A field experiment was conducted to study the comparative performance of zinc in biofortified rice and their effect on yield attributes, concentration at BAU farm, Sabour Randomized Block Design replicated thrice during Kharif season 2021-22. The variety used Aaayush. soil experimental plot silt loam having pH 7.7, organic carbon 0.53%, Low available Nitrogen (159.88 kg/ha), Phosphorus (26.94 k...

Mechanical hill direct seeding of hybrid rice could be the way to solve the problems of high seeding rates and uneven plant establishment now faced in direct seeded rice; however, it is not clear what the optimum hill seeding density should be for high-yielding hybrid rice in the single-season rice production system. Experiments were conducted in 2010 and 2011 to determine the effects of hill s...

Heritable changes of phenotype arising in plant ontogenesis by the influence of environmental factors belong to the most intriguing genetic phenomena. An unusual inheritance pattern was detected during examination of male fertility restoration in the CMS-inducing "9E" type cytoplasm of sorghum: Rf-genes were functional in self-pollinated progeny of F(1) hybrids yet were either not expressed or ...

Knowledge of arsenic (As) accumulation in rice (Oryza sativa L.) is important for minimizing As transfer to the food chain. The aim of this study was to investigate the role of rice nodes in As storage and distribution. Synchrotron μX-ray fluorescence (μ-XRF) was used to map As distribution in the top node and internode of a lsi2 mutant defective in silicon/arsenite efflux carrier and its wild-...

It is sometimes argued that women play a more important role in seed and diversity management than men,and that women have greater abilities in managing crop diversity. In The Gambia, men and women also havethe belief that women are better in managing and identifying varieties than men. This article focuses on therole of gender in farmer management of crop diversity in two crops...
