Keeping in view, the deficiency of detailed information on adoption of heat tolerant potato (Solanum tuberosum) variety ‘Kufri Surya’ in Terai Agro-Climatic situation of West Bengal, the field experiment was conducted at the Instructional farm of Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, West Bengal during the rabi season of 2016 to study the effect on heat tolerant variety (Kufri Surya) with different nitrogen levels. Experiment was laid out in a Split-plot design taking two varieties ‘Kufri Jyoti’ and ‘Kufri Surya’ as main plot with six different levels of nitrogen of 0 kg N ha-1, 50 kg N ha-1, 100 kg N ha-1, 150 kg N ha-1, 200 kg N ha-1 and 250 kg N ha-1 as subplot. Results of the experiment showed that the higher values of the growth attributes like dry matter accumulation, leaf area index, in all the sampling dates of experimentation was recorded with 100 kg N ha-1. Owing to the higher leaf area index and dry matter accumulation in shoot, tuber yield was recorded highest from the treatment having 100 kg N ha-1 (28.46 t ha-1).

The study was conducted to know the marketing efficiency of milk and milk products of co-operative and non-cooperative sectors in Prakasam district of Andhra Pradesh. Primary& secondary data was collected from the 4 marketing channels (cooperative society i.e. Ongole dairy, non-cooperative dairies - traditional, private and milk collection centers). It has been found that the price spread of milk was highest in case of channel 3 and minimum price spread was found in channel 4. Highest marketing efficiency of milk was observed in case of channel 4 and channel 6 was the most efficient channel for curd. In the case of buttermilk highest marketing efficiency and the lowest price spread was observed in non-cooperative channel 4. Marketing efficiency of ghee was more in case of channel 1 followed by channel 3 and 2. Findings of the study showed that marketing efficiency of the cooperative dairy plant has been observed relatively less than private dairy plants and marketing efficiency of private channels were found to be more than cooperative channel but the traditional channel was more efficient than the private channel. From the findings of the study, the following implications were drawn. The monthly payment should be made regular and price given to dairy farmers should be increased by cooperative society so that the dairy farmers preferring to this channel will be increased more than at present. The dairy plants should lower the sales commission is paid to commission agents, wholesalers, retailers and other selling agents to reduce distribution cost.

In an effort to address the problem of ineffective power project delivery and poor electricity supply in the south eastern part of Nigeria especially, studies on implications of socio-economic characteristics of the construction skilled labour on effective delivery of electricity in the power sector have reported that remuneration factor among others is very critical for improved electricity power project (EPP) delivery. To confirm the finding, this study therefore investigates the salary and wage rates of the construction professionals and the skilled labour in the government establishments and private firms respectively. Using activity sampling technique, the masonry (block laying) and carpentry trades in the power sector of the south east were investigated. Findings have shown that the average non productive and active times of the trades respectively are at an average ranges of 25% - 37.20% and 62.5% - 75% for the masonry trade; and average of 18.80% - 31.20% and 68.80% - 81.20% for carpentry trade respectively. The study also proves that standard times and standard outputs of the trades respectively stand at 1.37 hr/m2 and 0.75 m2/hr for the masonry trade; and 0.85 hr/m2 and 1.19 m2/hr for carpentry trade respectively. Consequently, the labour rates of the masonry and carpentry trades are estimated at 6 m2 and 9.52 m2 respectively. In an effort to compare the labour rate of the skilled workers in the EPP with those in some major private construction firms and civil service, it was discovered that labour rates of workers in EPP are lesser than the others; likewise the wage rates respectively. Although the labour rate of the skilled labour in EPP are lesser than those in the other places of work, the wage rates of the work trades in EPP are far lesser than the wage rates in the other areas of employment; hence the ratio of the wage rate to labor rates in EPP are significantly lesser than the ratios in the other areas especially, the construction firms in the study area. This study recommends therefore an establishment of a data base framework in the power sector for improved remuneration of the skilled labour that incorporates need based and certified training programme, towards effective delivery of EPP in the south east and Nigeria in general.

Provision of adequate power has been a long time problem in Nigeria. It has negatively affected the socio-economic condition of the society. In an effort to address this deplorable situation, the power sector has been transformed by various political administrations from one form to another over time yet, electricity supply and delivery of Electricity Power Project (EPP) have not been effective. The study therefore seeks to improve on power supply services by way of assessing the implications of the major socio-economic characteristics of the construction skilled labor on effective delivery of EPP in the south eastern states of Nigeria. Field survey method of data collection targeted on the skilled labor of the power sector and the active electricity consumers in the study area was adopted, on a mutually exclusive order. An inferential statistical approach of polynomial regression analyses was used to establish model relationships existing between the skilled labor determinants (age of experience, availability, educational qualification, remuneration and training/retraining) as the independent variables and the different functions of effective EPP delivery (steady supply of electricity, fair charges on electricity consumption, and swift response to complaints and faults) as the dependent factors respectively. Findings show that the significant predictive (independent) variables remaining in the three final models tested for adequacy have positive influences on the models; with remuneration and training determinants common and strongest in their effects on the models. Age of experience and availability of the labor determinants however are in addition contained only in the model for fair charges on electricity consumption, and model for swift response to complaints and faults respectively. It is therefore recommended to all stakeholders in the power sector to align efforts with the power authority in engaging workers on need based training programmes regularly, as well as review upwards and appropriately the workers remunerations so as to boost generally the human capacity industrial base knowledge, motive and comfort; towards effective delivery of EPP in the study area.

Dumpsite waste picking is prevalent in many developing countries of which Kenya is one. Waste pickers play an important role in waste recycling by recovering and providing materials to the waste recycling industry.

Aim: The purpose of the study was to characterise the demographic and socio-economic factors of waste pickers in Nakuru and Thika municipal dumpsites.

Study Design: The research design was a cross-sectional social survey and the sample size was 167.

Place and Duration of Study: The study was carried out in the largest dumpsite in Nakuru and Thika towns found in Nakuru and Kiambu counties respectively.

Methodology:  The data was collected by use of structured questionnaire. The data was analysed using the Statistical Package for Social Sciences. Analysis was by frequency tables, χ2 test and t-test at 95% level of confidence.

Results: The results show that there was parity by gender in Nakuru but in Thika the proportion of females was much higher than that of males. There was significant association between age and site of operation with waste pickers in Thika being on average younger than in Nakuru (χ = 12.605, d.f. = 3, p = 0.006).  Waste pickers in Thika had on average attained a higher level of education than in Nakuru (χ2 = 12.352, d.f. = 3, p = 0.006). Most of the waste pickers (96%) only picked from exclusively from the dumpsite. Waste pickers in Thika spent an average of 10.26±0.23 hours daily in waste picking which was significantly higher (t=-3.709, n=160, p<.001) than at Nakuru (8.97±0.27 hours). The mean number of years of waste picking in Thika was significantly less than in Nakuru (t=4.627, d.f.=158, p<.001).

Conclusion: In conclusion, waste pickers play an important role in waste recycling, with waste picking supporting hundreds of waste pickers in the study area, who are important in integrated waste management and need to be understood, appreciated and supported.

This study investigated the effects of different watering regimes on the growth of Crescentia cujete. The seedlings were subjected to six different watering regimes which include: W1 – control   (watering everyday), W2 – watering once every two days, W3 – watering once every three days, W4 – watering once every four days, W5 – watering once every five days and W6 – watering once every six days; each treatment replicated six times. The experiment was arranged in a Completely Randomized Design (CRD). The study was carried out at the Central Nursery of Forestry Research Institute of Nigeria, Ibadan. Growth parameters assessed include: plant height (cm), collar diameter (mm), leaf production and the biomass accumulation which was sectioned into leaf, stem and the root. The data collected were subjected to one-way Analysis of Variance (ANOVA) and means separation was done using Duncan Multiple Range Test (DMRT) at 5% level of probability. The results showed that there were significant differences among the treatments in plant height and number of leaves produced while there was no significant difference in the collar diameter. However, seedlings watered once every 5 days (W5) performed best in height (20.48 cm) and leaf production (18.42). It was revealed that there were significant differences in the leaf and stem dry weights among the treatments with W5 having the highest weight while there were no significant differences in the root dry weight. Crescentia cujete optimized water shortage for its growth.

Indigenous tree species like Terminalia ivorensis has multiple uses; from timber products to medicinal condiments for treating different ailments. This species is self-incompatible. Thus, habitat protection is a key to its survival and sustenance. This study evaluated the effect of provenance variations on the growth and development of T. ivorensis. Three provenances of T. ivorensis were selected; FRIN Arboretum, Onigambari Forest Reserve and J1 Forest Reserve. Thirty (30) seedlings of T. ivorensis were selected and marked at each provenance for assessment of growth parameters for a period of twelve weeks. The growth parameters included: seedling height, collar diameter, leaf count and leaf area. Also, soil samples were collected from each provenance to test for nutrient composition. Results showed that J1 Forest Reserve had best performance across the growth parameters assessed with 10.4 cm plant height, 2.02 mm collar diameter, 11 leaves count and 20.5 cm2 leaf area respectively. This growth parameter result differs significantly from the other two provenances. This was also attributed to the nutrient offered by J1 Forest Reserve with 1.18% and 2.20% of organic carbon and organic matter in the soil respectively. Also, the available phosphorus which is involved in photosynthesis, respiration, energy storage and transfer, cell division and enlargement as well as promotion of root formation was about 15.7 mg/kg in the soil and is considered high because it is higher than the critical level of 8.50mg/kg. J1 Forest Reserve is recommended as the best provenance for raising T. ivorensis amongst assessed natural habitats.
