Abstract

Effect of Cow Manure and Green Tonic Fertilizer on the Growth and Yield of Sweet Corn (Zea mays L. var saccharata Sturt).  Research purposes to determine the effect of cow manure and fertilizer GreenTonic on growth and yield of sweet corn.  The study was conducted from February 2013 to May, 2013, at Dingin Village, Muara Lawa Sub Distric of WestKutai.Distric.EastKalimantanProvince. Research purposes to determine the effect of cow manure and fertilizer Green Tonic on growth and yield of sweet corn. The study was conducted from February 2013 to May, 2013, in Dingin village, Muara Lawa Sub District of West Kutai District. East Kalimantan Province. Research design used 3x3 factorial experiment in a randomized block design (RBD) premises 3 blocks (replicates). Treatment factor I is Cow Manure (K), consists of three levels, namely: without the cow manure (k0), the dose of cow manure 10 tonnes / ha (k1), the dose of cow manure 15 tonnes / ha (k2). Treatment factor II is fertilizer Green Tonic (G), consists of three levels, namely: without fertilizer Green Tonic (g0), the concentration of fertilizer Green Tonic 1ml / l. water (g1), and the concentration of fertilizer Green Tonic 2 ml / l. water (g2). Treatment of cow manure (K) significantly different to the current parameters out male flowers and heavy cob. Significantly different cob diameter. Not differ significantly affect plant height at 30 days and 45 days, while female flowers out, ear length and cob production. Green manure treatment Tonok (G) significantly different to the cob diameter, cob weight and cob production. Significantly different when the male flowers out and ear length. Unlike tidaknyata the plant height at 30 days and 45 days, and while out female flowers. Treatment interaction (KxG) did not differ significantly affected plant height at 30 days and 45 days, while the male flowers come out, when out of the female flower, ear length, ear diameter, ear weight and ear production.

Abstract

Technical Efficiency of Coffee Farming in Tana Tidung Regency (KTT). This study aims to know the technical efficiency of a coffee farmin in KTT. This research was conducted in Tana Tidung precisely in the Buang Baru village as the coffee development center. Samples were taken of 30 people who have been producing coffee farmers. the data Analysis used to measure the technical efficiency  was stochastic frontier function with Frontier program 4.1.c.The results showed that the technical efficiency of a coffee farm in KTT was not efficient yet. The value of technical efficiency (ET) average farmer of 0.75 or 75%. Based on the results of the estimation of Stochastic Frontier production function with the MLE method on coffee farming which significantly affect the technical efficiency is negative and coffee farming is the outpouring of labor, the amount of the amount of herbicide and amount of manure. While the efficiency factors that influence real and positive is the amount of KCl. The factors that influence the production inefficiency is the number of family members.

Effect Of Application Time and NPK Fertilizer Dosage on The Growth of Sweet Corn (Zea Mays Saccharata Sturt), Sweet Boys Variety.  Research objectives: 1. To determine the effect of time and dose of NPK fertilizer and their interaction on the growth of rainbow corn crop. 2. Time and dose of NPK fertilizer on the growth of rainbow sweet corn is a good crop.The research was conducted in a randomized completc block design arranged (RCBD) with a 2 x 4 factorial analysis and repeated twice. The first factor when fertilizer (W) consists of three levels namely: w1 = initial planting, w2 = one month after planting. The second factor fertilizer NPK Pelangi (K) consists of four levels: k0 = Without NPK fertilizer (control), k1 = 61.2 g plot -1 equivalent to 100 g ha -1, k2 = 122.4 g plot -1 equivalent with 200 g ha -1, k3 = 183.6 g plot -1 ha -1 equivalenltol300g.Timing of fertilizer treatment (W) gives no real effect on the average height of plant age 15 days, 30 days, age at exit female flowers, male flowers, cob girth, wet production and production of the fruit cob cob without cornhusk but highly significant the plant height 45 days, ear length. Average yield of cobs without klobot wet weight was obtained on treatment w1 (NPK fertilizer rainbow After onelmonthloflplanting)lofl6.77ltonneslha-1. Treatment NPK Pelangi (K) highly significant effect on plant height age of 30.40 days, ear length, ear diameter, fresh weight of the fruit without klobot cobs and cobs without klobot production.

Abstract

Pest and Disease Identification Shorea leprosula Miq in Kutai National Park Resort Sangkima East Kutai regency of East Kalimantan Province. The purpose of this study were: (1) To determine the frequency of pest and disease types meranti Shorea leprosula Miq. (2) To determine the intensity of pests and defect types meranti Shorea leprosula Miq. (3) To determine whether or not the prevention and control of pests and plant diseases meranti types Shorea leprosula Miq. This research was conducted in the Kutai National Park Resort Sangkima East Kutai in East Kalimantan Province. This study was conducted for two months effective the month of August 2012 until September 2012.The results of the research area of 1 ha with observations census found 11 Shorea leprosula Miq trees, with one tree physically healthy, 8 mild stricken trees, one tree is being attacked, and 1 heavy stricken trees. Arise and the presence of pests and plant diseases are often referred to as crop pests on crops and forests natural forests are mostly human intervention. From the calculation of the frequency of attacks on research plots by 91%, which means that almost all types of Shorea leprosula Miq indicated no pests and diseases while 9% were healthy. From the calculation of the intensity of pests and diseases of plants Shorea leprosula Miq, including the intensity of the attack was broken by 29.5%. Based on the identification of some pests and fungal diseases like cancer, stem, leaves and termite holes. The research concluded that the frequency of pest and disease Shorea leprosula Miq by 91%, the intensity of pests and diseases of the damaged condition of the stand, including 29.5% with the intensity of the attacks, control of pests and plant diseases do not need to be done because the condition only affected stands were . Recommended based on observation of pests and diseases types Shorea leprosula Miq need for monitoring human activities that can lead to new pests and diseases in forests Resort Sangkima which can reduce the quality and growth of the forest it self.
