dc.descriptionAfield experiment was carried out at the Litchi orchard, Department of Fruit Science, College of Horticulture and Forestryduring 2019-20 to assess the effect of PSB and VAM with graded levels of Phosphorus on growth, yield and quality of Litchi (Litchi chinensis Sonn.). The design of experiment was three Factorial Randomized Block Design (FRBD) consisting of 12 treatments each replicated thrice viz. three levels of phosphorus (0, 400 & 600 g per tree), two levels of PSB (0 & 100 g per tree), two levels of VAM (0 & 100 g per tree) along with control.The combination of treatments were T1= P0S0V0 (Control), T2 = P0S0V1 (0g P+0g of PSB+ 100g of VAM), T3 = P0S1V0 (0g P+100g of PSB+ 0g of VAM), T4 = P0S1V1 (0g P+ 100g of PSB+ 100g of VAM), T5 = P1S0V0 (400g P+0g of PSB+ 0g of VAM), T6 = P1S0V1 (400g P+0g of PSB+100g of VAM), T7 =P1S1V0 (400g P+100g of PSB+0g of VAM), T8 = P1S1V1(400g P+100g of PSB+100g of VAM), T9 = P2S0V0 (600g P+0g of PSB+ 0g of VAM), T10 = P2S0V1(600g P+0g of PSB+100g of VAM), T11 = P2S1V0 (600g P+100g of PSB +0g of VAM), T12 = P2S1V1 (600g P+100g of PSB+100g of VAM).en_US
dc.description.abstractThe experimental results, all the treatments differed significantly with respect to growth parameters. Among the treatments, (T12) 600g of P + 100g of PSB + 100g of VAMreported the best values viz.,increase in plant height (8.43 cm), increase in canopy spread (E-W) (17.41cm). While, the treatment applied with 400g of P + 100g of PSB + 100g of VAM (T8) showed significantincrease in stem girth (6.73cm).The results pertaining to floweringand yield parameters revealed that, the minimum days from flowering to harvesting of fruits (76.92 days) was observed in the application of 400g of P + 100g of PSB + 100g of VAM(T8) and yield attributing parameters,the maximum fruit weight (22.74 g), the highest aril weight (14.16 g), maximum juice content (10.26 ml) and the highest fruit yield (20.38 kg/tree) were obtained by the treatment combination of (T12) 600g of P + 100g of PSB + 100g of VAM. However, the minimum fruit drop (60.20%) was observed in the treatment (T9) 600g of P + 0g of PSB + 0g of VAM. In biochemical parameters,the highest TSS (19.34 ˚Brix) and Vitamin C (76.30 mg/100g) was observed in treatment 600g P+100g of PSB+100g of VAM (T12) while the highest total sugar (25.49%) was observed in treatment (T11) 600g of P + 100g of PSB + 0g of VAM and the highest non-reducing sugar(11.76%) was obtained in the application of 400g of P + 100g of PSB + 100g of VAM (T8). For soil nutrient status, treatment (T6) 400g of P + 0g of PSB + 100g of VAM application exhibited the highest EC value 0.95 dSm-1and treatment(T9) 600g of P + 0g of PSB + 0g of VAM reported the highest organic carbon (2.28%) and available phosphorus (34.23 kg/ha) while the highest available potassium (113.04 kg/ha) was observed in treatment (T8)400g of P + 100g of PSB + 100g of VAM. Hence, from the evidences recorded, application of 600g P+100g of PSB+100g of VAM (T12) was found to be more effective for improving the growth, yield and quality of litchi as compared to other combinations.en_US
