZnSO4) on the performance of maize (Zea mays) at the Teaching and Research Farm of the University of Ado-Ekiti. The fertilizer treatments consisted of 0, 15 and 30 mg Zn kg 1 soil to give 9 treatment combinations replicated three times in a Complete Randomized Design (CRD). Growth parameters were measured at 7, 14, 21 and 28 days of growth while shoot weight and Zn uptake by the crop were determined at 28 days after planting. The result indicated that application of 30 mg Zn kg 1soil and organo-mineral combination (Cow dung+ZnSO4) significantly (p< 0.05) gave the highest plant shoot biomass (7.11 g pot 1) base on dry shoot weight. Also application of CD also led to the highest Zn uptake.

Abstract: Effect of different rates of hydrated lime and zeolite tuffs, as lime materials, mineral and organic fertilizers upon the yield of maize and winter wheat grain was studied in an exact field trial set up on Eutric Gleysol, near Karlovac, Central Croatia. The following crops were cultivated during the study period: 1999 and 2001 – maize, 1999/00 and 2001/02 – winter wheat. In the first investigation year, the highest yield of maize grain of 9.78 t ha-1 was achieved with the combination of the higher mineral fertilizer rate and the higher rate of farmyard manure. In the following year, the highest yield of winter wheat grain of 5.85 t ha-1 was achieved with the combination of the higher mineral fertilizer rate and the higher rate of hydrated lime. In the third and fourth investigation years, the highest yields of maize grain (10.05 t ha-1) and wheat (5.48 t ha-1) were recorded for the combination of the higher rates of mineral fertilizers and hydrated lime. The foregoing allows the conclusion that mineral and organic fertilization combined with hydrated lime is the optimal solution for increasing the yields of test crops.

Abstract: 研究了旱地不同栽培模式(全膜双垄沟和传统种植模式)和施氮量(0、170、200、230 kg·hm-2)对春玉米生长期间矿质氮和产量的影响。结果表明:不同处理条件下,硝态氮主要分布在0~40 cm土层,施氮量越高土壤中硝态氮的含量也就越高,随土层深度增加硝态氮含量降低;不同栽培模式对土壤中硝态氮的分布有明显影响,全膜双垄沟模式有助于玉米植株高效吸收利用土壤中的氮素,施氮量为0、170、200、230 kg·hm-2处理的吸氮量分别提高了89.3%、51.1%、66.6%和102.8%,所有处理的吸氮量平均提高77.4%,从而减少土壤硝态氮的残留,而传统种植模式的玉米植株利用土壤氮素效率低,易造成硝态氮残留在土壤中,当遇到强降雨时硝态氮的淋洗现象严重,将硝态氮迁至作物法吸收利用的土壤深度,造成资源浪费;而铵态氮在土壤中不易迁移,施氮量、栽培模式及玉米不同生育时期对铵态氮在土壤剖面中的分布几乎没有影响;玉米的植株吸氮量与玉米产量成正比,施氮处理植株吸氮量与产量显著高于不施氮处理,但是不同施氮处理间的差异不显著。全膜双垄沟模式下春玉米的最佳施氮量为200 kg·hm-2,而传统种植模式下的最佳施氮量为170 kg·hm-2,且在干旱地区宜采用全膜双垄沟栽培模式种植春玉米。
A field experiment was carried out to study the effects of different cultivation patterns (the whole film double furrow mode and traditional planting pattern) and nitrogen application rate (0, 170, 200, 230 kg·hm-2) on the soilmineral nitrogen and grain yield of spring maize. The results showed that in the 0~200 cm soil profile, soil nitrate content was decreased as the depth of soil layers increased and the soil nitrate was mainly distributed in the 0~40 cm soil profile. With the increase of nitrogen application, soil nitrate content became increased. Different cultivation patterns had significant influences on the distribution of nitrate in soil. Compared to the traditional planting pattern, the whole film double furrow planting pattern reduced the soil nitrate due to the ability improvement of the plant N uptake from the soil. The N uptake of treatment N0, N170, N200, N230 were increased by 89.3%, 51.1%, 66.6% and 102.8%, with an average of 77.4%. In contrast to the soil nitrate, the ammonium in the soil was changed very slightly and was not affected by the amount of nitrogen application, cultivation patterns or different growth stages of spring maize. Compared to the traditional planting pattern, the whole film double furrow planting pattern could significantly improve grain yield and plant N uptake. In summary, the optimum nitrogen application rate of the whole film double furrow mode was 200 kg·hm-2, while the traditional planting pattern was 170 kg·hm-2. In conclusion, the whole film double furrow mode was more suitable for spring maize in dryland regions.

Abstract:
Rice is one of the staple crops in Burkina Faso. However, the local production covers only 47% of the population demands. One of the main reasons of the poor productivity in Burkina Faso is iron toxicity which is related mainly to the activity of Iron Reducing Bacteria in the rice field’s ecosystems. In order to control the harmful effects of Iron Reducing Bacterial populations and to improve rice productivity, a pots experiment was conducted at the experimental site of the University Ouaga I Pr. Joseph KI-ZERBO. An iron toxic soil from Kou Valley (West of Burkina Faso) and two rice varieties, BOUAKE-189 and ROK-5, sensitive and tolerant to iron toxicity, respectively, were used for the experiment. The pots were drained for 14 days (D2) and amended with chemical fertilizers (NPK + Urea and NPK + Urea + Ca + Mg + Zn complexes). Control pots without drainage and fertilization (D0/NF) were prepared similarly. The kinetics of Iron Reducing Bacterial populations and ferrous iron content in soil near rice roots were monitored throughout the cultural cycle using MPN and colorimetric methods, respectively. The total iron content was evaluated in rice plant using a spectrometric method. Data obtained were analyzed in relation to drainage and fertilization mode, rice growth stage and rice yield using the Student’s t-test and XLSTAT 2014 statistical software. The experiment showed that the combined application of subsurface drainage and NPK + Urea + Ca + Mg + Zn fertilization, reduced significantly the number of IRB in the soil near rice roots for both rice varieties (p = 0.050 and p = 0.020) increased the leaf tissue tolerance to excess amounts of Fe, and rice yield.
