Abstract

Tomatoes are plants with a short life cycle, can grow as high as 1 to 2 meters. This plant has green, yellow and red fruits that are usually used as vegetables in cooking or eaten directly without being processed. Tomatoes have stems and leaves that cannot be consumed because they are still in the same family as potatoes and eggplants that contain alkaloids. The problems that arise today are unsuitable climate conditions and less supportive soil conditions. This is because cultivating tomatoes with soil temperatures that are too high can cause excessive evaporation so that the percentage of groundwater loss increases. This will have an impact on the inhibition of the nutrient absorption process. Therefore, it is necessary to make efforts to provide mulch and provide biological fertilizers. The aim of this research was to determine the effect of mulch type and arbuscular mycorrhiza dosage on the growth and yield of tomato plants. This research was carried out in Langsa City using a factorial group random design (RAK), namely the Mulch Type Factor with the notation (M) consisting of 4 levels, namely control, silver black plastic mulch, sugarcane bagasse mulch, rock mulch and Arbuscular Mycorrhiza dosage factor with the notation (F) consists of 4 levels, namely control, 5 gr/plant, 10 gr/plant, 15 gr/plant. The results of the research showed that the influence of the type of mulch had a significant effect on plant height, fruit weight and average fruit weight per plant as well as an interaction between the type of mulch and the dose of plant height and weight per fruit.Keywords: tomato plants, type of mulch, arbuscular mycorrhiza

Abstract

 ABSTRAKPermasalahan pada budidaya tanaman jagung manis belum tepat termasuk pada penggunaan dosis pupuk dan cara pemupukan yang tidak tepat. Kesalahan dalam pemupukan saat pemberian dapat mempengaruhi kualitas dan kuantitas jagung manis dimana unsur hara yang terdapat di dalam tanah akan berkurang. Oleh karena itu penelitian ini bertujuan untuk mengetahui respon pertumbuhan dan hasil jagung manis ( Zea mays sacharata Sturt.) terhadap dosis dan cara pemupukan NPK. Penelitian ini dilaksanakan di Kota Langsa dengan menggunakan rancangan acak kelompok (RAK) faktorial, yaitu Dosis Pupuk NPK yang terdiri dari 3 taraf yaitu 300 kg/ha, 400 kg/ha, 500 kg/ha, dan cara pemupukan NPK yang terdiri dari 4 taraf yaitu Pop up, Tugal, Sebar, Larikan. Hasil penelitian menunjukkan bahwa antara dosis NPK (300 kg/ha) dan cara pemupukan larikan dapat meningkatkan parameter pertumbuhan jagung manis. Kebutuhan unsur  Nitrogen (N) ,  Fosfor (P) , dan  Kalium (K ) untuk tanaman jagung yang diberikan secara tepat dan berimbang untuk pertumbuhan dan hasil tanaman.Kata kunci : Jagung manis, dosis pupuk NPK, cara pemupukan NPK
