“…Additional evidence for the potential benefits of delaying the planting date has on millet yield in Senegal can be seen in other studies, thus confirming our results (Araya et al, 2022;Vieira Junior et al, 2023). Finally, other studies in Senegal on the use of N fertilizer for millet found the range of the best fertilizer rates to go from 68 kg N ha −1 to 120 kg ha −1 (Araya et al, 2022;Bastos et al, 2022;Isah et al, 2020;Vieira Junior et al, 2023), which is in agreement with our results. for the alternative agricultural scenarios after running the FARMSIM simulations.…”

In Senegal, agriculture is an important sector underpinning the socioeconomic fabric of the populace. Notably, the agricultural production in this region exhibits heightened sensitivity to climatic perturbations, particularly droughts and heat waves. This study aims to determine the resilience of different agronomic interventions for farmers practicing mixed farming that produce both crops (i.e., groundnut (Arachis hypogaea L.) and pearl millet (Pennisetum glaucum (L.) R. Br.)) and raise animals in the Groundnut Basin in Senegal, which holds historical and socioeconomic significance. To understand the current situation regarding demographics, economics, consumption behavior, and farm operations for smallholder farmers, data were comprehensively collected from government and nongovernment organizations (NGO) reports, scientific papers, organization databases, and surveys. Additionally, the Agricultural Production Systems sIMulator (APSIM) was used to understand how combinations of three planting dates, three plant densities, and six urea nitrogen (N) fertilizer rates affected the yield of pearl millet, which were used as the alternative scenarios to the baseline in the farm modeling and analyses. All the collected and generated data were used as inputs into the Farm Simulation Model (FARMSIM) to generate economic, nutritional, and risk data associated with mixed farming systems. The generated data were then used to determine the resilience of the alternative scenarios against the baseline. Initially, a multi‐objective optimization was employed to meet nutritional needs while maintaining a healthy diet at the lowest cost. Then, the scenarios that met the population's nutritional requirements were evaluated based on four economic indicators: net cash farm income (NCFI), ending cash reserves (EC), net present value (NPV), and internal rate of return (IRR). Lastly, those that passed the economic feasibility test were ranked based on risk criteria certainty equivalent (CE) and risk premium (RP). The analyses found N fertilizer rates of 0, 20, and 100 kg N ha−1 were generally economically not feasible. Additionally, medium (early‐July to late‐August) and late (late‐July to mid‐September) planting dates generally performed better than early (early‐June to late‐July) planting dates, while plant densities of 3.3 and 6.6 pL m−2 performed better than 1.1. The robust resilience approach introduced in this study is easily transferable to other regions.

The field experiment was conducted during Zaid season 2022 at the experimental field of Crop Research Farm, Department of Agronomy, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj and Uttar Pradesh, India. The soil of the experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.3), low in organic carbon (0.48%), available nitrogen (230 kg/ha), available phosphorus (13.60 kg/ha) and available potassium (215.4 kg/ha). The treatments consist of 3 levels of Nitrogen (40 Kg, 50 Kg and 60 Kg/ ha) as a basal application and Iron (0.2, 0.4 and 0.6 %) as foliar spray along with control. The experiment was layout in Randomized Block Design with Ten treatments each replicated thrice. Growth attributes namely higher plant height (101.57cm), maximum dry weight/plant (14.83 g), more number of tillers/hill (8.87) and yield attributes namely higher panicle length (18.61 cm), grains/panicle (1389.30), grain yield (1.79 t/ha) and straw yield (2.53 t/ha) were observed with application of nitrogen 60 Kg/ha and iron 0.6%.

“…In addition, analyses of the chemical composition of these litters showed significantly higher concentrations of P and K in coir-husk fiber, essential components along with N in agricultural fertilization, in particular in food and biofuel crop production. On the other hand, tropical soils tend to be poor in N, P and K (Isah et al, 2020 ). Thus indicating that after use as poultry litter, this material can be composted and used as a natural fertilizer in agriculture (Frazão et al, 2021 ), once again promoting sustainability and making production cheaper, since Brazil has large agricultural areas, being one of world’s leading producers and suppliers of food, fibers and bioenergy (Fao, 2017 ) and is highly dependent on imported fertilizers, mainly from Russia, which makes this research highly important for the Brazilian agricultural sector.…”

Ammonia (NH ) from manure is a concern in raising broiler due to possible damages to production and the environment. Brazil is the main exporter of chicken meat in the world and is also responsible for large waste of poultry litter. The country, likewise, figures as top 5 producers of green coconut, which results in considerable volumes of waste, since 80%-85% of the fruit is unusable. This work analyzes the ammonia concentration profile of two bedding substrates for raising broiler, to know, coir-husk fiber and a commonly used pine wood shavings in a Brazilian climate. A differential home-made photoacoustic cell combined with a diode laser was employed for sensing ammonia at trace levels. Such combination confers selectivity as well as lower limits of detection to the system. The chemical compositions pH, N, C, Ca, Mg, P O and K O were also determined, in addition to the moisture, dry matter and mineral content of substrates and litters. NH concentrations varied from (0.9 ± 0.3) ppmv to (19 ± 3) ppmv and from (2.1 ± 0.5) ppmv to (21 ± 3) ppmv for the coir-husk fiber and wood shavings substrates, respectively. Results showed the feasibility of using coconut fiber as poultry litter in regions where this material is a common waste. Moreover, as NH concentrations were lower for coconut fiber bedding compared to shavings, this coir-husk fiber is a potential residue to guarantee the environmental sustainability by Brazilian poultry farming. Coir-husk fibers presented significantly higher amounts of P and K in comparison to pine wood. NH profiles revealed that coir-husk fiber emitted lower quantities than wood shavings. Besides, a delay on the NH emission pattern was clearly seen when the coconut waste was the bedding material. Such a tendency was confirmed by the logistic model. Our findings, in turn, make the coir-husk an environmentally friendly alternative low-cost product for poultry litter as well as its potential use as natural fertilizer. The later deserves attention since there is a need to accurately assess the emissions of methane, nitrous oxide, and carbon dioxide during the composting process. In Brazil, the waste generated by the high production of green coconut is an environmental liability. The cost of poultry production has been high, reducing the profit of producers, who seek to make production cheaper. Measuring NH from poultry activity in Brazil, a tropical country, aims to control management and reduce production losses, since NH is a harmful gas to birds. The measurement of NH concentrations at trace levels from raising broilers by photoacoustic diode laser spectroscopy, to the best of our knowledge, has been reported for the very first time.
