Abstract
The present investigation entitled ‘Intercropping of annual flowers in Jasminum sambac L.’ was carried out at Floriculture Research Farm, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari during the year 2014-15 to study the suitable intercrops in jasmine. The intercrops grown were African marigold, French marigold and Gaillardia. The experiment was laid out in Randomized Block Design with ten treatments viz. T1 = Jasmine + African marigold (1:1), T2 = Jasmine + African marigold (1:2), T3 = Jasmine + French marigold (1:1), T4 = Jasmine + French marigold (1:2), T5 = Jasmine + Gaillardia (1:1), T6 = Jasmine + Gaillardia (1:2), T7 = Jasmine sole; T8 = African marigold sole, T9 = French marigold sole; T10 = Gaillardia sole. The results on effect of intercrops on the vegetative parameters of jasmine were significantly maximum under sole jasmine during both the intercropping season. Leaf temperature and PAR (Photosynthetically Active Radiation) of jasmine was found to
be non significant during first intercropping season while significant effect was noted with different intercrops during second intercropping season. Maximum bud diameter and bud length was recorded from intercropped jasmine though it was found to be non-significant. In case of yield, the highest yield was obtained from sole jasmine (2.80 t/ha) and least was noted in Jasmine + Gaillardia 1:2 (2.10 t/ha). Intercropping systems also had profound influence on different intercrops. On the basis of t-test, during first intecropping season all the growth and yield parameters of African marigold, French marigold and Gaillardia were found non-significant except crop duration while during second intercropping season, all the parameters of intercrops were also not found significant in comparison of sole cropping with 1:1 planting ratio of corresponding intercrops. But all the growth and yield parameters were significantly altered in comparison of 1:2 planting ratio with sole cropping as well as 1:1 planting ratio of coressponding intercrops.
The highest jasmine equivalent yield (9.67 t/ha) was recorded from the treatment T4 (Jasmine + French marigold 1:2). However, the lowest (2.80 t/ha) was obtained from the treatment T7 (Jasmine sole).
In view of the LER, significantly highest value was recorded from intercropping Jasmine + French marigold 1:2 (1.47) whereas lowest (1.0) from sole Jasmine. This shows profitability of intercropping over sole cropping.
From the economic point of view, highest net income per ha was recorded from Jasmine + French marigold 1:2 (Rs. 461460.53/ha) followed by Jasmine + African marigold 1:2 (Rs. 454066.12/ha) while the lowest was noted from sole cropping of Jasmine (Rs. 131464.97/ha). Maximum BCR (2.46) was recorded from jasmine + African marigold 1:1 followed by Jasmine + African marigold 1:1 (2.28), Jasmine + African marigold 1:2 and Jasmine + African marigold 1:2. The BCR of Jasmine + Gaillardia (1:1) and Jasmine + Gaillardia (1:2) was less than sole jasmine.
In terms of performance on the basis of JEY (Jasmine Equivalent Yield), Land Equivalent Ratio (LER) and profitability, Jasmine + French marigold (1:2) was found to be the best intercrop during first year of plantation. Profitability of french marigold can be attributed to its quality in combination with market price of the flowers.
