Not only were technical solutions to the Cyperus problem sought, but work was also done on the economics, acceptability to farmers and promotion of this technology. Vertisols represent a vast crop production resource. It is estimated that there are at least million ha of these montmorillonitic clays in the world, located mainly in Africa, Australia, India.

In West African countries like Ghana, where crop production depends largely on smallholder farming and rainwater, the need for better weather and climate information systems is significant [3,[ The use of synthetic fertilizers to increase crop production in SSA is still very low because of various market, climatic, and soil-related conditions, and yet population growth rate outstrips food production (Liverpool-Tasie et al.,Mwangi, ).Farmers in SSA use less than 10 kg nutrients per ha compared with 73 kg in South America and up to kg in Asia (Marenya and.
Ideas about the role of smallholders have evolved over time, and this role is increasingly being seen in a broader economic context. The discussion about smallholder farms should be expanded beyond a strict focus on small versus large farms, to reflect the idea that optimal farm size is a dynamic concept that changes as a country’s overall economy grows and as non-agricultural sectors develop.

Management of Nutrients and Water in Rainfed Arid and Semi-Arid Areas for Increasing Crop Production was implemented between and with the overall objective of increasing crop production through improved management of nutrients and water in rainfed arid and semi-arid areas.
Background 1 2. Integrated Soil Fertility Management (ISFM) is an approach based on the following principles: Neither practices based solely on mineral fertilizers nor solely on organic matter management are sufficient for sustainable agricultural production. contribution (indc). ‘rainfed farmers are the most neglected’ - the hindu even though rainfed agriculture contributes to 60 per cent of the value of agriculture gdp of india, there is a clear-cut bias towards irrigated areas when it comes to public investment in rainfed agriculture - wikipedia rainfed agriculture is a type of farming that relies on rainfall for water.

Conservation agriculture (CA) is an approach developed to manage farmland for sustainable crop production, while simultaneously preserving soil and water resources (Erenstein, ).
Generally, conservation agriculture relies on three major principles: maintenance of a permanent vegetative cover or mulch on the soil surface; minimal soil.
The aim of conservation agriculture (CA) is to improve soil quality and crop yield whilst reducing runoff and topsoil erosion. An experiment was carried out in a rainfed field using a permanent raised bed planting system for 3 yr (–) in Adigudem, northern Ethiopia in order to evaluate the effect of CA on runoff, soil loss and crop yield.

rotation crop which can replace maize as a monoculture crop since it enriches the soil with nitrogen. Secondly it is a crop with high economic value which can fetch a high price on local markets. Groundnut production requires more management skills than many other crops.
Successful farmers are those who apply the prescribed management. In Africa, where most agriculture is rainfed, crop growth is limited by water availability. Rainfall variability during a growing season generally translates into variability in crop production.
While the seasonality of rainfall in the drier rangelands can play a significant role in productivity, rain-use efficiency (RUE)—the amount of biomass produced (in kilograms of dry matter per hectare.
A recent review of over 30 field- and community-level case studies on investments in small-scale irrigation (Table ) found that targeted investments in agricultural land and water management and associated policy interventions could double or even triple rainfed crop yields in sub-Saharan Africa and South Asia while generating additional net.
Therefore, this study was initiated with the objectives of identifying nutrient limitations through soil analysis and wheat nutrient status. The results of the study serve in making suggestions on improving fertilization and soil management to achieve sustainable crop production on Vertisols of the central highlands of Ethiopia.
There is a need to focus on crop improvement and integration of crop and agronomic management strategies for achieving higher gains in the stressed environments. Dr C Scott of IWMI discussed the land and water management theme for enhanced rainfed cropping for improving production.
The utihsation and management of Vertisols for rainfed crop production has become increasingly important as these soils represent a large and valuable resource with tremendous potential to increase the reliability of crop production particularly in many semi-arid regions (for example, 90 Mha of Vertisols in Africa).
Vertisols are tropical soils that occur world-wide ( million ha) with high agricultural and other engineering potentials. However, they are underutilized as most of their physical characteristics make management techniques difficult and highly localized.
This paper aims to highlight the characteristics, genesis and management strategies of Vertisols for sustainable use. Smart Technologies for Sustainable Smallholder Agriculture: Upscaling in Developing Countries defines integrated climate smart agricultural technologies (ICSAT) as a suite of interconnected techniques and practices that enhance quantity and quality of agricultural products.
But although this may be the case for crop diversification with several crop mixes and adoption of agricultural technology such as modern varieties, the increase in farm size may also lead to specialisation with fewer and more specialised high‐value crops or cash crop production.
Sustainable intensification of cassava production is the subject of this guide, the first in a series to the practical application of FAO’s “Save and Grow” model of agriculture to specific smallholder crops and farming systems.

potential for rainfed agricultural development (Global Yield Gap Atlas ). Nitosols (23%), Cambisols (19%) and Vertisols (18%) are the major agricultural soil groups in Ethiopia (Dubale ).
About 11% of total cultivated land is used by more than 6 million smallholders to produce non-food products. Cereal production occupied about. In the African subtropical zones, the choice of tillage practice is critical to sustainable rainfed crop production. Two season ( and ) field trials were conducted at Matopos Research Institute (20°24′S; 28°29′E, m above sea level) in southern Zimbabwe in order to determine dryland grain sorghum yield and kernel weight responses to tillage and mulch practices under.

The soils are very productive but need special management in terms of Title: Independent Consultant at PwC. The consequences of climate change on smallholder farms are locally specific and difficult to quantify because of variations in farming systems, complexity of agricultural and non-agricultural livelihood activities and climate-related vulnerability.
One way to better understand the issues is to learn from the experiences of farmers themselves. Thus, this study aimed to better understand.
For sustainable land management, strategies for adapted crop production systems are needed. In agronomic field trials, the potential of enhanced water use efficiency as contribution to a resilient agricultural system under changing climate conditions was evaluated and related to the common practice and regional research.
crop yield in Ghana. A study conducted by Mabe () indicated that climate change is evident in Northern Ghana. Mendelsohn () and Smit and Skinner () have demonstrated that without adaptation, agricultural production will be severely affected by climate change with the resultant effects of making farmers more.
The population of Africa will double in the next 33 years to reach billion by Although roughly 60% of the continent’s population is engaged in agriculture, the produce from this sector cannot feed its citizens.
Hence, in alone, Africa imported million tons of wheat, maize, and soybean at the cost of billion USD. Although crops cultivated in Africa play a vital role. The yield of rainfed crops is characterized by its high variability due to the high variability in seasonal rainfall (total annual country average ≈ km3).
Accordingly, farmers adopt low-input rainfed agriculture as a risk management option. This reduces the yield per unit of land and water.Realizing the benefits of cover crop legumes in smallholder crop-livestock systems of the hillsides of Central America  Scale factors and smallholder competitiveness  Sustainable food–feed systems to improve livelihoods among the poor in the rainfed lowlands .
