Rice is an important food crop in Indonesia. This condition encourages the need to increase national rice production. Increased national rice productivity is also needed to reduce rice imports and achieve resilience and self-sufficiency. The effort to increase national rice production is Salibu rice cultivation. This study uses a split- split plot design with an area plot of 1m x 1m, whereas the main plot is the organic rice booster formula from the stem trimmed 15 cm (B) and the stem trimmed 30 cm (N). Organic cow manure (B1), organic goat manure (B2), chicken organic manure (B3) and not given (NB) as subplots while three rice varieties, Ciherang, Mekongga and Inpara as subplots.. The parameters observed for the potential of each production variety in each plot of all treatments (ton/ha) included the number and weight of grain and rice growth including plant height, panicle length, and some tillers. From the results of preliminary research that the weight production of plotted grain has a very significant effect on the V2 Cavity Variety (213.46). For V3 Veritas V3 has a genuine effect on V2 Vascularity. Parameters of Grain Weight Perplot after statistical tests showed that the treatment of Chiherang V1 variety (870.63 gr) had no significant effect on Variety V3 (872.08 gr), but it was the very significant effect on Void Cavity V2 (901.63 g). For V3, it has a genuine effect on V2 Vascularity.

<p>In the middle of 1980s, rice self-sufficiency in Indonesia has been achieved, but the growth of rice production slowed down since the 1990s. Narrow genetic variability of released rice varieties contributed largely to the occurrence of leveling of potential rice yield over the past decades. To enlarge the genetic variability, an intersubspecies crossing of Koshihikari (japonica) and IR36 (indica) has been performed. Through this crossing, three high yielding and high yield quality promising lines of KI 37, KI 238, and KI 730 have been obtained. The objective of this study was to evaluate the superiorities of these lines through multi-location yield trials, pests, diseases, and grain qualities examinations. Examination methods used followed the release food crops variety procedure issued by the Indonesian Ministry of Agriculture. The result of examinations showed that the average yield of KI 730 was 7.47 t/ha, it was significantly higher than that of Ciherang (6,73 t/ha). KI 730 has a good grain quality, with translucent milled rice, a high percentage of milled rice (78.0%) and head rice (91.01%). The texture of its cooking rice was soft, sticky, with the amylose content of 20.41%. In addition, pests and diseases resistances of KI 730 were better than those of other lines tested. After evaluation by National Food Crops Release Variety Team, the KI 730 line was released as a national superior variety with the name of Tropiko. Tropiko should become an alternative variety to grow widely in order to increase national rice production and farmers income.</p>

Rice is one of the important food crops, feeding more than 50% of the global population. The climate change is adversely affecting the rice production across the rice growing regions. The major challenges posing threat to the world rice production are various biotic and abiotic stresses. Rice is grown and consumed largely by the developing countries, and most part of the population in these regions are undernourished with unbalanced and comparatively low nutritional food. Therefore, it is of utmost importance to develop rice varieties for higher nutritional value with attributes for better adaptability to various stresses. In the present review, we have discussed about the different CRISPR/Cas genome editing tools, and their applications for biotic and abiotic stress tolerance, yield and also for grain and nutritional quality improvement in rice.
