Effects of different supplemental levels of whey protein on the properties and structure of millet–wheat mixed flour dough
In this study, the effects of whey protein on the macro- and microstructural quality of millet noodles and the underlying action rule were evaluated. The effects of different proportions of whey protein (2%, 4%, 6%, 8%, and 10%) on the farinograph properties, stretching properties, cooking quality, textural properties, and sensory quality of millet noodles were analyzed and compared using a farinograph and a texture meter and via Fourier transform infrared spectroscopy and scanning electron microscopy. Moreover, the effects of whey protein supplementation on the sulfhydryl content, gluten formation, and microstructure of millet noodles were investigated. Results showed that the addition of whey protein improved the farinograph properties of the dough, reduced dough hardness, and increased the maximum tensile force of the noodles. The addition of whey protein increased the content of free sulfhydryl and glutenin macropolymer of millet noodles, changed the secondary structure of protein in the original noodles, and promoted the formation of a uniform and continuous microstructure of noodles. Therefore, the addition of whey protein can improve the quality of noodles to some extent.
Growth of Maize and Residual Nutrients in Soil Treated with Palm Kernel Shell Biochar
Biochar is a sustainable approach to greening the environment with its unique ability to improve soil fertility, increase crop yields, carbon sequestration, and retain soil moisture. Although multiple studies have reported on the benefits of biochar as an amendment on agricultural lands, less is known about its effects of palm kernel shell biochar (PKSB) on tropical soil in Malaysia under field condition. Therefore, a 3-month field experiment was conducted to investigate the effects palm kernel shell (PKSB) biochars with reduced rate of NPK fertilizer on maize growth, soil fertility and nutrients uptake. 20 t ha-1 of biochar was added to a maize field with four treatments (control, NPK Fertilizer (F), PKSB and FPKSB) and four replications were arranged in randomized block design (RBD). Biochar amendment has increased the biomass by 1.01 t ha-1 for FPKSB as compared to treatments with F only. Available P was the highest in combined treatment plot as the acidity of soil is lowered which resulted in improved cation exchange capacity (CEC) and elevated the bioavailability of P by 40 %. Biochar application has also increased macronutrient uptake compared to F only i.e. P uptake and K uptake increased significantly 41.94 kg/ha and 31.4 kg/ha for FPKSB, respectively compared to individual F application. Principal Component Analysis (PCA) confirmed that P and K uptake were closely related to the biomass yield, whereas soil CEC could be influenced by the soil pH and available P.
Microwave-assisted dehulling of pigeon pea (Cajanus Cajan)
This research was undertaken to examine the impact of microwave pre- treatment on pigeon pea dehulling. The experiments were conducted three microwave power levels, 450 W, 630 W, and 810 W, at different five exposers from 60 to 180 s at the time interval of 30 s to see pigeon pea dehulling with the pre-milling treatment of microwave exposure for achieving maximum dehulling yield, dhal yield, good dehulled grains in terms of quality with minimum dehulling loss. It has been noted that dehulling yield increased with microwave power and exposure period. The highest dehulling yield, 73.46%, was achieved 810 W with 150 s exposure. At these conditions, max dhal yields, i.e., 72.30%, with dehulling loss of 6.46%. So, this requirement was the correct one to be the better one to get a higher dhal yield. These findings are also valuable for the pulse processing industry and fabricators for designing a continuous type pulse pre-milling treater unit. Thus, it could be highlighted that the microwave pre-milling treatment is more suitable for pulse processing like pigeon pea. This also presents an improvised method for pre-milling treatments for commercial adoption.
Yield Potential and Economic Feasibility of Wheat Varieties under Integrated Nutrient Management in Semi-Arid Region of India
A field experiment was conducted during two consecutive winter (rabi) seasons of 2016-17 and 2017-18 at Sardar krushinagar Dantiwada Agricultural University, Sardar krushinagar, Gujarat, India to assess the impact of varieties and integrated nutrient management practices on yield and economics of wheat. The treatments consisted of four wheat varieties viz. GW 273, GW 322, GW 451 and GW 496 and six integrated nutrient management practices viz. control, 100% RDF, 100% RDF + Azotobacter + PSB, 75% RDF + Azotobacter + PSB, 75% RDF + Azotobacter + PSB + ZnSO4 and 50% RDF + 25% N through FYM + Azotobacter + PSB + ZnSO4. Results indicated that maximum values of growth and yield parameters were recorded in variety GW 451 which was at par with GW 496. This variety proved as best in realizing the highest grain yield (4.99 t ha-1), net returns (₹ 68173 ha1 and benefit cost ratio (2.0). Among nutrient management practices, application of100% RDF (120 kg N and 60 kg P2O5 per ha) + Azotobacter + PSB significantly improved growth and yield attributes and produced 37.1 and 24.8% higher grain and straw yields over control, respectively. The highest economic returns and B:C ratio were also computed in this treatment. Therefore, wheat variety GW 451 fertilized with 100% RDF + Azotobacter + PSB can be suggested for higher grain and straw productivity and profitability.
Development of a control strategy for aeration systems of stored grains
A new grain aeration control strategy has been developed. This strategy is based on a simulation of the aeration process and acquisition data in real- time. This strategy was implemented using a simulation model coupled with intrinsic and extrinsic silo acquisitions. The decisions to activate and deactivate the aeration process depend on four conditions on the state of grain layers in real-time and simulation of the aeration process. This strategy has shown its significant safe storage potential. Indeed, for three test periods (P1, P2, and P3). The period P1 makes it possible to have an average temperature of stock of 15 0C in response to the said strategy in the critical summer period (P2), it has been noted that it does not have considerable cooling power. However, we have noticed the homogeneity of temperature distributions in grains. Additionally, for period P3 the average temperature reached there in the silo is around 25 0C during August (the period P3) which is considered beneficial for the new harvest.
