For a profitable watermelon manufacturing, loads of care have to be taken so as to obtain that. A few of the administration practices which allows the right progress and manufacturing of watermelon contains:
1) High quality Seeds
The standard of the seed used for planting is essentially the most essential issue as the opposite elements are primarily based on this. The speed of germination and manufacturing yield of your watermelon farm is basically depending on the kind and high quality of the seed planted.
Subsequently you might be at all times inspired to buy solely prime quality seeds for your watermelon planting because it goes a great distance on figuring out the profitable price of your watermelon farming.
2) Climatic Elements
Watermelons require lengthy heat rising durations because the crops are prone to frost, and likewise be aware that low temperatures could cause progress abnormalities, poor setting and hole fruit.
Disaster like Sunburn could be a very large drawback for the fruit notably within the ‘ground spot’ space if the fruit are positioned the wrong way up after harvest. In response to examine, Gentle inexperienced and grey-green melons are much less more likely to sunburn than the darker inexperienced or striped varieties.
3) Soil Elements
With a effectively ready soil, watermelons might be grown on a variety of soil varieties because the principal requirement is nice drainage.
Good irrigation administration is required when rising on heavy soils so as to decrease plant losses from root rot and Mud sticking to the harvested fruit may make them ugly and might result in discount in market acceptance.

4) Institution and Care for the Watermelon Plant
A canopy crop is very really useful earlier than you plant watermelons and If root-knot nematodes are an issue, then attempt to keep away from legumes solely use cereal crops like forage sorghum as an alternative. Be certain that all cowl crop residues have been damaged down fully earlier than planting the watermelon crop.
Ripping could also be required to enhance drainage on shallow or compacted soils and laser leveling earlier than planting can be really useful. Since watermelons are sometimes used as a fast rotational crop, you might be inspired to hold out a analysis on the cropping historical past of the bottom you might be planting on to make sure no carry-over herbicides have been used.
Within the case of sugar-growing districts, it is best to notify surrounding cane farmers of the crop’s presence to stop harm from herbicide spray drift.
Plastic mulch, in addition to drip irrigation and containerized seedlings, is broadly utilized in watermelon manufacturing. The plastic mulch used can range from 0.9 to 1.2 m in width and is used to cowl the plant row.
Soil within the rows is normally raised about 10 cm in top and the drip tape laid down the centre of the row or barely to the facet then each the bedding up and laying of the drip tape might be carried out throughout or previous to the laying of the plastic.
5) Planting Elements
Watermelon planting is carried out by direct seed sowing within the subject or with using containerized seedlings. Since a lot of the industrial types of watermelon seeds are hybrids, the latter method is most popular due to the excessive value of hybrid seeds.
Wherever plastic mulch is used then the direct seeding machines on waterwheel planters are additionally used thereby punching the seed or seedlings instantly by means of the plastic mulch and for direct sowing then roughly 1.5-2 kg/ha of seed is required.
Pre-germinated seeds can be utilized to re-plant anybody that didn’t germinate, the row spacing varies from 1.5m-3.0m and the plant spacing varies from 0.75m-1.5m. Seedless melons require a regular selection in shut proximity to supply pollen so as to allow fertilization to happen.
Additionally be aware that with out pollinators, fruit is not going to set and don’t plant greater than two rows of the seedless selection to each one row of a regular selection and at all times make sure the seedless kind is distinguishable from the usual selection. Watermelon seeds take 4-14 days to germinate and the required soil temperature ought to be not less than 11°C as on the time of planting.

6) Dietary Elements
Soil evaluation is very really useful and within the absence of an entire soil evaluation, an entire fertilizer ought to be utilized by means of spreading and incorporate with (sandy soils) or drilling (purple soils). Additionally use NPK mixes at 700-1200 kg/ha of 5:6:4 or 300-500 kg/ha of 14:14:12 or comparable mixtures, and nitrogen side-dressings.
Keep away from late purposes or extreme nitrogen use in chilly climate, as hole melons could outcome. Extreme nitrogen utility additionally favors the event of male flowers and the place drip irrigation is used, facet dressings are utilized by means of the drip system.
Relying on the outcomes of soil or sap evaluation, you may apply facet dressings of calcium nitrate alternated with potassium nitrate each two weeks from early operating. Apply each fertilizers at 20-40 kg/ha.
Apply magnesium sulphate on the price of 20 kg/ha after each 2-3 purposes of the calcium or potassium nitrate. Plant tissue evaluation can point out the crop’s nutrient standing all through the season.
Within the side of Dietary issues, Observe that Molybdenum deficiency is frequent in areas with a low pH. Signs embody stunting of plant progress and mottling, yellowing and rolling of leaves.
This deficiency might be remedied by a foliar spray of sodium molybdate on the 4 leaf stage, repeated if obligatory on the runner stage of progress. Zinc, copper and boron deficiencies may happen however are almost certainly in leached, strongly acidic, sandy soils or the place giant portions of liming supplies are current.
Therefore, zinc and boron deficiencies are additionally frequent on the alkaline soils of the Lockyer and Fassifern Valleys.
Manganese toxicity can be one other drawback related to acidic soils (pH 5.8 or much less). Seedlings affected by manganese toxicity exhibit stunted progress and yellowish crinkled leaves.
Older crops can have an unhealthy pale inexperienced solid, and affected crops could have pinhole-sized brown lesions occurring in clusters between the leaf veins.
These signs are sometimes confused with infectious illnesses, equivalent to gummy stem blight. You possibly can stop manganese toxicity by sustaining soil pH between 6.0 and 6.5.
7) Irrigation Elements
Water might be utilized to the crop by means of overhead, furrow, or drip irrigation. Drip irrigation allows essentially the most environment friendly use of obtainable water and is suitable with fertigation which is the appliance of soluble fertilizers within the irrigation water.
Relying on the time of the yr and the soil kind, the quantity of water used to develop a crop will range. In the meantime, the next figures can function a helpful information:
- When utilizing overhead sprinkler system= 4-5 ML/ha
- Utilizing furrow/flood= 4-5 ML/ha
- Utilizing Drip= 3 ML/ha.
Observe: Overwatering ought to be prevented when the crops are younger however portions ought to improve because the plant grows. The best water necessities are throughout fruit set and fruit fill. Water high quality is essential, notably if overhead irrigation is used.
Examine has proven that Electrical conductivity (EC) readings a lot better than 1.3-1.4 dS/m may trigger leaf burn and yield discount and with furrow or drip programs, irrigation water with EC readings as much as 2.0 dS/m can be utilized with care.
Past this determine, losses from a dysfunction often known as blossom finish rot could happen. Keep away from overhead irrigation at 7-11 am throughout flowering and fruit set, as this may increasingly deter bees from pollinating flowers.
8) Pollination Elements
Watermelons produce separate female and male flowers. Male flowers are produced initially, adopted by the manufacturing of each sexes normally at a ratio of 1 feminine to 7 males.
Watermelons, pumpkins, cucumbers and zucchinis might be planted facet by facet. Cross-pollination can happen between cultivars of the identical crop (e.g. watermelons and watermelons) however not between totally different crops (e.g. watermelons and pumpkins).
Bees are obligatory for pollination. Bees must be current and lively within the crop. If bees will not be plentiful, then import not less than 2 hives/ha, unfold them across the subject perimeter and test to make sure that male flowers are producing pollen.
Flowers are most receptive to pollination in the course of the morning hours when bee exercise is normally the best. Bee exercise is said to local weather and is decrease in cooler climate.
Spraying and irrigation ought to be coordinated to happen when bees are least lively and If potential, use chemical compounds with minimal bee toxicity.
