ENRICHMENT OF WHEAT BY ZINC FERTILIZER, MYCORRHIZA AND PREHARVEST DROUGHT STRESS

Hassan FARAHBAKHSH , Abbas KHASSE SIRJANI

Abstract

A field experiment was conducted to investigate the effects of Zn and mycorrhiza on enrichment possibility of wheat (Triticum aestivum L.) under preharvest drought stress condition. The treatments included irrigation (A1: normal irrigation, A2: preharvest drought stress) as the main plots and the combinations of zinc (Zn1: 0 kg ha-1 and Zn2: 2 kg ha-1 ) and mycorrhiza (Mc1: 0 kg ha-1 and Mc2: 200 kg ha-1 ) as the subplots. The results indicated that grain phosphorus, grain phytic acid, phytic acid to zinc ratio, grain yield and grain filling period decreased under drought stress condition. A significant reduction was observed in grain phosphorus, grain phytic acid, phytic acid (Phy) to zinc ratio and grain filling rate with application of Zn (2 kg ha-1 ). Grain zinc, protein, yield and final grain weight were higher at 200 kg ha-1 mycorrhiza than the control (0 kg ha-1 ). Finally, considering drought crisis in some developing countries, the treatment of preharvest drought stress with Zn (2 kg ha-1 ) saved 450 m3ha-1 of water, produced the second highest grain yield, the highest protein content and the lowest phytic acid and Phy/Zn ratio. Therefore, this treatment can be recommended as a suitable and practical approach to improve wheat grain yield and quality

Effects of Different Water Stress Levels on Biomass Yield and Agronomic Traits of Switchgrass (Panicum virgatum L.) Varieties under Semi-Arid Conditio

Erdal GONULAL, Suleyman SOYLU, Mehmet SAHIN

Abstract

A field experiment was conducted in the Wielkopolska region at the Gorzyń Research Station, Poland (52.34°N, 15.54°E) in Central Europe. The study was conducted over a 3-year period (2017, 2018, 2019) as a two-factorial design with four replications in the RCBD. The aim of the research was to determine the effect of the cultivar (‘Bolero’, ‘Tytan’) and the inoculation (Nitragina–seeds inoculation, Nitroflora I–seeds inoculation, Nitroflora II–soil inoculation, HiStick® Lupin–seeds inoculation) on plant development, seeds chemical composition and yielding of narrow-leaved lupin. The weather conditions and experimental factors significantly influenced on productivity of narrow-leaved lupin ‘Tytan’. Drought during the growing season reduced seeds and protein yields. After inoculation of HiStck the seeds yield was significantly greater by 12.4% (p < 0.01) and the protein yield after application of Nitroflora I or HiStick by 13.9% (p < 0.01) and 19.2% (p < 0.01), respectively. Correlation coefficients showed strong relations between number of pods and seeds per plant in both cultivars regardless of the inoculation variant, however the strongest relations in both cultivar were proved on HiStick treatment.
