Abstract

The concept of growth analysis has highly effective on the study of plant reaction in environmental condition. The determination of potential for the growth of plant will vary according to the environmental factors and nutrients application in form of fertilizer and bio-inoculants. The following study specifies the characterization of plant Moringa oleifera PKM1 variety by measurement of parameters like like Relative Growth Rate (RGR), Leaf Area Ratio (LAR), Net Assimilation Rate (NAR), and Secondary Metabolites (Biomass).

Keywords

RGR; LAN; NAR; Biomass

Introduction

Moringa oleifera (Horseradish tree) is the most cultivated species of a monogeneric family, Moringaceae native to the Sub–Himalayan tracks of India. Recently there is highly demand of some of the hybrid varieties of Moringa, especially variety PKM1 (South Indian origin) affecting the growth rate. The present study is to access the effect of different bio-inoculants and fertilizers on the growth and development of Moringa oleifera (PKM1) variety under green house condition as a part of rural livelihood support and also for the estimation of different growth parameters like Relative Growth Rate (RGR), Leaf Area Ratio(LAR), Net Assimilation Rate(NAR),  and Secondary Metabolites(Biomass).

Materials and Methods

Moringa oleifera PKM1 variety was used as the sample, the experimental set up was done inside the Green house maintaining the temperature 27-28⁰C and water was sprayed inside it. The experimental setup contains 2 trays, each of 48 small pots from the total of 96. The pots were filled with sterilized soil and sand through the entire surface area of each pot. Then the row marked as treatments and columns as replication. There were 12 treatments including control containing 8 replications each. Different fertilizers were added to the respective treatments one by one as per the quantity fixed above. There after water was sprayed & then the seeds sowing inside pot i.e. one seed per pot.

The day of sowing was count 0 day in observation. After 6 days it started to germinate with minimum height of 1c.m. The observation was taken in 15, 30 & 45 days of germination (Table-2).

Result and Discussion

Moringa oleifera PKM1 variety shows great response to different fertilizers. As from the above observation it conclude that  from the RGR analysis treatment no-1 with urea shows maximum RGR value i.e. 0.0097mg/gm/day, NAR value i.e.. 0.0343mg/cm2/day & LAR value i.e. 30.555cm2/gm. Biomass was estimated and was found better in treatment-2  in 45 & 60 days with SSP i.e. 0.765gm & 0.805gm respectively. So it concludes that RGR treatment T1 with urea is found beneficial over other application of Bio inoculants and fertilizers. This may be attributed to the uses of more Nitrogen by the plant.
