The commercial importance of linseed (Linum usitatissimum L.) has attracted Agronomist to increase its seed yield using various agronomical and breeding approaches. Plant growth regulators (PGRs) have a significant role in enhancing yield and its related traits in linseed. Hence, to find out effect of different growth regulators on growth, yield attributes, yield and economics of linseed, the present experiment was conducted under AICRP on Linseed, College of Agriculture, Nagpur. Growth regulator shows significant effect on growth, yield attributes and yield of linseed. Plant height and number of capsules per plant was observed highest and significantly superior after application of 400 ppm Gibberellic acid (GA) and application of 0.1 % Tebuconazole which was at par with T7 i.e. 1.0 ppm Auxin + 200 ppm GA and T5 i.e. 75 ppm salicylic acid. Number of branches and number of capsules per plant were also observed at par in the treatment T3 i.e. 200 ppm GA. The seed yield of linseed was recorded significantly higher in T4 i.e. 400 ppm GA which was at par with T7 i.e. 1.0 ppm Auxin + 200 ppm GA and treatment T3 i.e. 200 ppm GA and treatment T5 i.e. 75 ppm salicylic acid. The gross monetary return was found maximum in the treatment T4 i.e. 400 ppm GA, this might be due the maximum seed yield after application of 400 ppm GA, but net monetary return and B:C ratio resulted minimum due to the high market cost of GA (Rs. 9000/- for 400 ppm). Net monetary return and B:C ratio was found maximum in treatment T5 i.e. 75 ppm salicylic acid, this might be due to the low cost of Salicylic acid.

A field experiment was conducted at Dry land Agricultural Research Station, Rangreth, Srinagar, SKUAST-K in Kharif 2020 to study the effect of Plant Growth Regulators and micronutrients on growth, yield and quality of sorghum. The objective of the study was to assess the effect of Plant Growth Regulators and micronutrients on herbage yield and quality. The treatments included; T1: Tricontanol 10 ppm at 30 DAS (foliar spray), T2: Salicylic acid 100 ppm at 30 DAS (foliar spray), T3: 5 kg Zn/ha soil application, T4: 2 kg B/ha soil application, T5: 5 kg Zn + 2 kg B/ha soil application, T6: 5 kg Zn/ha (soil application ) + Triacontanol 10 ppm at 30 DAS (foliar spray), T7: 5 kg Zn/ha (soil application) + salicylic acid 100 ppm at 30 DAS (foliar spray), T8: 2 kg B/ha (soil application) + Triacontanol 10 ppm at 30 DAS (foliar spray), T9: 2 kg B/ha (soil application )+ salicylic acid 100 ppm at 30 DAS (foliar spray), T10: 5 kg Zn + 2 kg B/ha (soil application) + Triacontanol 10 ppm at 30 DAS (foliar spray), T11: 5 kg Zn + 2 kg B/ha (soil application) + salicylic acid 100 ppm at 30 DAS (foliar spray) and T12: Water spray at the time of PGR application. Zn and B were applied at the time of sowing in the soil. The crop was raised with recommended package of practices. In treatments, where zinc was not a treatment, an amount of sulphur through gypsum equivalent to sulphate supplied with 5 kg ZnSO4 was applied to compensate. The crop was sown in 30.0 cm apart lines. The trial was laid out in Randomized Block Design with three replications. The results indicated that all the treatments improved the green fodder yield over control. Among different treatments, T10: 5 kg Zn + 2 kg B/ha soil application + Triacontanol 10 ppm at 30 DAS foliar spray and T11: 5 kg Zn + 2 kg B/ha soil application + salicylic acid 100 ppm at 30 DAS foliar spray produced maximum GFY (493.6 and 490.5q/ha) on locational mean basis. It was significantly superior to other treatments. These treatments improved the green fodder yields by 35.0 % and 34.2 %, respectively, over control (spray of water). In terms of dry matter, similar trend was noted and the improvement with T10 and T11 was to the tune of 36.8 % and 41.0 % over control. Tricontanol 10 ppm at 30 DAS (foliar spray) (T1) improved the green fodder yield and dry fodder yield by 13.6% and 14.3 % respectively over T12Water spray at the time of Plant Growth Regulator application. Similarly spray of T2: Salicylic acid 100 ppm at 30 DAS (foliar spray) improved the green fodder yield and dry fodder yield by 14.4% and 15.4% respectively over T12Water spray at the time of Plant Growth Regulator application. Similar trend was observed with respect to quality parameters (crude protein content and crude protein yield) of sorghum.

To study the effects of salt stress and plant growth regulators (kinetin, gibberellic acid, potassium) on growth, yield, glycine betaine content, phosphoenolpyruvate carboxylase (PEPC) and ribulose biphosphate carboxylase (RBC) gene expression of two Libyan bread wheat varieties, a factorial design of greenhouse experiment with three replications was conducted. Results revealed that salt stress significantly reduced plant growth and productivity of both varieties. Moreover, the addition of kinetin + potassium and gibberellic acid + potassium had improved the performance of the morpho-metric parameters of both genotypes under salt stress; but the performance was more effective for kinetin treatment than for gibberellic acid. At the biochemical level, the results showed that salt stress increased glycine betaine contents in both varieties with different proportions. This increase is more elevated in the presence of kinetin + potassium than the treatment with gibberellic acid+ potassium, which showed an almost similar result as in only salt stress. At the molecular level, the effects of salt stress and plant growth regulators on the PEPC and RBC gene expression showed that the increase was significantly higher for kinetin, gibberellic acid, and salt stress when compared to the control.
