The results of this study indicate that the extraction temperature greatly affects the pectin yield, water content and methoxyl pectin while the extraction time affects the pectin water content. At a temperature of 70OC and an extraction time of 60 minutes, the highest average yield of pectin was obtained, namely 4.31%, while the lowest average yield of pectin was obtained from the treatment of an extraction temperature of 90OC and an extraction time of 90 minutes.

Farmers live in remote rural areas and make up 75% of the world’s poor. In Sub-Sahara Africa (SSA), productivity in agriculture lags behind globally, and is below the required standards of achieving food security, poverty goals and food sufficiency. As an important sector in the Kenyan economy, agriculture continues to dominate other sectors despite its declining contribution to real GDP. The development in agriculture is that one which revolutionizes the industry by bringing forth profitable agriculture and environment friendly solutions. Kenya government through the Ministry of Agriculture and Livestock, have in the past tried to pass information to the farmers via agricultural extension officers. However, the quality of the information disseminated to the farmers has not been up to date, information delivery has not been good, the mode of communication also questionable owing to literacy levels of our farmers and indeed that of the extension officers, information technology has not been embraced fully making it difficult for our farmers to progress with their counterparts in other parts of the world. This study was conducted with the aim of determining the factors impacting agricultural production and the role of agricultural extension services in Kenya. This study is anchored on Diffusion of Innovations Theory. The study employed a mixed design involving a combination of both quantitative and qualitative approach. And the target population was made up of farmers, officers from the ministry of agriculture and officers from agricultural extension service providers. Data was gathered using both structured questionnaire and interview guides. The collected data was analysed with the aid of SPSS software using both descriptive and inferential statistics. The findings revealed a coefficient of determination (R squared) of 0.319 implying that agricultural extension services explains 31.9 % of the variation in agricultural production in Kenya. The study also showed a positive and statistically significant relationship between agricultural extension services and agricultural production in Kenya (β=1.561, p=.003<.05). The study concludes that agricultural extension services play a significant role in improving agricultural production in Kenya because agricultural extension services offers technical advice on agriculture to farmers. It is thus recommended that agricultural extension service delivery should be boosted through timely recruitment, periodic training of agents and provision of adequate logistics to the farmers.

Tea pickers are workers who really need their existence, considering the quality and quantity of tea depends on how they work. The wages of tea pickers are very low due to the small amount of picking weight produced because the picking system is still done manually. The purpose of this study was to determine the effect of manual picking mechanization and using scissors on the wages earned by pickers. Sampling was done randomly and analyzed using multiple linear regression. The results showed that there was a significant difference between the picking system and the wages of the pickers. The use of picking scissors can increase wages by 40.18%.

Nitrogen at three levels (20, 60, and 100 kg pure nitrogen per hectare) from urea and phosphorus fertilizer source at two levels (zero and 75 kg P2O5 source per hectare) from monopotassium phosphate fertilizer source and planting row spacing at three levels (30, 45 and 60 cm) equivalent to 47, 31 and 24 plants per square meter, plant density were considered. The results showed that nitrogen, phosphorus, and planting density significantly affected all traits. Planting row spacing affected all characteristics except seed gum and phosphorus levels were effective on all traits except glycine betaine and leaf sodium. The highest yield components and seed gum were obtained from N3P2D3 treatment (application of 60kg/ha nitrogen, 75 kg/ha phosphorus, and 60 cm row spacing) which was no different from N2P1D3 treatment and the highest leaf proline content was related to N2P2D3 treatment and the highest glycine content was betaine and leaves. Sodium was related to N2P1D3 treatment. The highest grain yield and yield components in the first and second year of N2P2D2 treatment (application of 60 and 75 kg of nitrogen and phosphorus, respectively, with a row spacing of 45 cm) were obtained at 4300 and 4200 kg/ha, respectively, with N3P1D2 and N3P2D2 was not significantly different. The highest levels of carotenoids and chlorophyll a and b were related to N3P2D3 treatment.
