Print. xvii, 126p. (Unpublished).https://krishikosh.egranth.ac.in/handle/1/5810178850The present experiment was carried out during the academic year 2019-20, at Shivar Block, Central Research station, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.). An experiment was laid out in a factorial randomized block design (FRBD) with nine treatment combinations and three replications comprising of three pruning intenites viz., 20 cm, 15 cm, control and three application of INM viz., I1 - 75% RDF(194g:94g:94g NPK/plant) +100g AM +100g Azotobacter +100g PSB +0.50Kg neem cake at onset of monsoon, I2 - Half N(97g) +Full P&K(94g:94g)+100g AM +100g Azotobacter +100g PSB +0.50Kg neem cake - Ist Application.1/4 N(48g) - IInd Application and 1/4 N(48g) - IIIrd Application. respectively at one month interval and control.An experiment entitled “Effect of severity of pruning and integrated nutrient management on yield and quality of custard apple” was carried out during the year 2019-20 at Shivar Block, Central Research station, Akola. with objectives to study the effect of severity of pruning on growth, yield and quality of custard apple, To study the effect of integrated nutrient management on growth, yield and quality of custard apple and to find out the combined effect of pruning levels and integrated nutrient management on growth, yield and quality of custard apple. An experiment was laid out in a factorial randomized block design (FRBD) with nine treatment combinations and three replications comprising of three pruning intensities viz., 20 cm, 15 cm, control and three application of INM viz., I1 - 75% RDF(194g:94g:94g NPK/plant) +100g AM +100g Azotobacter +100g PSB +0.50Kg neem cake at onset of monsoon, I2 - Half N(97g) +Full P&K(94g:94g)+100g AM +100g Azotobacter +100g PSB +0.50Kg neem cake - Ist Application.1/4 N(48g) - IInd Application and 1/4 N(48g) - IIIrd Application. respectively at one month interval and control. Regarding the application of pruning of 20 cm from tip showed the better performance in terms of plant height, number of shoots per branch, canopy of plant, leaf area, days to flowering, number of fruits per plant, yield, stony fruit percentage and fruit quality in terms of average weight of fruit, fruit volume, fruit to pulp ratio, pulp %, fruit set %, number of different grade fruit, total soluble solids, acidity %, T.S.S and acidity ratio, total sugar, reducing, non-reducing sugar. In respect of integrated nutrient management application (Half N(97g) +Full P&K(94g:94g)+100g AM +100g Azotobacter +100g PSB +0.50Kg neem cake - IstApplication, 1/4 N(48g) - IIndApplication, 1/4 N(48g) - IIIrd Application, respectively at one month interval) showed better performance in terms of plant height, number of shoots per branche, spread, canopy of plant, leaf area, days to flowering, yield, stony fruit percentage, and fruit quality in terms of average weight of fruit, fruit volume, fruit to pulp ratio, pulp %, fruit set %, number of different grade fruit, total soluble solids, acidity %, T.S.S and acidity ratio, total sugar, reducing, non-reducing sugar. Among the combinations of pruning and integrated nutrient management, the combined application of 20 cm pruning + Half N(97g) +Full P&K(94g:94g)+100g AM +100g Azotobacter +100g PSB +0.50Kg neem cake - IstApplication, 1/4 N(48g) -IIndApplication, 1/4 N(48g) - IIIrd Application showed the better performance in terms of plant height, number of shoots per plant, spread, canopy of plant, leaf area, Yield, Stony fruit %, Average weight of fruit, fruit volume, fruit to pulp ratio, pulp %, fruit set %, number of different grade fruit, total soluble solids, T.S.S and acidity ratio, total sugar, reducing sugar in custard apple cv. Balanagar. In overall study of present investigation, it was observed that that for getting the quality fruit yield of custard apple prunned the custard apple plant at 20 cm from the tip in the month of April and apply Half N(97g) +Full P and K(94g:94g)+100g AM +100g Azotobacter +100g PSB +0.50Kg neem cake as Ist application in the month of June, 1/4 N(48g) -IInd application in the month of July and 1/4 N(48g) - IIIrd application in the Month of August.EnglishThesis
