Abstract

The aim of this paper is to present the results regarding the yield and the yield components we have obtained at two triticale varieties studied under different preceding crops, different soil tillage conditions, and different nitrogen application conditions. In this respect, two triticale varieties (Tulus and Gorun 1) were studied under the following technological conditions: two preceding crop (sunflower and maize), two soil tillage (ploughing and harrowing), and six nitrogen application variants (0+0+0 kg.ha-1, 40+40+40 kg.ha-1, 40+80+0 kg.ha-1, 0+40+80 kg.ha-1, 0+80+40 kg.ha-1, and 0+120+0 kg.ha-1, respectively first application in autumn, before seedbed preparation, second application in spring, in the tillering growing stage, and third application in spring, in the two nodes growing stage). Researches were performed in a field experiment under rainfed conditions in the agricultural year 2013-2014. The field experiment was located on a reddish preluvosoil within the Experimental Farm Moara Domneasca (44° 29’44” North latitude and 26° 15’28.5” East longitude) belonging to the University of Agronomic Sciences and Veterinary Medicine of Bucharest. There were determined the yield at 14% moisture content, the number of ears per square meter, the yield components of the ears (ear length; number of fertile spikelets per ear; number of sterile spikelets per ear; number of grains per ear; number of grains per spikelet; grain weight per ear), and the yield quality (thousand grain weight, hectoliter weight, protein contend and starch content of the grains).

不同工艺条件下小黑麦籽粒产量及其构成因素
本文的目的是介绍我们在不同前茬、不同土壤耕作条件和不同施氮条件下对两个小黑麦品种的产量和产量组成进行研究的结果。在此方面,研究了2个小黑麦品种(图鲁斯和戈润1号)在以下技术条件下:2种前茬作物(向日葵和玉米),2种土壤耕作方式(翻耕和耙耕),6种施氮变异体(0+0+0 kg)。Ha-1, 40+40+40公斤。Ha-1, 40+80+0公斤。Ha-1, 0+40+80公斤。Ha-1, 0+80+40公斤。Ha-1和0+120+0 kg。Ha-1,分别在秋季第一次施用,苗床准备前,春季第二次施用,分蘖生长期,春季第三次施用,两节生长期)。研究在2013-2014农业年旱作条件下进行。田间试验位于布加勒斯特农艺科学和兽医大学的实验农场Moara Domneasca(北纬44°29 ' 44 "和东经26°15 ' 28.5 ")内的红色前土壤上。有确定收益率在14%含水率,每平方米的耳朵,耳朵的产量构成(耳朵长度;每穗可育小穗数;每穗不育小穗数;每穗粒数;每小穗的粒数;每穗粒重)和产量品质(千粒重、百升重、籽粒蛋白质含量和淀粉含量)。
