Diglossia among Students: The Problem and Treatment

This study aims at identifying the concept of diglossia, its causes and methods of treatment, and its negative effects. The researchers used the descriptive method. The study revealed the following most important results: Firstly,  the reason for language diglossia is contact between languages ​​and emergence of new other languages ​​or dialects which leads to a losing some of their original characteristics and qualities and the different environments within the same society that has a role in the emergence of diglossia. Secondly, it causes moving away from the mother tongue. Thirdly, the study also found that classical Arabic is the strongest ligament, which brings the peoples of the Arab nation together. Fourthly, diglossia can be reduced by simplifying classical rules of Arabic; facilitating the teaching methods and by paying attention to basic Arabic, which is supposed to be the focus of education for the emerging of mother tongue. Keywords: Diglossia, classical language, slang languag

Status of Dhaincha Incorporated Soil After Rice Harvest in (Boro) Rice–Dhaincha–Rice (T. Aman) Cropping Pattern

An experiment was conducted at Field Laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh, to find out the effect of dhaincha incorporation on subsequent rice crop yield and postharvest soil nutrient status. The experiment was laid out in a randomized complete block design having three replications. Nine dhaincha accessions were used as experimental materials along with a control (without dhaincha plant). Seeds of dhaincha accessions were sown in experimental plot @ 60 kg ha-1. Sixty days old dhaincha plants were mixed up with soil. Soil samples were collected twice, before sowing of dhaincha seeds and after rice crop harvest. Forty five days old healthy rice seedlings were transplanted in the well prepared dhaincha incorporated plots at the spacing of 15 cm x 25 cm (plant-plant x row-row). The pH and nutrient status were improved in dhaincha incorporated soil over the control. The highest grain yield (5.81 t ha-1) was obtained from dhaincha Acc. 33 incorporated plot followed by Acc. 25 (5.73 t ha-1) and the lowest in control (4.35 t ha-1). Due to the incorporation of dhaincha biomass in soil, the rice grain yield increased 7.82% to 33.56% over the control. Among the dhaincha accessions, number 33 showed the best performance in terms of influencing grain yield. A precise conclusion to be built up through collection of large number of germplasms from Bangladesh is needed
