“…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.

“…Late wheat planting tends to reduce the number of germinations and tillers unit -1 area due to a significant rise in temperature during the crop's tillering period, thus reducing production [4]. Higher seed rate is important for increasing wheat production potential because it compensates the poor tillering caused by the cold temperatures [5].…”

An experiment was conducted at Shradhay Bhagwati Singh Agriculture Research Farm (Hajipur), Chandra Bhanu Gupta krishi Snatakottar Mahavidyalaya, B.K.T., Lucknow (Uttar Pradesh) during the rabi season of 2021-22. The experiment consisted of 12 treatment combinations comprised of 3 seed rates and 4 weed management practices, tested in factorial randomize block design with three replications. The results indicated that different seed rates and weed management practices significantly influenced the growth, yield and nutrient uptake of wheat. The soil of experimental site was silty loam soils having medium organic carbon (0.70%) and nitrogen (270 kg ha-1), phosphorus (27 kg ha-1) and potassium (262 kg ha-1). Crop sown with seed rate, S3 (120 kg ha-1) recorded highest plant height, number of tillers m-2, leaf area index, dry matter accumulation, number of effective tillers, grain yield, straw yield, biological yield and nutrient uptake. However, higher number of grains spike-1, grain weight spike-1, length of spike and test weight was recorded with crop sown with 100 kg ha-1 seed rate. Weed free upto 60 DAS (W1) resulted in significantly higher growth and yield attributes and yields over rest of the weed control treatment. Post emergence spray of Clodinafop + Metsulfuron (60 + 4) g ha-1 recorded significantly higher values of all growth, yield attributes and yield over sulfosulfuron @ 25g a.i ha-1. Weed free upto 60 DAS had highest weed control efficiency followed by Clodinafop + Metsulfuron 60 + 4 g ha-1 (49.78%). However, the highest weed index was noticed in weedy check and lowest with herbicide mixture. The highest net returns (Rs. 69036) and B:C (1.73) were obtained with combination of 120 kg seed rate ha-1 + Clodinafop+ Metsulfuron @ 60g ha-1 +4g ha-1 (PoE) at 30-35 DAS.
