The climate of Ghana is tropical. [1] The eastern coastal belt is warm and comparatively dry, the south-west corner of Ghana is hot and humid, and the north of Ghana is hot and dry. [2] Ghana is located on the Gulf of Guinea, only a few degrees north of the Equator, giving it a warm climate. [3]
Among xanthomonads, X. o. pv. oryzae causes bacterial blight (BB) of rice which is one of the most important diseases of rice in most of the rice growing countries. [ 2 ] Bacterial blight of rice has high epidemic potential and is destructive to high-yielding cultivars in both temperate and tropical regions especially in Asia .
Most subtropical climates fall into two basic types: humid subtropical (Köppen climate classification: Cfa/Cwa), where rainfall is often concentrated in the warmest months, for example Southeast China and the Southeastern United States, and dry summer or Mediterranean climate (Köppen climate classification: Csa/Csb), where seasonal rainfall ...
Rice fields in Dili, East Timor. Rice is the major food amongst all the ethnic groups in Nepal. In the Terai, most rice varieties are cultivated during the rainy season. The principal rice growing season, known as "Berna-Bue Charne", is from June to July when water is sufficient for only a part of the fields; the subsidiary season, known as ...
The System of Rice Intensification (SRI) is a farming methodology that aims to increase the yield of rice while using fewer resources and reducing environmental impacts.. The method was developed by a French Jesuit Father Henri de Laulanié in Madagascar [1] and built upon decades of agricultural experimentat
While it was first designed for tropical and subtropical areas, the system now applies globally. The system has been shown to fit not just tropical vegetation zones, but Mediterranean zones, and boreal zones too, but is less applicable to cold oceanic or cold arid climates where moisture becomes the predominant factor.
Oryza glaberrima, commonly known as African rice, is one of the two domesticated rice species. [1] It was first domesticated and grown in West Africa around 3,000 years ago. [2] [3] In agriculture, it has largely been replaced by higher-yielding Asian rice (), [2] and the number of varieties grown is declining. [1]
The IPM approach calls for keeping the pest populations below the levels at which they cause economic injury, not total eradication. IPM in its pure form is complex, and beyond the ability of most farmers to manage; however, the underlying principles have gained widespread acceptance in the tropics, with most governments sponsoring IPM ...
