“…Nitrogen is a nutrient being applied in greater quantities in crop production (Pyngrope et al, 2019) which is a common practice in Kuttanad also. Despite this, the soils showed an available N content ranging from 275.70-502.95 kg h -1 which remained below the higher N availability class (>560 kg h -1 ).…”

Article InfoFluoride contamination has now become an emerging concern in agroecosystems. A diagnostic survey was conducted across the fluoride (F -) contaminated wetlands of Kuttanad, India with an aim to examine the influence of edaphic factors on Fconcentration in soils. The soils (Inceptisols) predominantly sandy had a substantial percentage of clay and the soil characteristics such as bulk density (BD), moisture, temperature, pH, electrical conductivity (EC), cation exchange capacity (CEC) and organic carbon (OC) varied with soils. Similarly, the soil nutrients (NPK) and the oxides of Fe and Al as well as total sesquioxide differed with soils. Principal component analysis (PCA) revealed that the first two components (PC1 and PC2) significantly explained the variability existed in the data while the third component (PC3) did not explain any variation compared to the first two components. PC1, PC2 and PC3 accounted for 52.2%, 12.7% and 11.3% of the variation in the profiles respectively. Out of soil samples, 53% had a similar distribution of soil characteristics and Fconcentration and are grouped together in PC1 while, the remaining 47% of the samples had a similar distribution of characteristics and are grouped together in PC2. Among the soil characteristics examined, silt content, pH, EC, CEC, OC, N and P had a significant (P<0.001) positive association along PC1 indicating that these factors are contributing to the augmentation of Fconcentration in the wetlands of Kuttanad.

In this paper, the morpho-agronomic diversity of rice in F2 generation were further analyzed. A total of 20 genotypes (Sintanur and Logawa as parents, 9 genotypes F2 SL (Sintanur x Logawa), 9 genotypes F2 LS (Logawa x Sintanur)) were investigated for culm color, plant height, flowering time and harvest time. Data were binary-coded for each genotype and calculated using Jaccard’s coefficients, and then were used to construct dendrogram using UPGMA employing the SAHN from the MVSP 3.1. software. Heritability and inbreeding depression were analysed. Analysis of morpho-agronomic diversity showed there were two groups in the coefficient of 0.15. The dendrogram obtained contained two main groups, with SL-2-6 genotype is an effective out-group. The origin of the genotypes was not always related to the cluster. The highest heritability was found for plant height. Negative inbreeding depression was revealed by majority of the F2 population. Construction of diversity can be done using morpho-agronomic and the use of these will allow a quick selection. The result result indicated that F2 generation showed diversity and the strong potential usage for further advanced in low glycaemic index and fine grain rice breeding.
