Abstract:

This dissertation studies agricultural input intensification, defined as the increased use of modern inputs such as hybrid seeds, mineral fertilizer, herbicide, and pesticide in African agriculture. It also analyses the potential of this intensification to accelerate productivity growth and tests the effectiveness of two policies, input subsidies and land reforms, in promoting it and consequently in increasing crop yield. In the first essay, we argue that to create the conditions for the emergence of a green revolution in Africa, modern agricultural technologies have to be adopted as a package

Abstract:

<p> This dissertation aims to explore the current trends in agricultural productivity and analyse its impact on the global farm and food system. Chapter 2 in this dissertation looks at the current trends in agricultural productivity in India—one most of the populous country in the world. In this chapter, productivity trends in Indian agriculture are examined by looking at changes in Total Factor Productivity—a measure which takes into account all farm outputs and inputs. Estimates in this chapter suggest that TFP growth for the 10-year period—between 1999-2000 and 2009-2010&m

Abstract:

<p> The greenhouse industry is interested in light emitting diodes (LEDs) as a light source supplement to solar light to improve plant growth and development. Before LEDs can be adopted as supplemental light for greenhouse crops, plant responses to LED spectral quality need to be investigated. Tomato and cucumber seedlings were grown under different supplemental blue and red photon flux ratios (B:R ratios) under high (16-19 mol m<sup>–2</sup> d<sup> –1</sup>) and low (5-9 mol m<sup>–2</sup> d<sup>–1 </sup>) solar daily light integrals (DLIs).

Abstract:

<p> Among all nutrients that are important for crop production, nitrogen (N) is one of the least efficiently utilized, mainly due to its high mobility in soil. The possibility of using crop sensing in real-time to detect variability in N deficiency within a field has the potential to enhance N efficiency, increase crop yield, and reduce potential environmental risks and crop production costs. Potassium (K), another important crop nutrient, can also lead to higher yield when applied in the right amount and manner.

Abstract:

Agricultural production in France has increased considerably since the late fifties, turning France into a net exporter in world markets. This has generated a heated policy debate between France and the United States, centering around different views of the sources of growth in French agricultural production between 1960 and 1984. To shed some light on this debate, these sources of growth were analyzed. A sectoral model of the French agricultural sector is developed. It is based on the assumption of profit maximization.

Abstract:

Agricultural research is susceptible to research deterioration due to biological, climatic, and economic forces. Research deteriorates as the base conditions it addresses change which leaves the resulting information or technology less effective, efficient, productive, and/or relevant. Maintenance research targets deterioration in an attempt to prevent any loss of previous gains. Maintenance research is in contrast to productivity enhancing research which attempts to increase efficiency or productivity beyond previously attained thresholds.

Abstract:

The aim of this thesis is to provide a differentiated view of peri-urban agriculture in the context of urban population growth in Asmara, Eritrea. Peri-urban agriculture is viewed as a distinct type of broader urban agriculture, and in this case is not as subsistence-orientated as other branches of it. Urban population growth is comprised of three elements, namely, natural population increase, rural-urban migration and outward movement of people to the urban periphery linked to urban expansion. Each receives extensive treatment. Asmara is the capital city of Eritrea and using Weeks (2004:473)

Second, for an enhanced understanding of tree health and related environmental conditions, an analytical methodology should be defined to cluster street trees with similar growth patterns. Third,

This will especially be true if canola production is expanded to irrigated areas.

Abstract:

In jojoba, flower buds are typically produced at every other node on new growth near branch tips.

Treatments involving pinching and untreated control plants were also included. The growth regulators had a significant effect on both branching and flower bud production

It is shown that acreage expansion, population growth and improvement in yields led to rapid recovery in agricultural output in Turkey, whereas the increasingly intensive cultivation in Egypt was only able to offset the impact
