The initial growth of sugarcane plants is the beginning and subsequent development, therefore by providing fertilizers that match the needs of the plants can increase the productivity of sugarcane plants. In sugarcane cultivation, ZA is the fertilizer that must be applied because it does not have an impact on reducing sugar levels (yield), in contrast to just giving urea fertilizer. The purpose of this study was to determine the effect of ZA dosing on the early growth of sugarcane plants. This research was carried out in the field using a randomized block design (RBD) consisting of one factor repeated four times. ZA fertilizer dose treatment factor: B0 = Without giving ZA, B1 = Giving a dose of 150 Kg ZA / Ha, B2 = Giving a dose of 300 Kg ZA / Ha, B3 = Giving a dose of 450 Kg ZA / Ha, B4 = Giving a dose of 600 Kg ZA / Ha, and B5 = Giving a dose of 750 Kg ZA / Ha. ZA fertilizer dose of 600 kg / ha showed the best treatment for the percentage of shoot growth, which was 76.25%, plant height was 53.00 cm, number of leaves was 14.12 strands. Then the dose of ZA fertilizer 600 kg / ha showed the best treatment for the number of tillers, namely 7.43 stems, stem diameter of 15.82 cm.</p>2024-01-31T00:00:00+00:00##submission.copyrightStatement##https://ojs.unud.ac.id/index.php/agrotrop/article/view/113427 Respon Pertumbuhan dan Hasil Terung Ungu (Solanum melongena L.) pada Konsentrasi dan Interval Waktu Pemberian Air Kelapa2024-02-28T06:53:23+00:00I Wayan Krisnayogi Anandamurtigedewijana@unud.ac.idGede Wijanagedewijana@unud.ac.idI Nyoman Gede Astawagedewijana@unud.ac.id<p><strong>Growth Response and Yield of Purple Eggplant (<em>Solanum melongena</em> L.) on Concentration and Time Interval Giving Coconut Water. </strong>The production of purple eggplant (<em>Solanum melongena </em>L.) which is still quite low can be overcome by the use of growth regulators in plant cultivation activities. This study aims to determine the effect of giving coconut water concentration and time intervals to increase the growth and yield of purple eggplant. This study used a factorial Randomized Block Design with 2 factors; first factor: concentration of coconut water 0%, 15%, 25%, and 35%; second factor: time interval of giving coconut water once every 4, 5, 6, and 7 days; with 3 repetitions. The observed variables are; Plant height (cm), Number of leaves (pc), Leaf area (mm2), Leaf chlorophyll, At the time of flower emergence (dap), Number of fruit per plant (pc), Fruit weight per plant (g), Fruit length (cm), Diameter of fruit (mm), Weight of fruit per fruit (g), Oven dry weight of fruit (g), Fresh weight of stover (g), Dry weight of stover (g). The results showed that the concentration and interval of administration of coconut water had a very significant interaction on flowering age and significantly on fruit diameter and fruit weight per fruit in the combination treatment which consisted of 15% coconut water and was given once every 5 days; giving coconut water has a very significant effect on plant height (71.17 cm), number of leaves (25.33 strands), and fruit oven dry weight (1.09 g), where the best treatment is by giving 15% coconut water; the timing of administration of coconut water had a very significant effect on fresh weight of stover (335.92 g) once every 6 days and had a significant effect on fruit oven dry weight (8.50 g) once every 4 days.</p>2024-01-31T00:00:00+00:00##submission.copyrightStatement##https://ojs.unud.ac.id/index.php/agrotrop/article/view/113428 Uji Efek Inokulan Pelet dan Kapsul Trichoderma harzianum terhadap Kandungan Resin dalam Kayu Gaharu Pada Lahan Berbeda2024-02-28T07:05:41+00:00I Made Megamademega@unud.ac.idNi Luh Kartinimademega@unud.ac.idI Gede Suranjayamademega@unud.ac.id<p><strong>Testing the Effect of <em>Trichoderma harzianum</em> Pellet and Capsule Inoculant on Resin Content in Agarwood Wood on Different Lands.</strong> Resin is a secondary metabolite compound produced by agarwood plants due to injury or infection by microbes. The formation of gaharu resin is influenced by the genetics of the resin-producing tree, the type of inducing microbe, the environment and the length of the resin formation process in gaharu. Previous research showed that inoculant pellets and <em>Trichoderma harzianum</em> mushroom capsules could increase the resin content in agarwood in the Dauhpuri Marga Village experimental garden. This research aims to prove the effect of inoculant in <em>Trichoderma harzianum</em> mushroom pellet and capsule packaging on the resin content in agarwood in several different fields. This research is an experimental research with a factorial pattern RCB design. The first factor is the type of inoculant packaging with 3 levels, namely: F0 (without inoculant), Fp (pellet inoculant), Fk (capsule inoculant). The second factor is land type consisting of 3 levels: Kl (Klungkung), Mg (Marga), Sl (East Selemadeg). The parameters observed were: color of agarwood, aroma of agarwood, resin content in agarwood. Quantitative data from observations/measurements are analyzed statistically using variance analysis, if significant occurs, it is continued with the Duncan Test. The research results showed that the type of inoculant packaging had a significant effect on the resin content in agarwood, but the type of land had no significant effect on the resin content in agarwood. This proves that <em>Trichoderma harzianum</em> fungus pellet inoculant can increase the resin content in agarwood on various different fields.</p>2024-01-31T00:00:00+00:00##submission.copyrightStatement##
