Determining the appropriate planting arrangement and plant density leads to better productivity of resources and increased yield per unit area. In this regard, an experiment was conducted in the Ardabil agricultural and natural resources research and education center (Moghan) during the 2021 crop year. This experiment uses a strip plot design based on randomized complete blocks with four replications. Its main factor is the effect of planting rows at a spacing of 30, 45, and 60 cm with planting spacing of 5, 8, 11, and 14 cm serving as the subfactor. According to the results, by increasing the ...Более
Salinity is an important abiotic stress factor that negatively affects plant growth and yield. The study, the effect of microbial fertilizer containing Bacillus subtilis bacteria, commercially named Subtima, on salt stress in pepper was observed. Two different saline solutions (100 mM and 200 mM) were prepared to create salt stress in the plant growing medium. The fertilizer solution was applied to the plants in 4 different concentrations (300, 400, 500 and 600 ppm) from the leaves in the form of a spray. Morphological parameters such as plant height, stem length, leaf length, leaf width, and ...Более
PGRs such as paclobutrazol, daminozide, chlormequat and propiconazole help to alter various growth characteristics of plants and they are used commonly in the modern production system of ornamental plants. The objective of this work was to evaluate the effects of the optimum dose, decreasing and increasing amounts of the optimum dose of paclobutrazol, daminozide, chlormequat and propiconazole used in the modern production system of zinnia (Zinnia elegans Jacq.) vegetative growth parameters and flowering in a greenhouse experiment. Plant height was reduced with the administration of 2 g L-1 of ...Более
Nutrient uptake of chard under well-watered and drought conditions with different NO applications were investigated in this research. NO solutions were prepared with four doses (0, 50, 100, 150 and 200 µM) of sodium nitroprusside as a nitric oxide source and exogenously applied on only seeds (s) or together with seed and foliar (sf) of chard under different levels of drought according to 100% (control), 67% and 33% of the water required to reach field capacity. Nutrient uptake drastically decreased under drought stress. However, progressive effects of NO applications on nutrient uptake have be ...Более
Turkey is one of the most important countries in the production of confectionary pumpkin. The aim of the study is to reveal the amount of some mineral elements in seed coat and the seed of confectionary pumpkin candidates which gathered from different regions of the country and reached in S5 level. In the present study, a total of twenty-seven pumpkin genotypes which were self-pollinated to the level of S5 and two local population characterized genotypes were used as plant material. Contents of P, K, Ca, Fe, Mg, Mn, Cu, S and Zn minerals were determined in the seed coat and seed, separately. R ...Более
Araştırma 2014-2015 vejetasyon döneminde, Türkiye’de Trabzon İli Düzköy İlçesi Beypınarı doğal merasında, farklı azot ve fosfor dozlarının meranın ot verimi, ot kalitesi ve botanik kompozisyona etkilerini belirlemek amacıyla yürütülmüştür. Deneme tesadüf bloklarında faktöriyel deneme desenine göre üç tekrarlamalı olarak kurulmuştur. Çalışmada azotun 5 (0, 5, 10, 15, 20 kg /da) ve fosforun 3 (0, 5, 10 kg/da) kombinasyonu incelenmiştir.
Araştırma sonucunda, Karadeniz Bölgesi’nde yüksek rakımlı, buğdaygillerin baskın olduğu bir merada, azot ve fosforlu gübrelerin ot verimi, ot kalitesi ve botanik ...Более
