Four rice cultivars have been grown under three graded fertility in partially reclaimed sodic soil to evaluate their suitability with respect to yield potentia, physical, thermal and chemical characteristics. In general, although increasing the fertility levels enhanced significantly the grain and straw yield of all rice cultivars yet length: girth ratio, water uptake, volume expansion and starch content of each cultivars have been showed reverse trends. However, the percentage of protein and mineral matter alongwith kernal elongation & length of paddy grains increased due to increasing the fertility grades but could not reach the level of significance.
Maximum grain and straw were notices by ‘Sita’ rice cultivar followed by Saket-4, Sarjoo-52 and minimum was observed by ‘Jaya’ during both the years as well as all fertility levels. Although, none of these fertility levels could markedly increased the quality characteristics and classification of theses yet the quality parameters significantly improved due to specific genetical attributes of rice cultivars.
