Yield And Quality

Sudan grass and pearl millet are major warm season dryland crops, primarily grown for grain production and used as a major source of dietary energy. Both crops are highly water use efficient and belong to the C 4 group of species with high photosynthetic efficiency and dry matter accumulation rates. Both sudan grass and pearl millet have good forage quality, with an adequate crude protein content; that of pearl millet (8.7%) is higher than that of sorghum (6.0%). Therefore, the present investigation was conducted in the Western Delta Region at El-Naubaria, 40 km south of Alexandria, over two successive seasons to evaluate the forage yield and quality of sudan grass and pearl millet. Field experiments were established on calcareous soils, with five fertilization treatments. The results indicate that pearl millet surpassed sudan grass in fresh (6.56 t/ha) and dry yield (2.91 t/ha), which was 8.89% and 5.26% more, respectively, than for sudan grass. As regards the forage quality, pearl millet had good digestibility and was lower in fibre than sudan grass.

A field study was conducted at St-Augustin, Québec, in 1984 and repeated in 1985 to determine the influence of quackgrass on growth, stand counts, yield and quality of alfalfa established with or without oats as a companion crop. Four densities were obtained by treating quackgrass with glyphosate on 100, 50, 25 and 0% of the plot area. The results indicate that without oats, quackgrass reduced the growth of alfalfa. About 60 d after emergence, a density of 119 shoots m−2 reduced the root dry weight of alfalfa seedlings, but there was no effect of quackgrass on the shoot dry weight and the foliar area in 1984. In 1985, an infestation of 161 shoots m−2 reduced the above three parameters. In both years after establishment, alfalfa stands were thicker in quackgrass-free plots. In pure seedings, quackgrass increased forage yield but decreased the quality of the forage during both seeding years. As compared to the quackgrass-free treatment, a density of 275 shoots m−2 increased forage yields at first cutting of 1985, but there was no effect in 1986. Using oats significantly reduced the aerial growth of quackgrass in both seeding years and at first cutting of year after 1985 seeding. Forage quality, as evaluated by NDF concentration, was reduced at infestations of ca. 300 shoots m−2. Higher infestations were necessary to reduce crude protein concentration relative to that of quackgrass-free alfalfa. The ligno-cellulose content (ADF) was not influenced by quackgrass densities. The critical density of quackgrass in alfalfa lies between 150 and 300 shoots m−2. Above this level, quackgrass significantly reduces the quality of the forage.Key words: Quackgrass, alfalfa, critical density, forage yield, forage quality, companion crop

Introduction: In the temperate-semiarid region of Aguascalientes, Mexico, most of the rural population depends on rainfed agriculture related to the family milk production system. Objective: To evaluate the effect of different fertilization practices on forage yield and quality of three rainfed crops in four- and six-row seedbeds. Methodology: Five fertilization treatments were evaluated: T1) control (no fertilization), T2) chemical fertilization (40-40-00 kg·ha-1 of N-P-K), T3) mixture (28-40-00 kg·ha-1 and 26 kg of zeolite), T4) organic fertilizer (5 t·ha-1 of bovine manure) and T5) mycorrhiza (inoculation with 350 g·ha-1 of mycorrhizal substrate). Maize and sunflowers were planted in four rows, and sorghum in six rows. A randomized complete block design with four replicates was used. Results: Dry matter yield in relation to the control, in T2, T3 and T4 was 100, 84 and 26 % for maize, 123, 177 and 67 % for sunflowers, and 52, 49 and 91 % for sorghum, respectively. T5 was higher compared to T1, but without statistical difference. Forage quality of the three crops showed no increase, except for crude protein in T2 and T3. Limitations of the study: Results correspond to a single cycle (spring-summer). Originality: Good agronomic practices for forage production were established. Conclusions: Agronomic practices (minimum tillage, in situ rainwater harvesting, sowing methods and fertilization) generate a positive effect on yield and forage quality in rainfed crops.

Fall applications of pronamide [3,5-dichloro(N-1,1-dimethyl-2-propynyl)benzamide] control or suppress quackgrass [Agropyron repens(L.) Beauv.] in established alfalfa (Medicago sativaL.). Studies were initiated to evaluate benefits of pronamide usage in areas where quackgrass is a problem. Alfalfa swards severely infested with quackgrass were treated with pronamide. Forage quality of first cutting alfalfa was significantly improved with pronamide usage, but second and third cutting forage quality was not greatly affected. First cutting hay from pronamide-treated and untreated areas was fed to goats and dairy cows in feeding trials. Animal intake of total forage dry matter, digestible dry matter, and digestible crude protein was increased with pronamide usage. A reduction in need for supplemental protein, an increase in efficiency in dry matter conversion into milk, and a 20% increase in milk production resulted from controlling quackgrass in alfalfa with pronamide.

Application Date

Clethodim was applied to tall fescue to determine the effects of application timing (fall, early spring, mid-spring), rate (0, 5.6, 11.2, or 22.4 g ai ha−1), and use of crop oil (0 or 2.3 L ha−1) on seedhead density and forage yield and quality of tall fescue. Increasing the rate of clethodim or adding crop oil reduced seedhead density and forage yield, and generally improved forage quality. There was no effect of application date in 1988 and 1990, but seedhead density and forage yield decreased from the November to the March application date in 1989.
