Abstract

Corn yield improved by genetic improving, plant population and fertilizer. The experiment aims to knowing the effect off row circle planting method and hybrid corn variety toward population and yield of corn. The experiment was conducted on August- November 2015 in Siman, Ponorogo, altitude 140 amsl and textured clay grumosol soil types. The experiment was a factorial experiment in a complete block randomized design with two factor and three replications. The first factor was hybrid corn varieties (Bisi-18, NK-7328, Pertiwi-3, and Pioneer-27). The second factor was row circle planting method (single manner with interval planting of 60x40x20 cm; row circle planting method with interval planting of 60x100 cm and 100x50x50 cm). The result showed not significantly interaction between row circle planting method and hybrid corn varieties with respect to population total and corn yield. Row circle planting method with interval planting 100x50x50 cm increased plant population about 164.413 plants/ha and significantly different with single manner with interval planting of 60x40x20 cm (62,881 plants/ha) and row circle planting method with interval planting 60x100 cm (136,774 plants/ha). Hybrid corn varieties was not significantly increased plant population. Pioneer-27 variety of hybrid corn produced weight of wet corn logs by 17,22 ton/Ha and significantly different with Bisi-18, NK-7328 and Pertiwi-3. Hybrid corn varieties was not significantly affects to increasing produce of dry corn kernels. Variety of Pioneer-27 produced dry corn kernels 7,28 ton/ha and was not significantly different with varieties of Bisi-18, NK-7328, and Pertiwi-3. Variety of NK-7328 had percentage weight of wet corn logs into dry corn kernels as big as 55,38% bigger than varieties of Bisi-18, Pertiwi-3 and Pioneer-27.

Abstract

Azolla microphylla is one of the green resources fertilizer, adding natural P respectively will increase the biomass including. The on time embedding of azolla are able to provide nutrition to the plants such as rice especially N. The experiment was conducted in Desember 2nd , 2006 - April 5th , 2007 in Tegalgondo, Karangploso, Malang, East Java ( 550 m up sea level). The experiment applied Randomized Block Design (RBD) under two factors, dose and embedding time with three replications. The doses were applied are P0 = 0 kg ha-1; P1 = 25 kg P ha-1; P2 = 50 kg P ha-1; and P3 = 75 kg P ha-1 . The embedding times were a day before planting, 50 % azolla in 14, 28 and 24 days after planting, 50 % azolla in 21 and 49 days after planting, and 50 % azolla in 35 day after planting. The parameters of observation were wet weigh of azolla; N, P , K contents before and after treatments and azolla decompositions. The result showed 75 kg P ha-1 with interaction of azolla embedding, was the most effective dose to increased azolla biomass.

Abstract

The effort of growing azolla in intercroping rice will be hoped to supply a green manure for rice plants. Additing P of the phosphat rock in the field can be expected to increase the result of rice yield.The research was conducted on December 2, 2006 to April 5, 2007 at Tegalgondo Karangploso of Malang. onsidering those problems, the researcher employs the factorial group randome desigh that compose two factor by controlling as comparison tool (inorganic treatment). The first factor is P in the phosphat rock contained 4 stages. As followed Po (without P), P1 (25 kg P ha-1), P2 (50 kg P ha-1), P3 (25 kg P ha-1). The second factor is time of incorporated Azolla microphylla Kaulfuss (W), which consist 4 stage. As followed W1 (incorporated 1 day before transplanting rice), W2 (50 % the azolla biomass in the field was incorporated during 14, 28, and 42 days after transplanting rice), W3 (50 % the azolla biomass in the field was incorporated during 21, and 49 days after transplanting rice), W4 (50 % the azolla biomass in the field was incorporated during 35 days after transplanting rice). The research was replicated 3 replications. The research finding showed that phosphat rock with 25 kg of P ha-1 doses combinationed with time of incorporating the azolla biomass at 14, 28 and 42 days after transplanting rice, the result of rice would be increasing in 31,4 % and R/C value resulted 1,47. Giving phosphat rock with 25 – 75 kg P ha-1 doses increased the azolla biomass at 146,4 % until 153 % and increased the yield of rice at 21,1% until 43,8 %.

Abstract

Kemampuan ekstrak daun selasih dan pandan wangi dalam menarik kedatangan lalat buah dipengaruhi oleh kandungan bahan aktif seperti Metil Eugenol (ME) (C12H14O2). Rendeman minyak hasil perebusan daun selasih adalah 1,14% dengan kadar ME mencapai 76%. Sedangkan kadar kandungan ME dalam minyak atsiri daun pandan wangi sekitar kadar 5%. Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak selasih dan pandan wangi terhadap lalat buah. Penelitian dilakukan pada buan Agustus 2019 di Kecamatan Mlarak dan Sawo, Ponorogo, Jawa Timur. Terdapat dua perlakuan yaitu ekstrak daun selasih dan daun pandan yang masing-masing diulang tiga kali. Pengambilan sampel lalat buah didapatkan dari pemasangan perangkap di delapan petak lahan. Sedangkan, pengambilan sampel buah rusak diambil dari tanaman cabai rawit. Hasil penelitian ini menunjukan bahwa ekstrak daun pandan wangi dan daun selasih mampu menarik lalat buah. Namun, ekstrak daun kemangi lebih efektif dibandingkan dengan daun pandan. Jumlah  lalat buah yang tertangkap pada perlakuan ekstrak daun selasih di daerah Mlarak 116 ekor dan Sawo 83 ekor, lebih banyak dibandingkan dengan ekstrak daun pandan wangi  yang berjumlah masing-masing 11 ekor di kedua lahan peneltian. Kemudian, intensitas serangan pada buah cabai paling banyak pada lahan dengan perlakuan ekstrak daun pandan mencapai 33.74% di Mlarak dan 29.61% di Sawo. Sedangkan spesies lalat buah yang tertangkap ialah betina dari B. carambolea, B. umbrosa, dan B. fuscitibia.

Abstract

The research aims to determine the effect of a combination of inorganic fertilizer (KNO3) and organic fertilizer (goat manure) on the yield of the Betavila variety when apical shoots are pruned. The research took place from March to October 2019 in Kupang Regency, NTT. The research used RAK with 4 repetitions. The treatments are as follows: M1 = inorganic fertilizer 5 g/l KNO3; M2 = organic fertilizer 20 tons/ha goat manure; M3 = inorganic fertilizer 5 g/l KNO3 + organic fertilizer 30 tons/ha goat manure; M4 = inorganic fertilizer 5 g/l KNO3 + organic fertilizer 15 tons/ha goat manure; M5 = Inorganic fertilizer 3.75 g/l KNO3 + organic fertilizer 15 tons/ha goat manure; M6 = Inorganic fertilizer 3.75 g/l KNO3 + organic fertilizer 30 tons/ha goat manure; M7 = inorganic fertilizer 2.5 g/l KNO3 + organic fertilizer 15 tons/ha goat manure; M8 = inorganic fertilizer 2.5 g/l KNO3 + organic fertilizer 30 tons/ha goat manure. The results of the research showed that the combination of applying inorganic fertilizer and organic fertilizer simultaneously influenced the yield of Betavila variety tomato plants whose apical shoots had been pruned, namely on the number of fruits, fruit weight, and fruit production. Fertilization dose of inorganic fertilizer 3.75 g/l KN03 + organic fertilizer 30 tons/ha goat manure gave the number of fruits per plant (59.63 fruit), fruit production per plant (2.63 kg), and fruit production per experimental plot (50.33 kg) highest.

Abstract

Shallot plants (Allium ascalonicum L.) have short roots and soft leaves, potentially susceptible to environmental stress and pest attacks. Fulfillment of nutrients and variety selection as an alternative in increasing shallot production. The research aims to determine the effect of liquid organic fertilizer (LOF) modified silica (Si) and varieties on the productivity of shallot plants. The research was carried out at the Universitas Darussalam Gontor experimental field from November 2023 to January 2024. The research used a split-plot design with 2 factors. First factor: POC modified Si, P1 = POC 5 ml + Si 5 g.l-1, P2 = POC 10 ml + Si 5 g.l-1, P3 = without fertilizer (control). Second factor: variety, V1 = Bima Brebes, V2 = Thailand. Observation parameters were plant height, number of leaves, number of tillers, tuber diameter, wet and dry weight of tubers per plot (1 m-2), and wet and dry weight of the entire plant per plot (1 m-2). The observation data were analyzed using ANOVA and then tested further with 5% BNT. POC 5 ml + Silica 5 g.l-1 treatment increased the number of leaves, tillers, and wet and dry weight of shallot bulbs. The Bima Brebes variety has better plant height and diameter than the Thailand variety which is significantly different, while the number of tillers for the Thailand variety is greater. The Bima Brebes variety fertilized with POC 5 ml + Silica 5 g.l-1 increased the entire shallot plant's wet and dry weight (total bulbs and leaves).
