Production Technology Developed

 

Name of the Technology Present status of adoption Remarks
Seeds of radish when produced from 15 Nov. to 1 Dec., are equally good as to their field performance in the next growing season, although seed yield declines gradually with delay in sowing but quality of seeds in respect of field performance does not deteriorate when sown within this period

 

 Farmers do follow this technology to an appreciable extent

 

 It is to be informed to the farmers especially who keep his seeds from his field for the next year growing

 
Kapasia   Variety   of   plantain   should   be   cultivated in Chittagong region The   information   was   Disseminated through some training and workshop

 

 Disseminated to  some extent
To increase the seed yield of cabbage variety Probhati under Joydebpur situation, 30 day old seedlings are to be transplanted within first fortnight of Nov. following 30 x 30 cm spacing

 

 The technology is followed at the research level but at the farmers level not much exploited Purification of the variety before seed production is needed and is going on

 
Slightly reddish to reddish tomato fruits are to be harvested for quality seed and after harvesting the fruits may be kept for six days in post harvest strorage without loss of quality of seeds

 

 Farmers do follow the technology to a considerable extent

 

 The technology is needed to be informed much to the end users through training

 
Medium   pruning   (heading   back   to   50% growth) Less  followed  by  the Extenstion work

is better to be adopted in Ber for farmers be done strongly higher yield and quality

 

 Less followed by the farmers Extension work is to be done strongly
Under the established mango tree, lalsak, spinach and bati  sak can be  successfully grown. Lalsak and spinach are much suitable than  bati sak cultivation

 

 

 

 

 Many farmers in Chittagong areas follow this technology May be dessiminated to the area of commercial mango cultivartion.
Second fortnight of March is the best time of  planting of Indian Spinach under Rajshahi region

 

 The adoption status is within acceptable range The grower sometimes plant before March to have the early crop but yield drastically reduces
Northen side of an established mango tree is best for higher yield and quality of Lalsak to be grown

 

 The technology is not much known to the growers and the mango growers do not follow

 

 Extension work is  needed

 
Application of NAA-200 ppm has a great influence in increasing the yield of bottle gourd whereas  for    moderate yield pollination is very much conductive

 

 Only hand pollination is    followed    by    the  growers

 

 

 Hormone   should   be used by the growers for summer bottlegourd
For the cultivation of sabri banana around pabna region, NPK @ 250 100 and 200 , kg/ha should be applied Followed       by       the growers to some extent Technolgy need to be

popularized     through

training/workshop/OFRD activities

 
November, January and March irrigation are suitable for higher yield of sabri banan under Rajshahi region Followed by the farmer to a considerable extent OFRD and DAE need to work much for further extension of

the technology
The homestead gardening “Kalikapur model” was    developed    and    recommended    for northern  part  of the   country   and   I  was  involved officially in developing this model Widely   followed and   accepted   by   the end users It    is    an    important

home   garden   model

for northern part of the

country

 

In relation to the Technology Development, I workded as a horticultural scientist in the FAO/UNDP Mango improvement and Development Project Phase-11 (BGD/8977044 vide memo no. Dir (R) BARI-206/90/2181 (65) dated 19-9-91 upto the first week of September 1992 with the then National Mango Consultant Dr. Kamal Uddin Ahmad posted at the RARS, Hathazari, Chittagong.

 Production Technologies Developed

 

  1. Growth and harvestable maturity of Red amaranth at different sowing dates

 

Harvesting of red amaranth at 20 days after sowing (DAS) was found to be suitable for November sowing considering economic yield as well as palatability. December sowing had moderate palatability with leaf stem ratio 1.38 on the other hand, in January sowing when harvested at 30 DAS expressed acceptable leaf stem ratio (1.71). Therefore, considering yield and optimum palatability, harvesting of the crop should be done at 25 DAS in December sowing and 30 DAS in January sowing.

 

  1. Effect of GA on seed germination and seedling growth of papaya

 

The treatment of papaya seeds with GA3 10 ppm for 24 hours, increased the germination percentage (88.25) and in seedling raised from those treated seeds attained higher plant height and produced higher number of leaves per plant.

 

  1. Effect of seed treatment with plant hormone on the growth and bulb production of onion

  1. Effect of spacing and fruit retention on yield and quality of okra seeds

 

The spacing 60 X 45 cm with first twenty fruits retention showed the best performance with respect to yield and quality of seeds of okra variety BARI Dheros-1.

 

  1. Screening of tomato germplasm tolerant to waterlogging

Twelve HnesWarieties of tomato were subjected to waterlogged situation for 24, 48 and 72 hours respectively following the establishment of the seedling after transplanting during rabi-season of 1997-98. Seven tomato lines were found as tolerant three moderately susceptible and the rest were highly susceptible under waterlogged situation.

 

  1. Screening of tomato germplasm tolerant to waterlogging

 

Seventeen HnesWarieties were kept under water logging situation for a period of 24, 48 and 72 hours respectively after the establishment of the seedling following transplanting during rabi season of 1997-98. Six brinjal lines were observed tolerant, six moderately susceptible and the rest were highly susceptible under waterlogged situation.

 

  1. Screening of some vegetable crops for salt tolerance

 

The experiment was done at Noakhali in collaboration with MCC during 1997-98 to select vegetable suitable to grow under saline conditions. Seed of IS tomato, 6 brinjal, 2 okra lines and one cultivar of Indian spinach were either sown or transplanted in farmers fields at different levels of salinity, such as, slightly saline (2-4 dsm ). It was observed that none of the vegetables were suitable to grow under moderately or highly saline conditions. However, 12 tomato (out of 17), brinjal, okra and Indian spinach lines\cultivar were found to maintain their normal growth and development at low level of salinity (2-4 dsm ).

 

  1. Influence of position and maturity of fruit on yield and seed quality of some tomato varieties

 

In BAR! Tomato 7, when fruits were collected from the first two clusters for seed purpose had the best performance at all stages and full ripe stage with regard to single fruit weight. This combination also produced the maximum number of seeds per fruit (239-274).

 

  1. Effect of plant growth regulator (LITOSEN) on the yield of tomato and brinjal

 

LITOSEN (nitro phenol) was sprayed twice, one at 15 days after seedling transplanting and other at fruiting stage in both tomato and brinjal crops. It was observed that the performance of LITOSEN treated plants was better than control. The treatment T4 (80 ppm) produced 9.89% higher yield in BARI Tomato-3 as well as 10.33% and 13.61% in brinjal varieties Uttara and Dohazare respectively.

 

  1. Effect of bio-stimulant (MIL STIM) on the yield of tomato and brinjal
