The effects of relative planting dates of legumes on productivity of cassava - legume intercrop
… after planting until physiological maturity. Yield and yield components tor cassava such as root weight, root diameter, root length, shoot weight and number of roots was measured at 10 months after planting. Yield and yield components tor legumes such as shoot biomass, number of pods per …

Effect of planting depth and cutting orientation on growth and yield of sweet potato (Ipomoea Batatas L.(LAM) cultivars for small scale production in Verulam
… potato (Ipomoea batatas L. (Lam) is an important root crop for small scale farmers in the KwaZulu-Natal province of South Africa. However, low storage root yields in small scale farming are attributed to a number of factors including poor selection of cultivars and possibly unsuitable cultivation …

Genotypic variation in water use efficiency, gaseous exchange and yield of four cassava landraces grown under rainfed conditions in South Africa
… in water use efficiency, gaseous exchange and yield among four cassava landraces grown under rain-fed conditions. Two field experiments were conducted during the wetter (2016/2017) and drier (2017/2018) cropping season at the University of Venda's experimental farm. The trials were laid in a …

Current and potential systems for maintaining sweetpotato planting material in areas with prolonged dry seasons: a biological, social and economic framework
… early was beneficial as it resulted in increased root yield, an early source of food and sales at high prices. The Triple S (Sand, Storage and Sprouting) method of producing ample planting material for early season planting was developed in Uganda after testing various ways of storing the roots …

Predictive Modeling of Sugarbeet Quality Using Vegetative Index, Statistical, and Artificial Neural Network Methods
… recoverable sucrose contained within the plant root. Earlier studies have focused on root yield with little or no regard to sucrose concentration. Economic benefits are realized by both the processor and producer when processing sugarbeets with high sucrose concentration in the root biomass. …

Impact of Sweet Potato Feathery Mottle Virus and Micropropagation on Yield, Root Quality and Virus Incidence in Commercial Sweetpotato Production Systems
Reduction in yield and root quality (decline) in sweetpotato has been attributed to the accumulation of viruses and mutations. Three studies were initiated to assess the effects of mutations and viruses in sweetpotato. In the first study, to document the effects of decline over time, two …

The response of sugar beet (Beta vulgaris L.) to planting method and sowing date
… the causes underlying the variations in sugar yield associated with treatments. The development of leaf area index (LAI) was examined in different planting methods during the 1981/82 season. Detailed measurements of leaf number, leaf death and leaf area were made and the expansion growth of …
