“…Therefore, to further clarify whether these effects are positive or negative for intercropping, we synthesized and evaluated this result using a sustainability index [26]. The technique of assessing several factors of crop production practices was recognized as an innovative approach to systematically assess the cropping system's sustainability [38,39]. In this study, we created a sustainable evaluation index through 12 indicators, including crop yield, LER, yield increase, and net effect.…”

The bare row spacing between young jujube trees reduces resource use efficiency. Planting cotton between rows of jujubes can improve the efficiency of light, heat, water, and temperature resources. However, it is not clear how many rows of cotton between the jujube rows would be the most suitable pattern. A field study with different cropping systems was performed to investigate the land equivalent ratio (LER), the competition of cotton to jujube, and the sustainability index. The treatments included (1) monoculture jujube, (2) monoculture cotton, (3) jujube intercropped with two rows of cotton (J/C2), (4) jujube intercropped with four rows of cotton (J/C4), and (5) jujube intercropped with six rows of cotton (J/C6). The results showed that the LER under the J/C2, J/C4, and J/C6 systems were 1.17, 1.30, and 1.28, respectively. The LER and total yield were higher under J/C2 than under the J/C4 and J/C6 treatments. The overyielding rate of cotton was increased, while those of jujube were decreased with increasing rows of cotton. The competition between cotton to jujube was less than 0. The net, complementarity, selection effect, and sustainability index were significantly higher under J/C4 and J/C6 than under J/C2, with J/C4, showing stronger net effects. Both complementarity and selection effects contributed to the intercropping yield advantages. Comprehensively considering yield, economic efficiency, sustainability index, land use efficiency, and net effect, J/C4 is one of the most productive and sustainable planting patterns of jujube–cotton intercropping system in southern Xinjiang, which is the more ideal pattern in arid and semi-arid regions.

“…Perennial weeds present a distinct challenge due to their inherent ability to penetrate and thrive within mulch layers (Ruch et al, 2023). According to Gou et al (2022), when considering the measurement of organic systems on a per-area basis, they may exhibit superior performance compared to conventional systems. However, it is important to account for the yield gap in organic systems, as this factor may contribute to higher emissions per unit of output.…”

The agricultural sector is confronted with the formidable challenge of providing sustenance for a global population of 9 billion individuals by the year 2050, all the while mitigating adverse ecological and societal impacts. An attempt to address this difficulty has been made through the implementation of organic farming practices, which have yielded predominantly favorable results. Nevertheless, there are still certain obstacles that need to be addressed. Organic agricultural practices exhibit lower yields compared to conventional methods, while concerns persist regarding greenhouse gas emissions and fertilizer leaching. This paper provides an overview of existing organic and conventional agriculture systems and proposes that agroforestry, a deliberate integration of trees and shrubs with crops or livestock, may represent a promising avenue for advancing sustainable agriculture. Agroforestry possesses the capacity to sustain productivity and concurrently provide many ecosystem services through the use of nature-inspired methods. This study presents an overview of the prevalent methods and products associated with agroforestry, while also highlighting the positive environmental and social impacts it brings about. The present study aims to examine the obstacles encountered in the implementation of agroforestry practices and to suggest potential strategies for policy modification that could enhance the uptake of such practices among farmers. The findings of this review study indicate that agroforestry emerges as a very effective land use strategy for addressing both food security and environmental degradation concerns.

“…Enhancing vegetable productivity by using new innovative methods and technologies is the best alternative to sustain the nutritional security of the growing population, and income security for small and marginal www.extensionjournal.com farmers is the need of the hour. An intercropping system can allow sustainability in agriculture by competent resource management, crop diversification and improving soil fertility (Maitra et al 2021, Gou et al 2022 [16,11] . The multilayer farming (MLF) technique involving multispecies crop combinations is an innovative alternative agriculture practice for sustainable productivity that can provide greater economic return per unit area.…”

India has over 17% of world's population living on 2.4% the world's geographical area. In India, primarily farmers (about 85%) come under small and marginal farmers who practice contemporary agricultural methods with extensive use of fertilizers. The amount of arable land is lessening as a result of rapid population growth along with fast urbanization, land degradation due to soil erosion, and soil salinity. An innovative farming technique is the need of the hour not only to enhance crop productivity but also provide greater economic return per unit area. Multilayer farming is one such viable option to boost aggregate farm production and thus increase in farm income. Multilayer farming means growing and cultivating more than two crop at different heights on the same field at the same time. A study was undertaken in Ghaziabad district of Uttar Pradesh with the objective to demonstrate and create awareness among farming community about the benefits of multilayer farming and increase in farm profit. A pilot scale field experiment was conducted for consecutive two years in Ghaziabad district involving 8 farmers with one acre of land each growing various vegetable and fruit crops through multilayer farming technique. Various parameters like land equivalent ratio as an indicator of yield advantage of multi-crop farms over sole-crop farms, analysis of economics (benefit-cost ratio), impact of soil organic carbon and water on multilayer farming were investigated. The study effectively demonstrated effective utilization of vertical space and the participant farmers successfully cultivated three to four crops each season with LER value greater than unity. The study revealed increase in organic carbon percentage along with 30 percent less water consumption and benefit cost ratio of 2: 1 which was obtained on an average from one acre of land. Due to presence of more than two crops in the field helped farmers mitigate the risk of crop failure due to sudden change in weather conditions. Crops on bamboo structure had better quality produce which increased farm income. The paper highlights the benefits of cultivating multi-tier crop species for effective utilization of vertical space and different crop choices for higher monetary advantages.
