| Summary: | Environmental stress factors such as limited water occur all over the world
including in Malaysia. Generally, grain filling will reduce when limited water supply
or drought was imposed during reproductive stages of rice cultivation throughout
over the world. An experiment was conducted to select the best foliar fertilizer that
can increase grain filling of rice under limited water supply. The variety of rice
cultivated was MR219 by using pot. There were 36 totals of pots with three hills of
paddy plant per pot. Six treatments were applied to the paddy; normal flooding,
cyclic water stress for six days, cyclic water stress for six days + spermine, cyclic
water stress for six days + silica, cyclic water stress for six days + brassinolide, and
cyclic water stress for six days + multiple-compound fertilizer mixed with humic
acid. Each treatment had six replications. Growth parameters were taken in range
five to ten days after the treatment was applied. In yield attributes, the filled grain per
hill, thousand grain weight, and etc was taken after harvesting. The experiment was
conducted at Rice Research Centre, Greenhouse B at Ladang 10, UPM Serdang,
Selangor. The treatments were laid out in a Randomize Complete Block Design
(RCBD) and data obtained were analyzed using analysis of variance (ANOVA) with
The Statistical Analysis System (SAS) software. The objective of this experiment
was to find the best foliar fertilizer that can improve grain filling and yield of rice
under limited water supply. All foliar fertilizer that has been applied to paddy plant
showed positive impact on grain filling of paddy plant. The best foliar fertilizer that
can be applied by farmers to overcome drought or water stress condition was
spermine (2.06 ton haˉ¹). |
