Safflower Cultivars | | Author Name : | | | MUHAMMAD FAROOQ1, ALI YAR KHAN, NAILA ILYAS2, MUHAMMAD NOMAN KHAN, ILTAF KHAN, MUHAMMAD BAKHTIAR | | Publisher : | | | Bridge Center | | Article URL : |  | | | Abstract : | | | Pakistan is facing harsh shortfalls of edible oils. Therefore, a
field experiment was conducted to check yield potential of various
cultivars grown under organic farming and to determine N uptake and
crop apparent N recovery of the manures by safflower. Organic
fertilizers were applied at the rate of 80 kg N/ha, FYM and Poultry
manure were applied. Results showed that Soil Nmin content was
considerable increased to 25% and 24% in FYM and PM after their
application as compared to its initial soil Nmin and reduced after harvesting of crop. Soil K also boosted after manure application
highest increase 78% noticed in PM followed by FYM which was 75%
and remain in increasing trend after harvesting of crop. Soil pH
increased the highest with the average of 0.74 was noticed in PM
followed by FYM which was 0.71 as compared to initial soilpH. Line
TN-79-683 had highest mean seed yield of 860 kg/ha while BI-20926
had lowest mean seed yield of 481 kg/ha. Highest dry matter yield
with the mean of 7817 kg/ha was noticed in TN-79-609, while lowest
dry matter yield with mean of 3459 kg/ha was noticed in BI-251289.
Harvest index was not significant different among treatments, but
among cultivars/lines there were great differences. Highest harvest
index of 14% was recorded from line BI-250538 followed by line TN79-683 which was 12.2%. PM application significantly increased seed
yield by 31% and dry matter yield by 20% as compared to the control. | | Keywords : | | | Organic Manures, Safflower Cultivar, Seed yield,
