Impact on plant productivity under low-fertility sandy soil in arid environment by revitalization of lentil roots

Abstract

Lentil is one of the essential legume crops, which provides protein for humans and animals. This legume can improve soil fertility through nitrogen fixation, which is imperative in low-fertility soils. The growth and productivity of lentil could be enhanced through improving nutrition and root revitalization. Therefore, the objective of this study was to assess the impact of root activator (RA) and phosphorus (P) application on morphological, physiological, agronomic, and quality traits of lentil under newly reclaimed low-fertility sandy soil in an arid environment. The RA was applied at four levels of 0 (RA0-untreated control), 1.25 (RA1), 2.5 (RA2), and 3.75 (RA3) l ha–1. RA contained 9% potassium humate, 1,600 ppm indole butyric acid, 200 ppm gibberellic acid, and 200 ppm naphthalene acetic acid. The recommended rate of phosphorus (P) fertilization in the newly reclaimed low-fertility sandy soil (75 kg P2O5 ha–1) was applied, and its amount was increased and decreased by 25 kg P2O5 ha–1 vs. non-added control. Thus, P rates were applied at four rates 0 (P0; control), 50 (P1), 75 (P2), and 100 (P3) kg phosphorus pentoxide (P2O5) ha–1. Our results revealed that treated lentil plants with the high levels of both treatments (RA3 and P3) exhibited superiority in root measurements (root length, total number of nodules plant−1, number of active nodules plant−1, dry weights of active nodules, and total root), nitrogenase activity, chlorophyll a and b, carotenoids, yield traits, and seed proteins and carbohydrates. However, the recommended P level (75 kg P2O5 ha–1, P2) under the high level of RA (3.75 l ha–1, RA3) displayed non-significant differences in yield traits (plant height, 1,000-seed weight, seed yield ha–1) and quality traits (protein and carbohydrate) with the high P level (100 kg P2O5 ha–1, P3). Accordingly, its recommended economically and environmentally to use this coapplication of RA3 and P3 in low-fertility soil for better lentil growth, and seed yield and quality.

Influence of Seed Soaking and Foliar Application Using Ozonated Water on Two Sweet Pepper Hybrids under Cold Stress

“…Likewise, the exogenous application using biostimulants is a sustainable approach to reinforcing the growth and production of different field crops under environmental stresses [22][23][24]. Several earlier reports deduced that the exogenous application of different biostimulants ameliorated physiological, biochemical, morphological, yield, and quality parameters of field crops [25][26][27].…”

Response of High-Yielding Peanut Cultivars to Various Seed Treatments Under Marginal Fertility Sandy Soil Conditions

“…Peanut, like other legumes, forms a symbiosis relationship with rhizobia (Bogino et al, 2006). The most associated role is to promote legume-Rhizobium symbiosis in photohormones, induce root growth stimulation, and provide more sites for rhizobia nodulation (Mahrous et al, 2015;El-Hady et al, 2022). Gypsum is one of the most primitive fertilizer forms utilized in peanut production.…”

Amelioration of the Detrimental Effects of Water Deficit Stress on Lentil (Lens culinaris Medik) Through the Utilization of Poultry Litter-Based Compost

“…), which belongs to the Fabaceae family, is a significant pulse crop cultivated in Bangladesh due to its crucial role in food, feed, and cropping systems (Iqbal et al, 2006). Legumes, when included in cropping systems, improve soil fertility and crop yield through nitrogen fixation (Abd El-hady et al, 2022), biological nitrogen fixation (BNF)symbiotic association with microorganisms like rhizobia (Kebede, 2021). Benefits of legumes include increased nutrient availability and uptake for subsequent crops (Sinclair and Vadez, 2012;Hauggaard-Nielsen et al, 2008), improvement of soil properties (Jena et al, 2022), breaking pests' cycles (Stagnari et al, 2017), and enhancement of soil microbial activity (Yang et al, 2020).…”
