“…Previous studies [52,53] also stated that higher amounts of straw incorporation affected the emergence rate of the rice crop and the growth quality at the seedling stage. These findings are also supported by prior research [23,28,54], which concluded that higher rice grain yields were produced by the balanced input of residue with RT methods compared to the control or other nutrient management practices.…”

Soil management practices are used to enhance soil organic carbon, fertility, and crop productivity around the world. However, accurate information about the appropriate amount of straw incorporation is not available, because it is generally believed that at least 30% of the soil surface should be covered by straw, which is not implemented in all field environments. Therefore, a two-year (2016-2017) field experiment was conducted to investigate the impact of different percentages of straw incorporation and tillage methods, i.e., reduced tillage (RT) and conventional tillage (CT), on crop yield, soil organic carbon (SOC), total nitrogen (TN), and soil carbon storage (SCS) in rice-wheat cropping systems, under eight treatments. The experimental results showed that the greatest reduction in soil dry bulk density (ρ b ) was found under CT with 100% straw coverage (9.79%), whereas the least reduction occurred under CT with no straw (1.31%). The mean TN concentration, soil organic matter (SOM), and soil carbon storage (SCS) were significantly higher by 0.98 g/kg, 17.07%, and 14.20%, respectively, under reduced tillage with 60% straw incorporation (RTsi 60 ) compared with all other treatments. Our findings demonstrate that the incorporated wheat residues resulted in the highest rice production (7.95-8.63 t/ha) under RTsi 60 . We recommend the adoption of reduced tillage with 60% straw incorporation to increase rice yield, improve soil structure, and enhance TN, SOM, and SCS in paddy soil under rice-wheat rotation fields for agricultural sustainability.

“…Beberapa hasil penelitian yang dilaporkan Bayer et al (2014); Zhang et al (2015); dan Champbell et al (2013) menyimpulkan bahwa penerapan teknologi tanpa olah tanah, baik itu untuk budidaya padi sawah ataupun tanaman lainnya, akan mengurangi kehilangan karbon sehingga emisi karbon yang dihasilkan cenderung lebih kecil, tetapi akan meningkatkan emisi denitrogen oksida (N2O) karena adanya peningkatan kompetisi aktivitas mikroba dalam mendapatkan oksigen. Di luar negeri, bahkan juga oleh FAO, sekarang ini sedang banyak dikembangkan apa yang disebut dengan conservation agriculture, yaitu cara bercocok tanam dengan meminimalkan gangguan pada tanah atau dikenal juga dengan istilah No tillage/Zero Tillage (tanpa olah tanah).…”

“…Hal sempurna mengemisi N2O lebih rendah dibandingkan teknologi tanpa olah tanah (Gambar 7). Sistem olah tanah menyebabkan rongga tanah akan lebih lebar, sehingga oksigen dalam tanah menjadi lebih banyak tersedia, dimana hal ini akan menyebabkan kompetisi mikroorganisme dalam mendapatkan oksigen menjadi lebih kecil (Zhang et al, 2015;Bayer et al, 2014). Berdasarkan hasil perhitungan global warming potential atau potensi pemanasan global, teknologi tanpa olah tanah secara keseluruhan menghasilkan nilai GWP sebesar 6,1 t CO2e/ha/musim, lebih rendah dibandingkan teknologi olah tanah sempurna yang menghasilkan 7,3 t CO2e/ha/musim.…”

ABSTRAKTanpa olah tanah (NT) telah banyak ditunjukkan sebagai praktik pengelolaan lahan sawah yang mampu mengurangi emisi gas rumah kaca (GRK) karena kemampuannya untuk menyerap karbon dalam tanah. Di luar negeri, bahkan juga oleh FAO, sekarang ini sedang banyak dikembangkan apa yang disebut dengan conservation agriculture, yaitu cara bercocok tanam dengan meminimalkan gangguan pada tanah atau dikenal juga dengan istilah No tillage/Zero Tillage (tanpa olah tanah). Penelitian ini bertujuan untuk memperoleh informasi emisi CH4 dan N2O dari lahan sawah di daerah tropis dengan perlakuan cara olah tanah. Percobaan disusun dengan rancangan faktorial acak kelompok 3 ulangan. Perlakuan yang dicobakan terdiri dari 2 faktor, yaitu faktor I cara olah tanah (1) Olah tanah sempurna, (2) tanpa olah tanah, dan faktor II adalah pemberian herbisida berupa (1) glifosat, (2) paraquat dan (3) tanpa herbisida. Jarak tanam adalah tegel 20 cm x 20 cm. Emisi CH4 pada MK 2015 yang terendah adalah pada perlakuan tanpa olah tanah (TOT) dan pemberian herbisida glifosat, yaitu sebesar 201 kg CH4/ha/musim dan yang tertinggi pada perlakuan olah tanah sempurna tanpa penambahan herbisida yaitu sebesar 353 kg CH4/ha/musim. Tanpa olah tanah menghasilkan rerata fluks harian CH4 yang lebih rendah dibanding perlakuan olah tanah sempurna. Emisi N2O terendah dihasilkan pada perlakuan olah tanah sempurna dengan penambahan herbisida glifosat, yaitu sebesar 0,34 kg N2O/ha/musim, dan tertinggi pada perlakuan tanpa olah tanah dengan penambahan herbisida paraquat yaitu sebesar 0,65 kg N2O/ha/musim. Hasil padi pada semua perlakuan menunjukkan nilai yang tidak berbeda nyata. Faktor emisi N2O langsung dari lahan padi sawah irigasi dengan perlakuan olah tanah dan herbisida berkisar antara 0,0008 -0,0015 kg N2O-N/kg N dengan kisaran hasil padi sebesar 4,96 -5,12 t/ha GKG. Secara total, yang dinyatakan dengan GWP, perlakuan tanpa olah tanah menimbulkan emisi GRK yang lebih kecil dibanding perlakuan olah tanah sempurna Kata kunci: olah tanah, herbisida, GWP, CH4, N2O ABSTRACTNo-tillage (NT) management has been promoted as a practice capable of offsetting greenhouse gas (GHG) emissions because of its ability to sequester carbon in soils. Even FAO and many countries, are now being widely developed what so called conservation agriculture, on how to grow crops with minimize soil disturbance or also known as No tillage/Zero tillage. This study aimed to obtain information CH4 and N2O emissions and grain yield from rice fields in the tropics with tillage treatments. The experiment was arranged in a randomized factorial design with 3 replications. The treatments tested consisted of two factors, namely the first factor was tillage (1) deep tillage, (2) zero tillage, and the second factor is application of herbicide in the form of (1) glyphosate, (2) paraquat and (3) without herbicides, using tiles row spacing (20 x 20 cm). In DS 2015, the lowest CH4 emissions resulted from no-tillage (TOT) treatment combined with the application of glyphosate, which amounted to 201 kg CH4/...

Adopting suitable tillage and fertilization technologies for wheat (Triticum aestivum L.) can address poor soil conditions and high residual nitrogen following rice (Oryza sativa L.) harvest to improve the sustainability of rice-wheat rotation systems. A field experiment was conducted in 2016-2018 to investigate the influence of tillage methods and nitrogen rates on wheat seedling growth (at the beginning of over-wintering stage), tillering characteristics, and grain yield. The tillage methods included notillage (NT), rotary tillage twice (RR), and plow tillage followed by rotary tillage (PR). The nitrogen rates were 270 (N270), 240 (N240), and 210 kg ha −1 (N210).In 2016-2017 (higher soil moisture during tillage), NT improved early growth (i.e., leaf area and biomass per stem), single spike yield, and grain yield compared with PR and RR. In 2017-2018 (lower soil moisture during tillage), PR and RR resulted in stronger seedlings (greater tiller number and leaf area and biomass per stem), more fertile tillers, and higher grain yield than NT. In both years, grain yield under RR was between that of PR and NT. With reduced nitrogen application, seedling growth, tiller number, single spike yield, and grain yield showed a declining tendency. We found that more tillers at seedling growth stage (the five-leaf stage in both years) could boost fertile tiller number, and at this time greater leaf area and biomass per stem were correlated with higher single spike yield. This study demonstrates that suitable tillage and fertilizer applications can facilitate yield formation through improved number and vigor of the early-produced tillers.
