“…Although DE OLIVEIRA et al (2016) found negative effects of silicon on the profiling and on the number of panicles in rice plants, possibly due to the higher absorption of silicon and lower absorption of phosphorus and nitrogen, favored by chemical similarity (460 and 490 mg dm -3 Si), there may have been higher absorption of silicon and less absorption of these two elements, which are essential for lamination and panicle formation. This subject is worthy of further study at the soil chemistry level.…”

Silicon (Si) is not considered an essential element for plant growth and development. However, in many agricultural soils, are deficient in plant-available Si, making Si supplementation necessary. We assessed the effect of silicon and nitrogen fertilization on the water use efficiency (WUE) of sugarcane, planted on a soil classified as Typic Hapludox (Eutrophic Red Latosol in Brazil), the plants were grown within 11 L pots in greenhouse at the Department of Biosystems Engineering, ESALQ/USP, Brazil. The experimental design was completely randomized with 4 blocks with 8 treatments in a factorial scheme (2 x 3)+ 2, made up by two levels of nitrogen (N) (0,6 and 0,9 g pot -1 ) and three levels of Si (5, 10 and 15 g pot -1 ). The results were submitted to analysis of variance by the Test F and the differences between the treatments were compared by at 5% of significance. Our results indicate that high levels of N combined with Si do not improve the efficiency of water use in sugarcane.KEYWORDS: ammonium, cement, sugarcane. EFEITO DO NITROGÊNIO E DO SILÍCIO SOBRE

“…Generally, continued water deficit conditions until the reproductive stage may result in a loss of physiological activity and water absorption, which may have severe consequences on rice yield formation. Increased soil water deficit from 0 to −60 kPa reduced grain numbers and seed setting rate (higher sterility percentage) in rice (Oliveira et al, 2016). Thus, variations in water regimes at anthesis and/or grain filling stages possibly reduced the filled grain %, 1000‐grain weight, and yield in rice.…”

Alternate wetting and drying (AWD) has been recognized as a water‐saving technology in rice production systems; however, pre‐ and post‐flowering AWD could induce changes in yield, quality and aroma biosynthesis in fragrant rice. In the present study, two fragrant rice cultivars (Guixiangzhan and Nongxiang‐18) were subjected to AWD till soil water potential reached −25 to −30 kPa during vegetative stage (VS), reproductive stage (RS), and both stages (VS + RS). The AWD did not affect net photosynthesis and gas exchange significantly, while malondialdehyde (MDA), H2O2 and electrolyte leakage (EL) were higher than in control plants. The AWD treatments variably affected soluble sugars, proline and protein accumulation as well as the activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), ascorbate peroxidase (APX), and reduced glutathione (GSH) contents. Moreover, filled grain percentage and 1000‐grain weight in AWD treatments were found to be statistically similar (p > 0.05) to control, except grains panicle−1 under AWD‐VS + RS that was reduced by 11% and 14% for Guixiangzhan and Nongxiang‐18, respectively. On average, yield and related attributes in Guixiangzhan remained higher than in Nongxiang‐18. In addition, the grain aroma volatile (2‐acetyl‐1‐pyrroline, 2‐AP) content increased by 8.79%, 14.45%, and 6.87% and 7.95%, 14.02%, and 5.04% under AWD‐VS, AWD‐RS, and AWD‐VS + RS treatments, for Guixiangzhan and Nongxiang‐18, respectively. Overall, AWD treatments, either at VS or RS, could promote rice aroma in terms of accumulation of 2AP, which might be linked with enhanced endogenous proline contents (a precursor for 2AP biosynthesis) without any severe consequences on rice yield and quality.

“…Most research on the application of Si to improve growth and production has used synthetic inorganic material. Some materials commonly used as sources of silicon fertilization to plants are calcium and magnesium silicate (Camargo et al, 2013), sodium silicate (Azizi et al, 2016), silicon dioxide (SiO2) with 95 % silicon (Oliveira et al, 2016), and other inorganic materials. In this research, natural materials such as zeolite and sugarcane bagasse compost ( SCB) were used as sources of silicon because they are abundant in Indonesia (Yustinah, 2013) and are capable of improving the productivity of entisol soil.…”

Silicon is a beneficial nutrient that has the potential to alleviate the abiotic stress of bok choy grown under salinity stress on entisols. Indonesia has wide areas of entisol soils along its coastline, which could be planted with bok choy. However, salinity conditions pose a problem in entisol soils. The objective of this research was to evaluate the effect of silicon on the agronomic performance of bok choy grown on an Entisols under salinity stress conditions. This research was conducted at the screen house of the Faculty of Agriculture, Jenderal Soedirman University, from May to August 2019. The experimental design was a completely randomized completely block design (RCBD) consisting of 16 treatments with three replications. The treatments comprised two factors: the dosage of silicon fertilizer, which was 0, 5, 10, or 15 g pot-1; and salinity stress, with a level of 0, 1, 2, or 3 dS m-1 pot-1. Observed variables included plant height (cm), number of leaves (strands), leaf area (cm2), fresh shoot weight (g), dry shoot weight (g), fresh root weight (g), dry root weight (g), fresh plant weight (g), and dry plant weight (g). The results showed that the provision of silicon (Si) fertilizer from zeolite and sugarcane bagasse compost (SCB) improved plant height, number of leaves, leaf area, fresh plant weight, and dry plant weight of bok choy plants under salinity stress conditions on entisol soil. At a silicon dosage of 10 g pot-1, fresh plant weight (production of bok choy) was 64.18% greater compared to the control. Increasing soil salinity up to 3 dS m-1 of soil decreased the plant height and number of leaves but did not significantly affect fresh shoot weight, dry shoot weight, fresh plant weight, dry fresh plant weight, fresh root weight, or dry root weight.
