SUSYLOWATI susy_rusdi2@yahoo.com DELMA PERANISA noreplygphjournal@gmail.com <p>Celery is widely used as a flavoring, mixture, and decoration of food, as well as beneficial for health, but its production is relatively low. One way to improve the quality and quantity of celery yields is by providing cow urine Liquid Organic fertilizers (LOF). The experiment was carried out from August until October 2021 in Sempaja Selatan Urban Village, North Samarinda District, Samarinda, East Kalimantan. Single factor experiment, cow urine LOF&nbsp; concentration consisted of &nbsp;0, 150, 300, and 450 mL L<sup>-1</sup>, arranged in a Completely Randomized Design and replicated ten times. The variables observed increased in: plant height, number of stems, number of leaves; number of tillers, fresh weight, and dry weight of the plant. Data were analyzed by analysis of variance, followed by the Least Significant Difference test at a 5% significance level. The relationship between plant dry weight with LOF concentration was determined by orthogonal polynomial regression analysis and correlation. The results showed that the effect of LOFconcentration was significantly different in all observed variables. The concentration of 450 mL LOF L<sup>-1</sup> gave the best effect on the growth and yield of celery. The results of regression and correlation analysis obtained a linear and positive relationship. The regression equation for plant dry weight and LOF concentration is ŷ = 2.701 + 0.009x, correlation coefficient 0.9947, and coefficient of determination 0.9895.</p> 2022-10-02T17:05:37+00:00 ##submission.copyrightStatement## http://gphjournal.org/index.php/ar/article/view/734 EFFECT OF DIFFERENT CULTIVATION AGRO-METHODS ON YIELD AND QUALITY INDICATORS OF VIRGINIA-TYPE AROMATIC TOBACCO VARIETIES 2022-11-23T15:51:54+00:00 KAZIMOV GABIL qabil.adiloglu@yahoo.com ABDULLAYEVA NARGIZ noreplygphjournal@gmail.com ALIYEVA AMINAT noreplygphjournal@gmail.com MAHAMMADOVA SEVDA noreplygphjournal@gmail.com <p>It was talking about the influence of irrigation norms on the productivity of Virginia tobacco varieties and the choice of commodity types in Sheki-Zagatala region. Thus, the highest dry leaf yield is N<sub>45</sub>P<sub>120</sub>+20 tons of manure on the background of 120×40 cm in the food field, the 22,2 cent/ha was obtained at 70-80-50% irrigation norm, 24,3 cent/ha was at 70-80-60% irrigation norm, 24,9 cent/ha was at 70-70-60% irrigation norm; in the 110×40 cm food field and 26,4 cent/ha was obtained at 70-80-50% irrigation norm, 27,9 cent per 1 ha was&nbsp; at 70-80-60% irrigation norm, 26,3 cent/ha was at 70-70-60% irrigation norm; in the 90×40 cm food area 29,5 cent/ha was obtained at 70-80-50% irrigation norm, 30,1 cent/ha was at 70-80-60% irrigation norm, 27,7 cent/ha was at 70-70-60% irrigation norm.</p> 2022-11-23T15:51:10+00:00 ##submission.copyrightStatement##
