Opis:
In Morocco, agriculture is an important sector that contributes to the country’s economy and food security. Accurately predicting crop yields is crucial for farmers, policy makers, and other stakeholders to make informed decisions regarding resource allocation and food security. This paper investigates the potential of Machine Learning algorithms for improving the accuracy of crop yield predictions in Morocco. The study examines various factors that affect crop yields, including weather patterns, soil moisture levels, and rainfall, and how these factors can be incorporated into Machine Learning models. The performance of different algorithms, including Decision Trees, Random Forests, and Neural Networks, is evaluated and compared to traditional statistical models used for crop prediction. The study demonstrated that the Machine Learning algorithms outperformed the Statistical models in predicting crop yields. Specifically, the Machine Learning algorithms achieved mean squared error values between 0.10 and 0.23 and coefficient of determination values ranging from 0.78 to 0.90, while the Statistical models had mean squared error values ranging from 0.16 to 0.24 and coefficient of determination values ranging from 0.76 to 0.84. The Feed Forward Artificial Neural Network algorithm had the lowest mean squared error value (0.10) and the highest R² value (0.90), indicating that it performed the best among the three Machine Learning algorithms. These results suggest that Machine Learning algorithms can significantly improve the accuracy of crop yield predictions in Morocco, potentially leading to improved food security and optimized resource allocation for farmers.

Opis:
Satellite-based irrigation performance is a valuable tool for improving yields in irrigated areas across the world and requires adequate land for long-term development. This study aimed to increase irrigation performance and yield gap variation of rainfed crops using the database of FAO’s Water Productivity Open Access Portal (WaPOR) and the Global Yield Gap Atlas. The evapotranspiration (ET) performance of irrigation is expressed in equity (CV of ET), reliability, adequacy (CV of ET), and water productivity (kg∙m-3). The rainfed crops are interpreted in terms of metric tonnes/ha. Specifically, 20,325 km2 of suitable pastoral land across eight sub-classes was converted to rainfed rice, sugarcane, maize, and vegetable crops. Results showed that the R2 value was 0.97 at Baro Itang and -0.99 at Sor Metu, with the Baro Gambella sub-catchment having the largest yield gap of 4.435.2, 8.870.4, and 10.080∙106 kg when the yield increased by 1/3, 2/3, and 3/4. On the other hand, Gumero Gore had the smallest yield gap of 10,690, 29,700, and 33,750 kg, respectively. The management regime was 2.87, 0.87, and 0.35 kg∙m-3 for growers in the estate, farmer association, and individual, respectively. The study concludes that no single irrigation technique can be considered the best, and a thorough analysis of spatiotemporal variation of the irrigation performance indicators and the yield gap in the water-scarce lower Baro watershed is required.

Opis:
Straw, particularly cereal straw, is a valuable by-product of crop production, which can be used for various purposes, e.g. as livestock feed and bedding or for making fuels, however it should primarily be retained on farmland in order to prevent soil organic matter (SOM) losses and thus to maintain or improve soil quality. The aim of this study was to analyze effects of the frequency of crop residues (straw) incorporation into the soil on the content of soil organic matter and on crop yields. There were the following experimental treatments: SR - straw of all crop in the rotation removed, S1 - straw of one crop per rotation incorporated, S2 - straw of two crops in the rotation incorporated, and S3 - straw of three crops incorporated into the soil (loamy sand). After 21 years of crop rotation with straw removal (SR) the SOM level in the soil slightly decreased to 14.4 g∙kg-1 soil DM, compared to that in 1997 (14.6 g∙kg-1). However, when straw of one crop (rape) per rotation was incorporated (S1) the content of SOM increased to 15.0 g∙kg-1 soil DM, and to 15.6 and 16.0 g∙kg-1 in S2 and S3 treatments, respectively. Straw retention had also a beneficial effect on the content of labile fractions of SOM (hot water extractable C and N). Grain yields and yield components of wheat and triticale, and seed yields of rape in the SR treatment were not significantly different from those obtained in S1, S2 and S3 treatments.

The objective of this study is to recover sludge from the Dar Gueddari sewage treatment plant and use it in the cultivation of corn in the open field on clay soil. To do this, four doses were tested against two types of controls: a control without addition of sludge and another with the addition of nitrogen-based fertilisers (200 kg N, 100 kg P and 100 kg K). The short-term effects indicated that the application of the sludge had a beneficial effect on the fertilising qualities of the soil and therefore on the crop yield. The monitoring of the agronomic parameters of the maize plant showed that the growths and the yields varied according to doses of the sludge. In grain yield, the difference between plot E4 and E0 was around 3.3 Mg∙ha-1. In addition, the plots treated with large sludge doses experienced improvements in total nitrogen and organic matter. During the second season, the results obtained showed decrease in nutrients (nitrogen and phosphorus). It emerged from the C:N ratio which was <8. This indicated a good mineralisation of the organic matter (OM) which was average of 2.48 ±0.04% and 2.5 ±0.01%, respectively in the E4 and E5 treatments. In addition, the amounts of N, P and Ca in dry matter (DM) increased with increasing the dose of sludge. During the 2017 season, the highest values were detected in plot E5 with averages of 1.6% in N and 0.53% in P.

Opis:
In this research, estimation potential of Aquacrop model under deficit irrigation and salinity conditions were evaluated for winter wheat grown under arid and semi-arid climates. Five different irrigation strategies and irrigation water salinity levels (0.5, 5, 7.5, 10, 15 dS m-1 ) were taken with the model to estimate deficit irrigation and salinity scenarios. Wheat grain yield, biomass production and canopy cover were simulated under deficit and salinity stresses. According to estimation of the model; the deficit irrigation with water reduction of more than 75 % of full irrigation was applied at growth stages of wheat, revealed the significant reduction in grain yield, biomass and canopy cover as compared with full irrigation practice. The increase in irrigation water salinity caused a significant decrease in grain yield and biomass value. It was compared to the 0.5 dS m-1 salinity level, a low value of 3% was obtained for the 5 dS m-1 salinity level. Yield loss of 7.5, 10 and 15 dS m-1 salinity levels were found to be 18.97%, 42.5% and 85.6% respectively. Also, increasing irrigation water depth in saline treatments resulted in increased grain and biomass yield. For sustainable water management in agriculture area, using simulation model such as Aquacrop is useful tolls to estimate effect of applied water depth and quality of irrigation water on crop yield.

Opis:
The COVID-19 outbreak has seriously affected the global food security at a time when it was significantly compromised by the effects of climate change and armed conflicts. The impact of the pandemic and quarantine restrictions imposed in response to the deadly virus brought humanity face-to-face with a new threat – that of food insecurity – which contributed to a high social demand for state-of-the-art methods of improving the cereal production efficiency. The aim of the study is to develop and implement a methodological approach to enhancing the cereal production efficiency. The methodology of the study relies on time series that made it possible to determine the main trends in regional cereal production and make projections. Application of the suggested approach in the Kostanay region revealed that this region was among the key cereal producers in the country. In 2019, the region was affected by extreme weather, which caused a sharp decline in cereal production. The present study, however, projects large opportunities for cereal production growth in the region and a significant increase in cereal production in the future. In addition, the paper suggests the following action plan to improve efficiency of the cereal production sector in the Kostanay region: streamlining of state support arrangements for cereal producers; development of affordable crop insurance products; systemic steps to increase cereal yields; development of logistic infrastructure; comprehensive monitoring of cereal production to develop a system of rapid response to changes in the external environment.

Opis:
This report presents an analysis of productivity trends in a suburban beet-producing region impacted by the loss of agricultural land by land claims. The analysis was conducted in the model cadastral locality of Dolní Heršpice. In order to calculate the potential production of agricultural crops, the authors selected one sowing structure that has been applied starting from 1950 until present. The choice of particular crop succession was based on the exemplary sowing structure for beet-producing regions provided by the Central Institute for Supervising and Testing in Agriculture. The calculation of the potential production of agricultural crops was divided into three time intervals, 1950-1990, 1990-2006, and 2006-2019. In the period from 1950 to 2019, the studied locality underwent a loss of arable land of 145.19 ha. The yield in a particular time interval was derived from the selected sowing procedure and subsequently recalculated to the surface area of the lost arable land. The results show that in the time interval 1950-1990, the produced agricultural crops could have reached a total of 26,975.28 tons. In the period 1990-2006, the yield of crops could be 5,598.85 tons, and in the period 2006-2019, a total of 8,423.6 tons of agricultural crops could have been achieved in the studied locality. The total yield for the entire monitored period could represent 40,997.50 tons of agricultural crops. The productivity by hectare oriented cultivation in all the monitored time intervals to prevailing sugar beet and potatoes. The analysis was compared with the statistical data on the development of sowing areas, production and yields of the monitored crops in the Czech Republic. The presented study documents the trend of arable land loss and potential threat of insufficient production, particularly in the case of strategic commodities such as sugar beet in beet-producing regions.

Opis:
The aim of the article is to estimate the impact of reducing the consumption of mineral fertilizers resulting from the New Green Deal assumptions on the yields of major crops in the 2030 perspective. The material for analysis was statistical data from the CSO and FAO. The collected data was processed dynamically by using trend analyzes and Pearson linear correlation. Maintaining the current trend of increasing the dose of NPK mineral fertilization will allow the use of crop production potential in Poland. On the other hand, the introduction of the NGD assumptions may result in a stagnation of crop yield at the current level. However, in relation to the scenario assuming the continuation of the current upward trend, these yields will be much lower. Reducing mineral fertilization introduced by means of an administrative decision without taking the principles of rational management of fertilizer components into consideration may have negative environmental consequences.
Celem pracy jest oszacowanie wpływu ograniczenia zużycia nawozów mineralnych, wynikających z założeń Nowego Zielonego Ładu, na plony głównych roślin uprawnych w perspektywie 2030 roku. Materiały do analizy stanowiły dane statystyczne GUS i FAO. Zebrane dane były przetwarzane dynamicznie przy użyciu analizy trendów i korelacji liniowej Pearsona. Na podstawie przeprowadzonych analiz wykazano, że utrzymanie obecnego trendu zwiększania dawki nawożenia mineralnego NPK pozwoli na wykorzystanie potencjału produkcji roślinnej w Polsce. Z drugiej strony, wprowadzenie założeń NGD może skutkować stagnacją plonów na obecnym poziomie. Jednak w stosunku do scenariusza zakładającego kontynuację obecnego trendu wzrostowego, plony te będą znacznie niższe. Ponadto ograniczenie nawożenia mineralnego, wprowadzone decyzją administracyjną, bez uwzględnienia zasad racjonalnej gospodarki składnikami pokarmowymi może nieść za sobą negatywne skutki środowiskowe.

The article presents the results of research that demonstrate the effectiveness of the proposed agro-technological measures of growing spring barley in the eastern part of the Northern Steppe of Ukraine. For the first time the regularities of growth, development and formation the grain productivity of plants of different varieties of spring barley and their adaptive indicators under the influence of biotic and abiotic factors are established. The reaction of plants of different varieties of spring barley to predecessors, mineral fertilizers, use of growth regulators in the conditions of the eastern part of the Northern Steppe for grain formation with appropriate grain quality indicators has been established. By investigation the genetic material that would stabilize the grain productivity of spring barley in the area of the eastern part of the Northern Steppe, a variety of spring barley Skhidnyi and the first brewing variety of spring barley Stepovik was bred. Regardless of the fact that the Northern Steppe is not a typical area for growing malting barley, however, the use of the proposed elements of technology contributes to the production of grain of appropriate quality. An additional impact on the quality of grain products is provided by the use of varieties of the appropriate purpose. Thus, by the using the improved growing technology of spring barley variety Stepovyk the protein content decreased to 10,1%, and the extractivity oppositely, increased to 75,9%. It is revealed that the introduction of the proposed elements of the growing technology of spring barley helps to strengthen the immunity of plants to pathogens of major diseases. As a result of research, new and improved existing methods of varietal technology for growing spring barley, which, in the conditions of the eastern part of the Northern Steppe, contribute to a more complete realization of the genetic potential of varieties, increase yields, improve grain quality and reduce production costs.
В статье приведены теоретическое обобщение и новое решение научной задачи, которая заключается в научном обосновании и разработке агротехнологических мероприятий повышения зерновой продуктивности растений ячменя ярового с учетом морфобиологических особенностей сортов, их реакции на предшественники, применение рострегулирующих препаратов и минеральных удобрений. По результатам экспериментальных исследований установлено, что применение агротехнологических приемов при выращивании ячменя ярового способствует улучшению таких биометрических показателей как: количество узловых корней, высота растений, общая и продуктивная кустистость, а, следовательно, и обеспечения оптимальной плотности продуктивного стеблестоя в посеве. Повышение показателей элементов структуры урожая зерна закономерно способствовало увеличению уровня зерновой продуктивности культуры. Так, при сравнении влияния предшественников между собой, было установлено, что урожайность зерна ячменя ярового наивысшей была после гороха, превышая аналогичные показатели, полученные после предшественника подсолнечник на 0,15 т/га. Установлено, что использование в технологическом процессе сорта Степовык, генетически предрасположенного к получению зерна пивоваренного качества, способствует формированию следующих показателей: масса 1000 – 54,0 г, содержания белка – 10,1%, экстрактивность – 75,9%. В результате исследований разработаны новые и усовершенствованы существующие приемы сортовой технологии выращивания ячменя ярового, которые в условиях восточной части Северной Степи способствуют более полной реализации генетического потенциала сортов, увеличивают урожайность, улучшают качество зерна и снижают производственные затраты.

Opis:
In order to evaluate the ability of the crop water stress index to estimate grain yield and water productivity of maize and black gram in the climatic conditions of Urmia (Iran), research was conducted under the conditions of single-row drip irrigation. This study was conducted in a randomized complete block design with four irrigation levels including 50 (I1), 75 (I2), 100 (I3) and 125 (I4) percent of the water requirements of the plants with three replications. The mean crop water stress index values for the I1, I2 and I3 treatments were 0.53, 0.44, and 0.28, respectively during the growth period of maize, and 0.37, 0.23, and 0.15 for black gram, respectively. In the present study, the correlation between the crop water stress index and the grain yield and also the water productivity of maize and black gram was high. According to the results, the highest grain yield for maize and black gram was obtained at crop water stress index values of 0.28 and 0.15, respectively. Therefore, these values are recommended for the irrigation scheduling of the plants. It should be noted that the maximum water productivity index for maize and black gram was obtained at crop water stress index values of 0.44 (I2) and 0.37 (I1), respectively, which are the values recommended for irrigation scheduling under restricted access to water.
