Role of Sulphur Containing Heterocycles in Medicinal Chemistry | Chapter 8 | Recent Developments in Science and Technology for Sustainable Future

Numerous applications of heterocyclic chemistry can be found in daily life. In the structure of heterocyclic compounds are heteroatoms such as oxygen, nitrogen, and sulphur. Numerous heterocyclic molecules that contain sulphur as a heteroatom have important physiological characteristics and practical medical uses.
 
Sulphur-containing heterocyclic compounds are considered a significant category due to their broad therapeutic applications like antibacterial, antimalarial, anticancer, antifungal, anti-HIV, and anti-inflammatory. This study focuses on the basic structure, properties, and synthesis of thiirane, thietane, thiophene, thiazole, and benzothiophene compounds and their biological importance.

Effect of Sulphur and Boron on the Growth, Yield and Quality of Hybrid Sunflower | Chapter 9| Research Advances and Challenges in Agricultural Sciences Vol. 4

 India is the largest producer of oilseeds in the world in terms of output. Sulphur deficiency is observed primarily due to high crop yield and therefore higher rate of S removal by crops, and lesser use of S-containing fertilizers. As with Sulphur, Boron (B) is also one of the micronutrients required for normal growth and development of many crops. Sunflower is one of the most sensitive crops to B deficiency. This experimentation was conducted to enhance growth and yield, quality, nutrient uptake, post-harvest soil nutrient status and Sulphur use efficiency of sunflower.

The Field investigations were conducted in two locations viz., at Experimental Farm, Department of Agronomy, Faculty of Agriculture, Annamalai University, Annamalai Nagar, Tamil Nadu during March – June 2013 and at farmers’ field at Ko-Chathiram village, Kurinjipadi block, Cuddalore district, Tamil Nadu during July- October 2013 to study the effect of different levels of sulphur and boron on growth, yield attributes and yield of hybrid sunflower cv. Sunbred. The treatment consisted of Sulphur with five levels (0, 15, 30, 45, 60 kg S ha-1) and three levels of boron (0, 0.5, 1.0 kg B ha-1). Totally fifteen treatments were tested and were laid out in the factorial concept of randomized block design with three replications.

The results revealed that growth, yield attributes and yield, quality, nutrient uptake, post-harvest soil nutrient status and sulphur use efficiency were significantly influenced by various S levels in the B levels. Among the different levels of sulphur tried, application of 60 kg S ha-1 with B @ 1 kg ha-1 significantly recorded maximum growth, yield attributes and yield, quality, nutrient uptake, post-harvest soil nutrient status and sulphur use efficiency of hybrid sunflower while 0 kg S ha-1 with B @ 1 kg ha-1 registered minimum values for growth and yield of sunflower. Boron levels significantly influenced the seed and stalk yield in both crops. Among the treatment combinations tried, 60 kg S ha-1 with B @ 1 kg ha-1 has a spectacular effect on growth and yield attributes, ultimately leading to maximum seed yield (2573.25 and 2673.84 kg ha-1) in both crops. The lowest values of growth and yield attributes and yield were recorded by 0 kg S ha-1 with B @ 1 kg ha-1. The oil content of sunflower seeds was significantly influenced by Sulphur application.

Determining the Effect of Sulphur and Boron on Growth and Yield of Boro Rice in Calcareous Soil of Bangladesh| Chapter 7 | Research Highlights in Agricultural Sciences Vol. 4

 The experiment was administered at the field laboratory of Department of Crop Science and Technology, University of Rajshahi, Rajshahi- 6205, Bangladesh all the while the Rabi season from November 2015 to April 2016 to study the effect of Sulphur (S) and Boron (B) on growth and yield efficiency of Boro edible grain (cv. BRRI dhan-28). The experimental region belongs to High Ganges River Floodplain under Agro-Ecological Zone-11 (AEZ-11). The initial field soil was medium arable, silty clay earth and slightly soluble in texture bearing pH 8.4, 1.25% natural resources, 0.10% total N, 16.2 ppm available P, 12.5 ppm possible S, 0.11 ppm Zn, 0.23 ppm B, 0.57 meq/100g K, 4.30 meq/100g Mg, 15.35 meq/100g Ca. The experiment was constructed accompanying two factors namely., factor A (Sulphur) and determinant B (Boron) with three level of doses of each, that is, S0: outside Sulphur (control), S20: 20 kg S/ha, S30: 30 kg S/ha and B0: without Boron (control), B2: 2 kg B/ha, B3: 3 kg B/ha. The experiment was transported in a Randomized Complete Block Design (RCBD) with three replications. In case of Sulphur, the situation S20 (20 kg S/ha) obtained the maximum plant crest (97.811 cm) at harvest, maximum number of tillers hill-1 (26.184) at harvest, maximal panicle distance (24.98 cm), maximum grains panicle-1 (167.37), maximum 1000-grain pressure (27.57g), maximum grain yield (5.46 t/ha) and hay yield (5.71 t/ha), maximum biological yield (11.17 t/ha) and HI (48.88%). Whereas, maximum suffused grains panicle-1 (147.37) and minimum unfilled grains panicle-1 (17.89) were in the direction of S30 (30 kg S/ha). In case of Boron, the highest plant climax (96.378 cm) was about B3 (3 kg B/ha). Highest number of total tiller hilltop-1 (25.149), longest panicle (24.17cm), topmost total grains panicle-1 (165.78), filled grains panicle-1 (144.04) and minimum vacant grains panicle-1 (21.74), maximum 1000-grain burden (25.24g), highest seed, hay and biological yield (4.84, 5.43 and 10.27 t/ha, individually) and highest HI (47.13%) were about B2 (2 kg B/ha).The treatment of S20B2 (20 kg S/ha accompanying 2 kg B/ha) performed best choice response than added situations. So, it can be submitted that S at 20 kg/ha and B at 2 kg/ha with urged dose of NPK and Zn is acceptable for maximum yield of Boro rice in calcareous soils of AEZ-11.
