The study was conducted at the On Farm Research Division (OFRD) farm, Rangpur from 2002-2003 to 2004-2005 to see the effect of inorganic fertilizers along with organic manure and mungbean residue on soil properties and yield of crops. For the first crop (maize), there were five treatments. After harvest of maize, mungbean and dhaincha (Sesbania) seeds were sown as per treatments. For T. Aman ri...

The rice–wheat cropping system is the main food bowl in Asia, feeding billions across globe. However, productivity and long-term sustainability of this are threatened by stagnant crop yields greenhouse gas emissions from flooded rice production. negative environmental consequences excessive nitrogen fertilizer use further exacerbating situation, along with high labor water requirements transpla...

carbon (c) and organic nitrogen (n) mineralization processes play key roles in supplying nutrient elements essential for plant growth. on the other hand, since the low organic matter content of agricultural soils of arid and semi-arid areas, microbial activities are often limited by carbon in these types of soils. enhancement of microbial activities and populations could be achieved by returnin...

Abstract Plant residues are often used as soil amendments in laboratory experiments, but they can reportedly release compounds interfering with DNA extraction and subsequent molecular biological analyses. Theoretically, for accurate comparison of microbial community composition soils without added plant after a period incubation, no significant difference at the beginning experiment is required...

The cooking quality of rice is associated with the starch gelatinization temperature (GT). Rice genotypes with low GT have probably been selected for their cooking quality by humans during domestication. We now report polymorphisms in starch synthase IIa (SSIIa) that explain the variation in rice starch GT. Sequence analysis of the eight exons of SSIIa identified significant polymorphism in onl...

A gas chromatography mass spectrometry with spike calibration curve method was used to quantify three carbamate pesticides residue in cooked white rice and to estimate the reduction percentage of the cooking process duration. The selected pesticides are three carbamate pesticides including carbaryl and pirimicarb that their MRL is issued by “The Institute of Standards of Iran” and propoxur whic...

Excessive nitrogen (N) fertilization, low use efficiency, and heavy pollution are the dominant issues that exist in intensively cultivated double rice cropping systems China. Two-year field 15N microregion experiments were conducted to evaluate N fate a soil-rice system under series of different rate treatments from 2020 2021. The economic application simultaneously improved yield efficiency ro...

Rice flour, corn flour and deoiled rice bran blends were used to prepare ready-to-eat extrudates

Straw application can not only increase crop yields, improve soil structure and enrich soil fertility, but can also enhance water and nutrient retention. The aim of this study was to ascertain the relationships between straw decomposition and the release-adsorption processes of K(+). This study increases the understanding of the roles played by agricultural crop residues in the soil environment...
