Abstract

Plant intercropping that interplanted with young palm oil plantation indicated that there was change on ecosystem balance which resulted diversity alteration of insect as bio indicator area. The objective of the research was to obtain information on diversity of insect related to its intercropping system interplanted with young palm oil plantation. The research was conducted from December 2015 to February 2016 at privately-owned oil palm plantation, Kualu district, Kampar regency, Riau province. Descriptive methods by range survey on corn monoculture, soybean monoculture, bera, between corn and soybean intercropping in young palm oil area were used as experimental methods. Insect sampling was conducted by using pitfall trap, sweeping net and hand collection at 16 research units. The result showed that there were ten different insect ordo consisted of 50 families in all intercropping system sampled in this study. Diversity index (H’) reached as high as 3.07 with the best average (E=0.07) that was observed in soybean monoculture. Corn - soybean intercropping posessed the highest point of insect dominance (0.34), which is mean that there was only one kind of insect dominated on the community. The utilization of soybean monoculture system interplanted in young palm oil plantation is best to be used as a reference of ecological indicator on environment utilization, due to the reason that the existence of pest is balanced by the predator.

Abstract

The arrangement of planting time and corn defoliation is one of the efforts for increasing growth of corn and soybean in intercropping system. The purpose of this research was to study the effect of planting time and corn defoliation and their interaction to growth on corn and soybean and comparise the intercropping and monoculturer system. The experimental design used was factorial with two factors (2 x 3) + 2 monoculture treatments under randomize completed block design with tree replications. The first factor was planting time with two levels i.e. planting corn and soybean in the same time and planting corn 10 days after the soybean. The second was corn defoliation with three levels i.e. no defoliation, defoliation with four leaves left above the cob and defoliation of the adjacent and above corn cob. The results showed that growth of corn and soybean did not affected by planting time but the growth of corn was affected by corn defoliation. Plant height of corn on 6 and 9 weeks after planting was significantly increased when the corn planted 10 days after soybean and corn defoliation with four leaves left above the cob but this treatment was decreased dry weight plant. Intercropping system was not decreased leaf area and dry weight plant of corn and soybean.

Abstract

Water is an important factor for plant growth. Water-deficit in soil will affect plant growth and reduce productivity. The objective of this research was to defend seed viability, plant growth, yield, and seed quality on soybean in drought condition using GA3. The research was conducted at, Green House of Agriculture Faculty and Experimental Field of KP4 Gadjah Mada University in Kalitirto, Yogyakarta from September 2006 to January 2007. The research was arranged split-plot design 5x3 factorials with 3 replications. The Major plot was soil moisture content, which arranged in randomized complete block design, consisted of 5 soil moisture content levels; 100, 80, 60, 40, and 20% field capacity. The Sub-plot was the concentration of GA3 with 3 levels: 0, 100, and 200 ppm. The result showed that seedling growth was delayed by the decreasing of soil moisture content. It was revealed that 20% of the soil moisture content and immersion treatment in GA3 at 100 ppm significantly increased the seed vigor. Furthermore, immersion in GA3 at 100 and 200 ppm tends to increase the plant height and its hypothetical index vigor. The treatment also raises the dry-weight of seedling up to 60%. There was a positive correlation between GA3 concentration and leaf area.

Abstract

Utilization of organic material in crop farming is one of the methods to exploit the local wisdom in agricultural practice. The research was conducted from June to September 2012 in the research farm, State Islamic University of Sultan Syarif Kasim Riau. The objective of the research was to investigate the effects of organic materials and crop density ? in growth and yield on cucumber. Randomized block design with 2 factors and 4 replications was employed in this study. The first factor consists of three levels organic fertilizer treatments i.e. no fertilizer, poultry manure, and compost of oil palm empty bunch. Second factor comprises of three levels of crop density i.e. 1, 2, and 3 plants per pot).. The results showed that there was significant increase on growth and yield on cucumber with poultry manure treatment compare to that of with compost of oil palm empty bunch. Increasing crop density ? improves the number and weight of cucumber yield per pot, even though, some parameters, i.e. number of leaves, stem diameter, crop dry weight, productive number of branches, cucumber size and cucumber weight per plant were significantly decreased.

Abstract

Soybean is legume plant that has ability to symbiosis with Rhizobium. This process produces nitrogen thus decrease the need of urea fertilizer. The purpose of current research was to investigate the effect of Rhizobium and urea dosage on growth and yield of soybean. The research was conducted in experimental field of Agriculture and Animal Science Faculty of State Islamic University of Syarif Kasim Riau, started from May until July, 2012. Peat soil media and soybean cv. Wilis were used in this study. Randomized Completed Block Design with two factorials and three replications was employed for experimental design, in which the first factor was the Rhizobium (with/without Rhizobium application) whereas the second factor was dosage of urea fertilizer (0, 75, 150 and 225 kg/ha, respectively). The following parameters were observed e.g. plant height, number, weight and diameter of root nodules, flowering time, age of harvest time, number of pods/plant, number of seeds/pod, weight of 25 seeds, weight of dry seed/plant, weight dry plant, weight dry root and colour of leaf. The result showed that Rhizobium application increased the number of pods/plant. Urea fertilizer with dosage of 225 kg/ha increased number of seeds/plant, weight of 25 seeds, weight of dry plant, and weight dry seed. Interaction between Rhizobium and urea fertilizer were significantly different to weight dry root.

Abstract

Peat land conversion into oil palm plantations leads was increased emissions of carbon dioxide (CO2). Plants on peat land and environmental conditions believed to be factors in the emission of carbon dioxide (CO2). The porpuse of this research was determined the emissions of carbon dioxide (CO2) in oil palm plantations are intercropped with cropping crop on peat land and the influence of environmental factors on the emission of carbon dioxide (CO2). This research was conducted in September 2015 until April 2016 in Rimbo Panjang village, Subdiscrict Tambang, District of Kampar, Province of Riau. Cropping crop used were corn and soybeans. The method used in this study was a Random Block Design with four treatments and four replications. The treatments were palm - berau, palm oil - corn, palm oil - soybean, palm oil – intercropping (soybean – maize). Parameters measured were carbon dioxide (CO2), soil temperature, air temperature, the temperature of the lid, the depth of the water table and soil pH. The results showed that carbon dioxide emissions (CO2) in oil palm plantations are intercropped with cropping crop (corn and soybeans) were not significantly different. The influence of air temperature, soil temperature, the temperature of the lid, and the depth of the ground water level were inversely and  insignificant to the emission of carbon dioxide (CO2). As for getting nearly neutral pH, the emission of carbon dioxide (CO2) is increasing, but insignificant.
