Case Study

Effects of Potassium Thiosulfate on Growth and Productivity of Faba Bean Plants

Emam S M, et al. Archives of Agriculture and Environmental Sciences, 2020, 5(2), 89-96.

Potassium thiosulfate (KTS) contains 25% K2O and 17% S and can be applied by drip, sprinkler or flood irrigation and as a foliar treatment. The study evaluated the effects of KTS and Amcoton (a mixture of 0.45% naphthylacetic acid and 1.25% naphthylacetamide) on the growth and productivity of three faba bean varieties. The results showed that Amcoton and/or KTS significantly increased growth index (e.g., plant height, number of leaves and branches, leaf area, shoot dry weight), yield components, chlorophyll content and photosynthetic efficiency compared to untreated control plants.
Treatment of plants with Amcoton/KTS
· Amcotone and/or KTS foliar application was performed at 35 and 50 days after sowing (DAS). The sub-plots area was 10.5 m2 (3.0 × 3.5 m) and contained 5 ridges 60 cm in width.
· Experiment comprised of 12 treatments in total, which were the combina tions of three Vicia faba varieties (Giza-843, Nubaria-3, and Sakha-4) and four foliar application treatments (Control, Amc = 1.25 g/L Amcoton, KTS = 3.75 cm3 /L KTS, and Amc + KTS).
· Healthy seeds of faba bean were sown on 1 and 6 November for the 1st and 2nd seasons respectively. Faba bean varieties were sown at the equivalent of 95 kg ha-1 to achieve the recommended planting density (22- 25 plants/m).

Effect of Potassium Thiosulfate and Harpin Protein Combination on Second Season Cotton Productivity

Salih CANAVAR. Adnan Menderes Üniversitesi Ziraat Fakültesi Dergisi, 2022, 19(1), 55-59.

Since potassium is the primary osmotic agent for fiber growth and provides the necessary turgor pressure for fiber elongation, optimal cotton yield and fiber quality are highly dependent on adequate potassium uptake throughout the growing season. Potassium thiosulfate (KTS) can be applied through different irrigation systems and foliar sprays. Treating cotton with different combinations of KTS and harpin protein (a bioactivator) can have a positive impact on seed cotton yield and cotton early maturity, while the impact on yield composition and fiber quality (except fiber fineness) may be limited.
Materials and methods
· The different combinations of harpin protein and KTS with control were arranged in a Randomized Complete Block Design with three replications. The applications were control (non-treatment), harpin protein at peak squaring, harpin protein at first flowering, harpin protein at first flowering + after 21 days harpin protein, harpin protein at first flowering + after 21 days harpin protein + KTS, harpin protein at first flowering + after 21 days KTS.
· Application doses for harpin protein and KTS were 60 g/ha and 250 cc/100 L. The harpin protein and KTS were sprayed with a portable hand-held field plot sprayer using a water carrier volume of 400 L/ha.
