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

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.

Npk Fertilizer

<p>Non-organic agriculture has succeeded in increasing the production of lowland rice, but on the other hand also has a negative impact on the ecosystem of agriculture and the environment, such as the decreasing content of soil organic matter. One effort that can be done, is by adding bio-slurry organic fertilizer to the NPK fertilizer. This study was conducted to determine the effect of the combination of bio-slurry fertilizer and NPK fertilizer on the production of four rice paddy varieties. This research by experiment was conducted in Screen House Agrotechnopark, Faculty of Animal Husbandry and Agriculture, Diponegoro University, Tembalang Semarang campus, taking place from October 2018 to January 2019. The experiment used a randomized completely block design with two factors and three replications. The first factor was a combination of bio-slurry + NPK fertilizer ie without N (P0) fertilizer, NPK 550 kg ha<sup>-1</sup> fertilizer (P1), bio-slurry fertilizer 3 tons ha<sup>-1</sup> + NPK fertilizer 400 kg ha<sup>-1</sup> , 6 tons ha<sup>-1</sup> bio-slurry fertilizer + 250 kg ha<sup>-1</sup> NPK fertilizer, 9 tons ha<sup>-1</sup> bio-slurry fertilizer + 100 kg ha<sup>-1</sup> NPK fertilizer and 12 tons bio-slurry fertilizer ha<sup>-1</sup>. Whereas the second factor was the lowland rice varieties namely Inpari 23, Sultan Unsrat, Sintanur and Gilirang. The results of the variance analysis showed that the combination of bio-slurry + NPK fertilizer and lowland rice varieties had a very significant effect on grain yield per clump, number of filled grains, number of empty grains, total grain count, weight of 1000 grains, rice yield per pot and harvest index. The highest grain yield per clump (85.33 g) was obtained from the treatment of 550 kg ha<sup>-1</sup> NPK fertilizer, while the highest grain yield per clump (58.06 g) was obtained from the Gilirang variety (V4), the highest total grain amount (174.58 grains) was obtained from the treatment of NPK 550 kg ha<sup>-1</sup> and (212.28 grains) fertilizer produced by varieties Inpari 23. The highest yield per pot of rice (61.83 g) was obtained from the treatment of 550 kg ha<sup>-1</sup> NPK fertilizer , while the highest paddy rice varieties which produced rice per pot of (63.22 g) were Inpari 23.</p>
