<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>

The Village

This research aims to determine the performance of new varieties of farm (VUB), lowland rice through an integrated approach to crop management (ICM) in the village of Gle Aneuk Indrapuri, Aceh Besar District. Field assessment is from cooperative farmers who have lowland rice varieties with treatment, such as Cimelati, Bondoyudo, Ciherang, Kalimas, VUTB Fatmawati and IR-64. In each of these rice varieties applied packages introduced PTT technology. The result indicates that reviewed the six varieties suitable for cultivated and developed. Judging from the performance of agronomic VUTB Fatmawati better compared with 5 other varieties. VUTB Fatmawati have the greatest production (7.75 tonnes / ha) with a profit-making Rp.6.074.750, -. Fatmawati lowland rice farming system with ICM pattern is more feasible to be developed because the RC has the largest ratio (2.09) compared with the varieties Cimelati (2,06), Kalimas (2,04), Bondoyudo (2,02), Ciherang (1,51) and varieties of IR-164 (1,39).Key words: farming, rice, varieties, integrated crop management

Derived Savanna

This investigation tested the hypothesis that the alternate wet and dry (AWD) water regime would increase soil microbial biomass carbon (MBC), microbial biomass nitrogen (MBN) and microbial count. Variations in MBC, MBN and grain yield could be due to varietal differences in a derived savanna. Experiments (both pot and field ones) were conducted at the Federal University of Agriculture, Abeokuta (Latitude 7? 12? to 7? 20? N and Longitude 3? 20? to 3? 28? E), Nigeria in 2015. In both trials, the treatments consisted of water regimes (continuous flooding [control] and AWD imposed on lowland rice varieties [NERICA?L-19])and Ofada [local check] at the vegetative growth stage in three cycles. The design in both trials was a completely randomised and randomised complete block design for the pot and field experiments respectively, with three replicates. In the screen house, MBC and MBN were significantly higher in AWD than in continuously flooded soil, especially at the beginning of the AWD cycles. This could have caused nutrient pulses to sustain the improved performance of lowland rice under AWD. A converse pattern was observed in the field in the third cycle. Ofada rice had a significantly higher microbial count and MBC (cycle 1) than NERICA L-19, however, a converse pattern was observed in MBC (cycles 2 and 3) and MBN (cycle 1). Composition of their rhizodeposition and timing of cycles could explain the observed varietal differences in MBC and MBN.
