Abstract:
In the Republic of Guinea, the system of intensive rice cultivation was introduced about a decade ago with little expansion into rural areas. It is in this context that we carried out this study of the effects of intensive and traditional rice cultivation systems on the yield and biochemical composition of the rice grain at ISAV/F to know the limits of SRI in improving the grain quality. The work took place from June 25 to December 15, 2020 in the Urban Commune of Faranah for culture and from February 10 to April 13, 2021 in Conakry at the Laboratory of Central Veterinary Diagnostic (LCVD), Food Hygiene Section in Conakry located at the Ministry of Agriculture in the Municipality of Kaloum. The aim of the research is to see the effects of rice cultivation systems on the yield and nutritional value of the rice grain. The plant material used consisted of four varieties Binyana, Diana and Soronkadi (local) and CK211 (improved). The parameters evaluated are the yield per hectare, the growing cycle and the biochemical parameters. The data collected was subjected to statistical analyzes using Excel, SPSS 21 and Sigma Plot 12.5 software. The results of these analyze show that in terms of yield, SRI proved to be better on all varieties with relatively short vegetative cycles. For biochemical quality, parameter averages of four varieties show an increase in content by SRI in moisture, fat, mineral and protein levels; a reduction in the content of carbohydrates in this same system and a uniformity of the systems for the rate of dry matter. Yield has a strong positive correlation with protein content and a very strong negative correlation with those carbohydrates.
