This two year of study was conducted during 2017–18 and 2018-19 to assess the influence of Conservation tillage practices (CTPs) and precision nitrogen management practices (PNM) on wheat genotype DBW-17 in sandy loam soil of Modipuram, Meerut, Uttar Pradesh. The experiment comprising four crop establishment methods (CEMs) [(Zero tillage (ZT), reduced tillage (RT), furrow irrigation raised beds (FIRB), conventional tillage (CT)] in the main plot and five precision nitrogen management options [N 80:20, N 33:33:33, N 80 – LCC, N 50:50 and farmers fertilization practice in sub-plot and laid out in split-plot design with three replications. The results of the current experiment showed that the use of a furrow irrigated raised bed system (FIRB) and the application of nutrients like N 80-LCC for wheat seemed to be the best combination for achieving higher crop growth characteristics and yield under the north-western plain zone of Uttar Pradesh. So, during two years of study, it was confirmed that FIRB and N 80- LCC based practices on wheat fertilizer demand could significantly increase efficiency and achieve a higher yield level, which provides a theoretical basis for the realization of the synergistic combination.
The study curried out to study the chemical composition of tagette essential oil and evaluate the insecticidal activities of tagette oil against two major stored product insects Tribolium castaneum and Rhyzopertha dominica. The study indicated that, Dihydrotagetone was the main component in tagette oil with 28.85 % percentage of total oil followed by Cis- Ocimene with 26.91%. For T. castaneum the highest concentration 0.24 mg/cm2 had the highest repellent effect with 87.5% repellency after over the 24 h duration. All tested concentrations had a repellent effect on R. dominica the repellency percentage was increased with increasing exposure period and concentrations. tagette essential oil showed fumigant toxicity against R. dominica and T.castaneum. However, R. domenica was considerably more susceptible than T. castaneum. For R. dominica after 3 h tagette essential oil had fumigant effect, with LC50 value 0.26 mg/cm3 while after 6 h tested oil had fumigant effect with LC50 value 0.17 mg/cm3. While after 48 h T. minuta oil had the fumigant effect with LC50 value 0.48 mg/cm3. tagette oil had contact effect at all exposure periods of exposure against T. castaneum with LC50 of (7942.9, 3375.0 and 2967.7 mg/kg) after 24, 48 and 72 h of exposure, respectively. Data also showed that tested essential oil had contact effect on adults of R. dominica with LC50 of (820.7 and 665.5 mg/kg) after 24 and 48 h of exposure, respectively.
The present investigation was carried out at Thirumaraiyur village, Sattankulam taluk, Thoothukudi district to study the effect of organic amendments with recommended dose of fertilizers on growth and yield of watermelon and physic-chemical properties of Theri soil (red sand dunes) during the year 2018 and 2019. The experiment was laid out in Randomized Block Design with Factorial concept (FRBD). In all there were three factors as organic amendments with 6 treatment combinations for each factor, which were assigned at random in each plots with three replications. The recommended dose of fertilizers in treatments were two levels as 75 and 100 per cent. Among the treatment combinations, the tank silt application @ 100 t ha-1 with 100 per cent recommended fertilizer as 200:100:100 kg of NPK ha-1 through fertigation at 7 days interval (A1N5) produced maximum number of branches (10.67), longest vine (362.0 cm), number of fruits plant-1 (2.57), weight of fruit (5.27 kg), fruit yield (68.77 t ha-1), gross return ( 4,09,320/ha), B:C ratio (2.45) and improved the physic-chemical properties viz., particle density (2.45 Mg m-3), bulk density (1.31 Mg m-3), per cent pore space (48.33%), pH (6.58), EC (0.35 dSm-1) and organic carbon content (0.52%).
Site Specific Nutrient Management is a system for maximum yields in field crops. Nutrient Management Zones were developed for castor crop (Ricinus communis L.) in Inceptisols under semi-arid regions of India. Grids of 15 x 15 m were made in one hectare and soil samples were collected from each grid and were analysed for soil characteristics and all available nutrients. Based on analytical data the geo-statistical analysis varoni maps and different models like K-Bessel for pH, nitrogen, phosphorous and potassium, J-Bessel for E.C. Circular for sulphur, Spherical for zinc, Rational Quadratic for copper and manganese, Exponential for iron and Penta Spherical for boron with weak, moderate and strong spatial dependency were developed. The castor yield data was compared in nutrient management zones with farmers practice (FP) and recommended dose of fertilizers (RDF). The variable rates of fertilizers used by adopting STCR equation in SSNM was 92, 53, 15, 40 & 25 kg of N,P,K,S and Zn/ ha and 100, 40, 30 and 80, 40, 30 kg of N, P, K in farmers practice and RDF plots. The yields obtained with SSNM practice was 28 q/ha and 15 and 13 q/ha with RDF and farmer’s practice treatments respectively.
Mentha piperita L. (Peppermint) is a perennial glabrous and strongly scented herb belonging to family Lamiaceae. The plant is aromatic, stimulant and used for allaying nausea, headache and vomiting. Its oil is one of the most popular widely used essential oils in food products, cosmetics, pharmaceuticals, dental preparations, mouthwashes, soaps and alcoholic liquors. The study was carried out in Community Science College and Research Institute, Madurai. The phytochemicals such as alkaloids, tannins, phenols, flavonoids and steroids were analyzed in the pepper mint leaf extraction. The different solvents such as ethanol, methanol, chloroform, hexane and distilled water were used for extraction of leaves. Among the solvents hexane and chloroform extracts had more amounts of alkaloids was present. Followed by other solvents such methanol, ethanol and distilled water had some amounts of alkaloids. The total phenol content of fresh sample (693.3 mg) is higher than the powder sample (666.6 mg) and the tannin content of fresh sample is higher (866 mg) than the powder sample (543 mg). The antioxidant activity of fresh sample (8.1% in ml leaf concentration) and powder sample (22%) were analyzed. Radical scavenging activity antioxidant activity of powder sample is higher than the fresh sample.
