“…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.

“…Also, Silicon can enhance antioxidant defense and then decrease oxidative stress in plants under drought, and it can increase the photosynthesis and relevant carboxylase activities, as found in wheat by Gong and Chen, (2012). Also, Pilon et al (2013) found that silicon application increased leaf area and chlorophyll concentration of well-watered potato plants, improved plant growth parameters and pigment concentration of wheat, (Maghsoudi et al (2015) and rice Oliveira et al (2016). 3.3.…”

Two field experiments were carried out during the growth seasons of 2017 and 2018 at the Experimental Farms of Mallawy Agriculture Research Station, Hort. Res. Institute, Giza, Egypt to evaluate the effect of vine cutting ages and potassium fertilizer sources on the growth of the sweet potato cv "Mabrouka". The treatments comprised three apical vine cuttings ages (3, 5 and 7days) as well as fresh cutting (control treatment) and four sources of potassium fertilizer (K-sulphate, K-silicate, K-citrate and Khumate). The obtained data revealed that: the highest survival rate of vine cuttings was achieved with the 3-days age and fresh cutting planting. The greatest sweet potato studied parameters [vine fresh weight (ton.fed -1) , storage root yield (ton.fed -1 ), biomass yield (ton.fed -1 ) storage roots length, cm), and K %] were produced with the treatment of immediate planting and 3-days old cuttings. Also, 5-days old cuttings showed the highest total number of storage roots. Contrariwise, storage root diameter, (cm) storage root dry matter (%) and marketable yield (%) were not affected by vine cuttings age in both seasons.All potassium sources which were used as foliar application affected the growth and yield parameters of sweet potato cv. "Mabrouka". The treatments of K-silicate and K-sulphate gave the best results of biomass yield (storage roots + forage weight, ton.fed -1 ), marketable yield%, and root diameter. The combined treatments of fresh cuttings and K-silicate foliar fertilizer showed the greatest values for number of storage roots, root yield, root diameter and biomass yield (ton.fed -1 ). Also, the 3-days-vine cuttings and K-humate treatment recorded the best results for vine fresh weight (ton.fed -1 ).
