“…The HL were significantly lower (-52%) when the machines worked in the sub-plots of density D1 (13ptm -2 ). This result highlights what has been stated by [27], who claim that planting density is a fundamental agronomic factor for successful harvesting.…”

“…Total losses from mechanized harvesting (HL), which result from the sum of total losses during the digging phase (DTL) and the separation phase (SL), were significantly lower (52%) when machines worked in sub-plots with density D 1 . This result reinforces what is stated by the authors of [25], who argue that planting density is a fundamental agronomic factor for good mechanized peanut harvesting efficiency in terms of product losses. The HL throughout the entire harvest, relative to the estimated production, was 11% for D 1 and 29% for D 2 .…”

The world production of peanuts is 45.9 million tons, of which China and India account for 50% of the total production. The cultivation of peanuts in Italy has had a reduction in recent decades mainly due to the high harvesting costs due to a lack of specific mechanization despite possessing favorable soil and climatic conditions. In this work, modern harvesting technologies are analyzed for adaptation to Italian areas and loss containment, and agronomic technique adaptation for mechanical harvesting. The mechanical harvesting was evaluated in two steps: plant extraction and separation pods. The results showed that lower planting density led to approximately 22% higher production and reduction in crop losses (−52%). The same trend showed that yield and harvesting efficiency were found to be 40% and 22% higher. Our research aimed to evaluate the impact of new technologies integrated by suitable agronomic management, grain losses, and the quality of the final product obtained. The lowest density also improved the healthy pod rate by 11%, from 59 to 70%. These results suggest that an integration of modern technologies and specific agronomic management improves pod retention during harvesting.

“…Despite its importance, the identification of peanut cultivars with high productivity and production stability that tolerate desiccation is still little studied. Therefore, studies on peanut seed desiccation are necessary (Gantait et al 2019). Given the above, this work aimed to evaluate the biochemical and physiological quality of peanut cultivar seeds under different periods of imbibition and drying.…”

The objective of this research was to evaluate the biochemical and physiological quality of peanut cultivar seeds under periods of imbibition and drying. A completely randomized statistical design was adopted, in factorial scheme, with four replications. The three peanut cultivars were: BR1, BRS 151-L7, and IAC 505. The imbibition and drying periods were: 0, 12, 24, 36 and 48 hours. The seeds were imbibition with the aid of germitest paper and distilled water, then dried on a metal screen in a plastic box with silica, according to the periods studied. Physiological variables were evaluated (percentage of germination, normal seedlings, abnormal seedlings in the first count and abnormal seedlings in the final count, accelerated aging, seedling length, electrical conductivity, speed index, and average germination time) and biochemical variables (sugar concentration total, reducing sugars, hydrogen peroxide, total superoxide dismutase proteins, and total proteins). The desiccation tolerance of peanut seeds is reduced as the period of water absorption followed by drying increases.Seeds of cultivar IAC 505 have greater tolerance to imbibition and subsequent desiccation compared to seeds of BR1 and BRS 151-L7.
