Allometric relationships and carbon content for biomass-carbon estimation of East African Highland Bananas (Musa spp. AAA-EAHB) cv. Kibuzi, Nakitembe, Enyeru and Nakinyika
Globally, interests to increase carbon stocks have gained momentum in both woody and non-woody ecosystems. Despite efforts made to generate appropriate methods to estimate these stocks, most equations developed do not cater for intraspecific variabilities across e.g. species, regions or growth stages; especially in the case of bananas. Therefore, there is need to develop more robust equations to improve on the precision...

Performance of varieties of green manure in conventionally used soil
The objective of this research was to evaluate the performance of different types of summer green manures in conventionally used soil. This research project was carried out in the district of Concepción (Paraguay). A Randomised Complete Block Design (RCBD) was used, consisting of four treatments and five repetitions. The treatments were Mucuna pruriens (T1); Canavalia ensiformis (T2); Dolichos lablab (T3) and...

Response of potato to different soils and fecal matter fertilizers
Potato (Solanum tuberosum L.) is an important food and cash crop in Kenya. However, its production has declined over the years due to extensive nutrient mining without adequate replacement. A study was conducted to evaluate the response of potato grown under three soil types (Planosol, Andosol and Acrisol) using three fecal matter fertilizers (FMFs). This included vermicompost, normal compost and dried sludge. In...

Factors affecting the adoption of agricultural innovations on underutilized cereals: The case of finger millet among smallholder farmers in Kenya
Agricultural innovation adoption is fundamental in increasing incomes and food output in developing countries. However, the factors that influence farmers’ decisions to adopt innovations in underutilized crops are not well-documented. Underutilized crops like finger millet have been an alternative form of sustenance for resource-poor farmers especially in arid and semi-arid areas in Kenya. They are more nutritive...

Productive capacity of Brachiaria brizantha (Syn. Urochloa brizantha) cv. Marandu subjected to liming and nitrogen application
This work aims to evaluate production of Brachiaria brizantha (Syn. Urochloa brizantha) cv. Marandu subjected to liming and nitrogen fertilization on climatic conditions in the municipality of Humaitá State of Amazonas, Amazônia, Brazil. For both, pot experiment with soil after sowing was kept in a greenhouse at the Institute of Agriculture and Environmental Education (IEAA / UFAM). Part of the soil pots...

Soil nitrate, phosphorus and potassium concentration after four years of liquid swine manure application on Tifton 85
One major problem of swine production is the huge volume of manure generated; this involve difficulties in proper handling of the residue when applied to the soil, given that such elements can be toxic to the environment. This study examined the vertical movement of the P, K and mineral N in the soil profile cultivated with Cynodon dactylon cv. Tifton 85 which was submitted consecutively to rates of Liquid Swine Manure...
