Abstract

The purpose of this study was to investigate smart k – sprinkle fertigation in dry land with potassium nutrition supply on growth and yield of shallot plants. The study was conducted in the Research Field Department of Agroecotechnology, Faculty of Agriculture, University of Sultan Ageng Tirtayasa, Indonesia from August to November 2020. The experiment was designed in a Randomized Complete Block Design (RCBD) with four replications. Experiment was conductedin six different treatments as K50: Potassium nutrition of 50 kg.ha-1 under smart K – sprinkle fertigation system; K75: Potassium nutrition of 50 kg.ha-1 under smart K – sprinkle fertigation system; K100: Potassium nutrition of 50 kg.ha-1 under smart K – sprinkle fertigation system; K125: Potassium nutrition of 50 kg.ha-1 under smart K – sprinkle fertigation system; K150: Potassium nutrition of 50 kg.ha-1 under smart K – sprinkle fertigation system; Control: conventional fertilizer of 100 kg.ha-1 as basal dose recommendation. The results showed thatsmart K – sprinkle fertigation system revealed to increase shallot plant on growth and yield. Besides, the use of Potassium nutrition of 50 kg.ha-1 (K50 treatment) showed the highest value on number of leaves plant weight, and bulbs weight per plant, as well as on the potential yields. So that, further study is recommend to observe the application of smart K – sprinkle fertigationsystem in combination with other nutrition.Keywords: potassium, fertilizer, micro sprinkle, onion

Abstract

AbstrakBudidaya bawang merah (Allium cepa L.) di Provinsi Banten terhambat oleh masalah kekurangan air karena diusahakan di lahan kering. Oleh karena hal tersebut, kami mengevaluasi pengaruh pemberian kalium klorida (KCl) melalui fertigasi tetes untuk efisiensi penggunaan air dan nutrisi pada budidaya bawang merah di lahan kering Banten. Penelitian polybag dilaksanakan dengan rancangan acak kelompok lengkap (RAKL) dengan 4 ulangan sebagai blok. Perlakuan terdiri dari dosis KCl dengan system fertigasi tetes yakni 50, 75, 100, 125 dan 150% dari dosis rekomendasi KCl untuk Provinsi Banten dan aplikasi KCl dengan sistem irigasi konvensional sesuai dosis rekomendasi sebagai kontrol. Hasil penelitian menunjukkan bahwa tinggi tanaman bervariasi pada berbagai perlakuan pada pengamatan 6 dan 8 minggu setelah tanam (mst). Tinggi tanaman maksimal mencapai 49,4 cm pada perlakuan fertigasi tetes dengan dosis KCl 75% pada umur 6 mst dan 43,5 cm pada umur 8 mst. Jumlah daun pada umur 6 mst juga menunjukkan adanya variasi pada berbagai perlakuan. Jumlah daun terbanyak mencapai 23,1 helai yang ditunjukkan pada perlakuan fertigasi tetes dengan dosis KCl 75%. Namun, pada pengamatan kehijauan daun tidak menunjukkan beda nyata antar perlakuan. Hasil panen menunjukkan bahwa perlakauan fertigasi tetes pada dosis KCl 75% menunjukkan jumlah umbi per tanaman paling banyak (9,3 umbi per tanaman) dan bobot tumbi tertinggi (38,95 gram per tanaman). Dari hal tersebut menunjukkan bahwa aplikasi fertigasi tetes dapat mengurangi 25% dosis rekomendasi KCl dibandingkan dengan sistem konvensional.Kata Kunci: KCl, dosis, sistem irigasi, umbi, penelitian polibag AbstractShallot (Allium cepa L.) cropping in the Province of Banten has been impeded by water deficit problem due to it is occupying dry land areas. Therefore, we evaluated the effect of different potassium chloride doses under drip fertigation to increase the growth and yield of shallot in the dry land area of Banten. Potted research was laid out in a Randomized Completely Block Design (RCBD) with four replications as blocks. The treatment consisted of 50, 75, 100, 125, and 150% basal dose recommendation of potassium chloride under a drip fertigation system and 100% basal dose recommendation of potassium chloride under a conventional irrigation system as a control. The result revealed that plant height varied significantly due to the various level of potassium chloride at 6 and 8 weeks after planting (wap). Plant height was maximum at 75% basal dose recommendation of potassium chloride using drip fertigation at 6 wap (49.4 cm) and 8 wap (43.5 cm). In addition, there was significant differences in the number of leaves at 6 wap (23.1 leaves per plant). In contrast, there was no differences in leaf greenness among treatments. At harvest, the number of bulbs was maximum at 75% basal dose recommendation of potassium chloride using drip fertigation (9.3 bulbs per plant). Moreover, the heaviest bulbs weight was obtained in the 75% basal dose recommendation of potassium chloride using drip fertigation (38.95 grams per plant). Hence, drip fertigation application significantly reduced the 25% potassium basal dose recommendation compared to the conventional system.Keywords: KCl, dose, irrigation system, bulb, potted research

Abstract

This study aimed to determine the effect of various doses of Smart K-Drip Fertigation on the growth and yield of shallots (Allium cepa L.) in dry land. The field research was arranged in a Randomized Completely Block Design (RCBD) consisting of one factor with 4 replications. The treatments were Control (Conventional/without Smart K-Drip Fertigation), K50 (Smart K-Drip Fertigation with a K-fertilization dose of 50% of the recommendation), K75 (Smart K-Drip Fertigation with a K-fertilization dose of 75% of the recommendation), K100 (Smart K-Drip Fertigation with a K fertilizer dose of 100% of the recommendation), K125 (Smart K-Drip Fertigation with a K fertilizer dose of 125% of the recommendation), and K150 (Smart K-Drip Fertigation with a K fertilizer dose of 150% of the recommendation ). The results showed that the dose of Potassium (K) 75% with the application of Smart K-Drip Fertigation gave the best results on shallot growth and yield parameters, and showed that fertilization with drip fertigation was more efficient than conventional fertilization. In conclusion, it can be stated that the use of Potassium in shallots can be reduced by 25% by fertilizing with drip fertigation in dry land.

Abstract

Tanaman Selada (Lactuca sativa L.) merupakan komoditi hortikultura yang memiliki prospek dan nilai komersial yang tinggi. Bertambahnya jumlah penduduk Indonesia serta meningkatnya kesadaran akan kebutuhan gizi, menyebabkan permintaan selada meningkat. Upaya yang dapat dilakukan untuk meningkatkan tanaman selada yaitu dengan cara melakukan pemupukan dan penggunaan varietas yang tepat. Penelitian ini bertujuan untuk mengetahui konsentrasi pupuk organik cair dan jenis varietas yang memberikan pengaruh terbaik terhadap pertumbuhan dan hasil tanaman selada. Penelitian ini merupakan penelitian eksperimen dilaksanakan pada bulan Januari  sampai Maret 2024 yang bertempat di Lahan Percobaan Fakultas Pertanian Universitas Sultan Ageng Tirtayasa. Rancangan yang digunakan pada penelitian ini yaitu Rancangan Acak Kelompok (RAK) yang terdiri dari dua faktor. Faktor pertama varietas tanaman selada (V) yang terdiri dari 3 taraf percobaan, yaitu V1 =Varietas new grand rapids, V2 =varietas kriebo, dan v3 =varietas Green coral. Faktor kedua yaitu konsentrasi pupuk organik cair (K) terdiri dari 5 taraf, yaitu K0 = Kontrol, K1 =3 ml/l, K2 =6 ml/l, K3 =9 ml/l, dan K3 =12 ml/l. Hasil penelitian menunjukan bahwa perlakuan konsentrasi K2 memberikan pengaruh terbaik terhadap parameter tinggi tanaman (22,17 cm), jumlah daun (23,33 helai), bobot basah (95,89 g), panjang akar (11,33 cm), dan bobot kering (3,82 g). Perlakuan varietas green coral memberikan pengaruh terbaik terhadap bobot basah (78,00 g), panjang akar (10,63 cm), dan bobot kering (3,68 g). Terdapat interaksi antara perlakuan konsentrasi pupuk organik cair dan perlakuan varietas tanaman terhadap panjang akar dan bobot kering tanaman pada kombinasi perlakuan konsentrasi pupuk organik cair 6 ml/L dan varietas green coral
