This research sought to minimize inorganic arsenic levels in polished rice grain by using different irrigation and phosphorous fertilization practices while also maintaining crop yield and water productivity. Two experiments were conducted during seasons 2018?2019 and 2019?2020 using a split-plot design with three blocks, five irrigation treatments (main-plots) and two phosphorous levels (sub-plots). Irrigation treatments consisted of a traditional continuous flood (CF) control and four alternatives irrigation techniques with one or two drying
events during the irrigation cycle. The phosphorous fertilization levels investigated were an unfertilized control (0 kg P2O5 ha− 1 ) and the recommended fertilization level of 50 kg P2O5 ha− 1 . Soil pH and redox potentials were measured in each treatment. Strategically-timed, low severity drying events were effective at achieving aerobic soil conditions, resulting in Eh values over 50 mV. The alternative irrigation treatment with two drying events, implemented at panicle initiation and full flowering, was the most effective in reducing inorganic arsenic in grain without affecting grain yield or the amount of irrigation water applied. This irrigation technique could be considered as an alternative management to the traditional continuous flooded to reach minimal inorganic arsenic accumulation in grain in order to attend special quality standards or specific market requirements. Accumulated inorganic arsenic in grain was below international maximum levels in all analyzed samples, with an average value of 0.084 mg kg− 1

ABSTRACT.- Fruit set of some apple cultivars is low despite abundant flowering. This could be, among other things, due to ethylene production of the flowers and or short ovule longevity. 'Minneiska' apple has been notable for its low productivity if not managed adequately. To better understand the cause of the low fruit set presented by this cultivar, a series of trials evaluating ethylene evolution and fruit set were conducted from 2017 to 2019. Flowers/fruitlets of different apple cultivars showed a distinct pattern in ethylene evolution. 'Minneiska' apple cultivar has a high and sustained level of ethylene just after bloom which may be the cause of the lower fruit set of 'Minneiska' compared to the other cultivars such as 'Gala' and 'Fuji'. The production and maximum peak of ethylene of 'Minneiska' flower/fruitlet clusters varied among years. Spray applications of aminoethoxyvinylglycine (AVG) during the bloom and petal fall timing reduced ethylene levels compared to the untreated control. Fruit set and fruit number per tree was also increased with the applications of AVG. © 2022 International Society for Horticultural Science. All rights reserved. |
