Abstract

Pollination in oil palm is generally carried out by insects. The beetle Elaeidobius kamerunicus is one of the effective pollinating insects for oil palm. This beetle breeds well on male flowers, this beetle can also reach female flowers located in the inner bunch, so this condition causes more perfect pollination. This study aims to determine the population of oil palm pollinating insects E. kamerunicus at several ages of oil palm plants which will be associated with environmental factors and ways of oil palm cultivation, both application of pesticides and fertilizers in Rasau Jaya District, Kubu Raya Regency. Insect sampling in this study used a purposive sampling method (determined sample), which used 3 plant blocks with different age groups of 4, 6, and 9 years respectively. The method used is the observation method, namely observing the population of oil palm pollinating insects directly on oil palm flowers. Observations were made on the population of E. kamerunicus by counting the number of E. kamerunicus visiting blooming oil palm flowers obtained from yellow sticky traps with a size of 20x30 cm placed near oil palm flowers. The results of the study concluded that the older the age of the oil palm plant, the greater the number of spikelets and the population of E. kamerunicus insects increased.

Abstract

Chili is one of the horticultural commodities that has a lot of nutrients and vitamins. Generally chili need sufficient nutrients in their growth and development so that the results can be maximized. Nutrients in the soil can not fully meet the needs of plant nutrients so that the addition of nutrients is required through liquid organic fertilizers from fruits. This research aims to determine the best concentration of liquid organic fertilizer from fruits on the growth and yield of chili plants on peat soil. This research was carried out in the experimental field of the Agriculture Faculty, Tanjungpura University Pontianak, in November 2017 to February 2018. This research used a Completely Randomized Design (CRD), with 5 treatment levels, namely k1 (5 ml /l), k2 (20 ml/l), k3 (35 ml/ l), k4 (50 ml/l), k5 (65 ml/l). Each treatment was repeated 5 times with 4 plants sample. Variables observed in this research include plant height, flowering time, plant dry weight, fruit length, fruit diameter, number of fruits, and weight of fruit per plant. The results of this research is the concentration of liquid organic fertilizer from the best fruits not found in this research but the concentration of 65 ml/l of liquid organic fertilizer can increase the growth and yield of chili plants on peat soil.

Abstract

Effect of Sludge and MKP Fertilizer Doses on Radish Plant Growth and Yield on Peatsoils. The development of the horseraean plant in peat land is faced with the number of obstacles in low, low ph, inlet, high c-organics with varying degrees of maturity and low - base base soils that are causing the growth and development of plants to be stunted, That would make a sludge delivery out of MKP fertilizer. The study is aimed at seeing the effect that doses of sludge given and MKP fertilizers have on the growth and growth of turnip plants in the peat soil. The research was conducted on KEP’S Agroland at Jl. Sui Raya Dalam, Pontianak City from March 12th to April 31th  2021. The study uses field experimental methods with comprehensive design prosecutions consisting of 2 treatment factors. The first factor is the sludge with the levels of treatment and the second factor is MKP fertilizer. Each factor is repeated 3 times, each denteronomy consisting of 4 plant samples, making the total number of plants 108. The first factor is the dose of sludge and the second is the dose of MKP fertilizer which has three levels of treatment each. Every treatment is repeated three times. A sludge dose consists of 0, 200, 320 g/polybag (equivalent to 0, 25, 40 tons /ha), while the MKP dosage consists of 0, 2, 4 g/polybag (equivalent to 0, 150, 250 kg/ha). The observed variabel is that of the number of leaves, the fresh weight of the plant, the fresh weight of the bulbous, the length of the tuber diameter and the plant’s dry weight. The research suggests and that there is no interaction between her and MKP for all variables. The treatment of sludge and MKP involving a dose of sludge 25 tons/hectares is equivalent to 200 g/polybag and MKP 150 kg/hectares is equivalent to 2 g/polybag is an efficient gift.
