Penelitian ini bertujuan untuk mengetahui pengaruh pupuk pelengkap cair terhadap pertumbuhan dan hasil beberapa genotip krisan hasil poliploid. Penelitian ini dilaksanakan di rumah kaca Fakultas Pertanian Universitas Winaya Mukti, dari bulan Juni sampai dengan bulan September 2018 dengan ketinggian tempat 878 meter di atas permukaan laut(m dpl). Rancangan percobaan yang digunakan adalah Rancangan Petak Terbagi (Split Plot Design)yang terdiri dari 2 faktor dan 2 ulangan. Faktor pertama adalah konsentrasi PPC (P) ditempatkan sebagai petak utama yang terdiri dari 5 taraf yaitu : p0 = Tanpa PPC, p1 = PPC 1 ml L-1 larutan, p2 = PPC 2 ml L-1 larutan, p3 = PPC 3 ml L-1 larutan, p4 = PPC 4 ml L-1 larutan. Faktor kedua adalah genotip krisan hasil poliploidi (G) ditempatkan sebagai anak petak yang terdiri atas 4 taraf yaitu : g0 = KRA0, g1 = KRA1, g2 = KRA2, dan g3 = KRA3. Hasil percobaan ini menunjukan bahwa terjadi interaksi antara konsentrasi pupuk pelengkap cair dan genotip krisan KRA0,KRA1,KRA2,KRA3 pada tinggi tanaman umur 12 MST, diameter batang umur 2 MST. Pengaruh konsentrasi pupuk pelengkap cair pada genotip krisan hasil poliploidi menunjukkan pengaruh yang lebih baik terhadap tinggi tanaman pada umur 12 MST, diameter batang 2 MST, 10 MST, dan 12 MST, jumlah daun per tanaman pada umur 10 MST dan 12 MST. Berdasarkan hasil percobaan dan analisis ditemukan bahwa PPC 3 ml L-1 berpengaruh terhadap genotip krisan hasil poliploidi KRA1 yang memberikan pertumbuhan genotip krisan hasil poliploidi terbaik.

Perubahan iklim global dan kerusakan lingkungan telah mengakibatkan perluasan lahan pertanian khususnya persawahan yang telah tergenang air. Kondisi tersebut menyebabkan produksi beras di lumbung padi menurun. Penggunaan varietas tahan perendaman merupakan salah satu solusi untuk mengatasi pertanaman padi yang dilanda banjir, salah satunya pemanfaatan padi lokal, karena padi lokal memiliki keunggulan seperti batang tinggi, tahan penyakit, dan tahan terhadap cekaman lingkungan termasuk cekaman rendaman. Penelitian ini bertujuan untuk meningkatkan produksi padi di daerah rawan banjir melalui pendugaan nilai keragaman dan heritabilitas karakter penting beberapa pembudidaya padi lokal akibat cekaman perendaman yang berbeda. Terdapat keragaman genotipe yang luas yaitu karakter bobot 1000 biji dengan standar deviasi 2,10> 1,84 dan ada keragaman fenotipik yang luas untuk karakter bobot 1000 biji (2,10> 1,84). Sedangkan nilai estimasi heritabilitas adalah nilai karakter tinggi untuk karakter vigor benih (0,72), tinggi tanaman 80 HST (0,53), umur tanaman saat panen (0,56), dan bobot 1000 biji (0,90)) dan terdapat nilai estimasi heritabilitas sedang pada karakteristik tinggi tanaman 40 HST (0,39) dan umur panen (0,33).

ABSTRACTThis study aimed to: (1) study the effect of interactions between gibberellin concentration and several wetland rice varieties on conditions of high salinity stress on growth and yield, (2) gibberellin concentration and lowland rice varieties which have the best influence on growth and the results of lowland rice. The research was carried out at the screen house of the Faculty of Agriculture, Winaya Mukti Tanjungsari University - Sumedang Regency with altitude 850 m above sea level. The time of the study was carried out in December 2014 until April 2015. The study used a factorial Randomized Block Design method, which consisted of two factors: gibberellin concentration and several varieties of lowland rice in high salinity stress. The first factor is the concentration of gibberellin (G), consisting of four levels: g0 = soaking the seeds for 24 hours in giberelin 0 mgL-1 = soaking the seeds for 24 hours in gibberellins 20 mgL-1, g2 = soaking the seeds during 24 hours in gibberellins 40 mgL-1, g3 = soaking the seeds for 24 hours in giberelin 60 mgL-1. The second factor is rice paddy variety (P), consisting of eight levels: p1 = Inpari 10, p2 = Inpari 20, p3 = Inpari 25, p4 = Inpari 26, p5 = Inpari 27, p6 = Inpari 30, p7 = Inpara 4, and p8 = Banyuasin. The results of the study indicate that here is an interaction effect between gibberellin concentrations and some lowland rice varieties in high salinity tresses against root drop ratio at ages 7, 35 and 49 HST. Rice varieties independently affect the age of harvest and the weight of 1000 seeds. There is a concentration of gibberellins and lowland rice varieties that produce the best growth and yield in high salinity stress.

An experiment was carried out from May to October 2015 at Experimental Field of Agriculture Faculty Winaya Mukti University Tanjungsari Campus, at the altitude of 850 m above sea level, Inceptisols soil order. The objective of these experiment was to study interaction effect of Chicken manure and Phonska Rates on Yield of Sweet Potato Cilembu Variety. Experimental design used was a Randomized Block Design (RBD) in factorial pattern with 2 replications. The fisrt factor named chicken manure rates (A), contain of 4 levels, named : a0 = without chicken manure, a1 = 10 t ha-1, a2 = 20 t ha-1, a3 = 30 t ha-1. Rates of Phonska (P) contain 4 levels, named : p0 = without Phonska, p1 = 400 kg ha-1, p2 = 800 kg ha-1 p3 = 1.200 kg ha-1. Result of experiment showed that interaction between chicken manure and phonska rates was not significant on yield of sweet potato Cilembu variety. Main effect of chicken manure rates and phonska rates were significant on plant dry weigt at one, two, three and four month after planting, weight of first class tuber and total tuber plot-1, while the effect on number of tuber is not significant. The optimum chicken manure rate was 28,87 ton ha-1 with maksimum first class yield 17,96 t ha-1, and optimum chicken manure rate was 27,18 t ha-1 with total tuber yield 20,51 t ha-1. Tuber yield response toward phonska rates was linear.

Abstract Pakcoy is a popular vegetable, besides being easy to cultivate, it also contains many benefits. In 2017-2019 Pakcoy production decreased. This is caused by several factors, one of which is the use of planting media and fertilization. The purpose of this experiment was to determine the interaction between the composition of the growing media and the concentration of complementary fertilizers on the growth and yield of pakcoy plants. This experiment was carried out in Sindanglaya Village, Tanjungsiang Disrtict, Subang Regency with an altitude of 700 meters above sea level an average daily temperature of 27.27ºC. The experiment was carried out in July-August 2020. The design used was a factorial randomized block design (RBD) consisting of two factors and repeated twice. The first factor is the composition of the planting medium (M) which consists of four levels, namely: m0 = (soil), m1 = (soil + sheep manure), m2 = (soil + cow manure), m3 = (soil + manure ) chicken). The second factor is the concentration concentration of bayfolan liquid complementary fertilizer (P) which consists of four levels, namely: p1 = (1 ml L-1), p2 = (2 ml L-1), p3 = (3 ml L-1), p4 = (4 ml L-1). The experimental results showed the interaction of planting media and bayfolan liquid complementary fertilizers on wet weight. Soil planting medium + chicken manure (m3) and liquid complementary fertilizer 2 ml L-1 (p2) showed the best results, namely 1.07 kg.
