Effect of integrated nutrient management on fruit quality of pomegranate cv. Ganesh

Abstract

A field experiment was conducted with integrated nutrient management treatments on 5 year old pomegranate cv. Ganesh. Total treatment combinations were seventeen viz, T 1-Recommended dose of NPK i.e. 500 : 200: 500 g NPK/plant, T 2 -Vermicompost (10 kg/plant) + Neem cake (5 kg/plant) +Karanj cake (5 kg/plant), T 3 -Vermicompost (10 kg plant) + 50% NPK, T 4 -Vermicompost (10 kg/plant) + 50% NPK + PSB (20 g/plant), T 5 -Vermicompost (10 kg / plant) + 50% NPK + Azotobacter (20 g/plant), T 6 -Neem cake 5 kg + 50% NPK ), T 7 -Neem cake 5 kg + 50% NPK + PSB (20 g/plant), T 8 -Neem cake 5 kg + 50% NPK + Azotobacter (20 g/plant), T 9 -Karanj cake (5 kg / plant) + 50 % NPK, T 10 -Karanj cake (5 kg / plant) + 50% NPK + PSB (20 g/plant), T 11 -Karanj cake (5 kg / plant) + 50% NPK + Azotobacter (20 g/plant), T 12 -Vermicompost (10 kg) + Neem cake 5 kg + 25% NPK, T 13 -Vermicompost (10 kg) + Neem cake (5 kg) + 25% NPK + PSB (20 g/plant), T 14 -Vermicompost (10 kg) + Neem cake (5 kg) + 25% NPK + Azotobacter (20 g/plant), T 15 -Vermicompost (10 kg) + Karanj cake (5 kg / plant) + 25% NPK, T 16 -Vermicompost (10 kg) + Karanj cake (5 kg / plant) + 25% NPK + PSB (20 g/plant) and T 17 -Vermicompost (10 kg) + Karanj cake (5 kg / plant) + 25% NPK + Azotobacter (20 g/plant). Result revealed that combination of vermicompost @ 10 kg + 25 per cent recommended dose of NPK + 5 kg Neem cake+ PSB 20g per plant significantly increased the quality components of pomegranate fruits in terms of TSS (16.95 • Brix) , TSS acid ratio (41.62), ascorbic acid (14.39 mg/100 g), total sugar (14.24%) and organoleptic score (8.51) as well as leaf and soil nutrient status as compared to recommended dose of NPK (500g : 200g: 500g).

Influence of Different Organic Sources of Nutrients on Yield and Quality of Pomegranate (Punica granatum L.) cv. Bhagwa

“…Such effects have been associated with increasing rate of translocation of photosynthetic products from leaves to developing fruits. These findings are in concordance with the results of Vanilarasu and Balakrishnamurthy [27] and Sangeeta et al [28] in banana, Meena et al [29] in pomegranate and Dey et al [31] in guava.…”

“…The lowest acidity in pomegranate fruits may be the fact that treatment application improves the soil condition and performed regulatory role on absorption of nutrients, translocation of carbohydrates into sugars and their derivatives by the reaction involving reversal of glycolytic pathway. These results are in accordance with findings of Sharma [23] in mango, Kundu et al [30] in ber, Babhulkar et al [26] in Nagpur Mandarin and Meena et al [29] in pomegranate.…”

“…Whereas, it was statistically noted minimum under recommended dose of FYM and NPK applied through chemical fertilizers treatment (Control) with the value of 15.26 °Brix. An increase in TSS with application of FYM and neem cake along with biofertilizers and biopesticides might be attributed due to [23] in mango, Babhulkar et al [26] in Nagpur Mandarin, Vanilarasu and Balakrishnamurthy [27] and Sangeeta et al [28] in banana and Meena et al [29] in pomegranate.…”

“…Nitrogen is essential for many metabolic processes involved in plant growth. According to [7], nitrogen is a necessary component of both protein and chlorophyll. Nitrogen and Phosphorous stimulate crop root activity and rooting patterns, enabling seedlings to start well before nitrogen fixation.…”
