Presowing Treatment

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.

Onion seeds have one of the lowest longevity among the cultivated crops as it loses viability within a year. The unmarketable seeds have no reported food value or feed value. Onion seeds contain considerable oil content which has potential industrial utility. The present study reports the changes in the quality of seed oil extracted from seeds stored for one year (2019-2020), after which the seeds were unmarketable due to low germination. The physico-chemical properties of seed oil were studied in four onion (Allium cepa L.) varieties (Bhima Safed, Bhima Super, Bhima Dark Red and Bhima Shakti) by standard analytical test. The per cent oil content varied from 12.94% - 16.02% and storage resulted in 0.64% loss in seed oil content. The mean seed germination in freshly harvested seeds was 80.50%, which declined to 52.33% after one year of ambient storage. The electrical conductivity, which measures the membrane integrity increased by 108.60% in one-year-old seeds. The physico-chemical properties of the seed oil deteriorated with the age of the seed. In comparison to the control, the acid values and peroxide values of the seed oil increased by 51.11% and 12.90% respectively, while saponification value decreased by 36.18%. Among the varieties, Bhima Dark Red had the highest degradation in the seed storability and vigour, which also had the highest deterioration in the lipid quality. The present study reports for the first time the degradation of seed lipids during ageing in onion which might be contributing to the poor storability of onion seeds.

Background: Phosphorus is the crucial element to enhance yields as well bio-chemical properties namely protein and oil content in groundnut. Buildup of insoluble phosphates and chemical fixation in soil reduces phosphorus consumption ability in plants. Phosphorus use efficiency (PUE) can be increased with higher levels of phosphorus rate. The study was framed to investigate the effect of phosphorus fertilization on yield, nutrient acquisition, use efficiency and bio-chemical compositions of groundnut. Methods: The experiment was conducted in summer seasons of 2016 and 2017, using split plot design with three varieties (‘JL-24’, ‘Gangapuri’, ‘TAG-24’) in main plot and four fertilization levels (0, 40, 60, 80kg P2O5 ha-1) in sub plots. Result: The study revealed that pod yield enhanced significantly by 15.4%, 27.3% and 39.9% with increase in fertilization rates from 40kg to 80kg ha-1 compare to unfertilized plots. Protein and oil content showed a positive response with phosphorus application. Agronomic efficiency, recovery efficiency and utilization efficiency were also increased with phosphorus rates, whereas, partial factor productivity, agro-physiological efficiency and physiological efficiency had decreasing trends. ‘Gangapuri’ gave higher pod yield (1.80t ha-1), protein (24.27%) and oil (45.41%) content than other selected varieties. Enhanced phosphorus rate also increases nutrient uptake in groundnut.

Experimental study on the physico-chemical properties of bio-oil and diesel emulsification has been carried out in this paper, which was based on the preliminary experiment. The effect of surface tension and viscosity on the stability of emulsions were particular concerned. It was found that the longest stable time, the lowest viscosity and lowest surface tension can be obtained simultaneously when the hydrophile and lipophile balance (HLB) value was of the optimal value, i.e. 6.5. Experimental results indicated that the stable time of emulsion decreased rapidly with the increase of bio-oil content, while the value of surface tension and viscosity increased. Meantime, it was shown that the most stable emulsions had the lowest value of viscosity and surface tension.

The physico-chemical properties of four popular groundnut (peanut) varieties namely Trombay-Akola Groundnut-24 (TAG-24), Kadiri-6 (K6), Kadiri-9 (K9), and Kadiri-Harithandra (KH) were determined by following the standard measurement methods. The average geometrical mean diameter (GMD) and sphericity values of peanut pods ranged from 14.91 mm (K9) to 16.61 mm (KH) and from 0.56 to 0.63, respectively. The 100 whole pods mass for four different peanut varieties are significantly different from each other. The bulk density of peanut pods ranged from 232.7 kg/m3 (K9) to 289.0 kg/m3 (K6) and these are significantly different from each other. The calculated porosity values for peanut pods varied from 37.89% (KH) to 47.32% (TAG-24). For the kernels, the highest GMD value of 10.57 mm was recorded for the KH variety and the lowest GMD value of 9.33 mm was found for the K6 variety. Sphericity values for peanut kernels ranged from 0.71 (K6) to 0.78 (K9). The average 100 kernels mass ranged from 46.23 g (TAG-24) to 56.34 g (for K9). The bulk density of kernels ranged from 583.4 kg/m3 (K9) to 611.9 kg/m3 (K6). However, the bulk density of peanut kernels is not significantly different for the varieties from each other. The true density values of peanut kernels ranged from1020.4 kg/m3 (K6) to 1052.0 kg/m3 (TAG-24). The porosity values for peanut kernels ranged from 40.06% (K6) to 43.64% (TAG-24) and they are not significantly different for the varieties from each other. Among all the varieties, KH variety had the lowest ash content of 2.18% and also the lowest protein content. The oil content of selected peanut varieties ranged from 45.36% (K9) to 48.22% (KH).The physical properties measured in this study are helpful to design and develop suitable pre and primary processing equipment. Proximate composition gives an idea to decide peanut’s suitability for manufacturing products such as peanut butter.

Castor oil having low content of unsaponifiable matters was chosen for the development of new jute batching emulsion processes. The suitability of the castor oil was also assessed in terms of its favourable colour, odour, specific gravity, acid value, iodine value, saponification value, viscosity, pour points and flash points in comparison to those of conventional JBO. Different recipes for the production of emulsions were standardized in the industrial scale and their suitability were assessed according to their stability, specific gravity, temperature, viscosity and pour points. The recipes were used to spin jute fibre in the jute mill machines. The yarn products were studied to evaluate their work performances based on their physico-chemical properties: moisture regain, t.p.i., W.I., count, strength, tenacity, extension, textile modulus, toughness, QR, oil content and unsaponifiable matters. The yarn products were particularly evaluated in terms of their unsaponifiable matters based on the IJSG criterion. The yarns of processes show quality ratio 93.93 to 104.20 and unsaponifiable matters ranging from 126.05 to 414.92 mg/kg yarn and easily pass the IJSG criterion. The processes therefore appear to be of commercial importance. Key words: Food items, IJSG criterion, JBO, Jute sacks, Unsaponifiables, Vegetable oils.

In Burkina Faso, vegetable production is a very important asset for its socio-economic development. However, this production faces many constraints that negatively affect its potential. The use of organic fertilization appears to be an alternative to address these constraints and could also promote sustainable agricultural production. In such a context, this study was conducted on tomato using two bio-fertilizers based on local substrates (Bokashi compost and compost enriched with Trichoderma harzianum). The objective was to assess the efficiency of the two bio-fertilizers by determining their effects on tomato yield and soil physico-chemical properties. It was conducted from 2018 to 2020 in Soala using a randomized Fischer block design with six treatments in three replications. The treatments were T0 (control), T1 (NPK+urea), T2 (Bokashi compost), T3 (compost enriched with Trichoderma harzianum), T4 (T1+T2) and T5 (T1+T3). The results showed that the bio-fertilizers alone contributed to maintain the neutrality of soil pH and very significantly improved its C, N, P and K content. Moreover, in combination with or not with NPK+urea, they influenced significantly plant growth, yield components and yield of tomato compared to T0 plot. In these years of trials, compost enriched with Trichoderma harzianum in combination with or not with NPK+urea, was found to be the most improving tomato yield and the increase was more than 300%. This compost could be therefore recommended to farmers in agriculture in general and particularly for vegetable production.

The study was conducted to analyze the physico-chemical properties of various levels of brick kiln dust in soil application (0, 5, 10, 15, 20, 25, 30, 40 and 50%), before planting and after harvesting of potato (Solanum tuberosum) crop and to observe their impact on various parameters of potato plant. The pH, EC, CEC, WHC, pore space, sulphate, chloride, phosphorus, magnesium, zinc, manganese and boron increased at all the levels of brick kiln dust, while, nitrogen and potassium decreased at all the levels before planting of potato crop. After harvesting of potato crop all physico-chemical properties were still greater than control but less than pre-planting of potato, except P and Mg which decreased gradually upto 30%; and K as well as Mn upto 40%, and then they increased in subsequent levels. While N was recorded only in control and at 50% treatment. Application of brick kiln dust in soil from 5% to 40% was found beneficial for plant growth, yield, biomass, photosynthetic pigments, carbohydrate contents, and phosphorus and potassium concentrations of plants and the highest increase in above parameters was recorded at 25% level. At 50% level, there was marked reduction in all these parameters. However, nitrogen concentration of plants and protein content in tubers decreased gradually as levels of kiln dust were increased.DOI: http://dx.doi.org/10.3126/eco.v18i0.9394Ecoprint: An International Journal of EcologyVol. 18, 2011 Page: Uploaded date: 12/20/2013
