<div><strong>Background:</strong> Bangladesh is one of the densely populated countries in the world. To meet up the increasing food demand there&rsquo;s no alternative to increase the cropping intensity through high yielding and short duration crop varieties. Currently, cropping system of Bangladesh is mostly rice based which is also the staple food. Therefore, farmers which follow rice-rice based cropping patterns are gaining less profit day by day. Contrary, intensive rice culture is depleting soil properties gradually. Thus, to preserve soil health and increase profit pulse and oil seed based cropping patterns are crucial for sustaining a cropping pattern. This study was undertaken to find out a cropping pattern with higher yield and profit in the context of Magura district.<br />
<br />
<strong>Methods: </strong>Five cropping patterns, CP1 = Transplanted Aman rice (cv. Binadhan-7)- Mustard (cv. Binasarisha-9)- Boro rice (cv. Binadhan-14); CP2 = T.Aman (cv. Binadhan-16)-Mustard (cv. Binasarisha-10)- Boro (cv. Binadhan-14); CP3 = T.Aman (cv. Binadhan-17) -Mustard (cv. Binasarisha-10)- Boro (cv. Binadhan-14); CP4 = T.Aman (cv. Binadhan-17)-&nbsp;Lentil (cv. Binamasur-8)- Sesame (cv. Binatil-3) and &nbsp;CP5 (Control) -&nbsp;Aman (cv. Shorna) &ndash; Boro (cv. Heera) - fallow were assessed to identify the most suitable and profitable pattern as well as to enhance the cropping intensity by adding a pulse or oil seed crop between two rice crops. The investigation was conducted at farmer&rsquo;s field of Magura during 2018-19. Block farming method was followed for experiment set up.&nbsp;<br />
<br />
<strong>Result:</strong> It was revealed that, maximum rice equivalent yield (REY) was obtained from CP1 (14.46 t/ha) followed by CP4 (13.52 t/ha), CP3 (13.35 t/ha), CP2 (13.09 t/ha) and CP5 (11.33 t/ha) during one year crop cycle. Highest gross margin (Tk. 1,90,189) and MBCR (1.83) was obtained from the cropping pattern CP4 and the lowest gross margin (Tk. 69,271) and MBCR (1.24) was found with the pattern CP5. Based on the above results it can be suggested that, Aman rice-Lentil-Sesame pattern i.e. CP4 may be a best choice for the farmers of Magura region for the maximum utilization of their land and gaining more profit compared to the other studied cropping patterns.</div>

<div><strong>Background:</strong> Lentil is the top cultivated pulse crop in Bangladesh. Even if there are a number of modern high yielding varieties (HYV) with all natural favorable conditions and resources for cultivation but due to lack available stress and climate (biotic and abiotic) resilient variety; potential yield of this crop is rarely met. Against huge sum of demand the supply is deficit in the country which is met by importing. Reflecting this situation, the present investigation attained to test the morpho-physiological and yield related attributes of seven HYV of lentil and depict the most suitable variety in terms of growth, yield and maturity.<br />
<br />
<strong>Methods: </strong>Binamasur-5, Binamasur-8, Binamasur-9, Binamasur-10, BARI Masur-5, BARI Masur-6 and BARI Masur-8 was laid in a randomized complete block design during the <em>rabi</em> (winter) season of 2019 at BINA sub-station farm, Magura.<br />
<br />
<strong>Result:</strong> Findings divulged that, Binamasur-10 had the most seed yield (2.08 t/ha), harvest index (HI) (25.15%) and with medium duration of maturity (108.94 days). BARI Masur-5 produced maximum stover yield (7.86 t/ha) with delayed maturity (114 days) and least seed yield (1.75 t/ha) among the evaluated varieties. Correlation study exposed that, seed yield had a positive and significant relationship with plant height (0.78*), number of primary and secondary branches (0.76* and 0.75*), total dry mass (0.87**) and HI (0.85**). However, Binamasur-10 might be more suitable than the other varieties in the field due to it&rsquo;s notable performance.</div>
