Abstract:
Mosquito, the infamous vector organism, is responsible for outbreaks of several deadly epidemics. Semiochemicals or pheromones and some other compounds released from several plants and animals have ability to attract mosquitoes. Heneicosane is one of such compounds reported from some plants that attracts mosquitoes, especially Aedes spp. (vector of dengue). Through our experiment based on GC-MS analysis, we report that leaf of Dendrobium candidum Wall. ex Lindl, a local orchid of Darjeeling Himalayas, is a source of heneicosane along with several other semiochemicals and odorants that can target mosquitoes. Interestingly, the orchid sample has revealed a number of components having insecticidal activities against mosquitoes which can have made this orchid a complete mosquito-bait. This research invites interest for Dendrobium candidum as a mosquito attractant and killer. For this unique property, we recommend this orchid leaf extract as a bait for dengue vector Aedes mosquito.

Abstract:
Lady’sfinger Abelmoschus esculentus (L.) Moench is an annual kharif vegetable crop belongs to the family Malvaceae. This crop is cultivated in various parts of tropical and sub-tropical areas of the world. In West Bengal, India it is cultivated in a commercial scale but its pest complex is very high which limit its production. Contribution of whitefly (Bemisia tabaci) and aphid (Aphis gossypii) as sucking pest in this case is of great importance. Three doses of dinotefuron 20 SG (@ 20, 30 and 40 a.i. g /ha) two doses of imidacloprid 70 WG (@ 21 and 24.5 a.i. g /ha) and two doses of fipronil 5% SC (@ 25 and 37.5 a.i. g /ha) were applied to control whitefly and aphid. From overall observation it was revealed that dinotefuron 20 SG @ 40 g a.i./ha, fipronil 5% SC @ 37.5 g a.i./ha and imidacloprod 70 WG @ 24.5 g a.i/ha provided best suppression of whitefly (83.46 %, 82.59 % and 68.94 % white fly population suppression respectively) and aphid (79.02 %, 76.96 % and 70.46 % aphid population suppression respectively). These insecticides may be recommended for farmers use to control sucking pest.

Abstract:
Fourier transform infrared (FTIR) spectroscopy method was used for the analysis of phytochemicals present in Tabebuia rosea seed oil and its biodiesel. FT-IR spectra of Tabebuia rosea seed oil and its biodiesel have been recorded in the region 2925 - 604 Cm-1. FT-IR is a vibrational spectroscopy that records absorptions of IR light by chemical bonds in all molecules including polymers. The different frequency ranges and their different functional groups were analyzed during the study period. FT-IR spectroscopy of the Tabebuia rosea seed oil reveals diverse functional groups and there by confirmed the possible presence of phytochemicals such as Terpenoids, Steriods, Flavonoids, Tannins, Coumarins, etc.

Abstract:
The Present study was undertaken in Dharni tahsil of Maharashtra State during the year 2017-19. This area is also popularly known as Melgha t region, which is located in the physiographic unit i.e. eroded valley with the elevation of 316 - 642 meters above mean sea level. Korku is the dominant tribes inhabited in this region and have small land holding adjoining to forest. The data on natural resources such as climate, soil-site characteristics and land use system aspect were collected. Twenty four spot were selected on different land use system based on single crop, double crop, scrub land and forestland fallow land. Dharni Tahasil received an annual rainfall ranges from 1350-1450 mm. Temperature varies from 34°C in summer to 21°C in winter. The soils were developed on weathered basalt. The soils were very gently to steep sloping with moderately to very severe erosion. The soils are dark reddish brown to dark brown with shallow to medium deep in depth and structure was angular blocky to sub angular blocky.

Abstract:
The population buildup of yellow stem borer, Scirpophaga incertulas was experimented during Kharif, 2018 and 2019 at thr CRC farm of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, U.P. The infestation of stem borer was recorded on variety Pusa Basmati-1 at weekly intervals from 32nd standard week and continued till the 43rd standard week and 33rd standard week and continued till the 43rd standard week during Kharif 2018 and 2019, respectively. The infestation of stem borer recorded as dead hearts /white ear heads and increased from third week of August and reached its peak (13.40%) in 41st standard week (Second week of October) and reached its peak (12.35%) in 36th standard week (second week of September) during Kharif 2018 and 2019, respectively.

Abstract:
A field experiment was conducted for two years by taking four crops to study the “Liming practice impact on post-harvest soil properties for Maize-Greengram cropping system in Acid soil of Odisha” in the village MV-13 in Malkangiri district of Odisha during both Kharif and Rabi in the year 2017 and 2018 .The soil was ameliorated with three different sources of liming materials (paper mill sludge, Stromatolyte and Calcium Silicate @ 0.2 LR) added with soil test based dose/nutrient expert with FYM. Results indicated the post-harvest soil properties indicated that The two years of cropping harvest of four crops made soil more acidic which was not received any lime application in different POPs. Integrated use of liming materials with FYM and fertilizers (STD/NE) maintaining the available macro and micro nutrients where was decline occurs in without liming practices. The continuous application of only fertilizers decline the nutrient status and creats acidity in post harvest soil. The application of liming practice with NE gives better results compare to the STD alone.

Abstract:
Forty cultivars of durum wheat were evaluated for yield and yield contributing traits in randomized block design (RBD) with three replications to determine the association between yield and yield attributing traits through correlation and path analysis. Significant genotypic differences were observed for all the 12 quantitative traits studied, indicating presence of considerable amount of variation among genotypes. The correlation coefficient analysis showed significant and positive correlation of grain yield per plant with biological yield per plant, harvest index, number of productive tillers per plant, number of grains per main spike and grain weight per main spike. Significant and positive correlations were observed for number of productive tillers per plant with biological yield per plant; number of grains per main spike with grain weight per main spike and harvest index; grain weight per main spike with harvest index and 100-grain weight; harvest index with 100-grain weight. The genotypic path coefficient analysis revealed that the biological yield per plant and harvest index exhibited high and positive direct effects on grain yield per plant. Biological yield per plant, grain weight per main spike, number of grains per main spike, number of productive tillers per plant and harvest index merits special attention in formulating selection strategy in durum wheat for developing high yielding varieties.
