Abstract

Corn is one of stupple food to support economic growth in North Sumatera. The purpose of this research was to obtain data on the ability of compost derived from coffee husks and arbuscular mycorrhizal fungi in the growth and production of sweet corn plants (Zea mays sccharata Sturt). The method used in this study is a randomized block design (RDB) in factorial, with 2 (two) treatment factors, namely: 1) Factor coffee skin and  2) arbuscular mycorrhizal fungi (M), each treatment was repeated two (2) times so that there are 40 experimental plots. The parameters observed are plant height, number of leaves, cob length, sample crop production per plot, crop production per plot, top wet weight, bottom wet weight, percentage of pest attack, colonization of arbuscular mycorrhizal fungi, effectiveness of treatment application to all parameters. The results obtained from this study were: 1) The giving of coffee skin compost did not significantly affect the parameters of plant height, number of leaves, cob length, sample plant production per plot, crop production per plot, top wet weight and bottom wet weight; 2) The allocation of arbuscular mycorrhizal fungi has no significant effect on the parameters of observing plant height, number of leaves, cob length, sample plant production per plot, crop production per plot, top wet weight and bottom wet weight; 3) The combination of coffee husks compost and arbuscular mycorrhizal fungi did not significantly affect the parameters of plant height, number of leaves, length of cob, sample crop production per plot, crop production per plot, top wet weight and bottom wet weight.

Abstract

Sweet corn (Zea mays saccaharata Strut L.) is one of the most staple food crops and has been demanded for decadest. Sweet corn has a great opportunity to be developed because it can be one of the main sources of carbohydrates and protein. One of the causes of the low production of sweet corn is the decrease in soil productivity due to nutrient leaching by rainwater, improper soil management, and soil fertility. This research was conducted by purponing a Split Plot Design of 2 treatment factors, namely; (1) Soil tillage factor (P) consists of 2 levels, (P1 = Minimum Soil Tillage and P2 = Intensive Soil Processing), (2) Organic Mulch (M) consists of 6 levels, M0 = No Mulch, M1 = Plastic Mulch, M2= Rice Straw Mulch, M3= Cocopeat Mulch, M4= Sawdust, M5 = Rice Husk Mulch. The results of this study indicated that the M2 treatment of rice straw mulch has a tendency to increase soil fertility and has significant effect on plant vegetative growth as production. Tillage was no significantly affect soil fertility and plant vegetative growth as production of sweet corn.

The purpose of this research was to determine the response of liquid waste utilization of palm oil on growth and production plant of kailan. This research was conducted by using Randomized Block Design (RBD) non factorial which consists of 4 levels of treatment are: L0 = Control (NPK 20 g/plot),  L1 = 1 l/plot,  L2 = 2 l/plot,  L3 = 3 l/plot. Parameters observed were height of plants, leaf number, stem diameter, fresh weight of harvest by plot, fresh weight of harvest by sample, fresh weight of sell by plot, fresh weight of sell by sample. The results of research showed that utilization of liquid waste of palm oil did not show significantly different results in all parameters of observation, but the liquid fertilizer from palm oil waste is able to compensate for the growth and production plant of kailan (Brassica oleracea L.) that fertilized with NPK.

Abstract

This research was conducted using a factorial randomized block design (RBD) method, which consists of two treatment factors, namely: 1) Aspirin administration factor with growth inhibitors with a notation (A) consists of 4 levels of treatment, namely: A0 = Control (without administration) Aspirin); A1 = administration of Aspirin at a dose of 1.25 g / l of water; A2 = Giving Aspirin at a dose of 2.50 g / l water, 2) Factors for giving cabbage waste compost with a notation (K), consisting of 3 levels of treatment, namely: K0 = Control (without giving cabbage waste compost); K1 = Giving cabbage waste compost at a dose of 10 tons / ha; K2 = Giving cabbage waste compost at a dose of 20 tons / ha, each treatment was repeated 3 (three) times. The parameters observed in this study were plant height, number of leaves, leaf color, stem diameter, number of tubers and production weight. As for the results obtained from this study, namely: 1) Giving Aspirin has a very significant effect on plant height, number of leaves, number of tubers and weight of production, but no significant effect on leaf color and stem diameter; 2) Giving cabbage waste compost has a very significant effect on plant height, number of leaves, number of tubers and weight of production, but no significant effect on leaf color and stem diameter; and 3) The combination of aspirin and cabbage waste compost has a very significant effect on the number of tubers and production weight, but has no significant effect on plant height, number of leaves, leaf color and stem diameter.
