Abstract:

Transplanting of rice seedlings is an age-old practice. In recent years, the migration of labor to the industrial sector, especially in India, has led to the nonavailability of labor for transplanting at the appropriate time, resulting in a yield reduction. This method of stand establishment is also laborious and time-consuming and results in drudgery among women workers. Cultivation practices, such as nursery preparation and management, fertilizer and pesticide application and irrigation to the nursery, pulling out seedlings, and transplanting in the main field, account for the major share of cultivation costs. Hence, an alternative method had to be found to overcome problems encountered in using the transplanting technique. Direct seeding and throwing of seedlings under puddled conditions are viable alternatives to transplanting. Matsushima (1980) cited the advantages of throwing seedlings over a puddled field instead of transplanting. Hence, a study was conducted to evaluate the feasibility of different stand establishment techniques in lowland irrigated rice during the 1999 wet season (Aug-Dec) and 2000 dry season (Feb-May).
