Growth Analysis And Chemical Composition Of Sulla (Hedysarum Coronarium L.), P A. Pinto, G J. Barradas, P C. Tenreiro Aug 2024

Growth Analysis And Chemical Composition Of Sulla (Hedysarum Coronarium L.), P A. Pinto, G J. Barradas, P C. Tenreiro

IGC Proceedings (1993-2023)

Perennial legumes like sulla (Hedysamm coronarium L.), with interesting autumn-winter growth may be important in Mediterranean agriculture. Sulla produces earlier than other forage crops and reduces annual seed and machinery costs. Also, similarly to annual legumes, it can be introduced into crop rotations with benefits on system diversification and fertility improvement. In order to characterise growth and potential yield, a growth analysis was performed during the first growing season of a sulla crop. Chemical composition through the growing season was also determined, allowing quality evolution analysis. These preliminary results led us to conclude that the sulla crop shows a …

Analysis Of Undried, Unground Forage With A Visible-Near-Infrared Monochromator, J S. Shenk Aug 2024

Analysis Of Undried, Unground Forage With A Visible-Near-Infrared Monochromator, J S. Shenk

IGC Proceedings (1993-2023)

Near-infrared (NIR) instruments are now available that will analyse forage (hay, silage and pasture) for crude protein, fibre constituents and some elements without drying or grinding the sample. The accuracy of this new method of sample analysis is not quite as good as the accuracy of NIR analyses of dried and ground samples. However, given the sampling error associated with obtaining a representative forage sample from a load of hay, silo or pasture, this new method of analysis can provide useful information. In addition, instruments scanning the visible and the near-infrared spectrum can quantify forage colour as well as composition. …

Genotypes Of Dry, Mature Subterranean Clover Differ In Shear Energy, S K. Baker, L Klein, E S. De Boer, D B. Purser Aug 2024

Genotypes Of Dry, Mature Subterranean Clover Differ In Shear Energy, S K. Baker, L Klein, E S. De Boer, D B. Purser

IGC Proceedings (1993-2023)

Variation in voluntary feed intake accounts for about half of the variation in feeding value among forages, and shear or comminution energy is a good predictor of constraint to forage intake. We have developed a technique to determine the energies required to compress and shear green or dead feed material. Among 5 genotypes of subterranean clover (Trifolium subterraneum) there is a negative relationship between the energies required to compress and shear them, and the voluntary feed intake of them by sheep. The two genotypes that were most difficult to shear contained more stem and petiole than the other …

Sustainability Of African Farming Systems With Particular Reference To Soil Fertility, Multiple Cropping Systems And Weed Ingress In Smallholder Systems In Humid Tropical Africa, Bede N. Okigbo, Elly N. Sabiti Aug 2024

Sustainability Of African Farming Systems With Particular Reference To Soil Fertility, Multiple Cropping Systems And Weed Ingress In Smallholder Systems In Humid Tropical Africa, Bede N. Okigbo, Elly N. Sabiti

IGC Proceedings (1993-2023)

Africa continues to face a food and agricultural crisis, the effects of which are sometimes exacerbated by drought and civil strife. The food crisis is the result of the inability of African countries in the humid tropical areas and other zones to produce enough food to satisfy escalating demand, owing largely to rapid population growth and pressures of modernisation. Furthermore, the inability of these countries to earn adequate incomes and the lack of food security, especially in some countries suffering from drought, civil strife or war, has resulted in increasing reliance on food aid to fulfil their food import requirements. …

Factors Restricting The Success Of Pasture Establishment In The Mid-Altitude Zone Of Yunnan Province, South-West China, Li Shuan, Gao Zen Yin, Zhao Wen Hong Aug 2024

Factors Restricting The Success Of Pasture Establishment In The Mid-Altitude Zone Of Yunnan Province, South-West China, Li Shuan, Gao Zen Yin, Zhao Wen Hong

IGC Proceedings (1993-2023)

Factors restricting success of pasture establishment were studied at Lunan Milk Goat Breeding Farm (24°51 'N; 1770 m) from 1989-1990. It was found that establishment was adversely affected by moisture stress, hard bare ground, infertile acid soil, storms, seed­harvesting ants, crickets and birds. These factors resulted in physical loss of seed, loss of seed viability, failure of germinated seed to emerge or develop roots and mortality of seedlings, thus causing failure of pasture establishment, Measures to overcome these problems are: appropriate sowing time, good seedbed preparation and sowing technique, recommended fertiliser use and seed treatment with pesticides.

IGC Proceedings (1993-2023)

In recent field studies, bahiagrnss (Paspalum notatum Flugge), a major forage crop in Florida, did not respond lo added Phosphorus fertiliser even though preplant Mehlich I (Ml) soil test indicated very low extractable P (<10 mg/kg). Surface (Ap), E, spodic (Bh) horizons of a Spodosol, limed spodic horizon (BhL), and commercial builders sand were packed into cylindrical plastic bags in selected combinations. The combinations were Ap-B-S, Ap-E-Bh, Ap-E-BhL, and sand. P was applied in 2 rates as O and 60 kg P/ha to selected bags. Bahiagrass sod with its stolon-root system was collected from an unfertilised bahiagrass field, then placed on the soil surface within the growth bags. The experiment was arranged in a completely randomised design with 4 replicates in a glasshouse. Total forage yield, root dry weight, root growth and distribution were determined in each bag over a period of 175 days. Total forage dry matter was increased with addition of 60 kg P/ha in all treatments. Root growth was not influenced by treatments but dry root weight was different in each treatment. Overall forage crude protein content was not influenced by treatments.

Potential Yield And Adaptability Of Tropical Forages In Different Ecological Regions Of Burundi, P Brandelard, O Ncamihgo

IGC Proceedings (1993-2023)

The permanent grasslands based mainly on Eragrostis olivacea are (disappearing in Burundi, because of the increasing density of small . farms. As a result, the integration of forage cultivation in the traditional farming systems becomes of vital importance for the survival of livestock production. A 5-year investigation on yields, nutritive value, persistence and adaptability to soil and altitude of several indigenous and introduced tropical forage grasses and legumes in various ecological regions of Burundi led to proposals that some well-adapted species and cultivars be distributed to farmers. Some species, like Tripsacum andersonii, Pennisetum purpureum and Desmodium intortmn, are quite …
