The basal diets (starter and grower) were formulated and divided into five portions. The first portion (T1) had no supplementation; portion two (T2) had 1.1 g/100g oxytetracycline (OT) supplementation. 15g/kg papaya seed powder, mustard seed powder, and black cumin seed powder were added to portions three (T3), four (T4), and five (T5), respectively. The haematological indices were not significantly affected by the dietary treatments. The birds' relative growth rate was improved by oxytetracycline, papaya, mustard, and black cumin dietary supplementation. The serum alanine aminotransferase concentration of the broiler chickens in T1 was not statistically significantly different compared to T2, T3, and T4. Birds in treatments T1 and T2 had serum albumin concentrations that were comparable to those fed T3 and T4 supplemented diets but statistically lower (<em>p <0.05</em>) than T5. Weekly growth rate and relative growth rate were significantly improved under T3 and T4.https://applied.dysona.org/article_129475_36a7b7093b796d20693ddc9748bb8c70.pdfE-NAMTILADYSONA - Applied Science2708-62832320210701Single-pass tillage combined with herbicides and rice stubbles enhances weed control and yield of rapeseed in Bangladesh364613269510.30493/das.2021.288244ENMohammad MobarakHossainRice Breeding Innovation Platform, International Rice Research Institute, Philippines0000-0003-0640-3209Begum MahfuzaDepartment of Agronomy, Bangladesh Agricultural University, Bangladesh0000-0003-2754-4692Rahman MoshiurDepartment of Agronomy, Bangladesh Agricultural University, Bangladesh0000-0001-6601-8682Journal Article20210528South Asian farmers are turning to mechanized planting, crop stubble retention, and herbicide application to address the current labor shortage situation. The purpose of this on-farm study was to compare conventional plow tillage combined with manual weeding to single-pass tillage combined with herbicides on the overall weed control efficacy and seed yield ofrapeseed(<em>Brassica napus</em> L.) under northern Bangladesh conditions. During 2014–2016, the rapeseed variety ‘BARI Mustard-14’ was grown under two different tillage systems, plow tillage and single-pass tillage with zero-stubble and 50% standing stubbles of previously grown monsoon rice. The plow tillage was conducted using a two-wheel, while the single-pass tillage was performed using a versatile multi-crop planter. In plow tillage, weeds were managed by hand on three dates. In single-pass tillage, a pre-plant herbicide (glyphosate), pre-emergence herbicide (pendimethalin), and post-emergence herbicide (isoproturon) were applied for weed control. Data revealed that the combination of single-pass tillage and herbicides with 50% rice stubbles resulted in the highest weed control efficacy. Additionally, this practice resulted in a 20% yield increase and a 70% increase in benefit-cost ratio compared with plow tillage and hand weedings combination without keeping any rice stubbles in the field.https://applied.dysona.org/article_132695_8c044f9e41a21741e987113defebb35e.pdf
