Enhancement quality and quantity of faba bean plants grown under sandy soil conditions by nicotinamide and/or humic acid application

Abstract

Background: Two field experiments were conducted at the Research and Production Station, National Research Centre, El-Nubaria Province, El-Behira Governorate, Egypt, during the two successive winter seasons of 2014/2015 and 2015/2016. This work aimed to study the enhancement effect of foliar application of nicotinamide at 5, 10, and 20 mg/L and/or humic acid at 5% on quality and quantity of faba bean plants (cultivar Sakha 4) grown under sandy soil conditions. Results: Data show that nicotinamide at 5, 10, and 20 mg/L and/or humic acid at 5% had a positive effect on growth parameters, photosynthetic pigments, seed yield, and yield components as well as some biochemical constituents of the yielded faba bean seeds (total carbohydrate, total phenolic content, proline, and free amino acids). Individually, nicotinamide treatments had a more positive effect than humic acid treatment and their effect was increased by increasing nicotinamide concentrations. The most promising treatment appeared due to the interaction between nicotinamide at 10 mg/L and humic acid. Hence, this treatment increased plant dry weight/plant by 32.67%, total photosynthetic pigments by 113.2%, seed yield/feddan by 110.16%, total carbohydrate by 9.4%, total phenolic content by 0.33%, proline by 24.83%, and free amino acids by 21.33%. Conclusions: We can conclude that nicotinamide and/or humic acid had a positive effect on growth parameters, photosynthetic pigments, seed yield, and yield components as well as some biochemical constituents of the yielded faba bean seeds. The most promising treatment appeared due to the interaction between nicotinamide at 10 mg/L and humic acid.

Effect of garlic extract, ascorbic acid and nicotinamide on growth, some biochemical aspects, yield and its components of three faba bean (Vicia faba L.) cultivars under sandy soil conditions

“…These results of nicotinamide are in agreement with those obtained by Sadak et al (2010), Erdal et al (2011, Sadak (2016) and Dawood et al (2019). The stimulatory effects of nicotinamide on plant growth were found to be correlated with the increase in content and activity levels of endogenous promoters as IAA (Table 4) (Wilkins, 1989).…”

“…These obtained results are in conformity with those obtained earlier (Osman et al,2010, Bakry et al 2011, Khattab et al, 2015and Abou-El-Seba et al 2016, and they showed that faba bean cultivars varied significantly on plant height, weight/plant (g), number of pods/plant, 100-seed weight (g), seed yield/plant and seed yield (kg/hectare) during the two growing seasons. Also, Bakhoum et al (2019), Dawood et al (2019) and El-Bassiouny et al (2020) confirmed this result on soybean, flax and wheat plants. These differences in morphological characters especially plant height among cultivars of faba bean might be due to genetically differences, difference in origin, growth habit and the environmental conditions of investigated cultivars.…”

“…Recently, Sadak (2016) reported that growth, yield components, indole acetic acid (IAA), photosynthetic pigments, total soluble sugars (TSS), free amino acids, proline and phenolic contents are significantly increased by soaking of Pisum sativum L. seeds with nicotinamide at the two dates of sowing. Moreover, Dawood et al (2019) concluded that nicotinamide and/ or humic acid had a positive effect on growth parameters, photosynthetic pigments, seed yield, and yield components as well as some biochemical constituents of the yielded faba bean seeds.…”

Effect of Humic Acid Application on Quantitative Parameters of Sugar Beet (Beta vulgaris L.) Cv. Shirin

“…The increase alkalinity increase for sugar beet could be related non-sugar compounds in sugar beet roots such as amino-nitrogen, Na and K (Feizi, et al 2017). The results are in harmony with those obtained by Dawood et al (2019). However, the higher application of humic acid (500 and 600 kg ha -1 ) was decreased the alkalinity significantly (P ≤ 0.05).…”

“…of sugar beet is a common species that is monogamous and diploid in terms of bud type (Akhtar et al, 2017). There are numerous reports about the sugar beet as a vital crop to man as a source of high energy and an important source of feed to livestock (Dawood et al, 2019). The importance of this crop comes from its growing in the newly reclaimed land and giving a high sugar recovery, as well as its lower water requirement.…”
