Abstract
Black rice is considered as super food due to its various health benefits to the human being. In Bangladesh this rice is cultivated in a very limited area of Chittagong hill tracts and its cultivation technique in plain land ecosystem is still unknown. Therefore, a study was undertaken to evaluate the performance of few black rice cultivars cultivated year-round in plain land environment. The experiment was performed at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh. The experiment comprised two factors viz. A) three rice cultivars: Kongnam ene, Gelong ni and Gelong se; and B) Twelve date of transplanting starting from 01 July 2018 to 01 June 2019. The experiment was laid out in a split plot design where date of transplanting was distributed in main plots and rice cultivars were allocated in sub plots. It has been found that cultivar Kongnam ene can be cultivated as a short duration variety as it required only 40 days to panicle initiation, 60 days to flowering and 80 days to harvesting after transplanting. All the three cultivars can be cultivated in all the three seasons viz. aus, aman and boro. The cultivar Gelong ni produced significantly highest grain yield (4.0 t/ha) among the cultivars when transplanted in January (boro season).
Highlights
Black rice is a type of the rice species Oryza sativa L. which is glutinous, packed with high level of nutrients and mainly cultivated in Asia
For harvesting it has been found that the black rice variety Knongnam ene took only 80 days after transplanting while the other two varieties viz. Gelong ni and Gelong se took the same times (92 days) for harvesting (Figure 1)
It is found that total growth duration (TGD in days) from seed to seed, cultivar gelong ni required the maximum number of days (114 days)
Summary
Black rice is a type of the rice species Oryza sativa L. which is glutinous, packed with high level of nutrients and mainly cultivated in Asia. The pericarp (outer part) of kernel of this rice colour is black due to a pigment known as anthocyanin, an antioxidant. Many people assume this rice as a panacea of many culinary diseases because of its high nutritive value and curative effect. This rice is supposed to enhance the longevity of life, it is known as long life rice. Ancient Chinese history claims that black rice was solely for the Emperor and the Royal family due to its nutritional and healing abilities (Oikawa, 2015)
