Citation :- GROWTH AND YIELD PERFORMANCE OF CUSTARD APPLE GERMPLASM UNDER SCARCE RAINFALL ZONE.Indian Journal Of Agricultural Research.2011.(45):156- 160
Thirty five germplasm of custard apple have been evaluated for scarce rainfall zone under rainfed at Horticultural Research Station, Anantapur for 3 years from 2005 to 2007 in 10 years old trees for their growth and yield. The plant height per tree (3.2 m) was recorded highest in Phythota-3 followed by MMR-9 (2.91 m). Highest stem girth was recorded (37 cm) in Atemoya x Washington followed by MMR-8 (35.2 cm). Maximum plant spread was recorded in Bangalore (9.5 m3) followed by Atemoya x Balanagar (7.9 m3). The number of fruits was recorded highest (51.4) in Balanagar SR followed by Phythota-3 (45.3). The fruit yield was recorded highest (15.7 kg) in Ramaphal followed by MMR-10 (15 kg). Highest fruit weight per tree was recorded (278.9 g) in Atemoya X Balanagar followed by Y. Palli – 12 (270.6 g). Highest pulp weight (148 g) was recorded in Y. Palli – 12 followed by NLD-5 (123 g). Maximum peel weight (150 g) was observed in MMR – 9 followed by Ramaphal (124.1 g). Highest seed weight (22.6 g) was recorded in Balanagar SR followed by Bellary (20.9 g). Maximum T.S.S was observed (25.9%) in NLD – 8 followed by NLD – 10 (25%). Out of 35 germplasm evaluated the varieties vize; Atemoya X Balanagar (highest fruit weight), Y. Palli – 12 (highest pulp weight), NLD – 8 (maximum T.S.S), Balanagar SR (more number of fruits/tree) and Ramaphal (highest yield/tree) can be recommendable for scarce rainfall zone under rain fed conditions in poor fertile soils.
