Migration from rural areas to urban areas has become an inevitable phenomenon during the last two decades. Industrialization of urban areas, investment opportunities, growing service industry, food security, better health infrastructure, education facilities and growing aspirations are some of the factors responsible for the migration in India. Agriculture plays an important role in rural economy but this sector is not lucrative and as a result rural farming youths are currently more interested in going to cities for acquiring necessary skills for getting jobs in private sector rather than working in fields. This study was conducted in Hisar and Bhiwani districts of Haryana and a sample size of 196 rural youths (96 fully migrated + 96 partially migrated) were selected for the study. Findings revealed that unstable income, lesser employment, repeated crop failures were the push factors responsible for migration of rural youths. Higher wages, better jobs and better standard of livings in cities were the major pull factors motivating rural youths to migrate towards cities. Further, socio-economic & psychological variables such as age, education, farm size, non-farm skills, proximity to town, economic motivation, risk orientation, self-reliance & self confidence have positive and significant relationship with migration behaviour of rural youth whereas, income expectancy, comfort expectancy, stimulation expectancy and affiliation expectancy have significant but negative relationship with migration behaviour. Also, regression analysis showed that seventeen independent variables selected for the study could explain 59.40 per cent variation in the migration behaviour of rural youth.
Performance of Kinnow mandarin scion was assessed on eight different rootstocks in the rainfed condition of Jammu subtropics, Jammu & Kashmir (UT) of India to expand its cultivation and fruit availability for rural areas peoples. During investigation it was observed that Kinnow mandarin scion was attained the maximum plant highest (275cm), No of fruits (196.00), total yield (27.44kg/plant ), maximum TSS (11.33oBrix), total sugar (7.95%), reducing sugar (5.66%), non-reducing sugar (2.29%), ascorbic acid (25.25mg/100g) and lower content of acidity content (0.83%) was also obtained on jattikhatti rootstock, whereas the maximum plant spread [N-S=210.00 cm] and [E-W= 205.00 cm], fruit weight (145.00g), fruit length (5.72cm), fruit breath (6.85cm), No. of segment (11.66) and minimum no. of seed (20.00) and highest fruit juice content (55.89ml) was registered in Gargal rootstock. The highest peel weight (53.33g) and Peel thickness (2.40mm) was reported in Rangpur lime rootstock. Overall, it was observed that both Jattikhatti and Gargal can be considered a best rootstock in Jammu region to extend the Kinnow production and superior quality fruits.
Breeding for salinity tolerance crop varieties in oil seed crop like Taramira (Eruca sativa Mill.) is paramount important for sustainable oilseed production as well as self-sufficiency of Indian nation. This study was aimed to assess the effect of salinity on 8 different genotypes of taramira at seedling stage for 12 traits at seedling stage. The study revealed that the genotypes RTM-1351 and RTM-1355 showed tolerance and provided overall high stability results in higher salinity concentration. These genotypes might be useful for further invigorating the breeding programme and to broaden the genetic base of existing varieties of taramira crop to increase productivity.
Soil salinity is the major factor responsible for poor germination, growth and development leading to reduction in crop yield. The present study was conducted with aim to evaluate 10 genotypes of taramira at 4 levels of salinity concentrations. Observations on12 parameters were recorded including germination percentage and other seedling traits. The two genotypes RTM-1351 and RTM-1355 exhibited significant variation among all the traits and the levels of salinity concentrations. High heritability coupled with high genetic advance was observed for root fresh weight, such trait can be exploited for selection criteria for developing salinity tolerance varieties.
The experiment was conducted on farm of Rajasthan Agricultural Research Institute (RARI), Durgapura, Jaipur (Raj.) to study the Effect of different liquid biofertilizers and fertility levels on growth, yield and quality of cluster bean (cymopsis tetragonoloba). The test crops were raised on field during kharif-2018 and 2019. The experiment was laid out in factorial randomized block design (FRBD). The treatment details of experiment comprised with two factors eight treatment of liquid biofertilizer: control (L0), Rhizobium (L 1), PSB (L2), KMB (L 3), SSB (L 4), Rhizobium + PSB (L 5), Rhizobium + PSB+ KMB (L 6) and Rhizobium + PSB+ KMB + SSB (L 7) and (2) three treatment of fertility levels: 100 % recommended dose of fertilizers (F1),75% RDF (F2) and 50 % RDF (F3) and total number of treatment were 24. The maximum increase in growth parameters viz., plant height, number of branches per plant, leaf area and dry matter accumulation, effective root nodules per plant, nodules dry weight, CGR, RGR and NAR observed in 100 % RDF (F1) with Rhizobium + PSB+ KMB + SSB (L 7) but the combination of 75% RDF with Rhizobium + PSB+ KMB + SSB (L 7) found the similar effect with 100% RDF with Rhizobium + PSB+ KMB + SSB (L 7). However, the combined treatment of 75% RDF with Rhizobium + PSB+ KMB + SSB (L 7) noticed significantly superior than other treatment.
