Effect of variety and nitrogen application on the nutritive value of rice straw and stubble
AbstractA field study was conducted to compare the nutritive value of straw and stubble from six varieties of rice grown under two levels of nitrogenous fertilizer application. The nutritive values of stubble harvested directly after straw harvest (stubble 1) and that allowed to regrow for two weeks (stubble 2) were also studied. The assessments were based on crude protein content (CP) and in vitro organic matter digestibility (IVOMD). Level of fertilizer, variety and part of the plant (straw/stubble) caused significant changes (P < 0·05) in the CP values. Also, the variety × plant-part interaction was significant (P < 0·05). The mean CP content for straw was significantly lower than for stubble (5·3 and 5·5), and the values for the different varieties ranged from 4·9% to 5·9%. Variety and part of the plant showed significant (P < 0·0001) effects on IVOMD, whereas effects due to level of fertilizer were not significant. The overall IVOMD values show more relevant differences than the CP values, straw being significantly higher than the stubble (40·2 and 35·0%). Within the six varieties, the IVOMD of straws and stubbles ranged from 32% to 47%, and 30% to 43%, respectively. Depending on the variety, the increase in IVOMD between stubble 1 and stubble 2 could range from 3 to 23 digestibility units.
