To confirm your order a deposit of a minimum 50% of the total amount must be paid to begin production of your order.

A. Land Preparation

1. Clearing the land of grass/weeds and remaining plant roots, so that plant growth is not disturbed from pests and disease hosts
2. Plowing the soil and turning if with a tractor as deep as 30-40 cm to loosen the soil and improve soil drainage and aeration
3. Giving dolomite lime together with tillage if the soil pH < 5.5.
4. Making beds with a width of 110 cm height 20-25 cm according to the season, the width of the expanse of land for vines 200 cm width of the ditch 50-60 cm
5. Applying manure to the beds and stirring evenly until loose, needs 5 tons per hectare
6. Apply basic fertilizer UREA 50 kg, SP.36 100 kg, KCL 75 kg/Ha.
7. Covering the surface of the bed with soil from the trench until it is evenly distributed.

B. Planting

1. The need for spinach seeds per hectare is around 3000 to 3500 grams.
2. Water the beds before planting until they are evenly wet.
3. Make a planting groove across the surface of the bed with bamboo blades that are pointed at the ends as deep as 1.5-2 cm. The distance between the grooves is 15-20 cm. If for the purpose of harvesting seeds, make planting holes and use a spacing of 30 x 20 cm.
4. Plant the seeds in the grooves that have been made by spreading them thinly, at a density of 3-4 seeds per 1 cm of the groove length.
5. Cover the furrows with thin soil or rice husk mixture 0.5-1.0 cm thick.
6. Do regular watering with a fine sprinkling of Gembor/emrat.

C. Fertilization

1. Follow-up fertilization is carried out starting at the age of 10 HST with Pearl NPK fertilizer dissolved in 5 grams / liter of water
2. At the age of 15 DAP, apply fertilizer to the 2nd Urea 200 kg, and Kcl 75 kg per hectare by mixing the two fertilizers and sprinkling them in the grooves between the rows of plants.

D. Plant Maintenance

1. Thinning of plants
If the planting system in the grooves needs to be thinned if it grows too tightly, this should be done at the age of 15 HST before the 2nd follow-up fertilizer is carried out.
2. Weeding
Weeding is done so that there is no competition for nutrients in the soil between weeds and the main crop, do the weeding at the age of 10-15 HST. Before the 2nd follow-up fertilization.
3. Watering the Plants Watering the plants should be optimal because the age of the spinach plants is very short, around 25-30 HST. At the beginning before growing, do the watering in a Leb way or with a fine splash of water.

E. Disease Pests

1. Caterpillar destroyer of leaves (Plutella Xylostella)
Small light green caterpillar with a length of 7-10 cm. Attacking plant shoots. Chemical control with insecticides Decis 2.5 EC or Buldok 25 EC according to the instructions on the packaging.
2. Leaf Miner (Liriomyza sp.)
Leaf miner pest or leaf miner, its larvae attack the inner layers of the leaves and leave the skin of the leaves. Its control is with Trigard 75 WP insecticide.
3. Dumping Off Disease (Pythium sp.)
Attacking the base of the stems in young plants with blackish brown spots that cause the plants to fall and wilt. Control by spraying Previcur N as recommended.
4. Leaf Rot (Botrytis sp.)
Symptoms of attack are dark brown wet spots on leaves, irregular shape, Control with Kocide 60 WDG or Bion-M 1/48 WP Fungicide.

F. Harvesting

1. Harvest spinach aged 25-30 HST
2. Do watering the day before harvest to facilitate the removal of plants.
3. Uproot the plants by the roots in order to maintain the freshness of the plants.
4. Wash the plant roots and arrange them on open shelves in the wind so that the used washing water can drain.
5. Harvest yields are usually every 200 or 250 grams
