However, it remains unclear as to the time for such treatments to have a positive effect. In this study of lentil‐mung bean‐rice and wheat‐mung‐rice rotations in Bangladesh positive effects of strip planting or bed planting, along with residue return, on SOC pools were apparent after 1.5 years, compared with intensive conventional tillage and limited residue return. Conventional tillage resulted in higher CO2 emission compared with strip planting or bed planting as did high residue return. In the cereal‐dominated rotation, the strip planting system sequestered carbon at a rate of 0.24–0.53 Mg C ha−1 year−1 (at 0–0.15 m depth) while conventional tillage was associated with a carbon loss of 0.52–0.82 Mg C ha−1 year−1. In the legume‐dominated rotation, neither practice sequestered SOC. Under strip planting, a minimum annual crop residue input of 1.7 Mg C ha−1 for the cereal‐dominated system and 5.2 Mg C ha−1 for the legume‐dominated system was required to maintain SOC at equilibrium. We conclude that strip planting with high levels of crop residue return can be an effective and quick strategy in either slowing the loss of SOC or improving C sequestration in the intensive rice‐based systems of the Eastern IGP.

Increasing cropping intensity and cultivation of modern varieties with high yield potential are the major reasons of nutrient depletion from soil, which results in decline of crop yield. With an objective of studying delineation of soil micronutrient status, their depleting trend over time, relationship with other soil variables and interrelationship among micronutrients, a study was carried out in Old Meghna Estuarine Floodplain (AEZ 19) soils of the country. In the present study, soil analysis of top soils (0-15 cm soil depth) shows that availability of Zn and B declined after a decade of time. However for other micronutrients, viz. Cu, Mn and Fe, still prevailing high status. Micronutrient levels of subsoil (15-30 cm soil depth) were in general lower than those of top soils. The soil Zn had significant positive correlation with clay content (r=0.712**) and its availabili...

Boron was applied at 0, 1, and 2 kg/ha. The mustard variety BARI Sarisha-8, (B. napus group) was selected for the experiment. Effect of B was evaluated in terms of yield and mineral nutrients (N, P, K, S, Zn, and B) uptake. The mustard crop responded significantly to B application. The optimum rate of B was found to be 1 kg/ha There was no significant difference between 1 & 2 kg B/ha in all the years. Boron and N concentrations of grain and stover were significantly increased with increased rate of B application indicating that B had positive role on protein synthesis. In case of P, S, and Zn, the concentrations were significantly increased but in case of K, it remained unchanged in stover. The grain B concentration increased from 19.96 μg/g in B control to 45.99 μg/g and 51.29...

The study was conducted to evaluate the effect of lime and manure on soil fertility, nutrients and yields of wheat, mungbean and rice. Experiments were done at Agricultural Research Station (ARS), Bangladesh Agricultural Research Institute (BARI) farm and farmer field over two consecutive years with the cropping pattern, namely wheat-mungbean-transplanted (T.) aman rice/monsoon rice. The varieties used were Bijoy for wheat, BARI mung6 for mungbean and Bina dhan7 for T. aman rice. There were nine treatment combinations with three lime levels (0, 1 and 2 ton dololime ha-1) and three manure treatments (poultry manure, farmyard manure and no manure) with three replications. The rate of poultry manure was 3 t ha-1 and that of farmyard manure was 5 t ha-1. Nutrients from manure sources were supplemented wit...

Performances of the genotypes were evaluated with respect to grain set, boron uptake and grain yield. The genotypes differed considerably in their response to added boron. Some commonly grown varieties such as ‘Sourav’, ‘Prodip’ and ‘Sufi’ showed little response to boron application, while ‘Shatabdi’ had a high response to added boron, thus the former varieties can be regarded as boron efficient and the later as boron inefficient. Some advanced lines, ‘BAW 1051’, ‘BAW 1086’ and ‘KRL-1-4’, also demonstrated their performances as boron efficient genotypes. Wheat genotype response to added boron showed considerable variation between two years, so it is unclear that under what conditions the boron translocation from the v...

In Bangladesh, depletion of soil fertility is a serious threat to sustainability of agricultural production due to high cropping intensity and agriculture practices based on conventional tillage and residue removal (Rijpma and Jahiruddin, 2004). In this situation, CA practices (minimum tillage, crop residue retention and diverse crop rotations) could be a good option for the improvement of soil quality and crop productivity in Bangladesh. However, CA practices are poorly developed for intensive rice-based cropping system and their effect on SOM, plant nutrients and system productivity have not yet been properly addressed. Hence, the present study was undertaken to monitor the changes in SOM and other plant nutrients with system productivity under CA practices in the rice-jute cropping system in the Low Ganges River Floodplain of Bangladesh.

The utilization of homestead is very important. Intensive crop cultivation with high yielding varieties to fulfil food demand for a swelling population has led to mining out the inherent plant nutrients from the soil. An experiment was conducted with tomato-okra-stem amaranth cropping pattern in a homestead area in Chhiata Series of Grey Terrace Soil (Aric Albaquept) under AEZ- 28 at Gazipur to find out the optimum dose of chemical fertilizer and organic manure for obtaining higher crop yield and to study the effect of integrated nutrient management (INM) on soil properties. The experiment consisted of eight treatments: T 1 (Poultry manure, PM @ 5 t ha -1), T 2 (Cowdung, CD @ 10 t ha -1), T 3 (Household waste, HW @ 10 t ha -1), T 4 (PM @ 2.5 t ha -1 + reduced recommended dose of fertilizer, RDF), T 5 (CD @ 5 t ha -1 + reduced RDF), T 6 (HW @ 5 t ha -1 + r...
