Abstract

Fertilizer is the main source of nutrients for plants in relation to growth, development and production processes every day. Manure is a waste product from pets that can be used to improve soil fertility, soil biology and soil physical properties. This study aims to determine the effect of cow manure on the growth and production of lettuce plants (Lactuca sativa L.). The experimental design used was a single-factor complete randomized design (RAL), namely the dose of cow manure. There are 5 types of cow manure treatments, namely S0 (control), S1 (600 grams / polybag), S2 (700 grams / polybag), S3 (800 grams / polybag), S4 (900 grams / polybag). The analysis used is variety analysis (anova) based on observed variables. If there is a real effect, it is followed by the smallest real difference test (BNT) level of 5%. The results of variety analysis and average difference tests show that the use of cow manure with various treatments has a very real effect on plant height, leaf area, header weight, root weight and has a real influence on the number of leaves. The dose of cow manure 600 grams / polybag can increase plant height growth, leaf area and fresh weight of plants.

Abstract

Tanaman kedelai merupakan tanaman C3 yang dapat ditingkatkan pertumbuhannya melalui peningkatan CO2 internal dan pemberian bahan organik. Penelitian dilakukan untuk mengetahui pengaruh penyemprotan methanol dan pemberian jenis pupuk organik bokashi terhadap pertumbuhan tanaman kedelai. Penelitian dilaksanakan di Desa Poka Kecamatan Teluk Ambon, Kota Ambon. Penelitian berbentuk percobaan faktorial dalam Rancangan Acak Kelompok (RAK) dengan 3 kali ulangan. Faktor pertama adalam penyemprotan methanol yang terdiri atas dua taraf yaitu: tanpa penyemprotan methanol (kontrol) dan penyemprotan methanol. Faktor kedua adalah jenis pupuk organik bokashi yang terdiri atas tiga taraf yaitu: tanpa pemberian bokashi (kontrol), pemberian bokashi pupuk kandang ayam, pemberian bokashi tekelan/kirinyuh. Hasil penelitian didapatkan informasi bahwa faktor tunggal pemberian methanol dan bokashi memberikan pengaruh yang signifikan terhadap semua peubah pengamatan, sedangkan interaksi antara kedua perlakuan tidak memberikan pengaruh yang signifikan. Faktor tunggal penyemprotan methanol memberikan hasil yang tertinggi terhadap semua peubah pengamatan, sedangkan faktor tunggal bokashi tekelan/kirinyuh memberikan hasil yang tertinggi terhadap semua peubah pengamatan.

Abstract

spell analysis is one of the indicators that can be used to measure the level of vulnerability of a region to drought. This study aims to determine the chances of a series of dry days during the effective growing season during El-Nino on Ambon Island. Data analysis was carried out with the following stages: (1) calculating rainfall probability 75% using the ranking order method, and potential evapotranspiration using the Penman-Monteith method in the Cropwat 8.0 Program package, (2) calculating land water balance and determining the effective growing season based on optimum soil water content, (3) determining the years of El Nino occurrence and the chances of a series of dry days. The results of the study showed that the effective growing season on Ambon Island lasted for 7 months; April to October. The El Nino event on Ambon Island during the period 1979 – 2023 tends to occur once every three years. The chances of a series of dry days ≥ 5 days during the growing season ranged from 56 - 88%; ≥ 10 days: 27 - 88%; ≥ 15 days: 7 - 80%; and ≥ 20 days: 0 - 47%.

Abstract

This research was conducted in Pelita Jaya Village, Pohon Batu Hamlet, West Seram Regency from June to July 2022. The research was conducted to study the effect of the interaction of doses of organic fertilizer from pearl oyster biofouling waste and intervals of water administration on the growth and yield of mustard plants. The design used in this study was a factorial randomized group trial design (RAK) with two treatments as follows: Factor I: Pearl Oyster Biofouling Waste Fertilizer (L) with 4 levels, namely L0 = Control, L1 = Dosage of 50 gr/tan, L = 100 g/tan and L3 = 150 gr/tan Factor II : Watering Time Interval (W) namely W1 = 1 day, W2 = 2 days and W3 = 3 days. Each treatment was combined to obtain 12 treatments with 3 replications, resulting in 36 experimental plots. In each plot, 4 sample plants were taken so that in total there were 144 sample plants. The results of this study indicate that the interaction of organic fertilizer from pearl oyster biofouling waste with intervals of watering has a very significant effect on the growth and yield of mustard plants (number of leaves, leaf area, plant fresh weight and plant dry weight). The best treatment interaction was the combined dose of pearl oyster biofouling waste fertilizer 150 g/tan with an interval of watering once every three days for mustard greens (Brassica juncea L.)
