dc.description.abstractThe present investigation on "Influence of biofertilizers in combination with chemical fertilizers on growth, yield and quality of guava. [Psidium guajava L.) cv. Allahabad Safeda" was carried out during Kharif-Rabi season of the year 2011 at Horticultural Research Farm, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand. There were twenty treatments and the treatments comprising organic fertilizers (FYM), bio-fertilizers (Azotobacter, PSB 5ml/tree each), three levels of nitrogen (500, 375, 250 g N/ha), two levels of phosphorous (250, 157.5 g P/ha) and 250 g K/ha in all trees excluding absolute control were tried in Randomized Block design with three replications. For growth parameters the results revealed that treatment of 75% N + 75% P2O5 + 100% K2O+ Azotobacter 5ml/tree + PSB 5ml/tree was obtained significantly maximum tree height (3.80 m), girth of primary branch (28.67 cm), East West tree spread (5.20 m), North South tree spread (5.13 m) at harvesting stage while number of primary and secondary branches were recorded non significant effect at harvesting stage. For flowering characters significantly minimum number of days for flowering (32.33 days), maximum number of flowers per branch (25.33), fruit set per branch (90.20%) and fruit retention (92.96%) were recorded with treatment 75% N + 75% P2O5 + 100% K2O + Azotobacter 5ml/tree + PSB 5ml/tree as compared to rest of the treatment in guava cv. Allahabad Safeda. For fruit attributing characters like fruit diameter (10.07 cm), fruit weight (215.06 g) and pulp weight (193.44 g) were significantly increased under the treatment of 75% N + 75% P2O5 + 100% K2O + Azotobacter 5ml/tree + PSB 5ml/tree. As compared to other treatments the treatment of 100% N + 75% P2O5 + Azotobacter 5ml/tree + PSB 5ml/tree recorded minimum peel weight (15.00 g) and in treatment of 75% N + 100% P2O5 + 100% K2O+ Azotobacter 5ml/tree + PSB 5ml/tree recorded minimum weight of seeds (4.0 g). While, minimum number of seeds (111.33) were recorded in 100% N + 75% P2O5 + 100% K2O + Azotobacter 5ml/tree + PSB 5ml/tree. For yield attributing characters, number of fruits per tree (144.33), fruit yield per tree (32.13 kg) and per hectare (89.01 q) significantly increased under treatment of 75% N + 75% P2O5 + 100% K2O + Azotobacter 5ml/tree + PSB 5ml/tree as compared to rest of the treatments« For quality attributing characters, the total soluble solids (11.06° Brix.) was significantly increased under treatment 100% N + 75% P2O5 + 100% K2O + Azotobacter 5ml/tree + PSB 5ml/tree and shelf life of fruit (12.50 days) was significantly increased under treatment 75% N + 75% P2O5 + 100% K2O + Azotobacter 5ml/tree + PSB 5ml/tree as compared to rest of the treatments. From economical point of view, the highest net realization (1,58,221 ha-1) with CBR (1:8.99) was obtained in treatment T14 (75% N + 75% P2O5 + 100% K2O + Azotobacter 5ml/tree + PSB 5ml/tree) followed by treatment T8 (100% N + 75% P2O5 + 100% K2O + Azotobacter 5ml/tree + PSB 5ml/tree) as compared to rest of the treatments. For securing higher fruit 5yield and net realization, application of 75% N + 75% P2O5 + 100% K2O + Azotobacter 5ml/tree + PSB 5ml/tree was found beneficial for getting higher fruit yield in guava cv.
