Endive and Escarole. Returns: The market for eggplant is very volatile and prices per 20 pound box can vary greatly during the season. Yield 3 to 6 pounds per 10-foot row. Planting cowpea 2 weeks ahead of the main crop also produced the highest LER most likely due to more efficient utilization of sunlight, water and soil nutrients. There is a statistically significant fall in pesticide costs, 7,175 Taka per hectare (85 USD per ha), a 37.5% reduction. About 97% of eggplant harvest is produced for fresh market. Grow 12 to 16 plants per person. Follow @tylercowen, Learn more about Mercatus Center Graduate Student Fellowships. Email Alex Bt brinjal reduced the toxicity of pesticides as much as 76%. Follow @atabarrok, Tyler Cowen Yield in Eggplant Growing. Depending on growing season, variety, region and under best cultivation practices a farmer can expect a yield of 30 to 50 tonnes per hectare. Cultivation of Bt brinjal raises yields by 3,564 kg/ha. Our two primary outcomes were changes in yield and in pesticide costs. There were significant (p < 0.05) differences in the number of pods per plant in cowpea among the intercropped plots ().Significant differences (p < 0.05) were also present in seed yield per hectare among intercrops involving the semi-spreading cowpea cultivar.Cowpea planted 2 weeks prior to transplanting scarlet eggplant, produced the highest seed yield per hectare in both cultivars. Growth and fruit yield of scarlet eggplant were examined under intercropping with an erect and semi-spreading early maturing cultivars of cowpea in an additive intercropping model with scarlet eggplant as the main crop, in two dry seasons, under irrigation. Space plants 24 to 30 inches apart in rows 3 feet apart. Bt brinjal farmers used smaller quantities of pesticides and sprayed less frequently. Space plants 6 to 12 inches apart in rows 2 to 3 feet apart. There is a statistically significant fall in pesticide costs, 7,175 Taka per hectare (85 USD per ha), a 37.5% reduction. Reduction in fruit yield of the main crop, when intercropped with the semi-spreading cowpea cultivar was significantly (p < 0.01) greater than with the erect cowpea cultivar. Grow 2 to 3 plants per person. Garlic. Bt eggplant offers a 51% increase in yield, a 37.5% decrease in pesticide use, increased farmer profits and decreased farmer sickness. This statistically significant impact is equivalent to a 51% increase relative to the control group. Alex Tabarrok Grow 1 to 2 plants per person.

Farmers growing Bt brinjal and who had pre‐existing chronic conditions consistent with pesticide poisoning were 11.5% points less likely to report a symptom of pesticide poisoning and were less likely to incur cash medical expenses to treat these symptoms. Your email address will not be published. We implemented a cluster randomized controlled trial to assess the impact of genetically modified eggplant (Bt brinjal) in Bangladesh. There is a statistically significant fall in pesticide costs, 7,175 Taka per hectare (85 USD per ha), a 37.5% reduction. Enter your email address to subscribe to updates.

Privacy Policy, « Estimating Yields of Vegetable Crops and How Much to Plant, Fertilizer Side-dressing Vegetable Crops ». Competition between component crops was however most favourable for both cultivars of cowpea when planted 2 weeks ahead of scarlet eggplant. The yield of tomato could vary depending on the climate, soil fertility, the wealth of the farmer and the management styles of the farmers from place to place. Yield increases arise because Bt farmers harvest more eggplant and because fewer fruits are discarded because they are damaged. Eggplant. Container and Pot Sizes: How Much Soil Do I Need. We did not find evidence of heterogeneous effects by farmer age, schooling, or land cultivated. Yield increases arise because Bt farmers harvest more eggplant and because fewer fruits are discarded because they are damaged. https://doi.org/10.1016/j.scienta.2005.02.003.

In this study, we used a yield of 1300 boxes per acre, the most common yield level obtained from participant growers as the basis of our analysis. Yield increases arise because Bt farmers harvest more eggplant and because fewer fruits are discarded because they are damaged. Wow! Land equivalent ratio (LER) of the intercrops ranged from 1.38 to 1.94, indicating that the intercrops were more productive than the pure crops. Simultaneously planting cowpea and transplanting scarlet eggplant, is recommended for such additive intercropping system, aimed at full yield of scarlet eggplant with additional cowpea for food, income or fodder. Copyright © 2005 Elsevier B.V. All rights reserved. A very important result from Ahmed, Hoddinott, Abedin and Hossain in The American Journal of Agricultural Economics. Bt brinjal is a publicly developed genetically modified organism that conveys significant productivity and income benefits while reducing the use of pesticides damaging to human and ecological health. Email Tyler For a good yield, 20-25 tonnes of farmyard manure per hectare is incorporated into the soil at the time of its preparation. By continuing you agree to the use of cookies. Simultaneous planting of cowpea and scarlet eggplant produced 90–99% the fruit yield of sole scarlet eggplant, while planting cowpea 2 and 4 weeks ahead produced 65–80% and 58–60% of sole crop yield, respectively. Yield 8 fruits per Italian oval varieties; yield 10 to 15 fruits per Asian varieties. Bt brinjal farmers sell more eggplant and receive a higher price for the output they sell while incurring lower input costs, resulting in a 128% increase in net revenues. Our results are robust to changes in model specification and adjustment for multiple hypothesis testing. Cowpea was planted simultaneously with scarlet eggplant, 2 and 4 weeks ahead of scarlet eggplant.
