Combining the UAV-Based Multispectral Imaging and the Variable-rate Nitrogen Application in Wheat-growing in Obtaining Wheat Yield
Vol.2(2); Pages:1-9. Published on September 2025
Abstract
The situation-specific and timely nitrogen (N) management is relevant to maximizing the productivity of wheat and reducing environmental losses of nitrogen at the same time. In this analysis, a filter pipeline (of multispectral imagery based on an unmanned aerial vehicle (UAV) and variable-rate nitrogen application (VRNA) is tested in order to optimize nitrogen (N) allocation in spring wheat (Triticum aestivum L.). NDVI and red-edge maps were produced as a result of UAV flights carried at tillering and early booting stages and subsequently transformed into N-recommendation zones with the assistance of a calibrated vegetation indexyield response model. The use of VRNA took place using the GPS device-enabled piece of fertilizer spreader in 32 hectares in the Central Jutland region of Denmark with sticky N rates to reach farmer-practice in the neighboring plots. Measures of grain yield, grain protein and apparent nitrogen-use efficiency (NUE) were taken at harvest. There was 7.8 percent greater yield and 14.2 percent higher NUE on VRNA plots than on uniform treatment (p < 0.05), and no significant effects on overcoming protein content in grains. Moreover, VRNA treatment lowered the levels of total N input by 11 percent. These results support the benefit of UAV remote sensing in agronomic and environmental aspects of variable-rate management of nutrients in wheat cropping systems using decision-support algorithms. The same workflow can be applied to agro-ecologies in which other cereal species grow and is compatible with objectives of data-driven intensification and sustainability in contemporary farming.

Biostimulants based on extracts of seaweed as a means of improving Drought Tolerance in Maize grown under semi-arid conditions
Vol.2(2); Pages:10-18. Published on October 2025
Abstract
Biostimulants based on seaweed have turned out to be a potentially useful method of improving the capacity of crops to resist stress particularly during the event of drought. This was a field based study aimed at assessing the physiological and agronomic performance of maize (Zea mays L.) fertilized with seaweed extracts twice in two consecutive dry seasons in Ethiopia. The treatments involved control, single, and two applications of seaweed extract done at the times of the maize V6 stage and the tasseling stage. The findings informed major gains in chlorophyll content, relative water content, and stomatal conductance in treated plants. There was a 18.6 and 22.1 increased grain yield and water-use efficiency respectively (p < 0.05). These results indicate that seaweeds extracts may be an economical biostimulant that can be applied to enhance drought tolerance and water-use efficiency in rain-fed maize systems which could be beneficial in water-dependent regions that tend to experience water scarcity and drought stress.

Biochar Amendment of Composts in the Enhancement of Soil Health and Organic Tomato Farming Output
Vol.2(2); Pages:19-28. Published on October 2025
Abstract
The paper addresses the effects of prepared biochar-amended compost on soil health and tomato production in a Canary Islands organic agricultural machine. Three treatments were applied; compost without biochar, compost + 5% biochar and compost + 10 % biochar. Assessment of soil health was done in terms of optimal microbial biomass, pH, cation exchange capacity (CEC) and the yield of fruit. The results indicated that an application of 10% biochar treatment positively influenced the biological activity of the soil (p<0.01) and resulted in higher yield of tomatoes (21 percent). Biochar addition particularly at the added higher concentrations increased microbial activity and retention of nutrients giving a synergistic effect with the compost. This paper indicates the possibility of biochar-amended compost at promoting soil quality and yield in organic vegetable production, and it provides a promising approach to increasing an organic agriculture sustainability and production.

Measuring Pollinator Diversity and Crop Yield as Sunflower Agroecosystem Bordered Designs
Vol.2(2); Pages:29-36. Published on November 2025
Abstract
There are threats of pollinator decline, which pose a concern to crops productivity especially on insect pollinated plants such as sun flower (Helianthus annuus L.). In this research, the effect of diverse sources of floral borders on pollinator diversity and sunflower production in the 12 farms in southern Spain was gauged. The three types of border were the native wildflowers mix, the commercial pollinator mix and monoculture strips. The pollinator richness was greatest in naturally occurring wildflower borders (25 species) and visit the greatest with the significant 13.4 percent additional sunflower yield than fields without a single border (p < 0.05). Commercial mixtures gave moderate pollinator effects and monoculture strips supported fewer species and low pollinator visitation rates. These findings under-scored the necessity of agroecosystem floral diversification, with the indicators demonstrating that wildflower borders with native flora not only increase pollinator diversity, but that they also increase crop yields considerably. The results highlight the prospects of involving floral diversity into the management of farms as a feasible and cost-containable approach to enhancing pollination services and promoting the results of crops.

Monitoring Rice Leaf Blast in Paddy with Hyperspectral Vegetation Indices in Paddy Fields with the Help of Remote Sensing
Vol.2(2); Pages:37-42. Published on November 2025
Abstract
Rice leaf blast (Pyricularia oryzae) should be detected early to minimize fungicide overuse to prevent the losses of production. The paper involved the use of hyperspectral imagery methods to identify and delineate severity of rice blast in paddy fields of Shiga Prefecture in Japan. Photochemical Reflectance Index (PRI) Normalization Difference Red Edge (NDRE) and Modified Chlorophyll Absorption Ratio Index (MCARI) are all narrow-band vegetation indices which were analyzed in reference to scales of disease severity. The highest correlation between the field-observed disease incidence was with PRI and NDRE (R 2 > 0.85). Validity of the spatial distribution of the disease hotspots was confirmed with drone imagery and field sampling, which justified the viability of hyperspectral sensing to target effective disease mapping. The results reveal that hyperspectral imaging, especially vegetation indices offer a scalable and accurate rice disease surveillance protocol allowing early prediction of disease incidence and effective management having the capacity to enhance crop yield and decrease over reliance on fungicides.
