Aim: To study the Influence of nutrient management on growth, lodging and yield of transplanted rice. Study Design: The study comprised of eight treatments viz.,T1- 100% NPK, T2- 100% NP + 125% K, T3- 75% N + 100% PK, T4- 75% N + 100% P + 125% K, T5- 100% NPK + K2SiO4 at 50 kg ha-1, T6- 100% NPK + Ca2SiO4 at 50 kg ha-1, T7- 100% NPK + Na2SiO3 at 50 kg ha-1 and T8- absolute control in randomized block design. Place and Duration of Study: This research trail was conducted during the late samba (September – February) of 2021-22 at Anbil Dharmalingam Agricultural College and Research Institute. TNAU, Trichy, Tamil Nadu, India. Methodology: The study consisted of combination of 8 treatments in RBD which was replicated thrice. The rice variety of IW Ponni was used for this study. The observation have been recorded during the different phases of growth at regular intervals. Results: The results revealed that the application of 100% NPK + K2SiO4 at 50 kg ha-1 has recorded significantly taller plant height (131.7 cm), higher dry matter production (11360 kgha-1), grain (4535 kg ha-1) and straw yield (7259 kg ha-1) over absolute control. Minimum bending moment and lodging score were reported with 100% NPK + K2SiO4 at 50 kg ha-1 and it was on par with 100% NPK + Ca2SiO4 at 50 kg ha-1.

“…Additionally, the study of Lavinsky et al [67] revealed an increase in the expression level of OsLsi6 when Si fertilizer was applied at the reproductive stage, potentially contributing to the higher Si levels in the rice panicles. It has also been reported that OsLsi6 functions as a Si transporter that is responsible for unloading and the distribution of Si from the xylem to accumulate in the leaf and grains [11,14,21,68]. Interestingly, a study by Wangkaew et al [28] revealed that SPR1 accumulated more Si in its transpiring organs, including the leaves and husks, and exhibited higher expression of OsLsi1, OsLsi2, and OsLsi6 compared to PTT1.…”

“…In three modes of Si uptake, it has been suggested that the active mechanisms were the best Si transport across the cell membrane [8][9][10][11]. The lateral roots uptake Si from the soil by active and passive mechanisms, then transport it passively to shoot through the xylem via a transpiration stream, where it accumulates in the cell wall of leaves, stems, and other plant tissues [5,[11][12][13][14][15] Several studies have identified genes involved in regulating Si transporters in rice that uptake and distribute Si from the root to other plant parts (i.e., the cell wall of leaves, stems, and hulls). The Si accumulation in the shoot ranges from 1.5 to 10% Si concentrations in the plant's dry weight, depending on the species [5,12,13].…”

Silicon (Si) is a beneficial nutrient that has been shown to increase rice productivity and grain quality. Fragrant rice occupies the high end of the rice market with prices at twice to more than three times those of non-fragrant rice. Thus, this study evaluated the effects of increasing Si on the yield and quality of fragrant rice. Also measured were the content of proline and the expression of the genes associated with 2AP synthesis and Si transport. The fragrant rice varieties were found to differ markedly in the effect of Si on their quality, as measured by the grain 2AP concentration, while there were only slight differences in their yield response to Si. The varieties with low 2AP when the Si supply is limited are represented by either PTT1 or BNM4 with only slight increases in 2AP when Si was increased. Si affects the gene expression levels of the genes associated with 2AP synthesis, and the accumulation of 2AP in fragrant rice mainly occurred through the upregulation of Badh2, DAO, OAT, ProDH, and P5CS genes. The findings suggest that Si is a potential micronutrient that can be utilized for improving 2AP and grain yield in further aromatic rice breeding programs.

“…Moreover, the addition of silica also enhances the uptake of NPK nutrients in shallot plants, leading to increased vegetative growth [21]. Silica deposition in cell walls can enhance the height of rice plants by making leaves and stems more erect, resulting in reduced mutual shading caused by high plant density and improving light interception, which enhances the rate of plant photosynthesis [22][23][24].…”

The Beet Armyworm (Spodoptera exigua) is a polyphagous defoliator that poses a significant threat to cultivated plants, particularly shallot crops. Its attacks during the vegetative phase cause substantial damage. To control this pest, farmers often resort to synthetic pesticides, leading to negative consequences such as resistance development. To address consequences, internal control measures, like enhancing plant resistance through beneficial nutrients like silica, are crucial. Silica has been known to improve plant resistance against pest attacks. This study aims to investigate the effects of various methods of applying nano-sized rice husk ash fertilizer on the growth and resistance of Biru Lancor cultivar of shallots against S. exigua. Nano-rice husk ash fertilizer with an average particle size of 65,326 nm was produced and applied using three methods: placement, foliar, and seed coating. The results demonstrated that all methods of nano-rice husk ash application increased plant resistance, reducing leaf damage and pest mortality. The foliar application yielded the best results, enhancing plant height and epidermal cell wall thickness. Furthermore, nano-rice husk ash application positively influenced shallot productivity. This study highlights the potential of nano-sized rice husk ash as a sustainable and effective internal control measure against S. exigua, complementing synthetic pesticides for shallot pest management.
