Gibberellic Acid Biosynthesis

Seed yields of ryegrass and tall fescue have increased rapidly over the last seven years; the best farm yields are now reaching 3000 kg/ha, up from 2000 kg/ha. These increases are largely due to the adoption of technologies developed from research funded from grower crop levies and effective technology transfer programmes. The key technologies are (1) the adoption of trinexapac ethyl (TE), a plant growth regulator that blocks gibberellic acid biosynthesis and reduces lodging; and (2) new generation triazole and strobilurin fungicides that give improved disease control and extend the period that green leaf area is maintained on crops. Seed yield data from 10 ryegrass and 6 tall fescue trials with TE, and from 13 fungicide trials are presented. The average seed yield increase in tall fescue treated with 200 g TE/ha and ryegrass with 400 g TE/ha was 67% and 50% respectively. In fungicide trials, seed yields in forage perennial ryegrass were increased by 20% and in turf ryegrass by 42%. A survey of growers indicated 95% of ryegrass growers and 100% of tall fescue growers had adopted the use of TE three years after the commercial release of the product.

Field experiments were conducted in the Department of Seed Science and Technology, University of Agricultural Sciences, Dharwad, Karnataka during 2016-17. The field experiment consisted of 18 treatment combinations involving two seasons viz., kharif 2016 and rabi 2016-17 and plant growth regulators viz., G1: Control, G2 : GA3 @ 50 ppm, G3 : NAA @ 40 ppm, G4 : Cycocel @ 100 ppm, G5 : Mepiquat chloride @ 50 ppm, G6 : Nitrobenzene @ 200 ppm, G7: TIBA @ 50 ppm, G8 : Brassinosteroids @ 200 ppm, G9 : GA3 @ 5 ppm + IAA @ 5 ppm and experiment was laid out in Factorial RBD with three replications. The more number of pods per plant (117.19), number of seeds per pod (4.25), dry pod yield per plant (118.53 g), dry pod yield per plot (2.07 kg), seed yield per plant (114.48 g), pod length (5.66 cm), seed yield per plot (2.32 kg), seed yield per hectare (1,281 kg) was recorded in rabi season than kharif. Among the plant growth regulators more number of pods per plant (120.44), number of seeds per pod (4.44), dry pod yield per plant (120.17 g), dry pod yield per plot (2.21 kg), seed yield per plant (117.60 g), seed yield per plot (2.55 kg), seed yield per hectare (1,360 kg) and pod length (6.04 cm) was recorded in NAA @ 40 ppm, followed by nitrobenzene @ 200 ppm, (119.78, 4.35, 119.54, 2.11, 116.76, 2.42, 1,299 kg and 5.93 cm, respectively). The interaction effect was found to be non-significant for majority of the characters studied. However, foliar spray of NAA @ 40 ppm during rabi season recorded higher crop growth, seed yield and quality parameters as compared to control.

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.

Seed Crops

Plant growth regulators (PGRs) are used as a management tool to minimize plant height and subsequent stem lodging in grass seed crops. Their efficacy is influenced not only by the method of application, but also by the management and genetic variations within and between species. This aim of the study was to evaluate the effect of PGRs on morphological traits of generative tillers and seed yield of Festuca rubra L ssp. rubra (strong creeping red fescue) and F. r. L ssp. commutata (Chewings red fescue) under low and medium doses of spring nitrogen fertilization (40 and 70 kg N ha−1). PGRs were applied as: chlormequat chloride (CCC) at BBCH 30–31; CCC at BBCH 30–31 + ethephon (ET) at BBCH 37–39; CCC at BBCH 30–31 + trinexapac-ethyl (TE) at BBCH 37–39. All the application methods of PGRs resulted in the shortening of the second internode, and the sequential application of CCC with ET or TE also resulted in the shortening of the third internode. In each PGR treatment, the lodging index in the plant (canopy height to tiller length ratio) was higher than that of the control. PGRs had a beneficial effect on the seed yield. The greatest increase in the seed yield was recorded after the application of CCC+TE. No interaction between PGRs and spring N fertilization rates on the seed yield of red fescue. The increase in the dose of spring nitrogen fertilizer from 40 to 70 kg N ha−1 resulted in a significant increase in yield. Seed yield of chewing red fescue cv. Dorosa was 29% higher than strong creeping red fescue cv. Nista, mainly due to an increase in the number of generative tillers.
