AB  - Crop rotation and tillage systems are the most important agrotechical measures that interaction with the suppression of weeds and affect the size and composition of the weed seed bank and are in direct correlation with their content in the soil. Knowing seed bank, as well as monitoring the dynamics of the appearance of weed species, constitute the basis for planning and implementation of measures for their effective suppression. The paper presents the evaluation of weed infestation of maize grown in monoculture, 2-year crop rotation (maize, wheat) and 3-year crop rotation (maize, soybeans, wheat) on long-term experiment "Crop Rotation" of the Institute of Field and Vegetable Crops in Novi Sad. Soil samples, taken after the harvest of corn from a depth of 0–15 cm, 15–30 cm and 30–40 cm, were used for the analysis of weed seed bank. By applying the methods of physical extraction, soil samples were irrigated through a system of sieves of different sizes, and by using binoculars and a guide for the determination, a separate determination of seeds was made. The data obtained made it possible to view the number of seeds present in the soil, as well as the vertical distribution of weed species in both arable and subsoil layer.

AB  - The topic of N wheat nutrition was prevalent during the last decades of the 20th century for many reasons such as energy crises, profitability of small grain production, and ecosystem protection and preservation. The objective of this study was to determine the interrelationships between wheat (Triticum aestivum L.) grain N content and other indicators of N nutrition efficiency to better understand the N nutrition process in wheat plants. The experiment included 30 wheat cultivars and experimental lines from Serbia. Plant samples of each genotype were taken at anthesis and maturity. The following parameters related to N accumulation and translocation within the wheat plant were calculated: N content (at anthesis, grain, straw, and total at maturity), N harvest index (NHI), N reutilization (N reU), and N lost (-) or gained (N post-anthesis). Our results showed that N content in the aboveground part of the plant expressed very strong direct positive effects on N yield (phenotypic coefficient 3.78** to 9.34** and genotypic coefficient 1.43** to 2.32**), while its indirect effects varied. The influence of independent variables on grain N content has been changing from year to year in a negative way. Total N accumulation (N total) had the highest negative direct effect in the first year of the study (phenotypic coefficient -2.11**), N total in the second (phenotypic coefficient -2.78**), and N reutilization in the third (phenotypic coefficient -8.49**). Genotypic coefficients indicate that the most frequent strong direct negative effect was N reutilization (-0.47** and -0.99** in the first 2 yr of research, respectively). Nitrogen reutilization and its current assimilation are very important and related to grain N supply processes. Their interaction leads to the conclusion that forming N yield is a very complex mechanism and, as a result, grain yield and quality. The abovementioned parameters could be considered as important criteria in wheat breeding to improve production efficiency and reduce adverse impacts of N fertilizers on the ecosystem.

AB  - The paper examines the effects of lime application at the rate of 3 t/ha on pseudogley soil agrochemical changes and alfalfa yield during a two-year period. The applied lime in combination with mineral fertilizers significantly decreased acidity in H20 (by 0.6 pH units) and in nKCl (by 0.81 pH units). At the same time, there was increase in phosphorus availability (from 6.2 mg/100g of soil, control, to 19.1 mg/100 g of soil, variant with lime) and soil base saturation percentage in the 0-30 cm arable horizon. The performed liming intensified organic matter mineralization, which caused decrease of humus content as well as of mobile Al and Fe content compared to control. Moderate liming improved pseudogley agrochemical properties, which was manifested by increased alfalfa yield. In the first study year 19.7 t/ha of forage and 5.7 t/ of hay, respectively, was produced in control variant, while 28.5 t/ha of forage and 8.2 t/ha of hay, respectively, was produced in a variant with liming. Even higher yield was achieved in the second year of alfalfa utilization (8.5 t/ha of forage and 2.2 t/ha of hay, respectively, was produced in control, and 71 t/ha of forage and 16.3 t/ha of hay, respectively, in a variant with liming). .
AB  - Loše agrofizičke, a naročito agrohemijske osobine pseudoglejnih zemljišta okoline Kraljeva su ograničavajući faktor za gajenje lucerke. Cilj ovih istraživanja je bio da se melirativnom đubrenjem zemljišta-primenom kalcifikacije poprave agrohemijska svojstva pseudogleja i povisi prinos zelene krme i sena lucerke. Rezultati ovih istraživanja pokazuju da se umerenom kalcifikacijom od 3 t/ha kreča može značajno smanjiti kiselost za 0,6 pH jedinica u r^O, i za 0,81 pH jedinicu u nKCl. Smanjenjem kiselosti povećana je pristupačnost fosfora (sa 6,2 mg/100g zemljišta, kontrola, na 19,1 mg/100g zemljišta varijanta sa primenom kreča) i povećan stepen zasićenosti zemljišta bazama u oraničnom horizontu od 0-30cm.

AB  - This paper shows possibilities and ways of cutting potato tubers. In potato seed production, besides standard tuber size (28-55 mm), some part of yield is made of tubers large than 55 mm In ware potato production, when does not exist enough certified seed, or the aim is to gel a high yield of marketable tubers, is possible to use like seed tubers larger than 55 mm in a certain way. There are some questions about economical aspects of exploiting large size tubers for planting, and about relations between yield achieved by planting tuber parts or by planting whole tuber, one and the same size. During two-year study (2001-2002), we tried to find differences in potato crops when we sow whole tubers and when we sow their parts. For the research we choose potato variety Kondor, tuber size 55-65 mm, with evenly spaced 5-6 eye. The cutting was done one month before sowing, in three different ways (in two, three and four parts). That month was the pre-sprouting period. During that period tubers were kept in trays at temperature 16-180C and 85-90% of relative air moisture. The results showed that higher total and marketable yield (tubers heavier than 70 g) was achieved by cutting the tubers in two and three parts, comparing to sowing of whole tubers or cut in four parts.
AB  - U radu su proučavane mogućnosti i načini sečenja krtola krompira U proizvodnji semenskog krompira osim standardne veličine krtola (28-55 mm) dobijaju se i određene količine semenskog krompira frakcije veće od 55 mm. Zbog nedostatka dovoljne količine kvalitetnog deklarisanog semenskog materijala. u proizvodnji konzumnog krompira je moguće koristiti krupne krtole na određen način, naročito ako se ili dobiti što veći udeo krupnih krtola u prinosu. Postavlja se pitanje kako najbolje iskoristili za sadnju ovakve krtole. Posmatrano sa ekonomskog stanovišta nameće se pitanje opravdanosti sadnje krupnih krtola pri najboljim proizvodnim uslovima. Takođe je interesantan i odnos prinosa postignut od sečenih i celih krtola iste semenske frakcije. Dobijeni rezultati sečenih krtola frakcije iste krupnoće-Jakovljević i sar. (1965), pokazuju da je razlika u visini prinosa između pojedinih semenskih frakcija sečenih, znatno veća nego razlika pri sadnju celih krtola iste frakcije, što znači da sečene krtole jače reaguju na veličinu semenskih krtola za sadnje. Iz ovoga proizilazi da se u krupnijih semenskih frakcija pojavljuje manja razlika u korist celih krtola što znači da sečenje krtola ove frakcije može u izvesnim slučajevima biti opravdano. ako je reč samo o visini prinosa, jer je razlika u prinosu neznatna. Tokom 2001. i 2002. godine pokušali smo da utvrdimo da li i u kojoj meri postoje razlike u usevima krompira kada se sade cele krtole i kada se sade njihovi delovi. Za sečenje je odabrana sorta Kondor, frakcije 55-65 mm, koje imaju najmanje 5-6 pravilno raspoređenih okaca na krtoli. Krtole su sečene na tri načina mesec dana pred sadnju (uzdužno, na tri dela i na četiri dela), i do sadnje su ostavljene da formiraju klicu, na temperaturi 16-18°C pri relativnoj vlažnosti 85-90 %. Na osnovu rezultata može se zaključiti da se najbolji efekat u pogledu ukupnog i tržišnog prinosa (krtole veće od 40 mm) ostvaruje korišćenjem sečenja na polovinu i trećinu krtola u odnosu na sadnju celih krtola ili sečenjem na četvrtine.

Zbog nedostatka dovoljne količine kvalitetnog deklarisanog semenskog materijala. u proizvodnji konzumnog krompira je moguće koristiti krupne krtole na određen način, naročito ako se ili dobiti što veći udeo krupnih krtola u prinosu. Postavlja se pitanje kako najbolje iskoristili za sadnju ovakve krtole. Posmatrano sa ekonomskog stanovišta nameće se pitanje opravdanosti sadnje krupnih krtola pri najboljim proizvodnim uslovima. Takođe je interesantan i odnos prinosa postignut od sečenih i celih krtola iste semenske frakcije. Dobijeni rezultati sečenih krtola frakcije iste krupnoće-Jakovljević i sar. (1965), pokazuju da je razlika u visini prinosa između pojedinih semenskih frakcija sečenih, znatno veća nego razlika pri sadnju celih krtola iste frakcije, što znači da sečene krtole jače reaguju na veličinu semenskih krtola za sadnje. Iz ovoga proizilazi da se u krupnijih semenskih frakcija pojavljuje manja razlika u korist celih krtola što znači da sečenje krtola ove frakcije može u izvesnim slučajevima biti opravdano. ako je reč samo o visini prinosa, jer je razlika u prinosu neznatna. Tokom 2001. i 2002. godine pokušali smo da utvrdimo da li i u kojoj meri postoje razlike u usevima krompira kada se sade cele krtole i kada se sade njihovi delovi. Za sečenje je odabrana sorta Kondor, frakcije 55-65 mm, koje imaju najmanje 5-6 pravilno raspoređenih okaca na krtoli. Krtole su sečene na tri načina mesec dana pred sadnju (uzdužno, na tri dela i na četiri dela), i do sadnje su ostavljene da formiraju klicu, na temperaturi 16-18°C pri relativnoj vlažnosti 85-90 %. Na osnovu rezultata može se zaključiti da se najbolji efekat u pogledu ukupnog i tržišnog prinosa (krtole veće od 40 mm) ostvaruje korišćenjem sečenja na polovinu i trećinu krtola u odnosu na sadnju celih krtola ili sečenjem na četvrtine.",

AB  - Various biological characteristics of weed seeds were investigated. Weed seeds differ in many aspects from those of agricultural seeds. The difference results from a centuries-long struggle against the forces of nature, and especially from human activities aimed at controlling them. Weed seeds differ from those of agricultural crops regarding their biological (anatomical, morphological, physiological), and physical characteristics. The biological characteristics especially include: seed production, irregularity of maturing periods, seed viability, dormancy and germination intervals while the physical characteristics of weed seeds relate to: seed and fruit shape, size, character of the seed surface, absolute and specific mass, etc. Knowing the biological characteristics of weed seeds has great practical value both for forecasting weediness of a particular crop, and for planning and applying control measures, while data on the physical characteristics are relevant to the expansion of weeds, their identification and steps to be taken to acquire pure agricultural seeds. Research of the mechanisms of genetic, physiological and biological control of different phenomena and processes in weed seeds could prove invaluable for creating new cultivars and hybrids of agricultural crops.
AB  - U radu se razmatraju osnovne biološke karakteristike semena korovskih biljaka (produkcija, neravnomernost sazrevanja, dugovečnost i životna sposobnost, klijanje, periodičnost klijanja, primarna i sekundarna dormantnost semena). Posebno je ukazano na rezerve semena u zemljištu naročito u uslovima jake zakorovljenosti, raspored semena u zavisnosti od sistema obrade, kao i uticaj različitih faktora i mera na količine semena u zemljištu. Ukazuje se i na zakonitosti i mogućnosti upravljanja ovim procesima, kako bi se, na osnovu toga, moglo znati kada i koliko semena će klijati u određenim klimatskim i zemljišnim uslovima.
