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.

Abstract Background Understanding the relationship between dry matter yield production and forage quality throughout the growing season will help to optimize the cutting intervals between harvests in different Alfalfa (Medicago sativa L.) varieties. An experiment was conducted to assess the effects of harvest frequency on forage yield and quality of 2 improved cultivars (ILRI-6984 and var. DzF-552) of alfalfa (Medicago sativa L.) in Western Dembia district over 20 months during 2017 and 2018. Four harvest frequencies (every 30, 40, 50 and 60 days) were compared in a randomized complete block design (RCBD) with 4 replications. The experiment was laid down in a randomized complete block design (RCBD) in factorial arrangement with four replications. To assess their production potential plant height (cm), number of branches per plant, fresh biomass yield (t ha−1) and dry matter yield (t ha−1) of the forge and its nutrient content were recorded. The data collected was subjected to analysis of variance (ANOVA) by using the general linear model (GLM) procedure in Statistical Analysis System (SAS) (2003) version 9.1. Results The results revealed that highest forage dry matter yield was recorded for variety ILRI-6984 harvested every 40 days (26.8 t DM ha−1) and for var. DzF-552 when harvested every 60 days (24.1 t DM ha−1) (P<0.001). While crude protein concentration tended to decline as age at harvest increased, there was little consistency in the pattern. Crude protein yields were also inconsistent across treatments but ILRI-6984 harvested every 40 days produced the highest yields (6.5 t ha−1) (P<0.001). Conclusion These preliminary findings need to be confirmed under field conditions on a large scale along with longer-term studies to examine the longevity of the stands at these harvest frequencies. Irregular harvesting based on stage of maturity should be compared with fixed inter-harvest intervals.

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.

Forage sorghum [Sorghum bicolor L. Moench 'Brown midrib' (BMR)] and annual legumes lablab [Lablab purpureus L. 'Rongai' (L)] and mucuna [Mucuna pruriens L. 'Vine 90 d' (M)] are suitable fodder for the dairy industry in Puerto Rico, but BMR harvested at 90 days, usually has low crude protein (CP, 6%) content, which limits its usefulness. There is the possibility of increasing the CP by intercropping legumes with BMR, but this option has been only slightly investigated. This study proposes to compare BMR in monoculture and in intercropping with 'Rongai' (SL) and 'Vine 90 d' (SM), in addition to L and M in monoculture, in terms of total leaf mass (FM) and botanical components (sorghum, legumes and weeds) and chemical (CP and fiber fractions) at two harvest times. The experimental plots (25 m2) were sown in February and August 2008 in a randomized complete block design with five replications. At each harvest time, 2 m2 MF area was sampled 90 days after sowing. Data were analyzed by using the MIXED procedure of SAS and mean separation tests were performed by using F-protected LSD at 95% level of confidence. No significant differences (combining fodder botanical component and weeds) were detected for the total MF between BMR and BMR associated with legumes in monoculture, with mean values of 8.94, 8.81, and 8.42 Mg/ha for BMR-'Rongai', BMR-'Vine 90 d', and BMR, respectively. Overall, there was no significant difference in MF between May and August (8.1 vs. 7.5 Mg/ha). 'Rongai' yield (Mg/ha) did not change between May and August (3.6 vs. 3.0) but was lower in the intercrop (2.74) than in monoculture (3.94). 'Vine 90 d' had the lowest yield of 2.8 and 1.3 Mg/ ha in May and August, respectively. No differences (P > 0.05) in NDF and ADF content between BMR and BMR-'Rongai'-'Vine 90 d', whose values were 60.1 and 63.9% and 40.1 and 46.5%, respectively. However, differences (P < 0.05) were found in CP content between monoculture and intercropping, with values of 14.1, 11.1, and 6.0% for 'Rongai', 'Vine 90 d', and sole BMR, respectively, whereas the BMR-'Rongai' and BMR- 'Vine 90 d' CP were 9.8 and 9.1%, but these last values exceed by three units the percentage in BMR. In conclusion, BMR intercropped with 'Rongai' and 'Vine 90 d' improved the forage chemistry and helps to control weeds while favoring the performance of desirable botanical components.

This research was conducted to determine performances of seven alfalfa cultivars with different fall dormancy rates in terms of dry matter yield and some quality parameters under Mediterranean conditions throughout the years of 2007-2009. In the study, cultivars were evaluated for dry matter yield (DMY), leaf/stem ratio (LSR), crude protein (CP) content, crude protein yield (CPY), acid detergent fiber (ADF), neutral detergent fiber (NDF), digestible dry matter (DDM) content and relative feed value (RFV). According to average of two year results, there were significant differences among alfalfa cultivars in terms of all characters studied. Mean DMY, LSR, contents of CP, ADF, NDF, DDM and RFV were determined as 18.147 t ha-1, 0.82, 17.4 %, 41.0 %, 49.0 %, 56.9 % and 114. The highest DMY averaged over two years was obtained from cultivar Nimet while lowest one was obtained from Magnum 5. As a dormant cultivar, Magnum 5 was superior in terms of LSR and CP content to the other alfalfa cultivars and it was lower in ADF and NDF content than the others. It was concluded that cultivar Nimet with the highest DMY and CPY yields can be recommended as a non-dormant cultivar for farmers in regions of Turkey with the Mediterranean climate.

Ten Napier grass genotypes (accessions) were assessed across 3 locations, Bako, Boneya Boshe and Gute, for forage dry matter (DM) yield, crude protein (CP) concentration, leaf:stem ratio, nutrient composition and digestibility characteristics during 2016 and 2017. The genotypes were evaluated in a randomized complete block design with 3 replications. Mean DM yield was higher for accession ILRI 16804 across all locations followed by ILRI 16801 and ILRI 16800. Leaf:stem ratio, CP concentration and CP and digestible organic matter (OM) yields also varied significantly among genotypes with the highest values obtained for accession ILRI 16804 across all locations, followed by ILRI 16800 and ILRI 16801. Yields of DM, CP and digestible OM and leaf:stem ratio were higher at Boneya Boshe and Gute than at Bako and higher during 2017 than during 2016. The consistently superior performance of ILRI 16804, ILRI 16801 and ILRI 16800 in both years across the 3 sites suggests that these genotypes should be studied further on farms and in differing environments before being recommended for general cultivation in this area. Examining performance with more frequent harvests and feeding studies with livestock would confirm the benefits to be obtained from planting these new accessions.

The expansion of sugarcane cultivation, especially in areas with low natural soil fertility, such as savannah regions, requires greater efficiency in the application of nutrients, mainly nitrogen (N). The objectives of this study were to evaluate the effects of the application of different sources and doses of nitrogen on the dry matter yield and productivity of sugarcane in the plant cane cycle and the residual effect of such application on the first ratoon cycle of sugarcane (var. SP80-1816) cultivated in a dystrophic Red Oxisol. The experimental design was a randomized complete block design analyzed in a factorial scheme of 2 × 4 with three replications. The evaluated factors consisted of two sources of N (ammonium nitrate (AN) and urea (U)) and four doses of N (0, 60, 120 and 180 kg ha-1). Samples of the aerial part of the sugarcane were collected. The structural components of the aerial part were separated, and the leaf dry matter (LDM), stalk dry matter (SDM) and dry matter of the aerial part (DMAP) were analyzed. The productivity of stalks (PS) was determined by weighing all stalks present in the useful area of each plot. In the plant cane cycle, AN resulted in greater gains in the SDM and PS of sugarcane than did U. In the first ratoon cycle, a residual effect was observed in response to N application, which showed an increase in SDM and PS. Under the conditions of this study, to achieve a higher PS in both cycles, the application of 180 kg N ha-1 is recommended

Feed Costs

Maize forage is poor in protein content which shows its low quality and nutritive value. Regarding to high feed costs of protein supplementations, legumes can be used in livestock nutrition for their high protein content and, thus, providing cost savings. Since legumes have low dry matter yield, acceptable forage yield and quality can obtained from intercropping cereals and legumes compared with their sole crops. In this study, maize (Zea mays L.) and climbing bean (Phaseolus vulgaris L.) were intercropped in different sowing densities and their monocropping equivalents were tested to determine the best intercropping system on forage yield and quality. Maize was cultivated alone (75 000 plants ha-1) and intercropped with bean as follows: 75 000 plants ha-1 of maize and 37 500 plants ha-1 of bean (MB1), 75 000 plants ha-1 of maize and 50 000 plants ha-1 of bean (MB2) and 75 000 plants ha-1 of maize and 75 000 plants ha-1 of bean (MB3), in rows alternating with maize. The highest dry matter yield was produced by MB3 (20.9 t ha-1), and the lowest by maize (16.9 t ha-1). All intercropped systems had higher crude protein contents, MB1 (92 g kg-1 DM), MB2 (99 g kg-1 DM) and MB3 (110 g kg-1 DM), than the maize (77 g kg-1 DM). Intercropping of maize with bean reduced neutral and acid detergent fiber, resulting in increased forage digestibility. Therefore, maize intercropping with bean could substantially increase forage quantity and quality, and decrease requirements for protein supplements as compared with maize.

A study was carried out to determine the response of open pollinated sunflower (Helianthus annuusL. cv. Shumos) to boron fertilizer. Spring and autumn grown plots were sprayed with boron (0, 50, 100, 150, 200, and 250 mg L−1) in a randomized complete block design. The results showed that boron and green Leaf area/LAI measured at the end of seed filling were linearly related in the spring crop. In the autumn crop, the relationship between boron and dry matter yield was linear, and applications above 100 mg L−1significantly increased dry matter compared to the control. For the autumn crop, 100, 200, and 250 mg L−1significantly increased seed number compared to the control, but only the 150 mg L−1treatment increased seed weight significantly. Boron tended to decrease the empty seed percentage, and for the spring crop, this was incremental and linear with applications above 150 mg L−1leading to significant reductions in empty seed percentage. Seed yield increased linearly in the autumn crop in response to boron, and 200 and 250 mg L−1applications gave significant increases in yield compared to the control.

Nutritional Studies

Nutritional studies using rats have shown that the grains of Rongai and Highworth, the current commercial cultivars of lablab bean in Australia, and of CPI41222, a white-seeded accession, have low nutritive value. Diets containing raw beans of the three accessions at levels up to 12% crude protein led to severe weight losses of up to 0.89 g/day compared with weight gains of up to 2.8 g/day with autoclaved soybean meal. Autoclaving for 20 min or boiling the grain improved growth rates only marginally. Increasing the period of autoclaving reduced the feeding value; extraction of the grain with saline solution or treatment with formaldehyde failed to improve it. These results are consistent with previous reports of the presence in lablab beans of a heat-labile phytohaemagglutinin. Blood haemoglobin levels were signifycantly depressed on diets which contained Highworth beans. The proteins of all accessions contained low levels of the sulfur-containing amino acids; a deficiency of methionine was confirmed by feeding trials. The level of histidine in the lablab protein was about 50% higher than in soybean and, in supplementation trials, additions of histidine reduced growth rates. In two feeding trials, there were good correlations (R2=0.85 and 0.92) between weight gains and digestible dry matter intake, indicating that the differences in growth rates were primarily the result of differences in intake. Intakes of digestible dry matter and digestible crude protein and the digestibilities of dry matter and crude protein were all significantly lower with Rongai than with the other two accessions. These differences do not appear to be associated with the quality of the protein as shown by amino acid analyses or by the responses to supplementation with essential amino acids. They also do not appear to be associated with seed coat colour, seed size or crude protein content of the grain.
