“…However, the results observed here agree with Hernandes et al (2010) and Lopes et al (2013), which, however, verified that as the N doses increased, consequently the productivities increased, being the highest yields obtained when applied approximately 150 kg ha -1 of N. In fact, Korndörfer et al (1999) and Ning et al (2017) consider that the effect of Si is more expressive on the control of diseases, pests and resistance to water stress and not always these beneficial effects are linked to grain yield.…”

“…In other words, the effect of N doses on vegetative growth, characterized by increased height, dry shoot mass and number of tillers, promoted a greater redistribution of photo assimilates to the panicles and consequently to the grains, resulting in an increase in the TSW, that is, evidencing that the increase of doses of N may promote increase in TSW (Wu et al, 2017;Ning et al, 2017).…”

“…Silicon (Si) is the second most abundant element in the soil (preceded only by oxygen) and is considered a mineral element beneficial to the growth and development of many grass species, such as wheat, barley and rice (Ning et al, 2017). In rice, absorbed silicon is accumulated in the tissues and contributes to increase the photosynthetic rate and the efficiency of water use and reduce the transpiration rate and toxicity to heavy metals (Seebold et al, 2004;Marxen et al, 2016).…”

There is much doubt as to whether, in fact, the combination of nitrogen and silicate fertilization can increase yield and post-harvest yield in rainfed rice. The objective of this study was to investigate the effect of silicate and nitrogen fertilization on the development, quality, yield and post-harvest yield of rice cultivated in the rainfed environment. A field experiment was carried out in the 2014/2015 harvest in a 4 × 4 randomized block design with four replications. The first factor corresponded to the nitrogen doses (0; 50; 100 and 200 kg ha-1 of N), in the form of urea, and the second factor at silicon doses (0; 7.5; 15 and 30 kg ha-1 Si), in the form of calcium silicate. Si affected the chlorophyll content at 45 days after sowing (DAS) suggesting being important in floral differentiation. The increase in N doses caused higher levels of chlorophyll in rice leaves at 55, 65 and 85 DAS, regardless of whether they supplied Si. Plant height, number of tillers, weight of one thousand seeds, total grain yield and of whole grains were not influenced by the Si supply. However, Si doses reduced the yield of broken grains, thus reducing postharvest losses and, consequently, improving grain quality in the beneficiation process.

“…The valuable influences of intercropping in ameliorating biodiversity, heightening farmland ecosystem balance, and diminishing the occurrence of harmful organisms have been well documented (LaMondia et al, 2002;Ning et al, 2017). The soil microbial community is a fundamental component of soil quality and is imperative for many ecological processes, such as energy flow, nutrient cycling, and organic matter turnover (Acosta-Martínez et al, 2008).…”

Intercropping of cereals and legumes has been used in modern agricultural systems, and the soil microorganisms associated with legumes play a vital role in organic matter decomposition and nitrogen (N) fixation. This study investigated the effect of intercropping on the rhizosphere soil microbial composition and structure and how this interaction affects N absorption and utilization by plants to improve crop productivity. Experiments were conducted to analyze the rhizosphere soil microbial diversity and the relationship between microbial composition and N assimilation by proso millet (Panicum miliaceum L.) and mung bean (Vigna radiata L.) from 2017 to 2019. Four different intercropping row arrangements were evaluated, and individual plantings of proso millet and mung bean were used as controls. Microbial diversity and community composition were determined through Illumina sequencing of 16S rRNA and internal transcribed spacer (ITS) genes. The results indicated that intercropping increased N levels in the soil–plant system and this alteration was strongly dependent on changes in the microbial (bacterial and fungal) diversities and communities. The increase in bacterial alpha diversity and changes in unique operational taxonomic unit (OTU) numbers increased the soil N availability and plant N accumulation. Certain bacterial taxa (such as Proteobacteria) and fungal taxa (such as Ascomycota) were significantly altered under intercropping and showed positive responses to increased N assimilation. The average grain yield of intercropped proso millet increased by 13.9–50.1% compared to that of monoculture proso millet. Our data clearly showed that intercropping proso millet with mung bean altered the rhizosphere soil microbial diversity and community composition; thus, this intercropping system represents a potential mechanism for promoting N assimilation and increasing grain yield.

“…Intercropping reduces the climate-driven crop failure as variety of crops have different climatic adaptability (Shava et al 2009). Intercrops efficiently utilize the natural resources such as land, light, water and nutrient and increase biodiversity, productivity, resilience and stability of agroecosystem (Zhang and Li 2003;Mushagalusa et al 2008;Ning et al 2017). Analysis of long-term experiments indicated that increasing crop rotation intensity from single crop (corn) to double crop (corn-soybean) enhanced carbon sequestration by 20 g cm −2 year −1 in humid continental climate at Wooster of Ohio, USA (West and Post 2002).…”

Sustainable food production is one of the major challenges of the twenty-first century in the era of global environmental problems such as climate change, increasing population and natural resource degradation including soil degradation and biodiversity loss. Climate change is among the greatest threats to agricultural systems. Green Revolution though multiplied agricultural production several folds but at the huge environmental cost including climate change. It jeopardized the ecological integrity of agroecosystems by intensive use of fossil fuels, natural resources, agrochemicals and machinery. Moreover, it threatened the age-old traditional agricultural practices. Agriculture is one of the largest sectors that sustain livelihood to maximum number of people and contribute to climate change. Therefore, a climate-smart approach to sustainable food production is the need of hour. Traditional agriculture is getting increased attention worldwide in context of sustainable food production in changing climate. The present article advocates traditional agriculture as a climate-smart approach for the sustainable food production and also deliberates the correlation between climate change and agriculture.
