Effect of sources and doses of Sulphur and Boron application on Yield, nutrient content and nutrient uptake of Groundnut (Arachis hypogea L.)

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.

Role of the Sulphur Source in the Solvothermal Synthesis of Ag-CdS Photocatalysts: Effects on the Structure and Photoactivity for Hydrogen Production

The aim of this work is to study the influence of the sulphur source (elemental sulphur, thiourea and L-cysteine) in the solvothermal synthesis of Ag-CdS over its growth, structuration and state of Ag and how these changes influence on its photoactivity. The differences in the generation rate of the S2− from the sulphur sources during the solvothermal synthesis determine the nucleation and growth pathways of CdS affecting to the silver state and its incorporation into the CdS lattice. The hydrogen production on Ag-CdS photocatalysts decreases according the sequence: thiourea > elemental sulphur >> L-cysteine. The changes in the photoactivity of Ag-CdS samples are analysed in terms of the differences in the insertion of Ag+ into the CdS lattice, the formation of composites between CdS and Ag2S and the formation of CdS crystalline domains with strong confinement effect derived from the different sulphur source used in the solvothermal synthesis.

Regioselective benzannulation of allylic sulfur ylides with ynones: a rapid access to substituted thioanisoles

A novel benzannulation of allyl sulfer ylide (ASY) with alkynones is accomplished for highly regioselective formation of multi substituted thioanisoles where ASY was rarely found to be a 3C component as well as a sulphur source.
