Soil Level

Forty-four accessions of herbaceous native legumes from the genera Glycine and Galactia were grown in a glasshouse in a soil-sand-nutrient mixture that contained adequate phosphorus, potassium, calcium, magnesium, sulfur and molybdenum for plant growth. They were grown as individual plants with four replications of each. All plants were cut to soil level on August 18; regrowth was cut on October 7, November 22 and December 30 (harvests 1,2 and 3). The herbage was dried and analysed for nitrogen (g N/kg OM), phosphorus (g P/kg OM) and organic matter digestibility (% OMD). There were significant differences between the accessions for values of dry matter yield (P<0.001), nitrogen content (P<0.01), phosphorus content (P<0.001) and OMD (P<0.05). The mean nitrogen content declined at each harvest (40.6,33.7 and 31.7 g N/kg OM, respectively; P<0.05) and OMD of the herbage at harvest 3 was less than that at 1 and 2 (70.4, 71.1 and 67.6%, respectively; P<0.05). Herbage from harvest 1 had significantly greater P values than that from harvests 2 and 3 (4.7,4.2 and 4.4 g P/kg OM; P< 0.05). Plant yield was correlated with both nitrogen yield (r = 0.98; P<0.001) and phosphorus yield (r = 0.93; P<0.01) but not with OMD. Nitrogen content and digestibility were correlated (r = 0.48; P<0.01) but neither attribute was significantly correlated with phosphorus content. Samples of native herbaceous legumes belonging to the genera Desmodium and Kennedia and of some exotic legumes were collected from a nursery and analysed for N, P and OMD. The N and P values of all these legumes were in the range 31.9-39.2 g N/kg OM and 3.0-4.1 g P/kg OM, and compared favourably with those of the legumes grown in the glasshouse. The OMD of the exotic legumes (range 61.3-85.2%) compared favourably with those of the native legumes grown in the glasshouse but the natives Desmodium spp. and Kennedia spp. (range 26.7-35.4%) were very much lower than the Glycine spp. and Galactia spp.

A factorial combination of three levels of nitrogen and three levels of phosphate fertilizer was imposed on native pasture at Katherine over three years from 1956 to 1959. The pasture was composed largely of Sorghum plumosum and Themeda australis. A marked interaction between fertilizers in total dry matter yield was recorded; significant yield increases were obtained only in the presence of both nutrients. Sorghum showed independent responses to nitrogen and phosphate. Themeda was favoured only by a balanced nutrient supply, and with nitrogen in the absence of applied phosphate or vice versa its yield was reduced. The mean nitrogen content of the pasture increased substantially only when nitrogen was applied without phosphate. Response in total nitrogen yield to applied nitrogen and phosphate was independent ; where both nutrients were applied the response was mainly in dg matter yield with little change in nitrogen content, and when only one nutrient was applied the reverse held. Mean phosphorus content increased with increasing level of applied phosphate and decreasing level of applied nitrogen ; the changes were largely independent between fertilizers. Total phosphorus yield increased with increasing level of applied phosphate but was little affected by the level of applied nitrogen. Recovery of nitrogen fertilizer was extremely low, ranging from 5-6 per cent in the absence of applied phosphate to 8-9 per cent at the highest level of phosphate. The practical and ecological implications of the results are discussed.

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 experiment was conducted at screen house of Centre for Dry land Agriculture, Bayero University Kano, in the year 2016. The objective of the study was to determine the effects of poultry manure and nitrogen rates from battery cage and deep litter systems on dry matter yield, morphological characteristics and forage quality of Columbus grass (Sorghum almum). Sorghum almum seeds were sown in 32 plastic containers (dimensions 26 cm height, 28 cm top width and 20cm base width) perforated at the bottom containing 12 kg mixture of sandy and loamy soil in ratio of 1:3. The treatments consisted of poultry manure from two production systems (Battery cage and Deep litter) and nitrogen rates (50, 60, 70 and 80 kgN/ha) in a 2x4 factorial combined in a completely randomized design. Parameters measured were dry matter yield, number of tillers and stem diameter at the late boot stage of Sorghum almum, in addition, forage quality parameters (CP, ADF NDF, digestible dry matter (DDM) dry matter intake as a percentage of body weight (DMI) and relative feud value (RFV)) were also evaluated. The results revealed no significant (p>0.05) difference between battery cage and deep litter fertilized Sorghum almum but deep litter fertilized Sorghum almum had numerically higher dry matter yield (5062.30 kg/ha) than battery cage (4400.40 kg/ha) Number of tillers and stem diameter were found to be significantly greater (p<0.05) in Deep litter (2.56 and5.70mm respectively) compared to Battery cage (1.13 and 5.08mm respectively. Both dry matter yield and stem diameter of Sorghum almum were significantly (p<0.05) highest at 80 kg N/ha. Crude protein was observed to be significant (P<0.05) in Sorghum almum fertilized with poultry manure from deep liter (11.35%) compared with buttery cage (10.05 %). The CP value was observed to increase with increased nitrogen rate with the highest value recorded at 80 kg N/ha (1.71%). Dry matter intake (us a percentage of body weight) was equally greater (p<0.05) in Sorghum album fertilized with deep litter (2.63%) compared to battery cage (2.49%). The value for NDF was significantly higher in sorghum almum fertilized with battery cage, while that of ADF was greater in deep litter it can be concluded that, Sorghum almum fertilized with manure from deep litter system produced better yield and nutritive value.

The effect of 15 planting dates on various growth characteristics of peas var. Dark Skin Perfection was studied in outdoor pot experiments at Vancouver and Agassiz, B.C. Differences in growth and yield between locations and planting dates were partly accounted for by the mean of maximum temperatures for the growth period.At Agassiz where temperatures exceeded the optimum for most growth characteristics in many of the later plantings, the mean of maximum temperatures was negatively correlated with total dry-matter yield, peas per pod, and pea yield; was positively correlated with branching; and had no effect on pods per plant, double-podded nodes, and tillering. At Vancouver, where temperatures were suboptimum for the early plantings and approached optimum for the later plantings, the mean of maximum temperatures was positively correlated with total dry-matter yield, pods per plant, double-podded nodes, tillering, and pea yield but had no effect on peas per pod or branching. A seasonal mean maximum temperature of 68 to 70°F was considered to be optimum for peas.
