Abstract/ Executive Summary:

A field experiment was conducted at Bangladesh Rice Research Institute, Comilla ( N 23.66653 & E 91.15887), Bangladesh, to investigate the effect of foliar application of silicon on yield and quality of medium fine grain rice (Oryza sativa L.). The research was designed as randomized complete block design (RCBD) having three replications and 6m x 5m net plot size was maintained. Foliar applications of silicon’s aqueous solution were used as treatments comprised of control, 0.25%, 0.50%, 1.00% silicon solutions. Nursery of 28 days old seedling nursery was transplanted to the plots under aerobic condition and 20 cm hill to hill distance was maintained. Sodium silicate (9.93% Si) as the source of silicon (soluble in warm water) was used. Fertilizer inputs as nitrogen, phosphorus, potassium, Sulfur and Zinc were uniformly applied at the rate of 194, 97, 97, 39 and 4.5 kg ha^-¹ while all other agronomic practices were kept constant for all the treatments. The data from the field (yield components) as well as lab analysis (quality parameters) was recorded according to the standard procedures. Fisher’s analysis of the variance technique was used for statistical analysis and treatment’s mean differences were compared using least significant difference (LSD) test at 5% probability level. Silicon showed no significant effect on plant height, harvest index, number of kernels and opaque kernels percentage. Silicon (1.00% silicon solution) produced maximum grain diameter and silicon (0.50% silicon solution) produced maximum grain protein while silicon @ 0.25% silicon solution resulted maximum in number of productive tillers, straw yield, branches per panicle, grains per panicle, 1000 grain weight, paddy yield and grain starch. All others parameters have overlapping results of different silicon levels.

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer

Objectives:

The main objective was to evaluate the effect of foliar application of silicon on yield and quality of rice

Methodology:

Experiment was conducted at Bangladesh Rice Research Institute, Cumilla, Bangladesh, on clay-loamy soil during 2015-16. BRRI dhan49 (medium fine rice) was the crop to investigate the effect of foliar application of silicon on yield and quality of rice. Randomized complete block design having three replications was used and net plot size 6m x 5m was maintained. The replications were considered as blocks. Before cultivation soil analysis according to standard procedure was performed. Treatments included in the experiment were as following, Si0 = 0.00, Si1 = 0.25, Si2 =0.50, Si3 = 1.00 in percentage (%) silicon aqueous solutions. Nursery of 28 days old seedlings was transplanted to the puddle field; two/three seedlings per hill at 20 cm distance. Silicon was applied after 4 weeks of transplantation as foliar spray. Fertilizers as N, P K,S and Zn were applied at the rate of 194, 97, 97, 39 and 4.5kg ha^-1, respectively. Whole of phosphorous, potassium (muriate of potash), sulfur and zinc were applied before transplantation while nitrogen (urea) was applied in three splits, one-third (1/3) of urea was applied during transplanting whereas one-third (1/3) was applied at tillering stage and one-third (1/3) was applied at the time of panicle initiation. Irrigation was applied one week prior to nursery transplantation.The data on different agronomic traits and quality parameters were collected and subjected to one way analysis of variance according to Steel et al. (1997) to sort out significant differences among treatments. Differences among means were compared using LSD at 5% probability level.

Achievement/Findings:

From above the results the following conclusion was observed during the experiment. Plant height, number of tillers per plant, number of productive tiller, abortive kernel performed better where control silicon was applied, while straw yield, branches per panicle, spike per panicle, 1000 grain weight, paddy yield, grain starch were performed better where 0.25% silicon was applied by foliar application.
