Calibration and Validation of Aquacrop for Hot Pepper (Legon 18) Irrigation | Chapter 6 | Research Advances and Challenges in Agricultural Sciences Vol. 1

This paper presents the verdicts of a study that aimed to measure and test the performance of AquaCrop in envisioning crop yield and seasonal water necessities for hot pepper (Legon 18) education in a tropical moist coastal grassland zone in on west side when facing north-central Ghana (Capote Coast). The study examined four situations: T1 (100% ETc), T2 (90% ETc), T3 (80% ETc), and T4 (70% ETc). While AquaCrop was unable to correctly simulate the yield of hot red pepper (Legon 18) for all treatments, it acted show a low departure of 4% for Treatment T2. Nevertheless, the model was able to correctly predict the migratory water requirements for two together experiments. It should be famous that the calibration of AquaCrop was hindered by a lack of dossier on crop canopy cover, that is a crucial limit in the model's development.

Study on Sprinkler Irrigation and Soil Tillage Practices in Sugarcane Plantations as Influenced by Soil Texture and Water Storage in Northern Ivory Coast | Chapter 1 | Current Topics in Agricultural Sciences Vol. 1

To estimate soil texture and water storage capacity for sprinkler irrigation and tillage management, soil surveys were conducted in the Ferké 1 and Ferké 2 sugar mill plantations in northern Ivory Coast. In Ferké 1, a 5-year observation experiment comparing reduced tillage to conventional tillage over a 28-hectare irrigated cane crop was also undertaken for yield optimization. After harvest or before to replanting, soil samples were taken at five different locations along two transects in each sugarcane field, which covered around 30-40 hectares and had 432 m long cane rows, yielding an average soil sample of 1.5-2 kg. The sugar company's soil laboratory measured physical parameters such as texture and water retention curves. The bulk of the soils tested were coarse-textured, with a lower to medium water storage capacity (70-89 mm) across 60 cm depth, corresponding to readily available moisture less than 60 mm in Ferké 1 and 85 percent in Ferké 2. Over four cropping seasons, no significant difference in cane yields due to tillage practises was seen, with the exception of the sugarcane plant crop. In comparison to decreased tillage (+3 t/ha), the yield decline from plant cane to first ratoon was quite considerable under conventional tillage (-16 t/ha). When compared to conventional tillage (83 t/ha), the second ratoon yielded even more cane (89 t/ha).
