Phytotoxicity of herbicides on Cynodon dactylon

Field experiment was conducted to manage the sedge and broad leaf weeds in lawn during November to December 2013 to February to March 2014. Experimental plot was red sandy loam soil with pH 6.50.The experimental plot consisted of bermuda grass Cynodon dactylon which was established through turfing. The experimental plot was laid out in a randomized complete block design (RCBD) having 17 treatments with three replications. Herbicide treatments include 2, 4-D sodium salt 80 WP at (2, 3 and 4g/lit of water), 2, 4-D dimethyl amine salt 58% EC at (5, 7.5 and 10 ml/lit of water), carfentrozone ethyl 40 DF at (0.25, 0.5 and 1 g/lit of water), fluroxypyr meptyl 48% EC at (1.5, 3 and 6 ml/lit of water) and chlorimuron methyl + metasulfuron methyl at (0.3, 0.4 and 0.5 g/lit of water). Hand weeding was done at every 20 days interval at 20 days after application of herbicides and also maintained one unweeded control in during November to December and February to March. The phytotoxic symptoms were observed only fluroxypyr meptyl 48% EC applied at 6 ml/lit of water at 3, 7, 10, 15 and 25 days after application of herbicides (DAAH) but it recovered at later stages. However, the other herbicides did not cause any phytotoxic effect on C. dactylon

Effect of pre harvest foliar spray of growth regulators on pre and post harvest parameters in ornamental sunflower genotype M-17R

An experiment was conducted to study the effect of pre harvest foliar application of growth regulators on the pre and post harvest flower quality in ornamental sunflower during the year 2012-13, at College of Horticulture, GKVK campus, UHS, Bagalkot. At 60 DAS highest plant height was with GA3 @ 150 ppm (154.73 cm) followed by GA3 @ 200 ppm (146.20 cm) and GA3 @ 250 ppm (145.53 cm). Sodium silicate @ 250 ppm (4508.77 cm2) registered maximum plant spread at 60 DAS. Foliar application of GA3 @ 150 ppm (25.00) produced highest number of leaves which was at par with Sodium silicate @ 250 ppm, GA3 @ 200 ppm and GA3 @ 250 ppm recording 24.87, 24.80 and 24.67 leaves respectively. Calcium sulphate @ 200 ppm registered highest leaf area of (4930.30 cm2) which was at par with Sodium silicate @ 250 ppm, Calcium sulphate @ 300 ppm, Chlormequat chloride @ 500 ppm, Sodium silicate @ 350 ppm, and Chlormequat chloride @ 1000 ppm with 4792.64, 4735.04, 4721.75, 4503.05 and 4430.02 cm2 respectively

Evaluation of ornamental sunflower for value addition

An experiment was conducted at College of Horticulture, GKVK, campus, Bengaluru, UHS, Bagalkot during 2012-13 to study the suitability of ornamental sunflower for dry flower production. Highest flower weight loss was with corn meal and silica gel (90.75 and 88.45 per cent). Silica gel followed by borax powder took least number of days for drying of flower heads (9.40 and 12.60 days respectively). Colour retention in dried ornamental sunflower was highest with control treatment and silica gel with a score of 4.63 and 4.44. Flower appearance was best with silica gel (4.44) which was at par with control with a score of 3.81. Best texture score of (4.31) was highest with silica gel followed by control (shade), corn meal and alum powder which recorded 3.63, 3.31 and 3.25 respectively. Best flower shape after drying period as with silica gel (4.38).The results reveal silica gel and corn meal as best drying agents in ornamental sunflower

Photoelectron angular distributions in photodetachment from P-

The angular distributions of electrons ejected in laser photodetachment of the P- ion have been studied in the photon energy range of 0.95-3.28 eV using a photoelectron spectrometer designed to accommodate a source consisting of collinearly overlapping photon and negative ion beams. We observe the value of the asymmetry parameter β starting at zero near the threshold, falling to almost -1 about 0.5 eV above the threshold and eventually rising to a positive value. The experimental data has been fitted to a simplified model of the Cooper-Zare formula which yields a qualitative understanding of the quantum interference between the outgoing s and d waves representing the free electron. The present results are also compared with previous results for other elements involving p-electron photodetachment

Standardisation of agro-techniques for flower quality parameters in ornamental sunflower (Helianthus annus L.)

An experiment was carried out on standardisation of agro-techniques for flower quality parameters in ornamental sunflower during 2012-13 at GKVK, campus, College of Horticulture, University of Horticultural Sciences, Bagalkot. In three way interaction effect longest stalk length (36.33) was in the treatment combination of mulching i.e M1 (with mulch) with a spacing of S1 (60 cm x 40 cm) at the fertilizer rate F1 (40:60:40 NPK kg ha-1). Stalk girth was maximum with mulching treatment of M1 (with mulch) at a spacing of S1 (60 cm x 40 cm) with the fertilizer rate of F3 (80:90:80 NPK kg ha-1) and without mulch at the spacing of S1 (60 cm x 40 cm) with fertilizer rate of F3 (80:90:80 NPK kg ha- 1) recording 0.49 and 0.46 cm respectively. Mulching i.e M1 (with mulch) at spacing S1 (60 cm x 40 cm) with fertilizer rate if F3 (80:90:80 NPK kg ha-1) produced plants with largest flower head diameter (13.24 cm). The treatment combinations of M1 (with mulch) + S1 (60 cm x 40 cm) + F3 (80:90:80 NPK kg ha-1) 4.65 cm recorded broadest flower disc diameter. Considering the results ornamental sunflower can be grown best without mulching, at a spacing of 60 x 30 cm or 60 x 40 cm with optimum to higher fertilizer dose to give best flower quality in ornamental sunflower

The Outcomes of Selective Nerve Root Block for Disc Induced Lumbar Radiculopathy

Introduction : Use of Selective Nerve Root Block (SNRB) in lumbar region to relieve radicular pain along the course of a particular nerve is being practiced in the recent past. We observed and tabulated therapeutic outcomes of this procedure in management of radiculopathy induced by a prolapsed disc affecting a particular lumbar nerve root. Methods : 40 patients with various grades of disc prolapse affecting a particular lumbar nerve root presenting with chronic radicular pain were identified irrespective of age and sex. All were injected with a combination of 40 mg of Methylprednisolone based suspension with local anaesthetic over the affected nerve root and results were analyzed. Results : Those graded mild had 4.3 months relief and those graded moderate had 2.5 months relief. Those with severe disc prolapse had no relief except for the immediate postprocedural relief. Only 20% patients had relief up to 6 months. Conclusion : Effect of SNRB is typically short acting in majority of patients and recurrence is expected. It creates a window period with reduced pain but of varied intervals depending on the pathology. It did not alter the prognosis in those with severe disease where surgery is well indicated. Level of Evidence – Level 4

Short-term augmentation of venous drainage with extra-corporeal shunt and simultaneous auto-transfusion, for salvaging a congested free flap

Adequate drainage of venous blood is the most critical part of successful free tissue transfer. We report a case of anterolateral thigh flap used for covering open communited tibial fracture. The flap was salvaged with short term augmentation of venous drainage with external shunt. The drainage was continued for six days. It was confirmed that there is no more congestion after blocking the catheter and then the drainage was discontinued on seventh day. The flap was successfully salvaged. This method has potential applications in multiple situations for successful salvage of free tissue transfer
