Abstract

Pemupukan berpengaruh positif terhadap pertumbuhan dan produksi tanaman kedelai. Pupuk kompos merupakan pupuk organik yang diberikan kedalam tanah dapat meningkatkan unsur hara baik makro maupun mikro. Selain pemberian pupuk kompos dapat juga ditambahkan pemberian pupuk urea (sebagai pupuk anorganik) yang dapat memberikan unsur hara N bagi tanaman. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan dosis pupuk (kompos dan pupuk urea) dengan varietas terhadap pertumbuhan tanaman kedelai, serta menentukan varietas unggul yang terbaik terhadap pertumbuhan kedelai. Penelitian ini menggunakan rancangan acak kelompok (RAK) faktorial, dengan factor 1 dosis pupuk, D0: kontrol, D1:kompos 5ton/ha, D2 :kompos 10 ton/ha, D3: urea 25 kg/ha, dan D4 : urea 50 Kg/ha. Faktor 2 yaitu varietas dengan V1 : Varietas Anjasmoro dan V2 : varietas grobogan. Hasil penelitian menunjukkan bahwa pemberian pupuk kompos dan pupuk urea dapat meningkatkan pertumbuhan tanaman kedelai, dan juga mempercepat umur berbunga tanaman kedelai. Varietas grobogan memiliki umur berbunga paling cepat yaitu 32.33 hari dibandingkan dengan varietas anjasmoro. Peran pupuk kompos dan urea dalam penelitian meningkatkan unsur N tersedia bagi tanaman

Abstract

Pakcoy (Brassica rapa L.) or commonly called mustard spoon includes vegetable plants that are heat resistant, so that they can be planted in the lowlands to highlands The production of packcoy plants experiencing ups and downs in 2010 is the peak production of 141.25 quality / ha and continues to decline to 2014 became 114.35 quality / ha. Efforts to increase packcoy production can be done by using organic fertilizers from agricultural waste, manure, green manure, human waste, and compost instead of nutrient sources. This study aims to determine the response of growth and production of Pakcoy plants to the provision of NASA POC organic fertilizer. This study uses factorial randomized block design consisting of 2 treatment factors, namely: Chicken Cage Organic Fertilizer (A) which consists of 3 levels, namely: A0 = 0 tons / ha, A1 = 15 tons / ha (158 g / polybag), A2 = 30 tons / ha (316 g / polybag). NASA POC concentration (N) consists of 4 levels, namely: N0 = 0% (control), N1 = 1 cc / liter of water, N2 = 2 cc / liter of water, N3 = 3 cc / liter of water. The results showed that NASA's POC showed a significant effect on pakcoy plant height, the use of liquid organic fertilizer dosage (2cc / ltr) had a significant effect on plant height. The highest pakcoy plant height is found in the treatment of N2 (2 cc / ltr) of 25.50 cm. The net weight per plot was obtained at the N2 treatment of 262.92 grams

Abstract

In The effort to increase soybean production, various treatments can be applied, one of which is cultivation in which spacing between the plants is adjusted to obtain ideal production. Spacing is determined depending on seed growth, soil fertility, season, and the variety of plants. Apart from spacing, the use of compound fertilizer is also very important in the growth and production of soybean plants. One way to reduce production costs and improve the soil and crop yield quality is applying a compound fertilizer such as NPK Mutiara (16:16:16). NPK (16:16:16) fertilizer has a balanced composition of nutrients and dissolves slowly until the end of the growth process. The purpose of this study is to discover the effect of plant spacing and dosage of NPK Mutiara (16:16:16) fertilizer, and the best interaction between spacing and NPK Mutiara (16:16:16) fertilizer dosage, on the growth and yield of soybean plants (Glycine max (L) Merrill). The research was conducted in a farmer’s experimental garden, in Jalan Eka Suka 11, Pangkalan Mansur Village, Medan Johor District, at a height of ± 15 meters above sea level. The method used is a factorial randomized block design (RBD) with the first factor being plant spacing, and the second -factor being NPK fertilizer dosage. The results of the research show that NPK fertilizer dosage and plant spacing both have a significant effect on plant height and the number of branches. The highest plant height, 75.50 cm, was obtained using the treatment J3 (40 cm x 40 cm spacing), compared with the other two treatments. The lowest plant height, 61.08 cm, was obtained using the treatment J1 (30 cm x 30 cm spacing). The highest number of branches was seen in the treatment K3, with 7.00 stalks, while the lowest number of branches was found in the treatment K0, with 6.03 stalks.
