Enhancing food security through reducing Champa rice losses: Assessing the impact of crop moisture and harvesting methods on yield quantity and quality
Jamshid Kyani, Mahmoud Ghasemi-Nejad-Raeini, Afshin Marzban
TL;DR
This paper studies how harvesting methods and grain moisture affect rice losses and quality, aiming to improve food security.
Contribution
The study identifies optimal harvesting methods and moisture levels to minimize rice losses and maximize quality in Champa rice.
Findings
Manual harvesting at low moisture yields highest Head Rice Yield (86%) and lowest cracked grains (2.66%).
Grain combine harvesting at high moisture causes significant grain breakage (33.66%) and cracked grains (30.66%).
Rice combines at low moisture levels reduce paddy loss to 2.5%, significantly better than manual harvesting.
Abstract
Rice is a major staple crop globally, and minimizing harvest-stage losses is essential for improving production efficiency and food security. Among the critical factors in direct combine harvesting, the timing—determined by grain moisture content plays a crucial role in both yield quality and quantity. This study investigated the impact of harvesting methods and grain moisture levels on the quantitative and qualitative losses of Champa rice in Ramhormoz County during the 2019 growing season. A factorial experiment was conducted using a Randomized Complete Block Design (RCBD) with three replications. The factors included three grain moisture levels (13–15%, 23–25%, and 39–41%) and three harvesting methods (manual, rice combine, and grain combine). Results indicated that at low moisture levels, the highest paddy loss (9.53%) occurred with manual harvesting, while the rice combine recorded…
