We compared the quantity-intensity (Q/I) relationships for K+ under conventional tillage and no-tillage systems in tropical paddy fields in the absence and presence of K+ fertiliser in the addition of nitrogen. The results showed that the values of the activity ratio for K (ARK) and potential buffering capacities (PBCK) in the no-tillage rice field were respectively 16% and 33% higher than that in the conventional tillage field. With the addition of K fertiliser, the value of exchangeable K in equilibrium (ΔK0) in the no-tillage paddy field was 67.9% greater than that in the conventional tillage field. This indicates that K fertilisation is more efficient when applied on a no-tillage paddy field. When the K fertiliser was added (49.8 kg K/ha), the application of N fertiliser at the rate of 115 and 184 kg N/ha resulted in a higher ARK value than that at the rate of 46 kg N/ha. This suggests that the simultaneous application of K and N fertiliser was able to increase exchangeable K in the soil. The application of no-tillage increased of the dry grain yield of rice (about 10%) compared with the application of conventional tillage. Meanwhile, there were significant relationships between the rice yield with the ARK and ΔK0. Moreover, the ARK was significantly correlated with K-uptake.

However, little is known about the correlation between NFB application on growth and yield components of rice plants on saline soils. Exploration and experimental methods were performed to obtain the potential of NFB from a rice field in saline soil and reinoculated in a pot experiment. The experiment was arranged as a randomised block design consisting of 8 treatments, namely inoculation application (control and seed treatments with 20 g inoculant/kg of seed) combined with soil application dosage (0, 500, 1 000 and 1 500 g/ha). The results showed that grain yield increased by 43.8-130.6% with seed treatment of 20 g inoculant/kg of seed combined with soil application 500-1 500 g inoculant/ha. Rice yield was affected by multiple variables NFB population, plant height, number of tillers, and grain straw ratio (R2 = 0.926). Path analysis findings showed that the greatest effective contribution (45.45%) yield of rice in saline soil was contributed NFB population. This finding concludes that the application of NFB inoculants as seed treatments and soil applications can serve as an effective as well as the environmentally friendly microbial-based strategy of rice cultivation on saline soil ecosystems.

China Title: Adaptation analysis of insect-resistant transgenic line after introducing mcry1F gene in maize Abstract: The ability to adapt, survive, and compete with weeds of transgenic plants is the necessary evaluation content to release transgenic lines in target regions. We compared weediness and agronomic traits of transgenic maize lines G1F-8 and G1F-19 carrying the mcry1F gene with their near-isogenic maize inbred line Zheng 58 in the wasteland and cultivated field under natural conditions for two consecutive years. The results showed that there was no significant difference identified in the species, quantity, and relative coverage ratio (RCR) of weeds between fields with G1F-8, G1F-19, and Zheng 58, regardless of the sowing pattern in the wasteland. Compared with the vigour of weeds, none of G1F-8, G1F-19, and Zheng 58 showed survival advantages, and all showed weak growth potential with no final grain yield. Meanwhile, no volunteer seedlings were found upon investigation in the following year. The simulated seed overwintering experiment in the wasteland further showed that the three kinds of maize could not germinate in the second year. In cultivated land, G1F-8 and G1F-19 had the same growth stages, plant height, and RCR as Zheng 58 throughout two years. In conclusion, the transgenic lines G1F-8 and G1F-19 exhibited no adaptability risk in Gongzhuling, Jilin, China.

China Title: Combined effect of nitrogen and phosphorous fertiliser on nitrogen absorption and utilisation in rice Abstract: The objectives of this study were to investigate the nitrogen (N) and phosphorus (P) balance fertilization strategy in paddy fields, and to evaluate the effects on N uptake and utilization in rice. In 2017-2018, the experiment was conducted using Deyou4727 hybrid rice with four different P fertilizer levels (0, 30, 60, and 90 kg/ha), marked as P0, P1, P2, P3 in turn, and four different N levels (0, 90, 150, and 270 kg/ha), similarly marked as N0, N1, N2, N3 in turn. The results showed that in the N-insufficient (N0, N1) environments, the P1 treatment increased N uptake and promoted transfer to the grain. However, high-P (P3) application increased the dry matter accumulation than other P levels, but limited the production and translocation of dry matter to some extent. In N-sufficient (N2, N3) environments, P2 level increased crop yield and N use efficiency by 11.35% and 37.01%. Unlike P2, none-P (P0) and high-P levels decreased rice dry matter translocation and transport capacity, which further affected N uptake and utilization in N-sufficient environments. Overall, the combination of the N application rate of 90 kg/ha and P application rate of 30 kg/ha, N application rate of 150, 270 kg/ha, and P application rate of 60 kg/ha had a high yield; strong nutrient accumulation and transfer ability. It was more inclined to balance N and P, which was beneficial to plant N absorption and utilization.

To this end, soil fertilised with the spent mushroom substrate (SMS) or with an anaerobic digestate (DIG) was subjected to an incubation assay, and the results were compared with those from soil treated with a mineral fertiliser (MIN) and an unfertilised soil (CO). The soil was sampled after fertilisation and after 90 days of aerobic incubation. Nitrogen (N) mineralisation (NH4+ and NO3-) and oxidable carbon (OC) were determined. The impact of the treatments on the soil was evaluated by measuring the enzymatic activity of arylsulfatase (ARYL), ß-galactosidase (GAL), and urease (URE). The highest OC content was observed in the SMS treatment. After 90 days of incubation, the SMS treatment showed a lower mineral N content than the CO treatment. This finding was associated with N immobilisation. However, mineral N significantly increased ARYL activity in the DIG and MIN treatments, and URE activity was always higher at both sampling times in the SMS treatment. Initially, GAL activity was notably high in the DIG treatment but decreased after incubation, reaching similar values to those registered in the CO treatment. Organic fertilisation treatments induced different effects on soil N mineralisation, showing changes in the activity of the enzymes analysed.
