“…The minimum value was recorded in weedy check treatment because weed density was high and more competition between weed and crop for nutrients resulted poor performance of growth attributes. Similar results were found by Singh et al, 2020, they reported that the application of sulfosulfuron + metsulfuron @ 30+2g a.i./ha were found most effective control of the all types of weeds followed by hand weeding control of weeds than the rest of the treatments and improving growth, yield attributes of wheat followed by hand weeding than the rest of the treatments (Singh et al,2020 ). The interactions between nitrogen scheduling and weed management were found non-significant effect on growth attributes of crop during the experimentation.The highest grain yield (q/ha), straw yield (q/ha), biological yield (q/ha) and harvest index (%)(Table -6) was recorded with the nitrogen scheduling N3 -¼ at 4 WAS + ¼ at 6 WAS + ¼ at 8 WAS + ¼ at 10 WAS which was at par with the nitrogen scheduling as N2 -⅓ at 4 WAS + ⅓ at 8 WAS + ⅓ at 10 WAS.…”

Application of sulfosulfuron + metsulfuron (POE) @ 30+2g a.i./ha were found most effective control of the all types of weeds than the rest of the treatments and improving growth and yield of wheat (Singh et al,2020 ). Punia et al, 2018, reported that the higher crop yield and weed control were observed with application of carfentrazone 20 g/ha compared to carfentrazone 10 g/ha.…”

A field experiment was conducted to study response of nitrogen scheduling and weed management on growth and yield attributes of wheat (Triticum aestivum L.) at the Experimental Farm, Mata Gujri College, Shri Fatehgarh Sahib during Rabi season of year 2018-2020. The experiment laid out in Split Plot Design (SPD) with three replications. The nitrogen scheduling includes N1 -½ Basal + ¼ at 4WAS + ¼ at 8 WAS, N2 -⅓ at 4 WAS + ⅓ at 8 WAS + ⅓ at 10 WAS, N3 -¼ at 4 WAS + ¼ at 6 WAS + ¼ at 8 WAS + ¼ at 10 WAS while weed management treatment were W2 -clodinafop @ 60 g/ha, W3 -sulfosulfuron @ 25 g/ha, W4-carfentrazone @ 20g/ha along with weed free and weedy check. The results revealed that the maximum growth and yield attributes were recorded of N3 -¼ at 4 WAS + ¼ at 6 WAS + ¼ at 8 WAS + ¼ at 10 WAS which was at par N2 -⅓ at 4 WAS + ⅓ at 8 WAS + ⅓ at 10 WAS and found significantly superior over N1-½ Basal + ¼ at 4WAS + ¼ at 8 WAS.N3 -¼ at 4 WAS + ¼ at 6 WAS + ¼ at 8 WAS + ¼ at 10 WAS + W3 -sulfosulfuron @ 25 g/ha recorded significantly maximum which was significantly superior over all the treatments.

“…The number of DTM was significantly increased by an average of more than one day with PN spray over the control. A similar increase in DTM with PN spray was also observed in earlier studies in wheat ( Singh et al., 2013 ; Devi et al., 2017 ; Agrawal et al., 2021 ). Therefore, senescence is delayed and the grain filling duration is extended, thus improving key yield-related traits.…”

Grain protein content (GPC) is an important quality trait that effectively modulates end-use quality and nutritional characteristics of wheat flour-based food products. The Gpc-B1 gene is responsible for the higher protein content in wheat grain. In addition to higher GPC, the Gpc-B1 is also generally associated with reduced grain filling period which eventually causes the yield penalty in wheat. The main aim of the present study was to evaluate the effect of foliar application of potassium nitrate (PN) and salicylic acid (SA) on the physiological characteristics of a set of twelve genotypes, including nine isogenic wheat lines carrying the Gpc-B1 gene and three elite wheat varieties with no Gpc-B1 gene, grown at wheat experimental area of the Department of Plant Breeding and Genetics, PAU, Punjab, India. The PN application significantly increased the number of grains per spike (GPS) by 6.42 grains, number of days to maturity (DTM) by 1.03 days, 1000-grain weight (TGW) by 1.97 g and yield per plot (YPP) by 0.2 kg/plot. As a result of PN spray, the flag leaf chlorophyll content was significantly enhanced by 2.35 CCI at anthesis stage and by 1.96 CCI at 10 days after anthesis in all the tested genotypes. Furthermore, the PN application also significantly increased the flag leaf nitrogen content by an average of 0.52% at booting stage and by 0.35% at both anthesis and 10 days after anthesis in all the evaluated genotypes. In addition, the yellow peduncle colour at 30 days after anthesis was also increased by 19.08% while the straw nitrogen content was improved by 0.17% in all the genotypes. The preliminary experiment conducted using SA demonstrated a significant increase in DTM and other yield component traits. The DTM increased by an average of 2.31 days, GPS enhanced by approximately 3.17 grains, TGW improved by 1.13g, and YPP increased by 0.21 kg/plot. The foliar application of PN and SA had no significant effect on GPC itself. The findings of the present study suggests that applications of PN and SA can effectively mitigate the yield penalty associated with Gpc-B1 gene by extending grain filling period in the wheat.

“…7, that SRIR and MRR are higher at sintering temperature of 950°C. The possible reason could be that the MFD was found to have highest effect at 950°C of annealing/sintering temperature [11]. Therefore, the prepared bonded magnetic abrasive powder has potential performance as a new magnetic abrasive powder for fine finishing.…”

The customary edged tool for machining is uneconomical for harder and hard to machine materials and furthermore the level of surface finish accomplished is not that great. As of late, a lot of consideration in mechanical engineering has been centered on finishing tasks. Not many investigations have been accounted for till date on the advancement of substitute magnetic abrasive powder (MAP). In this paper, to improve the finishing performance, the abrasive powder were prepared by mechanical alloying of diamond powder and iron (Fe) powder, compacting these with universal testing machine (UTM) and then sintered at different temperature in a sintering machine in an inert gas (H2) atmosphere. These compacts were crushed and sieved to obtain various sizes of MAP. This abrasive powder were micro-structurally examined. The results indicate that the densification increases and porosity decreases with increasing temperature. Moreover, the prepared bonded MAP has potential performance as a new MAP for fine finishing in Magnetic Abrasive Flow Machining (MAFM) process.
