Abstract

Faktor ketersediaan air tanah menjadi faktor pembatas pertumbuhan dan hasil kedelai. Oleh karena itu tujuan penelitian adalah mengetahui pengaruh pemberian berbagai level kadar air tanah terhadap pertumbuhan dan hasil tanaman kedelai varietas Grobogan. Tata letak penelitian dengan Rancangan Acak Kelompok (RAK), terdiri atas 4 perlakuan pemberian air sebanyak kadar air tanah 25% kapasitas lapang (P1), kadar air tanah 50% kapasitas lapang (P2), kadar air tanah 75% kapasitas lapang (P3), kadar air tanah 100% kapasitas lapang (P4). Masing-masing perlakuan diulang 6 kali. Data penelitian terdiri atas prolin daun, stress index (SI), tinggi tanaman, berat kering tanaman, jumlah polong per tanaman dan berat biji per hektar. Data dianalisis dengan Analisis Sidik Ragam dan dilanjutkan dengan Uji Beda Nyata (BNJ) dengan taraf kepercayaan 95%. Pemberian air mempengaruhi produksi prolin, pertumbuhan dan hasil tanaman kedelai varietas Grobogan. Akumulasi prolin dalam tanaman semakin meningkat ketika tingkat cekaman kekurangan air semakin tinggi.  Pemberian air 75% kapasitas lapang mengakibatkan cekaman kekeringan tanaman kelas rendah, sedangkan tinggi tanaman kedelai, bahan kering tanaman, jumlah polong, dan berat gabah tidak berbeda nyata dengan pemberian air 100% kapasitas lapang. Pemberian air 50% kapasitas lapang mengakibatkan cekaman kekeringan tanaman kelas sedang dan secara nyata menurunkan tinggi tanaman. Pemberian air 25% kapasitas lapang mengakibatkan cekaman kekeringan tanaman kelas tinggi dan pada kondisi demikian terjadi penurunan secara nyata pada tinggi tanaman, berat kering tanaman,  jumlah polong dan berat biji per hektar serta terjadi penurunan hasil hingga 69% jika dibandingkan dengan pemberian air 100% kapasitas lapang.

Abstract

The yellow leaf curl (YLC) disease is one of plant disease generally found in chili pepper. The aim of the research was to know various concentrations of lime juice and synthetic citric acids to protect chili pepper (Capsicum frutescens L.) against YLC disease. The research used a randomized completely block design using seven treatments and three replications. The treatments tested were spraying lime juice of 0.1%, 0.2%, and 0.3% volume per volume (v/v); citric acid solution of 0.1%, 0.2%, and 0.3 % weight per volume (w/v). Control was used water only. The data result were analyzed using the honestly significant different test at the 95% confidence level. The treatment of both lime juice and citric acid solutions 0.2% and 0.3% could decreased whitefly population on chili pepper compared with control. The lime juice and citric acid solutions 0.3% was able to reduce the incidence and intensity of YLC disease. Lime juice and citric acid solution of 0.2% and 0.3% increased fruit numbers and fruit weights compared with control. The lower whitefly population decreased disease incidence of YLC (with regression Y = 5.7505x – 48.029). Intensity of YLC disease decreased fruit numbers and fruit weight (correlation value of -0.949 and -0.912). Keywords:  Citric acid, Chili pepper, Gemini virus diseases, Whitefly.

Abstract

Dieng is a plateau region, with an altitude about ± 2095 meters above sea level. Dieng Plateau is unique land because that has low air temperature and soil dominated Andisol and has various land slope from 0 percent until >40 percent. Therefore, Dieng Plateau is ideal land for horticultural cultivations. The serious problem in Dieng Plateau was conducted intensively conversion the forest area to the various land use system, to example for land potatoes cultivation, settlements and tourist activity. These conditions increasing hazard for the rate soil erosion. High soil erosion rate will decrease the soil fertility.This study aims to determine the level of soil fertility with indicators of soil microorganisms in a various of land use, given the high levels of soil erosion. The layout design of the research used is a Randomized Complete Block Design (RCBD). Analysis of the data used is Analysist of Variance – ANOVA (F test), Honestly Significant Analysis (5%) and Stepwise Regressiont. To determination the number of carbon biomass of microorganisms is applied with fumigation-extraction method. Fordetermination of total soil microorganisms using NA media, where as the determination of soil respiration using Verstraete method.The results showed that the land is sloping physiography (tourist land and residential) have higher fertility than high physiographic area, as a result of soil erosion. Different case for protected forests, although a high physiographic land, forests have higher fertility than the land potatos cultivation. Forest area are still natural, and its has a vegetation litter and diversity of vegetations, therefor the forest area has good barrier water runoff that carries organik material and soil salts.
