“…Other studies have also showed positive balance of Zn and B in maize-mungbean-rice system when it was added [21]. Similar results corroborated by Jahan et al [41] in a monocrop cultivation of T. aman rice where -0.08 to -0.31 kg Zn ha -1 yr -1 was in control and farmers practice and positive balance (1.12 to 1.61 kg Zn ha -1 yr -1…”

Field experiments on Wheat-Mungbean-T. aman cropping pattern were conducted at Regional Pulses Research Station (RPRS), Madaripur in calcareous soils under Low Ganges River Floodplain (?EZ-12) during 2009 to 2010 to prepare nutrient balance sheet for the cropping pattern and fertilizer recommendation for study area. The treatments were T1= Control; T2 = Farmers practice; T3 = AEZ based recommended fertilizer dose and T4 = Soil test based fertilizer dose. The experiment was laid out in RCBD with three replications. Results revealed that the average yields of wheat, mungbean and T. aman ranged from 1517 to 3124 kg ha-1, 1320 to 1863 kg ha-1 and 2974 to 4859 kg ha-1, respectively. Grain yield of all crops increased significantly higher in soil test based (STB) fertilizer treatment (T4) over the other treatments. Among the major nutrients, the magnitude of negative balance was greater with N and K followed by Mg and Ca. The negative balance of N (-56.0 to -183 kg ha-1), K (- 71.0 to -167 kg ha-1), Ca (-7.50 to -27.1 kg ha-1), and Mg (-16.7 to -35.7 kg ha-1) was observed in all the managements might be due to added lower amount of nutrients in soil and higher removal by the crops from the soil. Positive balance of P indicated that the added amount of P is larger than the removal; P fertilization was enough to make apparent balances positive. Across various treatments, there was some amount of positive apparent S balance except absolute control plots and farmers practice. On the other hand, Zn and B balance in the system was neutral to slightly positive. Results revealed that, N, K, Ca, and Mg balance after two years of cropping was negative regardless of soil type and management strategies adopted. There was an improvement in organic matter in all treatments where biomasses of mungbean were incorporated. Organic matter, N, P, S, Zn and B status in soil was improved due to soil test based fertilization over the initial status. Considering the gross margin and soil fertility the soil test based (STB) fertilizer management practice is economically profitable and sustainable.Bangladesh J. Agril.

“…So, the AEZ (T 3 ) and soil test based treatments (T 4 ) showed positive balance of Zn. Similar results corroborated by Jahan et al (2015b) in a monocrop cultivation of T. aman rice where -0.08 to -0.31 kg Zn ha -1 yr -1 was in control and farmers practice and positive balance (1.12 to 1.61 kg Zn ha -1 yr -1 ) was in AEZ and STB treatment. Deficiency detection of Zn in mustard, mungbean and T. aman rice in all treatments suggested for application of Zn fertilizer or further monitoring (Bell & Kovar, 2000;Kalra, 1998).…”

The experiment was conducted to measure crop yields, nutrient concentration, nutrient uptake and balance by using different nutrient management practices for mustard-mungbean-T. aman rice cropping system in calcareous soil of Madaripur, Bangladesh. Different nutrient management practices were absolute nutrient control (T 1 ); farmer's practice (T 2 ); AEZ based nutrient application (T 3 ) and soil test based nutrient application (T 4 ). The practices were compared in a randomized completely block design with three replications over two consecutive years. The average yield through application of soil test based nutrient (T 4 ) was showed effective to get highest yields of mustard (1530 kg ha ). The same practices (T 4 ) exhibited the greatest nutrients uptake by the test crops. The apparent balance of N and K was negative; however it was less negative and less deficiency detect in T 4 treatment. Positive balance of P observed in all practices except in T 1 . There was a positive S balance (7.60 kg ha -1 ) in T 4 but negative in T 1 , T 2 and T 3 . Zinc balance was found positive in T 3 and T 4 and negative in T 1 and T 2 . Boron balance in the system was neutral or slightly positive in T 1 and negative in T 2 but positive in T 3 and T 4 . Organic matter, N, P, S, Zn and B status in soil was improved by T 4 treatment. The results suggested that the soil test based nutrient application is viable and sustainable for mustard-mungbean-T. aman rice cropping system in calcareous soils of Bangladesh.
