Abstract

An experiment was designed with Randomized Complete Block Designed to investigate the effects of organic and inorganic nitrogen fertilizer at 90 kg N/ha on growth and leaf gas exchange in two varieties of Labisia pumila at 15 weeks after transplanting (WAT). In this study total biomass and photosynthesis (A) were significantly (P≤0.05) different among all factor. The results indicated that chicken manure enhanced the net photosynthetic rate (11.10 µmol/m²/s), stomatal conductance (0.40 mmol/m/s) and transpiration rate (5.30 mmol/m²/s) of L.pumila significantly after 31 weeks of planting. Chicken manure and Gobi indicated higher accumulation on total phenolic and total flavonoid compared to NPK green and control. Organic fertilizers (chicken manure and Gobi) were positively influenced the leaf gas exchange and growth of L.pumila as compared to the NPK green and control. This study proved that organic fertilizer can produce a quality of L. pumila compared to NPK green. Based on the principle of organic fertilizer which is slowly release from organic fertilizer will limit the nutrient availability for plant growth and allocate more carbon to produce secondary metabolites.

Highlights

The oilseeds sector is one of Ethiopia’s fastest-growing and important sectors, both in terms of its foreign exchange earnings and as a main source of income for over three million Ethiopians
Sesame production is increasing in Ethiopia especially in southwest and northwestern parts of the country which is driven by high market value and suitability of environmental conditions [4]
Descriptive statistical tools such as mean, variance, percentages and standard deviations were used in the process of examining and describing socio-economic and demographic characteristics of sesame producers and chain actors

Summary

Introduction

The oilseeds sector is one of Ethiopia’s fastest-growing and important sectors, both in terms of its foreign exchange earnings and as a main source of income for over three million Ethiopians. Sesame is Ethiopia’s second largest agricultural export after coffee in terms of source of foreign revenue earnings [1] It accounts for over 90% of the values of oilseeds exports from Ethiopia to the world. Different reports indicate that there is still potential arable land in different areas of the country to grow the crop and there is a considerable demand for Ethiopian sesame seed at international markets [1]. This indicates that, growth and improvement of the sesame sector can substantially contribute to the economic development at national, regional and family levels. Sesame production is increasing in Ethiopia especially in southwest and northwestern parts of the country which is driven by high market value and suitability of environmental conditions [4]
