Compost tea, Tilt 250 EC and Bavistin 50 WP were evaluated for controlling brown spot and narrow brown spot diseases of rice in the field laboratory of the Department of Plant Pathology, Bangladesh Agricultural University, Mymensingh during the period from July to December, 2011. Significant effect of different treatments was observed on the severity of brown spot and narrow brown spot of rice as compared to control. The results evidently showed the lowest brown spot severity in T4 (Tilt 250 EC applied as foliar spray) which was statistically similar to T3 (Compost tea as soil drenching) while the highest severity was recorded in untreated control plot at booting and ripening stage. But narrow brown spot severity was lowest in T4 (Tilt 250 EC as foliar spray) which was similar to T5 (Tilt 250 EC as soil drenching), T6 (Bavistin 50 WP as foliar spray) and highest severity was found in T2 (Compost tea as foliar spray) which was statistically similar to T1 (control), T3 (Compost tea as soil drenching), T7 (Bavistin 50 WP as soil drenching) at booting stage. But at ripening stage the highest severity was found in T1 (control) and the lowest severity was found in T4 (Tilt 250 EC as foliar spray) which was statistically similar to T5 (Tilt 250 EC as soil drenching). However, soil drenching and foliar application of compost tea performed better as compared to control in reducing the severity of brown spot. But compost tea as foliar spray increased the narrow brown spot disease. Significant effect of the treatments was observed on growth and yield contributing characters except panicle length. Foliar and soil application of Tilt and soil application of compost tea showed better performance in increasing growth and yield contributing characters as compared to all other treatments.Bangladesh J.

Rice is a rich accumulator of silicon and its supply is essential for the growth and economic yield of rice. Hence, a field experiment was conducted in sandy clay loam soil belonging to Padugai series (Typic ustifluvent) at farmers holding in Kuttalam block, Mayiladuthurai district, Tamil Nadu to assess the role of silicon in improving agronomic characters and yield of rice ADT 43, Oryza sativa. The treatments included  T1 -  Recommended dose of fertilizer (RDF), T2 - RDF + Potassium silicate (FS) - 0.25%, T3- RDF + FS - 0.50%, T4 - RDF +FS - 1.00%, T5­ -RDF + FS - 0.25%, T6 - RDF + FS - 0.50%,  T7­ - RDF + FS - 1.00%,  T8 - RDF + SA - 50 kg ha-1, T9 - RDF + SA - 100 kg ha-1 and T10 - RDF + SA- 150 kg ha-1. From T2 to T4, the foliar spray was done at tillering stage and from T5 to T7, the foliar spray was done at tillering and panicle initiation stage.  The silicon was applied through FS with the rice crop. The soil application of silicon relatively recorded higher growth and yield compared to foliar application. Besides improving different agronomic characters of the rice, the soil application of 50 kg Si ha-1 registered the highest grain yield (6183.3 kg ha-1) and straw yield (6740 kg ha-1) and was comparable with a single foliar spray of 1% Si.  Growth and rice yield increased with Si concentration of 0.25% to 1%.  Thus, the soil application of silicon @50 kg ha-1 through potassium silicate is advocated to realize maximum rice yield.

This study was carried out with a view to evaluating the effect of foliar application of urea on BRRI dhan29. The experiment was laid out in a RCBD design with seven treatments (T1 : Full dose of prilled urea @ 140 Kg N ha-1) (control), T2 (50% prilled urea + 5 foliar spray @ 0.5% N solution @ 5.5 kg N spray-1),T3 (70% prilled urea + 3 foliar spray @ 0.5% N solution @ 5.5 kg N spray-1), T4 (50% prilled urea + 3 foliar spray @ 1.0% N solution @ 11 kg N spray-1), T5 (50% prilled urea + 5 foliar spray @ 0.5% N solution @ 5.5 kg N spray-1 + 5 t ha-1 cow dung), T6 (70% prilled urea + 3 foliar spray @ 0.5% N solution @ 5.5 kg N spray-1 + 5 t ha-1 cow dung) and T7 (50% prilled urea + 3 foliar spray @ 1.0% N solution @ 11 kg N spray-1 + 5 t ha-1 cow dung) and three replications. Soil and foliar application of nitrogen significantly influenced the growth and yield contributing characters like plant height, panicle length, and effective tillers hill-1 as well as the grain and straw yields of the crop. The treatment T5 produced the highest grain yield (6.68 t ha-1) which was statistically similar to yield from T7, T6. Treatment T2,T3 and T4 gave similar yield. The grain yields of these treatments were higher than those of T1 treatment (soil application of urea only). The T5 also produced the highest straw yield of the crop. The lowest grain yield of 4.72 t ha-1 and the lowest straw yield of 5.17 t ha-1 were recorded with T1 (control).Res. Agric., Livest. Fish.3(1): 79-85, April 2016

Aim: To determine the impact of soil and foliar application of ZnSO4.7H2O at late stages of wheat as heading initiation (5% ear formation), 100% heading (complete ear formation) and heading initiation and 100% heading along with recommended dose of fertilizer on growth, yield and quality of zero till wheat. Methodology: The field experiment was conducted on zero till wheat. The treatments consisted of control (no Zn), soil application of 12.5, 25, 37.5, 50 kg ha-1 ZnSO4.7H2O and foliar application of 0.5% Zn as one spray at heading initiation (5% ear formation), one spray at 100% heading (complete ear formation) and two sprays at heading initiation and 100% heading with recommended dose of fertilizer. These treatments were evaluated in RBD with three replications. Results: Soil application of 50, 37.5 and 25 kg Zn ha-1 with two foliar sprays of 0.5% at heading initiation (5% ear formation) and 100% heading (complete ear formation) stages gave significantly higher average grain and straw yield and Zn concentration in grain than other treatments, including control. Interpretation: Enhanced application of Zn as soil and foliar application ameliorates soil Zn deficiency and increases protein content in grains, which might influence the quality and yield of zero tilled wheat. Key words: Foliar spray, Grain yield, Wheat, Zinc

A field experiment was conducted during the summer, 2014 at College of Agriculture, Vellayani, Kerala to evaluate the influence of irrigation levels, nitrogen stress and method of application of fertilizers on growth and yield of yard long bean. The experiment consisted of four levels of irrigation, two levels of nitrogen and two methods of application. The results indicated that daily irrigation at 10 mm depth and recommended dose of nitrogen (30 kg ha-1) recorded superior values for growth parameters viz., functional leaves per plant and leaf area index The major yield attributes like number of pods per plant and pod yield per plant and total pod yield were not influenced by levels of irrigation and nitrogen indicating that irrigation once in three days at 20 mm depth and nitrogen level of 22.5 kg ha-1 is sufficient for yard long bean. Soil and foliar application of nitrogen and potassium recorded superior growth characters, however, the yield was superior when the recommended dose of nutrients were supplied as soil application. Increasing irrigation interval to three days and imparting N stress did not result in any reduction in gross income and net income while, a higher benefit: cost ratio was noted in irrigation at wider intervals. Soil application of nutrients recorded higher gross income, net income and BCR compared to soil + foliar application.

The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh during the period of 2019-2020 and 2020-2021 to investigate the effect of vermiwash on growth, yield and quality of brinjal and to find out suitable foliar dose of vermiwash for optimizing the yield of brinjal. There were five treatments comprising T1= Chemical fertilizer (CF) + foliar spray of distilled water (control), T2 = CF + foliar spray of 10% vermiwash, T3 = CF + foliar spray of 20% vermiwash, T4 = CF + foliar spray of 30% vermiwash and T5= CF + foliar spray of 40% vermiwash. Results revealed that, vermiwash treated brinjal plants showed better growth and yield parameters than the control plants. The highest average brinjal fruit yield (29.99 t ha-1) was found in T3 treatment i.e., foliar spray of 20% concentration of vermiwash and the lowest (26.35 t ha-1) came from control. On the other hand, nutritional quality (moisture content, TSS, β carotene and nutrient content) were seen to be higher in vermiwash treated treatment compared to control treatment. The study suggests that, 20% concentration of vermiwash could be used as effective foliar spray for eco-friendly and higher yield of brinjal.

Experiments were carried out at the student’s experimental field, Kabba College of Agriculture, Horticulture section to examine the effect of soil application of cow dung combined with foliar application of boost extra on growth and yield of okra in an ultisol, Nigeria. The land was ploughed each year and harrowed with the aid of tractor mounted implements. The experiment was laid out in a randomized complete block design (RCBD). The treatments consisted of A = 3t/ha cow dung, B = 1.0 L/ha foliar + 2.5t/ha cow dung, C =1.5L/ha foliar + 2t/ha cow dung, D    = 2 L/ha foliar      + 1.5 t/ha cow dung, E = 2.5L/ha foliar + 1.0t/ha cow dung, F = 3t/ha foliar. Each year experiment was conducted using a single field having dimension of 35 by 14m which was laid out into three blocks with 1m guard row between blocks. Each block consists of six plots (5 by 4m) and 1m guard row between plots. Cow dung manure was applied a week before planting. Okra variety Lady’s finger was used. Three seeds per hole were planted on April 4th in both years on the flat with a spacing of 60cm x 25cm between and within the rows and later thinned to one plant per stand. Data taken included plant height at 50 % flowering, number of branches per plant, leaf area, pod length, pod diameter, number of pods per plant; and pod weight and yield (t/ha). The data were subjected to Analysis of Variance (ANOVA) while the Least Significant Difference (LSD) was used to separate treatment means. The result shows that plot treated with 2.0L/ha foliar + 1.5 t/ha cow dung had the best performance in yield and yield components in this study. It is therefore recommended that okra farmers should integrated foliar fertilizer (boost extra) at the rate of 2L per hectare with cow dung at rate of 1.5t per hectare be used for okra production in the study area.

Foliar Application seems to be an upcoming and ongoing research area especially in the field of agriculture. This is been in practice in various parts of the world and proved its positive results in its field [1,2]. Foliar application can be explained as spraying the suitable fertilizer solution (condition is, that it should be water soluble) on the surface of the leaves of growing plants [3]. This practice not only saves quantity of fertilizer used but also improves the uptake of a particular micronutrient by the crops and boosts the yield too. Interaction between crop’s genetic potential and the environment in which it grows is detrimental for the yield of a crop [4]. Soil application of nitrogen is a conventional method to supply nitrogen to plants and for improvement in any field adhering to the old ways will not be a better option [4]. In some instances, the availability of urea becomes inadequate for the farmers at sowing time. In such situation the foliar application of plant nutrient is effective and economical for some crops [5]. It has been shown in some studies that uptake of micronutrients directly from plants is more rapid and quicker for better results in yields than soil application[1]. As mentioned above, that the fertilizer should be water soluble for foliar spray and moreover, it should also be noted that the particular crop plant also should be suitable for aerial spray. The best results of foliar application also depends on the soil condition as if soil conditions are unfavourable when micronutrients are needed, it may be desirable to make foliar applications of the plant nutrients

Objective of this study was to examine and evaluate the role of different rates of salicylic acid (SA) as foliar spray on growth and yield performance of BRRI dhan29. The experiment was conducted at Sher-e-Bangla Agricultural University, Bangladesh from November, 2016 to May, 2017 following a randomized complete block design with five rates of SA in six replications. The results showed that the lower rate of SA (upto 0.75 mM) has a positive effect on rice biomass production including effective tiller per hill, filled grain per panicle, grain yield and straw yield. The highest dry matter production at both maximum tillering and panicle initiation stages was found at SA spray rate of 0.5 mM. The highest number of effective tillers per hill (14.7) as well as the highest filled grain (120.4) and grain yield (8.1 t/ha) were found at SA rate of 0.75 mM. However, the maximum biomass production was obtained at SA rate of 0.25 mM. The minimum grain yield (7.0 t/ha) was observed in the control treatment.

Nitrogen and micronutrients have a key role in many citrus plant enzyme reactions. Although enough micronutrients may be present in the soil, deficiency can develop due to soil depletion or the formation of insoluble compounds. The objectives of this study were to (1) determine the adsorption, distribution, and availability of Zn in a sandy soil; (2) compare the effectiveness of foliar and soil application methods of Zn on Huanglongbing [HLB] affected trees; (3) compare foliar application rates of Zn for HLB-affected trees; (4) determine the effect of N rates on yield, soil inorganic N distribution patterns, and tree growth parameters. Tree rows were supplied with three N rates of 168, 224 and 280 kg·N·ha−1 and Zn at single and double recommended rates (recommended rate = 5.6 kg·Zn·ha−1) using foliar and soil application methods, in a split-plot experimental design. The results show that Zn concentration in the 0–15 cm soil depth was three times higher than the 30–45 and 45–60 cm soil depths during the study. An adsorption study revealed high Zn (KD = 6.5) sorption coefficients at 0–15 cm soil depth, while 30–45 and 45–60 cm depths showed little sorption. Leaf Zn concentration for foliar spray was two times higher than the soil application method. A nitrogen level of 224 kg N ha−1 improved canopy volume when compared to other N levels at the expense of reduced fruit weight. Foliar Zn application at 5.6 or 11.2 kg ha−1 and N rate at 224 kg ha−1 appear to be adequate for improving the performance of HLB-affected citrus trees.
