The construction of a road, directly and indirectly, impacts on the ecosystems where the road is built. Highways passing through national reserves/wildlife sanctuaries have an adverse impact on wild animals. The present survey was conducted to estimate the road kills on the state highways passing through the Nilgiri north territorial forest division (19km) and Mudumalai Tiger Reserve (15km) in Sigur Plateau, Tamil Nadu, India. The road kills were monitored three times a month between July 2013 and December 2013 (six months) and a total of 176 road kills belonging to 30 species were recorded. Reptiles were the most affected taxa (39%), followed by mammals (33%) and birds (21%). Amphibians were least affected by vehicular traffic and comprised 7% of the total kills. According to road stretch category, the overall road kill was N=135 in the forested area and N=41 in human habitations. A total of 812 food materials were encounterd 612km with average of 1.32 food materials / km. Conservation and management implications are essential to prevent the local extinction of wildlife.
Background: Pulses play an important role in Indian agriculture and they are the rich sources of protein. Redgram is an essential food legume, mostly cultivated under rainfed condition in India. Due to increasing population the demand of pulses is increased; hence the redgram productivity has to be increased to meet out the requirement. To overcome this problem an investigation was carried out to study the effect of crop geometry, modified canopy architecture and 1% PPFM application on morpho-physiological and biochemical responses of rainfed redgram during north-east monsoon season.
Methods: The treatments comprised of varied crop geometries viz, broad casting (farmer’s practice), high density planting at 30 × 30 cm and recommended spacing of 60 × 30 cm; modified canopy architectures viz. nipping of primary branches at 45 and 60 days after the receipt of soaking rain and foliar application of 1% PPFM spray at 50% flowering to avoid the moisture stress. Result: The results revealed that sowing at 60 × 30 cm spacing with nipping at 45th day recorded significantly higher seed yield and protein yield of redgram in rainfed condition. Further, nipping at 45th day showed higher level of relative water content (51.6%) associated with lower level of proline (26.61 mg g-1).
A study was undertaken at Agricultural College & Research Institute, Coimbatore during Summer and Kharif seasons of 1994 to investigate the effect of three levels of plant densities with various weed management methods in Soybean. The results revealed that the weed density significantly reduced in the higher plant density of 6.66 lakh plants ha in both the seasons. Among the weed management methods, pre-emergence application of alachlor 1.25 kg ha-1 hand weeding (40 DAS) and hand weeding twice (20 and 40 DAS after sowing) have considerably reduced the weed population and enhanced the grain yield. However, hand weeding twice had exhibited similar effect as that of alachlor 1.25 kg ha-1 + hand weeding (40 DAS) in suppressing the weed population at 40 DAS. The yield attributes like number of pods per plant, number of seeds per pod and test weight of the seeds were greatly influenced at lowest plant density of 3.33 lakh plants ha-1, however it was comparable with 4.44 lakh plants ha in registering the test weight. There was significant increase in yield of the crop under 4.44 lakh plants ha-1.
