Abstract

This study was conducted in Technical College of Applied Sciences, Sulaimany Polytechnic University, during 2017. Different levels of irrigation were used to production of okra plant. Complete Randomize Design used to layout of the experiment, with three level of irrigation in four replications. Yield, fresh weight of plant, dry weight of plant, yield response factor and different levels of irrigation were observed. The highest yield was given from treatment T1 (3.17 t/ha.) and the lowest was given from T3 (2.988 t/ha.). Also, the maximum fresh weight and dry weight of plant were given from T1 (61.40, 11.218 t/ha.), and their minimum was given from treatment T3 (57.00, 8.783 t/ha.). The highest water use efficiency and harvest index were obtained from T3 (1.615 kg.m-3, 0.095), and the lowest was given from treatment T1 (1.055 kg.m-3, 0.094). The crop response factor and the results in this study showed that the okra plants have a good response of water stress. As a result, we can recommend cultivating the okra at that time without irrigation in that region.

Abstract

Electrical conductivity (EC) of nursery medium will affect germination and growth of viola (Viola cornuta L.) seedling. The purpose of this study was to determine the influence of various ECs of growing medium on germination and growth of viola seedling. Research was carried out in December 2016 - January 2017 in nursery room of PT. Selektani Horticulture, Ngablak, Magelang. There were 9 EC treatments repeated 3 times therefore 27 units of experiment were tested. The observed parameters includeds germination rate (DB), and speed (KCT), plant height, number of leaves, shoot dry weight (BKBA) and root dry weight (BKA). Data were analyzed using regression and correlation tests. This study showed that there was a linear relationship between EC and DB as well as between EC and KCT. This is indicated by the following equations y = -20.771x + 99 504 (R2 = 0.9653, n = 27, y = germination (%), x = EC (dS / m) 0 HSS) and y = -5.1109x + 21.6 (R2= 0.8765, n=27, y= KCT (%KN/24hours). The critical EC needed to reach germination rate of higher than 80% was 0.94 dS/m. The correlations between DB and ec as well as KCT and EC were significant: respectively -0.98251 and -0.93621 (n = 27). The Relationships between EC and plant height, number of leaves, BKBA as well as BKA were quadratic. The optimum EC needed for seedling growth was 2.44-2.60 dS/m. The correlation betweenplant height and number of leaves was very strong as showed by the value at 0.9212. The correlation between BKBA and BKA was strong and this was indicated by the value of 0.7561.

Abstract

Tinggi muka air (TMA) dan suhu tanah merupakan dua kunci faktor lingkungan untuk mempelajari ekosistem lahan gambut dan sangat penting bagi kelanjutan ekosistem lahan gambut maupun kelangsungan produktivitas tanaman di lahan gambut. Di sisi lain, perubahan iklim merupakan faktor lain yang tidak dapat dihindarkan dan mempengaruhi ekosistem lahan gambut. Perubahan TMA dan suhu tanah akan menjadi lebih parah pada tahun El Niño atau tahun kering. Oleh karena itu, pemantauan TMA dan suhu tanah sangat penting untuk dipelajari bagi pengelolaan gambut berkelanjutan, terutama pada tahun kering. Penelitian ini bertujuan untuk mengetahui dinamika elevasi muka air dan suhu tanah di lahan gambut pada tahun El Niño, serta membandingkannya dengan kondisi tahun normal. Pengukuran TMA dan suhu tanah dilakukan secara otomatis pada perkebunan karet di lahan gambut di Jabiren, Pulang Pisau, Kalimantan Tengah, dari Bulan Januari sampai Desember 2015. Fluktuasi TMA lahan dan saluran di lahan gambut mengikuti variasi curah hujan. Walaupun rata-rata curah hujan tahunan pada tahun kering hampir sama dengan tahun normal, tetapi TMA dan suhu tanah menunjukkan perbedaan yang cukup nyata dengan tahun normal. Walaupun TMA lebih dalam dan suhu tanah cukup tinggi pada musim kemarau di tahun El Niño, tetapi lahan ini tidak terbakar dikarenakan ada tanaman produktif di dalamnya sehingga selalu terkelola dengan baik oleh pemilik.

Abstract

Ambon as the capital of Maluku Province had been occupied by 3,558 farmers whose farming works have contributed to the production of estate commodities for about 1,169 tons. There were three estate commodities with significant contribution, namely clove, nutmeg, and coconut. The objective of research was to analyze the characteristics of estate farmers and the contribution of estate commodities on household income. Sample was determined purposively from Nusaniwe District, precisely 30 farmers from Nusaniwe Subdistrict, 60 farmers from Latuhalat Subdistrict, 50 farmers from Amahusu Subdistrict, and 60 farmers from Urimessing Subdistrict. Total sample was 200 farmers. Data were collected using questionnaire and depth interview with key informant. Data on respondent characteristic were analyzed through simple tabulation. Income count was used to analyze the contribution of each estate commodity on household income. Result of research showed that education, number of household member, side-job selection, land width, and commodity species were not varying across subdistricts. Contribution of clove and nutmeg to household income was found as high for 70 – 80 %, while that of coconut reached only 10 – 20%. Side-job activity as fisher and construction worker gave contribution to household income for 5 – 10%.
