The main nutrients in rice are starch, protein and lipids, and their contents and physicochemical properties have important effects on rice qualities. The aging process of rice is very complex, which not only changes physical and chemical properties, but also changes its physiological characteristics in rice grain. In this paper, the changes of physicochemical properties of its main nutrients (starch, protein and lipids) during storage were reviewed. At the same time, the effects of rice aging on its quality characters and the mechanism of rice aging were also discussed, which could provide reference for solving the problem of rice quality decline during storage.

The paper presents the results of evaluating the rice variety Rapan grown in 2018, 2019 at different seeding rates and doses of nitrogen fertilizers, according to the main amylographic characteristics of starch dispersion and fracturing. In 2018 and 2019, when growing variety Rapan with seeding rates of 4, 6 and 8 million viable seeds, the highest values were noted for the “fracturing” trait at a nitrogen dose of 92 kg/ha of active ingredient. In 2018, they amounted to 31, 35 and 41%, respectively, in 2019 - 13, 12 and 12%, respectively. The following tendency in the change of rice quality traits was noted: in the samples grown without the use of nitrogen, low fracturing was revealed, while in the N92 variants the value of the trait was maximum, with N184 - the minimum. Indicators for the “maximum viscosity” at a nitrogen dose of 92 kg / ha of active ingredient had the lowest values at all three seeding rates and amounted to 484, 500 and 485 Br.units in 2018, respectively. In 2019 - 471, 440 and 480 Br. units. The opposite pattern was observed when determining the viscosity indices: at the minimum values of fracturing, the viscosity indices were maximum and decreased at high values of this trait.

In connection with the spectrophotometric study of population-type characteristics of various kinds of stars, a statistical analysis of kinematical and distribution parameters of the same stars is performed at the Toruń Observatory. This has a twofold purpose: first, to provide a practical guide in selecting stars for observing programmes, second, to contribute to the understanding of relations existing between the physical and chemical properties of stars and their kinematics and distribution in the Galaxy.

Organic farming is one of the management strategies that improve productivity of marginal uplands. The study aimed to: (1) evaluate effects of various organic-based fertilizers on the growth and yield of corn; (2) determine the appropriate combination for optimum yield; and (3) assess changes on the soil physical and chemical properties. Experiment was laid out in Randomized Complete Block Design, with 3 replications and 7 treatments, namely; T0=(0-0-0); T1=1t ha-1 Evans + 45-30-30kg N, P2O5, K2O ha-1; T2=t ha-1 Wellgrow + 45-30-30kg N, P2O5, K2O ha-1; T3=15t ha-1 chicken dung; T4=10t ha-1 chicken dung + 45-30-30kg N, P2O5, K2O ha-1; T5=15t ha-1 Vermicast; and T6=10t ha-1 Vermicast + 45-30-30kg N, P2O5, K2O ha-1. Application of organic-based fertilizers with or without inorganic fertilizers promoted growth of corn than the control. But due to high infestation of corn silk beetle(Monolepta bifasciata Horns), its grain yield was greatly affected. In the second cropping, except for Evans, any of these fertilizers applied alone or combined with 45-30-30kg N, P2O5, K2O ha-1 appeared appropriate in increasing corn earyield. Soil physical and chemical properties changed with addition of organic fertilizers. While bulk density decreased irrespective of treatments, pH, total N, available P and exchangeable K generally increased more with chicken dung application.
