 Field experiments were conducted at ICAR - Indian Institute of Horticultural Research, Bengaluru during Kharif season of 2015 and 2016 with nine treatments and three replications in a randomized block design to find out the effects of integrated nutrient management on Quantity and Quality of essential oil of basil (Ocimum basilicum) . The results revealed that combined application of recommended FYM (10 t ha-1) and NPK (160:80:80 kg ha-1) registered the highest oil yield in the main crop (211.94, 187.46 l ha-1) and in ratoon (144.36, 70.81 l ha-1) during 2015, 2016, respectively. For oil quality, the main constituents of basil essential oil have been reported and the result showed that chemical compositions of the essential oil for sweet basil were affected by fertilizers in the maincrop and ratoon during two years of the experiment. In general, application of NPK (160:80:80 kg ha-1) + FYM (10 t ha-1) i.e., T9 recorded the best quality. The results obtainedfrom this study demonstrated that integrated nutrient management can maximize nutrient absorption as a result of increased soil fertility which reflected on oil yield and quality.

<p><span>A field experiment was conducted to evaluate yield and some qualitative characteristics of four cultivars of sweet basil treated with different levels of nitrogen fertilizer. The experiments were located on the Agricultural Research Station of Khorramabad, Iran, during the 2016-2017 growing season. Treatments were arranged in factorial split-plot-in time in randomized complete block design with three replications. Experimental treatments were four cultivars of sweet basil (<em>Ocimum basilicum</em> ‘Italian Large Leaf’, <em>O. basilicum</em> ‘Mobarakeh’, <em>O. basilicum</em> ‘Cinnamon’ and <em>O. basilicum </em>‘Thai’), three levels of nitrogen fertilizer (0, 100 and 200 kg ha<sup>-1</sup> urea) and three harvests. The highest total dry mass (3482.4 kg ha<sup>-1</sup>) was related to ‘Italian Large Leaf’ with the application of 200 kg ha<sup>-1</sup> urea at the second harvest. The maximum (26.79 kg ha<sup>-1</sup>) essential oil yield belonged to 100 kg ha<sup>-1 </sup>urea. The highest concentrations of main constituents of essential oil, except methyl chavicol, 1,8-cineole and methyl cinnamate were obtained by control (without nitrogen fertilizer). Italian Large Leaf cultivar and application of 100 kg ha<sup>-1</sup> urea are recommended to access an acceptable agricultural yield and essential oil yield in sweet basil under the environmental condition similar to Khorramabad</span></p>

The integrated use of chemical and organic fertilizers can help in sustainable and environmentally sound nutrient management of soils. A study was conducted in the farmer’s field of Godaghari, Rajshahi from February to May 2012 to investigate the effect of integrated nutrient management on nutrient uptake by rice cv. NERICA 10 and economization of inputs. Six treatments viz. T1 = Control, T2 = RFD for MYG + cowdung @ 5 t ha-1, T3 = RFD for HYG, T4 = RFD for HYG + cowdung @ 5 t ha-1, T5 = RFD for HYG + cowdung @ 5 t ha-1 based on IPNS, and T6 = RFD for HYG + 10% excess fertilizer of HYG were used. The experiment was laid out in a randomized complete block design with three replications. Results showed that the uptake of N, P, K, S, Ca and Mg by both grain and straw of rice were statistically significant due to use of integrated nutrient management. The highest nutrient uptake was recorded from the treatment T5 and the lowest value was obtained from control. Combined application of cowdung @ 5 t ha-1 along with recommended chemical fertilizers based on IPNS was more economic compared to other treatments because maximum benefit cost ratio was calculated from this treatment. The overall results suggest that integrated nutrient management can be used as an alternate option of chemical fertilization to achieve maximum yield, nutrient uptake and cost of return for rice cv.

To improve essential oil quality, especially to reserve the thermal instability of compounds, supercritical CO2 extraction (SFE) was applied to recover essential oil from Cymbopogon citronella leaves. A response surface methodology was applied to optimize the extraction process. The highest essential oil yield was predicted at extraction time 120  min, extraction pressure 25  MPa, extraction temperature 35°C, and CO2 flow 18  L/h for the SFE processing. Under these experimental conditions, the mean essential oil yield is 4.40%. In addition, the chemical compositions of SFE were compared with those obtained by hydrodistillation extraction (HD). There were 41 compounds obtained of SFE, while 35 compounds of HD. Alcohols and aldehydes were the main compositions in the essential oils. Furthermore, the antioxidant activities and antimicrobial of essential oils obtained by HD and the evaluated condition of SFE were compared. Results showed that the antioxidant activities of SFE oil are better than those of HD. Minimum inhibitory concentrations (MICs) were determined by the microdilution method. Essential oil obtained from SFE and HD exhibited a significant antimicrobial activity against all tested microorganisms. It is confirmed that the SFE method can be an alternative processing method to extract essential oils from Cymbopogon citronella leaves.

A field experiment was conducted during rabi 2007-08 to 2008-09 at Uttar Banga Krishi Viswavidyalaya, Cooch Behar situated at sub-Himalayan plains popularly known as terai region of West Bengal, India to study the productivity of yellow sarson under different nutrient management practices and seed priming methods. The experiment was laid out in a factorial randomized block design with eight nutrient management practices and three seed priming methods. The results showed marked improvement in yield components, productivity and economics of yellow sarson due to integrated nutrient management and seed priming methods. Significantly highest seed yield (1374 kg ha-1) was recorded with combination comprising FYM + Azotobacter + PSB and 75% of the recommended fertilizers. The integrated nutrient management practice also had greater impact in production economics, sustenance in soil fertility and enrichment of soil nutrients. The crop receiving plant nutrients only from chemical sources showed poor productivity leading to less remuneration. Higher seed oil content (41.8% and 42.2%) was obtained with the application of 100% of the recommended dose (60:30:30 kg N:P2O5:K2O kg ha-1) along with sulphur (20 kg ha-1) but the oil yield was not impressive due to poor seed yield. Pre-sowing soaking of seeds with 100 ppm KH2PO4 also showed improvement in yield components, productivity and oil yield of the yellow sarson crop compared to seeds soaked with 100 ppm Na2HPO4 and water. Net returns and return/rupee invested were higher when the yellow sarson seeds were soaked with 100 ppm KH2PO4 over the other soaking methods. Variations in residual fertility were not discernible due to seed soaking. DOI: http://dx.doi.org/10.3329/sja.v12i1.21117 SAARC J. Agri., 12(1): 106-116 (2014)

Background: Sesamum indicum L. is a tropical and subtropical plant cultivated for seed purpose, which yields about 50% high quality edible oil with 65% of the seeds being used for oil extraction and 35% for consumption purpose. The seeds have outstanding amounts of oil and consists of extensive root system that makes it very tolerant of drought.Methods: A field experiment entitled “Effect of planting density and Integrated Nutrient Management in sesame” was carried out at the Agronomy Research Farm of School of Agricultural Sciences and Rural Development, Nagaland University, Medziphema campus, during Kharif season of 2017-18. Nine treatment combinations consisting of three level of planting density i.e., T1- (20cm x 10cm), T2 (30cm x 10cm) and T3 (40cm x 10cm) along with three levels of nutrient management practices i.e., N1 (100% RDF), N2 (75% RDF + 25% FYM) and N3 (75% RDF + 25% poultry manure) were tried in factorial randomized block design with three replications. Conclusion: Among the different planting density and nutrient management practices, combined effect of 20cm x 10cm planting density with 75% RDF + 25% FYM nutrient recorded highest growth attributes viz., plant height (cm), number of leaves plant-1, number of branches plant-1 and yield attributes viz., number of capsules plant-1, seed yield (kg ha-1) and stover yield (kg ha-1). However, the highest net return (₹16687.66) and B:C ratio (1.13) was obtained from the treatment combination of 40cm x 10cm planting density along with combination of 75% RDF + 25% poultry manure. Hence, the combined application of manures with inorganic source of nutrients with reduced planting density recorded higher growth and yield attributes thereby resulting higher economic return than the application of RDF alone.

To evaluate the effects of integrated nutrient management on growth and yield of BARI tomato-14 and soil fertility, a pot experiment was conducted in the net house of the department of Agricultural Chemistry of Bangladesh Agricultural University, Mymensingh during the period from October 2011 to April 2012. The experiment was laid out in a completely randomized design with 11 treatments and 3 replications. Treatments were control, RDCF100, 75% RDCF, 50% RDCF, 75% RDCF + PM2 t /ha, 75% RDCF + RS3 t /ha, 75% RDCF + PHRD, 50% RDCF + PM3 t /ha, 50% RDCF + RS5 t /ha, 50% RDCF + PHRD, PM3 t /ha + RS5 t /ha + PHRD. Among the treatments applied in combination of PM2 t /ha+ 75% of RDCF excelled in growth trends of morphological characters like plant height, number of branches plant- 1, number of leaves plant-1; available soil P and S. But sole application of RDCF100 recorded higher values for almost all morphological characters namely number of branches plant-1, number of leaves plant-1, fruit diameter, fruit weight plant-1 and yield of tomato following the same trend as seen in combined application of CF and PM. Among the plant hormone applied in combination, RDCF75% + PHRD showed the highest plant height. The more number of leaves plant-1, number of branches plant-1, yield and yield parameters as compared to other treatments were also significantly influenced by application of PH. Combined application of 50% of RDCF+RS5 t /ha increased exchangeable soil K. PM3 t /ha+ RS5 t /ha+ PHRD conserved more organic carbon and total soil N. Results showed that the integrated use of PM, RS along with CF increased the availability of nutrients throughout the growth period by maintaining the long term productivity for sustainable production of tomato.
