“…The "*" represents a significant difference between monocropping with the conventional N treatments and intercropping with zero and reduced N treatments (p < 0.05). Intercropping is a simple and effective way to modify the microclimate of rice canopies [30][31][32]. In our two-season field experiments, intercropping treatments increased the canopy air temperature compared with the rice monocropping treatments (Figure S2).…”

“…Additionally, rice/water mimosa intercropping reduced the dew point temperature and relative humidity of rice canopy (Figure S2). Similarly, many studies have demonstrated that intercropping reduces the canopy relative humidity and dew point temperature [30,31]. In the rice/water mimosa intercropping system, water mimosa prostrated growth, rice erected growth, and the height of rice was much higher than that of water mimosa [21].…”

Cereal/legume intercropping is an effective agricultural practice for pest and disease control and crop production. However, global research on rice and aquatic legume intercropping is relatively rare. A field experiment during two seasons (2018 late season and 2019 early season) was conducted to explore the effects of rice and water mimosa intercropping on rice canopy microclimate, pest and disease, yield, grain quality, and economic income. Two cultivation patterns including rice/water mimosa intercropping and rice monocropping were employed, and three nitrogen (N) fertilizer application levels, including zero N (ZN, 0 kg ha−1 N), reduced N (RN, 140 kg ha−1 N), and conventional N (CN, 180 kg ha−1 N) levels, were applied for the above two cultivation patterns. The results showed that rice/water mimosa intercropping formed a canopy microclimate of rice with higher temperature and lower relative humidity and dew point temperature. In addition, there was a significant reduction in the occurrences of rice leaf blast by 15.05%~35.49%, leaf folders by 25.32%~43.40%, and sheath blight by 16.35%~41.91% in the intercropping treatments. Moreover, rice/water mimosa intercropping increased rice per unit yield by 43.00%~53.10% in the late season of 2018 and 21.40%~26.18% in the early season of 2019. Furthermore, rice grain quality was totally improved, among which brown and head rice rates increased but rice chalky rate and chalkiness degree decreased in the intercropping system. We suggest that combining rice/water mimosa intercropping and N fertilizer reduction can be used as an environmentally friendly eco-farming technique because it can decrease N fertilizer application by approximately 40 kg·ha−1. This combination would not only mitigate nonpoint source pollution but also obtain advantages for controlling rice pests and diseases that would alleviate pesticide usage and improve rice yield and grain quality, which can be extended for green rice production to increase income for producers.

“…The suppressed weed population and growth in the two intercropping treatments means that the plants do not experience competition in utilizing growth factors compared to conditions where the plants are shaded by weeds and have limited growing space. Kresnatita et al (2018), stated that in optimal growth room conditions, photosynthesis runs optimally so that it has an impact on the size, number of cells, and the development of intercellular cells. As a result, the number and size of plant stems, leaves and roots increase, which is ultimately reflected in the dry biomass weight (Herlina & Prasetyorini, 2020).…”

The aim of the research is to examine the effect of intercropping corn with leguminous crops on weeds and land use efficiency. The experimental research method was designed using a randomized complete block design (RCBD) with three blocks. The treatments tested were monocrop planting patterns and intercropping between corn and leguminous crops. The results of the research showed that 16 weed species were found with high species diversity, evenness, dominance, and abundance, so that there were six dominant species that existed during plant growth. Peanuts and cowpeas are suitable for intercropping with corn because they can suppress the population and growth of weeds. Soybeans, green beans, and red beans are not suitable because they are not effective in suppressing the population and growth of weeds and compete with corn, so that corn yield losses due to competition are 38.20%–40.96% and due to weed competition, they reach 62.37%–63.77%. The best ecological and agronomic land use efficiency was obtained by intercropping corn with peanuts and cowpeas, with NKL values based on dry biomass weights of 1.90 and 1.89 (NKL > 1) and dry seed weights of 1.79 and 1.78 (NKL > 1).

“…Tumpangsari merupakan sebuah sistem produksi tanaman dengan pencapaian hasil yang tinggi dan stabil, serta menghasilkan penggunaan sumber daya yang efektif (Yildirim & Ekİncİ, 2017). Tanaman sela pada tumpangsari berperan sebagai barrier atau buffer kondisi lingkungan yang tidak terbentuk pada monokultur, misalnya penurunan intensitas cahaya matahari (Kresnatita et al, 2018), penurunan suhu (Kresnatita et al, 2018;Nyawade et al, 2019), penekanan evaporasi (Kubota et al, 2015) dan peningkatan kadar lengas tanah (Ndiso et al, 2017) serta peningkatan kelembaban (Kresnatita et al, 2018). Tumpangsari juga mendorong terjadinya peningkatan keanekaragaman dan kelimpahan biotik, sehingga mengurangi dampak negatif dari penyakit dan hama serta mengefektifkan penggunaan sumber daya (Yildirim & Ekİncİ, 2017).…”

Soybean is an important food crop for Indonesia after rice and corn. Soybean productivity in Indonesia is still low because most farmers use monoculture cropping patterns which has many weaknesses. Intercropping is an alternative to increase soybean productivity because it has many advantages. Soybeans can be intercropped with corn because the two plants have different physical characteristics, physiology and growth patterns. This research aimed to obtain information about the diversity and abundance of weeds in soybean and corn intercropping. The study was conducted using a single factor treatment design which will be arranged in a single plot field design, using Grobogan variety soybean and Bisma variety corn. The treatment was the proportion of soybean and corn populations which consisted of 4 proportions, i.e. 2:1, 3:1, 4:1, and 5:1, and monoculture soybeans were also planted as a control. Observations on weeds were carried out at the age of 2, 8, and 12 weeks after planting (before harvest) with vegetation analysis. The size of each sample is 0.5 m x 0.5 m with 15 sample plots/plots. The results showed that based on the summed dominance ratio (SDR) in the research area, 16 species of weeds were dominated by broadleaf weeds, with the dominant types of weeds being Phyllanthus urinaria L., Eleusine indica L., and Oryza sativa L. The results showed that based on the Summed Dominance Ratio (SDR) in soybean there were 16 species of weeds that were dominated by broadleaf weeds, with the dominant types of weeds being Phyllanthus urinaria L., Eleusine indica L., and Oryza. sativa L. Weeds growing on soybean intercropping with corn and soybean monoculture have a medium diversity index (H').
