Performance of advanced potato hybrids for yield potential and suitability to Southern Dry Zone of Karnataka

Abstract

A field study was implemented on performance of advanced potato hybrids for three consecutive years from 2015 to 2017 during Kharif season at HREC, Hassan, Karnataka under AICRP-Potato. A total of eight hybrids were evaluated by adopting RCBD with four replications. The tubers were planted at 60 cm x 20 cm spacing with soil application of RDF (75:75:100 kg NPK/ha) and FYM (25 t/ha) as per the package of practices of UHS, Bagalkot. The hybrids such as AICRP-P-15, AICRP-P-16, AICRP-P-17, AICRP-P-18 AICRP-C-13, AICRP-C-17, AICRP-C-20 and AICRP-C-24 were adopted for evaluation studies. All hybrids were tested for marketable and total tuber yield during harvest at 75 and 90 days after planting. The pooled data of three years indicated that, hybrid AICRP-P-16 documented highest marketable tuber yield of 15.57 and 20.78 t/ha, total tuber yield of 18.18 and 24.42 t/ha at 75 and 90 DAP, which was on par with AICRP-C-24 (15.01 & 17.76 t/ha) of marketable tuber yield and (17.27& 20.02 t/ha) of total tuber yield at 75 and 90 DAP, respectively. Therefore, it was concluded that hybrid AICRP-P-16 was high yielding and found suitable for cultivation in Southern Dry Zone of Karnataka during Kharif season.
