ABSTRACT

India consumes 7.8% of coal and 3.1% of the world’s petroleum (26.7 la. Barrels /day) and

ranks 3rd place in the coal consumption and 6th in the world in terms of energy consumption

respectively. But we have only 0.8% of the fuel resources in India with which we can meet

the requirement up to 22 % only. Moreover the fuel resources are getting degraded with over

consumption and there should be a supporting renewable alternative without which we need

to face a severe threat in the nearby future (Agarwal D & Agarwal A K, 2007). To overcome

this, several works are going on around the globe and even in India. In this regard, we have

concentrated on the production of biodiesel from Jatropha curcas L. which is a promising

substitute as it is cultivable even in waste lands (Akbar E et al, 2009) ( Chaudhury D R et al,

2007). The govt. of India has identified 400,000 sq. km (98 M. Acres) of such lands in which

Jatropha can be grown. A field work was conducted in Krishna District of Andhra Pradesh

to confirm the consistency in the seed output by adopting new strategies. Plants are grown in

different spacing and it is proved that with the increase in spacing the seed output is also

increased. The work is still going on to focus the possibility in the consistency of the seed

output, thus make it profitable to the cultivators by growing biodiesel farms and also making

it a sustainable renewable alternative to the limited fossil fuels by meeting the India’s total

biodiesel requirement of 36 MMT in 2011-12, at least up to some extent.

1. Introduction

Most of the countries in the world are striving hard to replace the fossil fuels, with bio diesel

and other eco friendly renewable energy resources to meet their fuel requirements. India is

having only 0.8٪ fuel resources, with which we can meet the requirement up to 20% ,for the

remaining we need to depend upon the imports. The difference between the consumption and

availability can be partly met by substituting it through bio fuels (Rao Y V et al, 2008),

chemically the mono alkyl esters of fatty acids which are produced by the transesterification

with Methanol or ethanol (Knothe, G. et al, 2006). Therefore, in recent years several

researches have been carried out to use vegetable oils as fuels in engines as biodiesel

(Pramanik, K. 2003).. Furthermore, the farmers would benefit by cultivating these crops in

rural areas (Akbar E, et al. 2009). Jatropha Sps. and Pongamia Sps. Are the well known

plants for the production of biodiesel, especially in the areas like Andhra Pradesh where the

biodiesel plant cultivation has been on the increase. About 2, 65,000 sq.km. waste lands are

proposed for growing Jatropha curcas. It is a native of tropical America, but now thrives in

many parts of the tropics and sub-tropics in Africa/Asia (Gubitz, G.M., et al. 1999). The

seeds of J. curcas yield an oil (30-40٪), which can be used as fuel for diesel-engine (Agarwal

D & Agarwal A K, 2007) and also useful as illuminant, lubricant and soap & candle-making

(Suhas P Wani et al, 2006).

2. Material and methods

The study was conducted at Nandigama mandal, Krishna district (Latitude: 16°10 N

Altitude: 81°08 E) in Andhra Pradesh (Figure 1). The climatic condition of the site is semi-

arid. The general characteristics of the soil are mentioned in Table-1. There is a significant

variation in the seasonal temperature. May is the hottest month of the year with a mean

maximum temperature of 40-45° C. The soil of the experimental site is black with fine gravel.

Soil analysis made for a no. of samples which were collected at the constant intervals (twice

/thrice in a month) using quartet method. Samples were taken at random at surface (0-6 cm

depth) and sub-surface (up to 15 cm depth) levels.

The plants were maintained at different spacings (3×2m, 2×2m, 1×1m). All these plants were

VAM inoculated at the time of implantation (one tablet /plant) to enhance the growth of

Mycorrhizae and have secondary roots as they were raised up by cuttings (Ratageri R H, et al.

2005). The soil is added with Gypsum initially and later Super Phosphate @150 kg/ha is

added. Drip is provided for supplementing the water. The physical growth, flowering, fruiting

and seed output are recorded for every 3 months in the study area and the results were

compared with various other plantations of Krishna district (Nandigama and Nuzvid plots)

for crowding effect, watering effect, nutrient effect.

3. Results and discussion

The growth performance of the experimental site is compared to that of other plantations of

Krishna district (Nandigama and Nuzvid plots). Analysis of soil samples indicated that as

plant spacing increased, the soil nutrient content also increased (Chaudhury D.R. et al, 2007).

This was confirmed by the presence of higher percentage of N, in the plots of 3×2m, 2×2m

when compared to the densest plot (1×1m). In the Nuzvid plot, where there is no proper

watering was done, poor growth is observed. In the drip plantation (experimental plot) not

only the vigour of the plant but also yield is also considerably good. In the experimental plot,

where fertilizers were applied, the flowering started by the end of the second year (Figure-2).

After pruning there was an increase in the number of branches (Sharma N and Sarraf A,

2007). Yield is reported by 2-3 kg/plant (Figure-3). On contrast to this, in other two plots

where fertilizers were not applied, the flowering is not reported even after the second year

and yield is also not reported so far. Plant density effects the growing space of the individual

plant and often used as a measure of competition. Though per hectare yield or biomass can be

greater at higher plant population but poor availability of water or soil nutrient may limit the

productivity. (Chaudhury D.R. et al, 2007).

4. Conclusion

Several reports have been observed and the information collected from the cultivators

revealed limitations for their large scale cultivation like inconsistency in the growth and seed

output, even in irrigated lands. Improved strategies are needed for water and nutrient

management to ensure optimal air conditions and suitable nutrient status and thus the yield

can be maximized. The work is still going on to derive the fruitful results by implementing

root zone management strategies and to find out the reasons for the limitations and also

favorable conditions for the large scale cultivation.
