“…Pearl millet ( Pennisetum glaucum L.) is an ideal model for the tolerance of several biotic and abiotic stresses and is considered a moderately salt-tolerant plant [ 1 ]. Furthermore, pearl millet has significant potential as a sustainable forage crop, especially in parched and semiparched areas that are threatened by environmental changes [ 2 ].…”

“…Although millet plants are resistant to high soil salinity (up to 15 dS m −1 ), the quality of the forage crop is severely reduced due to the harmful effect of salinity on the chemical composition of the plant [ 1 , 8 ]. Therefore, to address this issue, we attempted to develop soil amendments using decomposed shrimp wastes at high temperatures to produce biochar.…”

Shrimp waste is rich in organic compounds and essential plant nutrients, e.g., calcium (Ca), and converting these wastes to organic fertilizer is important for environmental preservation and to achieve sustainable agricultural management. In the current study, Ca-rich biochar was prepared from shrimp wastes (SWB) by pyrolysis at 300 °C. We hypothesized that the Ca-rich biochar will help in solving the problem of plant growth in saline soil by reducing sodium (Na) uptake and mitigating oxidative stress. The current study aimed to investigate the effect of SWB on the quality of saline sandy soil and the mechanism of salt resistance in pearl millet (Pennisetum glaucum L.). Pearl millet plants were planted in saline sandy soil (10 dS m−1) in wooden boxes (1.3 × 0.8 m size and 0.4 m height), and 5 doses (0, 1.0, 1.5, 2.0, and 2.5% (w/w)) of SWB were added. SWB application increased the soil quality and nutrient uptake by pearl millet plants. The highest rate of SWB increased the soil microbial biomass carbon and the activity of dehydrogenase enzyme by 43 and 47% compared to the control soil. SWB application reduced the uptake of sodium (Na+) and chloride (Cl−) and increased the K/Na ratio in the leaf tissues. SWB addition significantly increased the activity of antioxidant enzymes, e.g., ascorbate peroxidase (APX), polyphenol oxidase (PPO), and pyrogallol peroxidases (PPX). The application of 2.5% SWB to the saline soil increased the soluble carbohydrates and proline in plant leaves by 75 and 60%, respectively, and reduced the malondialdehyde (MDA) by 32% compared to the control. SWB enhanced the antioxidant defense and mitigated oxidative stress by improving the synthesis of osmoprotectants, e.g., soluble carbohydrates and proline. Sandy saline soils in arid and semiarid areas suffer greatly from low organic matter contents, which reduces the soil quality and increases the risk of salt during plant growth. The high organic matter and calcium content (30%) in the shrimp waste-derived biochar improved the quality of the saline sandy soil, reduced the uptake of toxic salts, and increased the quality of the forage material. The addition of recycled shrimp waste to saline low-fertility soils improves soil productivity and is safe for soil health.

“…Pearl millet is a strong, harsh climateadapted grain crop, ideal as a model to test abiotic and biotic stresses. It has a high crop development rate, enormous leaf area index, and high radiation use effectiveness that supports its high potential yield (Shivhare & Lata, 2017;Ullah et al, 2017;Kadivala et al, 2019). It can thus support the fight against poverty and lack of nourishment due to its resilience to climate calamities (Jukanti et al, 2016;Rijsberman, 2014;Ndiku et al, 2014).…”

“…Micronutrient deficiencies are becoming increasingly common in agriculture due to increased removal due to high yielding; high uptake crops (Kadivala et al, 2019). Application of boron (B) alleviates the toxicity of aluminum by regulating the activities of antioxidant enzymes, proline, secondary metabolite contents, stabilizing integrity of the proteins, and reducing reactive oxygen species and Al concentrations (Riaz et al, 2018).…”

D ROUGHT and salinity are the most limiting factors for crop production in arid and semiarid areas. Moreover, pearl millet cultivation may be an excellent selection in arid and saline lands. Therefore, two field experiments were conducted at the Desert Research Center, Agriculture Experimental Station at Ras Sudr, South Sinai Governorate, Egypt during 2018 and 2019 seasons, to study the effect of seed priming (as seed soaking) using five salicylic acids levels (tap water as a control, 50, 100, 150 and 200 mg/L SA) and fertilizing soil application by five boron rates (without boron, 1.0, 2.0, 3.0 and 4.0 kg boron/fed, as boric acid) on pearl millet yields. The results showed that plant height (cm), panicle length (cm), panicles number/ m 2 , grain weight/panicle (g), seed index (g) and grain protein content percentage as well as biological, grain and protein yields (kg/fed) were significantly increased by salicylic acid (SA) levels in both seasons. Soaking the grains of pearl millet in 200 mg/L SA treatment was the best practice in both seasons as compared to the other treatments. Regarding the effect of boron (B) treatments, all the abovementioned characters were significantly affected by B treatments in the two studied seasons. Adding 3 kg B/fed gave the highest values of all the studied attributes in both seasons. It is clear that from the obtained results pearl millet grain primed in 200 mg/L SA along with B at a rate of 3 kg/fed could be recommended for enhancing pearl millet yields under saline soil conditions.

Pearl millet [Pennisetum glaucum (L.) R. Br.] constitutes the third most important cultivated cereal and source of nutrients in Burkina Faso. The study carried out in 2018 and 2019 at the Saria Environment and Agricultural Researches Station aimed to assess the effects of tillage and organo-mineral fertilization on the quantities of minerals accumulated in pearl millet stover that could be used in animal diets as nutritional supplements. The experimental design was a completely randomized block with a split-plot arrangement of treatments, three replications with four tillage methods assigned to main plots and eight organo-mineral fertilizations to subplots. Results showed that the quantities of minerals accumulated in pearl millet stover were affected by tillage methods and organo-mineral fertilizations as well as by their interactive effects. Compost associated with mineral fertilizers resulted in higher accumulations of minerals in pearl millet stover. In terms of tillage methods, the results indicated that ploughing and scarifying were more favorable for greater but not varying mineral accumulations compared to manual zaï and tie-ridging.
