Abstract

Inorganic fertilizers is associated with reduction in some soil properties and crop yields over time. Application of organic fertilizer has positive effects in maintaining the soil properties. The aim of this research was to study the growth and physiology of peanuts on different doses of cow manure and NPK 16 fertilizers. The study was carried out in research field of the Laboratory of Ecology and Plant Production, Agriculture Department, Faculty of Animal and Agricultural Sciences Diponegoro University, Semarang. The design used was split plot. As the main plot was doses of cow manure (0, 5 and 10 tons / ha), subplots was NPK 16 fertilizer (0, 25, 50, 75, and 100 kg N / ha), with three times replications. Parameters observed were plant height, number of leaves, activity of nitrate reductase (ANR) and chlorophyll contents. There was interaction between manure and NPK 16 doses to total chlorophyll content of leaves. Separately, cow manure and NPK 16 significantly affected the plant height, ANR and total chlorophyll but not significantly effect on number of leaves. Cow manure and NPK 16 affected on increasing of plant height, ANR and total chlorophyll contents of peanuts.

Highlights

Peanut (Arachis hypogaea L.) is one of world’s largest legume crop which ranks second after soybeans
Peanut as one of the main commodities of Indonesia which its source of vegetable protein is important for food diversification in supporting national food security
Harvested area and peanut production in Indonesia have decreased in the 20132017 period

Summary

Introduction

Peanut (Arachis hypogaea L.) is one of world’s largest legume crop which ranks second after soybeans. Peanut has its own importance due to largest source of edible oil and its high nutritional value of kernel as human food, and haulm as animal feed. Peanut is world’s largest source of edible oil, ranks 13th among the food crops and 4th among oilseed crop [1]. That, it potential to be developed because it has high economic value and considerable domestic and international market opportunities. Harvested area and peanut production in Indonesia have decreased in the 20132017 period. The harvested area has decreased by 8.36% and the average production has decreased by 9.06% [3] Those average productivity is lower than its production potential and still cannot meet national consumption. Efforts should be aimed to remove the constraints responsible for its poor productivity
