Diversified Crop Rotation: An Approach for Sustainable Agriculture Production

Abstract

Diversified crop rotation (DCR) improves the efficiency of farming systems all over the world. It has the potentiality to improve soil condition and boost system productivity. Improved soil attributes such as increased soil water uptake and storage, and a greater number of beneficial soil organisms, may improve yield tolerance to drought and other hard growing conditions in a variety of crop rotations. Crop rotations with a variety of crops benefit the farmers,reduce production risk and uncertainty, and enhance soil and ecological sustainability. Farmers may be able to diversify their sources of income by adopting diversified crop rotations. Furthermore, because of the distinct structure, function, and relationship of plant community with soil in DCR, it contributes to the long-term development of soil health by decreasing insect, weed, and disease incidence and increasing the physical and chemical structure of the soil. DCR is becoming more popular approach for maintaining sustainable crop production. This review provides the evidence of the significance of DCR, challenges to adapt it, and possible way out to overcome the challenges.

Financial Profitability of Diversified Farming Systems: A Global Meta-Analysis

“…Third, based on our data, combined practices, crop rotation, embedding natural habitat, and agroforestry, each lead to significantly higher profits in terms of net income, or benefit-cost ratio in the case of agroforestry. Previous reviews have similarly suggested that crop rotation usually results in higher income and fewer production risks, particularly for low-income smallholder farmers (Feliciano, 2019;Shah et al, 2021). However, the adoption of diversified rotation systems may be negatively influenced by the higher investment (e.g., inputs, machinery, labour) needed to integrate and manage extra crops compared to simpler rotations (Feliciano, 2019), which may explain the higher costs for crop rotations found in our study.…”

Impact of Rotational Sequence Selection on Weed Seedbank Composition in Australian Broadacre Crops

“…The C-W-B-P-C rotational sequence also provided distinct advantages with respect to the management of common annual weeds in dryland rotations. For example, planting canola in year 1 of a rotation would enable the targeted control of gramineous weeds, including herbicide-resistant annual ryegrass, using multiple selective preemergent herbicides [33]. In low input, no tillage, or conservation tillage systems, a subsequent competitive wheat or barley crop following canola can typically provide fierce weed competition due to early vigour traits expressed by these cereals [33].…”

Pulse and other legumes that follow cereal crops benefit from a depleted weed seedbank and can generally fix substantial atmospheric nitrogen, further benefiting the subsequent canola crop and its related yields [34].…”

“…It helps in understanding the importance of the disease-free crop and to get the maximum output. In similar objectives, the crop rotation policy also helps [14]. e benefit of crop rotation is that the soil is not getting exhausted with similar types of nutrients in the soil, and it helps to maintain a good balance of the different nutrients in the soil.…”
