Creating a neural network system for forecasting and managing agricultural production using autocorrelation functions of time series

The article considers the features of creating an artificial neural network (ANN) for modelling and forecasting the dynamics of long-term time series (TS) levels of grain yield in arid conditions on the example of the Lower Volga region of the Russian Federation. In order to increase the validity of the choice of architecture and macroparameters developed by ANN, statistical characteristics of the simulated TS were analysed. The autocorrelation function of distribution of levels of long-term series of grain yields is constructed. It is proposed to take into account the characteristics of time lags of autocorrelation functions when selecting ins macroparameters for predicting BP yield. On the basis of preliminary statistical analysis, "peaks" corresponding to the time lags of the autocorrelation function, whose values are determined for different groups of grain crops, are identified. The obtained values are recommended to be taken into account when selecting the value of the time window parameter when constructing neural network models of productivity. This is the basis of the proposed information technology for building ins for predicting crop yields. The results of neural network modelling and yield forecasting can be successfully used for managing agricultural production, including in the arid conditions of the Lower Volga region of the Russian Federation.

DEPENDENCE OF PHYTOSANITARY CONDITIONS OF CROPS AND GRAIN YIELD OF WINTER WHEAT IN THE CROP ROTATION SYSTEM ON APPLICATION LEVEL OF CHEMICALS

The article presents the study results of the field experiments on chemicals impact on phytosanitary conditions of crops and grain yield of winter wheat. Winter wheat was grown in a long-term crop rotation by the following scheme: potatoes, spring barley, pea- vetch-oat mix for green fodder, winter wheat. Phosphorus and potash fertilizers (P60K90) were applied as the background one. Nitrogen fertilizers in the form of ammonium nitrate were used on the experiment variants at the rate of N34.6 – N69.2 and N103.8. The herbicide Agritox, fungicide Alto and microelement cuprous sulphate were applied in ac-cordance with the scheme of the experiment. The statistical processing of experimental data proved that no harmful impact of pesticides on the productivity of winter wheat was observed in the years of the weak development of weeds and harmful phytopathogens. Regulating the phytosanitary condition of crops due to the winter wheat in the crop rotation, and the application of the herbicide Agritox at the rate of 1.5 kg/ha and the fungicide Alto (250 g/ha) and cuprous sulphate (350 g/ha), it is possible to achieve the planned level of winter wheat yield of 5.37-5.95 t/ha. The combined effect of nitrogen fertilizers and plant protection chemicals allows a differentiated approach to the role assessment of each studied factor de-pending on weather conditions. It has been revealed that the optimal combination of the applied means of chemicalization in the crop rotation system ensures the implementation of the planned level of grain yield of winter wheat in the range from 5.37 to 5.95 t/ha.

The consequences of change in management practices on maize yield under climate warming in Iran

The potential impacts of climate warming on grain yield, water, and nitrogen consumptions of maize have been repeatedly assessed across different regions of the world. However, to date, there is no comprehensive, large-scale evaluation on the effects of climate warming on the cropping systems of Iran. The objective of the current study was to quantify the effects of climate warming on the length of the growing period and grain yield of maize. We also tested the potential of changes in irrigation, nitrogen application rate, and using late maturity cultivars of maize to offset the negative impact of climate warming in order to maintain the current levels of grain yield (4 to 10 t ha−1 depending upon the province) in Iran. The crop modeling framework SIMPLACE was used to evaluate the effects of the warming temperatures, nitrogen application rate, and changes in thermal requirements of the cultivar scenario combinations on grain yield of maize in Iran. The climate, soil, and management inputs of the crop model were obtained from global datasets as grid cells at 0.5° × 0.5° resolution, and the outputs of the crop model were aggregated to the province level. Results of the grain yield projections showed a decline (− 0.1 to − 22%) in maize, especially in the Southern provinces (Khuzestan, Fars, and Kerman) under different warming scenarios by + 0.5 to + 2 °C, an increase from the baseline. The grain yield decline appeared to be mainly driven by a shortening of the length of the growing season and extreme heat stress during anthesis, the most sensitive period of crop growth. Increasing temperatures during the growing season lead to a marginal increase of absolute irrigation requirements over the maize growing areas. For all provinces, application of 10–25% more nitrogen than the current rate (170 kg N/ha-1) was able to offset the negative effects of higher temperatures (+ 0.5 and + 1.0 °C) during the growing season. However, the increased nitrogen application rates were not able to maintain the baseline level of grain yield under the + 1.5 and + 2.0 °C warming scenarios. Introducing late maturity cultivars, which required 20% more temperature sum than current cultivars to reach maturity, improved the grain yield in the cooler provinces by up to 10%. In conclusion, the grain yield baseline level may not be maintained under the highest magnitude of warming by increasing nitrogen application rates or using late maturity cultivars. Furthermore, more water is needed to produce a unit of grain under a warming climate. This study also suggests that combined adaptation strategies should be considered by policymakers in order to mitigate the negative impact of climate warming on the cropping systems of Iran.

Influence of relief conditions on plant growth and development

The objectives of our investigations are to describe the limits of variability of the main agricultural types of modern ukrainian winter wheat varieties in order to their relations with difference growth conditions. The most target traits for determining these relations are agronomic-value, such as yield, protein content and protein composition (amount of gliadins and glutenins). As an additional purpose we evaluated relations between relief conditions and amount of microelements and heavy metals, relation amid growth conditions and content of value microelements (nitrogen, phosphorus, potassium). Our investigations confirmed statements about relations between content of nutrient elements in winter wheat plants, their uptaking from soil, type of relief, wheat variety genotype and limits of adaptable for difference conditions. Winter wheat is an cultivar with wide, but specific demands to growth and development conditions. Due to relief conditions, north exposition of the slope gives more advantages for winter wheat vegetation. We recommended varieties Komerciyna, Smuglyanka, Zolotokolosa for growing under these conditions by grain productivity and varieties Komerciyna, Smuglyanka and Natalka by grain protein content and protein composition. Variability of agriculture-value traits between varieties was higher under slope conditions than on flat. Only variety Korisna was stable by protein composition under every condition. At the same time all varieties were depended on grows conditions (relief) to reach high level of grain yield. We cannot observe just the same by grain quality. We established that wheat grains contains more microelements than straw. At the same time the lead and nickel uptake was more in the straw samples. Thus, influence of relief on microelements and heavy metals content in the winter wheat grain and straw is not so high as for macroelements and, thus, for grain productivity and quality.

Genetic Components and Correlation Coefficient for Earliness and Grain Yield in Rice

The present research was conducted to study earliness and their correlations with grain yield in rice breeding. It was carried out during 2012 and 2013 growing seasons at RRTC Farm, Sakha, Kafr El-Sheikh, Egypt. F1 were evaluated along with their parents for genotypic variation. ANOVA revealed significant differences at the 0.01 level among crosses and parents as well as between parents and crosses. These results indicated a wide range of variations among parental groups. The mean squares of parents vs. crosses were found to be significant for all grain yield and its component characters. Variance among crosses indicated significant SCA effects at the 0.01 level for all its component traits. Concerning GCA effects four entries; Sakha 101, Novator, Anait and Large Stigma exhibited positive significant estimates at 0.01 levels for grain yield /plant. The desirable hybrid combinations Giza 179 X Large Stigma and Sakha 105 X VNIRB 572 exhibited significant values of SCA effects at 0.01 and 0.05 levels for grain yield. Heritability estimates in narrow sense ranged from low to moderate. Sakha 101 X Novator, Sakha 106 X Novator and Giza 179 X Large Stigma were the promising hybrid combinations for improving yield character according to results for mid and better parent heterosis. Positive significant correlation coefficient at 0.01 level was recorded between 1000-grain weight and grain yield/plant. The four earliness component traits understudy contributed directly to the earliness character. Also, the earliness component traits; days to heading, days to maturity and elongation of panicle initiation had a direct contribution to yield component.

Nitrogen use efficiency in spring wheat: genotypic variation and grain yield response under sandy soil conditions

SUMMARYAgricultural practices are likely to lower nitrogen (N) fertilization inputs for economic and ecological limitation reasons. The objective of the current study was to assess genotypic variation in nitrogen use efficiency (NUE) and related parameters of spring wheat (Triticum aestivumL.) as well as the relative grain yield performance under sandy soil conditions. A sub-set of 16 spring wheat genotypes was studied over 2 years at five N levels (0, 70, 140, 210 and 280 kg N/ha). Results indicated significant differences among genotypes and N levels for grain yield and yield components as well as NUE. Genotypes with high NUE exhibited higher plant biomass, grain and straw N concentration and grain yield than those with medium and low NUE. Utilization efficiency (grain-NUtE) was more important than uptake efficiency (total NUpE) in association with grain yield. Nitrogen supply was found to have a substantial effect on genotype; Line 6052 as well as Shandawel 1, Gemmiza 10, Gemmiza 12, Line 6078 and Line 6083 showed higher net assimilation rate, more productive tillers, increased number of spikes per unit area and grains per spike, extensive N concentration in grain and straw, heavier grains, higher biological yield and consequently maximized grain yield. The relative importance of NUE-associated parameters such as nitrogen agronomic efficiency, nitrogen physiological efficiency and apparent nitrogen recovery as potential targets in breeding programmes for increased NUE genotypes is also mentioned.

Microwave Synthesis of Fe2 O3 and ZnO Nanoparticles and Evaluation Its Application on Grain Iron and Zinc Concentrations of Wheat (Triticum aestivum L.) and their Relationships to Grain Yield

Fe2O3 and ZnO nanoparticles were synthesized by a fast microwave method. Nanostructures were characterized by X-ray diffraction and scanning electron microscopy. The goal of bio-fortification is to develop plants that have an increased content of bioavailable nutrients in their edible parts. The micronutrients magnesium (Mg), manganese (Mn) and copper (Cu), boron (B) and calcium (Ca) are essential for plants and the humans and animals that consume plants. Increasing the micronutrient density of staple crops, will greatly improve human nutrition on a global scale. In order to investigate the effect of Iron and Zinc on nutrient uptake of two line of wheat. The experimental design used for this research was a factorial experiment under complete randomized block design with three replications and two variety of wheat including Roshan back cross (V1) and C-78-14 line (V2), three levels of Iron from Fe-EDDHA (Sequestrene138) including no application (F0), Fe sulphate (F1) and Nano Fe2O3 (F2) and three Levels of Zinc as zinc sulphate (ZnSO4) including no application (Z0), 25 kg/ha-1 (Z1) and 50 kg/ha-1 (Z2) were used. The result is showed that application of nanoparticles increased the study of parameters such as magnesium, manganese, copper, boron and calcium. Highest levels of grain yield with 5.13 ton/ha-1 was obtained in C-78-14 variety.

Selection of inbred maize (Zea mays L.) progenies by topcrosses conducted in contrasting environments.

The aim of this study was to identify inbred progenies of S0:1 maize (Zea mays L.) plants that were efficient at a low level of technology and responsive at a high level of technology through the use of topcrosses. Two contrasting environments were created using two levels of base fertilization and topdressing, so that the levels of nitrogen, phosphorus, and potassium were applied four times higher in one environment than in the other. We used S0:1 progenies derived from commercial hybrids in topcrosses with two testers (an elite line from the flint heterotic group and an elite line from the dent heterotic group). The progenies and three controls were evaluated in an augmented block design in Nossa Senhora das Dores, SE, Brazil in the 2010 crop season. The average grain yield in the high-technological level was 21.44% greater than that in the low-technological level. There were no changes in progeny behavior in the two technological levels for grain yield. The testers did not differ in the average grain yield of the progenies at the two technological levels. Therefore, it is possible to select progenies derived from commercial hybrids that have an efficient response to fertilization.

Effect of Green Manures on Rice Growth and Plant Nutrients under Conventional and No‐Till Systems

Alfalfa (Medicago sativa L.) is a good green manure resource with high N and P concentrations, but its effect on rice (Oryza sativa L.) growth and plant nutrients has not been fully elucidated. Two green manure species, alfalfa and broad bean (Vicia faba L.), and two N fertilizer levels (0 and 200 kg ha−1), alone or in combination, were applied to rice paddy soil under conventional tillage (CT) and no‐till (NT) systems in 2010 and 2011. The results showed that, under CT, alfalfa had a more pronounced effect on increasing grain yield and nutrient content in the grain, plant (leaf N and leaf P), and soil (total N and Olsen P) than broad bean (p < 0.05). Compared with the N fertilizer treatment, the alfalfa treatment alone achieved statistically equivalent levels of grain yield but significantly increased P contents in grain and leaf and Olsen P in soil. The leaf P concentrations at the panicle and grain filling stages had significant positive direct effects and indirect effects via leaf N concentration on grain yield. The effect of alfalfa green manure on the supply of available P to rice was equal between CT and NT systems. The combined treatment of alfalfa and N fertilizer achieved the highest grain yield of all treatments, increasing the yield under CT by 8.58 and 8.21% compared with the N fertilizer treatment in 2010 and 2011, respectively. These results indicate that green manure with a high P concentration is capable of alleviating P deficiency in both CT and NT rice cultivation systems.

Potassium requirement in relation to grain yield and genotypic improvement of irrigated lowland rice in China

AbstractThe yield of rice (Oryza sativa L.) has increased substantially with the development of new cultivars, but the role of potassium (K) requirement for the increase in grain yield and the genotypic advance is still unclear. In order to investigate this relationship a database of 1199 on‐farm measurements (harvest index 0.4) comprising > 400 modern rice cultivars was collected during 2005–2010 across major irrigated lowland rice–production regions of China. This was used to evaluate the relationships among K requirement, grain yield, and genetic improvement. Across all the sites and seasons, mean reciprocal internal efficiency of K (RIE‐K, kg K [t grain produced]–1) was 19.8 kg K (t grain)–1 and rice yield averaged 8.7 t ha–1. Considering four levels of grain yield (< 7.5, 7.5–9, 9–10.5, and > 10.5 t ha–1), the respective RIEs were 18.7, 19.4, 20.5, and 21.7 kg K (t grain)–1. The gradual increase in the RIE‐K with yield was attributed mainly to the increase in straw and grain K concentration and the decrease in the K harvest index. The RIE‐K values for ordinary inbred, ordinary hybrid, and “super rice” were 18.5, 20.1, and 19.9 kg K (t grain)–1, respectively. Examining the historical development of rice cultivars, the RIE‐K decreased from 40.9 (Nanjing1, early tall, inbred) in the 1950s to 19.8 (IR24, semi‐dwarf, ordinary inbred) in the 1970s, and then increased to 20.9 (Shanyou63, modern ordinary hybrid) in the 1980s and 20.6 kg K (t grain)–1 (II‐you084, “super” rice) in the 2000s. This variation in RIE‐K among grain‐yield levels and cultivars highlights the importance of information on rice K requirement in calculating K balance and optimal K‐fertilizer rate for rice production.

Effects of climate change on water use efficiency in rain-fed plants

Water use efficiency (WUE) reflects the coupling of the carbon and water cycles and is an effective integral trait for assessing the responses of vegetated ecosystems to climate change. In this study, field experiments were performed to examine leaf WUE (WUEleaf) in response to changes in CO2 concentration and other environmental variables, including soil moisture and air temperature. We also used yield of maize and soybean, soil water content and precipitation data to calculate water use efficiency at the level of grain yield (WUEgrain) in a manner that enabled us to analyze the effects of climatic factors on WUEgrain. The results showed that the WUEleaf measurements of maize and soybean plants were negatively correlated with soil moisture and air temperature. At a photosynthetically active radiation (PAR) of 1.600 μmol m -2 s -1 , increasing ambient CO2 concentrations (from 400 to 800 μmol mol -1 ) improved WUEleaf by 52.0% and 75.8% for maize (a C4 species) and soybean (a C3 species), respectively. Increased annual precipitation stimulated maize WUEgrain up to levels of approximately 500-550 mm, although maize WUEgrain decreased when annual precipitation exceeded 550 mm. It appears that 400-450 mm is an economical evaportranspiration (ET) for spring maize in Chaoyang area of northeast China. For soybean, more water often reduces WUEgrain, and there is a linear relationship between changes in WUEgrain and changes in annual temperature. The different responses of WUEgrain and WUEleaf to climate change suggest that caution should be taken when attempting to up-scale WUE from leaf to grain or biomass levels.

Potencial genético de progênies de feijão-caupi segregantes quanto ao tipo da inflorescência

O objetivo deste trabalho foi avaliar o potencial genético produtivo de progênies de feijão-caupi (Vigna unguiculata) segregantes quanto ao tipo da inflorescência. Foram avaliadas 68 progênies F4 obtidas dos retrocruzamentos: (TV x 5058-09C x Cacheado-roxo) x TV x 5058-09C e (AU94-MOB-816 x Cacheado-roxo) x AU94-MOB-816, com os genitores. Dois experimentos foram conduzidos no delineamento de blocos ao acaso, tendo-se avaliado 17 progênies, com quatro repetições, em parcelas subdivididas quanto à inflorescência: simples e composta. A análise estatística foi realizada por modelos mistos via procedimento REML/BLUP. As estimativas das variâncias genéticas foram significativas para todos os caracteres estudados. Os caracteres comprimento do pedúnculo, número médio de vagens por pedúnculo e floração inicial apresentaram alta variabilidade e expressão do componente genético para a inflorescência composta. As progênies de inflorescência simples apresentam potencial genético produtivo similar às progênies de inflorescência composta. As progênies resultantes do retrocruzamento (AU94-MOB-816 x Cacheado-roxo) x AU94-MOB-816 são promissoras como estratégia para aumentar os níveis atuais de produtividade do feijão-caupi.

Identifying high yielding stable winter wheat genotypes for irrigated environments in Central and West Asia

Improved winter wheat (Triticum aes- tivum L.) cultivars are needed for the diverse environ- ments in Central and West Asia to improve rural livelihoods. This study was conducted to determine the performance of elite winter wheat breeding lines developed by the International Winter Wheat Improvement Program (IWWIP), to analyze their stability across diverse environments, and to identify superior genotypes that could be valuable for winter wheat improvement or varietal release. One hundred and one advanced winter wheat breeding lines and four check cultivars were tested over a 5-year period (2004-2008). Grain yield and agronomic traits were analyzed. Stability and genotypic superiority for grain yield were determined using genotype and geno- type 9 environment (GGE) biplot analysis. The experimental genotypes showed high levels of grain yield in each year, with mean values ranging from 3.9 to 6.7 t ha -1 . A set of 25 experimental genotypes was identified. These were either equal or superior to the best check based on their high mean yield and stability across environments as assessed by the GGE biplot analysis. The more stable high yielding genotypes were ID800994.W/Falke, Agri/Nac//Attila, ID8009 94W/Vee//F900K/3/Pony/Opata, AU//YT542/N10B/ 3/II8260/4/JI/Hys/5/Yunnat Esskiy/6/KS82W409/Spn and F130-L-1-12/MV12. The superior genotypes also had acceptable maturity, plant height and 1,000-kernel weight. Among the superior lines, Agri/Nac//Attila and Shark/F4105W2.1 have already been proposed for release in Kyrgyzstan and Georgia, respectively. The findings provide information on wide adaptation of the internationally important winter wheat genotypes, and demonstrate that the IWWIP program is enriching the germplasm base in the region with superior winter wheat genotypes to the benefit of national and international winter wheat improvement programs.

Diallelic analysis for lysine and oil contents in maize grains

Six S5 lines of maize, with differences for lysine and oil contents in grains, were used to carry out a complete series of diallelic crosses. The resulting 15 hybrids were grown in a field at two nitrogen levels (10 and 130 kg N ha-1). The general combining ability (GCA) and specific combining ability (SCA) were obtained by using the method 4, model I of Griffing for grain yield, and grain lysine and oil contents. Significant (p < 0.001) interaction was observed between GCA and N levels for grain yield, indicating the selection of different lines for each N level. This interaction was not significant for lysine content, but there were significant effects of GCA for this trait at both N levels (p < 0.1). Significant effects were not observed for GCA or SCA for oil content, however a positive correlation was observed between lysine and oil contents in the hybrids, in the lines and even in the control cultivars. The results indicate the effectiveness of selection for lysine content, irrespective of N level, in the studied non-opaque maize lines, and the possibility of achieving both high lysine and oil content in grains.

Site‐Specific Nitrogen and Plant Density Management in Irrigated Maize

Economic or environmental benefits resulting from variable‐rate (VR) application of N and seed are uncertain in irrigated maize (Zea mays L.) systems with high yield potential. We evaluated different plant population and N management strategies in two irrigated maize fields in Nebraska. Inputs were varied according to yield zones derived from yield maps, detailed maps of soil organic matter (SOM), and sampled seasonal NO3 status. Uniform management following Best Management Practices (BMPs) resulted in high levels of grain yield (>15 t ha−1 at Site 1; >12 t ha−1 at Site 2), nitrogen use efficiency (NUE), and gross return above input cost. Management of high‐yielding irrigated systems on relatively flat terrain was not improved through the predictive site‐specific approaches tested in this study, which relied on available historical field information (yield maps, weather) and seasonal soil sampling. Among four site‐years, only one site‐year showed significant increases in yield and NUE and decrease in N input with the VR N. Yield interactions between VR N management strategies and plant population were not significant. More potential for increasing yields, resource efficiency, and profitability may exist through integrating such approaches with dynamic, in‐season management of water and N. Such approaches are emerging, but remain to be evaluated thoroughly, particularly under high‐yielding conditions and against conventional BMPs.

Response of Chickpea Cultivars to Application of Boron in Boron‐Deficient Calcareous Soils

This study was conducted to investigate the effects of four boron (B) doses (control, 0 kg B ha−1; B1, 1 kg B ha−1; B2, 3 kg B ha−1; and B3, 6 kg B ha−1) in soils deficient in available B (0.19 mg B kg−1) and lime (CaCO3) content (20.7%) on yield and some yield components of five chickpea (Cicer arietinum L.) genotypes, namely Akçin‐91, Population, Gökçe, İzmir‐92, and Menemen‐92 in central Anatolian Turkey in the 2002 and 2003 growing seasons. Plant height, pods per plant, grain yield, protein content, protein yield, thousand seed weight, and leaf B concentration were measured. Grain yields in all genotypes (except for Gökçe) were significantly increased by 1 kg ha−1 B application. Application of 1 kg ha−1 B increased the yield by an average of 5%. Genotypes studied showed significant variations with respect to their responses to additional B. Akçin‐91 gave the highest grain yield (1704.8 kg ha−1) at 3 kg B ha−1, whereas Population, İzmir‐92, and Menemen‐92 yielded best (1468.2 kg ha−1, 1483.0 kg ha−1, and 1484.7 kg ha−1, respectively) at 1 kg B ha−1. Interestingly, Gökçe reached to the highest level of grain yield (1827.1 kg ha−1) at the control. Gökçe was a B deficiency B tolerance genotype. The other genotypes appeared to have high sensitivity to B deficiency. This study showed that B deficiency could result in significant yield losses in chickpea under the experimental conditions tested. Thus, B contents of soils for the cultivation of chickpea should be analyzed in advance to avoid yield losses.
