Done By;Pauline M. Ndwiga Reg. No. A56/64387/2010

OBJECTIVESOVERALL OBJECTIVE• To identify strategies of producing high yields and good quality

African night shade vegetable

SPECIFIC OBJECTIVES• To evaluate thirteen African nightshade species for performance.

• To assess the efficacy of plant extracts for pest control on two African nightshade species

• To evaluate organic amendments for the control of plant parasitic nematodes of two African night shade species .

MATERIALS AND METHODSEXPERIMENT I

Evaluating African night shade genotypes on performance Thirteen African night shade genotypes planted in plots of 2m by 2m

and a spacing of 30cm by 15cm.

Experimental design; Split plot design

Location of experiments; Open field environment

Treatments; DAP and CAN, Farmyard manure, No fertilization

Data collected; Plant height, yield.

EXPERIMENT 2 Assessing the efficacy of plant extracts for pest control on

two African nightshade speciesExperimental crop; Two African night shade genotypes planted in

plots of 2m by 2m and a spacing of 30cm by 15cm

Experimental design; Randomized complete block design

Treatments; plant extracts of garlic, pepper, a mixture of the garlic and pepper, abamectin and no spray

Data collected; Pest population, efficacy of the treatments.

Location of experiments; Open field environment.

EXPERIMENT 3Evaluating organic amendments for the control of

Nematodes of two African night shade genotypes

Experimental crop; Two African night shade genotypes planted in pots (three plants per pot).

Experimental design; Randomized complete block design

Treatments; chicken manure, cow manure, nematicide and no Treatment

Data to be collected; Percentage (%) increase or decrease of nematodes in each treatment.

Location of experiments; Green house environment

Discussion

• The results indicates that ANS require fertilization in order to achieve better yields.

• The yields significantly increased with application of

fertilization.

Plan to completion

• Experiment 1; Data analysis to be completed by 10th Aug 2012

• Experiment 2; Data analysis to be completed by 17th Aug 2012

• Experiment 3; To be set up on 30th July 2012 and end in 21st

Sept 2012 (8 weeks)

• Compiling data and writing up to end by Sept 2012
