Abstract:
... By the late 1960s, it was becoming clear that the Green Revolution (GR) had succeeded only in part. Although crop yields, total production and food-per-capita were substantially higher, GR programmes were also increasing social inequality and damaging the environment, both of which began to attract attention in professional journals and the popular press. In this paper I examine the ways in which ...

Abstract:
... Seed germination and early seedling development are two critical phases in plant lifecycle that largely determine crop yield. Phytohormones play an essential role in governing these developmental processes; of these, ethylene (ET; C₂H₄), the smallest gaseous hormone, plays a major role via crosstalk with other hormones. Typically, the mechanism of hormone (for instance, auxin, cytokinins, ET, and ...

Abstract:
... Soybean (Glycine max), as an economically important food and oilseedcrop, is a major source of plant proteins and oils. Although considerable progress has been made in increasing the yields of rice, wheat, and maize through the “Green Revolution”, little improvements have been made for soybean. With the increasing demand of soybean production and the rapid development of crop breeding technologies ...

Rice seeds ejected by a rotating disc are caused to rebound by a baffle ring, to produce a non-hollow, fan-shaped distribution at field level. Three factors produce influences on the distribution, and they are the rotation of the disc, UAV flying height and the angle of the baffle ring. The di ...

Abstract:
... Strigolactones (SLs) are a class of plant hormones involved in several biological processes that are of great agricultural concern. While initiating plant–fungal symbiosis, SLs also trigger germination of parasitic plants that pose a major threat to farming. In vascular plants, SLs control shoot branching, which is linked to crop yield. SL research has been a fascinating field that has produced a ...
