 ABSTRACT

A field experiment was conducted during kharif 2016 at the Agricultural Research Station, Malagi, UAS, Dharwad to study the effect of GA3 with organic and in-organic supplements in KRH-4 hybrid rice seed production. The treatments imposed include T1: GA3 60 ppm, T2: GA3 60 ppm + NAA 50 ppm, T3: GA3 60 ppm + Boric acid 2%, T4: GA3 60 ppm + ZnSO4 0.5%, T5: GA3 60 ppm + Urea 2%, T6: GA3 60 ppm + 19 All 2%,  T7: GA3 60 ppm + Albizia amara leaf extract 2%, T8: GA3 60 ppm + Panchagavya 5%, T9: GA3 60 ppm + Jeevamrutha 5%, T10: GA3 60 ppm + Panchagavya 5% + Jeevamrutha 5%, T11: GA3 60 ppm + Panchagavya 5% + Albizia amara leaf extract 2% and T12: GA3 60 ppm + Albizia amara leaf extract 2% + Jeevamrutha 5%. The results revealed that, among the different combinations of in-organics or organics with GA3, the foliar application of GA3 60 ppm + Panchagavya 5% + Jeevamrutha 5%  recorded the highest number of productive tillers (9.5), highest panicle exsertion rate (84.34 %), seed set per cent (21.50 %) and seed yield per hectare (1320 kg) which was found on par with T11: GA3 60 ppm + Panchagavya 5% + Albizia amara leaf extract 2%. The study indicated that GA3 can be supplemented with organic formulations like Panchagavya, Jeevamrutha and Albizia amara leaf extract to enhance the seed yield as well as to reduce the burden of cost of seed production.

Key words: Hybrid Rice, GA3, Panchagavya, Jeevamrutha, Albizia amara
