The improvement of brush-covered rangeland seeded to tame forage species following the application of three herbicide mixtures, with and without fertilizer, was documented. The area was located 193 km northeast of Regina, Saskatchewan, on a Waitville loam in the Grey (Podzol) soil association. The highest forage yields were reported on areas that received either a combination of 2,4-D + 2,4,5-T, 2,4-D + dicamba or 2,4-D + picloram and a yearly fertilizer treatment. The forage yields on the three previously mentioned treatments ranged from 109 to 139 g/m2 and from 394 to 424 g/m2 during the first and second years, respectively, of the experiment, respectively.

Forage Yields

A mixture of timothy, orchard grass, red clover, alfalfa and Ladino clover was seeded on areas of upland and dikeland soil at Nappan, N.S. Over a 3-year period plots were cut at 3-, 4- and 8-week intervals to stubble heights of [Formula: see text] and 3 inches. Comparisons were made of forage yields and species contribution under the various cutting intensities on the two soils. Forage yield was 20 per cent greater on dikeland and seasonal distribution of forage was better on dikeland than the upland area with which it was compared. Similar responses between treatments were obtained on both dikeland and upland. Timothy contribution fluctuated widely between high spring values and low fall values while orchard grass regularly contributed about 40 per cent of the forage material. Alfalfa contributed reasonably well initially, but failed to persist under more intense clipping, particularly on dikeland. Ladino clover increased in relative value during the 3 years, performing better on upland under more intense clipping.

Oversowing Lotus uliginosus cv. 'Grasslands Maku' offers considerable scope for improvement of understorey forage production in New Zealand's plantation forests. In a grazing trial in Kaingaroa Forest annual forage yields of predominantly Maku lotus were 3000-5000 kg/ha dry matter (DM) from tree age 4-7 years but declined to 1000-3000 kg DM/ha by age 11 years. Forage yields available for grazing under different tree stockings (100,200 and400 stems/ha) were (up to treeage 11) approximately the same, in spiteof the percentage area covered with slash being significantly affected by tree stocking. Forage species composition since time of oversowing has changed from initial stands of almost pure lotus to a mixture of lotus and lower fertility grasses, particularly Yorkshire fog, and flat weeds. By tree age 11 years (8 years after oversowing) lotus comprises 20-30% of understorey ground cover, both with and without cattle grazing.

Forage Yields

Effects of companion crops, oats, barley, and wheat on light and soil moisture available to the undersown forage species, alfalfa, birdsfoot trefoil, timothy, and bromegrass, are reported. Early in the growing season, barley intercepted the highest percentage of both visible light and light energy, whereas at the end of the season, weeds growing where forage seedlings had been established without a companion crop intercepted a greater amount of light than companion crops undersown with a forage crop. Seedlings growing under companion crops managed as simulated pasture received the greatest amount of light. Soil moisture percentages were higher where forage seedlings were established without a companion crop. Forage yields reflected a greater advantage from improved moisture during establishment than from light penetration.

The Impact

The New Zealand dairy industry recognises that to remain competitive it must continue to invest in research and development. Outcomes from research have ensured year-round provision of low-cost feed from pasture while improving productivity. Some of these advances, discussed in this paper, include the use of white clover in pasture, understanding the impacts of grass endophyte, improved dairy cow nutrition, the use of alternative forage species and nitrogen fertiliser to improve productivity, demonstration of the impact of days-in-milk on profitability, and the use of feed budgeting and appropriate pasture management.

Participatory on-farm evaluation of improved forage crops was conducted in six mixed farming system districts of Southern Ethiopia with the objective to identify farmers preferred forage crops (legumes and grasses). Two annual forage legumes (Vigna unguiculata L. (cow pea) and Lablab purpureus (L.), two perennial legumes (Medicago sativa (L.) (alfalfa) and Desmodium intortum (Mill.) Urb. (green-leaf)), and three perennial grasses (Chloris gayana Knuth (Rhodes grass) and two Pennisetum purpureum Schumach (elephant grass) accessions (No.16800 and 16798)) were evaluated in the study. The major farmers’ criteria considered in the evaluation of forage species were vegetative growth, herbage yield, tillering, protection of soil erosion, palatability, perfor- mance under dry weather conditions, performance in marginal area under low input management, multipurpose use (conservation and soil fertility) and fast growing condition. The study showed that elephant grass accession No. 16798, 16800 and Chloris gayana adapted well and farmers preferred them for their higher herbage yield, vegetative growth, tillering ability and drought resistance. Even though the annual forage legumes Lablab purpureus and Vigna unguiculata were superior in their forage yield, the farmers preferred the perennial forage legumes (Desmodium intortum and Medicago sativa) mainly for their performance under dry weather condi- tion due to their longer growth period. Therefore, the consideration of farmers’ preference for forage crops is crucial for increased adoption of improved forage crops in the region.

The study aimed to evaluate the efficiency of nutrient use in three cactus forage (CF) cultivars (Opuntia stricta and Nopalea cochenillifera), 365 days after planting under different types of fertilizer in two research sites (Condado and Riachão) of the semi-arid region of Paraiba state, Brazil. The experimental design was a randomized block design with treatments in a factorial scheme (3×4), three cultivars of CF (Orelha de elefante Mexicana; Miúda; Bahiana), and four fertilizer treatment (Control; Manure; Manure with Nitrogen; Mineral fertilization) with four replications. The CF cultivars did not differ significantly in nutrient use. That means of physiological efficiency by CF cultivars were 1.62, and 2.36 kg of biomass per kg of nutrient applied in Condado and Riachão, respectively. The efficiency of nutrient recovery was 16% for the Condado, according the following order: K> P> Ca> N> C = Mg and 12% for Riachão: K> P> N> C = Ca = Mg. In the two research sites, the treatment with mineral fertilization significantly increased the efficiency use of N, P and K in comparison to the other treatments. The average for efficiency of nutrient utilization was 25% and 19% for Condado and Riachão, respectively, in the following order for Condado: K> P> N> Ca = Mg> C, and Riachão: K> P> N> C> Mg = Ca. In a CF production system aiming to obtain a yearly harvest cycle, it is necessary to replenish of K and P to maintain the nutritional balance between the soil and CF plant.
