Potassium Sources and Rates for Drip Irrigated Polyethylene Mulched Chilli Pepper

Fertigation with drip irrigation is one of the technologies to solve fertilization and irrigation problems in chilli pepper production using polyethylene mulch. Potassium (K) is one of the important macro nutrients that affect plant growth and development due to its roles in the biochemical and the biophysical processes in plants. The objective of this study was to determine the best sources and the optimum rates of potassium for drip irrigated polyethylene mulched chilli pepper field production. The study was conducted in January until July 2018 at Tajur Experimental Farm, Center for Tropical Horticulture Study, Bogor Agricultural University. The experimental design was a split plot with the K sources (KCl, ZK, NPK) as main plots and K rates that consisted of five levels (0, 68, 136, 204, 272 kg K2O. ha-1) as sub-plots. The results showed that the best optimum rate of K to produce fruit is 101.11 kg K2O.ha-1 with a maximum yield of 2.26 t.ha-1. Chilli crops fertilized with NPK and KCl had the greatest fruit weight per plant, fruit weight per plot, and fruit weight per hectare.

Induksi Mutasi Tanaman Leunca (Solanum nigrum L.) untuk Meningkatkan Keragaman Kandungan Tanin

Leunca (Solanum nigrum L. ) is one of the indigenous vegetables in Indonesia. The fruit of this vegetable is green and has bitter taste because of its tannin content. The objectives of this study were to get lethal dose 50 (LD50), diversity and to obtain candidates of mutant plants with high and low tannin content in young fruit and ripe fruit in leunca. The research was conducted at Pasir Kuda experimental station, Bogor; National Nuclear Energy Agency (BATAN), Jakarta; and postharvest laboratory of the Center for Tropical Horticulture Studies (PKHT IPB), Bogor, from December 2016 to July 2017. Leunca accession of SN 20 and SN 29 were irradiated using doses of 0, 100, 150, 200, and 250 Gy of gamma ray. The LD50 values for SN 20 and SN 29 were 171.944 Gy and 190.949 Gy, respectively. The analysis of tannin content was performed based on permanganate method by titration using potassium permanganate. The results showed that the highest tannin content of green stage fruit was found in SN20D3.5 with 200 Gy dose and the lowest was found in SN29D1.5 with 100 Gy dose. The highest tannin content of ripe fruit was found in SN20D4.6 with dose of 250 Gy and the lowest was found in SN20D3.1 with dose of 200 Gy. Recommended tannin content for leunca is the low tannin content.Keywords: diversity, gamma ray, indigenous vegetable, irradiation, LD50

The Use of Trellis and Mulch Increased Fruit Production of Spaghetti Squash (Cucurbita pepo L.)

Spaghetti squash is squash of American origin that has spaghetti-like characteristic of fruit flesh, unlike any other squash varieties. This study aims to investigate the use of trellis and mulch to increase the spaghetti squash production. The experiment was conducted at the Experimental Station of Centre of Tropical Horticulture, Bogor from April to November 2016. The experiment used a completely randomized block design with four replicates. Two factors were tested, i.e. the use of trellis and mulch as the main plots, and accessions of the spaghetti squash as a sub-plot. The treatments were the use of trellis and mulch, mulch without the trellis, the trellis without mulch, and without the trellis and mulch. The spaghetti squash accessions used in this experiment were accessions from Taiwan (F1) and from America. Each experimental unit consists of five plants with a total a total of 160 plants. The results of this experiment showed that the growing squash using mulch and trellis had the greatest number of fruits per plant, more marketable fruits and had the largest fruit weight as compared with the other treatments. Taiwan accession had more fruits per plant and total marketable fruits, the largest fruit weight, the longest and widest fruits with large fruit diameter. Taiwan accession produced fruits at lower nodes of the plants, and fruits can be harvested earlier than the American accession. Correlation analysis indicated that the more fruits per plant, the more number of fruits that are marketable, the greater fruit weight and more fruits can be harvested from the higher nodes of the plants. From agronomical point of view, Taiwan spaghetti squash would be preferable to obtain the high fruit production provided the crops were mulched and grown with trellis.Keywords: Cucurbitacea, trellis, mulch, plant culture

Seleksi Populasi Generasi Ke-2 (F2) Hasil Persilangan Pepaya Callina (IPB9) dan Carisya (IPB3)

Papaya (Carica papaya L.) is known as valuable fruit, because of it high nutrientcontent and economic value. Hybrid variety of papayaresultedfrom breeding program is still limited in Indonesia. The objective of this study is to describethe second generation of papaya population generated from crossing between Callina (IPB9) and Carisya (IPB3) to find a new genotype in the small size of fruit (500-700 g).

Kriteria Kemasakan Buah Pepaya (Carica papaya L.) IPB Callina dari Beberapa Umur Panen

<p>ABSTRACT</p><p><br />Papaya is one of the climacteric fruit that has a short shelf life. It has high potential as a source of vitamins and minerals. This research was aimed at studying the maturity criteria of postharvest ripeness of Callina papaya fruit of several picking ages and to determine the best picking ages for postharvest handling in order to extend the shelf life. Experiment was conducted in the Research Center for Tropical Horticulture, Bogor Agricultural University (PKHT, IPB) Papaya Farm Tajur, Bogor and postharvest ripening test was conducted at Postharvest Laboratory, Department of Agronomy and Horticulture, Bogor Agricultural University in February to July 2014. Experiment consisted of 4 treatments: 115, 120, 125 and 130 days after anthesis (DAA) with 3 replications. The longest shelf life for papaya Callina was obtained by fruit picked at 115 DAA (heat unit 2010.06 0C day) with the shelf life of 8 days. Picking ages 120 DAA (heat unit 2102.13 0C day) was the best picking ages for treatment to extend the shelf life because of the good chemical quality contained and its shelf life of 7 days. The older papaya fruits ripened faster than the younger papaya fruit. Younger papaya has a lower respiration rate than the older papaya. Picking ages did not affect the physical quality but affect the chemical quality of papaya fruit at the same postharvest maturity level.</p><p>Kata kunci: Callina, chemical quality, physical quality, shelf life</p><p> </p><p>ABSTRAK</p><p> </p><p>Pepaya merupakan salah satu buah klimakterik yang memiliki daya simpan pendek, tetapi memiliki potensi yang tinggi sebagai sumber vitamin dan mineral. Penelitian ini bertujuan untuk mempelajari kriteria kematangan pascapanen buah pepaya Callina dari beberapa umur panen dan menentukan saat panen terbaik untuk penanganan pascapanen dalam rangka memperpanjang masa simpan. Buah untuk percobaan diperoleh dari kebun pepaya Pusat Kajian Hortikultura Tropika, Institut Pertanian Bogor (PKHT, IPB) Tajur, Bogor dan pengujian kematangan pascapanen dilakukan di Laboratorium Pascapanen, Departemen Agronomi dan Hortikultura, Institut Pertanian Bogor pada bulan Februari - Juli 2014. Percobaan terdiri atas 4 perlakuan: 115, 120, 125 dan 130 hari setelah antesis (HSA) dengan 3 ulangan. Umur simpan terlama pepaya Callina diperoleh pada umur panen 115 HSA (satuan panas sebesar 2010.06 0C hari) dengan umur simpan 8 hari. Umur panen 120 HSA (satuan panas sebesar 2102.13 0C hari) merupakan umur panen terbaik untuk perlakuan memperpanjang umur simpan karena mutu kimia baik dengan umur simpan 7 hari. Buah pepaya yang dipanen tua lebih cepat masak dibandingkan dengan buah pepaya yang dipanen muda.
