Fruit farming is an important venture but becomes more interesting and profitable when it is done as an agribusiness. There are various ways in which you can improve your hass avocado productivity. These include;
When growing hass avocado for commercial purposes, climate plays an important role in determining if your plants thrive. They should be planted in a suitable climate that favors avocado farming for optimum production. Hass avocado thrives in average temperatures ranging from 140C to 270C. The plant requires high humidity, especially during the flowering and fruit setting stage.
Constant Irrigation of Hass Avocado
Soil moisture is an important factor that should be taken into consideration in hass avocado farming. During vegetative growth, avocado orchards grow vigorously and require constant irrigation. During the dry season, reduced irrigation slows down the growth rate. In poorly drained soils, the plants should be irrigated at a controlled rate to enable them to take up water efficiently and to minimize waterlogging. Avocado plants are sensitive to frost and hence water stress should be minimized during the flowering and fruiting stage.
Hass avocado plants require nutrients throughout their growth. Although they can grow in all types of soils, they perform better in fertile and well-drained soils. Organically, this can be done by applying manure regularly. Plants respond well to heavy manure application, especially when it contains high nitrogen content. Fertilizers should be applied based on soil and leaf analysis. A complete soil analysis should be conducted a few months before planting to check the nutrient status. Also, an irrigation water analysis and leaf analysis should be conducted. The soil nutrients status, plant size, water quality, plant density, soil nutrients status, and yield expectation determines the type of fertilizer required by the hass avocado plants. However, fertilizers should not be applied to early on young transplanted trees. Fertilizers should be applied when the plants are properly established and growing vigorously. To ensure optimum results, fertigation should be ensured for irrigated hass avocado trees to enable even distribution of fertilizers.
Important Nutrients Required by Hass Avocado
Nitrogen, Potash, and Phosphorus should be applied regularly to the plants especially during vegetative growth. Avocado trees also require Magnesium, Zinc, and Sulphur. For instance, Urea should be applied at an interval of 3-4 months. Nitrogen deficiency causes early leaf shedding, pale, small leaves, slow growth, and yellowing of veins in severe cases. Too much nitrogen, however, results in excessive vegetative growth and reduced production. Regular leaf analysis should be conducted to determine when nitrogen application is required. To achieve healthy production and an excellent growth rate, inorganic fertilizers should be applied along with manure.
Pests and Diseases control
The most efficient and economical method of pest and disease control is prevention. These preventive measures include weed control, proper selection of planting material, maintaining optimum plant density and proper fertilizer application. The presence of pests in avocado plants reduces productivity significantly.
Pests in avocado production are not common in Kenya. Pest control rarely requires chemical control. To improve avocado productivity, pests and diseases should, however, be controlled. Some major pests that attack avocado include:
- Scale insects
- False codling moth
Fungal diseases also affect hass avocados and need to be controlled early enough. Major diseases are:
- Anthracnose. It attacks fruits especially the mature ones forming dark brown spots. It can be controlled by using fungicides such as Mancozeb, Triforine, Metiram, and Benomyl.
- Root Rot. This disease is common in flood-prone areas and places with poorly drained soils and attacks the roots. Some preventive measures include planting grafted hass avocado seedlings. Chemically, it can be controlled using chemicals such as Aliette and Ridomil.
- Cespora Fruit Spot. The disease attacks fruits and leaves leaving yellow spots on fruits later on turn brownish. It can be controlled with copper-based fungicides such as Mancozeb, Benomyl, and Trifoline.
- Scab. It mainly attacks twigs, leaves, and fruits. It can be controlled by spraying fungicides such as Mancozeb and Triforine.
Other Factors Influencing Productivity
Mulching minimizes soil erosion especially in sloping orchards and minimizes water loss through evaporation. This will help to minimize moisture stress.
Spacing is a key factor in maintaining and maximizing productivity. Good spacing helps in ensuring aeration in the orchard. High-density plantation results in higher production although it leads to problems in canopy cultivation in later years.
Avocado trees are not self-pollination plants in nature and hence require artificial pollination for fruit production. Cross-pollination with another cultivar is important for the best fruit setting. Practicing bee farming near avocado farms can improve pollination in hass avocados.For the All type of Fruit tree seedlings We at oxfarm we do propagate and sell quality certified seedlings to farmers at the best prices for each seedling as above.
