Emergence, Growth and Production of Sesame Under Salt Stress and Proportions of Nitrate and Ammonium

Abstract: -In arid and semi-arid regions, the quality of irrigation water varies in geographic terms and during the year, and the occurrence of water with high concentrations of salts is common. In this context, this study aimed to evaluate the emergence, growth and production of sesame, cultivar CNPA G3, irrigated with saline water and fertilized with N of different carrier proportions by the ratio of nitrate and ammonium (NO 3 --N and NH 4 + -N) in an experiment conducted in lysimeters arranged in a greenhouse in the … Show more

“…In general, the seed yield of all genotypes was affected by salinity conditions. The adverse effects of poor irrigation water quality on genotypes are evident may be due to the inhibition some of biochemical, and physiological processes, and ion imbalance (Dias et al, 2017;Shahid et al, 2020). In addition, the line's ability to absorb nitrogen is reduced under salinity conditions (Saha et al, 2015).…”

“…Trên thế giới, nhiều nghiên cứu sử dụng nước mặn tưới cho cây trồng đã được công bố (Beltrasn, 1999;Kim et al, 2016). Sử dụng nước mặn tưới cho cây trồng ở nồng độ cao, thời gian tưới mặn cũng như số lần tưới làm giảm sinh trưởng, phát triển và năng suất cây trồng vì gây mất nước do sự chênh lệch áp suất thẩm thấu giữa dung dịch đất và tế bào rễ (Flowers, 2004;Dias et al, 2017). Mặn ảnh hưởng đến hầu hết các giai đoạn sinh trưởng của cây (Nawaz et al, 2010).…”

“…Salt stress induced NH 4 + accumulation has been associated to the inactivation of specific enzymes involved in NH 4 + homeostasis [3,18], including glutamine synthetase (GS) and glutamate dehydrogenase (GDH) which can maintain NH 4 + cellular concentrations below toxicity levels by incorporating it into amino acids [22,23]. It has also been reported that NH 4 + fertilization in both Populus simonii and Sesamum indicum worsens the detrimental effects of salt stress on physiological and growth parameters, which indicates that high NH 4 + under salinity does not help plants cope with salinity [24,25]. Despite this, NH 4 + nutrition has been reported to enhance salt tolerance in citrus plants [26], Spartina alterniflora [27] and other wetland plants [28].…”
