A 3-year study on the stages of growth of birdsfoot trefoil (Lotus corniculatus L.) at harvest showed that the dry matter yield increased significantly, in the spring growth, with advance in maturity up to the midbloom stage. The highest annual yield was obtained, however, when birdsfoot trefoil was harvested at the full bloom stage both in the spring and summer growth. Maximum protein yield per unit of land was also obtained at the full bloom stage. In the spring forage, the percentages of crude protein, cell content, cell wall, lignocellulose, lignin, cellulose, ash and phosphorus and in the summer forage, the percentages of crude protein, lignocellulose, cellulose, ash and phosphorus decreased significantly with maturity. For all other constituents in both forages, the variations did not reach the level of significance. The accumulation of food reserves in the roots of birdsfoot trefoil in the fall was not influenced by the stages of growth at harvest.Key words: Lotus corniculatus L., growth stage, nutrient reserves, dry matter yield, forage quality, birdsfoot trefoil

A 3-yr study on the stages of growth of timothy (Phleum pratense L.) at harvest showed that the dry matter yields increased, in the spring growth, with advance in maturity. The highest annual yield was obtained, however, when the first cut was taken at the bloom stage. The percentage of crude protein, fat and ash decreased and that of crude fibre increased with the age of the plant. The Ca, P, K, Mg, Na, Zn and Cu contents declined with maturity while the elements Mn, Al, Fe and B did not vary significantly. The food reserves in the lower stem internodes were low at the vegetative stage in the spring (11.7% of DM), but raised rapidly up to the bloom stage (33.9%).

A 3-yr study on height and frequency of cutting showed that alfalfa (Medicago sativa L.) cut at 5 cm from the soil produced significantly more dry matter per hectare than that harvested at 10 cm, but the differences between the two heights decreased with the years and the frequency of cutting. Forages cut at either height had similar mineral composition at any one cutting. However, the percentages of cell walls and of lignocellulose were, in general, highest in alfalfa cut at 5 cm. Height of cutting did not affect the stand nor the accumulation of food reserves in the roots in the fall. The two-cut system gave a uniform production from year to year and maintained the stand at a high level. The three-cut system, the last cut taken in October, yielded the highest yields of dry matter and of crude protein while the four-cut system produced the least and had the thinnest stand at the end of the experiment. Frequency of cutting gave rise to significant variations in the chemical composition of the forages, variations resulting from the difference in the stages of growth at harvest. In general, alfalfa cut at a younger stage exhibited a more valuable composition than that harvested at a later stage. Food storage in the roots varied with frequencies, being highest with the two-cut system and lowest with the four-cut system.Key words: Alfalfa, height and frequency of cutting, yield, chemical composition, food reserves

Phleum Pratense L

An experiment was set up to determine the effect of time and rate of nitrogen fertilization and stage of growth at first cut on yield and digestibility of dry matter and protein content of two timothy (Phleum pratense L.) cultivars, at each of two cuts, No difference in yield or chemical composition was found between cultivars. Highest yields and crude protein contents were measured at rates of nitrogen fertilizer of 112 and 224 kg/ha. Higher yield and protein content were obtained with NH4NO3 applied totally or in split applications in the spring than with urea in the fall. Dry matter digestibility (DDM) was not affected by nitrogen at rates of 56, 112 and 224 kg/ha. First cut was taken at two different stages of growth, and the second cut was taken on the same day in all the plots. At anthesis, yields were higher than at the head stage but DDM and protein content were lower. The opposite was found at the second cut. Except in 1973, total dry matter yield was not affected by the stage of growth at first cut.

Birdsfoot trefoil (Lotus corniculatus L. ’Viking’) was seeded directly into a predominantly orchardgrass (Dactylis glomerata L.) sward following overall or banded applications of paraquat (1,1′-dimethyl-4, 4′-bipyridinium ion, as dichloride salt) or glyphosate [N-(phosphonomethyl)glycine, as isopropylamine salt] to determine the degree of sward control necessary for stand establishment without tillage. Effects of the herbicide treatments and the seeding on botanical composition and dry matter production were determined by a vertical intercept technique and by hand separations of harvests into botanical components. Trefoil establishment was proportional to the degree of sward control during the seeding year. Little trefoil was established by direct seeding without herbicides. The banded herbicide treatments were less effective than overall herbicide applications for trefoil establishment. Trefoil yield obtained following overall application of paraquat was approximately 65% of that obtained following overall glyphosate treatment.Key words: Dactylis glomerata, glyphosate, Lotus corniculatus, herbicide, no-tillage, paraquat

Irrigation trials were conducted in the late dry season (March to June) with Lublab (Lablab purpureus) and Columbus grass (Sorghum almum) in the Sudan savanna of Nigeria. The objective of this study was to determine the dry matter yield (IDM/ha), crude protein (CP), calcium (Ca) and phosphorus(P) in dual-purpose lablab bean and Sorghum almum at 3 irrigation schedules (5, 7 and 10 days irrigation interval). The results obtained showed dry matter yield in lablab increased (P<0.05) and varied from 1.7 to 11.7 IDM/ha. Calcium and P concentrations differed significantly (P<0.05). Mean CP for the lablab was 15.57%. Dry matter yield obtained for Sorghum almum varied (P<0.05) from 11.07 to 19.6 tDM/ha. Concentration of CP and Ca rose and declined thereafter with a mean concentration of 9.86% for CP und 0.08% for Ca while P declined consistently (P<0.05). Intervals of irrigation days had a relationship (P<0.05) with DM/ha, Ca and P in lablab. The increasing trend in foruye yield with increased irrigation interval showed optimum irrigation interval was not attained. It is therefore recommended that longer irrigation intervals be tried to determine the optimum irrigation interval after which forage yield would be depressed due to moisture stress. From the results of the present study Sorghum almum and lablab would be grown successfully at a 10-day irrigation interval.

Abstract This study highlights the effect of drought and ambient temperature on performance and herbage quality of legume monocultures and grass-legume mixtures. In a field experiment, the total dry matter yield, seasonal pattern of dry matter yield distribution, content of crude protein and crude fibre of monocultures of red clover and alfalfa and grass-legume mixtures were investigated during two consecutive dry years (2011-2012). Alfalfa cultivars Kamila and Tereza grown as monocultures or as mixtures with Festulolium braunii (cultivar Achilles) outperformed the red clover cultivars Fresko and Veles and provided a well-balanced total and seasonal dry matter yield during both years. Across all experimental years, crude protein content was significantly higher at alfalfa monocultures and mixture when compared with clover monocultures (P < 0.05). However, considerable lower content of crude fibre at clover monocultures in comparison with alfalfa ones was found. Responses of nutritive parameters of both legume species to weather variables were different. Crude protein content in red clover was independent of rainfall and temperature. In contrast, the crude fibre content correlated with temperature whereby the alfalfa monocultures showed stronger correlations (P < 0.05) than red clover monocultures.

An experiment was conducted to evaluate the effect of growth, biomas yieds and nutritive value of Lablab purpureus, Centrosema pubescens and Mucuna pruriens under rain fed condition in Yola, Adamawa State, Nigeria. The field experiment was laid in a randomized complete block design with the plot divided into three main plots and replicated three times measuring 5x5m with inter and intra row spacings of 0.5m. The five harvesting stages are 6, 8, 10, 12 and 14 weeks, respectively. The growth in height increases with stage of growth and declined with reduction in rainfall. Higher growth were recorded in T3 (3.8 -354.8cm) followed by T2 (2.96-260.20cm) and then T1 (1.50-213.00cm) and the results were presented graphically. The result of the chemical composition of all the legumes showed that the crude protein decreases with stage of growth from weeks 6 -14 (14.40, 12.26, 10.65-10.08, 6.79, 6.49) and ADF and NDF (25.20, 32.15, 27.35-42.13, 40.33, 36.50 and 32.20, 54.45, 47.00- 51.24, 63.53, 66.33), respectively. The biomass yields were significantly different (P<0.05) for all the legumes at different harvesting stages T1 (2744.53-3186.93), T2 (2696.47- 3006.70) and T3 (2843.73-3147.63). It is therefore concluded that legumes could best be harvested between weeks 10 and 12 when the yield and quality are at levels to sustain the animals both for maintenance and production.

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.

The research was carried out in the Eastern Mediterranean Agricultural Research Institute-Hacı Ali location with 4 replications according to the randomized block trial design in 2013-2014. 13 public and 1 private sector maize variety were used as material in the trials. According to the results of the analysis, it was determined that the maize varieties examined showed statistically significant differences in plant properties, dry grass and silage quality. Average plant height, number of leaves, leaf ratio, stem diameter, number of cob, stem ratio, cob ratio and green grass yield were 249.9 cm, 12.97 plant/piece, 19.24%, 22.08 mm, 0.93 plant/unit, 38.40% and 4,251.57 kg/da respectively. According to the analysis, it was observed that the average crude protein content, ADF ratio, NDF ratio, crude ash content, digestible dry matter ratio, crude protein yield, dry matter rate, dry matter yield and hay yield were 8.80%, 34.91%, 59.7%, 7.2%, 61.7%, 993.9 kg/ha, 29.4%, 11,640 kg/ha 12,570 kg/ha in dry grass, respectively. For the silage of varieties, the average crude protein content, ADF ratio, NDF ratio, pH, digestible dry matter rate, dry matter ratio, crude protein yield and Fleig score were 8.22%, 29.27%, 50.48%, 3.57, 66.1%, 28.14%, 926 kg/ha and 118.35, respectively. Burak, Sasa 1 and Ada 334 genotypes performed better in terms of green yield per hectare (53,650, 50,290 and 45,630 kg/ha) and dry matter yield (14,710, 12,810 and 12,410 kg/ha). These varieties can be recommended to producers as silage maize varieties under second crop conditions in Çukurova region of Turkey.

Pure stands of alfalfa, bromegrass, orchardgrass and timothy, each represented by two varieties differing in maturity and/or plant type, were harvested weekly during their first crop growth in 1961, 1962, and 1963.All forages consistently increased in dry matter yield until approximately the early-seed stage. Differences in rate of growth, development and dry matter yield occurred between and within forages and years. Bromegrass, the earliest to start growth, and timothy had similar final yields of dry matter, alfalfa was intermediate and orchardgrass was lowest.At the heading stage in the grasses and at the very-first-flower stage in alfalfa, all species had stored 70% of their dry matter but 82% of their in vitro-digestible dry matter (IVD) yield. Unlike dry matter, IVD yields increased slowly after early June.The crude protein content and yield were considerably lower in the grasses than in alfalfa. Varietal yield differences within a species were small except for orchardgrass. At the suggested harvest time, alfalfa had stored 87% of its maximum crude protein yield, and the grasses, 96%.
