Abstract

Salinitas yang tinggi merupakan salah satu cekaman lingkungan yang mengakibatkan tanaman mengalami cekaman osmotik, ketidak seimbangan hara, toksisitas ion tertentu, dan cekaman oksidatif. Cekaman tersebut mempengaruhi hampir semua proses fisiologis dan biokimia serta tahap pertumbuhan tanaman. Fase perkecambahan dan pertumbuhan semaian adalah fase kritis terhadap cekaman salinitas bagi sebagian besar tanaman, termasuk kedelai (Glycine max L. Merr.), kacang tanah (Arachis hypogaea L.) dan kacang hijau (Vigna radiata L. Wilczek), sehingga ketahanan tanaman terhadap cekaman salinitas dapat dievaluasi pada fase-fase tersebut. Toleransi tanaman legum terhadap cekaman salinitas beragam antar spesies maupun varietas. Batas kritis tingkat salinitas berdasarkan penurunan hasil pada tanaman kedelai, kacang tanah, dan kacang hijau berturutturut adalah 5 dS/m, 3,2 dS/m,dan 1–2,65 dS/m. Pemahaman pengaruh salinitas terhadap pertumbuhan tanaman sangat berguna untuk menentukan strategi pengelolaannya. Informasi mengenai mekanisme toleransi tanaman terhadap salinitas dari aspek morfologis, fisiologis, maupun biokimia tanaman sangat diperlukan dalam mengembangkan kultivar yang toleran. Penggunaan kultivar toleran merupakan salah satu upaya mengatasi masalah salinitas yang praktis dan ekonomis.

Abstract

Intercropping soybean with corn on dry land with dry climate (DLDC) is an alternative program to expand the soybean cultivation harvested area. This study evaluated the effectiveness of fertilization performance in the intercropping of soybean-corn in DLDC. The experiment in this study was arranged in a randomized block design, consisting of seven fertilizer package treatments with four replications. The spacing between corn (Pertiwi 3) and soybean (Dena 1) was (50 cm x 200 cm) x 40 cm (2 plants/clump) and between soybeans (Dena 1) was 40 cm x 15 cm (2-3 plants/clumps). The observations consisted of soil analysis (pH, organic matter, total N (Kjeldahl), available P, Ca-dd, Mg-dd, K-dd, and Na-dd), soybean leaf chlorophyll index (45 and 60 days after planting/dap), plant height at (45 daps and harvest), number and weight of root nodules (45 daps); Corn: chlorophyll index (56 daps), plant height (harvest), analysis of corn and soybean plant tissue (60 daps), yield, and yield components of dry seeds of soybean and corn per hectare. The results showed that effective fertilization for the intercropped crops was 53 kg N + 1,500 kg of manure per hectare in corn plant and 7 kg N + 22 kg P2O5 + 18 kg K2O + 1,500 kg/ha manure + Rhizobium Iletrisoy/Agrisoy in soybean crops.

Abstract

Agricultural lands affected by salt facing complex problems associated with soil salinity and the toxicity effects of Na cation. Soil amelioration and mulching is an alternative to alleviate negative effect of salinity. Objective of research was to identify effective ameliorant, and effect of mulching in improving growth and yield of groundnut on saline soil. The research had been conducted on saline soil (soil EC 12 dS/m) in Lamongan during dry season of 2016, using Hypoma 2 cultivar. Treatments that consisted of two factors were arranged in a split plot design with three replicates. The main plot was mulching (without mulching and mulching with 3.5 t/ha of rice straw), and the sub plot was soil ameliorations (control, 120 kg/ha K2O, 750 kg/ha S, 5 t/ha gypsum, 5 t/ha manure, and 1.5 t/ha of gypsum + 5 t/ha manure). Results showed that mulching, and amelioration with 120 kg/ha K2O, 750 kg/ha S, 5 t/ha gypsum decreased soil EC, but could not improve groundnut growth and could not retard chlorophyll degradation because the soil was EC still high (12.5 dS/m). The higher yield (1.49 t/ha dry pods) can be obtained by amelioration with 750 kg sulphur/ha combined with mulching
