W latach 1992-1997 przeprowadzono w ramach doświadczalnictwa terenowego ODR Szepietowo, 36 doświadczeń polowych ze wszystkimi gatunkami zbóż. W doświadczeniach porównywano plonowanie odmian w warunkach gospodarstw ekologicznych (bez nawożenia mineralnego i chemicznej ochrony roślin). Na podstawie otrzymanych wyników można stwierdzić, że zboża jare plonują zdecydowanie lepiej i wierniej niż zboża ozime. Wśród zbóż jarych najwyższy plon wydały odmiany: pszenica - Broma, jęczmień - Klimek, owies - Boryna i Farys, pszenżyto jare - Gabo. Spośród zbóż ozimych najlepiej plonowały: żyto - Motto, Warko i Amilo, pszenica - Lama, pszenżyto - Presto.

Within the field experimentation of Agricultural Advisory Centre in Szepietowo 36 field experiments (with different cereal species) were conducted in 1992-1997 years. In these experiments yielding of different varieties in ecological farms (without mineral fertilisation and chemical plant protection) was compared. It was observed that spring cereals yielded better than winter cereals. The following varieties of spring cereals gave the biggest yields: wheat - Alkora i Henika, barley - Klimek, oat - Boryna and Farys and triticale - Gabo. Whereas rye-Motto, Warko and Amilo, wheat - Lama and triticale - Presto gave the biggest yields among winter cereals.

The objective of this study was to analyze the content of heavy metals and arsenic in soil and cereal grains as well as to evaluate the possible human risk in the central region of Peru. The soil samples of corn and barley grains were collected from seven agricultural zones and the concentrations of Cu, Fe, Pb, Zn and As were determined with the method of atomic absorption flame spectrophotometry. PERMANOVA showed that the effect of the type of crop and the sampling zone significantly influence the concentrations of heavy metals and As in soil and corn and barley grains (p < 0.05). PCA for heavy metals and As in soil and grain samples of the cereals studied showed that the first two main components represented 81.03% and 94.77% of the total variance, respectively. Hazard Quotient (HQ) for ingestion was the most significant. The HQ values of Pb and As in crop soils indicated that detrimental health effects are unlikely (HQ < 1). The soil hazard index (HI) values of both crops did not exceed the threshold value of 1 (HI < 1). The carcinogenic risk level (CR) of As from ingestion of corn and barley crop soils contaminated by As was higher in children than in farmers and adults. The bioconcentration factor (BCF) of As was higher in barley grains than in corn grains. The THQ of As exceeded the target value of 1 in 100% of the barley and corn sampling sites. The RC of As in grains exceeded the acceptable risk level of 10–6 in all sampling zones.

Great advances have been made in recent years in marker detection systems and in the techniques used to identify markers linked to useful traits. While RFLP markers have been the basis for most work in crop plants, useful markers have been generated using RAPD and AFLP methods. More recently, microsatellite or simple sequence repeat (SSR) markers have been developed for major crop plants and this marker system is predicted to lead to even more rapid advances in both marker development and implementation in breeding programs. Identification of markers linked to useful traits has been based on complete linkage maps and bulked segregant analysis. However, alternative methods, such as the construction of partial maps and combination of pedigree and marker information, have also proved useful in identifying marker/trait associations. The value of markers in analysing the inheritance of traits in crop plants and understanding genome structure and organization is now well established. The different properties of markers systems and their applications in genome analysis and molecular breeding of cereals species are discussed.

This study was aimed at investigating profitability of selected coarse cereals production in major producing states of India through analyzing cost, return and profitability of coarse cereals cultivation. Cost concepts and farm business income measures used for analysis the data ranging from 1980-81 to 2011-12. Net return of coarse cereals cultivation was observed to be highest for maize and it was highest in Bihar (Rs. 15,429/ha) and lowest Uttar Pradesh (Rs. -4,006/ha). Net return from cultivation of sorghum was found to be highest in Andhra Pradesh (Rs. 952/ha) and lowest for Madhya Pradesh (Rs. -1,456/ha). For pearl millet net return was highest in Andhra Pradesh (Rs. 4,995/ha) and lowest for Karnataka (Rs. -1,252/ha) whereas cultivation of finger millet was observed to be at a loss.

Improving Nitrogen Use Efficiency (NUE) in crops of winter wheat is of interest in Poland, due to their significant share in the sown area. The aim of this study was, therefore, to determine the relationships between grain (Yd) and N yields (Yn), NUE, Water Use Efficiency (WUE) depending on N rates (F) and actual potential evapotranspiration (APET). The study used the results of field experiments, conducted in the years 2003–2013 in two locations in Poland. In the experiments, wheat was fertilized with doses of 40, 80, 120, 160 and 200 kg N/ha under the fertilization with P, K, Mg and Ca. It was found that the dose range of 80 ± 40 kg N/ha allowed to obtain Yd of 5.34 ± 1.43 t/ha and NUE values of 116 ± 17%, which brought the risk of soil N mining. Increasing N doses (160 ± 40 kg/ha) increased Yd (6.08 ± 0.71 t/ha) and allowed for obtaining the desired values of NUE (73 ± 5%), Yn (119 ± 18 kg/ha) and N surplus (43 ± 13 kg/ha). The performed statistical analysis showed that Yd, Yn and WUE had grown with increasing doses of N under the influence of water shortages in the range of APET less than 398 mm. Under these conditions positive interaction between Yd, Yn, WUE depending on F and APET has been demonstrated. Only for a dose of 200 kg N/ha were found negative interactions between Yd, WUE on F and APET. NUE decreased with increasing N doses. The relationship between NUE and WUE was positive but specific for N doses due to the statistically significant interaction of F×WUE. The maximum value of WUE obtained in the experiments was 26 kg grain/ha/mm. In the absence of limiting factors WUE increased linearly together with growing NUE up to the value of 93.9% and then linearly decreased. In the range of the desired NUE values (50–90%), WUE values were between 16,4–23,5 kg grain/ha/mm.

The aim of the studies was to evaluate the herbicidal contaminations in soil. Monitoring tests were carried out in two periods: 2002–2008 and 2010–2013, on cereal plantations located in south-western Poland. The samples of soil were collected at harvest time. The determination of 2,4-D, MCPA, diflufenican, dicamba, chlortoluron, fluroxypyr, isoproturon, clopyralid residues were conducted using the chromatography GC/ECD and HPLC/UV. Comparing the research results from both periods, a decrease of several percent in the number of the samples with residues was observed. In the years 2010–2013, the average residues of herbicide determined in 27% of samples ranged from 0.0012 to 0.0052 mg kg⁻¹ .1
