ABSTRACTThis research was conducted in the Analitic laboratory of Palangka Raya Univercity and in the screenhouse of Agriculture Cultivation Department, Palangka Raya Univercity. The purpose of thisexperiment was to determine the effect of dolomit and chicken manure to some soil chemicalproperties of acid sulfate soil and growth of Maize Crop (Zea mays L.). The research was arranged inComplete Ramdomized Design with two factors and three replications. The first factors were level ofdolomit with three levels namely 0 ; 1,5 ; 3,0 times exchangeable alumunium. The second factors werelevel of chicken manure with three levels namely 0, 6 and 12 t ha-1. The results showed that theinteraction between dolomit and chicken manure significantly affected increasing the soil pH anddecreasing exchangeable alumunium. The combination level of dolomit in level 1,5 timesexchangeable alumunium with application of 6 ton.ha-1 chicken manure will be optimum increasingthe soil pH and decreasing exchangeable alumunium. The application a single factor of dolomit notsignificantly affected P-availabilityand growth of Zea mays (plant height, number of leaf and area leafindex) in age 2, 3, 4, 5, 6 weeks after planting. The application of chicken manure only significantlyaffected increasing P- availabilityand growth of Zea mays (plant height, number of leaf and area leafindex) in age 2, 3, 4, 5, 6 weeks after planting. Optimum dosage of chicken manure was 6 t ha-1.Keywords: sulfate soil, dolomite, soil chemical, chicken manures.

Seed produced on three widely grown public corn (Zea mays L.) inbreds were tested for tolerance to drying injury. Inbred parents A632, B73, and Mo17 were grown in 1979 and 1980. The single cross H99 × H95 was used as a pollinator both years. Random ear samples were collected, to obtain ears with moisture percentages ranging from approximately 50 to 20%, and dried to 12% moisture at 35 °C, 40 °C, 45 °C, and 50 °C. Inbred parents were found to differ in tolerance to high drying temperatures. A632 was the most tolerant to high drying temperatures whereas B73 and Mo17 were relatively intolerant. Field performance of dried seed was similar to that observed in laboratory tests. Combined analyses yielded significant inbred-parent by harvest-moisture by drying-temperature interactions for germination and cold-test emergence percentages. These interactions do not allow for simple recommendations of safe harvest moistures and drying temperatures. Components from the combined analysis that had a P > F of 0.30 or less were then used to predict mean values for A632, B73, and Mo17 germination, cold-test emergence, seedling dry weight and the ratio of shoot to root dry weight. Values for the ratio variable indicated that root development is more susceptible to injury than is shoot development. These predicted values provide seed producers with information on the quality responses that they could expect when seed of A632, B73, or Mo17 is harvested at different moisture contents and dried at different drying temperatures.Key words: Drying, seed quality, Zea mays L.

This study was aimed to determine the proper dose of ash desiccant on maize seed stored for 30, 60 and 90 days. The design used was a Completely Randomized Factorial Design, with two factors and three replications.  The first factor was desiccant dose (D) : Do = 0 % (control), D1 = 5 % (12.5 g of seed weight), D2 = 10% (25 g of seed weight), D3 = 15 % (37 g of seed weight), D4 = 20 % (50 %g of seed weight), D5 = 25 % (62.5 g of seed weight).  The second factor was length of storage (S) : S1 = 30 day storage, S2 = 60 day storage and S3 = 90 day storage. The result show that use of desiccant only gave effect on the water content of seeds (12.31 %) and speed of seed growth vigor parameters (24.84 %).  Use of desiccant in 90 day storage were able to maintain water content of seeds (12.43 %), seed germination viability parameter (100 %), and vigor of seeds, which consisted of seed growth simultaneity (66.77 %) and seed growth speed (28.71 %).  The interaction between the use off ash desiccant and the length of storage had no effect on  viability and vigor of maize (Zea mays L) seeds but had an effect on their water content after storage (12.73%).

The study, entitled the effect of the administration of Palm Oil Long Palm (AJKS) to the growth and production of two corn varieties inpeatlands, was carried out from October 2017 to March 2018 in trench 3 in Tembilahan Hulu Village, Tembilahan Hulu District, Indragiri Hilir Regency,soil analysis and AJKS conducted at the Bogor Institute of Agriculture Laboratory. The purpose of this study was to determine the effect of AJKSadministration on the growth and production of two maize varieties (Zea mays L) on peatlands, and to determine whether there was an interactionbetween the dosage of AJKS and corn varieties on peat soil ameliorating AJKS. The design used was factorial Randomized Block Design (RBD) using 2factors with three replications. The first factor is the dose of AJKS administration consisting of 4 levels, namely: A0: 0 kg / ha, A1: 500 kg / ha, A2: 1000kg / ha, A3: 1500 kg / ha. The second factor is corn varieties with 2 levels, namely: V1: Pioneer Varieties and V2: Varieties N35. Of the two factors aboveobtained 8 treatment combinations. Based on the results of research that has been done, that there is no real interaction and influence between thetreatment of giving AJKS with varieties to all observed parameters. Giving AJKS 1500 kg / ha gives the highest yields on all parameters observed exceptfor the number of cobs, Pioneer variety is the variety that responds most to AJKS administration.

Since corn is grown in climatically diverse regions and under different production conditions, assuming that high salinity in the substrate affect corn seed performance, such conditions were simulated in this study in order to examine their effects on seedling geminability and length in several corn genotypes. The study showed that the tested seeds tolerated the stress conditions up to a certain point. The studied genotypes differed in level of resistance to the stress conditions. Salt concentrations were determined, which were capable of affecting negatively seed germinability and seedling growth.

Sari Penelitian ini bertujuan untuk mengetahui pengaruh interaksi dan kombinasi yang terbaik antara pemberian dosis pupuk hayati dan dosis pupuk N, P, K terhadap pertumbuhan dan hasil tanaman jagung hibrida P-12. Percobaan dilakukan di Kebun Percobaan Fakultas Pertanian Universitas Padjadjaran Jatinangor, dengan ketinggian 760 meter di atas permukaan laut, jenis tanah inseptisol dan tipe iklim C3 menurut Oldeman. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK) pola faktorial dengan dua faktor perlakuan. Faktor pertama adalah dosis pupuk N, P, K yang terdiri dari tiga taraf yaitu k1 = 100% pupuk N, P, K, k2 = 75% pupuk N, P, K dan k3 = 50% pupuk N,P, K. Faktor kedua adalah dosis pupuk hayati Petrobio (H) yang terdiri dari tiga taraf, yaitu h1 = 60 kg/ha pupuk hayati Petrobio, h2 = 90 kg/ha pupuk hayati Petrobio, dan h3 = 120 kg/ha pupuk hayati Petrobio. Masing – masing kombinasi perlakuan diulang sebanyak tiga kali. Hasil penelitian menunjukkan bahwa tidak terdapat interaksi antara dosis pupuk hayati dan pupuk N, P, K terhadap setiap parameter pengamatan komponen hasil dan hasil tanaman jagung hibrida P-12 di dataran medium Jatinangor.
