Allelic Variation of Terpene Synthases Drives Terpene Diversity in the Wild Species of the Freesia Genus.
(2023-03-18)Terpene synthases (TPSs) play pivotal roles in conferring the structural diversity of terpenoids, which are mainly emitted from flowers, whereas the genetic basis of the release of floral volatile terpenes remains largely ... -
Bradyrhizobium inoculation has a greater effect on soybean growth, production and yield quality in organic than conventional farming systems
(2021-06-22)Globally, organic farming and bradyrhizobia inoculation are gaining popularity as agronomically and environmentally sound soil management strategies with great potential to alleviate declining soil fertility, maintain ... -
Do Mixed-Species Legume Fallows Provide Long-Term Maize Yield Benefit Compared with Monoculture Legume Fallows?
(Wiley, 2009-11-01)The deliberate planting of fast-growing N2–fixing legume monoculture species in rotation with cereal crops can be an important source of N for soil fertility replenishment. We hypothesized that mixed-species fallows have ... -
Organic and Mineral Input Management to Enhance Crop Productivity in Central Kenya.
(2009-09)Organic resources (ORs) are important nutrient inputs in tropical agriculture. Combined with mineral fertilizers, they form the backbone of integrated soil fertility management. This study was conducted to determine the ... -
Effects of blended fertilizers on soil chemical properties of mature tea fields in Kenya
(2018-06)Kenya’s tea industry depends predominantly on imported NPK fertilizers to replenish nutrients removed through plucking. In this respect, two blended fertilizers containing NPKS 25:5:5:4+9Ca+2.6Mg and NPKS 23:5:5:4+10Ca+3Mg ... -
Nutrient Budget and Economic Assessment of Blended Fertilizer Use in Kenya Tea Industry
(Hidawi, 2018-11-18)Kenya’s tea industry depends predominantly on imported compound NPK fertilizers to replenish nutrients removed through plucking. These fertilizers cannot be easily manipulated for specific soils and tea clones. They also ... -
