This experiment was performed to investigate the effect of Azolla and rice straw mixed compost in peat substitution on Dieffenbachia amoena. Factorial experiment based on a completely randomized design with two factors of nutrient solution in 2 levels (1- without solution, 2- with 130 mg N/ l, 32 mg P /l and 117 mg K/ l) and 5 levels of Azolla and rice straw mixed compost (zero, 15, 30, 45 and ...

Harnessing stem carbohydrate dynamics in grasses offers an opportunity to help meet future demands for plant-based food, fiber and fuel production, but requires a greater understanding of the genetic controls that govern the synthesis, interconversion and transport of such energy reserves. We map out a blueprint of the genetic architecture of rice (Oryza sativa) stem nonstructural carbohydrates...

rice is among the most important food crops throughout the world. hybrid rice benefits from about a 30 percent yield advantage over the conventional pure line varieties and this phenomenon can play an important role in fighting world hunger. to diminish the damage of rice pests, development of insect pest management strategies in hybrid rice is necessary. this study was aimed at evaluating the ...
