The experimental method was arranged …
ABSTRACT The shallot plant has many benefits, namely as a seasoning for cooking and medicine. The production of shallot plants in Riau Province is still relatively low. The factor causing the low production of shallot plants is soil fertility. Efforts that can be made to improve soil fertility are by adding organic matter and liquid organic fertilizer (LOF). The study aims to determine the effe…
ABSTRACT White frangipani plant is an ornamental plant that is currently being much developed. The main problem in the development of white frangipani is sexual reproduction has a weakness, some of them take a long time, and genetic differences with the parent. So, the vegetative propagation as the alternative. One way of vegetative propagation by cuttings can be done, and the length of the cu…

ABSTRACT Sweet corn (Zea mays saccharata Sturt.) Sweet corn production from year to year decreased. One solution that can be done is to take advantage of the residual effect of fertilization on the first planting for the second crop. This condition occurs because of the high cost of producing sweet corn, which causes farmers to be reluctant to cultivate sweet corn. This study aims to determine …
ABSTRACT Corn (Zea mays L.) is the second important food crop after rice and some areas still use corn as a staple food in Indonesia.One of the problems faced in corn cultivation is the attack of the corn armyworm (Spodoptera frugiperda J. E. Smith). The corn armyworm S. frugiperda is an important pest in corn cultivation, because it can cause a decrease in production of 5-20% when the larvae …
ABSTRACT Podsolic has low fertility with has low pH, availability of P, Ca, Mg, and other macro nutrients impact to decrease productivity of sweet corn. The provision of AMF in order to support increasing nutrients, and dolomite as a source of Ca and Mg nutrients and increase soil pH has an impact on increasing other nutrients so as to increase the growth and yield of sweet corn plants needs t…
