Effect Of Clipping Frequency Of Some Fodder Grasses In The Semi-Arid Region Of Tamil Nadu, India, K Manoharan, K Paliwal Jun 2024

Effect Of Clipping Frequency Of Some Fodder Grasses In The Semi-Arid Region Of Tamil Nadu, India, K Manoharan, K Paliwal

IGC Proceedings (1993-2023)

Clipping frequency and water stress play a major role in the biomass production of grasses. Bajra - Napier BN2 and CO1 showed maximum above ground biomass under monthly clipping without water stress. The above ground biomass of Bajra-Napier BN2, Panicum maximum Hamil and Guinea grass were not affected under weekly and fortnightly clipping with water stress. Water stress affected the monthly clipped and unclipped plant above ground biomass but the below ground biomass increased in all the fodder grasses except Brachiaria mutica.

Long Term Weed Management Effects In Alfalfa, Randy Dovel, Mylen Bohle

IGC Proceedings (1993-2023)

Five herbicide treatment regimes were applied to spring and fall seeded alfalfa from 1991 to 1995 at two locations, Klamath Falls and Powell Butte, Oregon. Treatments were evaluated by measuring alfalfa crown and weed stand counts, yield, weed content and forage quality of all cuttings each year. Weed control treatment did not affect hay yield at Klamath Falls. Severe weed competition in 1991 caused lower yields in untreated plots in 1992 at Powell Butte. Weed growth was most pronounced in the first cutting at both sites. The presence of weeds did not adversely affect forage quality in any cutting except …

Effects Of Method Of Renovation And Rate Of Nitrogen On Naturalized Pastures In Atlantic Canada, H T. Kunelius, M R. Carter Jun 2024

Effects Of Method Of Renovation And Rate Of Nitrogen On Naturalized Pastures In Atlantic Canada, H T. Kunelius, M R. Carter

IGC Proceedings (1993-2023)

Pastures in Atlantic Canada require periodic rejuvenation to maintain productivity. The effects of method of pasture renovation, soil loosening by paraplowing and nitrogen rates on naturalized pastures were determined. Both direct drilling and cultivation and sowing Lolium perenne L. and Trifolium repens L. in naturalized pastures increased the yields slightly and proportion of white clover. Loosening the soil by paraplowing tended to reduce the yields of naturalized swards. Nitrogen concentration and digestibility of dry matter were greatest in sown pastures.

The Effect Of Phytotoxic Substances In Permanent Grassland, E Haugland, R Elven Jun 2024

The Effect Of Phytotoxic Substances In Permanent Grassland, E Haugland, R Elven

IGC Proceedings (1993-2023)

The concentration of phytotoxic substances in permanent grassland was studied and related to botanical composition in a two year study. Species that were negatively correlated to growth retardation varied between the two years. This may have been caused by variation in growth conditions between the two years, but may also indicate that single plant species are not the main source for the phytotoxic substances. Dead decomposing tissue may instead be the main source of phytotoxic substances in permanent grassland.

Dryland Grazing Evaluation Of Grasslands Gala Grazing Brome, B L. Sutherland Jun 2024

Dryland Grazing Evaluation Of Grasslands Gala Grazing Brome, B L. Sutherland

IGC Proceedings (1993-2023)

Grasslands Gala grazing brome (Bromus stamineus), was evaluated for seasonal production and persistence under dryland conditions. Gala was compared with cultivars from three different Bromus species and a high endophyte ryegrass, under three sheep grazing managements which varied in duration and intensity. Seasonal herbage yields indicated that Gala persisted under all managements, but was more productive under short and medium rotation grazing than long rotation lax grazing. Results of this five year evaluation indicate that Gala compares favourably with existing cultivars, with its broad range of tolerances making it a desirable option as a perennial in temperate dryland pastoral …

Influence Of Fall Cutting Management And N Fertilization On Winter Survival Of Lolium Perenne L., P Nadeau, Y Castongauy, R Michaud, J Surprenant

IGC Proceedings (1993-2023)

Two perennial ryegrass cultivars known to differ in winter hardiness were subjected to six fall managements comprising two N rates and three fall cutting treatments. Water-soluble carbohydrate changes, winter survival and freezing tolerance were measured as well as subsequent spring production. Fall cutting treatments had strong effects on winter survival as cuts taken late in the fall reduced survival to a greater extent than earlier cuts. Nitrogen fertilization had no preponderant effect on the acquisition of cold tolerance at least under the N levels applied in this study, but was related to more vigorous spring growth. The superior winter survival …

Lamb Performance On Russian Wildrye And Russian Wildrye-Legume Mixtures, David W. Koch, Limei Yun Jun 2024

Lamb Performance On Russian Wildrye And Russian Wildrye-Legume Mixtures, David W. Koch, Limei Yun

IGC Proceedings (1993-2023)

Alfalfa, sainfoin and cicer milkvetch provided relatively little increase in forage production, however, they improved forage palatability and quality, increasing total forage consumption. Over years 3 through 5 of the stand, lamb production per hectare was more than doubled with alfalfa and sainfoin, compared with Russian wildrye (RWR) alone. Cicer milkvetch was relatively slow to establish and did not contribute significantly to mixture quality until Year 5. Alfalfa was more competitive to RWR than sainfoin.

Grazing Sheep On Revegetated Saline Pastures: Effects Of Season And Grazing On Morphology And Nutritive Value Of Saltbush, Atiq Ur Rehman, J B. Mackintosh, B E. Warren, D R. Lindsay

IGC Proceedings (1993-2023)

This experiment was designed to determine the thickness of saltbush (Atriplex amnicola) stem grazed by sheep, grazing pressure on saltbush in the presence of understorey and the effect of season on the nutritive value of saltbush. Four 0.9 ha plots of Atriplex amnicola were grazed by a group of 10 Merino wethers each. The results indicated that the maximum diameter of stem selected by sheep under extreme conditions was only 1.5 mm. The number of stems chewed per 0.1m2 quadrat were 0.8, 9.6, 20.1 and 18.0 (P<0.05) after 2, 4, 6 and 8 wk. From January to June the nitrogen content (14 to 30 gkg-1) and DMD (0.65 to 0.72) of saltbush leaves remained high. These results suggest that in the presence of understorey the grazing pressure on saltbush was least and increases when the feed from understorey was exhausted. The nutritional value of saltbush did not deteriorate severely during the summer and autumn period.

Impact Of A Pastoral Fallow On The Morphology And Growth Of White Clover (Trifolium Repens L.) In New Zealand Hill Pasture, Z N. Nie, I Valentine, D J. Barker, A D. Mackay, J Hodgson

IGC Proceedings (1993-2023)

Lifting the content and improving the distribution of perennial legumes such as white clover (Trifolium repens L.) of hill pastures in New Zealand is a major objective of a pasture improvement programme. This paper reports on the ecology of white clover over a 2 year post-fallow period. The fallow was a 7 month period without defoliation over spring-summer-autumn. The stolon length and weight of white clover increased from year 1 (94/95) to year 2 (95/ 96) post-fallowing (P<0.1 and 0.05, respectively), while the average internode length declined (P<0.05). However, the white clover growth rate was not significantly increased in the two measurement years. Fallowing significantly increased grass growth rate (P<0.05) in the two years post-fallowing. The grasses seemed to have an immediate response post-fallowing, while the response of white clover was slower and cumulative.
