This study was conducted to know cropping cycles required improve OM status in soil and investigate the effects of medium-term tillage practices on properties crop yields Grey Terrace Bangladesh under wheat-mungbean-T. aman system. Four different practices, namely, zero (ZT), minimum (MT), conventional (CT), deep (DT), were studied a randomized complete block (RCB) design with four replications. Tillage showed positive yields. After cycles, highest accumulation, maximum root mass density...
We review the recent development of Conservation Agriculture (CA) for rice-based smallholder farms in Eastern Gangetic Plain (EGP) and underpinning research on agronomy, weed control, soil properties greenhouse gas emissions being tested to accelerate its adoption Bangladesh. The studies are based mostly minimum disturbance planting strip (SP) mode, using Versatile Multi-crop Planter (VMP), powered by a two-wheel tractor (2WT). One-pass SP with VMP decreased fuel costs crop establishment up...
Rice-based intensive cropping systems require high input levels making them less profitable and vulnerable to the reduced availability of labor water in Asia. With continuous conventional puddled rice transplanting, situation is exacerbated by damaged soil structure, declining underground decreasing land productivity. To minimize these negative effects a range new crop establishment practices have been developed (zero tillage, dry direct seeding, wet strip planting, bed non-puddled...
SUMMARY Conservation agriculture (CA) is inadequately developed for rice-based cropping systems widely practiced in Bangladesh. The current drawback the implementation of CA all crops including rice ( Oryza sativa L., ecotype ‘transplanted aman’ [T. aman]) to increase rice–wheat Triticum aestivum L.) rotation productivity. It important identify best combination tillage types and achieve a high yield component improve soil health. Three practices, assigned main experimental plots [namely,...
Zero tillage increases stratification of immobile nutrients such as P. However, it is unclear whether near-surface soil P eases or hampers uptake by maize (Zea mays L.) which needs an optimum supply at/before six–leaf–stage to achieve potential grain yield. The aim the three-year study was determine stratification, under zero tillage, impaired yield and placement methods could improve on Aeric Albaquept subgroup. Phosphorus fertilizer placed by: (a) broadcasting before final sowing seeds;...
A cropping system that is based on three or four crops currently a widely favored option for augmenting crop productivity to address the escalating global food demand. However, improper fertilizer management and undue tillage adversely impacts both of fertility soil. research investigation was conducted nutrient within mustard-mungbean-Transplanting aus (T.aus)-Transplanting aman (T.aman) examine impact packages techniques overall systems, as well condition soil in grey terrace The included...
Minimum soil disturbance and increased crop residue retention practices are promising options to enhance organic matter, nutrient concentration yield. However, the potentials of in improving properties, increasing yield ensuring economic return have not been tested monsoon rice (Oryza sativa L.)-lentil (Lens culinaris L.)/wheat (Triticum aestivum L.)-jute (Corchorus L.) cropping systems on seasonally flooded lowlands Eastern Gangetic Plain South Asia. A field trial for consecutive three...
The effects of conservation agriculture (CA) practices on soil properties along with crop yields rice-based triple cropping systems have not been adequately assessed in Bangladesh. An experiment was conducted at Bangladesh Agricultural Research Institute, Gazipur, from 2009 to 2012 assess the tillage and residue retention physical properties, organic carbon (SOC) a wheat-mungbean-rice system. Treatments consisted three (MT: minimum tillage; CT: conventional DT: deep tillage) eight levels...
Conventional tillage (CT) degrades soil and environmental quality in many major cropping systems. Conservation agriculture, like reduced tillage, can play an important role maintaining organic carbon (SOC) storage minimizing greenhouse gas (GHG) emissions from crop fields. An experiment was conducted at the Bangladesh Agricultural Research Institute (BARI), Gazipur to evaluate GHG emission, global warming potential (GWP), intensity net SOC variations rice-mustard-rice systems under CT strip...
A series of field experiments was conducted at BARI central farm to observe the changes in soil densities, moisture retentive properties, and crop productivity as influenced by different tillage depths cropping patterns. The depth showed significant effect on wheat yield. Grain yield significantly increased from 2.86 t/ha (minimum depth) 5.33 (tillage up 20-25 cm). Tillage patterns individually their interaction affected BRRI dhan32. highest grain rice (5.82 t/ha) found cm under...
A series of experiments using nine treatment combinations comprising three tillage practices (zero tillage, conventional and deep tillage) cropping patterns (wheatfallow- T. aman, wheat–mungbean-T. aman wheat-dhaincha-T. aman) were examined in a split- plot design at Bangladesh Agricultural Research Institute (BARI), Gazipur, during 2008-2009 2009-2010 to study the effect different on soil physical properties crop productivity previously puddled soil. Soil viz. bulk density, particle density...
An experiment was conducted at the Agronomy Field of Patuakhali Science and Technology University, Dumki, from June to December, 2013 find out effect variety planting density on yield attributing characters local aromatic rice. The laid in a factorial randomized complete block design with three replications, which consisted rice varieties (Chinigura, Shakhorkhora Kalizira) four densities were viz. S1 (25 cm × 20 cm), S2 (20 S3 15 cm) S4 10 cm). results revealed that var. produced highest...
In intensive crop production systems, sustainable agricultural development strives to find the balance between productivity and environmental impact. To reduce N fertilizer-associated risks of cropping, sound agronomic environmentally acceptable management practices are urgently needed. attain high yields, improve soil health, ensure economic return usage efficiency in conservation-based agriculture, must be optimized, which has not yet been studied systematically mustard-boro rice-aman rice...
Very little is known about the changes that occur in soil organic carbon (SOC) and total nitrogen (TN) under an intensive rice-based cropping system following change to minimal tillage increased crop residue retention Gangetic Plains of South Asia. The field experiment was conducted for 3 years at Rajbari, Bangladesh examine impact practices on (C) (N) cycling. comprised four practices—conventional (CT), zero (ZT), strip-tillage (ST), bed planting (BP) combination with two levels—increased...
An experiment was conducted in Hill Agricultural Research Station (HARS), Khagrachari during 2011-2012 to estimate the soil loss and changes properties under indigenous cultivation methods of ginger, turmeric, aroid, jhum rice hill slopes. The use for growing different crops has created negative impact on productivity slope. Among four crops, annually highest (22.68 t/ha) occurred by ginger which statistically similar with turmeric (16.52 followed aroid (12.02 lowest (7.92 cultivation. There...
Conservation agriculture (CA) with appropriate nutrient management can help increase crop production, improve soil health and bring economic return. An experiment was conducted at farmer’s field of Rajbari district under Low Ganges River Floodplain (AEZ-12) during 2017-2018 to evaluate the effects tillage on system productivity profitability in jute - T. Aman rice- onion cropping system. Strip (ST) for jute, non-puddling rice one pass minimum (MT) contrasted conventional establishment...
The experiment was conducted to study the effect of tillage, mulch and irrigation on soil moisture, yield attributes hybrid maize (var. BARI Hybrid Maize-6). Two tillage practices (minimum conventional tillage), two levels mulches (no rice straw @ 3 t ha-1) three frequencies (one at 32 days after sowing (DAS), irrigations 55 DAS 32, 85 were used as treatment variables. Twelve combinations assigned in a split-split plot design with replications. Minimum conserved more moisture than no both...

The soil of grey terrace is vulnerable due to the limitations organic matter and fertility. Cropping pattern-based crop cultivation under conservation tillage pre-requisite increase productivity conserve resources for challenging food demand over growing population. Single-cropping typically used in soil, leaving leftover nutrients which deprived nation producing a sustainable manner. A study on practices integrated fertilizer techniques has been conducted solve these challenges...
