University of Agricultural Sciences, Dharwad

The University of Agricultural Sciences, Dharwad was established on October 1, 1986. The University has 5 Colleges, 27 Research Stations, 6 Agriculture Extension Education Centers, 6 Krishi Vigyan Kendras and ATIC. The University has its jurisdiction over 7 districts namely Bagalkot, Belgaum, Bijapur, Dharwad, Gadag, Haveri, and Uttar Kannada in northern Karnataka. Greater diversity exists in soil types, climate, topography cropping and farming situations. The jurisdiction includes dry-farming to heavy rainfall and irrigated area. Important crops of the region include sorghum, cotton, rice, pulses, chilli, sugarcane, groundnut, sunflower, wheat, safflower etc. The region is also known for many horticultural crops. Considerable progress has been registered in the field of education, research and extension from this University.

    INVESTIGATIONS ON SEED TECHNOLOGICAL ASPECTS IN CHILLI (CAPSICUM ANNUUM L.)
    (University of Agricultural Science, Dharwad, 1999) BALARAJ, R; KURDIKERI, M B
    "FIELD EXPERIMENTS WERE CONDUCTED ON CHILI CULTIVARS VIZ., BYADAGI KADDI, DYAVANOOR LOCAL AND BYADAGI DABBA AT THE MAIN RESEARCH STATION, UNIVERSITY OF AGRICULTURAL SCIENCES, DHARWAD DURING KHARIF 1997-98 AND 1998-99 TO STUDY THE EFFECT OF SPACING, MOTHER PLANT NUTRITION, AND GROWTH REGULATOR TREATMENTS ON CROP GROWTH, FRUIT YIELD, SEED YIELD, AND QUALITY. STUDIES ON THE EFFECT OF HARVESTING STAGES ON FRUIT AND SEED QUALITY OF CHILI CULTIVARS WERE ALSO CONDUCTED. THE SEED QUALITY PARAMETERS WERE TESTED IN THE DEPARTMENT OF SEED SCIENCE AND TECHNOLOGY, UNIVERSITY OF AGRICULTURAL SCIENCES, DHARWAD. THE RESULTS OF THE STUDY INDICATED THAT WITH THE INCREASE IN SPACINGS 60 X 60 CM TO 90 X 90 CM) AND FERTILIZER LEVELS (100:50:50 KG N PK /HA TO 150:75:75 KG NPK/HA) THERE WAS SIGNIFICANT INCREASE IN PER PLANT TOTAL NUMBER OF FRUITS (68.13G TO 112.12 G)FRUIT YIELD (40.73 G TO 100.95 G) AND SEED YIELD (19.58 G TO 51.38 G). BUT HIGHEST PER HECTARE FRUIT YIELD (1357 KG/HA) AND SEED YIELD (675 KG/HA) WERE RECORDED IN CLOSER SPACING AT HIGHER FERTILIZER LEVEL FOLLOWED BY MEDIUM SPACING (1238 AND 623 KG/HA). A M O N G THE PICKINGS, THE HIGHER SEED QUALITY PARAMETERS VIZ. GERMINATION PERCENTAGE, SEEDLING LENGTH, SEEDLING VIGOR INDEX, SEEDLING DRY WEIGHT AND FIELD EMERGENCE PERCENTAGE WITH LOW E C OF SEED LEACHATE WERE RECORDED FROM FIRST THREE PICKING SEEDS OBTAINED FROM WIDER (90 X 90 CM) AND M E D I U M (75 X 60 CM) SPACING COUPLED WITH 150:75:75 KG NPK/HA. THE MAXIMUM NUMBER OF FRUITS PER PLANT, NUMBER OF SEEDS PER FRUIT, FRUIT YIELD AND SEED YIELD PER PLANT AND PER HECTARE WERE NOTICED WITH 20 PPM NAA, 1 PPM, 2,4-D FOLLOWED BY 50 PPM GAS AND 10 PPM NAA SPRAYED AT 35 AND 50 DAYS AFTER TRANSPLANTING. THE PLANTS SPRAYED WITH 20 PPM NAA, 1 PPM 2,4-D AND 50 PPM GA AT 35 AND 50 DAYS AFTER TRANSPLANTING RECORDED HIGHER SEED QUALITY PARAMETERS IN ALL THE FIRST THREE PICKINGS. IN ALL THE THREE VARIETIES, THE SEEDS OBTAINED FROM FULL RED COLOR FRUITS RECORDED THE HIGHER 1000 SEED WEIGHT, GERMINATION PERCENTAGE, SEEDLING LENGTH, SEEDLING VIGOR INDEX, SEEDLING DRY WEIGHT AND FIELD EMERGENCE PERCENTAGE WITH LOW E C OF SEED LEACHATE "
