Abstract: The industrial quality of grain is an important parameter to determine the commercial value of rice and can be influenced by water availability and type of cultivar. The present study aimed to evaluate the milling yield as well as the protein and nutrient contents of polished grains originated from two upland rice cultivars grown under rainfed and sprinkler-irrigated conditions. A randomized block design was used in a split-plot arrangement with eight replicates. Plots consisted of two cropping systems (rainfe… Show more

“…Anthesis was delayed, the number of spikelets per panicle was reduced of 60% and when drought occurred during grain filling: The percentage of filled grains decreased of 40% (Boonjung and Fukai, 1996). Drought condition that cause lack of rain, specifically during the grain formation to ripening stages, it affects percentage of high chalky grain (15.20-17.50) and high broken grains (0.75-2.50%) of upland rice two varieties, it are an undesirable characteristic, since it decreases grain quality and economic value and also leads to a reduction of the milling yield (Crusciol et al, 2008).…”

“…However, the P accumulation (Figure 2 and Table 3) was not significant (p > 0.05) among treatments, showing that a lower P concentration was likely due to the "dilution" effect, which is confirmed by the higher shoot dry matter production observed for the 60 % CaSiO 3 treatment (Figure 1). For example, when plant production increases, the "dilution" effect for some nutrients can occur (Crusciol et al, 2008;Marschner, 1995;Miyauchi at al., 2008), which is the reduction of their concentration in the tissue without an alteration in the absorbed quantity. Still, the concentration of P in the plants cultivated on LVAd-1 and LVAd-2 were not different either among treatments.…”

“…Then, the soil was incubated for a period of 20 days, and the humidity was maintained between 70 and 80% of the maximum water retention capacity (CRUSCIOL et al, 2008 Each plot had a plastic pot with 4 kg of soil. Before sowing, nutrient solution containing all nutrients, except N, was applied, according to the recommendations suggested by Novais et al (1991) for conducting the experiments in a controlled environment.…”
