We conclude that irrigation of alfalfa in the Southeast is a marginal practice
A farmer must make a decision on whether or not it would be advisable to replant alfalfa based on the level of alfalfa residue still growing in the field.
Therefore, a late-season rest from grazing was not economically benefi cial to grazing alfalfa in this 3-yr experiment, and grazing alfalfa with summer stockers may be a viable option for producers in the southern Great Plains.
Considering all the factors, this study recommends that the optimal length of alfalfa phase in the alfalfa/crop rotation system should not more than 8 years.
Alfalfa can be grown alone or with a grass, but little information exists on the benefits of mixing alfalfa (Medicago sativa L.) with a grass in northern environments.
Thus, selection for improved nutritive value in total herbage of alfalfa may result in marked changes in plant morphology.
The potential seed yield of alfalfa varieties is sufficient to guarantee a profitable seed harvest.

What is green agricultural practices?5 answersGreen agricultural practices encompass environmentally friendly farming techniques aimed at sustainable and eco-conscious food production. These practices focus on soil health, crop productivity, and minimizing negative impacts on the environment. Examples include organic farming to protect soil health and provide disease-free crops, the Vetiver System to prevent soil erosion and enhance water retention, and the transition towards "green farming" characterized by natural agricultural technologies like mulching, reducing soil compaction, and minimizing the use of herbicides. Additionally, initiatives like the Common Agricultural Policy in Europe promote greening measures such as crop diversification and maintaining permanent grasslands to benefit the climate and environment. Overall, green agricultural practices prioritize sustainability, environmental conservation, and the well-being of both farmers and consumers.
What is marketing practices in agriculture?5 answersMarketing practices in agriculture encompass a wide array of strategies aimed at enhancing farmers' engagement in input and output markets, improving post-harvest management, increasing profitability, and ensuring sustainable development. These practices involve leveraging digital technologies like e-Agriculture, adopting efficient post-harvest practices such as sorting, grading, and value addition, optimizing marketing systems to benefit farmers economically, utilizing agromarketing tools to enhance competitiveness and quality of agricultural products, and promoting ecological producers through informed consumer engagement and strategic promotional mix. By integrating these diverse approaches, agriculture marketing practices aim to empower farmers, increase market access, improve product quality, and contribute to the overall growth and sustainability of the agricultural sector.
What is the important of farming years experience?4 answersFarming years of experience is important in agriculture as it contributes to farm productivity and safety practices. Studies have shown that farmer attributes, such as education and farming experience, are correlated with farm production. The years of schooling variable has a statistically significant and positive effect on farm production, with an increase in farm output ranging from 2.2% to 2.9% for each additional year of schooling. Additionally, younger farmers with less farming experience demonstrate a higher degree of risk tolerance and are more likely to engage in risk-taking behaviors, leading to potential injuries and lost working days. Therefore, farming years of experience not only impact farm productivity but also play a crucial role in ensuring the safety and well-being of farmers.
What are the best practices for farming a 2-hectare farm in agriculture?5 answersThe best practices for farming a 2-hectare farm in agriculture include engaging in arable crop production practices such as land preparations, planting, weeding, and fertilizer application. It is important to keep accurate records, especially for the cost of hired labor, in order to determine profitability. Access to labor, access to credit, and farm size are factors that determine the level of participation in arable crop production. Larger farms are more likely to adopt virtuous practices, but the effect of farm size is weak. Technical and cost issues linked to physical conditions can be impediments to the adoption of appropriate practices. Agroecological practices such as biofertilizers, natural pesticides, crop choice and rotations, intercropping, and agroforestry are not well integrated in actual agriculture. Sustainable agriculture requires a combination of advanced plant breeding, biotechnology, and improved systems-based integrated farm management practices. Traditional farming practices, such as agroforestry, intercropping, crop rotation, and organic composting, are gaining attention for their benefits in soil fertility, carbon sequestration, and sustainability.
Why do good agriculture practice?5 answersGood agricultural practices (GAP) are implemented to ensure food security, sustainability, traceability, and protection of natural resources and the environment. GAP can increase crop yield, reduce agrochemical use, improve soil organic matter, and increase farmers' income. Precision agriculture technologies, which align with GAP, can help comply with regulations and provide documentation of production conditions. Additionally, GAP reduces the incidence and intensity of pests and diseases and ensures proper fertilizer application. Sustainable agriculture, including the adoption of GAP, plays a significant role in protecting the environment and conserving resources. Good agriculture practices, such as monitoring cultivation, harvesting, and processing, are essential for ensuring the quality of medicinal plants used in health products and herbal medicines. Overall, GAP is crucial for promoting sustainable and environmentally friendly agricultural practices while meeting consumer demands and ensuring high-quality agricultural products.
Why alfalfa survives the winter or not?5 answersAlfalfa survives the winter or not depends on its fall dormancy and cold acclimation processes. Fall dormant alfalfa exhibits higher winter survival rates compared to non-dormant alfalfa. The accumulation of raffinose and amino acids increases in fall dormant alfalfa, which contributes to its cold tolerance. Additionally, the expression of genes related to raffinose biosynthesis is up-regulated in fall dormant alfalfa, while down-regulated in non-dormant alfalfa under cold acclimation. Furthermore, the expression of genes involved in proline metabolism is down-regulated in fall dormant alfalfa. These findings suggest that fall dormant alfalfa has enhanced cold resistance due to the accumulation of raffinose and amino acids, as well as the regulation of gene expression related to cold acclimation processes.
