Effect of different sources and doses of sulphur on yield, nutrient content and uptake by spring wheat

The objective of this study was to investigate the effect of two sulphur forms (sulphate and tiosulphate) in combination with three different N:S ratios on the yield of spring wheat and total N- and S-content and uptake by the aboveground biomass on chernozem and sandy soil. In the greenhouse experiment, the effects of two sulphur forms were compared: sulphate (SO42-) and thiosulphate (S2O32-). The sulphate was applied as potassium-sulphate (K2SO4) and thiosulphate as ammonium-thiosulphate ((NH4)2S2O3). Increasing doses of both sulphur forms (24, 60, 120 kg S ha-1) were used with the same nitrogen dose (120 kg N ha-1) which caused three different N:S ratios background (1:0.2, 1:0.5, 1:1). Nitrogen was supplied in the form of monoammonium-phosphate (MAP), ammonium-nitrate and ammonium-thiosulphate. Plant samples were taken in three different development stages of spring wheat based on the BBCH scale: at the stage of BBCH 30–32 (stem elongation), BBCH 65–69 (flowering) and BBCH 89 (ripening). The total nitrogen and total sulphur content of plant at different development stages and also wheat grain were measured by Elementar Vario EL type CNS analyser. The nutrient uptake by plant and grain was calculated from the yield of spring wheat and the N and S content of plant. The grain yield on chernozem soil ranged between 6.31 and 12.13 g/pot. All fertilised treatments significantly increased the grain yield compared to the control. The highest yield was obtained in the case of the application of 120 kg N ha-1 and 60 kg S ha-1in sulphate form. The grain yield on sandy soil varied from 2.53 to 6.62 g/pot. The fertilised treatments significantly enhanced the yield compared to the control. The highest yield was observed in the case of the application of 120 kg N ha-1 and 60 kg S ha-1 in thiosulphate form. On chernozem soil the increasing doses of sulphur (24, 60, 120 kg S ha-1) with the same N dose (120 kg N ha-1) increased the N-content of spring wheat at all development stages and in the grain. The treatments with different sulphur sources did not cause further changes in the N-content. On sandy soil in the most cases the N-content did not change significantly as a result of increasing sulphur doses. The treatments with sulphate form basically resulted higher nitrogen-content than treatments with thiosulphate form. The treatments with increasing sulphur doses resulted higher S-content on both of chernozem and sandy soil in the case of all development stage. Comparing the effect of the applied sulphur sources on the S-content it can be stated that at the stage of BBCH 30–31 and 65–69 the treatments with sulphate form resulted higher sulphur-content. At the stage of BBCH 89 there was no significant differences in S-content of grain as a result of different sulphur-sources.

Mechanochemically synthesized S-ZVIbm composites for the activation of persulfate in the pH-independent degradation of atrazine: Effects of sulfur dose and ball-milling conditions

Surface passivation and an increase in pH may restrain the efficiency and capacity of the zero-valent iron (ZVI) activated persulfate (PS) process. Mechanochemically sulfidated ZVI (S-ZVIbm) shows an extraordinary increase in the activation of PS. Ball-milling avoids the complex liquid reactions of traditional methods of activation and is easier to upscale. However, the effects of the sulfur dose and milling conditions have not been sufficiently investigated in the application of S-ZVIbm to the PS activation process. S-ZVIbm was pH-independent compared with similar catalysts. The best performance was obtained for S-ZVIbm with 25% sulfur synthesized at 300 rev min−1 for 5 h. Almost complete degradation of 50 μM ATZ was obtained after 40 min reaction with 6 mM PS and 0.3 g L-1 S-ZVIbm. Structural and species characterizations revealed the effects of the milling conditions and showed that sulfide (S2−) might be the predominant sulfur species. The primary facilitation mechanisms of S-ZVIbm were the mitigation of passivation, an increase in hydrophobicity, an increase in electron transfer and the accelerated regeneration of Fe2+. 57Fe Mössbauer spectrum confirmed that the Fe0 left in S-ZVIbm was about two times higher than that in reacted ZVIbm. Fe0 acted as the predominant PS activator, but FeS2, FeS and SO32− also contributed to PS activation. The degradation pathway of atrazine was clarified based on the detection of intermediates and density functional theory calculations. S-ZVIbm is a promising catalyst for the activation of PS used to remediate refractory contaminants and is amenable to upscaling from the laboratory scale.

Pamuk bitkisinde yapraktan kükürt uygulamalarının uzun süreli su stresi koşullarında stoma iletkenliğine etkisi

Aims: This study was performed in 2015-2016 in order to determine how the foliar application of sulfur helped reduce the effects of long-term water stress in Carisma variety cotton plants in different periods of development, namely vegetative growth (VG), flowering and boll development (FB), and boll opening (BO) periods.Methods and Results: The study was set up in randomized complete block with three replications. Development periods (OOO, TTT, TOO, OTT, OTO, TOT) were assigned to main plots and sulfur doses (S0: Control, S1: 150 ml da-1, S2: 250 ml da-1, S3: 350 ml da-1) were assigned to sub-plots. Measurements were made on stomatal conductance, as well as evaporatranspiration and yield to evaluate the physiological effects of water stress. The average amounts of irrigation water used in each full irrigation were 127.5 and 138 mm respectively, for the treatment years. As for the evaporatranspiration values, in the first treatment year it was found between 304 and 1012 mm and in the second year from 256 to 1070 mm. Stomatal conductance values ranged from 269 to 1067 mmol m-2 s-1 in the first year and from 205 to 407 mmol m-2 s-1 in the second year with the highest stomatal conductance value obtained from full irrigation (TTT) during all growth periods in both years.Conclusions: The effects of sulfur dosage on stomatal conductance and yield varied due to exposure to long-term water stress at different developmental periods; however, generally speaking, the doses of S1 and S2 cause these values to increase.Significance and Impact of the Study: In the Amik Plain, there was no detailed study to determine how foliar sulfur applications changed the stomatal conductance of cotton when drip-irrigated and subjected to water stress during the different development stages. This research revealed in what dose sulfur should be given to reduce the effects of long-term water stress in Carisma variety cotton plants in Amik plain.

Multipronged approaches of KVK for enhancing agricultural production in micro-climatic conditions of the district

Krishi Vigyan Kendra Kupwara is engaged in providing timely supply of proven technologies specific to various micro-climatic locations in operational areas thus alleviating the technology fatigue existing in the district. The various extension methods like FLD, OFT, method demonstration, campaign, group discussion etc., are being employed to extend new knowledge and skill to the farmers in operational areas. The front line demonstrations on cereals (paddy, wheat, maize); oilseed crops (Brown Sarson), pulses (pea) and oats were conducted on farmers field. Under FLDs, latest components were demonstrated i.e. latest released varieties, fertilizers, date of sowing, ICM, IDM for respective crop. The yield of paddy was recorded to the tune of 64 q ha-1 demonstrating an increase of 28% in the yield as compared to local variety. The low tunnel technology demonstrated to farmers in the spring was encouraging for higher belts as there is always the possibility of dip in mercury during the preparation of nursery. The number of FLD’s under maize was highest benefitting 126 farmers covering an area of 10.8 hectares. The results depicted an increase of 111% yield and proved instrumental in improving the livelihood of the farming community. Introduction of Shalimar Wheat -1 sown during second/third week of October combined with pre-sowing irrigation had a tangible impact on yield (30q/Ha).The On- farm testing on onion, pea and cucurbits was laid in the farmers field and executed under the supervision of the scientist. The application of different doses of sulphur resulted in significant improvement in the yield and shelf life of onion. The application of sulphur @40kg /ha. recorded yield of 272q/ha and increased the shelf life more than 67 days as against control. Blanching with KMS @2g/l of solution for three minutes followed by sun drying reduced the extent of browning (5%) of dehydrated cucurbit. OFT on pea revealed that second week of October is best in terms of yield which decreased drastically by end of October sowing. Seeds may be sown when the soil has optimum moisture content for crop germination and establishment. The various technologies that were demonstrated and tested in the farmers fields of operational areas at district level showed promise and the farmers were highly satisfied with the results.

A field experiment was conducted in the Experimental Research Farm of School of Agricultural Sciences and Rural Development (SASRD), Nagaland University during the kharif season 2018. Groundnut variety ICGS-76 was sown @ 70 kg ha-1 for 60×20 cm2 spacing. The experiment was laid in split plot design with three replications. The main plot treatments consisted of two lime levels: lime @ 0 t ha-1 and lime @ 3 t ha-1 while the sub- plot treatments consisted of five sulphur levels: sulphur @ (0 kg ha-1, 10 kg ha-1, 20 kg ha-1, 30 kg ha-1 and 40 kg ha-1 along with recommended dose of fertilizer at 20:60:40 kg N, P2O5 and K2O ha-1 respectively in the form of diammonium phosphate and murate of potash. The results showed that application of lime @ 3 t ha-1 gave higher growth and yield attributes compared to no lime and also application of sulphur @ 40 kg ha-1 gave higher growth and yield attributes compared to lower doses of sulphur though there was only slight increase in the attributes between each successive doses of sulphur. Overall application of lime and sulphur increased all the yield attributes of groundnut, where the highest number of pods plant-1, seeds pod-1, 100 kernels weight, pod yield, kernel yield and stover yield were recorded when treatment was done with lime @ 3 t ha1 and sulphur @ 40 kg ha-1.

Growth and nutritional diagnosis of Rosemary plants submitted to nitrogen and sulfate fertilization

Studies on the cultivation of medicinal plants are of relevance to the population since they are primary sources of medication. Among these plants stands out the rosemary (Rosmarinus officinalis L.) for having diverse therapeutic properties. The objective of this work was to evaluate the initial growth and nutritional status of rosemary plants grown with different co’ncentrations of nitrogen and sulfur. The treatments were distributed in a 4x2 factorial scheme with four nitrogen doses: 105, 210, 315, and 420 mg L-1 of nitrogen combined with two sulfur doses: 32 and 64 mg L-1 with seven replications totaling 56 experimental units. The seedlings were obtained through asexual propagation (cuttings), originating from parent plants. The experimental units were arranged in a completely randomized design. Growth evaluations were carried out at 120 days of cultivation, using: plant height (HT) stem diameter (DS), root dry matter mass (RDM), stem dry matter mass (SDM), mass leaf dry matter (LDM), total dry matter (TDM), shoot dry matter mass (SDMS). The data obtained were subjected to analysis of variance and depending on the level of significance in the F test, the study was carried out using the means test (Tukey 5%). The agronomic characteristics (HT), (DS), (RDM) and (MDMAP) were significant for N. Only (RDM) showed significant interaction for the doses of N and S. The dose 420 mg L-1 promoted the highest concentrations in the components leaf and stem. The lowest dose 105 mg L-1, N promoted the highest concentrations of S in the leaf and stem. The assimilation of S by the rosemary plants was dependent on the doses of N.

The field experiment was carried out at Regional Research and Technology Transfer Station (OUAT), Mahisapat of Dhenkanal district during kharif season of 2014 and 2015 to study the “Effect of different sources and doses of Sulphur and Boron application on Yield, nutrient content and nutrient uptake of Groundnut under Mid Central Table Land zone of Odisha”. The experiment was laid out in randomized block design with three replications comprising of seven treatments T1 - Soil Test Based Fertilizer Recommendation (STBFR), T2 - STBFR + Sulphur @ 20kg /ha from Gypsum Source, T3 – STBFR + Sulphur @ 40kg /ha from Gypsum Source, T4 - STBFR + Sulphur @ 20kg /ha from Gypsum Source + spraying of Borax @ 0.3% twice before and after flowering, T5 - STBFR + Sulphur @ 20kg /ha from Bentonite Sulphur Source, T6 - STBFR + Sulphur @ 40kg /ha from Bentonite Sulphur Source, T7 - STBFR + Sulphur @ 20kg /ha from Bentonite Sulphur Source + Spraying of Borax @ 0.3% twice before and after flowering. It was revealed that T7 recorded significantly higher pod yield (17.14 q ha-1), 100 kernel weight (38.93 g) and shelling percent (66.00) followed by T4 with pod yield (15.80 q ha-1), 100 kernel weight (37.60 g) and shelling percent (65.10). T7 was superior over T1 with the yield advantage of 24.2 % and B: C (2.10). The Concentration of nutrient N, P, K, S and B in the harvested pod was also found highest in T7 i.e. 4.34 %, 0.70% , 0.88 %, 0.39% and 17.77 mgkg-1 followed by T4 having concentration of 4.26% ,0.66 % , 0.83 %, 0.35% and 17.23 mgkg-1 respectively. The same treatment T7 also recorded higher uptake of N, P ,K, S and B in pod with 79.47, 9.20 ,19.83,6.23 kg ha-1 and 31.43 g ha-1 respectively.

The Effect of Amending Soil with Waste Elemental Sulfur on the Availability of Selected Macroelements and Heavy Metals

Elemental sulfur of waste origin may be a valuable sulfur source for plants. However, assessing the suitability of environmental use of a waste material should confirm there is no harmful effect of the material on soil environment. The purpose of the incubation experiment was to assess the availability of selected elements (P, K, Ca, Mg, Fe, Mn, Zn, Cu, Cr, Ni, Pb, Cd) in soils supplemented with waste elemental sulfur. The research was conducted on two soils: light and heavy, and with three sulfur doses applied to each soil. Available forms of elements in the soils were extracted 60 days after the waste introduction, with three reagents: 0.01 mol L−1 CaCl2, Mehlich 3 and 1 mol L−1 HCl. Additionally, to determine the impact of the introduced sulfur on soil acidification, soil pH was periodically checked during the experiment. The sulfur addition intensified acidification of the light soil, and, to a lesser extent, of the heavy soil. The acidifying effect was stronger when the sulfur dose was higher. The content of available forms of elements in the soils depended mainly on the strength of the used extractants (generally, the highest amounts were extracted with 1 mol L−1 HCl and the lowest with 0.01 mol L−1 CaCl2). The effect of sulfur introduction on element availability was small. No harmful effect on element availability in soils was stated.

Enxofre, gesso e composto orgânico na produção de couve-de-folha

Fertilizantes sulfatados, gesso e matéria orgânica são fontes contendo enxofre (S) que auxiliam no crescimento e composição química das brássicas. Estudos com S em couve-de-folha (Brassica oleracea L.var. acephala) são raros. O objetivo deste trabalho foi avaliar a utilização de gesso e composto orgânico no plantio, seguido de cobertura de sulfato de amônio, na produção de couve-de-folha. Tratamentos: composto orgânico (30 t ha-1), ou gesso (1,2 t ha-1) individualmente, composto orgânico mais gesso. Enxofre total aplicado a 0; 93,31; 186,69, ou 280 kg ha-1, correspondendo a 0; 465,5; 931 ou 1400 kg ha-1 de sulfato de amônio, e foi dividido em 7 aplicações. O N foi fixado (280 kg ha-1) e complementado com 630, 415,1, 208,6 ou 0 kg ∙ ha-1 de ureia. Aos 30 DAT, foram coletadas as primeiras amostras de folhas, com comprimento mínimo de 20 cm; folhas adicionais foram colhidas a cada 10 dias, em um total de 8 colheitas. Após cada colheita, foram avaliados o comprimento total (incluindo o pecíolo da folha) e o número de folhas por planta, largura e peso fresco. O preparo do solo e a dose de enxofre não influenciaram a produtividade, e ureia ou sulfato de amônio podem ser usados ​​como fonte de N. Nenhum sintoma de deficiência de enxofre ocorreu e as plantas tiveram em média 15,6 t ha-1 de folhas.

Dimethyl Ether (DME) and DME/LPG mixtures resistance characteristics of modified natural rubber compounds

The use of Liquified Petroleum Gas (LPG) in Indonesia is quite high, the volume reaches 6.7 million tons per year. Indonesia currently still imports 70% of its domestic consumption of LPG, or about IDR 40 trillion. Imports of Liquid Petroleum Gas (LPG) continues to increase every year. Dimethyl ether (DME) is one alternative to renewable fuels because its availability in the country is quite abundant. When DME applied as household fuels, some components such as metals and rubber should include resistance to DME, such as stoves, rubber hoses, rubber components in regulators and tube valves. Lemigas has succeeded in developing a DME resistant stove but still not found a rubber that is resistant to DME. This research aims to find a natural rubber formula that is resistant to DME and DME / LPG mixture. The study was conducted by varying the dose of sulphur (0.5, 1.5, and 3.5 phr) using 2 types of elastomer, Natural Rubber (NR) and Nitrile Butadiene Rubber (NBR). Immersion was carried out in DME and 3 variations of the DME/LPG mixture (10/90, 20/80, 30/70). The results showed that the compound formula using natural rubber with a sulphur dose of 1.5 phr has the best resistance to DME and DME/LPG mixtures.

Growth and Production of Samosir Local Shallots (Allium ascalonicum L.) with Various Sulfur Doses

The production of Samosir Local Shallots has been decreasing due to land area reduction and the application of cultivation technologies such as fertilization which have not been applied intensively. Sulfur application is expected to be able to increase the growth and production of Samosir local shallots. This research aim was to determine the growth and production of Samosir Local Shallot (Allium ascalonicum L.) on various doses of sulfur. This research used a non-factorial completely randomized design, namely sulfur dose (S) with four levels of; S0 = No Sulfur, S1 = 6 g / plot, S2 = 12 g / plot, S3 = 18 g / plot, number of replications = 6 replications, number plot = 24 plots. The results showed that the application of sulfur to the growth and production of shallots was higher than without sulfur, application of sulfur at a dose of 0, 6.12, and 18 g / plot was not significantly different from the parameters of plant height, number of leaves, number of tubers, and significantly different from the parameters of tuber fresh weight, and tuber dry weight. The level of sulfur (S) in the shallot at the end of the research ranged from 0.129 to 0.158 mg/kg.

Effect of Graded Levels of Sulphur on Growth and Yield Attributes of Two Sesame (Sesamum indicum) Varieties at Two Different Soil Sulphur Status

Field experiment was conducted at farmer’s field in Coimbatore District of Tamil Nadu with two different soil sulphur status i.e., soil with sufficient and deficient levels of sulphur status in order to study the response of graded doses of sulphur on two different sesamum varieties. The experiment was laid out in split plot design with two factors viz., Two sesamum varieties (TMV 7 - Black var., SVPR 1 - White var.) and Six sulphur levels (0, 20, 30, 40, 50, 60 kg S ha-1). Application of 30 and 50 kg S ha-1 at sulphur sufficient and sulphur deficient soils has increased the plant height at VS and FS, at harvest the highest plant height was recorded. Whereas, other important traits like number of branches per plant, number of capsules per plant, length of capsule and dry matter accumulation has registered the highest response for sulphur application at 30 kg ha-1 which was on par with higher doses in sulphur sufficient soil and in case of deficient soil significant response was observed till 50 kg S ha-1. Among the two varieties, TMV 7 has performed better when compared with SVPR 1.

Boron content in soils under increasing magnesium and sulphur doses in a field experiment

The three-year field experiment (2015–2017) with graded doses of magnesium (Mg) and sulphur (S) was carried out at the Humpolec experimental station (49.5546239N, 15.3485489E; Czech Republic). The interactions between boron (B), Mg and S in the soil were studied. No boron was applied into soils. Contents of B, S and Mg in the soil were determined by the Mehlich 3 and NH<sub>4</sub> acetate methods. The crop rotation was: spring barley-oilseed rape-winter wheat. Three Kieserite doses (S and Mg fertiliser) were applied. Sulphur treatments were 10-20-40 kg S/ha to cereals and 20-40-80 kg S/ha to oilseed rape. The doses of Mg were: 13-26-52 kg Mg/ha to cereals and 26-52-104 kg Mg/ha to oilseed rape. A significant gradual decrease of B-Mehlich 3 was observed under Kieserite treatments during the experiment (from 1.24 mg B/kg in control in the 1<sup>st</sup> year to 0.92 mg B/kg in the 3<sup>rd</sup> year). On the contrary, B-NH<sub>4</sub> acetate contents in soils remained similar during 2015–2017 in control soils (0.33–0.39 mg B/kg) and significantly decreased under Kieserite treatments, namely by 55–57% in 2016 and by 43–48% in 2017. A significant decrease of B content in soils was noted since the second year of experiment after oilseed rape. The boron contents in soils were affected in several ways – by adsorption of B on magnesium oxides and other substances, exchange with SO<sub>4</sub><sup>2–</sup> anions and possible leaching, and also by the uptake by grown crops, mainly oilseed rape.

Production and quality of zucchini seeds after applying sulphur as top dressing and organic compost at planting

The recommendation of fertilization for zucchini (Cucurbita pepo) cultivation is usually made with no differentiation from the other cucurbit crops. Thus, there is a need to examine the doses of fertilizers used for zucchini production, as well as the suitability for cultivars, seasons, and cultivation regions. The aim of this study was to evaluate the influence of sulfur doses at topdressing fertilization and the supply of organic compost at planting on the production and quality of zucchini seeds. A total of eight treatments were studied in a randomized block design with a factorial scheme 4x2, corresponding to four sulfur doses at topdressing (0, 57, 114 and 173 kg ha-1 of S), in the presence (30 t ha-1) and absence of organic compost at planting. The fruits were harvested 62 DAT, and after harvest, the fruits remained in rest for 15 days in order to reach the uniformity of the physiological maturity of the seeds. The production characteristics evaluated were average fresh weight, diameter, dry weight and length of the fruits, fruit yield per plant, weight of a thousand seeds, number and seed weight. Regarding the seed quality, the percentage of germination, germination speed index, first count of the germination test, and electric conductivity, were evaluated. The supply of organic compost at planting had a positive effect on the production and physiological quality of the seeds of zucchini produced. The sulfur applied at topdressing improved the presence of the organic compost and also the production of seeds. Hence, it is recommended to apply 30 t ha-1 of organic compost at planting in association with 57 kg ha-1 of S at topdressing for higher seed yield and quality.

Bioavailability of Sulfur from Waste Obtained during Biogas Desulfurization and the Effect of Sulfur on Soil Acidity and Biological Activity

Sulfur deficiency has been recognized as a limiting factor for crop production in many regions of the world. A 120-day incubation experiment was conducted to assess the effect of the applied waste elemental sulfur on sulfur bioavailability in soil. Four doses of sulfur were applied: 10, 20, 30 and 60 mg S kg−1 dry matter (d.m.) of soil. In order to assess the effect of soil pH adjustment on sulfur oxidation, the research was conducted on two sets of soil samples: one set of soil samples had natural pH, and the second one was limed before sulfur application. Application of waste sulfur slightly affected the soil pH, and increased the content of available sulfur in soil proportionally to sulfur dose. A beneficial effect of waste sulfur application on soil dehydrogenase and catalase activity was found. Liming reduced soil acidity, and significantly increased sulfate content and soil enzymatic activity. Waste elemental sulfur may be an alternative source of sulfur, supplementing the deficiencies of this element in soils. The described way of sulfur waste reuse corresponds with the increasingly common approach to create waste-free technologies in all economy.

Effect of sulphur and FYM on yield content and uptake of nutrient by wheat

A field experiment was conducted at agricultural research farm of R.B.S. college, Bichpuri, Agra during the rabi season of 2018-2019 to study the response of wheat to sulphur and FYM. The plant height enhanced significantly with increasing doses of FYM and sulphur. The grain also increased by supplying higher doses of FYM and sulphur. The soil application of FYM and sulphur improved the contents and uptake values of nitrogen, phosphorus, potassium and sulphur by wheat crop. Better production of wheat crop could be achieved by adopting treatment combination as 40 kg S ha-1 with FYM @10 t ha-1..

Effect of Agronomic Biofortification of Sulphur and Boron on the Growth and Yield of Mustard (Brassica campestris L.) Crop

Background and Objective: Sulphur and boron are found as most critical nutrient elements for the better growth and yield of mustard crop however no such concrete information for their uses in field production of this crop is yet to be reported. Therefore, an experiment was conducted to investigate the effect of agronomic biofortification of sulphur and boron nutrients on the growth and yield of mustard crop.
 Study Design: The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replicates.
 Place of Study: The experiment was carried out in the Crop Botany Field Laboratory, Bangladesh Agricultural University, Mymensingh.
 Methodology: Three doses of sulphur (S) viz. 0, 20 and 40 kg ha-1 and three doses of boron (B) viz. 0, 0.5 and 1.0 kg ha-1 and their possible combinations were used as basal doses. Field data were collected from periodic destructive samplings on the plant height, number of leaves and branches per plant, total dry matter accumulation and finally yield components and yield.
 Results: Sulphur and boron fertilizations significantly influence the plant height, production of branches and leaves per plant, dry matter accumulation and yield attributes and yield of mustard crop. The mustard crop fertilized with 40 kg S ha-1 in combination with 1 B kg ha-1 produced taller plant, higher number of branches and leaves in each plant and higher amount of dry matter per plant while these plant traits were found as minimum when the growing the mustard crops in control plots i.e. the plants received neither sulphur nor boron. Application of sulphur @ 40 kg ha-1 along with boron @ 1 kg ha-1 produced the highest seed yield (2.73 t ha-1) whereas the lowest seed yield (1.08 t ha-1) was found where no sulphur and boron were applied.
 Conclusion: The result conclude that combine application of sulphur and boron @ 40 and 1 kg per hectare, respectively was found to be most effective dose in enhancing growth and yield of mustard crop.
