Water extraction variability in the banana root zone affects the reliability of water balance Scientia Agricola
Silva,Alisson Jadavi Pereira da; Coelho,Eugênio Ferreira; Coelho Filho,Maurício Antônio.
Spatial and temporal variability of soil water extraction from the root zone affect soil water balance determination. The number of sensors installed in the root zone in studies addressing water balance is still set arbitrarily. This study provided an investigation of the water extraction process by banana (Musa spp.) roots by (i) determining the variability of water extraction from the banana tree root zone, (ii) detecting differences in the estimation of evapotranspiration (ET) by the soil water balance method when the number of soil profiles monitored in the roots zone varies, (iii) and; determining the minimum number of Time Domain Reflectometry (TDR) probes needed to obtain ET precision and accuracy similar to that determined by a drainage lysimeter....

การศึกษาความสัมพันธ์ระหว่างลักษณะปรากฏ สมบัติเชิงเคมี-กายภาพและสมบัติการหุงต้มของเมล็ดข้าวโดยการวิเคราะห์ภาพ Thai Agricultural
Maturada Jinoros; Somkiat Prachayawarakorn; Somchai Soponronnarit.
After harvesting paddy needs to pass through several processing steps before edible grain kernels are obtained. These processes inevitably affect the kernel quality, both in terms of the physical physicochemical and cooking properties. A number of techniques have thus been proposed to evaluate the various quality attributes of rice kernels. Image analysis is one of the promising techniques for analysis of rice kernel appearances with fast and accurate results. Image-analysis results may also be related to the physicochemical and cooking properties of the kernels. This research explored possible relationships between appearances obtained via image analysis and selected physicochemical and cooking properties of rice kernels. In addition to the basic apparent...

Estimating moisture absorption kinetics of beans during soaking using mathematical models CIGR Journal
Shafaei, Seyed Mojtaba; Masoumi, Amin Allah.
In this paper, fourteen standard models were used to estimate the moisture ratio of three varieties of bean in Iran (Talash, Sadri and Mahali Khomein).  The experiments were carried out using distilled water at three temperatures (5°C, 25°C and 45°C) and three replicates.  The standard models of water absorption were fitted to the experimental data.  To evaluate the models, three parameters: coefficient of determination (R2), chi-square (2) and root mean square error (RMSE) were used.  The appropriate model was chosen based on maximum value of coefficient of determination and minimum value of chi-square and root mean square error.  The effective moisture diffusivity coefficient of three verities in each temperature was estimated by Fick’s equation.  The...

Cooking Qualities of Parboiled Little Millet and Proso Millet: Effect of Soaking and Steaming CIGR Journal
Rangaraju, Visvanathan; Balkrishna, Patil Sagar.
Parboiling of little millet (Panicum sumatrense) and proso millet (Panicum miliaceum) was carried out by soaking at different soaking temperatures (30, 40, 50, 60 and 70°C) and durations of steaming (10, 15, 20, 25 and 30 min). The parboiled millet grains were shade dried and pearled in a laboratory scale pearler cum polisher. Parboiling of these millets was assessed for the cooking qualities, in terms of cooking time, water uptake, swelling index and elongation ratio.  Parboiled little millet took 9 - 14 min for cooking with water uptake ratio of 3.3 - 4.7 and showed swelling index and elongation ratio ranging from 1.73 - 2.74 and 1.69 - 2.61, respectively. For proso millet cooking time and water uptake were recorded as 11 - 13 min and 2 - 4.2, with...

Differential water uptake kinetics in axes and cotyledons during seed germination of Vigna radiata under chilling temperature and cycloheximide treatment Braz. J. Plant Physiol.
Chakraborty,R.; Kar,R.K..
Water uptake kinetics of axes and cotyledons of Vigna radiata seeds has been studied during incubation at chilling temperature (4°C) and under cycloheximide treatment. Germination rate of scarified seeds was faster than intact seeds, which can be correlated with their comparative water uptake kinetics. Chilling temperature during incubation significantly slowed down water uptake by both intact and scarified seeds. Treatment with cycloheximide was also somewhat effective in retarding water uptake, but only in scarified seeds. Water uptake by axes isolated from intact seeds (attached or detached from the cotyledons) was inhibited completely by chilling temperature as well as by cycloheximide treatment while these treatments were ineffective in preventing...
