Abstract

A strategic alternative step for the development of cultivation of feed crops is to optimize the use of dry land that has the potential for agricultural and livestock business. One of the forage plants that has good adaptation to less good soil condition and is a pioneer plant, Pueraria javanica legume, so it can be considered as a potential alternative forage as animal feed. The research aims at determining the effect of various levels of drought stress treatment on the plant hight, fresh matter production, dry matter production and root biomass of Pueraria javanica legume. The experiment was conducted in the Greenhouse of the Agriculture Faculty of Universitas Sumatera Utara. The experiment was carried out using a completely randomized design (CRD) with 3 treatments and 4 replications. The treatments were A1 (25% field capacity (FC)=144 ml/polybag, A2 (50% FC)=288 ml/polybag and A3 (100% FC)=576 ml/polybag. The results show that Pueraria javanica legume can survive and grow up to severe drought stress (25% FC) but the crop production does not increase when compared to the field capacity condition; besides, the legume cannot survive longer in drought condition. The volume of water supplied corresponding to the field capacity makes the plant growth better.

Abstract. The purpose of this research was to analyze the marketing system and marketing channel of chicken eggs and to analyze marketing efficiency based on marketing margin, price share and profit ratio of chicken egg cost in Pematangsiantar Municipality of Simalungun District. This research was conducted for two months, from July to August 2017. The methods used in data collection were: sampling of breeders and other marketing institutions selected by snowballing sampling technique and data collection methods was done by interviewing techniques using questionnaire. Data analysis included: marketing costs, marketing margin,farmer share and profit cost ratio of each marketing channel. The results of this study indicated that there were four marketing channels. The marketing margin on the Channel II showed the smallest cost margin and the largest profit margin so that it showed the largest cost-benefit ratio. The largest farmer share was obtained on the Channel IV but this channel  used only the retailers as an intermediate channel (one level) and relatively few exchanged eggs. So it was concluded that the Channel II was the most efficient channel becauseof the smallest cost and that the  profits were spread evenly among all the marketing institutions that play a role. The need for chicken eggs in Pematangsiantar Municipality was supplied from outside the city (63.33%) and filled by breeders from within the city(36.66%).

Abstract

The breeding of dwarf elephant grass generally uses vegetative methods, namely using cuttings. The constraints faced and the distribution of cuttings are the nature of which are easily damaged during storage due to physiological activities and invasion of microorganisms. This study aims to find a number of preservation techniques that can maintain the age and quality of dwarf elephant grass cuttings (Pennisetum purpureum cv mott.). This research was carried out in the Faculty of Agriculture Universitas Sumatera Utara, starts from July to August 2018. The design used is a 5 x 5 factorial complete randomized design (RAL), with 4 replications each consisting of 3 cuttings. The results showed that the general condition of the cuttings planting material was better until storage for 20 days, namely A4; the average shrinkage weight of the cuttings is significantly different in the A4 (refrigerator) treatment that is equal to 1.532 and the longer it is stored the higher the weight loss; the average power grows is significantly different in treatment A1 (wax) which is equal to 1.950 and the longer it is stored the lower the power to grow cuttings. The average vertical height is significantly different from the A1 treatment (wax) with a value of 10,585.
