Mulching is an agricultural cropping technique that involves placing organic or synthetic materials on the soil around plants to provide a more favorable environment for growth and production.

Plastic mulches have been used by commercial growers since the early 1960s, with black and clear plastics being the most popular. Tomatoes, peppers, eggplants, vine crops and okra generally respond well to these plastics. Plastic mulches normally are used in conjunction with Drip Irrigation to maintain optimum soil moisture and for improved stand establishment

Plastic mulch raises the soil temperature in the planting bed which promotes faster crop development and earlier yields. Black plastic mulch with perfect contact with soil can result in 2 to 7 days earlier harvest while Al-OR sun selector mulch can result in a 10-14 day earlier harvest.


  • Earlier yields-> Plastic mulch acts to raise soil temperature, thereby promoting faster crop development and earlier yields.
  • Weed control-> Back and White on Black mulches reduces light penetration to the soil. Weeds generally cannot survive under the mulch.
  • Reduced evaporation->Soil water loss is reduced under plastic mulch.
  • Aids fumigation-> Mulch increases the effectiveness of soil fumigant chemicals. Because of the impervious nature of the plastic mulch, it acts as a barrier to gas escape.
  • Reduced fertilizer leaching-> Excess water runs off the impervious mulch. Fertilizer beneath the mulch is not lost to leaching, so fertilizers are efficiently used and not wasted.
  • Cleaner product->The edible product from a mulched crop is cleaner and less subject to rot because soil is not splashed on the plants or the fruit.

Mulching with Drip Irrigation for vegetable cultivation  - 1 acre:

  • After the raised beds are ready with the drip irrigation in line , soil has to be removed up to half feet on both sides of the bed and then the film has to be laid.
  • The film has to be laid based on the wind direction
  • Once the mulch is fixed on the beds with the pressure of the soil, holes are made depending on the planting space.
  • The size of the hole must be made keeping in mind that the plant does not touch the mulch.
