Abstract

The deficiency of micronutrients is one of the main reason for low seed yield in oilseed crops in many developing countries including Pakistan. Therefore, this two-year field study was conducted to assess the influence of foliage applied micronutrients (individual/or in combination) on the yield and quality of sunflower hybrids. For this study, we hypothesized that foliage application of micronutrients will improve achene yield, oil quality and net returns in sunflower hybrids. The results indicated that sunflower hybrid ‘Parsun’ produced the higher head diameter, and had more 1000-achene weight, achene yield, oil content, stearic acid, palmitic acid and linolenic acid as compared to ‘FMC-1’. Likewise the tallest plants, greater number of leaves, maximum seed weight, the highest achene yield, and oil content were noted with the combined application of Zn+B. Highest achene yield with combined application of Zn+B also resulted in highest net income. The application of micronutrient also improved the oil content and oil quality. In conclusion, the hybrid ‘Parsun’ should be grown with the application of Zn+B (10 and 2 kg ha -1 respectively) to achieve higher achene yield, better seed quality and to earn higher net benefits in sunflower hybrids under arid climate of Layyah Punjab, Pakistan.

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.
