Abstract

Penelitian ini telah dilaksanakan di lahan Unit Pelaksana Teknis (UPT) Laboratorium Lahan Kering dan di Laboratorium Kimia Tanah, FakultasPertanian, Universitas Nusa Cendana dengan tujuan untuk mengetahui kemampuan zeolite dalam meningkatkan ketersediaan hara N asal pupuk NPK, pertumbuhan dan hasil tanaman jagung di lahan kering beriklim kering di NTT. Penelitian dirancang dalam percobaan faktorial menggunakan rancangan acak lengkap. Faktor pertama yang dicobakan adalah dosis pupuk NPK yang terdiri atas 4 level, yakni: tanpa aplikasi pupuk NPK (P0); 1/3 dosis anjuran pupuk NPK yakni 133,33kg.ha-1 (P1); 2/3 dosis anjuran pupuk NPK yakni 166,67kg.ha-1 (P2); dan sesuai dosis anjuran yakni 400 kg.ha-1 (P3). Faktor kedua yang dicobakan adalah dosis zeolit yang terdiri dari 4 level, yakni: tanpa aplikasi zeolit (Z0); 3t.ha-1zeolit (Z1); 6t.ha-1zeolit (Z2) dan 9t.ha-1 zeolit(Z3). Terdapat 16 kombinasi perlakuan yang dibuat dalam 3 ulangan. Parameter yang diamati adalah: kandungan N-total tanah, tinggi tanaman, total jumlah daun per tanaman dan bobot segar tongkol per tanaman. Hasil penelitianmenunjukkan: (1) peran zeolit dalam meningkatkan ketersediaan N asal pupuk NPK di dalam tanah terlihat hanya pada level perlakuan dosis pupuk NPK yang relatif tinggi. Pada level dosis pupuk NPK sebesar 2/3 dosis anjuran (267,66 kg.ha-1) dan sesuai dosis anjuran (400kg.ha-1), aplikasi zeolit dengan dosis 3 ton.ha-1, 6t.ha-1, dan 9t.ha-1 mampu menghasilkan kandungan N-total tanah yang nyata lebih tinggi dibanding perlakuan tanpa aplikasi zeolit; (2) aplikasi pupuk NPK sebanyak 1/3 dosis anjuran (133,33 kg.ha-1), 2/3 dosis anjuran (267,66 kg.ha-1) dan sesuai dosis anjuran (400kg.ha-1) mampu menghasilkan bobot segar tongkol per tanaman yang nyata lebih tinggi dibanding perlakukan tanpa aplikasi pupuk NPK. Walaupun demikian, antar perlakuan dosis pupuk NPK tidak terdapat perbedaan yang nyata pada bobot segar tongkol yang dihasilkan, sehingga tidak ditemukan perlakuan dosis pupuk NPK yang memberikan pengaruh terbaik terhadap hasil jagung pada penelitian ini; (3) aplikasi zeolit dengan dosis 9t.ha-1memberikan pengaruh yang terbaik terhadap bobot segar tongkol per tanaman jagung dibanding perlakuan dosis zeolit 3t.ha-1 dan 6t.ha-1.

Abstract

This research was conducted in Lakekun Village, Kobalima District, Malaka Regency from May to July 2023, aiming to determine the types of insect pests and natural enemies in mung beans. Data collection was carried out using direct observation techniques on mung bean plants and sampling using several traps. The types of traps used were pitfall trap, swepnet, yellow sticky trap, swing net and light trap. Sampling was done diagonally to determine the sample unit. The number of observation plots in the field is 3 observation plots. in 1 plot there are 5 sample units and a total of 3 observation plots there are 15 aub plots observed. Insect pests found on mung bean in the research location have three roles, namely as pests, predators and parasitoids. Species that act as pests consist of Artherigona exigua, Nezara viridula L, Aphis craccivora, Halyomopha halys, Riptortus linearis, Adoretus sp. and Gralliclava horrens. Insects that act as predators consist of Menochilus sexmaculatus, Coccinella transversalis, Orthhetrum sabina, Iscunara senegalensis. While insects that act as parasitoids are Tiphia femorata. The highest population found at the research site was Aphis craccivora which amounted to 315 individuals and the lowest population was Graliclava horrens with a total of 7 individuals. The value of the diversity index in mung bean plants is classified as moderate, namely 1.89. Keywords: diversity, insects, mung bean, identification.

Abstract

The purpose of this study was to determine the effect silver plastic mulch combined with the application of bokashi fertilizer on chili plants. This study was carried out from August to November 2021. This study had 18 treatment units consisting of: A1: planting media fertilized with bokashi and covered with silver plastic mulch, A2: growing media fertilized with bokashi and without mulch, B1: growing media fertilized with Urea, SP36, KCL and covered with silver plastic mulch, B2: growing media fertilized with Urea, SP36, KCL without mulch, C1: planting media fertilized with Urea, SP36, KCL + bokashi and covered with silver plastic mulch, C2: planting media was fertilized with bokashi + Urea, SP36, KCL, without mulch. The results showed that the use of mulch and bokashi gave better results (least pest infestation of all treatment), but statistically there was no significant difference between the treatments on the observed variables.
