ROSITA G. PERLADO. Don Severino Agricultural College, Indang, Cavite, June 1991. Intercropping Two Varieties of Eggplant with Okra, Bush Sitao and Mustard. Major Adviser: Dr. Eusebio V. Alava.
This experiment was conducted primarily to determine the effects of the different intercropping treatments on the growth, leaf area index and yield performance of eggplant as main crop, okra, bush sitao and mustard as intercrops.
Secondly, it also aimed to evaluate the economics of eggplant production and its adaptability to Cavite conditions, especially Trece Martires City.
Two varieties of eggplant, Dumaguete long purple (V4) and round variety (V5), bush sitao (BS5-3), okra (Smooth Green-EW Select) and mustard (Mustasa monteverde) were used in the study. The seeds were procured from Second Laguna de Bay Vegetable Irrigation Project. A month before planting eggplant seeds were sown in seedboxes two weeks before planting.
A 600 square meter area was properly cleared, plowed and harrowed twice. Three blocks were made as replication areas. Each block was subdivided into 14 subplots which served as the treatments. Randomized Complete Block Design (RCBD) was used in the experiment.
After land preparation, planting of the crops was done simultaneously. One-month old eggplant seedlings were planted into prepared plots. Mustard, okra and bush. Sitao were planted directly in the prepared plots.
Results showed that the monoculture eggplant outyielded both the intercropping treatments, eggplant + okra and eggplant + bush sitao except for mustard interplanted with Variety 2.
In general, eggplant varieties intercropped with mustard and bush sitao respectively yielded better than those intercropped with okra due to shading effect. Likewise, Eggplant + Bush sitao which ranked second in yield performance from those of eggplant + mustard showed better performance than when intercropped with okra.
Hence, the nitrogen fixed by legumes compensate for the nitrogen needed by the main crop. Although not significantly different from all intercropping systems, monoculture produced a much higher yield than the intercropped although after computing the total yield, intercropping gave the best performance.
This can be attributed to the number of plants per unit area.
Okra, although it is much taller than other crops, proved to be a good intercrop of eggplant because of its resistance to pest and disease infestation. Likewise as intercrop. they can compete normally for nutrient uptake in the soil.
Mustard, provided it is planted during fairly good weather condition can be a good intercrop. In fact, if not for heavy rainfall it can yield better and commands’ higher price during off season planting.
On the other hand, leaf area index contributed much to the yield performance of the different intercropping systems.
Considering the economics of production for each cropping system, eggplant interplanted with mustard gave the highest net profit. Okra on the other hand, added more yield to the main crop, however, it commanded a much lower price during its peak harvest.
As a whole, result showed that eggplant could be best intercropped with mustard to increase productivity per unit area of the land.
