The Decentralized Autonomous Government of the province of Chimborazo promotes the agricultural productive development of the province by promoting entrepreneurship, and improving the capacities of producers, access to production factors, and integration of actors and subjects of agriculture and management on the basis to strategic planning. The construction of the Chimborazo Competitiveness Agenda was a participatory process that identified opportunities to improve the agricultural sector, where agricultural production at the primary level was recognized as a vocation and strength of the province; however, a strategic necessity was to establish possibilities of adding value and diversifying agricultural production. The definition of a set of agricultural products with high potential at the primary level and/or in agroindustrial processes that are not deeply explored required determining market signals to identify new medium- and long-term commercial possibilities for Chimborazo farmers. Additionally, it was recognized that the management of the province of Chimborazo was based on its management of the Millennium Development Goals, the Constitution of the Republic, the National Plan for Development in a Supra-Provincial Framework, as well as the Plan Development of Chimborazo, the Territorial Planning Plan and others that promoted planning with a focus on territorial and solidarity sustainable development. Keywords: Chimborazo, productive development, entrepreneurship, agricultural sector. Resumen El Gobierno Autónomo Descentralizado de la Provincia de Chimborazo impulsa el fomento productivo agrícola de la provincia mediante la promoción del emprendimiento, el mejoramiento de las capacidades de los productores, acceso a factores de producción, integración de los actores y sujetos del agro y gestión en base a una planificación estratégica. Como parte de dicho accionar, la construcción de la Agenda de Competitividad Chimborazo fue un proceso participativo que identificó oportunidades para mejorar el sector agrícola, donde se reconoció la producción agrícola a nivel primario como una vocación y fortaleza de la provincia, no obstante, una necesidad estratégica fue el establecer posibilidades de agregación de valor y de diversificar la producción agrícola. La definición de un conjunto de productos agrícolas con alto potencial a nivel primario y/o en procesos agroindustriales que no están profundamente explorados requirió determinar señales de mercado para identificar posibilidades comerciales nuevas a mediano y largo plazo para los agricultores de Chimborazo. Adicionalmente, se reconoció que la gestión de la provincia de Chimborazo tuvo como base los Objetivos del Milenio, la Constitución de la República, el Plan Nacional de Desarrollo en un marco supra-provincial, así como el Plan de Desarrollo de Chimborazo, el Plan de Ordenamiento Territorial y otros en su conjunto que promovieron una planificación con un enfoque de desarrollo sostenible territorial y solidario. Palabras clave: Chimborazo, fomento productivo, emprendimiento, sector agrícola.

In tropical conservation agricultural systems, crop yield is limited by soil acidity and root-growth inhibition, especially under intensive crop rotation. This study evaluated the effect of surface applications of lime and phosphogypsum in improving soil fertility and crop yield in a tropical region. Four treatments were evaluated: control (without soil amendment); and application phosphogypsum (2.1 + 2.1 + 2.1 Mg ha–1), lime (2.7 + 2.0 + 2.0 Mg ha–1), and a combination of lime and phosphogypsum at the given rates, applied in 2002, 2004 and 2010, respectively. We evaluated the soil chemical properties, root development, plant nutrition, yield components and grain yield of 10 crops over 4 years using five species: maize (Zea mays), crambe (Crambe abyssinica), cowpea (Vigna unguiculata), wheat (Triticum aestivum) and common bean (Phaseolus vulgaris). Our long-term results demonstrate the benefits of surface liming in alleviating subsoil acidity, reducing Al3+ toxicity, improving availability of Ca2+ and Mg2+, and increasing accumulation of soil organic matter in all soil profiles at depths up to 0.60 m. For maize and crambe, adding phosphogypsum increased development of plants and reproductive structures, which increased grain yield. Phosphogypsum exhibited synergistic effects in association with lime for maize and common bean. Phosphogypsum did not have an effect on cowpea and wheat, whereas surface liming was essential to improve plant nutrition, grain yield and wheat grain quality. The combination of both soil amendments is an important tool to reduce the soil acidification process, resulting in the highest levels of Ca2+ and Mg2+ and the highest base-saturation values in the topsoil layers (0–0.20 m) over time. Our long-term results showed the viability of surface liming plus phosphogypsum for improving tropical soil fertility, which can reflect an increase in grain yield and contribute to the sustainability of agricultural systems under intensive land use in highly weathered areas.

The paper presents the results of studies of the effect of inorganic fertilizers on the structural indicators of Helianthus annuus crop yield in the western part of Azerbaijan. As a result of the studies carried out, it can be concluded that there was a positive effect when fertilizer application. So, there was an increase in the diameter of the basket by 0.8–2.3 cm, the number of achenes in the basket — 54.7–204.6 pcs, the mass of seeds in the basket — 5.5–24.1 g, and an increase in the mass of 1000 seeds — by 3.5–13.7 g in comparison with the non-fertilizer control. To obtain a high and high-quality sunflower seed yield and restore soil fertility on the irrigated chestnut soils of the Ganja-Gazakh zone, it is recommended that farms use inorganic fertilizers annually at the N120P120K120.

Maize production in Malawi is limited mainly by low soil N and P. Improved fallows of N-fixing legumes such asTephrosiaandSesbaniaoffer options for improving soil fertility particularly N supply. The interactions ofTephrosiafallows and inorganic fertilizers on soil properties, N uptake, and maize yields were evaluated at Chitedze Research Station in Malawi. The results indicated that the level of organic matter and pH increased in all the treatments except for the control. Total N remained almost unchanged while available P decreased in all plots amended withT. vogeliibut increased inT. candidaplots where inorganic P was applied. Exchangeable K increased in all the plots irrespective of the type of amendment. The interaction of N and P fertilizers withT. vogeliifallows significantly increased the grain yield. The treatment that received 45 kg N ha−1and 20 kg P ha−1produced significantly higher grain yields (6.8 t ha−1) than all the other treatments except where 68 kg N ha−1and 30 kg P ha−1were applied which gave 6.5 t ha−1of maize grain.T. candidafallows alone or in combination with N and P fertilizers did not significantly affect grain yield. However,T. candidafallows alone can raise maize grain yield by 300% over the no-input control. Based on these results we conclude that high quality residues such asT. candidaandT. vogeliican be used as sources of nutrients to improve crop yields and soil fertility in N-limited soils. However, inorganic P fertilizer is needed due to the low soil available P levels.

Winter rye is of great importance in strengthening and developing the grain economy of the Non-Chernozem region of Russia. In recent years, due to the high cost of fertilizers and plant protection products, agricultural producers have begun to pay more attention to the biologization of agriculture. One of the main means of biologizing agriculture is the use of sideration. The article presents the results of the research on the influence of pure, green-manured and occupied fallows on the growth and development of winter rye, crop contamination, soil microbiological activity and grain yield in the eastern part of the Volga- Vyatka zone. It was revealed that the weather conditions of the growing season of the Republic of Mari El allowed the cultivation of winter rye on the green-manured fallow. With timely plowing of siderite, the amount of productive moisture in the soil before sowing winter crops is sufficient. The use of sideration improves the phytosanitary state of the agrocenosis – the contamination of winter rye crops when cultivated with green-manured fallow is significantly lower in comparison with cultivation with occupied fallow. Being a valuable food and energy material for the soil microflora, the plowed organic mass of green fertilizers contributes to a significant increase in the microbiological activity of the soil. The replacement of pure and occupied fallow with green-manured fallow cultivation of winter rye on this fallow allows you to get a significant increase in grain yield.

A field study was conducted to analyze the effect of long term use of organic and inorganic fertilizers on productivity and soil fertility under paddy-sesame cropping system. Application of 100% NPK + secondary and micro-nutrients based on soil test (T7) showed significantly higher mean grain yield of paddy (4735 kg/ha) and sesame (460 kg/ha) and rice equivalent yield (5348 kg/ha) followed by application of 50% NPK + 50% N as Farmyard manure (FYM) + inorganic source of micronutrients as per soil test (T1). Whereas, application of 50% recommended dose of nitrogen (RDN) through FYM + bio-fertilizers for N + Recommended dose of phosphorus (RDP) through rock phosphate + phosphorus solubalizing bacteria (PSB) showed significantly least mean grain yield of paddy (3209 kg/ha) and sesame (314 kg/ha) and rice equivalent yield (3628 kg/ha). Further, among organic treatments (T2 to T6), higher mean grain yield of paddy (3834 kg/ha), sesame (326 kg/ha) and rice equivalent yield (4269 kg/ha) as compared to other treatments was recorded following the application of one third of RDN through FYM + one third of RDN through vermicompost + one third of RDN through neem cake + bio-fertilizers containing N and P carriers (T6). Whereas, higher nutrient status with respect to major and micronutrients and the improved soil fertility status was recorded in organic treatment plots. The application of nutrients through organic sources would improve the soil fertility status under paddy-sesame cropping system.

Due to the complexity of the relief of Mountain Shirvan, the dominant gray-brown soils, subject to varying degrees of erosion, have lost their fertility. To restore and maintain of these soil fertility, vermicompost and inorganic fertilizers were introduced under winter barley in various versions. It was revealed that the highest crop yield falls on the option of 6 tons of vermicompost per hectare. In this variant, the length of the ear of barley was 11.2 cm, the number of grains was 33, the weight of grains from 1 m2 was 183.6 g and the weight of 1000 grains was 44.7 g. 10–15% with the option of inorganic fertilizers. In this connection, the widespread use of vermicompost is considered expedient both from an economic and an ecological point of view.

Soil fertility determines a plant's development process that guarantees food sufficiency and the security of lives and properties through bumper harvests. The fertility of soil varies according to regions, thereby determining the type of crops to be planted. However, there is no repository or any source of information about the fertility of the soil in any region in Nigeria especially the Northwest of the country. The only available information is soil samples with their attributes which gives little or no information to the average farmer. This has affected crop yield in all the regions, more particularly the Northwest region, thus resulting in lower food production.  Therefore, this study is aimed at classifying soil data based on their fertility in the Northwest region of Nigeria using R programming. Data were obtained from the department of soil science from Ahmadu Bello University, Zaria. The data contain 400 soil samples containing 13 attributes. The relationship between soil attributes was observed based on the data. K-means clustering algorithm was employed in analyzing soil fertility clusters. Four clusters were identified with cluster 1 having the highest fertility, followed by 2 and the fertility decreases with an increasing number of clusters. The identification of the most fertile clusters will guide farmers on where best to concentrate on when planting their crops in order to improve productivity and crop yield.
