Dryland horticulture notes


This is the old United Nations University website. Management strategies for drylands: available options and unanswered questions. Low productivity per land unit is a salient feature of most dryland ecosystems. Limited rainfall inputs, small and highly localized surface water resources, scanty or non-existent vegetation, and low population totals combine to place constraints on the total productive capacity of both the cultural and physical components of dryland eco-systems. These constraints tend to encourage the development of relatively low-intensity, extensive resource-use systems. However, there are exceptions to these low productivity situations.

Agricultural Reviews

As livestock and grain producers face increasing seasonal variability, up-to-date information on soil moisture is becoming highly valued in support of tactical decision making. This has been shown by the use of the department's soil moisture probe network by the Victorian dryland grains industry to make a range of farm decisions over the past six seasons. Each site is monitored using capacitance probes which take hourly measurements of soil water content through the soil profile.

Sensors in the capacitance probe measure 10cm soil zones, from a depth of 30cm down to 1m. Repeatable measurements from each sensor are recorded at the site, and the data collected are sent via the mobile phone network to a server, which stores the data to allow interpretation using graphing software.

And the story continues to get better, with progressively better data being generated in new and varied seasons.

Knowledge of deep soil moisture conditions can help the grains industry make tactical decisions about:. By far the most important use is in making decisions about inputs — for example, minimising input in years with a low soil moisture base, and maximising yield potential under more favourable conditions. This is based on current soil moisture levels, understanding of Victoria's climate drivers and incorporation of seasonal forecast probabilities. A soil moisture speedo is used to show how the season is progressing, with the gauge needles showing changes in the past month and comparing the conditions with those of a year ago.

Cropping confidence improves when the needles increase in May to August, indicating that rainfall exceeds plant demands and builds up moisture reserves that can be used later for critical crop growth periods flowering and grain fill. How can pasture and sheep producers use this type of technology to make informed tactical decisions? Some great research and extension has already been conducted in south-west Victoria by Malcolm McCaskill, examining soil moisture and pasture production.

This will be validated at the Lake Bolac monitoring site in the coming years. The Lake Bolac site has been sown down to pasture this season after five years of monitoring winter crop and soil — water interactions. This is a unique opportunity to compare historical annual versus perennial plant growth and moisture use, and the effect of canopy management associated with grazing systems. Winter crops in spring, with a large biomass and available soil moisture, can deplete large moisture reserves.

What will the pasture moisture use be like? The farmer host hopes that pasture growth continues to mid to late December because then sheep can go onto crop stubbles. Early signals from the moisture probes of soil moisture conditions can provide indications of pasture production because half the spring production is based on soil moisture, with the other half coming from rainfall.

Fortunately, knowledge of both of these has improved, which is where the moisture probes in pasture situations could have a great fit. Yellow highlights in the x axis date sequence shows the dry year of and the red marker indicates the limited deep soil moisture accumulated in that year.

The green shaded area is plant available water and this site has consistently obtained maximum water holding in most winters. One decision that could be considered with knowledge of soil moisture levels is the culling rate of sheep in August, when the feed outlook identifies feed gaps.

Urea application can also be a strategy in dry springs, such as , to increase feed production during the period of reliable soil moisture, and to boost hay and silage yields. Nitrogen application should be considered as part of the feed budget rather than the fertiliser budget, because it is an alternative for supplying additional feed at times of forecast shortage. Live data for all Agriculture Victoria crop and pasture sites, including moisture speedos and soil temperature is available on the ExtensionAus website.

Knowledge of deep soil moisture conditions can help the grains industry make tactical decisions about: crop types sown time of sowing upfront and in-crop management inputs particularly nitrogen crop salvaging for hay in dry years grain marketing. Potential uses for livestock graziers include decisions about: selling or buying livestock early purchasing supplementary feed nitrogen applications.

Though it is a dryland crop, it requires irrigations only in summer season from March to May at an interval of 15 to 20 days for fruit retention and maturity Mango requires slightly deep soils with good drainage and pH at 6. It needs 10m x 10m spacing in well deep soils and 9m x 9m in medium deep soils. Allied Agriculture Dryland Horticulture. Certain crops such as ber, custard apple, amla and mango require less water and can be grown as rainfed crops. With supplemental irrigation pomegranate and mango can be used for alternate land use systems. These orchards can be intercropped upto 3 years to generate more biomass. Can be grown on any type of soil.

The blocks namely Thiruvattar and Melpuram were major Plantation Crops growing region and Thuckalay, Thovalai and Kurunthancode were major Fruits growing region. To increase the production, productivity and income of farmers, various schemes are being implemented through Department of Horticulture and Plantation crops. A beneficiary can get financial assistance up to 5 ha. Farmers who are all already benefited can also get subsidy for renewal of laterals after seven years. In this, subsidy is extended for creation of ground level water storage structures Rs.

Dry farming is cultivation of crops in regions with annual rainfall less than mm.

Horticultural Science is the most distinct branch of Agricultural Sciences and call be divided into four different branches as follow. Chilli and seed spice Research Station of Horticulture of Telangana. To develop horticulture to the maximum potential available in the State and to augment production of all horticultural production of all horticultural products Fruits, Vegetable, flowers, Plantation crops, Spices, Medicinal Aromatic plants in the state. In pursuance of the above goals, the National Horticulture Mission will focus in the areas of horticultural research, development, post harvest management,, processing and marketing. Mains Test Series and Notes.

Horticultural crops demand and require significant amounts of water due to their perishable nature. Tree fruit and nut crops are not only comprised of large amounts of water, but the trees are perennial plants. Vegetables are also quite perishable but they represent annual crops and thus only one year of production is affected. Since water is such a critical component of the growth and development of horticultural crops, it is recommended that none of these crops be established without full irrigation capabilities.
