Managing water distribution in irrigation canals aims timely and in needed quantity implementation of supplies of water to irrigated area without excessive spillage i.e. at reduced conveyance loss and adequate water use for irrigation of the crops. This article analyzed existing management practice of water distribution in irrigation canal in view of efficiency. The study was carried out for an existing main irrigation canal. The operational water loss was evaluated by indirect quantitative approach. Hydraulic simulation model of the irrigation canal was created using hydraulic software HEC-RAS. Changes in hydraulic conditions due to existing structures along the canal course were taken into account in the model. The water operational loss was determined by simulation with HEC-RAS model in steady state conditions. The model was used to study the influence of the operating conditions on the size of loss. Results obtained show the influence of the management practice of the water distribution and operation conditions and maintenance of the canal on the magnitude of operational loss.

In this study, the influence of two different paddy harvesting methods (manual harvesting and combine harvesting) on paddy yield, head rice yield and white rice yield was investigated. Field trials were set up in three different locations in the rice producing regions Kocani, Cesinovo-Oblesevo and Stip under the standard production technology, adopted in the entire Macedonian rice production. Two Italian introduced varieties (San Andrea and Onice) were included in the trials. Samples were taken from the treatments with different methods of harvesting (manual and combine harvesting) from which the paddy rice yield data were collected directly. In order to determine the head rice yield, laboratory milling of paddy grains was performed on a paddy quality testing machine (three average samples of 100 g per treatment, duration of milling 1,40 min.). On the base of the data for paddy rice yield and head rice yield, the white rice yield was estimated. According to the results obtained, the highest paddy rice yield (11,925.67 kg ha -1 ) as well as the highest white rice yield (6,710.57 kg ha -1 ) were achieved in the treatment with manual harvesting in Kocani region (San Andrea variety). The highest head rice yield (65.80 %) was determined in the treatment with manual harvesting in Stip region (Onice variety), while the lowest head rice yield (43.90 %) was in the treatment with combine harvesting of the variety Onice in Kocani region. In general, the method of manual harvesting resulted in higher values of paddy yield, head rice yield and white rice yield compared to the method of mechanized, combine harvesting in all the examined treatments (two varieties, three locations).
研究了两种不同的水稻收获方式(人工收获和联合收获)对水稻产量、抽穗产量和白米产量的影响。在科卡尼、切西诺沃-奥布列塞沃和斯蒂普三个水稻产区的不同地点进行了田间试验，采用了整个马其顿水稻生产中采用的标准生产技术。两种意大利引进品种(圣安德烈亚和奥尼斯)被纳入了试验。采用不同的收获方式(手工和联合收获)采集样品，直接收集水稻产量数据。为了确定抽穗产量，在水稻质量试验机上进行了水稻籽粒的实验室碾磨(3个平均样品，每次处理100 g，碾磨时间1,40 min)。在水稻产量和抽穗产量的基础上，对白米产量进行了估算。结果表明，科卡尼地区(圣安德烈品种)的水稻产量最高(11,925.67 kg ha -1)，白米产量最高(6,710.57 kg ha -1)。在Stip地区，手工采收处理的抽穗产量最高(65.80%)，而在Kocani地区，联合采收处理的抽穗产量最低(43.90%)。总的来说，在所有试验处理(2个品种，3个地点)中，人工收获方法的水稻产量、抽穗产量和白米产量均高于机械化联合收获方法。

On the territory of the Vojvodina Province, the most common cause of soil salinization is the water in the first aquifer which is frequently saline and/or alkaline above the critical level. In this study, we analyzed water from the first aquifer sampled in locations classified as solonchaks in the soil map of Vojvodina (25 locations) and subsequently classified again into solonchak (5 locations), or reclassified into solonetz types of soil (9 locations) from the halomorphic order. The remaining eleven locations belonged to the soil types from the automorphic and hydromorphic order. Processes of desalinization and soil type change have occurred in these locations due to human activities (including the construction of drainage canals). But, based on salt or alkali levels above the critical and the quality of water in the first aquifer (especially high to very high sodium levels), it was concluded that there exists a serious risk of further continuous salinization and/or (especially) alkalization of the root zone of agricultural crops.

The human role in bioecological examinations of codling moths is of crucial importance for the integral protection of pome fruit and the production of healthy and safe food. The codling moth (Cydia pomonella L.) is one of the most significant apple pests in terms of causing the diminished yield and poorer fruit quality in apples. As such, the codling moth requires daily monitoring by agricultural producers. The aim of this research was defined by the need for establishing the presence of codling moth natural enemies and the estimation of their codependence in apple plantations with various methods of protection. The examinations were carried out on the territory of Southern Serbia from 2005 to 2008. During the research, the standard entomological methods, such as pheromone traps, branch beating and placing bands around tree trunks, were used to track the presence, number and population dynamics of the codling moth and its natural enemies. The research results revealed the dominant role that the anthropogenic factor has in many segments of the integral apple protection and the production of high-quality apple fruit. Faunistic researches are inevitable for the correct determination of human actions, due to the clear composition of autochthonous natural enemies of the codling moth. The natural enemies of the codling moth whose presence was determined during the research belong to the following orders: Hymenoptera, Diptera, Dermaptera, Neuroptera, Coleoptera and Heteroptera. The analysis that has examined the human influence on the autochthonous natural enemies of the codling moth also contributes to the preservation of biodiversity and agrobiocenosis, as well as to the production of high-quality, safe

The traditional planting system of rice in the Republic of Macedonia is wet direct seeding (hand broadcasting of seeds into pre-standing water in the fields). In this paper, the effects of different planting methods of rice (wet seeding as well as dry seeding by using seed drills) on productivity and quality of rice are presented. Field trials were set up at the Experimental Station of the Institute of Agriculture – Skopje, locality Mishjak, Kocani region, with two varieties (San Andrea and Onice) included. The following planting systems were explored: 1. wet direct seeding, with seeding rate of 250 kg seeds per ha (control); 2. dry seeding, 150 kg seeds per ha; 3. dry seeding, 200 kg seeds per ha. During the harvesting, the number of tillers per m 2 , biological yield, paddy rice yield, head rice yield and white rice yield were analyzed. The highest number of tillers per m 2 (San Andrea 383.00 and Onice 731.33) and the highest average paddy yield (San Andrea 11,780.00 kg ha -1 and Onice 10,113.33 kg ha -1 ) were achieved in the control. The highest biological yield in Onice (21,493.33 kg ha -1 ) was found in the control, while in San Andrea (20,650.00 kg ha -1 ) in the treatment dry seeding, 150 kg seeds per ha. For the head rice yield, the highest percentage was determined in the control (San Andrea, 54.57%) and in the treatment dry seeding, 150 kg seeds per ha (Onice, 66.72 %). Both varieties (San Andrea with 6,428.35 kg ha -1 and Onice with 6,143.83 kg ha -1 ) reached the highest white rice yield in the control. In general, in the treatment dry seeding with 200 kg seeds per ha, the higher values of number of tillers per m 2 , paddy yield and white rice yield were assessed, compared to the treatment dry seeding with 150 kg seeds per ha, in both varieties.
马其顿共和国传统的水稻种植系统是湿法直接播种(将种子用手播撒到田间的预积水中)。本文介绍了水稻不同种植方式(湿播和干播)对水稻产量和品质的影响。在科卡尼地区Mishjak地区斯科普里农业研究所实验站进行了田间试验，包括两个品种(San Andrea和Onice)。探索了以下几种种植制度:湿法直接播种，每公顷播种量250公斤(对照);2. 干播，每公顷150公斤种子;3.干播，每公顷200公斤种子。在收获期间，对分蘖数、生物产量、水稻产量、抽穗产量和白米产量进行了分析。对照的分蘖数最高(圣安德烈383.00和奥尼斯731.33)，平均水稻产量最高(圣安德烈117800.00 kg ha -1和奥尼斯10113.33 kg ha -1)。对照的生物产量最高的是Onice (21,493.33 kg ha -1)，而干播处理的San Andrea (20,650.00 kg ha -1)，每公顷150 kg种子。在抽穗稻产量方面，对照(圣安德里亚，54.57%)和干播处理(每公顷150公斤，66.72%)的比例最高。两个品种(圣安德里亚6,428.35 kg ha -1和奥尼斯6,143.83 kg ha -1)在对照中均达到最高的白米产量。总的来说，在两个品种中，每公顷200公斤干播处理的分蘖数、水稻产量和白米产量均高于每公顷150公斤干播处理。

The morphological properties that characterize the type of tobacco or the variety in one type are known as qualitative and quantitative. The quantitative properties are regularly conditioned from the impact of a larger number of genes and also they depend from the environment factors. The investigations are done in 2015 on experimental field in the Scientific Tobacco Institute in Prilep, with four repetitions with following varieties: Posejdon (control), BD-1, B-1246 and one new perspective line DP-1710. The aim of this investigationes is to show the variability of the most important quantitative properties: height of the plant with inflorescence, the number of leaves per plant and the length and width of the biggest and the smallest leaf from the middle harvesting belt in tobacco type Burley. The results from the research are processed statistically by these parameters: average value (x)̄, average value error (Sx ), standard deviation (S), variation coefficient (CV) and variation width (WV). From the research, we established that the subject varieties are stable enough, the variability is very low because everywhere the variation coefficient was lower than 10%. However, the newly created line DP -1710 is with the slightest variation in the tested properties. Among other things, it is on average the highest (x ̄= 188 cm) and has the largest leaves (x ̄ = 63 cm), which is a positive feature in coarse tobacco of this type.
