Impact of Micronutrients Foliar Appliction and Potassium Fertilizer Levels on Productivity and Quality of Sesame Under Sandy Soil Conditions

Abstract

The desired goal of this investigation was to study the effect of eight micronutrients foliar application [Zn, Fe, Mn, Zn + Fe, Zn + Mn, Fe + Mn, Zn + Fe + Mn and control (tap water)] and three potassium fertilizer levels (check, 24 and 48 kg K 2 O/fad.) on yield, their attributes and seed quality of sesame grown in sandy soil. The obtained results revealed that, foliar application of Zn + Fe + Mn led to a significant increase in most yield attributes, seed and oil yields/fad., as well as seed oil % during both seasons. Plant height, fruiting zone length, No. capsules per plant, No. and weight of seeds per capsule, weight of seeds per plant and 1000-seed weight, seed and oil yields/fad., as well as, seed oil % exhibited significant increase due to raising K level up to 48 kg K 2 O/fad. It could be concluded that foliar application of Zn + Mn or Zn + Fe + Mn along with 48 kg K 2 O/fad., produced the highest sesame seed and oil yields/fad.

Mitigation of the impact of water deficiency on intercropped sesame and peanut systems through foliar application of potassium-silicate and triacontanol

“…Application of K-Si and TRIA not only increased seed yield but also enhanced the percentage of seed oil content by 11.9 and 9.9 % in the first season and by 7.5 and 6.7% in the second growing season, respectively. These results are in agreement with Yasin and Abdelsalam (2022), who found that plant height, the number of capsules per plant, weight of seeds per capsule, the weight of seeds per plant, 1000-seed weight, and seed yield per hectare, as well as percentage of seed oil were increased due to application of higher potassium fertilizer level, compared to no application.…”

“…Gomaa et al (2021) indicated that spraying with K-silicate increased the water use efficiency of peanut, as compared to no spraying treatment. Foliar application of potassium silicate not only increased seed yield, yield components, and oil content under fully irrigated but also alleviated the harmful effects of drought stress on sesame plants (Yasin and Abdelsalam, 2022). Whereas, Abd-Allah et al, (2021) reported that spraying with 200 ppm K-silicate to faba bean intercropped with sugar beet increased the water equivalent ratio to 1.37, compared to 1.25 under no spraying.…”

Soil fertility status: As affected by micronutrient application in groundnut

“…Higher value of Zn status after crop harvest was recorded under the treatment receiving soil application of T 7 (FeSO 4 @ 15 kg ha -1 + ZnSO 4 @ 8 kg ha -1 ) in all season as well as in pooled data and remained at par with treatment T 3 and T 9 . These findings were supported by Aboyeji et al (2020) [4] , Ali and Mowafy (2003) [5] , Arunachalam et al (2013) [6] , Elayaraja (2014) [7] , Habbasha (2014) [8] , Majumdar (2001) [9] , Manasa (2013) [10] , Meena et al (2015) [11] , Polara et al (2009) [12] , Rekhi et al (2000) [13] Saha et al (2015) [14] , Veeramani et al (2015) [15] .…”

Effect of Seed Fungicide Treatment, Microelement Fertilizer and Mepiquat Chloride Applications on Yield and Yield Components of Peanut

“…Foliar application of Zn element could repair zinc shortage. Highest seed yield, oil and protein content were reported with the foliar application of (Darwish et al, 2002;Ali and Mowafy, 2003;El Habbasha et al, 2013;Irmak et al, 2016;Christopher et al, 2019). Molybdenum is essential for nitrogen fixation and it was recommended for some legume crops but controversial findings on peanut yield were reported.…”
