All Mcal units were converted into Liter Diesel Oil Equivalent (LDOE), where 1.0 LDOE = 11.414 Mcal. Purposive sampling was used in determining the fitted characteristics and the number of respondents required across the 16 CBFM sites, where nine (9) dominant AFSs were identified. A total of 100 respondents were interviewed using a structured questionnaire. The relationships of predictors such as the direct, indirect and embedded energy inputs per AFS were analyzed using descriptive statistics. Means, percentages and sums were compared. The rubber+1based AFS obtained the lowest total energy inputs (TEI) at 5,790.5 Mcal ha-1 or equal to 507.3 LDOE ha-1, while the rubber+3based AFS obtained the highest TEI at 11,801.3 Mcal ha-1 (1,034.0 LDOE ha-1) compared to other AFSs such as the coconut+1based, mango-based, marang-based, lanzones-based, coconut+3based, rubber+2based and coconut+2based with individual TEI that ranged from 6,267.16-11,250.2 Mcal ha-1 (549.1-985.6 LDOE ha-1). Of the total TEI across the nine (9) AFSs, the direct energy input (DEI) contributed 1.6-5.4%, indirect energy input (IEI) 94.1-98.0% and embedded energy input (EEI) 0.3-0.5%, respectively. The TEI is the sum total of DEI, IEI and EEI where each was accounted from pre-land preparation (PLP), crop establishment (CE), crop care and maintenance (CCM), harvest and postharvest (HPH) activities. The high imputed cost on IEI was attributed to high usage of agrochemicals and labor which are identified as the ‘energy hotspots’ or the energy-intensive inputs. The high plant density and number of trees present within the system contributed significantly in the overall TEI. Understanding the significant contributions of various energy-intensive systems will guide policy makers and local planners to initiate an integrated farming approach with reduced energy inputs that is climate smart with higher economic potential for the upland environment in the City of Zamboanga.","PeriodicalId":310130,"journal":{"name":"American Journal of Agriculture and Forestry","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125424340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, only a part of the varieties can be directly compared with each other in terms of ecological stability, and the main grouping has to be carried out by comparing the behavior of samples with standard varieties under conditions of different years. Even well-studied varieties are not always suitable for such comparisons. When selecting the starting material for breeding, it is important not only to find forms with a high level of manifestation of quantitative traits, but also to minimize this level under unfavorable conditions for plant growth and development. The purpose of our research was to determine the stability and plasticity of collection samples of spring durum wheat of various ecological and geographical origins. Over the years of the research, the yield averaged 330.3 g/m2 and varied from 434.3 g/m2 (max) in 2015 to 188.5 g/m2 (min) in 2018. This indicates that the genotype and contrast weather conditions of the years significantly affect the yield of collection samples of spring durum wheat. Stable and plastic collection samples of spring durum wheat were identified for yield: 193 THKNEE 8 (Mexico) (bi = 1.02, S2di = 0.11), ARN AAZ-1.040 YRC-4M (Mexico) (bi = 1.35, S2di = 0.12), SHAG 21 / CASCA (Mexico) (bi = 1.07, S2di = 0.23), Hordeiforme 13-07 (Ukraine) (bi = 2.11, S2di = 0.31).

The use of high-quality seeds of the best varieties being adapted to local growing conditions is an important requirement for increasing wheat yields. The purpose of this research was to establish the influence of preceding crops and sowing dates on yield and seed sowing quality of winter bread wheat varieties. On average, maximum yield capacity in 2016–2018 was obtained in the variety Trudivnytsia myronivska (7.41 t/ha) when sowing on 15 September after green manure, the minimum yield was in the variety MIP Kniazhna (4.03 t/ha) when sowing on 15 October after soybean as preceding crop. Shifting the sowing dates to later ones led to decrease in yield capacity by 0.97 and 0.62 t/ha after the preceding crops green manure and soybean, respectively. After the preceding crop soybean, the maximum yield (5.77 t/ha) was formed by the variety MIP Valensiia when sowing on 25 September. By ANOVA it was found that the level of wheat yield was the most significantly affected by hydrothermal conditions of the year (63%), the interaction “preceding crop  conditions of the year” (12%) and preceding crop (11%). It was revealed that an increase in weight of 1000 seeds in the varieties on average was 3.9 g after the preceding crop green manure in comparison with the preceding crop soybean. There was a slight effect of preceding crops and sowing dates on seed vigor and laboratory germination. These rates were slightly higher for early and optimal sowing dates after green manure as compared with the soybean. Thus, it was confirmed that in the Right-Bank Forest-Steppe green manure is the best preceding crop for seed production, especially for growing pre-basic seeds, while 15 and 25 September are the best sowing dates. For the preceding crop soybean, when sowing on 25 September and 05 October, the yield of wheat varieties was the highest in comparison with sowing on 15 October. Locations of winter wheat seed crops after the best preceding crops in crop rotation and optimal sowing dates will promote the most efficient using of climatic and anthropogenic factors, increase grain yield per area unit, and improve seed sowing quality.","PeriodicalId":310130,"journal":{"name":"American Journal of Agriculture and Forestry","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116741765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The productivity of spring wheat plants mainly depends on the growing zone (29.2%), hydrothermal vegetation conditions (16.3%), as well as their interaction (27.1%).

Remeslo Myronivka Institute of Wheat) and Polissia (Nosivka Plant Breeding and Experimental Station). Methods of descriptive statistics and analysis of variance were used for data statistical processing. For all three years during active plant vegetation the hydrothermal coefficient was 0.9–1.2 in the Forest-Steppe zone and in the Polissia zone it was 1.0–1.3. Winter wheat yield formation was negatively affected by the conditions of 2016-17 in the Forest-Steppe zone and 2017-18 in Polissia zone according to the relative environmental index (REI = 66 and 73, respectively). The analysis of hydrothermal conditions of different agro-climatic zones of winter wheat cultivation indicates on significant variation of the influence of these conditions on individual stages of plant development. This made it possible to identify varieties with high ecological plasticity which are able to respond less to fluctuations in environmental conditions. Using analysis of variance, it was found that winter wheat yielding capacity was significantly influenced by the factors “Zone” and “Year” (28.8, 22.9%, respectively), but theу most (36.4%) it was influenced by the interaction “Year × Zone”, this indicates a significant difference in the impact of hydrothermal conditions on this trait depending on the agro-ecological zone of cultivation.

Correlation analysis showed a strong positive relationship between the weight of grain from the plant with the weight of grain from the ear (r = 0.78), the average - with the number of grains from the plant and ear and the weight of 1000 grains (r = 0.47; 0.63 and 0.37) and weak - with starch content (r = 0.14).
