Dry matter (DM) yield, in vitro digestibility (DMD%), and nitrogen (N) concentration were determined for 28 cultivars of millet (Echinochloa utilis), hybrid forage sorghum (Sorghum spp.) and maize (Zea mays), under irrigation at Kyabram, Victoria. These summer fodder crops produced large amounts of digestible dry matter (DDM) under intensive irrigated management in northern Victoria, indicating their potential importance for animal production in irrigated warm temperate regions, where pasture dominates the present land use. Single harvest cultivars produced more DM and DDM than did multiple-cut types but with a lower N concentration and generally lower digestibility. Comparing the highest 3-year mean yields for each species, sweet sorghum cv. Honey drip produced more dry matter (273 t/ha) than did maize cv. XL77 (21.6 t/ha) but yields of DDM were similar (14.4 v. 14.0 t/ha). Both yielded more DM and DDM than grain sorghum cv. Pacific 303 (20.1 t DM/ha and 12.4 t DDM/ha). Maize had higher digestibility (65.0%) than grain sorghum (61.5%) or sweet sorghum (53.0% DMD) and higher N concentration (1.1%) than sweet sorghum (0.9%). All maize cultivars had similar dry matter yields but differed in grain yield. Echinochloa millet cv. Shirohie produced a similar amount of DM (16.3 t/ha) and DDM (10.8 t DM/ha) to sorghum x sudan grass hybrid cv. Sudax (17.1 t DM/ha and 10.7 t DDM/ha). This contrasts with their comparative performance at lower latitudes where sorghum hybrids have the higher yield. There was no difference in mean yield between cultivars of sorghum x sudan grass hybrid. Millet had a higher digestibility (65.9%) and nitrogen concentration (1.9%) than sorghum x sudan hybrids (63.3% DMD, 1.5% N). In this environment, maize and Echinochloa millet had similar DDM yield capacities to sorghum cultivars oftheir equivalent type but superior forage quality.

The objective of this study was to evaluate the fermentation profile and chemical composition of old man saltbush (Atriplex nummularia Lindl.) silage supplemented with cassava (Manihot esculenta Crantz) scraps or grain sorghum (Sorghum bicolor) in the proportion of 10% based on natural matter. The experimental design was completely randomized, in a 3 x 7 factorial arrangement (3 treatments and 7 opening days), with three replications. The treatments consisted of three silages: old man saltbush silage, old man saltbush silage + cassava scrap, and old man saltbush silage + grain sorghum. The experiment was conducted at the EMBRAPA Semiarid Animal Nutrition Laboratory, located in the city of Petrolina-PE. Twenty-one experimental silos were used for each treatment; these silos were opened after 1, 3, 5, 7, 14, 28, and 56 days in ensiling. The pH, ammoniacal nitrogen and total nitrogen ratio, dry matter, crude protein, ether extract, mineral matter, organic matter, neutral detergent fiber, acid detergent fiber, total carbohydrates, non-fibrous carbohydrate, and dry matter in vitro digestibility. The additives grain sorghum and cassava scrap increased the dry matter content and reduced pH values. N-NH3 NT-1 values increased as the fermentation processes progressed, and after 56 fermentation days were close to 11%. Silages were classified as excellent in the fermentation process. The addition of cassava scrap and grain sorghum favors the ensiling process of the old man saltbush, providing improvements in the silage nutritive value. During the storage period, the use of these additives promoted a reduction of total losses, inhibition of alcoholic fermentation, and greater carbohydrates recovery, resulting in silage with a nutritive value similar to that of fresh forage, representing an alternative source of additives.

SummaryUnder conditions of semi-deep water (51–100 cm) rice varieties with greater plant height produced more dry matter and grain yield as N fertilizer was increased from 0 to 20 and 40 kg/ha. The varieties which performed better in a situation of slow rise in water level to a depth of 120 cm could not survive a quick rise in water level owing to their lesser plant height and elongation ability. The loss of dry matter (dead and dried leaves) was also greater in varieties susceptible to deep water than varieties tolerant of deep water.With the increase in N fertilizer, there was increase in plant height, number of tillers, dry-matter production and grain yield. The loss of dry matter was less in crops given N fertilizer than in those not given N fertilizer. The varieties capable of producing higher grain yield in response to N fertilizer under semi-deep water did not improve their grain yield under intermediate deep water (15–50 cm). With increase in application of N fertilizer from 0 to 40 kg/ha the N concentration in grain increased. N concentration did not vary in straw under intermediate deep water, there was no definite trend in semi-deep water, and it was higher under conditions of semi-deep than intermediate deep water.

The nitrogen concentration in dry matter of the fifth leaf during growth of a greenhouse tomato crop was determined. Plants of hybrid Monte Carlo were grown in 4.5 L bags, using a commercial substrate, in a plant density of 3.3 plants m-2. A nutrient solution containing, in mmol L-1: KNO3, 4.0; K2SO4, 0.9; Ca(NO3)2, 3.75; KH2PO4, 1.5; MgSO4, 1.0; iron chelate 19. 10³, was used as reference. Microelements were added by a commercial mixture. The T3 treatment was equal to the reference nutrient solution, whereas in treatments T1, T2, T4 and T5 quantities of all nutrients from T3 were multiplied by 0.25, 0.50, 1.25 and 1.50, respectively. In each treatment, the volume of 1 L of nutrient solution was supplied to each plant once a week by fertigation. Periodically destructive measurements were made from anthesis to ripening of the first truss, to determine dry matter and N concentration in shoot and in fifth leaf tissues, counted from the apex to the bottom of the plant. Five dilution curves were fitted from data of N concentration in the fifth leaf and shoot dry matter accumulation during growth of plants. A general relationship was adjusted between actual N concentration in shoot (Nt) and in the fifth leaf (Nf): Nt = 1.287 Nf (R² = 0.80). This relationship could be used to estimate the N status of plants by means of a nitrogen nutrition index (NNI), from analysis of the fifth leaf sap.

Due to a high stooling coefficient and good growing after cutting, sorghum can be used in the green conveyor in the summer between the cutting of annual and perennial grasses, in the fall when the growth of perennial grasses stops. Hybridization of Sudan grass with CMS-lines of various sorghum types (grain and sweet), produces highly heterotic sorghum-Sudan hybrids which exceed the parental forms in green mass productivity by 1.5 times or more. The identification of new sorghum-Sudan hybrids with high heterotic effects on productivity of green mass and dry matter with their future introduction into production is an important direction of sorghum breeding. The purpose of this work is to identify the main stages of the development of sorghum-Sudanese hybrids and to estimate indicators of their productivity and quality. The CMS lines of grain and sweet sorghum, highly productive varieties of Sudanese grass and new sorghum-Sudan hybrids are the objects of the study. The initial stage is the selection of parental forms. Highly productive and permanent varieties are of great necessity as pollinators. In our studies, these are the varieties “Svetloplenchataya 1”, “Chernoplenchataya 11” and “Chernoplenchataya 10” with 33–42 t/ha of green mass for 2 cuttings. Due to the more powerful plant development the new sorghum-Sudanese hybrids produce 52–77 t/ha of green mass for 2 cuttings. Genuine heterosis is 22.6–102.6%. During the study there have been identified the hybrids “APV-1115 x Svetloplenchataya 1” and “Zersta 38 x Chernoplenchataya 11”, that combine the maximum values of the productivity of green mass and dry matter.

Fermentation Parameters

The cultivation of sorghum for silage production has gained more space each year because of its satisfactory nutritional characteristics, resistance to water deficit and adaptability to various types of soil. Thus, the use of sorghum silage has been an alternative for periods of low forage production, providing quality food for ruminants. In this context, the objective was to evaluate the fermentation parameters and quality of sweet and biomass sorghum silages added with doses of vinasse. The experiment was a 2 x 5 factorial completely randomized design with three replications of two sorghum species (sweet and biomass) and five doses of vinasse applied to the soil: 0; 50; 100; 150 and 200 m3 ha-1, totaling 30 experimental silos. For silage, sorghum species were harvested in the 105-day cycle, with 30.5 and 32.3 g kg-1 dry matter, for biomass and sweet sorghum, respectively. The results showed that the biomass sorghum silage showed higher dry mass production. However, the sweet sorghum silage presented a lower buffering capacity, NH3-N, and higher concentration of lactic acid. Doses of vinasse increased the content of crude protein, in vitro digestibility of dry matter and ether extract and reduced fiber fractions in both sorghum species, showing that both species can be used for silage production. Vinasse is a promising alternative to organic fertilizer, since the use of 200 m3 ha-1 positively influenced the fermentation parameters and nutritional value of the sorghum silages.

Sudan Grass

Fodder oats (Avena sativa L, cv. Cooba) and Sudan grass (Sorghum sudanense cv. Greenleaf) were grown in pots in glasshouses with day/night temperatures of 27/22 and 21/16°C. Plants were harvested at the emergence of each leaf and at various stages after anthesis. Growth rates and changes in dry matter content, nitrogen, cellulose and in vitro digestibility in oats were similar under both temperature regimes, but more primary leaf and less panicle were formed at the high temperatures. Development of Sudan grass was more rapid at the high temperatures, but production of main shoot, panicle and tillers was much less and the nitrogen contents and in vitro digestibilities were consistently lower than at the low temperatures. Sudan grass produced much more dry matter than oats. Differences in composition were in general not large, though stem digestibility remained higher in Sudan grass after anthesis. Tropical species, because of their efficiency of photosynthesis and water use, warrant further study of their nutritive value as forage crops in temperate regions.

An important goal in dairy systems is to increase production while achieving environmental targets associated with lower nitrate leaching from soils. One approach is to identify forages that grow more at a given level of nitrogen (N) input and result in a lower N intake per kilogram dry matter (DM) consumed. However, while N responses have been well described for perennial ryegrasses, less information is available for alternative grasses, legumes and herbs. In the present study, conducted on the Canterbury Plains, New Zealand, six species (perennial ryegrass, Italian ryegrass, white clover, lucerne, chicory and plantain) were grown at six N-fertiliser rates ranging from 0 to 450 kg N/ha.year and managed under irrigation and cutting management. Herbage DM yield and N concentration were measured over 12 months. As N-fertiliser rate increased from 0 to 450 kg N/ha, annual herbage yield increased linearly (from 4794 to 14 329 kg DM/ha.year in grasses and from 7146 to 13 177 kg DM/ha.year in herbs). In contrast, annual herbage yield for legumes was unaffected by N-fertiliser rate and ranged from 11 874 to 13 112 kg DM/ha. Additionally, there were contrasting responses in herbage N concentration between species. At all N-fertiliser rates, herbage N concentration was highest in legumes (43.4 g N/kg DM), then herbs (30.7 g N/kg DM), and lowest in grasses (25.8 g N/kg DM). The N concentration of legume DM was unaffected by increasing N-fertiliser rate, whereas in grasses and herbs it increased. Results suggested that there were no benefits in using herbs instead of grasses for reducing N intake in livestock in an irrigated Canterbury environment.

Important Direction

In the conditions of a high drought of climate of the Nikolaev area and fluctuations of temperature on years the important direction of increase of productivity of arable land is cultivation of drought-resistant cultures and improvement of the technological receptions directed on creation of highly productive agrocenoses. Sorghum is a crop that can withstand high temperatures and prolonged droughts: to consume one kg of dry matter, it consumes almost 1.5 times less water than corn and 2 times less than cereals. Its value is also due to the versatility of use, the ability to give stable yields, the possibility of growing on unproductive soils. This article evaluates the energy efficiency of growing sugar and grain sorghum in the context of climate change.

Pasture Yield

The effects on pasture yield and composition and on sheep performance of paraquat applied during spring to annual pastures were studied in three experiments. One experiment was on clover dominant pasture and the other two were on pure stands of ryegrass. Spraying reduced dry matter at the beginning of summer in only one of the three experiments, In this experiment, spraying at head emergence of the ryegrass caused the greatest yield loss. Dry matter was lost from untreated pasture following anthesis of the grasses as they senesced but sprayed pastures had proportionately the same losses. Spraying at head emergence increased the proportion of grass leaf in the mature dry ryegrass pastures, but later applications were much less effective. The effects of paraquat on nutrient concentrations in the mature herbage varied between experiments. On the clover dominant pasture, N, K, Ca, and Mg were higher in the clover on unsprayed plots but not in the grass component. With pure ryegrass pastures, spraying resulted in significantly higher nitrogen concentration but had little effect on other nutrients. Spraying at head emergence gave a higher yield of nitrogen per hectare of ryegrass but otherwise paraquat tended not to affect or to give slightly reduced nutrient yields. The in vitro digestibility of annual ryegrass decreased rapidly after head emergence. Spraying at this time reduced the rate of this decline, whereas later sprays had little effect on the decline. Paraquat had no effect on losses of nutrients from the pastures that occurred over the summer through weathering. Following paraquat application, the liveweight gain of Merino weaner sheep was improved in one of the three experiments. Higher wool production was recorded in one treatment in one experiment. Paraquat at 0.21 kg ha-' active ion reduced the number of grass seedlings regenerating in the season following spraying.

Cultivation Techniques

Two experiments were done at Katherine, N.T. to compare the effectiveness of minimum cultivation techniques for establishing both bulrush millet and grain sorghum for stock feed in weedy leys of Townsville stylo (Stylosanthes humilis). Measurements were made of crop yield and regeneration and weediness of the swards after cropping. In the first experiment, tyne cultivation ('chisel ploughing') in the dry season was compared with mouldboard ploughing and rotary hoeing in the wet season and with shallow tyne cultivation ('chisel sweeps') in the early wet season. In the second experiment chisel sweeps in the early wet season and chisel ploughing and rotary hoeing in the wet season proper were used. Crops were established in 6-inch drills and 3-feet rows in both experiments. In the first experiment, chisel sweeps gave yields within 14 to 28 per cent of those obtained by mouldboard ploughing or rotary hoeing, and in the second experiment there were no yield differences between cultivation treatments. Climatological data suggest that no difficulty would be encountered in using chisel sweeps at Katherine in at least three years in five. In the first experiment, establishment technique had no effect on crop yield, but in the second seasonal conditions were more favourable and yield in 6-inch drills was higher than in 3-feet rows. Both crop species completely suppressed the ley and in the second experiment, but not the first, Townsville sty10 content in the year following cropping was 23 per cent greater in the cropped compared with the uncropped treatments. Millet produced more dry matter than sorghum (17420 cf. 13120 lb an acre), but the same nitrogen yield (83.4 lb an acre). In millet 1.2 per cent dry matter and 3.2 per cent nitrogen were in the heads, and for sorghum the figures were 24.8 and 53.7. Sorghum appears to have potential as cattle forage.
