<p><strong>Indonesian</strong><br />Beras berfungsi sebagai makanan pokok dan bahan baku berbagai produk pangan lainnya yang memerlukan kualitas tertentu. Perbaikan kualitas beras tidak memberikan insentif bagi petani dan pedagang di Indonesia, khususnya melalui perontokan, pengeringan, dan penggilingan. Di pihak lain, sebagian besra negara-negara penghasil padi member perhatian lebih pada peningkatan kualitas beras. Kualitas beras meliputi sifat-sifat fisik yang mempengaruhi penampilan maupun sifat-sifat kimia yang menentukan kualitas jika dimasak. Proses produksi, pasca panen, penggilingan dan pemasaran mempengaruhi kualitas beras. Peningkatan kualitas beras akan menguntungkan produsen maupun konsumen beras. Agar pedagang beras bersedia melakukan pasca panen secara baik diperlukan insentif harga yang memadai untuk gabah kering giling dan beras, misalnya harga pembelian oleh pemerintah. Teknologi pasca panen juga harus diperbaiki agar kualitas beras yang dihasilkan menjadi lebih baik.</p><p> </p><p><strong>English</strong><br />Aside from being a staple food, rice also has many uses, especially for food industry. Various rice uses require quality evaluation according to the requirement for a specific end use. Whether rice is acceptable for an intended use is determined by quality testing based on a fixed set of criteria. In Indonesia, the main problem of rice quality improvement is the absence of incentive for farmers and traders to improve rice quality, especially through proper threshing, drying, and milling. On the other hands, most rice producing countries are currently paying more attention to the development of post harvest handling and processing to ensure higher rice grain quality. Rice quality is multidimensional. It includes both physical characteristics that influence appearance, and chemical characteristics that determine cooking quality. Thus, rice grain quality is determined by: production process, post harvest handling, milling and marketing techniques. Among rice post harvest handling, proper threshing, drying, milling, and storage are the key points to produce good quality rice. Rice quality improvement is expected to increase national welfare by raising the value of rice to either consumers or producers. In order to encourage rice businessmen to do the proper post harvest handling, there should be attractive price incentives policy for selling dried paddy (GKG) and milled rice (beras). Price incentive could be in the form of government purchasing price (HPP). In other words, there should be an attractive incentive to do a proper threshing, drying and rice milling by using improved technology in order to produce high quality rice.</p>

There is much doubt as to whether, in fact, the combination of nitrogen and silicate fertilization can increase yield and post-harvest yield in rainfed rice. The objective of this study was to investigate the effect of silicate and nitrogen fertilization on the development, quality, yield and post-harvest yield of rice cultivated in the rainfed environment. A field experiment was carried out in the 2014/2015 harvest in a 4 &times; 4 randomized block design with four replications. The first factor corresponded to the nitrogen doses (0; 50; 100 and 200 kg ha-1 of N), in the form of urea, and the second factor at silicon doses (0; 7.5; 15 and 30 kg ha-1 Si), in the form of calcium silicate. Si affected the chlorophyll content at 45 days after sowing (DAS) suggesting being important in floral differentiation. The increase in N doses caused higher levels of chlorophyll in rice leaves at 55, 65 and 85 DAS, regardless of whether they supplied Si. Plant height, number of tillers, weight of one thousand seeds, total grain yield and of whole grains were not influenced by the Si supply. However, Si doses reduced the yield of broken grains, thus reducing postharvest losses and, consequently, improving grain quality in the beneficiation process.

The Impact

The purpose of the research is to identify effi cient microfertilizers and growth stimulants considering biologi- cal features of new corn hybrids of different FAO groups under irrigation conditions in the South of Ukraine and trace their impact on grain productivity of the plants. The methods of the research are the fi eld method – to study the interaction of the research object with experimental factors of the natural environment, to register the yield and evaluate the biometrical indices; the laboratory method – to measure soil moisture, grain moisture content and grain quality indices; the statistical method – to evaluate the reliability of the obtained results; the calculation methods – for economic and energetic assessment of the growing techniques used. The results of the research. The paper defi nes the impact of microfertilizers and growth stimulants on the yield and grain quality of the corn hybrids of different maturity groups and on the economic effi ciency of growing them. The conclusions of the research. Under irrigation conditions of the Southern Steppe of Ukraine it is recommended that the following hybrids should be grown in dark-chestnut soils: early maturity DN Pyvykha, medium-early Skadovskyi, medium maturity Kakhovskyi and medium-late Arabat, using the growth stimulants – treating the seeds with Sezam-Nano and fertilizing with Grainactive at the stage of 7–8 leaves.
