What affects maize production?
What affects maize production?
Production of maize, especially in the tropical regions, is affected by a number of constraints, including an array of abiotic and biotic stresses, poor soil fertility, lack of access to key inputs (especially quality seed and fertilizers), low levels of mechanization and poor post-harvest management.
What are the challenges in crop production?
Farm production poses a number of challenges for farmers around the world. Food production requires adjustments to rapid population growth, the expenditure of resources, soil degradation, reduced utilization of land and a growing lack of water.
What problems and challenges do Kenyan farmers face?
In Kenya one of the major issues affecting agriculture is the lack of and poor conditions of rural roads linking the farmer´s facilities and the commercialization spots in the country. SOIL FERTILITY. The increase in population of the country has forced the terrain subdivision to be done in smaller land portions .
What are the current challenges facing agriculture?
To gain a clearer perspective of the scale of challenge, here are ten issues that are currently facing modern farmers:
- Climate change.
- The ongoing trade war between the United States and China.
- Rapidly depleting reserves of freshwater around the world.
- The looming food crisis.
- Economic insecurity in the United States.
How does temperature affect maize production?
Warming temperatures speed plant development, shortening the length of growth periods necessary for optimum plant and grain size. This faster phenological development also alters the timing of maximum plant water demand. Farmers could avoid some losses through simple changes to planting dates and maize varietal types.
How does climate affect maize production?
At a high temperature of 35°C, maize yield reduces by 9% with a one-inch reduction in rainfall [23]. Thus, even if plant breeders have developed maize varieties that grow well under different biophysical environments [33], sound maize productivity is still under threat by climate change effects.
What are the growing challenges of organic production?
A recent review of organic farming listed several challenges facing organic agriculture (Halberg et al. 2005a) including: • ecological justice; • animal welfare; • fair trade; • supply chain development; • productivity limitations; and • regional adaptation and global harmonisation for standards.
What challenges do farmers in East Africa face?
There are some peripheral needs that have to be tackled at a large scale to aid the farmers all around Kenya. One of the main issues in this regard is the lack of and the poor conditions of rural roads linking the farmer´s facilities and the commercialization spots in the country.
Which is the best farming in Kenya?
8 Profitable farming ventures on just ¼ acre of land in Kenya.
- Mushroom farming. Mushroom farming is not very old in Kenya.
- Garlic farming. Garlic is a high value horticultural crop.
- Fish farming.
- Poultry.
- Passion fruit farming.
- Greenhouse farming.
- Dairy farming.
- Bee keeping.
How does temperature affect crop production?
High temperature, even for short period, affects crop growth especially in temperate crops like wheat. High air temperature reduces the growth of shoots and in turn reduces root growth. High soil temperature is more crucial as damage to the roots is severe resulting in substantial reduction in shoot growth.
Why is maize the most important food in Kenya?
Maize Production in Kenya. Maize is the most important cereal crop in sub-Saharan Africa. It is a staple food for an estimated 50% of the population. It is an important source of carbohydrate, protein, iron, vitamin B and minerals. Africans consume maize in a wide variety of ways (porridges, pastes and beer).
What are the challenges in the production of maize?
Production of maize, especially in the tropical regions, is affected by a number of constraints, including an array of abiotic and biotic stresses, poor soil fertility, lack of access to key inputs (especially quality seed and fertilizers), low levels of mechanization and poor post-harvest management.
How long does it take to fertilize maize in Kenya?
In Kenya 2 weedings are necessary for most maize varieties, though a third weeding may be necessary for varieties that need 6 to 8 months. Weeding by hand requires a minimum of 25 man-days/ha. Irrigation is used in areas of low rainfall and is particularly valuable at the time of tasselling and fertilisation.
How does delayed planting affect yields in Kenya?
Delayed planting always leads to reduced yields. In Kenya there is a drop of expected yields of 1-2% every day planting is delayed (AIC 2002). Planting can be done either be hand or be mechanized depending on the scale of production and farmers capability. Hand planting requires 5-10 man-days/ha.
