Studies in mixed cropping. 1. Seasonal differences in relative productivity of crop mixtures and pure stands in the Kenya Highlands.

In a trial during 4 cropping seasons in 1972-4 at Kabete, yields of maize/bean (Phaseolus vulgaris) and maize/potato mixtures grown in alternate rows were compared with pure stands of the component species. In seasons with low rainfall yields of the mixtures were much lower than those of pure stands, but in the exceptionally wet long-rains season of 1974 the maize/bean mixture outyielded the pure stands. Poor yields of mixtures in seasons with low rainfall were attributed to large decreases in maize grain yield due to competition from beans and potatoes.

Investment Strategies By Kenya Power And Lighting Company Within The Power Distribution Sector

The main purpose of the study is to determine the investment strategies used by Kenya Power and Lighting Company within the power distribution sector. Adequate investment in capacity and efficient working of transmission and distribution systems in developing economies with high growth of electricity demand are important objectives. The literature review available on investment strategies within the power distribution sector have been captured and the theoretical underpinnings of investment strategies.

Effect of increased intimacy between maize and beans in an intercrop system on growth and yield of maize under varying nitrogen levels.

Field Nairobi's experiments Faculty of increasing were conducted at the University Agriculture farm to investigate of the merits plants of the proximity between maize and bean in an intercrop system and how N-fertilizer levels influence this interspecific interaction. Four planting patterns and four nitrogen levels were tested in a factorial experiment and laid out in a completely randomised block design with three replicates.

An Assessment of the Informal Sector Trade in Kenya

This study assesses the nature and practice of cross-border trade in Kenya with a view to filling the information gap on its patterns and key characteristics, a gap that has hitherto acted to hinder effective policy formulation. The study relies on information from a number of cross-border monitoring survey initiatives mounted by various institutions over the years. The study finds that informal cross-border trade accounts for more than 40 percent of the GDP and is therefore almost equivalent to formal trade.

Strategic change management and impact on performance of Unga group ltd

Economic and social forces such as globalization, social/cultural, political/legal, competition, technology, liberalisation, deregulation, unstable financial markets, and advances in information and communication technologies are among the many business environmental factors driving the escalating pace of change evident within organizations today.

Effect of seasonality of feed resources on dairy cattle production in coastal lowlands of Kenya

ABSTRACT In the Coastal Lowlands of Kenya, small-scale integrated crop-livestock system is the dominant form of agricultural production. Feed quantity and quality are inadequate and rarely meets the nutrient demands of lactating cows especially, in the dry seasons. The objective of this study was to determine the effect of seasonality on availability and quality of feed resources on dairy cattle productivity in Coastal Lowlands of Kenya.

A micrometrological investigation of yield differences in alley cropping trials in the semi - arid areas of Machakos District

A micro meteorological study was carried out at the National Dryland Farming Research station at Machakos, Kenya, to assess the potential of alley cropping Katumani Composite B maize with cassia siamea as a low-external input technology for farmers in a tropical semi-arid environment. The experimental layout was a completely randomised design with three treatments which were replicated four times. Three rows of maize were planted in each alley formed by four Cassia siamea hedgerows.

Evaporation from soils below sparse crops in contour hedgerow agroforestry in semi -arid Kenya

In many agricultural systems in the semi-arid tropics, crops use only a small fraction of the total rainfall. Agroforestry can greatly reduce some losses, especially on hi II slopes, where soi I evaporation, runoff and soi I losses are important. This paper repoi [S on soi I evaporation from a rotation of intercropped maize and cowpea between contour hedgerows of pruned Senna siamea trees as well as trimmed Panicuni maximum grass strips on a 14% hill slope at a semi-arid site in Machakos, Kenya.

Influence of soil parent materials and extent of weathering on plant available potassium and uptake in maize along a Kisii topo-sequence

A study was conducted on relationship letween chemical and mineralogical ~operties of basalts, trachytes and rhyolites and soils overlying them with regard to catIOns (Ca2+, Mg2+ and K+) and clay variation with depth, plant available K in !urface soils and maize K uptake in an exhaustively cropping greenhouse experiment. Mean Ca2+, Mg2+, and clay wntents were significantly different (P ~.O5), and decreased in the order of soils ~eveloped from basalts trachytes rhyolites. Mean K differences were not ~gnificant at P 0.05.

Supply of Kenyan Pyrethrum

Kenya's pyrethrum industry provides self employment to over eighty thousand rural families. Over two thousand people find wageemployment in the Pyrethrum Marketing Board's factory. Others earn regular incomes from collection and transportation networks. Pyrethrum is Kenya's fourth most important export crop, accounting for about SlX per cent of .Kenya's total foreign exchange earnlngs each year. Knowledge of farmers" responsiveness to changes in economic variables is iQportant in formulating agricultural policies.
