  Field experiments were conducted at the Teaching and research farm, Delta State University, Asaba Campus, Asaba between 2003 and 2005, to determine the effect of organic fertilizer (poultry droppings) on yield of species of forage crop and in their mixtures. The pastures who sown in plots measuring 5x5m in a split randomized complete block design with four replicates and soil fertilized at a rate of 0.5 t ha-1 and without soil fertility. The pastures were first harvested at 8 week after planting and a regular interval of 4 weeks there after. The result of the study showed that, the yield of sole crops and yield of 2 or more forage crop associations with organic fertilizer application was significantly higher (p<0.05) than with fertilizer applications. Also, the aggregates yield of 2 or more crop association was significantly higher (p<0.05) than their component sole crops in the same plot. The grain legume crop association produced diversify of pastures and higher yield both in quantity and quality. It was concluded that organic fertilizer is a possible replacement for organic fertilizer and a mixture of four forage crops association is recommended than sole or 2 or 3 crop association.

  The seasonality of Dacryodes edulis limits the availability of propagules. To forestall its extinction, the effects of different temperature regimes on 3 seed sizes of fruit were evaluated to assess the recoverability of seeds in terms of percentage germination and seedling growth. The percentage germination was 97 for fruit softened at 25 and 50 while 87C for fruits softened at 0C and 85% for fruits softened at 75C and least were 35 for fruits softened at 100C. Plant height was significantly tallest (p<0.05) at 25.8 cm for fruits softened at 50C, plant girth was largest at 4.0 cm for fruits softened at 0, 25, 50 and 75C and number of leaves and leaf area were 8.1 and 63 cm3 for fruits softened at 75C. The seedlings large fruit performed better medium and small. The growth parameters of fruit softened at 100C were most significantly depressed. It is therefore concluded, that different temperature regimes had effect on different percentage germination and on some growth parameters of the plant. However, it is recommended that fruits of Dacryodes edulis whose seeds are intended for planting should be softened at water temperature of between 50 to 75C.

  The fruits of Dacryodes edulis are seasonal and the duration of fruit softening and sensory evaluation is unknown. The effect of different temperature regimes on 3 sizes of fruits were evaluated to asses the duration of fruit softening and sensory evaluation. The duration of fruit softened at 50, 75 and 100C were 1.50.5 to 13.50.5 min were significantly the same (p = 0.05) and significantly different (p<0.05) from fruit softened at 0 and 25C which took 900100 to 145050 min to soften. The sensory evaluation was significantly best for fruits softened at 75C, followed by 50C. The large fruits performed better than medium and small fruits. The different temperature regimes had effect on duration of fruit softening and sensory evaluation. However, it is recommended that, fruits of Dacryodes edulis, which are intended for eating, should be softened at water temperature regimes of 50 to 75C.

  Field experiments were conducted during the April 2004 and December 2005 cropping seasons at Kwale, Ndokwa West local Government Council farm annex, in south western Nigeria, to determine the compatibility of maize, cowpea and egusi-melon as well as their economic yield and the stability of these mixtures. The growth parameters considered were plant height and leaf number of maize, cowpea height and number of branches, egusi-melon vine coverage, weed biomass as well as economic yield while land equivalent ratios were calculated from the economic yield. The result of the experiment showed that sole egusi-melon and in association with maize and cowpea significantly suppressed weeds compared to other cropping systems. The economic yields of sole crops were significantly higher than in their respective crop associations. Associations of three crops had higher combined yields than two crops or sole crops. The LER, was highest in three crop association of 1.91. It was concluded that a system, with the highest combined economic yield, highest LER, in addition to ensuring better crop diversity in the humid tropical environment, a mixture of maize/cowpea/egusi-melon is recommended than sole crops or one or two crop associations.

  One of the main obstacles to the successful utilization of compost in agriculture is the lack of reliable quality criteria and understanding the transformation of organic matter, which take place throughout the whole process. Proper evaluation of composts maturity essential for establishment of such criteria. Because of the diversity of origin of composts. It is impossible to use a single method to evaluate compost maturity. It is best done by a combination of methods. A good index of compost maturity should have an overall trend describable by a monotonic function. Methods for evaluating composts maturity can be categorized into (1) chemical analysis (C/N, CEC and nitrification) (2) physical analysis (odour and temperature) (3) spectroscopic analysis (FTIR and 13C-NMR) (4) plant bioassay (germination and plant growth) (5) chromatographic analysis (sephadex fractionation) (6) degree of humification (HI, DH and HR) (7) microbial analysis (respiration). These tests vary in precision, simplicity, costs, duration and approach. Plant bioassays are considered the most direct test for compost maturity since it shows the effect of compost maturity on plant growth and other maturity tests are correlated with plant growth performance. Spectroscopic methods, sephadex fractionation and degree of humification give an insight to the feasibility of starting material to be transformed, the level of humification and the quality of the humic fraction and the efficiency of a given composting process.

  There is a need to harness fadama lands in Niger-delta as a result of dearth of fertile arable land due to soil infertility from little or no fallow period. This study was carried out, to determine the compatibility of okra, pumpkin and maize in a fadama soil. Oba super2 variety of maize, NHae 47-4 variety of okra and locally sourced pumpkin were sown in October, 2003 and repeated in October 2004, in a randomized complete block design with 4 replicates. Maize and okra were monitored weekly for 8 and 10 weeks respectively for plant height and number of leaves while pumpkin were accessed for % vine coverage. Observation were carried for weed biomass, economic yield, aggregate yield and land equivalent ratio were calculated from the economic yield. The result of the 2 year study showed, that growth parameters did not all follow a consistend trend, although sole crops performed better than in their crop associations. The presence of pumpkin significantly reduced weeds growth in the crop associations. The economic or relative economic yield was significantly higher (p<0.05) in sole crops than in the individual crops of the association, but the aggregate yield was higher in the crop association than in their sole crops plot. The land equivalent ratio was highest in 3 crop association (1.97) than 2 crop association and least in sole crops of 1.00.
