Grow bag farming: Things to remember to ensure good yield
As grow bag farming is a trend now, farmers have to be more careful about its drawbacks too. Cultivating same crop repeatedly can affect the yield. Even if the crop gave good yield in the first season, it is ideal to change the crop next time.
Planting long beans after any crop will help increase nitrogen content in the soil. Applying organic fertilisers is important for plant growth. Moist the soil in the grow bag two weeks before planting seeds and mix 50 grams of lime in it. Organic fertiliser can be added 10 days after this.
Vermicompost, dried cow dung powder or goat manure are good choices. Adding 1 kilogram of pseudomonas for 20 kilograms of organic fertilizer will protect the plants from fungal diseases. Mulching with quick stick leaves also is good for the plants.
Adding 50 grams of bone manure in the grow bag will boost growth of roots. The saplings of spinach, brinjal and green chilli that are replanted should be dipped in pseudomonas solution for 30 minutes before planting. Cow dung and rock phosphate can be applied as top fertilisers in grow bags.
After growing vegetables twice, the entire potting mix in the grow bag should be replaced. Soil solarisation will help reduce pest menaces and diseases. Drip irrigation method is most suitable for grow bag farming as it ensures accurate amount of water.
