“…In addition, the lack of puddling during land preparation means that percolation losses will be larger during crop growth. Bhuiyan et al (1995) reported that direct seeding reduced water input at a site in the Philippines because of substantial water savings during land preparation. Cabangon et al (2002) also found that direct seeding reduced water inputs compared to transplanting in the Muda Irrigation System in Malaysia.…”

“…Comparing with transplanting, rice direct seeding saves water [14][15][16][17][18][19] and reduces greenhouse gas (GHG) emissions [20][21][22][23] . Therefore, rice direct seeding mechanization is one of the most simple, effective, and sustainable ways to cope with labour shortages and high production costs [24][25][26][27][28][29][30][31][32] .…”

Mechanized rice direct seeding is a cost-effective and efficient approach for rice cultivation. Recently, the use of rice direct seeding has been increasing rapidly owing to rural labour shortages and continuous increases in agricultural production costs. This article reviews the research and application progress of mechanized rice direct seeding including direct seeding technologies, precision rice seeding, precision rice seed-metering devices, key supporting agronomy technologies for mechanized rice direct seeding. South China Agricultural University developed precision rice hill-drop drilling (PRHDD) with synchronous furrowing and ridging technology and series machines for paddy that affords remarkable advantages in terms of saving time and labour, higher yield, and higher efficiency. In this approach, pre-germinated seeds are uniformly hill-dropped in the expected positions in puddled soil. It significantly improved the crop growth population and effectively solved the problems of high frequency of disease and pests caused by the irregular distribution of rice seeds with manual broadcasting, and generally reduces seed usage and increases the yield. Therefore, this technology has broad application prospects and great potential for promoting the development of mechanized rice direct seeding in China.

“…Direct seeding, one stand establishment technique used in rice, is of interest as a means of reducing cost of production due to less labor requirement (Erguisa et al 1990), shorter rice crop duration (Bangun and Effendi 1993), and more efficient water use (Bhuiyan et al 1995). Although direct seeding has advantages compared to transplanting system, some constraints need to be addressed.…”

Direct seeding has some advantages compared to transplanting system in rice, however there are some constraints need to be addressed. One constraint generally faced in the wet seeded rice is poor stand establishment. The experiment was conducted to improve seedling establishment by using selected growth regulators. Seeds of four rice cultivars, i.e. Memberamo, Widas, MR 84, and MR 219 were treated with GA 3 (gibberellic acid-3) of 25, 50, and 100 mg 1 -1 , and IBA (indole-3 butyric acid) of 10, 20, and 40 mg l -1 . Results showed that cultivar response to GA 3 was similar in all parameters observed, however the response of cultivars to IBA was different at the initial stage. In Indonesian cultivars (Memberamo and Widas), shoot length of IBA treated seedlings was comparable to the control, but the IBA treated seedlings of Malaysian cultivars (MR 84 and MR 219) had slightly shorter shoots compared to the control. GA 3 as seed treatment induced favorable early emergence and shoot growth in the initial stage, but the shoots were etiolated and resulted in susceptible to lodging even in the vegetative stage. In comparison, exogenous application of IBA resulted in high number of adventitious roots contributing towards better establishment of seedling with broader and greener leaves. The growth regulator was lost its effect by 2 or 3 weeks after sowing. All IBA concentrations also did not show any significant differences on growth parameters or have any detrimental effect on grain yield in all cultivar tested. IBA 10 mg l -1 was sufficient in providing the required improvement in the rice seedlings.
