Potted chrysanthemum plants are very popular with the public because of their various colors, sizes and shapes. The experiment was aimed to give the concentration of potassium nitrate (KNO3) which had a good effect on the growth and yield of potted chrysanthemums cyra agrihorti varieties. The experiment was carried out from March to May 2021 in Cimeta Village, Tugumukti Village, Cisarua District, West Bandung Regency at an altitude of 1312 m above sea level. The experiment method used complete randomized design (CRDB) of six treatments and four replications. The KNO3 concentration treatments used were A = 0 g/liter, B = 1 g/liter, C = 2 g/liter, D = 3g/liter, E = 4 g/liter, and F = 5 g/liter. The results showed that the KNO3 concentration treatment had an effect on increasing the growth and yield of potted chrysanthemum plants. Treatment with KNO3 concentration of 4 g/liter (E) and KNO3 concentration of 5 g/liter (F) had a better effect than other treatments on the growth and yield of potted chrysanthemum Cyra Agrohorti varieties

Zukini (Cucurbita pepo L.) belongs to the pumpkin tribe (Cucurbitaceae) including annual plants that live in the highlands. The need for zucchini in Indonesia is increasing along with the growing number of restaurants serving Japanese and Korean dishes. Information about the cultivation of zucchini in Indonesia is still limited, so that zucchini is rarely found among farmers. The purpose of the experiment was to get the right concentration of Bioboost fertilizer in order to give maximum zucchini yields. The experiment was conducted from February to April 2022 in Cihanjuang Rahayu Village, Parongpong, West Bandung Regency, West Java Province with an altitude of 1.243 m above sea level. The experiment menthod used complete randomized block design (CRBD) of five treatment and five replications. Each treatment consisted of 5 plants. so the total number was 125 plants. Treat the experiment A : 0 cc Bioboost/liter of water, B : 20 cc Bioboost/liter of water, C : 40 cc Bioboost/liter of water, D : 60 cc Bioboost/liter of water, E : 80 cc Bioboost/liter of water. The results showed that the concentration of Bioboost fertilizer was effective on the number of leaves, age of flower initiation, number of fruit/plant, fruit length/plant, fruit diameter/plant and fruit weight/plant.   The application of Bioboost with a concentration of 60 cc/liter of water had the best  effect on the growth and yield of the varieties Jacky Z-6 zucchini plant

Common bean (Phaseolus vulgaris L) is one type of vegetable crop favored by the Indonesian people. Its  cultivation requires specific planting medium and rich in nutriens to meet plant growth and development need. This study aims to obtain the best ratio of soil mass and chicken manure fertilizer which can increase common bean growth and yield . This experiment was conducted from April 2019 to June 2019, in Langensari Village, Lembang District, West Bandung Regency with an altitude of 1,200 m above sea level. The experiment used  Randomized Block Design (RBD)consisted of 5 treatments and repeated 5 times, namely  A = 4.0 kg of soil: 0.0 kg chicken manure , B = 2.0 kg of soil: 2.0 kg chicken manure , C =1,3 kg of soil  :2,7  kg chicken manure, D= 1,0 kg of soil : 3,0 kg chicken manure, and E = 2,7 kg of soil : 1,3 kg chiken manure per polibag.  Results showed that the use of planting media with a soil media mass ratio of  2,0 kg of soil : 2,0 kg chiken manure increase  plant height, number of leaves, number of fruits, fruit length and fruit weight compared the other treatmens, but the  flowering and fruiting age of the plants were not different beetwen  between treatments given.

Kedelai hitam adalah komoditas pangan kacang-kacangan yang mempunyai keunggulan untuk pembuatan kecap.  Pada penelitian ini diupayakan mencari beberapa genotif unggul dengan memberikan inovasi  bahan paket organik yang bervariasi guna meningkatkan pertumbuhan dan hasilnya serta efisiensi pupuk anorganik N P K. Percobaan dilakukan di Tanjungsari Kabupaten Sumedang. Rancangan yang digunakan yaitu Rancangan Petak Berbagi sebagai petak utama adalah paket inovasi bahan organik , anak petak adalah  genotipe kedelai hitam dan diulang  dua kali. Faktor pertama,  paket inovasi bahan organik terdiri dari empat taraf  100 % dosis N  P K rekomendasi,  75 % dosis N P K rekomendasi + Kompos Jerami, 50 % dosis N P K rekomendasi + Kompos Jerami + Pupuk Hayati dan  50 % dosis N P K rekomendasi + Kompos Jerami + Pupuk Hayati + Biochar. Faktor kedua, genotipe kedelai hitam terdiri atas lima taraf meliputi  Varietas Cikuray,  genotipe UNP 1,  genotipe UNP 2,  genotipe UNP 3 dan  genotipe UNP 4. Hasil percobaan menunjukkan terjadi interaksi antara beberapa genotipe kedelai hitam dengan paket inovasi bahan organik terhadap berat 100 butir biji. Hasil uji mandiri menunjukkan bahwa paket inovasi bahan oganik  memberikan pengaruh yang sama terhadap komponen pertumbuhan (tinggi tanaman danNisbah Pupus Akar ) dan hasil ( jumlah polong per tanaman, jumlah biji per tanaman, berat biji per tanaman, berat 100 butir biji), tetapi setiap genotipe menunjukkan hasil yang bervariasi dan hasil tertinggi ditunjukkan oleh paket inovasi bahan organik 50 % dosis N P K rekomendasi + Kompos jerami + Pupuk Hayati + Biochar dan  genotipe  UNP 1 .

Broccoli (Brassica oleracea var. italica) which is often called green flower cabbage is one type of vegetable that is popular with the public. To meet the growing needs of broccoli, its cultivation business requires the right planting medium and is rich in nutrients.This study aims to obtain a ratio of soil mass and granule organic fertilizer which can increase the growth and yield of broccoli. The experiment was carried out from March 2017 to May 2017, located in Cicalung Village, Wangunharja Village, Lembang District, West Bandung Regency, with an altitude of 1200 m above sea level. The design used was a randomized block design (RBD) with 7 treatments and repeated 4 times, namely A = 6 kg of soil: 0 kg of granular organic fertilizer, B = 5.9 kg of soil: 0.1 kg of granular organic fertilizer, C = 5, 8 kg soil: 0.2 kg granule organic fertilizer, D = 5.7 kg soil: 0.3 kg granule organic fertilizer, E = 5.6 kg soil: 0.4 kg granule organic fertilizer, F = 5.5 kg soil: 0.5 kg granule organic fertilizer, G = 5.4 kg soil: 0.6 kg granule organic fertilizer.The results showed that in treatment F the use  5.5 kg of soil: 0.5 kg of granular organic fertilizer gave a better effect on plant height, number of leaves, canopy width and gross weight but had the same effect on net weight between treatments give.
