Abstract

ABSTRACTShallot is one of important commodity besides chili and potatoes. Shallot is cultivated on dry land. The dry land used in Indonesia is still relatively small, while the potential of this area is considered large for the development of agriculture. Pressurized irrigation system has the advantage of efficient use of water making it suitable to be applied on dry land. The study consisted of two experiments, the effect of irrigation volume and frequency of irrigation influence on the growth of shallot. The research was conducted at the Experimental Station Teaching Farm and Postharvest Laboratory Department of Agronomy and Horticulture, Bogor Agricultural University from October 2014 to April 2015. The research consisted of two experiments by using a Randomized Block Design with four replications. The treatment in the first experiment was percentage of the volume of irrigation water consisting of five levels (S100% ETc, S75% ETc, S50% ETc, S25% ETc (with sprinkler) and 100% ETc conventional (without sprinkler). The treatment in the second experiment was frequency of irrigation consisting of four levels (two times a day, once a day, once in two days one and once in three days). Results of the first experiment showed the plants could growand produced up to S25% ETc or 81.17% water available for evapotranspiration, but the best treatment was S100% ETc volume irrigation, based on yields. Watering with sprinkler irrigation provided better effect than manual watering which was usually done by farmers. The second eperiment showed that the best watering frequency for vegetative growth was once a day while for total yield was twice a day.Key words: dryland, irrigation, shallot, sprinkler, total yield, vegetative growth,ABSTRAKBawang merah salah satu komoditas unggulan nasional selain cabai dan kentang.

Abstract

ABSTRAKPemberian larutan KNO3 diduga dapat meningkatkan produktivitas tanaman iles-iles (Amorphophallus muelleriBlume). Penelitian bertujuan mempelajari pengaruh pemberian larutan KNO terhadap produktivitas A. muelleri. Umbiutuh umur satu tahun dengan bobot 100-125 g ditanam dalam polibag yang ditempatkan di bawah naungan paranet 50%pada musim hujan (September 2010-April 2011) di Bogor, Indonesia. Lima taraf larutan KNO3 yaitu 0, 2, 4, 6 dan 8% (b/v)diberikan melalui daun dan melalui tanah. Larutan diberikan 2 kali sebulan mulai 12 minggu setelah tanam (MST). Hasilmenunjukkan bahwa pemberian KNO3-13 nyata mempengaruhi pertumbuhan tanaman, khususnya meningkatkan jumlah daundan memperpanjang masa vegetatif. Pemberian KNO pada taraf 4% memberikan pengaruh tertinggi jika diberikan melaluidaun. Pemberian KNO33 taraf 4% memberikan pertumbuhan yang lebih tinggi jika diberikan melalui daun dibandingkanmelalui tanah. Secara umum, tidak ada pengaruh nyata pada pertumbuhan tanaman akibat pemberian dosis KNO yangdiberikan melalui tanah. Penelitian berimplikasi bahwa pemberian pupuk KNO melalui daun pada taraf 4% dapatditingkatkan efektivitasnya jika kerusakan pada anak daun dapat diminimalkan. Kerusakan daun cenderung meningkat padadaun tua, oleh karena itu, studi lanjut perlu dilakukan terkait waktu aplikasi yang tepat.Kata kunci: iles-iles, kalium nitrat, pupuk daun, pertumbuhan vegetatif

Abstract

Tomato (Lycopersicon esculentum L.) was grown with polyethylene mulch and drip irrigation on a Millhopper fine sandy soil testing very high in P and low in organic matter during two seasons to evaluate the effect of S source, rate, and application methods on plant growth and yield of fruit.  Sulfur rate of 34 and 68 kg S.ha-1 were applied with  preplant (broadcast in the bed), drip (10 weekly drip application), and  by split applications (50% preplant and 50% drip).  In split applications, S sources evaluated were ammonium sulfate and ammonium thiosulfate.  Plant height was increased with S application from 0 to 68 kg S.ha-1 in both studies. However, response on plant dry weight only occurred in spring 1999. Total marketable yield was 17.9 tons.ha-1 with 0 kg S.ha-1 and was increased linearly to 48.1 tons.ha-1 with application of 68 kg S.ha-1 in Spring 1999, but no response to S was obtained in the Spring 1998 study. Measured variables were not affected by S source and methods of application.  Increasing S application from 0  to 68 kg S.ha-1 reduced leaf and plant tissue P concentration 14 and 12% at mid season, 26 and 25% at  late season sampling times, respectively.  S application of 68 kg S.ha-1 reduced soil pH approximately 0.3 unit at the end of the season in both studies.   Key  words:  drip irrigation, sulfur,  fertigation, Lycopersicon esculentum

Abstract

Chili peper (Capsicum annuum L.) var. Prabu was grown with polyethylene mulched and drip irrigation system on Andosol Sukamantri soil with low pH (4.5), low C-Organic (1.79%), low N-total (0.18%), high K content (0.76 me/100 g), and very high soil P2O5 concentration (190 ppm) to optimise fertilizer rate for drip irrigated and polyethylene mulched crop management system. This research was conducted from March - July 2004 at Danasworo Hydrogarden Ciapus Bogor. This research was arranged in Randomized Completely Block Design with four levels of fertilizer rate (0=control; 1x recommendation rate =151 kg N/ha, 69 kg P2O5/ha, 120 kg K2O/ha; 2x recommendation rate = 302 kg N/ha, 138 kg P2O5/ha, 240 kg K2O/ha; 3x recommendation rate = 453 kg N/ha, 207 kg P2O5/ha, 360 kg K2O/ha). Hundred percent of P, 50% N and K were applied pre-plant and 50% N and K were fertigated 10 times. The result showed that plant height and plant dry weight increased linearly with fertilizer application from 0 to 3x recommendation rate. Total marketable yield was quadratically increased with fertilizer application from 0 to 3x recommendation rate. Base on total marketable yield, optimum recommendation rate for chili with drip and polyethylene mulch were 237.07 Kg N/ha, 108.33 Kg P2O5/ha, and 188.4 Kg K2O/ha.   Key words :  Chili, fertilizer, drip irrigation, polyethylene mulch, fertigation
