Fodder Production

Small grain cereals such as oats or wheat, when grown on fallowed land, provided fodder yields as high as or higher than those obtained from perennial forage containing alfalfa. However, on a land base comparison, yields of perennial crops were about double those of cereal grains. A 3-yr rotation using annuals in a crop–crop–fallow sequence improved the yield relationship over a crop–fallow rotation only marginally in this semiarid region. Yields of corn or sunflower row crops in rotations with fallow, or with cereals and fallow, were highly variable. Crude protein yields of the perennial forage crops on a given land base were about threefold those from annual crops.

The influence of the improved drainage broadbed and furrow (BBF), as opposed to the traditional flat seedbed over the growing season on the dry matter yield and nutritive value of Avena sativa, Vigna unguiculata, Lablab purpureus, Vida dasycarpa, Trifolium steudneri and Sesbania sesban were studied on Vertisol. Up to 7 t/ha dry matter yield was recorded for Avena sativa and Lablab purpureus when planted on Vertisols with improved drainage. Dry matter yield of forage crops also increased with advance in stage of maturity or subsequent harvests. On both improved and traditional flat seedbed methods, the chemical analysis of forage crops showed similar declines in crude protein content and in vitro dry matter digestibility (IVDMD) levels as the maturity of forage crops progressed.

A study was conducted with Altai wild rye (Elymus angustus Trin.), Russian wild rye (Elymus junceus), crested wheatgrass (Agropyron cristatum), and intermediate wheatgrass (Agropyron intermedium) on their relative merits as forage crops in the arid climate of Saskatchewan. The data show that Altai wild rye produced as much forage as Russian wild rye but less than crested wheatgrass and intermediate wheatgrass. However, it appeared to be less competitive with alfalfa than the other grasses in the test. The nutritive value of Altai wild rye was as good as or better than that of the other grasses; it excelled all of them in crude protein content throughout the season and contained about the same amount of fibre and fat at most stages of development; its ash content was higher than that of the other three grasses in 1954, a wet year, but only higher than the two wheatgrasses in 1957, a very dry year. Comparisons regarding palatability and digestibility suggest that Altai wild rye equals the better grasses in this respect. The study also indicates that nutritive value of grasses throughout the growing season varies much more in wet years when normal plant development occurs, than in dry years when growth is slow and sporadic.

SUMMARYWhite clover (Trifolium repens L.) is well adapted to the cool moist climate of Atlantic Canada, where it improves digestibility and protein content in pastures, but little is known about its role in pasture stockpiled for autumn grazing in this region. The objectives of this study were to determine the effect of autumn harvest dates on dry matter yield and clover content in herbage mixtures. Two experiments conducted in Nova Scotia between 1985 and 1991 on two different soil types showed that the effects of autumn harvest dates were inconsistent from year to year. Herbage growth rates ranged from 11 to 41 kg/ha per day between early September and mid-October. Clover content was generally lower in August–early September than in November harvests and declined in subsequent years irrespective of harvest date or forage species. Kersey White and Sonja white clovers were the highest yielding cultivars. Crude protein declined in late autumn harvests whereas acid detergent fibre tended to increase, and there were differences between years. Forage quality was significantly better in tall fescue (Festuca arundinacea Schreb.) than orchardgrass (Dactylis glomerata L.)/white clover mixtures.

The articles offers the results of studies on the effect of sowing methods, seeding rates and backgrounds supply on yield and economic efficiency of broad bean cultivation for seeds. Increase seeding rate of 0.4 to 0.8 million units per hectare, regardless of sowing methods, increased the content of crude protein at 2.5-3.3 %. Similar changes occurred in the sugar content of the grain. In contrast, with increasing seeding rate, in wide-space sowing and calculated doses of fertilizers usage, resulted in a decrease of crude fiber, fat and ash. Adding the calculated doses of mineral fertilizers at planting in wide-space sowing with a rowing space of 45 cm and seeding rate of 0.6 million units per hectare provides about 10 thousand rubles per hectare, and the profitability level was 78 percent. Formation of high yields of green mass (41.0 tons per hectare) and grain ( 2.34 tons per hectare) of broad bean noted, when adding calculated doses of mineral fertilizers at wide-space sowing method with a seeding rate of 0.6 million units per hectare. I this way, we can see the high net income ( 9742.8 rubles per hectare), the level of profitability (78.0 %) and the cost of 1 ton of grain (5336.4 rubles per ton). The calculations of economic efficiency of fodder beans cultivation for grain showed that a high profitability obtained by making calculated doses of fertilizers, with a rowing method of sowing and seed rate of 0.7 million units per hectare was 59.4 %, while in wide-space sowing (45 and 60 cm) with a seeding rate of 0.6 million units per hectare was 78.0%.

Sole crops and intercrops of field beans (Vicia faba L.) and wheat (Triticum aestivum L.), at three nitrogen rates, were evaluated for production of whole crop forage in two field experiments, one spring and one autumn drilled, on Imperial College at Wye farm, UK, during 1997–1998. Forage quality attributes measured were crude protein (CP), neutral detergent fibre (NDF), acid detergent fibre (ADF), water-soluble carbohydrate (WSC) and ash content. In both experiments, dry matter (DM) and percentage dry matter (DM%) were improved by intercropping compared with beans sole crops. Intercropping enhanced CP and NDF contents and WSC compared with beans and wheat sole crops, respectively. Nitrogen (N) applications up to 75 kg/ha produced the optimal intercrop forage yield and crude protein content. This input of N is smaller than that for other forage crops.

Diets containing Altai wild ryegrass (Elymus angustus Trin.), alfalfa (Medicago media Pers.), or mixtures of these two forage crops were fed to 30-kg growing lambs in digestion stalls, with digestibilities of organic matter (OMD), crude protein (CPD), crude fibre (CFD) and energy (ED) determined following two total fecal collection periods of 8 days each. The same ratios of Altai wild rye:alfalfa were then fed in diets containing 20% barley. The protein content and the digestibility of protein was much higher in alfalfa than in Altai wild ryegrass, while the crude fibre fraction of Altai wild ryegrass was more digestible than that of alfalfa. Addition of 20% barley increased DCP and reduced DCF contents of the diets. Mixtures of the forage crops alone or with barley supplied DCP requirements of the growing lamb. DE contents of the two forage crops were similar and deficient for optimum performance of the growing lamb, although inclusion of 20% barley appeared to correct this deficiency according to chemical composition of the diets. Intakes of all diets fed were insufficient to allow optimum lamb performance, even though chemical analyses suggested that diets containing barley were adequate in DE content.

Relevance and methods. The article presents the results of studies conducted at the Yakutsk Research Institute of Agriculture. Scientific research on the study of promising new forage crops was carried out on site 30 "A" (on the basis of the forage production laboratory of the YANIISKh) on the second floodplain terrace of the river. Lena in 2016–2018. The effect of three sowing dates on the yield of promising annual fodder crops is studied.Results. The results of studies on the growth, development, productivity, nutritional value of promising annual crops are presented. Productivity in three sowing periods during the harvesting period of sunflower reached feed units 1.2– 2.7 t/ha, crude protein — 2.5–5.1 t/ha, corn — feed units 0.7–2.2 t/ha, crude protein — 2.8–6.9 t /ha, oilseed radish feed units 1.1–1.3 t/ha, crude protein 3.3–5.0 t/ha. The optimal sowing and harvesting dates of promising annual fodder crops for the production of high-quality succulent and voluminous feeds are established — 1 term (sowing — I decade of June, harvesting — II decade of August); 2 term (sowing — the 2nd decade of June, harvesting — the 3rd decade of August) in the phase of mass flowering and discarding panicles of the tested feed crops.

Yield And Quality

The changing climate, water scarcity, reduction in the land area under forage crops, expanding ruminant population, burgeoning demands for milk and meat production and food security concerns all insist on a necessary increase in forage production and quality. Cereal–legume mixed intercropping offers a biologically superior option to boost herbage yield and quality of preserved fodder (hay and silage), provided that rationalization of the component crop’s proportional ratio is performed. Therefore, the current study was conducted to determine the forage yield and quality of barley (Hordeum vulgare L.) and pea (Pisum sativum L.) mixtures at the ratios 100:0, 75:25, 50:50, 25:75 and 0:100. The experiment was laid out in the regular arrangement of a randomized complete block design with three replicates. The results exhibited that forage quality was significantly affected by the mixture ratio. There was a significant improvement in protein, fiber rate and digestibility from the mixture. The ratios of barley and pea with 50:50 and 25:75 produced the maximum productivity and the best quality of forage. Regarding forage preservation, silage recorded higher contents of crude protein, ash and lower fiber contents than hay. Among seed mixtures, 0:100 ratio of barley–pea yielded the highest quality of silage with the maximum crude protein, ash and digestibility with lowest fiber contents.
