Pakcoy is a type of mustard plant that is quite popular with the community, it is very suitable to be cultivated considering the need for vegetables is quite large. The community's need for fresh and pesticide-free vegetables is a choice now in line with the community's understanding of a healthy diet. Alternatives to fulfillment are chosen by planting with hydroponic media. Hydroponics is a substitute for soil media that can be used to grow vegetable crops. The presence of hydroponics is expected to be able to overcome the narrowing of agricultural land and reduce the use of pesticides considering that pesticides greatly affect human health and the environment.   This study aims to determine the effect of nutritional doses of AB mix agrifarm and age of seedlings and their interactions on the growth and yield of pakcoy plants, this study is carried out in the experimental garden of the Faculty of Agriculture, Tabanan University which began on 9 December 2018 until 12 January 2019.   The study used a Randomized Block Design (RBD) consisting of two factors. The first factor is the nutritional dose of AB mix agrifarm (N) which consists of three dose levels, namely the dose of 850 ppm, 1050 ppm and 1250 ppm. The second factor is the age of seedlings (U) which consists of two seedling age levels, namely the age of seedlings 1 week and 2 weeks. Each treatment is repeated four times.   The results of the study obtained the interaction of dose agrifarm treatment with seed age showed a very significant effect (p 1 0.01) on all parameters except for the parameters of the number of leaves aged 35 days old which showed no significant effect (p 5 0.05). The economical wet weight of plant-1 and BKO of the highest yield of 1-crop yield is produced in the combination treatment of N3U, which amounted to respectively 244.09 g and 78.10g or increased respectively by 57.78% and 293.85% compared to results the lowest produced by the combination treatment of N1U1 is 154.71g and 19.83g

The research has been conducted to determine the effect of potato waste compost + cattle rumen to increase soil fertility and the product of several vegetable kinds. The research location was in Desa Candikuning, Bedugul, Bali with altitude was 1,247 m above the sea level. The climate types including B3 with 7-8 months on wet and 4 -5 months on dry. The research was conducted from May to October 2014 using a Randomized Block Design of nested pattern factorial. The treatment was attempted was potato waste compost + cattle rumen towards several kinds of vegetables, each treatment was replicated three times. The research results of nutrient consist of potato waste compost + cattle rumen showed C-organic was 6.940% N-Total, 0.310% P-provided, 23.69 ppm and 0.340% K-Total. The application of potato waste compost + cattle rumen increased a soil of C-organic from 1.840% to be 3.75%, N-Total of soil increased from 0.159 to be 0.260%, P-Provided of increasing soil from 437.180 ppm to be 2900 ppm and K-Total of increasing soil from 0.04% to be 0.08%. the treatment of potato waste compost + cattle rumen showed the significance increasing for five kinds of vegetables were attempted. Four vegetable types crops were attempted, namely lettuce, green vegetables, phak choy, and spinach unplug showed a variety improvement, it was a very real and not real. However, on Kaylan, potato waste composting + cattle rumen was no significant effect.

Ground kale (Ipomoea Reptans Poir) is one of the agricultural commodities that can be traded at a relatively expensive price. Spinach plants that are relatively resistant to drought andhave a broad adaptability to varius growing environmental conditions, estimated at 2-3 times per year so that the cash flow of the vegetable business will be faster. An incease in demand with demands for better quality vegetable commodities, as well as more guaranteed survival. The estimated annual vegetable demand rate of 8% is good for consumption in the contry, import substitution and in increasing export opportunities. Regulating plant density to a certain extent, the plants can utilize the growing environment efficiently, and the inorganic fertilizer becauseit has a Nitrogen (N) content of 46%. Where nitrogen is a major component of varius important substances in plant. About 40% of the protoplasm content consists of nitrogen compounds used by plants to form amino acid  compounds that are comperted into proteins, chlorophyll,nucleic acids and enzymes.This study was conducted to determine the effect of spacing and dose of N as well as its intrinsic growth and yield of ground water spinach plants,and was carried out in the Subak Tungkub Mengwi region, Mengwi Village, Mengwi District, Badung Regency, with a height of ± 400 m above sea level. The study began from December 8, 2020 until Januari 5, 2021 for 28 days from planting seeds to harvest. This study uses a randomized blok design (RBD) consisting of two factor. The first factor is plant spacing (J) and the second factor is the dose of Urea (U), each treatment is repeated three times.The economical oven dry weight of plants at the distance of plant spacing with the average oven dry weight of economic clump-1 was 5,25 g, with the highest value indicated in the treatment (J1) was 5,34 g while the highest value of Urea dose was shown at dose (U2) of 7,74 g increasing 23,84% compared to the oven dry weight of the lowest clump-1 economy of 6,25 g

Praktek mengkombinasikan pupuk kandang ayam dengan NPK merupakan kebiasaan petani kentang di desa Candikuning, Tabanan, Bali. Petani mengeluarkan biaya cukup besar rata-rata 10 Juta untuk penanaman 1 ha kentang untuk mendapatkan kotoran ayam ini. Kompos berbahan baku residu kentang akan menjadi alternatif pengganti pupuk kandang ayam. Penelitian telah dilakukan bertujuan membandingkan kebiasaan petani dengan aplikasi kompos residu kentang dan NPK terhadap perbaikan karakteristik tanah (sifat fisik, kimia dan biologi) dan pengaruhnya terhadap peningkatan hasil kentang.  Hasil percobaan laboratorium menunjukkan bahwa pemberian 100% kompos residu kentang menyebabkan peningkatan KTK, C-organik, P-tersedia dan K-tersedia dengan nyata masing-masing sebesar 170,57%; 172,62%; 69,71% dan 208,20% dibandingkan tanpa pupuk, tetapi tidak menyebabkan meningkatnya KB. Perlakuan 100% kompos residu kentang meningkatkan total jamur secara nyata dibandingkan kontrol. Perbaikan karakteristik tanah menyebabkan meningkatnya berat total umbi segar rumpun-1 maupun ha-1 masing-masing 345,39% dan 157,84% akibat pemberian 100% kompos dibandingkan tanpa pupuk. Perlakuan 100% kompos  maupun kombinasinya dengan NPK (75%, 50% dan 25%) dan kombinasi pupuk kandang ayam dengan NPK (75%, 50% dan 25%) juga nyata meningkatkan indeks panen hampir lebih dua kali lipat (200%) dibandingkan kontrol.

The purpose of this study was to determine the effect of bokashi fertilizer dose and seedling age and their interaction on the growth and yield of celery plants. This research was conducted in Banjar Candikuning 2, Candikuning Village, Baturiti District, Tabanan with an altitude of 1255 m above sea level. The study was conducted from November 22, 2021 to January 26, 2022. This research is a pot experiment using a basic design, namely Randomized Block Design with a factorial pattern. The treatments given were the dose of bokashi fertilizer and the age of the seedlings, each treatment was repeated three times.The interaction between bokashi fertilizer dose treatment and seedling age (N x U) had a very significant effect (P < 0.01) on most of the observed parameters, except for the oven dry weight of the top of the plant, oven dry weight of the bottom of the plant and oven dry weight. total plants that showed no significant effect (P 0.05). The highest total plant fresh weight was obtained at a dose of 1.0 kg of bokashi fertilizer at the age of 25 days after seedling (N2U1) of 7.40 g, an increase of 482.67% from the lowest yield of treatment with a dose of bokashi fertilizer without fertilizer at the age of 30 seeds. hss (N0U2) which is 1.27 g.Bokashi fertilizer treatment with a dose of 1.0 kg (N2) gave the highest total plant oven dry weight of 0.44 g, while the lowest was obtained in the treatment without fertilizer (N0) only 0.09 g or an increase in yield of 388.89 %. The seedling age treatment gave the highest total oven dry weight of the plant at the seedling age of 25 hss (U1) which was 0.35 g or an increase in yield of 45.83% compared to the 30 hss (U2) seedling age treatment which gave the total oven dry weight of the plant only. of 0.24 g
