Current study was undertaken to highlight the effect of pruning on improving vigor of old orchards and increasing performance in terms of fruit yield and quality under water and nutrient stressed condition of mid hills of Eastern Himalaya. Pengamatan yang diteliti yaitu panjang tanaman, umur berbunga, jumlah bunga betina, diameter buah, jumlah buah pertanaman, panjang buah, berat buah pertanaman, berat per buah dan potensi hasil. The study of one (year) indicates that half shoot (50%) pruning significantly influenced cropping pattern of guava. Effect of Pruning Techniques on Yield in High Density Planting of Guava (Psidium Guajava L.) cv. Fruit quality such as total dissolved solids, fruit acidity, and fruit diameter was not affected by pruning treatment. TDS is a measure of sugar and carbohydrate content in fruit juice, therefore the higher the TDS value, the fruit tends to get sweeter. Effect of shoot pruning and bending on yield and fruit quality in guava cv. Almost all the branches that leave the mother branches, produce flowers so they can leave the production. Teknologi degreening menggunakan gas etilen dapat memperbaiki warna kulit jeruk tropika menjadi jingga. quality by increasing TSS, sugars, ascorbic acid and pectin content of guava fruits. Rerata diameter dan bobot buah tertinggi diperoleh pada perlakuan pemangkasan pemeliharaan (P), yaitu 66,20 mm dan 143,75 g. Dari hasil analisis buah jeruk, total gula tertinggi (7,5%) dan total asam terendah (1,79%) diperoleh pada tanaman yang diperlakukan pemangkasan samping (S), sedangkan total karotenoid tertinggi (10,63 µg/g) terdapat pada tanaman yang diperlakukan pemangkasan lorong (L) dan kadar air yang tertinggi sebesar 90,08% dimiliki oleh tanaman kontrol (tanpa pemangkasan). Guava Tree Pruning Techniques Three types of cuts are used on guava trees: thinning cuts, heading back, and pinching. Results of the study suggest that side pruning treatment (S) can be recommended as the best pruning practice to farmers since it may produce highest number of fruits and sweetest taste. ABSTRACT The minimum flowering (232.80) was recorded in M 3 (Pruning of 30th May )guava trees. Haryana Journal of Horticultural Sciences, 35(3/4), 211-212 Syamal, M.M., & Rajput, C.B.S. The results of the present investigation indicated that, different pruning treatments and fertilizer levels produced significant effect on fruit quality of guava. combinations.
