Implementation of triticale in nutrition of non-ruminant animals

Cognition of chemical composition and nutritive values of triticale grain as well as the effect of its application in non-ruminant animal nutrition were pointed out in this paper. There is a high level of proteins in the grain of triticale (2 to 3% more than wheat and 4% more than rye), with very beneficial amino acid composition, and is the reason for its usage in domestic animals nutrition. Nowadays, people are of the opinion that triticale is one of potential plant species with the brightest perspective in the production of food for domestic animals. Considering the increased production of triticale, some detail researching of its nutritional value is necessary due to the required evaluation of the role and significance in domestic animal nutrition based on triticale. Due to intensive plant breeding programs, there are new varieties of triticale in the market, distinctive by the higher yield and wide range of desired traits. As a result of this, triticale is becoming very attractive and is occupying larger portions of arable land. These review will show if there are some advantages of triticale compared to other cereals and how large the frame of these advantages is, as well as how it will affect the further spreading of triticale on arable land.Key words: Triticale, chemical composition, nutritive capacity, nutrition

Yield and chemical composition of soybean seed under different irrigation regimes in the Vojvodina region

© 2017, Czech Academy of Agricultural Sciences. All rights reserved. The goal of the present research is to determine an effective sprinkler irrigation strategy for soybean [Glycine max (L.) Merr.] in temperate climate conditions, in order to maximize yields and seed quality. A three-year field experiment with four different irrigation treatments was conducted on Calcic Chernozem in the Vojvodina region of Serbia. The irrigation regimes included: no irrigation; full irrigation (I100); and two deficit irrigation treatments -65% of I100 (I65) and 40% of I100. The irrigation treatments generally had a statistically significant effect on the increase of soybean yield and protein content. Irrigation did not have a significant effect on the oil content. In general, irrigation increased K, P, Mg, Mn, Cu, Zn and B concentrations and decreased Ca and Fe concentrations in soybean seed. The results show that irrigation with the largest amount of water (treatment I100) provided no potential benefit in terms of soybean yield and chemical composition. Treatment I65, which exhibited the most favourable watering conditions, is the best choice to maximize yield and ensure a good chemical composition of soybean under these agroecological conditions

How irrigation water affects the yield and nutritional quality of maize (Zea mays L.) in a temperate climate

© 2018, HARD Publishing Company. All rights reserved. Soil water deficit has an adverse effect on crop productivity and is one of the main limiting factors of global food security. Field experiments were conducted in Vojvodina, Serbia, to expand and improve knowledge about the effects of different levels of irrigation on maize grain yield and quality. The studied irrigation treatments were: full irrigation (I100), 75% (I75) and 50% (I50) of I100, and no irrigation (I0) – rainfed. The irrigation level affects maize grain yield; protein, starch, and oil content; and mineral composition. The results show that that yield decreases with increasing water deficit in three study years. On average, full irrigation results in the highest oil content and rainfed conditions in the lowest. The starch content increases and the oil content decreases with decreasing irrigation. Irrigation significantly increases the concentrations of K, Mg, Fe, Mn, and Zn, and reduces the Ca concentration compared to the rainfed treatment. A 25% water deficit (I75) has a positive effect on certain maize grain nutrients and the yield is significantly reduced. The highest grain yield and oil content are achievable with full irrigation. For good nutrientional quality of maize, treatment I75 can be proposed under similar soil and climate conditions

Effect of irrigation regime on yield and yield components of soya bean

This study examines the effects of different irrigation regimes on seed yield and yield components of sprinkler-irrigated soya bean [(Glycine max (L.) Merr.] under field conditions in 2006, 2007 and 2008 in Zemun Polje (Srem, Srbija). Four irrigation regimes: 80-85% (T1), 70-75% (T2), 60-65% (T3) of field capacity, and non-irrigated regime (T0) were evaluated each experimental year. The experimental design was a randomised complete block with four replications on a Calcaric Chernozem. Water stress (drought) during growing season in the non-irrigated treatment (T0) decreased plant physiological activity, vegetative growth, and productivity of soya bean. Irrigation treatments significantly (P < 0.01) influenced soya bean seed yield and yield components. The treatment T2 produced higher seed yield than T1 and T3. Irrigation regimes had statistically significant different effects on yield components such as the plant height at harvest, number of pods per plant, number of seeds per plant, mass of pod with seeds per plant, 1,000 seed mass and hectoliter mass of soya bean seeds. Yield reduction was mainly due to a lower number of pods and seeds per plant and lower seed mass. The T1 treatment had the highest plant height of soya bean in all three growing years. The results have shown that under water scarcity, the treatment T3 is an acceptable irrigation strategy to stabilize and increase soya bean yield in Srem and neighboring countries in the region, provided that this practice is not prevented by economic constraints.

Effects of deficit irrigation on grain yield and ear characteristics of maize

In the Vojvodina region, drought is an important factor limiting grain yield in maize. The aims of this research were to compare irrigation scheduling in maize (cv. ZP SC 684), and to evaluate grain yield and ear characteristics. A 3-year field experiment was carried out in the Vojvodina region, a northern part of the Republic of Serbia (384 mm of rainfall in the maize-growing period). Maize was subjected to four irrigation levels (rainfed - I0 and supply at 80-85% - I1, 70-75% - I2 and 60-65% - I3 of field capacity). The results indicated a large yearly variability, mainly due to a rainfall event at the flowering, fertilization and grain filling stages. A significant irrigation effect was observed for all the variables under study, with significant differences between the three irrigation treatments. The grain yield ranged between 8.73 and 16.33 t ha-1. The highest grain yield of maize (average of 15.08 t ha-1) was in the I1 treatment, while the non-irrigated (I0) treatment had the lowest yield (average of 10.20 t ha-1), a 35% grain yield reduction. With the decrease of irrigation water, the grain yield of maize decreased. The most distinctive impact the irrigation had on maize yield was during the warm and very dry growth period of the year of 2008. Maize in the Vojvodina region can be cultivated with acceptable yields while saving irrigation water and maximizing resource-use efficiency
