“…Due to these requirements, faba bean crop cycle starts in autumn in mild climate areas and in spring in cooler ones, but the optimal planting time for maximizing earliness, yield and quality is strictly matched to the growing environment (Myers et al, 1982;Gomez et al, 2017). In this regard, in Pakistan, Khalil et al (2010) reported that the highest yield is favored by early October sowing, compared to late summer or midautumn planting, and Fasheun and Balogun (1992) detected the significant correlation between dry matter production and radiation use efficiency as affected by planting time.…”

A research was carried out in southern Italy in order to evaluate the effects of two farming systems (open field, greenhouse) and five transplanting times (27 September, 11 October, 25 October, 8 November, 22 November) on plant growth, harvest precocity, fresh pod yield and seed quality of organic faba bean. Crop biomass and root expansion were higher in open field than in greenhouse. The fourth planting time resulted in the highest crop biomass, whereas the second crop cycle showed the highest leaf area index. Greenhouse crops showed higher precocity than the open field ones by about two weeks, as well as the first transplant; the delay in harvest beginning increased from the second to the fourth planting time. Both fresh pod and seeds yield were significantly higher in open field than under protected environment with the third and fourth planting times. Seed fiber and protein content showed higher values in greenhouse compared to open field and increased with the transplant delay. Seed polyphenols attained higher concentration in open field and with the two earliest planting times. Overall, 25 October to 8 November planting times in open field best fitted the southern Italy growing conditions in terms of pod yield, but the 27 September to 11 October planting times resulted in the highest harvest precocity, remarkably enhanced under greenhouse growing, whereas seed quality was controversial.

The NDVI was used to discriminate tobacco variety, assess fertilizer levels, and determine the impact of planting date on separating crops. A split plot design with four planting dates, September, October, November, and December, as main plots, variety as subplot, and fertilizer treatments as sub-subplots was used. Radiometric measurements were taken from 5 m × 5 m sampling plots, using a multispectral radiometer. The September, October, and November crops had significant variety x fertilizer treatment differences ( < 0.05) from the age of 10 weeks. T 66 and KRK26 varieties had similar ( > 0.05) NDVI values and these were greater ( < 0.5) than those for K E1. The 100% and the 150% fertilizer treatments were similar ( > 0.05) and both were greater ( < 0.05) than the 50% fertilizer treatments. All of the fertilizer and variety treatments at the December planting dates had similar reflectance characteristics ( > 0.05), which were lower ( < 0.05) than the September and October planting dates. The results showed that planting dates, varieties, and fertilizer levels could be distinguished using spectral data. Weeks 10-11 and 15 after the start of the experiment were optimal for separating the planting date effect.
