The tolerance of mangrove species to salinity should be taken into consideration in the selection of planting sites and suitable species for mangrove ecosystem rehabilitation.

     summary: The data obtained for TFM value of soap with respect to Taguchi design without and with replicates (three replicates) are given in Table 4 and Table 5 respectively. As block design indicates that C and D variables at higher levels are significantly contributed for the increase of TFM value, this can be used to validate Taguchi design, because Taguchi design is also showing similar results.

     summary: The prevalence and distribution of cowpea insect pests may however be influenced by some factors. Recent study suggested that the use of effluent water to irrigate crops may increase incidence, abundance and damage caused by cowpea insect pests possibly reducing cowpea plant productivity and vigor (Tiroesele et al. 2017).

     summary: 3.1 Model validation Since Cox proportional hazard model fits under several assumptions it is better to check whether the fitted Cox model adequately explains the data. Testing the proportional hazards assumption To check the Proportion Hazard assumption of Cox model, we use the scaled Schoenfeld residuals of the final fitted model.

     summary: Morphological divergence has been reported in estuarine fish populations that are not completely geographically separated, suggesting that partial isolation may play a role in population subdivision (Roby et al., 1991, Suneetha & Naevdal, 2001). The differentiable variation in morphology among fish populations has been suggested as indicative of the presence of stock structuring and restricted movement among geographically isolated populations (Uiblein, 1995; Roby et al., 1991; Palumbi, 1994; Jerry & Cairns, 1998).

Seed bacterization with B. subtilis CA32 and T. harzianum RU01 significantly protected bean seedlings from F. solani f. sp. phaseoli compared to the untreated control plants.

     summary: There after treatment 5 showed significantly lower plant height than did other four treatments indicating there is no significant effect on plant height by replacing Albert solution with Gliricidia leaf extract. The five different nutrient solutions tested in this experiment were as follows, T1 -Albert solution 100% (Control) T2 -Albert solution 75 % + Gliricidia leaf extract 25 % T3 -Albert solution 50 % + Gliricidia leaf extract 50 % T4 -Albert solution 25 % + Gliricidia leaf extract 75 % T5 -Gliricidia leaf extract 100 % Treatment combinations were laid in a CRD with four replicates.

     summary: Specifically, the study sought to describe the socio-economic characteristics of the farmers in the study area, identify the types of farm wastes generated on the farms, examine the methods of farm waste management on the farms in the study area, determine the utilization of the farm wastes generated, identify the constraints militating against farm waste utilization in the study area and identify the determinants of farm waste utilization in the study area. The major constraints militating against farm waste utilization includes inadequate access to extension services, inadequate awareness of benefits of farm waste, inadequate facilities for processing of farm wastes to other products and low knowledge on usage of farm waste.
