Продуктивность виноградников с различными формами кустов при полуукрывной культуре возделывания

В статье приведены данные исследований трех форм виноградных растений при полуукрывной культуре возделывания за 2005-2012 гг. На винограде сорта Первенец Магарача изучались формы: двусторонний косой кордон, односторонний горизонтальный кордон с резервным рукавом, двусторонний горизонтальный кордон с резервным рукавом. Виноградники 1986 года посадки, корнесобственные, неорошаемые, с площадью питания 3 х 1,5 м. В среднем за годы исследований по продуктивности насаждений выделена форма кустов «двусторонний горизонтальный кордон с резервным рукавом». Урожайность виноградников составила 14,2 т/га за счет более высокой нагрузки растений плодоносными побегами и их плодоносности.The article summarizes data from the study conducted in 2005-2012 on three shapes of vine plants under semi-covered vine growing. The following shapes were studied on the cultivar ‘Pervenets Magaracha’: bilateral oblique cordon, unilateral horizontal cordon with a reserve arm, bilateral horizontal cordon with a reserve arm. The vineyards’ profile: planted in 1986, own-rooted, non-irrigated, with the growing space of 3 x 1.5 m. On average, the vine trained as bilateral horizontal cordon with reserve arm stood out over the years of plantation productivity studies. The harvest of the vineyards amounted to 14.2 t/ha due to higher load of plants with fertile shoots and their fruitfulness.

LANSKAP PERKEBUNAN TEMBAKAU KEBONARUM DAN GAYAMPRIT KABUPATEN KLATEN

Klaten is a region in Surakarta residency in 18-20th century during Colonial era. It held an important role in the economy of Surakarta region during that period. Klaten became area with the highest plantation productivity in Surakarta. Several plantation companies were established in Klaten, including sugar industries, indigo plantations, and tobacco plantations. Today, several plantation infrastructures can be observed, and its historical background can be traced well, but researches about Klaten Colonial industries are seldom. There are operating tobacco plantations in Klaten Regency, located in Kebonarum and Gayamprit. Plantation area in Kebonarum and Gayamprit is used as research material. Survey and historical approach are used in this research. This project aims to explore the important role of Colonial plantations in rural societies, through archaeological environment phenomenon and its history. The existence of plantations in Klaten rural areas was able to offer social change to the societies in Colonial era.

MODEL PENINGKATAN PRODUKSI PERKEBUNAN KARET SEBAGAI SEKTOR BASIS DI PROVINSI JAMBI

This research entitled "Model of increasing rubber plantation production as the base sector in Jambi Province". This research started from the problem of low PDRB of regency / city in Jambi Province which has the potential to produce rubber. This phenomenon is related to the low productivity of rubber plantations in Jambi Province. In terms of rubber plantation has the potential to become the base sector in the region's economy. The production improvement model developed so far is still limited to multiple linear regression models. The problem of increasing rubber plantation productivity is much more complex. Therefore, this research will develop model of increasing rubber plantation production with simultaneous equation model and analyzed by Multiple Regression Model to obtain Model of productivity improvement of rubber plantation. This study will use secondary data released by institutions and related agencies, especially BPS. Data analysis will be done with eviews application program. The results of research will be useful as information for the next author's research in order to write a dissertation that the author is carrying out. The results of this study can also be used for policy making in increasing rubber plantation productivity. The results showed that 1) The development of rubber plantation production in Jambi Province is quite rapid, that in 2001 the production amount was 239,330 tons and in 2015 the production of rubber plantation increased to 350,457 tons. The growth rate is also quite convincing, ie an average of 2.65% per year. 2) The results showed that the regression model used in data analysis is good enough so as to explain the effect of independent variables of 96%. It can be explained also that the factors of rubber plantation area and the number of rainy days have a significant influence on rubber plantation production, while the variables of rubber farmers and rubber prices do not significantly affect the production of rubber plantations in Jambi Province. 3) The results also showed that the model of rubber price increase to two independent variables, the length of asphalt road and the capacity of rubber plant. However, the regression model obtained is not good enough to explain, where the variable length of the asphalt road and the capacity of the rubber plant is only able to explain 58% to the variable of rubber price in Jambi Province.
