An experiment was conducted during kharif season 2020 at Instructional Farm, College of Agriculture, Ummedganj, Kota. The experiment comprised twenty-four treatment combinations, having four levels of phosphorus viz., 0, 20, 40 and 60 kg ha-1, three levels of sulphur viz., 15, 30 and 45 kg ha-1 and foliar spray of gibberellic acid viz., no spray and spray of GA3 @ 75 ppm laid out in sub-sub split-plot design with three replications. Results showed that application of 60 kg P2O5 ha-1 had significant effect on plant height, dry matter accumulation plant-1, branches plant-1 at 30, 60 DAS and at harvest, root nodules plant-1 and their dry weight at 45 DAS while root nodules plant-1 and their dry weight at 45 DAS andseed yield (1956 kg ha-1) over application of 40, 20 kg P2O5 ha-1 and control. Significantly higher seed yield (1956 kg ha-1) was recorded under application of 60 kg P2O5 ha-1 over application of 20 kg P2O5 ha-1 and control. However, it was found at par with application of 40 kg P2O5 ha-1. Application of 45 kg sulphur ha-1 had significantly higher plant height (cm) at 60 DAS and at harvest, dry matter accumulation (g plant-1) at 30, 60 and at harvest stages, branches plant-1 at 30, 60 and at harvest stage, number of root nodules and their dry weight (g) and seed yield (1742 kg ha-1) which was found at par with application of 30 kg sulphur ha-1 over 15 kg sulphur ha-1. Application of gibberellic acid @ 75 ppm as foliar spray gave significantly higher plant height (cm) at 60 DAS and at harvest stage, dry matter accumulation (g plant-1) at 60 DAS and at harvest, branches plant-1 at 30, 60 DAS and harvestand seed yield (1770 kg/ha) over control.

River sand is a naturally occurring conventional construction material, which has good frictional properties. Due to a steep rise in the construction activities all over the world, natural sand resources are getting depleted. This has favored / forced the construction industry in general and geotechnical engineering practice in particular to go for M-sands. This necessitates a proper understanding of the frictional characteristics of M – sands. In this technical note, the results from a comparative study of the friction angles of river sand and M-sand with reference to the effect of grain size, grain angularity, dry density and gradation are reported. It is shown that M-sand exhibits higher friction angles than river sand at minimum density levels and river sand exhibits higher friction angles than M-sand at maximum density levels, on average, irrespective of grain size. It is also shown that poorly graded M-sands exhibit higher friction angles than well graded M-sands at minimum density levels, whereas well graded river sands have higher friction angles than poorly graded river sands irrespective of density levels.

Background: Soybean is an important legume as well as oil seed crop grown in a varied range of climate and soils. Phosphorous and sulphur is an important macronutrient required for plants. Their deficiency in soil is a worldwide concern for production of food crops. Therefore, present investigation was done to study influence of phosphorus and sulphur fertilization on productivity, profitability and quality of soybean. Methods: An experiment conducted during kharif 2021 and laid out in factorial randomized block design with three replications having four levels of phosphorous (0, 20, 40 and 60 kg ha-1) and three levels of sulphur (15, 30 and 45 kg ha-1). The data was recorded, analysed and computed statistically. Result: The results indicated that application of 60 kg P2O5 ha-1 and 45 kg S ha-1 gave significantly higher yield, monetary returns and quality of soybean over rest of phosphorous and sulphur levels. However, it was found at par with 40 kg P2O5 ha-1 and 30 kg S ha-1.

An experiment was conducted at Instructional Farm, College of Agriculture, Ummedganj, Kota during kharif, 2021. The twelve treatment combinations comprised of four levels of phosphorus viz., 0, 20, 40 and 60 kg ha-1 allocated in main plots and three levels of sulphur viz., 15, 30 and 45 kg ha-1 in sub plots. Results showed that application of 60 kg P2O5 ha-1 had significant effect on plant height at 60 DAS and at harvest, number of total root nodules plant-1, effective root nodules plant-1 and dry weight of root nodules at 45 DAS, chlorophyll content at 45 DAS and leaf area index at 50 DAS of soybean over application of 20 kg P2O5 ha-1 and control but it was found at par with 40 kg P2O5 ha-1. The maximum seed yield (1942 kg ha-1) and straw (3305 kg ha-1) yield of soybean were recorded under application of 60 kg P2O5 ha-1 over application of 20 kg P2O5 ha-1 and control but it was found at par with 40 kg P2O5 ha-1. Significantly higher plant height at 60 DAS and at harvest, number of total root nodules plant-1, effective root nodules plant-1 and their dry weight at 45 DAS, chlorophyll content at 45 DAS, leaf area index at 50 DAS, seed yield (1870 kg ha-1) and straw yield (3179 kg ha-1) of soybean were recorded under application of 45 kg sulphur ha-1 which was found at par with 30 kg sulphur ha-1  and both these sulphur levels gave significant increase over application of 15 kg sulphur ha-1.
