The study was carried out at the Fruit research station, Sangareddy, Sri Konda Laxman Telangana State Horticultural University, Hyderabad during the period of October, 2016 to February, 2017 (Hasta bahar crop) to find out the effect of crop load on growth attributes of guava (Psidium guajava L.) cv. Allahabad Safeda under meadow planting system. The treatments of the experiment were crop load levels i.e. retaining of 5, 10, 15, 20 fruits per plant and control (No thinning) and second factor as a observations recorded after fruit thinning i.e. (1) 30 days after fruit set (2) 60 days after fruit set (3) 90 days after fruit set and (4) at the time of harvest for to study the growth and development of fruits with crop load levels. The ages of the plants were 4-5 years. The experiment revealed that the significant differences were noticed in guava cv. Allahabad Safeda for fruit growth parameters studied in hasta bahar crop. Fruit length, fruit diameter and fruit weight of guava fruits increased continuously from the initial stage of fruit development till maturity and up to harvest. The increases in fruit weight and diameter were comparatively more between 90 to at the time of harvest and 60 to 90 days after fruit set than 30 to 60 days after fruit set where the increase in fruit weight and diameter was slow. The difference of fruit growth and development was shown after 30 days after fruit set. The crop load of 5 fruits per plant recorded highest fruit length (7.34 cm), fruit diameter (4.46 cm) and fruit weight (236.46 g) at the time of harvest followed by 10 fruits per plant and lower fruit length (3.43cm), fruit diameter (3.48cm) and fruit weight (40.07) at the time of harvest in control (no thinning).
