    The present investigation entitled “Effect of different sowing methods and manuring on growth, bio-chemical traits and yield of Ashwagandha (Withania somnifera (L.) Dunal).” was carried out at instructional cum research farm, Indira Gandhi Krishi Vishwavidyalaya (IGKV), Raipur (Chhattisgarh) during Rabi season of 2017-2018. The specific objectives are effect of various methods of sowing on growth parameters and biochemical traits of Ashwagandha, effect of organic sources of nutrients on yield and its attributes of Ashwagandha, correlation between growth parameters and yield attributes of Ashwagandha. The experiment was laid out in split plot design with three replications. The whole treatments were divided into main plot i.e. flat bed, ridge and furrow method and sub plot i.e. control, FYM @ 10 t ha-1 , FYM @ 15 t ha-1 , Vermicompost @ 5 t ha-1, Vermicompost @ 7.5 t ha-1 , Castor cake 1.5 t ha-1 , Castor cake 2.5 t ha-1, RDF(NPK @ 40:60:20 kg ha-1). The soil of the experimental field was clay loam in texture and with medium in available nitrogen, phosphorus and high in available potassium content. Ashwagandha variety GAA-1 was sown on 30th October 2017 and harvested on 05th June 2018.

    (Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.), 2019) Banjare, Bhumika; Tiwari, S. P.; Guhey, Arti; Verma, L. S.; Saxena, Ravi R.
    The present experiment was conducted in Department of Plant Physiology, Agricultural Biochemistry and Medicinal and Aromatic Plant in 2018-19. Experiment entitled “Impact of different growing media on physiological and morphological growth of orchid (Dendrobium L.)” in four different media Cocopit, Sawdust, Vermicompost and Charcoal and growth regulator. Four treatment of plant growth substances viz, GA3 @150 ppm, Kinetin @ 100 ppm and AgNO3 @30 ppm were applied along with control (Water spray) to elucidate the effect of plant growth substances on flower quality and vase life of flower, post harvest studies with holding solution of GA3 + 5% Sucrose, Kinetin + 5% Sucrose, AgNO3+5% Sucrose along with control were tried to increase the vase life of cut flower. Among the growth media tested Charcoal media was found to be the best for plant height (45 cm) at flowering stage, Number of leaves (6.33), Number of shoot (4.33), Shoot girth (4.1 cm), Root length (32.46 cm), Leaf area (21.68 cm2), SPAD Value (53.54), Spike length (54.23 cm), Spike girth (2.3 cm), Number of floret per spike (6.0). The treatment T3 (Vermicompost) recorded best for Number of new shoot (2.33), Internode length (7.7 cm), Number of internode per shoot (6.33). The treatment T2 (Sawdust) registered the lowest values for Plant height (40.66 cm) at flowering stage, Number of leaves (4.00), Shoot girth (3.03 cm), Number of internode per shoot (4.66), Root length (23.23 cm). Among different growth substances, the minimum day for flower bud initiation was recorded in P3, Kinetin@100 ppm (23.25 days), P3, Kinetin@100 ppm was found to be best for spike girth (1.90 cm), Floret size (41.6 cm2), Longevity of flower (75.08 days). Treatment T3, was found to be effective for number of spike (2.1), number of floret (5.41), dry matter production (9.35 g). The interaction between Charcoal media and Kinetin@100ppm was found best for Flower bud inititiation (19.66 days), Number of spike (2.6), size of flower (42.26 cm) This second experiment was laid out in Factorial Completely Randomized Design. In the post harvest study, among the holding solution tried, AgNO3 was found to be best for increase the vase life of cut flower (27 days) also reduced the physiological loss of weight (91 per cent). Control (Pure water) was recorded minimum days for increase the vase life (19.33 days).

    PHYSIOLOGICAL EVALUATION OF RICE (Oryza sativa L.) GENOTYPES FOR NITROGEN USE EFFICIENCY UNDER DIFFERENT NITROGEN LEVELS
    (Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.), 2019) Rai, Sudhanshu; Kuruwanshi, V. B.; Guhey, Arti; Porte, S. S.; Saxena, R. R.
    The present investigation entitled “Physiological evaluation of rice (Oryza sativa L.) genotypes for nitrogen use efficiency under different nitrogen levels” was carried out at Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during kharif 2018. The rice productivity and food production is influenced by nitrogen. The two major constraint in enhancing the rice production are the poor utilization and grain yield which is depend on absorbed nitrogen efficiency rates. Since, nitrogen fertilizer is expensive input and its usage varies in different ways, so, it is required new varieties to determine their physiology and yield under variable nitrogen rates. Nitrogen utilization efficiency is also a complex phenomenon defined as an increase in the yield of grains that is produced per unit of nitrogen. The increasing nitrogen use efficiency is imperative to future sustainable agriculture. Therefore, the present study was conducted to develop nitrogen use efficient varieties. The whole study was arranged in split plot design with three replications during kharif, 2018. The 13 rice genotypes were tested with three recommended dose of nitrogen i.e. 0% RDN Control (T1), 50% RDN (T2) and 100% RDN (T3). The 12 tested rice genotypes material was collected from DRR, Hyderabad and one check variety (Poornima) from IGKV, Raipur. The fertilizers were applied as per the recommended doses (0:45:60, 50:45:60 and 100:45:60 kg ha-1) N, P, K applied in the form of DAP and first 50% dose of N was applied at 10-15 DAT, second 25% dose at active tillering stage and third dose was applied at panicle initiation stage (PI). The recommended dose of P and K fertilizers (45 P2O5, 60 K2O kg/ha) applied as basal dose. The observations such as. plant height (cm) at tillering and flowering stage, number of tillers per hill, number of productive tillers per hill, total dry matter accumulation at flowering and maturity stage (g/m2), leaf area index (LAI), flag leaf area (cm2) and biochemical parameters i.e. Chlorophyll content (SPAD) at flowering, starch content (%), protein content (%), nitrogen content in leaves + stem and grains (%), nutrient uptake (nitrogen g/m2) and yield component such as number of panicle per m2, no. of spikelet per m2, test weight (1000 seed), grain yield (g/m2), harvest index (%) and nitrogen use efficiency (NUE g yield/g N) were recorded under different nitrogen level. The morpho-physiological parameters like plant height (cm) at tillering and flowering stage, number of tillers per hill, productive tillers per hill, total dry matter at different growth stages (g/m2), leaf area index (LAI), flag leaf area (cm2) were found significantly influenced by different nitrogen level and performed better under treated with 100% RDN. Plant growth is enhanced due to increasing nitrogen content and the possible reason behind the fact is that the meristematic cells number and size increased with application of nitrogen which is responsible for the emergence of new sprouts. It is also well known that the cytokinin levels was enhanced that affects the extensibility of cell wall by application of N. Therefore, it is reasonable to speculate that the regeneration and division of new cells directly or indirectly involved due to nitrogen as well as the production of new tissues which in turn were responsible for the growth in growth characteristics. The biochemical parameters viz., total chlorophyll content (SPAD), starch content (%), protein content (%), nitrogen content in leaves, stem and grains (%), and nutrient uptake (nitrogen g/m2) were found positively correlated to the cumulative doses of nitrogen supplies. The yield components like number of panicle per m2, number of spikelet per m2, grain test weight (1000 seed) and grain yield (g/m2) has been improved due to efficient uptake and absorption of other elements along with nitrogen that translocated the dry matter from area of source to sink to increases the production. An application of nitrogen enhanced in yield attributing parameters which may be credited to the improved vegetative growth and aiding the photosynthesis, thus the organic food materials translocated towards reproductive parts which improve and enhanced the panicle formation with fertile grains. The nitrogen use efficiency (NUE) is important factor to find out the fate of nitrogen supplies through which efficient absorption or utilization by the plant is improving maximum economic yield. Therefore, on the basis of all above important traits, genotype Rasi under (T3 100% RDN), Rasi x Jaya/2 under (T2 50% RDN) and Sampada x Jaya/3 under control (T1 0% RDN) performed better and exhibited maximum grains yield (g/m2) as compared to all the tested genotypes. The maximum nitrogen use efficiency (NUE g/g N) was recorded in genotype Rasi followed byVaradhan among all the treated rice genotypes.
