Description Thesis-P
The present investigation was carried out during the year 2010-11 and 2011-12 at orticulture Research Centre, Patharchatta, Department of Horticulture, G.B.P.U.A.T., Pantnagar, Uttarakhand, to study the response of time of shoot pruning in meadow orchard of guava (Psidium guajava L.) cv Pant Prabhat. Two years old meadow orchard of guava plants was taken for this investigation. The treatments consisted of seven different combinations of time of half shoot pruning viz., pruning in April (T1); pruning in July (T2); pruning in October (T3); pruning in April and July (T4); pruning in April and October (T5); pruning in July and October (T6); pruning in April, July and October (T7) and one control (T8). In this way there were eight treatments replicated four times in Randomised Block Design with two plants as a treatment unit. Findings revealed that time of half shoot pruning significantly influenced the cropping pattern of guava. Half shoot pruning in April, July and October (T7) have positive effect towards managed plant growth and vigour viz., plant height, plant spread, plant volume
and shoot growth. Treatment T7 (PAJO) gave minimum annual increase in plant height, plant spread, plant volume and maximum number of flower buds/plant. Half shoot pruning in April (T1) gave lesser rainy season yield. On the other hand, during winter season, it gave more number of flower buds/ plants and fruit yield with heavier weight of fruit. Lowest yield was recorded with control plants in winter season. The treatment T7 (PAJO) was found superior in terms of fruit size, fruit weight, TSS, ascorbic acid and sugars content. The nitrogen, phosphorus and potassium content of guava leaves revealed that none of the treatments affected N, P and K content of guava leaves significantly. On the basis of results, it can be concluded that cropping pattern, fruit yield and quality of guava fruits can be influenced by time of half shoot pruning. For obtaining maximum winter season yield and profit from meadow orchard of guava, Half shoot pruning should be done in the last week of April.
