“…Provinces, the rice cropping system, precipitation, temperature, planting area and grain yield under all rice production regions are detailed in Table 7. SC, SYR, MLYR and SW regions have more precipitation with the great potentiality of maintaining and expanding the paddy field for irrigated lowland rice, while in NC and NE China, because of the scarcity of precipitation, the cropping system of aerobic rice becomes more and more attractive, specially, for SC regions increasing serious shortage of freshwater resource (Tong et al 2003;Dai et al 2009).…”

As one of the staple food crops，rice (Oryza sativa L.) is widely cultivated across China, which plays a critical role in guaranteeing national food security. Most previous studies on grain yield or/and nitrogen use efficiency (NUE) of rice in China often involved site-specific field experiments, or small regions with insufficient data, which limited the representation for the current rice production regions. In this study, a database covering a wide range of climate conditions, soil types and field managements across China, was developed to estimate rice grain yield and NUE in various rice production regions in China and to evaluate the relationships between N rates and grain yield, NUE. According to the database for rice, the values of grain yield, plant N accumulation, N harvest index (HI N), Indigenous N supply (INS), internal N efficiency (IE N), reciprocal internal N efficiency (RIE N), agronomic N use efficiency (AE N), partial N factor productivity (PEP N), physiological N efficiency (PE N) and recover efficiency of applied N (RE N) averaged 7.

“…Nitrogen deficiency reduces the uptake of P and K, S and many other nutrients in crop plants (Das and Sen, 1981;Adams, 1980;Terman et al, 1977). N omissions reduced the uptake of N, P and K in aerobic rice and wheat in rice-wheat cropping system (Dai et al, 2010). The drop in S and Zn concentrations in the stalk and seed in S and Zn omission plots was not so severe indicating more or less constant soil supply of these nutrients over three seasons.…”

A field experiment on nutrient omission plot technique (NOPT) on Bt cotton-wheat cropping system was conducted at research farm of the Division of Agronomy Indian Agricultural Research Institute, New Delhi during rainy season of 2010 and 2011. The experiment had 10 treatments, laid out in Randomized Block Design with three replications in fixed plots. Treatments comprised omission of N, P, K, S and Zn, 50% omission of N, P, and K, absolute control (no nutrient applied) and optimum plane of nutrition (150-26.4-50-15-3 kg ha-1 N-P-K-S-Zn). Same nutrient omission treatments were tested on wheat keeping the plots fixed. Yield was estimated in terms of seed cotton, lint, seed and oil yield. The uptake of nutrients in omission plots gave an estimate of the indigenous soil nutrient supply and nutrient use efficiencies. Results showed that N was the most limiting factor nutrient and there was a reduction in the seed cotton yield to the tune of 28, 6.5 and 14.5% due to N, P and K omissions during the year 2010. The corresponding figures for the year 2011 were 26.5, 15.5 and 12.4%, respectively. N continued to be the most limiting nutrient followed by P and K during the year 2011. P omission led to the higher yield reduction during the second year of experimentation which proves that P supplies fast depleted in the cotton-wheat cropping than the K supply. Lint yield followed similar trends. The yield reduction due to S and Zn omission ranged from 2.0 to 5.0% which was statistically at par with the plots under balanced fertilization both the years.

“…This was mainly due to the decrease in NH 4 -N in the drained fields. On the one hand, in flooded rice with saturated anaerobic soils, ammonium is the dominant form of available N which often was oxidized to nitrate in drained aerobic soils (Dai et al, 2010). And nitrate easily directly lost with water flow and denitrified as N 2 O emission to atmosphere in drained fields (Yuan et al, 2016).…”

a b s t r a c t a r t i c l e i n f oSoil microorganisms are the main drivers of all of the biochemical processes that occur in soils. Land-use conversion, a common occurrence driven by market economy, changes plant species and the associated management strategies, thus significantly influences soil microbial communities. However, few studies have been conducted to disentangle the effect of the alteration of plant species from that of soil environment during the initial years of conversion. In this study, the effect of land-use conversion from double rice cropping (RR) to maize-maize (MM) and soybean-peanut (SP) double cropping systems on soil physical and chemical properties and microbial communities was studied two years after the conversion in southern China. The results showed that land use conversion significantly changed the soil properties, microbial communities and microbial biomass. The soil water content decreased significantly by 26.3%, and the pH decreased by 0.50 and 0.52 for MM and SP, respectively, compared with RR. Soil inorganic N also decreased significantly by 55% after the conversion to drained fields. The total phospholipid fatty acids (PLFAs), and bacterial, G+, G− and actinomycetic PLFAs decreased significantly after the conversion. No significant differences were found in the soil properties, microbial communities and microbial biomass between the converted MM and SP. Our results indicated that the changes of anaerobic to aerobic conditions, rather than of crop type, induced the variations in the soil properties and microbial communities during the initial years after conversion from paddy soils to drained soils. In particular, soil pH was the key factor that regulated the variations in the soil microbial communities after conversion.
