“…Crop rotation with legumes is reported to help improve soil structure [17] and retain more moisture in the soil at greater depths [18]. As a result, it appears that the above technique adds to production optimization once again and coincides with past research.…”

Sorghum is a Poaceae family plant that produces a lot of hay. A field experiment was carried out at the University of Thessaly’s experimental farm to investigate the hay yield and quality characteristics of six different sorghum varieties (V1: Buffalo grain, V2: Elite, V3: Big Kahuna, V4: 25K1009, V5: 4264, and V6: 5D61) under different nitrogen fertilization levels (N1: 0, N2: 80, N3: 160, and N4: 240 kg ha−1, using urinary ammonia 40-0-0). Pea for silage production was established in the same field prior to sorghum cultivation. Hay yield was found to differ significantly between the tested varieties and was also influenced by nitrogen fertilizer. Nitrogen fertilization has a statistically significant effect on sorghum production, with a higher nitrogen supply contributing to a higher protein content in the sorghum yield. Other hay quality indicators, such as ash, NDF, and ADF, demonstrated differences between the different varieties and nitrogen fertilizer levels. According to the study, the variety that had stable output was “Elite”, which had good quality attributes and could be used as an alternative to feed production before sorghum development.

“…In the context of irrigated agriculture, the application of low-energy precision irrigation methods is very appealing (Rajagopal et al, 2014;Bordovsky, 2019). Further, green manuring (perhaps with locally available plants) could lead to greater moisture content within the rooting zone and greater crop yields (Karyoti et al, 2021). Applying the resource-recycling concept, could mean more intense use of wastewater recycling for irrigation but also considering potential contamination and salinization effects (Zhang & Shen, 2019).…”

Agriculture evolved to increase crop productivity and diminish plague effects. As a negative outcome of the human footprint by agriculture and industrialization, overall economic practices have led to substantial alterations in the environment (i.e., greenhouse gas production, elevated atmospheric temperature, more extreme climatic events), collectively known as climate change. The fast-changing environment due to climate change is most common in the tropics, the impacts of this phenomenon are perceived in different regions of the world, where most agricultural activity occurs. These facts reinforce the requirement for diminishing climate change producing activities and implementation of adaptive practices for long-term agricultural productivity and sustainability. Albeit may sound counter-intuitive, agroecological systems and traditional knowledge may provide alternatives to mitigate climate change effects in the context of agriculture. This review comprehensively describes the development of irrigated agriculture, major effects of climate change on irrigation, and further explores alternative practices stemming from agroecological systems or traditional knowledge, which could improve agricultural productivity and sustainability. Among some strategies, it is proposed to establish climate risk planning, agricultural producers must modify the application of their inputs to adjust to the new water and thermal requirements; implement conservation techniques to reduce the loss of soil moisture and thus ensure the development of crops in a drier and warmer environment as indicated by climate change projections. Likewise, the implementation of varieties tolerant to water stress is one more adaptation action that would allow continuing cultivating in lower regions, where the largest irrigated area is concentrated and which would receive the greatest impact from an increase in temperature. In this way, it will be necessary to implement new approaches, technologies and policies to learn from the past, following the new climate scenarios, conserving and making rational use of natural resources.

“…In general, the technique of green manure can imply leaving plant residue on the soil surface, to act as natural fertilizers. Additionally, this technique reduces pollution by minimizing the need for other agrotechnical measures: fungicides and nematicides [95], fertilizers [96], etc. Inadequate use of this technique (not choosing the sowing time adequately, not choosing the green manure species wisely) can disrupt the development of the main crop.…”

Non-Chemical Weed Control for Plant Health and Environment: Ecological Integrated Weed Management (EIWM)

et al. 2022

View full text Add to dashboard Cite

Herbicide application has long been considered the most efficient weed control method in agricultural production worldwide. However, long-term use of agrochemicals has numerous negative effects on crops and the environment. Bearing in mind these negative impacts, the EU strategy for withdrawing many herbicides from use, and modern market demands for the production of healthy and safe food, there is a need for developing new effective, sustainable, and ecological weed control measures. To bring a fresh perspective on this topic, this paper aims to describe the most important non-chemical weed control strategies, including ecological integrated weed management (EIWM), limiting weed seed bank, site-specific weed management, mechanical weeding, mulching, crop competitiveness, intercropping, subsidiary crops, green manure, and bioherbicides.
