    Validation of water use efficiency of irrigated lowland rice during early and normal cropping calendar with varying nitrogen levels (2019 DS) [manuscript]
    (2019) Vincent Ralf A. Alivia
    Water is one of the most important resources in the crop production mostly in irrigated lowland rice. Water scarcity is due to the climate change and increasing competition among the household, industry and intimidates the efficiency of irrigated lowland rice because of its high water requirement. The study was conducted from November 2018 to March 2019 at the Crop Science Experimental Area, College of Agriculture, Central Luzon State University, Science City of Muñoz, Nueva Ecija. This study was showed to evaluate the water use (ET) anf water use efficiency (WUE) of early and normal planting of dry season of rice with varying Nitrogen levels. This study of two factors field experiment was carried out in Nueva Ecija during 2019 of dry season of rice cropping using Split-plot design with planting date (November and December 2018) as main-plot and Nitrogen level (0,81,90,120 kg N ha-1) as sub-plot with three replications. Plot size was 20m2 with three pails each to measure water use (ET. Results of this study showed that Nitrogen with the highest amount of level of application which is 120 kg ha-1 had the highest plant height, it can yield more grains and increase the number of tillers. In the field conditions the application of nitrogen fertilizer is the most common and effective way to enhance the tiller population. Here, it can be concluded that in EP there was a lower water use that would allow less consumption of water irrigation while NP had higher water use but then it can yield higher grain yield. The findings of this study suggest the possibility of adjusting planting date to early planting of dry season for a lower water requirement without consequences in the yield but it may lower in terms of WUE than NP. Another set of experiment will be conducted to verify the results.
