Direct seeding:
Direct-seeded crops require less labor and tend to mature faster than transplanted crops. In this method, plants are not subject to stress such as pulling from the soil and regrowing fine roots. However, they have more competition from weeds.
Resilient practice:
Researchers have developed a direct-seeding alternative suitable for transplanting rice. In direct-directed rice (DSR) cultivation, there is no need to develop a nursery for transplantation. Farmers can avoid the main problem facing Punjab, the shortage of transplanting labor due to peak demand.
In the event of a delayed monsoon or lack of water, DSR gives farmers the flexibility to directly sow paddy with varieties of the right duration to suit the remainder of the season. This allows for timely sowing of subsequent rabi wheat. Compared with transplanting flooded rice, direct sowing rice consumes relatively less water.
Pumping water for irrigation also requires less energy than transplanting rice, and the energy savings can be much higher in the event of insufficient rainfall. Rough and basmati rice can be grown by direct seeding where feasible in the IGP Northwest Territories.
Impact of direct seeded rice:
Gurpreet Singh of Pindi Blochan Village, Faridkot District, Punjab, operates a rice and wheat planting system on approximately 32 acres (12 acres of own land and 20 acres of leased land). At first, due to the rain, he was unable to live stream the rough rice.
For the first time, he is direct seeding basmati rice on 5 acres and traditional transplanted rice on another 15 acres. The average yield of direct sown basmati rice was 51 q/ha, while the average yield of transplanted coarse rice was 46.3 q/ha.
Through DSR, he saved about Rs 3000-4000 per hectare in labor cost and irrigation water (7 irrigations less). However, he had to spend on herbicide applications. In the 2013-14 season, he doubled the acreage of live basmati rice.
Rice direct seeding: Experiences:
Rice is one of the most important food crops in the world and is the staple food for more than half of the world's population. The looming water crisis, the water-intensive nature of rice farming, and rising labor costs have driven the search for alternative management methods to increase water productivity in rice farming.
Direct-directed rice (DSR) has received much attention due to its low input demand. It involves sowing pre-germinated seeds onto the soil surface of a puddle (wet sowing), standing water (water sowing) or dry sowing into a prepared seedbed (dry sowing). In Europe, Australia and the United States, DSRs are highly mechanized.
The development of early-maturing varieties and the increase in improved nutrient management techniques and chemical weed control methods have encouraged many farmers in the Philippines, Malaysia, Thailand and India to switch from transplanting to DSR cultivation.
This transition will substantially reduce crop water requirements, soil organic matter turnover, nutrient relationships, carbon sequestration, weed biota and greenhouse gas emissions. Nonetheless, weed infestation can cause substantial yield losses in DSR.
In addition, recent occurrences of rice blast, crop lodging, impaired grain quality and stagnant yields over the years are major challenges in this regard. In this review, we discuss experiences, potential advantages, and issues related to DSR, and propose possible future patterns of change in rice cultivation.
