Rice blast (Pyricularia oryzae) is the most destructive disease of rice in Jammu & Kashmir. The variability status of P. oryzae was not studied in Jammu region, although many studies had been done in the Kashmir region, therefore the present study is first study which aimed at determining the cultural variability in the rice blast isolates of the Jammu region. In this research, leaf blast samples were collected from the rice growing areas of five districts of Jammu division and variability among 30 isolates of Pyricularia oryzae was studied with respect to cultural traits. The colony colour of thirty isolates collected during the survey were off white to greyish black, with circular or irregular margins and flattened to raised growth pattern. On the basis of colony growth pattern, margin and colour, the isolates were categories into 6 groups (A, B, C, D, E and F). All thirty isolates exhibited excellent variability in respect of colony growth pattern, margins and colony colour.
Sesame root and stem rot incited by Macrophomina phaseolina is polyphagous a soil borne and phytopathogenic fungus having a wide host range of about 500 cultivated and wild plant species worldwide. In the present study efforts were made to find out the sources of promising breeding cultivar/varieties to root and stem rot of sesame. In present investigation comprised of 314 cultivars of sesame including two local checks GT-10(resistant) and VRI-1(Susceptible) were used for rapid screened by sick pot method against Root and stem rot against M.phaseolina. Among 314 cultivars results were observed seven cultivars were recorded between 15-20 per cent and 35 cultivars recorded between 21-30 percent root and stem rot incidence.
This study aimed at assessing the level of livelihood diversification and its determinants in the Uttarakhand hills using the Simpson diversification index and a multiple linear regression model from the data obtained from 200 sample farmers chosen through a multistage random sampling technique. The results indicated that there was 100 per cent engagement of households in agricultural activities, yet the proportion of average income derived from them was only 4.78 per cent. The value of the diversification index indicated that about 19 per cent of the sample households belonged to low, 49.50 per cent to moderate, and 31.50 per cent of households belonged to a high level of livelihood diversification. Further, the results of the multivariate regression equation indicated that household structure, dependency ratio, education of household, organisation membership, and training had positive effects, while age of household head and farm size showed negative effects on livelihood diversification. As the soil and topography in the state are not suitable for mono-cropping, mixed agricultural practises need to be adopted. Small scale industries, cottage industries, and tourism should be developed and have diverse skill development training programmes.
Germination increases the bioavailability of nutrients and sprouts are a good source of vitamins and minerals. Seeds of three mung bean varieties (SGC-16, SGC-20 and IPM-02-3) of Assam were sprouted at 24, 48, 72 and 96 h under dark at 25±2°C. Significant increase in moisture content, crude protein, crude fibre and ash contents, while crude fat, starch and carbohydrate content significantly decreased during the sprouting period. Mineral contents (Na, K, P, Ca, Mg, Fe, Zn, and Cu), vitamin C, niacin significantly increased during the sprouting period. Thiamine increased up to 72 h and riboflavin increased up to 48 h and then both showed decreasing trend. Antinutritional factors like phytic acid and tannin significantly decreased while, in vitro protein digestibility significantly increased during sprouting periods. The varieties SGC-20 and SGC-16 are nutritionally superior over the variety IPM-02-3 which can be recommended for use in breeding as sprout varieties.
Information about the soil physical and structural quality of diverse land-uses (LUS) is essential for the sustainable development, utilization, and protection of natural resource viz. soil in plateau of Meghalaya. In this study, depth wise (0-0.15 m and 0.16-0.30 m) particle size distribution, bulk density (BD), particle density (PD), maximum water holding capacity (MWHC), aggregated (Silt+Clay), structural stability index (St), mean weight diameter (MWD) and geometric mean weight diameter (GMD) were analyzed under Jhum-System, Mixed-Forest, Pine-Forest, Rice-Potato, Rice-Cole Crop, Upland Rice-Monocrop, Lowland Rice-Monocrop, Upland Pineapple-System and Upland Broom-System suited in Upper Shillong, East Khasi Hills, Meghalaya. The results showed alteration in sand, silt, clay, BD, PD, MWHC, AG (Silt+Clay), St, MWD and GMD in relation to diverse land uses (LUS). The Mixed-Forest soils had the lowest BD (1.15 Mg/m3), at surface and highest in Rice-Potato (1.39 Mg/m3). The mean content of PD and MWHC in all types LUS were varies between 2.40-2.75 (Mg/m3) and 45.04-58.37%, respectively whereas highest PD and MWHC was recorded in Jhum-System and upland Broom-System, respectively. The BD of different LUS was increases with depth and MWHC decreases with depth. The ranges of AG (Silt+Clay), MWD, GMD and St were ranging from 67.19-75.98%, 1.08-2.42 (mm), 0.61-1.25 (mm) and 3.81-6.87%, while highest and lowest value were observed in all LUS in surface soil Mixed-Forest and Rice-Cole Crop. On an average in the subsurface soil all soil aggregate parameters were decline in different LUS. Correlation between aggregating elements and aggregate stability parameters with MWD viz. GMD and St were positively correlated with MWD @ 0.01 per cent level (2-tailed) under different LUS in 0-15 cm whereas sand and clay have no correlation with MWD. Relationship between silt, AG (Silt+Clay) with sand had strongly negative correlation, while with St has strongly positive correlation @ 99 per cent confidence level.
