Kecamatan Hamparan Perak Kabupaten Deli Serdang memiliki luas lahan pertanian ± 11.046 ha atau 48, 9 % dari luas Kecamatan ini, dimana seluas 7.048 ha adalah lahan sawah yang potensial namun belum dimanfaatkan secara optimal. Berdasarkan UU No 41 tahun 2009 bahwa perencanaan pengembangan lahan pertanian pangan berkelanjutan harus berdasarkan pada kriteria kesesuaian lahan yang dapa dilakukan dengan dukungan penelitian. Penelitian ini bertujuan untuk mengevaluasi karakteristik tingkat kesesuaian lahan sawah dan lahan kering di Kecamatan Hamparan Perak Kabupaten Deli Serdang, untuk menganalisis usaha–usaha perbaikan yang perlu dilakukan dalam meningkatkan produktivitas tanaman dan untuk membuat peta kesesuaian lahan aktual dan kesesuaian lahan potensial tanaman padi sawah dan beberapa tanaman lahan kering di Kecamatan Hamparan Perak Kabupaten Deli Serdang. Metode analisisnya adalah dengan metode membandingkan (matching) menurut FAO. pemilihan satuan unit lahan berdasarkan peta tanah yang terdiri dari 12 titik bor dan 6 lobang profil. Hasil penelitian menunjukkan bahwa tingkat kesesuaian lahan untuk tanaman padi sawah (Oryza sativa) adalah cukup sesuai (S2) seluas 14.093, 883 ha dan sesuai marginal (S3) seluas 17.347,141 ha. Untuk tanaman jagung (Zea mays) termasuk cukup sesuai (S2) seluas 19.391, 019 ha dan sesuai marginal (S3) seluas 12.050,005 ha. Untuk tanaman kedelai (Glicine max) termasuk sesuai marginal (S3) seluas 31.441,024 ha. Untuk tanaman ubi kayu (Manihot utilissima) termasuk kelas sesuai marginal (S3) seluas 31.441,024 ha. Untuk tanaman ubi jalar (Ipomea batatas) termasuk kelas sesuai marginal (S3) seluas 31.441,024 ha. Untuk tanaman sawo (Achras zapota) termasuk kelas cukup sesuai (S2) seluas 17.660,583 ha dan kelas sesuai marginal (S3) seluas 13.780,441 ha. Untuk tanaman mangga (Mangifera indica) termasuk kelas sesuai marginal (S3) seluas 31.441,024 ha. Untuk tanaman sukun (Astocarpus astilis) termasuk kelas cukup sesuai (S2) seluas 17.660,58 ha dan kelas sesuai marginal (S3) seluas 13.780,44 ha.

Sub-optimal land is land that has low productivity due to parent material, physical, chemical, biological properties of the soil, rainfall, and extreme temperatures. To meet the availability of national food sources, it is necessary to utilize sub-optimal land that is widespread in mainland Indonesia. The purpose of the study was to determine recommendations for increasing sub-optimal land potential based on land suitability classes for several food crops, namely lowland rice, upland rice, cassava, sweet potato, corn, soybean, and peanut. The research was conducted in Stabat District, Langkat Regency from June to November 2020, and the Asian Agri Laboratory of North Sumatera Province. The research method used is the survey method, while to determine the suitability of the land, namely the matching method. Land potential in Stabat District can be increased by managing it in the form of recommendations for adding N fertilizer was 7,000 kg N/ha or the equivalent of 1,555 kg urea/ ha, the addition of P fertilizer was 158.8 Kg P2O5 or equivalent to 441 Kg SP36/ha, K fertilizer was 26.32 Kg K2O/ha or the equivalent of 43.86 Kg KCl. The adding organic matter or compost is 43.8 kg C-organic/ha or equivalent to 63.9 kg compost/ha.

Salinity is one of the problems in agricultural land in the world, including in Indonesia. Vetiver is quite tolerant of planting in saline soils at a certain level of salinity, but vetiver growth is inhibited at high salinity levels. The purpose of this study was to evaluate the effect of gibberellin in saline soils on the growth and production of vetiver (Vetiveria Zizanioides L.). This research was conducted in the greenhouse of the Faculty of Agriculture, Universitas Sumatra Utara, Medan. This study used a non-factorial completely randomized design, It was salinity stress (S) which consisted of 3 factors: Gibberellin concentrations of 0 (without treatment), 50 ppm, and 100 ppm. The results of this study indicate that giving Gibberellins in salinity stress conditions has a significant effect on the observed variables of plant height, specific leaf area, and cuticle thickness.

This study aims to examine the level and factors that influence the participation of oil palm planters ( Elaeis guineensis Jacq.) in marketing their products at the Multi-Business Consumer Cooperative in Pematang Bandar District, Simalungun Regency. The research method used is quantitative research with a descriptive approach. The implementation of this study was carried out in Pematang Bandar District, Simalungun Regency, involving 54 respondents. Primary data includes the characteristics of farmers who are members of cooperatives and the results of questionnaires from the independent and dependent variables. The data was processed using multiple linear regression test. The results showed that the level of participation was categorized as very high with a value of 84.1% and the variables of service quality, welfare of extension workers, knowledge of cooperatives, interest in cooperatives and member satisfaction had a significant effect on the participation of smallholders. The variables of the role of the extension worker and the ability of the administrators have no significant effect.
