“…Increased in human population growth rate in Nigeria has lead into short fallow period. Continuous cultivation of crops on the same soil has also resulted in increased rate of rapid loss of soil fertility (Uzoh et al, 2015). This has necessitated the supplementing of soil natural fertility with fertilizers to replenish the soil for optimum yield.…”

Pre-planting analyses were performed to determine soil pH, particle size, organic matter, K, Na, P and S. Eight weeks after planting, maize parts above the soil level were harvested, oven-dried and dry-matter yield were computed and recorded. Application of S fertilizer appears not to be critical to maize production in the study areas since singly added S did not produce significant increase in biomass yield. In contrast, applied P significantly increased MDY in all the soils except Obantoko II, which already contained high amount of P sufficient for maize yield. Both synergism (Alabata II and III) and antagonistic (Alabata I) interactions were observed between P and S on MDY without any interactive effect in Obantoko I soil. Application rate of 30-45 kg P ha -1 with or without 10 or 20 kg S ha -1 resulted in significant effects on the MDY in the study areas. Field studies on effects of P and S on maize grain yield are recommended.

“…In crop rotations with legumes, the effect of soil nitrogen accumulation on subsequent crops has been reported to be highly variable (Walley et al, 2007;Anglade et al, 2015). One reason for the variation is that non-nitrogen (non-N) factors (such as the bio-physical change in soil properties due to legume residues, other plant nutrients, disease suppression, and weed control) contribute significantly to crop rotational benefits (Stevenson and Van Kessel, 1996;Arcand et al, 2014;Uzoh et al, 2017). In order to verify how the soybean varieties affect the yield of subsequent crops, it will be necessary not only to quantify the change in the soil nitrogen accumulation, but to also examine other bio-physical factors.…”

GIS-Based Analysis for UAV-Supported Field Experiments Reveals Soybean Traits Associated With Rotational Benefit

et al. 2021

Recent advances in unmanned aerial vehicle (UAV) remote sensing and image analysis provide large amounts of plant canopy data, but there is no method to integrate the large imagery datasets with the much smaller manually collected datasets. A simple geographic information system (GIS)-based analysis for a UAV-supported field study (GAUSS) analytical framework was developed to integrate these datasets. It has three steps: developing a model for predicting sample values from UAV imagery, field gridding and trait value prediction, and statistical testing of predicted values. A field cultivation experiment was conducted to examine the effectiveness of the GAUSS framework, using a soybean–wheat crop rotation as the model system Fourteen soybean cultivars and subsequently a single wheat cultivar were grown in the same field. The crop rotation benefits of the soybeans for wheat yield were examined using GAUSS. Combining manually sampled data (n = 143) and pixel-based UAV imagery indices produced a large amount of high-spatial-resolution predicted wheat yields (n = 8,756). Significant differences were detected among soybean cultivars in their effects on wheat yield, and soybean plant traits were associated with the increases. This is the first reported study that links traits of legume plants with rotational benefits to the subsequent crop. Although some limitations and challenges remain, the GAUSS approach can be applied to many types of field-based plant experimentation, and has potential for extensive use in future studies.

“…Since NPK rate of 150 kg ha -1 had been successfully used to grow varieties of non-leguminous cover crop in the study area (Oraegbunam et al, 2016), the lower rate here considered bambara's N-fixing ability. The rates of SSP and PM used here were adopted after Uzoh et al (2017) and Obi and Ebo (1995), respectively. Weeding was done by hand hoeing three weeks after sowing when earthening up was also done to cover roots exposed by rainfall.…”

Agricultural sustainability ensues when cultivation of field crops and associated techniques improve not just crop yields but also management-responsive soil properties. Bambara groundnut as an underutilized crop lacks research-based information on its agronomic requirements. This paper reports the key fertility indices of a loamy-sand soil in southeastern Nigeria as influenced by soil and agronomic management practices involving factorial combinations of two bambara groundnut varieties (Caro and Olokoro), two plant spacings (30 cm × 75 cm and 45 cm × 75 cm) and four organic/inorganic fertilizer options. These fertilizer options were NPK 15-15-15 (NPK), single super phosphate (SSP), poultry manure (PM) and Control. The plots under Caro variety spaced 30 cm × 75 cm and grown with NPK or SSP fertilizer showed the highest CEC (8.40 cmol kg–1) and exchangeable K (0.15 cmol kg–1), respectively. Olokoro variety spaced 45 cm × 75 cm and grown with PM or SSP gave the highest total nitrogen (0.14%), soil pHwater (6.35), available phosphorus (107.60 mg kg-1) and exchangeable Ca (3.70 cmol kg-1). The interactions plant spacing × fertilizer type and crop variety × fertilizer type affected all the soil fertility indices studied, while crop variety × plant spacing affected soil pHwater, available phosphorus, CEC and exchangeable Ca and Mg. Generally, as main factors, Olokoro variety, NPK and 45 cm × 75 cm improved soil properties better than their counterparts.
