Mechanized System of Rice Intensification


The Modified System of Rice Intensification (MSRI) is transforming paddy growing, guaranteeing greater yields with less resources. This approach, an adjustment of the System of Rice Intensification (SRI), enhances plant spacing, water use, and soil fertility. Research studies show that MSRI can increase yields by as much as 50-55% while decreasing water use by 30%.

MSRI in Paddy

This technique is especially in India, where rice is a staple crop, and water shortage is a growing issue. MSRI’s prospective to boost food security and farmers’ incomes makes it a vital advancement in sustainable farming.

Introduction to Mechanized System Rice Intensification (MSRI)

The Mechanized System of Rice Intensification (MSRI) is a technique of rice growing that integrates the concepts of the System of Rice Intensification with using makers for transplanting, weeding, and harvesting. MSRI intends to increase rice yield and minimize water, labor, and seed requirements while lessening ecological effects.

The Mechanized System of Rice Intensification (MSRI) innovation in the Visakhapatnam district of Andhra Pradesh, India, has actually led to a 20.76% yield boost over the typical transplanting approach. This has actually caused an extra earnings of Rs. 15038 for farmers. The advantages of MSRI consist of lowered manual work per ha and increased yield characteristics like tillers, panicles, grains, and test weight. MSRI includes:

  • Transplanting 20-day-old seedlings in square planting at 20 cm × 20 cm spacing with 2 seedlings hill − 1.
  • Using a mechanical transplanter.
  • Cono-weeder.
  • Reaper.

This method can boost rice efficiency and success while conserving water and labor resources. It appropriates for locations with limited labor or restricted watering water and is budget friendly and practical. MSRI can likewise add to environment modification mitigation and adjustment by decreasing greenhouse gas emissions and increasing durability to dry spell and flood.

Solution: Extension services, presentation plots, farmer-to-farmer knowing, mass media can be utilized to distribute info and understanding about MSRI to paddy farmers. Success stories and reviews from other farmers who have actually embraced MSRI can likewise be shared to encourage and persuade them.

Lack of schedule: Many paddy farmers require access to the makers and devices needed for MSRI, such as weeders, harvesters, and transplanters. They might likewise require assistance in obtaining quality fertilizers, pesticides, and seeds.

Solution: Public-private collaborations, cooperatives, self-help groups, and farmer companies can be formed to assist in the schedule and cost of the makers and inputs for MSRI. The federal government and other companies can likewise offer aids, loans, insurance coverage, and rewards to support the paddy farmers in embracing MSRI.

Lack of abilities: Many paddy farmers require to acquire the abilities and understanding to run and preserve the makers and devices for MSRI. They might likewise deal with difficulties in getting used to the brand-new practices and methods associated with MSRI.

Solution: Training programs, workshops, field gos to, and handbooks can be arranged to impart the abilities and understanding to the paddy farmers on how to utilize and handle the makers and devices for MSRI. Specialists and extension employees can likewise offer technical help and feedback to assist them get rid of any issues or troubles they might experience in executing MSRI.

Mechanized System Rice Intensification Equipment and Technology

  • Transplanter: A maker that transplants young seedlings from nursery trays to ready fields at a consistent depth and spacing. It can cover 0.5-1 ha daily with a fuel usage of 5-10 liters per ha.
  • Weeder: A maker that gets rid of weeds from the fields by turning branches or blades. It can cover 0.5-1 ha daily with a fuel usage of 3-5 liters per ha.
  • Harvester: A maker that cuts, threshes, and cleans up the rice crop from the fields. It can cover 1-2 ha daily with a fuel usage of 15-20 liters per ha.
  • Seed drill: A maker that plants seeds straight into the fields without transplanting. It can cover 0.5-1 ha daily with a fuel usage of 5-10 liters per ha.
  • Laser land leveler: A maker that levels the fields utilizing a laser beam and a scraper. It can enhance water utilize effectiveness, harmony of crop development, and weed control.

Best Practices for Implementing MSRI

  • Select quality seeds of stress-tolerant and high-yielding ranges ideal for agro-climatic conditions and customer choices.
  • Prepare nursery beds with fertile and well-drained soil, and plant seeds at a rate of 1-2 kg/100 m2. Cover the seeds with a layer of soil and mulch, and water them routinely.
  • Prepare fields with appropriate plowing, painful, leveling, and puddling. Apply natural manure or garden compost at a rate of 5-10 t/ha before raking.
