A study of water use efficiency in field crops of Maize and beans

Crop water use efficiency nay be defined aa the ratio of total dyy matter produced to total evaporation from the orop and the aoil.

The Effects of Tillage and Residue Mulching on Soil Moisture Conservation in Laikipia, Kenya

The effects of selected soil management practices (conventional tillage, tied ridging and crop residue mulching) on soil moisture conservation in a semi-arid area of Kenya (Kalalu, Laikipia) were studied during the short rains period, 1988, and long rains period,1989. Two test crops maize and beans were used to monitor the effects of conserved moisture on crop performance (emergence,height and ground cover) and yield.

Susceptibility Of Locally Grown Maize Varieties To Maize Weevil (sitophilus Zeamais Motsch)

Storage insect pests of maize cause weight and quality loss. Although insecticides and fumigants are available, use of resistant varieties is preferred due to low cost, have no adverse effect on environment and leave no toxic residues on food products. The objective of this study was to evaluate locally grown maize varieties for susceptibility to maize weevil (Sitophilus zeamais Motsch). Sixteen varieties were screened in the laboratory and field over two growing seasons.

Some aspects of production and marketing of sunflower in Kenya

This thesis is mainly the outcome of a field survey based on administration of questionnaire, verbal interviews as well as on-the-spot observation and analysis or available published information. The first task was to establish the degree of current production, and possible potential production. Sunflower has been grown in Kenya for many years but has never achieved much prominence as an oil crop; in fact the bulk or present production is exported to European and American countries as bird feed.

Influence of farm subsidy on sustainable maize production in Transmara West District, Narok County

This report is on influence of farm subsidy on sustainable maize production in Transmara West District, Narok County. The study was warranted by the continued food deficit in the world where around 925 million out of the total 6.8 billion people in the world are food insecure, 13.1 percent, or almost 1 in 7 people are hungry. From the literature reviewed it was found out that Maize the staple food for many Kenyans has been in the decline over the years. The country suffers a maize deficit of 6.8 million bags (612,000 metric tons).

Determinants Of Maize Yields Among Small Scale Farmers In Trans Nzoia West Sub County, Transnzoia, Kenya

Maize is a global crop. In terms of nutrient formation, maize contains approximately 72% starch, 10% protein, 4% fat supplying 365kcal/100g.It is a staple food in many African countries including Kenya with the largest production from small scale farmers. Investigating to understand the determinants of maize yields among small scale farmers is therefore an important area of study. The purpose of the study was to investigate the determinants of maize yields among small scale farmers in Trans Nzoia West Sub County of Trans Nzoia County in Kenya..

Monitoring Changes In Soil Organic Carbon, Moisture Content, Nutrient Balances And Maize (Zea Mays L.) Yield Following Dolichos (Lablab Purpureus (L.) Integration And Fertilizer Application In Maize Systems Of Nairobi County, Kenya

Decline in soil nutrients and organic levels due to continuous cultivation practices combined with erratic rainfall patterns has led to soil fertility decline posing a serious threat to long-term maize (Zea mays L.) production in Nairobi County, Kenya. The current study monitored changes in soil organic carbon, moisture content, nutrient status and maize yield following dolichos (Lablab purpureus (L.) integration and application of fertilizers, as basis for developing sustainable soil fertility management strategies.

White Lupin (Lupinus albus L. cv. Amiga) Increases Solubility of Minjingu Phosphate Rock, Phosphorus Balances and Maize Yields in Njoro Kenya

Exudation of high amounts of citrate in white lupin (Lupinus albus L. cv. Amiga) has the advantage of being effective in mobilization of a wide range of sparingly soluble P sources. To improve cultivation system of maize, a field experiment was conducted to assess effectiveness of white lupin (Lupinus albus L. cv. Amiga) in increasing solubility of minjingu phosphate rock (MPR), phosphorus balances and maize yields in Njoro sub-County, Kenya.

An economic analysis of the impacts of trade liberalization on Kenya’s maize sector

Kenya like most other developing countries has been reforming her staple grain markets since 1986. In these sectors, market reforms were initiated as a key component of the economy-wide structural adjustment programmes (SAPs). The SAPs were later strengthened and made irreversible by Kenya’s commitments at the multilateral trade negotiations. The reforms were envisaged to improve the sectors terms of trade as a means of stimulating food production. However, the impacts of trade reforms on Kenya’s maize sector remain controversial.

Impact of statistical quality control on customer loyalty in the Maize and Wheat Flour manufacturing firms in Kenya

Firms are faced with problems arising from emergence of new technologies and shifts in consumer demands. Such problems have increased the complexity and range of issues to consider when making decisions. In an attempt to improve quality and reduce costs of maize and wheat flour, every firm in the industry is striving to cope with such problems and remain competitive.
