Abstract:
The objective of this study was to evaluate the effects of land preparation methods and iron-coated (Fe-coated) rice seeds on the growth, yield, and Fe uptake of rice in alluvial soils in the Mekong Delta region. The experiment was conducted in the 2020 summer-autumn cropping season under the triple rice cultivation system in Chau Thanh district, An Giang province. The field experiment was designed as a randomized complete block design (RCBD) with six treatments and four replications. The treatments were: (T1) puddled + water seeding + Fe-coated seeds; (T2) non-puddled + dry seeding + Fe-coated seeds; (T3) zero-tillage + non-puddled + dry seeding + Fe-coated seeds; (T4) puddled + water seeding + sprouted + non-Fe-coated seeds; (T5) puddled + wet seeding + sprouted + non-Fe-coated seeds; and (T6) puddled + transplanting + sprouted + non-Fe-coated seeds. The results showed that changes in the land preparation, planting method, and Fe-coated seeds did not significantly affect the number of tillers, plant height, yield components, soil chemical properties, grain yield, or Fe uptake of the rice plants and grains. However, the T3 and T6 treatments tended to have higher grains yields (5.86-5.90 tons ha-1), and higher total Fe content in grains (93.0-94.3 mg kg-1) and rice plants (83.1-84.0 mg kg-1). The findings from this study confirmed that the new planting method using zero-tillage + non-puddled + dry seeding + Fe-coated seeds can maintain the germination rate, growth, and grain yield of rice.

Abstract:
The field experiment was carried out at Regional Research and Technology Transfer Station, Bhawanipatna, Kalahandi under Odisha University of Agriculture and Technology, Bhubaneswar to assess the performance of the different crop establishment methods and age of seedlings on productivity and profitability of rice under rice-pea paira cropping system during 2019-20 and 2020-21. The experiment comprised of three crop establishment methods i.e. mechanical transplanting in puddled soil (MTP), mechanical transplanting in non-puddled soil (MTNP) and manual line transplanting in puddled soil (TP) in main plots and four age of seedlings viz., 14,17,20 and 23 days in sub-plots laid out in split-plot design with three replications. Chickpea was sown as paira crop 15 days prior to the harvest of paddy. The rice equivalent yield (REY) of 7143 kg ha-1 and gross return, net return and return rupee-1 invested was maximum in MTNP with younger seedlings of 14 days old. Among crop establishment methods, higher REY was obtained in mechanical transplanting in non-puddled soil (6486 kg ha-1) which was at par with mechanical transplanting in puddled soil (6448kg ha-1) and better than manual transplanting in puddled soil (5753 kg ha-1) method. Among the four age of seedlings, REY was higher in 14 days old seedlings (6766 kg ha-1) which was at par with 17 days seedlings (4753 kg ha-1) but significantly different from 20 days old seedlings (6030 kg ha-1) and 23 days old seedlings (5645 kgha-1). Net return and return rupee-1 invested were higher in mechanical transplanting in non-puddled soil (Rs.68575 ha-1 and 2.45) which was at par with mechanical transplanting in puddled soil (Rs.66137 ha-1 and 2.35).

Abstract:
Field experiments were conducted with two tillage practices in rice (Puddled and Non- puddled) during rainy season and three seed priming methods (Bio- seed priming with Rhizobium, hydropriming and no seed priming) and two foliar spray (2% DAP and 2% urea) during post rainy seasons in blackgram. The results indicated that the soil penetration resistance was found to be lesser in the soils of non-puddled tillage. The rice yield reduction due to NPTR was non-significant (less than 3 per cent). However, the soil penetration resistance was higher with the soils of blackgram sown as succeeding crop in the PTR. The blackgram yield obtained under NPTR was 10.6 per cent higher than PTR system. Bio seed priming with Rhizobium increased the yield by 26.0 per cent over no seed priming. The study indicated that NPTR showed a positive impact on the yield in the rice-blackgram relay cropping system. Bangladesh J. Bot. 53(3): 519-525, 2024 (September)

Abstract:
A field study was carried out during rabi (winter) seasons of 2018–19 and 2019–20 at Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai, Tamil Nadu to study the effect of four different crop establishment methods, viz. manual transplanting; transplanting of rice seedling in puddled soil using machine; transplanting of rice seedling in non-puddled soil using machine; and direct sowing combined with four different irrigation treatments, viz. farmers practice; irrigation following the development of a hairline crack; irrigation when water level descents 5 cm; and 10 cm below soil surface on physiology of rice (Oryza sativa L.). Experiment was conducted in a strip plot design replicated thrice. The study revealed that nutrient uptake and physiological parameters were found to be maximum with seedlings of rice crop transplanted in non-puddled soil using machine combined with irrigation following the development of a hairline crack. Seedlings of rice crop transplanted in non-puddled soil using machine combined with irrigation once the water level descends to 5 cm beneath the soil surface, had a significant positive influence on rice yield during both the years. It also recorded higher photosynthetic rate and improved physiological parameters, and yield even with minimum use of water. So, it may be recommended as the best alternate method of rice cultivation compared to conventional method where the rainfall is deficit.

Abstract:
A field experiment was conducted during 2 khar if and rabi seasons during 200608 with rice ( Or yza sativa L ) . wheat [ Triticum aestivum (L.) emend. Fiori & Paol.] cropping system at New Delhi. The main plots comprised 2 till- age treatments, viz. puddled and non-puddled in rice and with tillage and no-tillage in wheat. The subplots in- cluded 7 fertilizer treatments including recommended doses of urea (120 kg N/ha), urea + farmyard manure (FYM), urea + green manure (GM), urea + municipal solid waste (MSW) compost. Yields of rice and wheat were higher under puddled/conventional tilled condition compared to non-puddled/no-tillage conditions. Application of organic matter with recommended dose of mineral fertilizer gave the highest grain and straw yields compared to other treatments. The carbon sequestration potential was 0.146, 1.31, 1.165, 1.238, 0.728, 1.019 and 0.874 tonne C/ha under 120 kg N, 120 kg N + 6 tonnes FYM, 60 kg N + 6 tonnes FYM, 120 kg N+ 3 tonnes GM, 60 kg N + 3 tonnes GM, 120 kg N + 60 kg N (MSW compost) and 120 kg N + 60 kg N (MSW compost) treatments respectively, under puddle/tilled ricewheat cropping system. However, under non-puddled/no-tilled crops carbon sequestration potential were 0.291, 1.601, 1.456, 1.529, 1.019, 1.31 and 1.048 tonnes C/ha under treatment having 120 kg N, 120 kg N + 6 tonnes FYM, 60 kg N + 6 tonnes FYM, 120 kg N+ 3 tonnes GM, 60 kg N + 3 tonnes GM, 120 kg N + 60 kg N (MSW compost) and 120 kg N + 60 kg N (MSW compost) respectively. The addition of organic manures resulted in sequestration of carbon in ricewheat cropping system. The carbon sequestration increased under re- duced tillage conditions of soil.

Abstract:
Descriptions of the surface morphology of Vertisols presently use subjectively classed, descriptive attributes. A system to quantify the appearance of the soil structural components is required to allow the comparison of soils, and to determine effects of variation in climate and of chemical/physical ameliorants. A non-destructive method of quantifying surface structural features is presented. Ponded and puddled samples of the 0-20 mm surface layer of a self-mulching Vertisol and two non self-mulching Vertisols were subjected to either a continuous drying regime or a sequence of wetting/drying cycles. Structural development with time was assessed by quantifying structural features using photographs of the soil surface. With repeated wetting and drying the self-mulching soil developed crumb material, the smallest shrinkage blocks, and the widest cracks. The non self-mulching soils developed no crumbs and the cracks generally became narrower. The range of structural development in terms of 'good' to 'bad' self-mulching in the laboratory agreed with the soils' behaviour in the field. Within the range of experiments performed, puddled soils did not produce as 'good' a self-mulching surface as non-puddled soils, no matter how many drying/wetting cycles were carried out.

Abstract:
On-farm research was conducted at Gouripur sub-district under Mymensingh district of Bangladesh during the boro (mid November-June) season in 2013-14 and 2014-15 to evaluate the performance of non-puddled rice cultivation with and without crop residue retention. The rice var. BRRI dhan28 was transplanted by two tillage practices, viz., puddled conventional tillage (CT) and non-puddled strip tillage (ST) and at two levels of mustard residues, i.e., no-residue (R0) and 50% residue (R50). The experiment was designed in a randomized complete block design with four replications. There were no significant yield differences between tillage practices and residue levels in 2013-14. But in the following year, ST yielded 9% more grain compared to CT leading to 22% higher Benefit-Cost Ratio (BCR). Retention of 50% residue increased yield by 3% compared to no-residue, which contributed to 10% higher BCR. The ST combined with 50% residue retention yielded the highest grain yield (5.81 t ha-1) which contributed to fetch the highest BCR (1.06).

Abstract:
A two year longer on-farm research on conservation agriculture was conducted at Bhangnamari area of Bangladesh during November-June in 2014-15 and 2015-16 to evaluate the performance of non-puddled rice cultivation under increased crop residue retention. The rice variety BRRI dhan28 was transplanted under puddled conventional tillage (CT) vs. non-puddled strip tillage (ST) with 50% standing residue (R50) vs. conventional no-residue (R0) practice. The treatments were arranged in a randomized complete block design with four replications. There were no significant yield differences between tillage practices and residue levels in 2014-15. But in the following year, ST yielded 9% more grain compared to CT leading to 22% higher BCR. Retention of 50% residue increased yield by 3% over no-residue, which contributed to 10% higher benefit-cost ratio (BCR). Results of this two year on-farm study confirmed that the ST combined with 50% residue retention yielded the highest grain yield (5.81 t ha-1) which contributed to produce the highest BCR (1.06).

Abstract:
Rice-based intensive cropping systems require high input levels making them less profitable and vulnerable to the reduced availability of labor and water in Asia. With continuous conventional puddled rice transplanting, the situation is exacerbated by damaged soil structure, declining underground water and decreasing land and water productivity. To minimize these negative effects a range of new crop establishment practices have been developed (zero tillage, dry direct seeding, wet direct seeding, water seeding, strip planting, bed planting, non-puddled transplanting of rice, mechanical transplanting of rice crop and combinations thereof) with varying effects on soil health, crop productivity, resource saving and global warming mitigation potential. Some of these allow Conservation Agriculture (CA) to be practiced in the rice-based mono-, double- and triple cropping systems. Innovations in machinery especially for smallholder farms have supported the adoption of the new establishment techniques. Non-puddling establishment of rice together with increased crop residue retention increased soil organic carbon by 79% and total N (TN) in soil by 62% relative to conventional puddling practice. Rice establishment methods (direct seeding of rice, system of rice intensification and non-puddled transplanting of rice) improve soil health by improving the physical (reduced bulk density, increased porosity, available water content), chemical (increased phosphorus, potassium and sulphur in their available forms) and biological properties (microbiome structure, microbial biomass C and N) of the soil. Even in the first year of its practice, the non-puddled transplanting method of rice establishment and CA practices for other crops increase the productivity of the rice-based cropping systems. Estimates suggest global warming potential (GWP) (the overall net effect) can be reduced by a quarter by replacing conventional puddling of rice by direct-seeded rice in the Indo-Gangetic Plains for the rice-based cropping system. Moreover, non-puddled transplanting of rice saves 35% of the net life cycle greenhouse gases (GHGs) compared with the conventional practice by a combination of decreasing greenhouse gases emissions from soil and increasing soil organic carbon (SOC). Though the system of rice intensification decreases net GHG emission, the practice releases 1.5 times greater N2O due to the increased soil aeration. There is no single rice establishment technology that is superior to others in all circumstances, rather a range of effective technologies that can be applied to different agro-climates, demography and farm typologies.
