<p>Rice (<em>Oryza sativa </em>L.) is the most important and strategic food crop in Indonesia, but low productivity in tidal paddy fields is a serious problem that must be overcome. The application of ameliorant would be worthy to increase the growth and yield of rice in tidal paddy fields. The study aimed to investigate the effect of ameliorant application on growth and yield of rice varieties in tidal paddy fields. The study was arranged in a split plot design with five replications. Rice varieties tested were Inpari 34, Dendang, Inpara 9, Inpari 35, and Ciherang as the main plot, and ameliorant types studied were humic acid, gypsum, zeolite, and organic fertilizer as the subplot. The results showed that the use of different rice varieties and amelioran types significantly increased the growth and yield of rice. Inpara 9 produced 7.6 t.ha-1 dry milled grain (DMG) or increased by 33.3% compared to Ciherang variety. Humic acid application at 25 kg ha-1 increased grain yield by 21.3% higher than that without ameliorant treatment. The best treatment to increase the growth and yield of rice in tidal paddy field was a combination of humic acid 25 kg.ha-1 and Inpari 34 which produced the DMG of 8.6 t ha-1 or 41% higher compared to Ciherang without ameliorant.</p>

Dry direct seeded rice is an alternative to the farmers in the context of climate change and inputs scarcity especially labor. However, weeds are the major problem in dry direct seeded conditions competing with the different resources provided to the crop. Hence, field experiments were conducted for two consecutive years 2015 and 2016 in the experimental field of Rice Research Program, Hardinath, Dhanusha to identify the appropriate herbicides for DSR. The experiment was laid out in a split plot design and treatments were replicated thrice. Three varieties of rice namely Ciherang Sub-1, IET 16775 and Sukhkhadhan-3 were treated as main plot factors while five levels of weed control methods (Oxadiargyl @ 100 g a.i./ha as pre-emergence followed by Fenoxaprop @ 90 g a.i./ha with safener, Pendimethalin @ 1000 g a.i./ha as pre-emergence followed by Bispyribac sodium @ 25 g a.i/ha at three weeks after seeding, Pendimethalin @ 1000 g a.i./ha as pre-emergence followed by Pyrazosulfuron ethyl @ 25 g a.i.ha + Bispyribac sodium @ 25 g a.i./ha at three weeks after seeding, hand weeding and weedy check) were treated as sub-plot factors. The statistical analysis showed that the effect of weed control methods on yield and yield attributing parameters of the tested rice varieties was significant. Out of the tested treatments hand weeding yielded significantly higher grain yield (5.4 t/ha) followed by herbicides Pendimithalin fb Pyrazosulfuron ethyl + Bispyribac sodium; which reduced the weed density and was comparable with hand weeding. The interaction effect of weed control methods and varieties was found non-significant. Pendimithalin fb Pyrazosulfuron ethyl + Bispyribac sodium was found to control broad spectrum of weeds and also reduced the human labour drudgery and increasing the rice yield than the other herbicides in direct seeded rice.
