Field experiment was conducted to evaluate the influence of application of nitrogenphosphorus fertilizer and harvesting time on growth, yield, oil content and physiochemical properties of M. spicata L. oil. Eight treatment consists of different N-P fertilizer dose and four harvesting period were used for the study. Maximum plant height was found at N2P2 treatment. N2P3 fertilizer treatment produced highest herb yield. The oil content of M. spicata L. was maximum at 130 day harvesting period. The oil refractive index was also enhanced with increasing harvesting time. In case of interaction effect between different level of nitrogen-phosphorus and harvesting time showed highest oil concentration at N2P2 treatment within 130 days harvesting time. Where as the optical rotation, acid value and density of oil was remain more or less same during the whole experiment period.

An experiment was conducted in field condition to study the effect of nitrogen-phosphorus fertilization on growth, yield and nutrient content of cabbage. The experiment was laid out in randomize block design with three replications. The yield and yield components were maximized by N3P2 fertilizer treatment. Nutrient content of cabbage varied with fertilizer treatment. The maximum amount of reducing sugar, ascorbic acid, phosphorus were found at the highest rate of N - P fertilization whereas accumulation of titrable acidity, iron, calcium were maximum at the rate of N2P2 treatment. However pH, ash content were more or less same throughout the experiment. Bangladesh J. Sci. Ind. Res. 41(1-2), 41-46, 2006

A field experiment was conducted to evaluate the effects of pre-sowing treatment of calcium chloride and phosphorus fertilization individually and combinely on the yield, oil content and physico-chemical properties of groundnut. This experiment consists of three pre-sowing treatments of calcium chloride solution (0%, 0.15%, 0.25%,0.50%) and four doses of phosphorus (0,30,45,60,75 kg/ha) with control. Pod yield of groundnut found 2.25 t/ha was maximum at 0.50% calcium chloride presowing treatment. The number of pods/plant (26.86) as well as, weight of 100 seeds (88.49) found significantly increased by applying 75 kg P2O5 / hectare when compared to the control. From the interaction of pre-sowing and fertilizer treatments, ie, 0.50% pre-sowing of calcium chloride (T3 ) with 75 kg P2O5 / hectare ( P4) produced significantly increased of pod yield (2.54 t / ha) and oil content (47.25%) of groundnut. Responses of pre-sowing and fertilization treatments on physico-chemical properties of groundnut oil such as refractive index, peroxide value, density remained unchanged throughout this experiment.

Citronella Grass

Currently, the cultivation of citronella grass (Cymbopogon nardus L.) is widely developed in highland areas dominated by Andosol soil. Andosol possesses low phosphorous availability, strongly bound to Al and Fe. This research was aimed to examine the effect of P fertilizer on C. nardus L. at Andosol. The research was conducted from June 2014 to August 2015. Phosphate fertilization stimulated plant growth, yield and oil quality of citronella grass on Andosol. The most suitable Phosphorus dosage at 1.08 g plant-1 (10.8 kg ha-1) produced high total fresh herb yield and oil quality of citronella grass. Total fresh herb yield increased 21.2% (3.4 kg plant-1 year-1) compared to control. Whereas citronella content, oil content and oil yield were 35.2%, 1.64% and 1.27 % respectively. The phosphate residue in Andosol can be potentially utilized for the next planting season.

A field experiment was conducted at Instructional-cum-Research (ICR) Farm, Assam Agricultural University, Jorhat during Rabi seasons of 2016-17 and 2017-18 to study the response of niger to different levels of nitrogen, phosphorus and potassium as well as sulphur on growth, yield and oil content of niger. The experiment was laid out in Factorial Randomized Block Design with three replications. The treatments comprised of three NPK levels viz., F1 (20-10-10 kg N-P2O5-K2O ha-1), F2 (25-12.5- 12.5 kg N-P2O5-K2O ha-1), F3 (30-15-15 kg N-P2O5-K2O ha-1) and three S levels viz., S1 (no sulphur), S2 (10 kg S ha-1), S3 (20 kg S ha-1). Application of F3 (30-15-15 kg N-P2O5-K2O ha-1) and S3 (20 kg S ha-1) recorded maximum and significantly higher seed yield (q ha-1), oil content (%), oil yield (q ha-1) as well as growth and yield attributing parameters viz., plant height, number of leaves plant-1, number of branches plant-1, number of capitulum plant-1 and number of seeds capitulum-1 during both the years. Test weight was not influenced significantly during both the years. Interaction effects of NPK (F) and sulphur (S) were found to be not significant in respect of growth and yield attributing characters in both the years. In case of seed yield (q ha-1) and oil yield (q ha-1) interaction effect were found to be significant in both the years.The highest gross return (Rs. 23,905.00 in 2016-17 and Rs. 22,400.00 in 2017-18) and net return (Rs. 11,184.86 in 2016-17 and Rs. 9679.86 in 2017-18) were recorded by F3S3 in both the years. In case of benefit-cost ratio, the higher value (1.88 and 1.76, respectively) was recorded with F3S3 during 2016-17 and 2017-18.

Modified alkyd resins with different amounts of vegetable oil contents (sunflower oil) and different catalysts are synthesized with the incorporation of post-consumer polyethylene terephthalate (PET) as a partial substitute for phthalic anhydride. It is found that the properties of the products obtained are directly related to the oil content. The polymerization reactions are followed by the acid value. The modified binder contains 50% oil and 10% PET in the presence of LiOH as the catalyst by using microwave irradiation. The AV value is attained in a short amount of time; it is found that the glass Transition Temperature (Tg) of the modified binder is -1.7 °C. The stiffness and roughness of the printed fabrics by using the modified binder are better than those of the commercial binder for both cotton and cotton/polyester fabrics. Moreover, it is clear that the overall fastness properties of the fabrics printed by using the modified binder in the formulation of printing pastes are higher or comparable to those that use commercial binders.

The physiocochemical properties of Jatropha curcas kernel oils were characterized as potential biodiesel, including oil yield per plant, seed oil content, kernel oil content, acid value, iodine value, saponification value and cetane number. Twenty-five accessions of Jatropha curcas were used for oil content measurement sranging from 21.14 to 40.66 %with a mean value of 32.85% and Kernels oil 48.59 to 60.45 % with a mean value of 56.28 %. The seed index ranged significantly from a seed weight of 45.45 to 64.45 g. Oil yields per plant ranged from 0.44 to 2.85 kg with a mean value of 1.70 kg per plant, respectively. To understand the properties of acid value, iodine value, saponification and cetane number, experimental physio-chemical studies were performed. Since these properties are critical for determining the current oil condition. The current study confirms that accession seeds performed higher than international saponification value, iodine value and cetane number standards may be an important source for meeting potential energy requirements.
