In two experiments carried out at the Scoresby Horticultural Research Station, with two growth regulators and plastic discs on maiden apple trees, branch angles were significantly increased. The growth regulators IBA and TIBA, and co-polymer plastic discs were applied at bud burst viz. when laterals were not longer than 5 cm in apple cvv. Jonathan, Granny Smith and Delicious (Hi-Early Sport). The application of growth regulators significantly increased branch angles, irrespective of apple variety or the branch position in the canopy. The plastic discs were more effective than either of the growth regulators.

Field experiments were conducted on gravel sandy soil of research farm of Horticultural Research Station, Seobag in Kullu valley with ten varieties of apple for three seasons (2008-2010). In the first crop season all the varieties matured within 157-188 days, while in the second and third seasons the crop matured with 159-179 and 156-187 days, respectively. The mean GDD accumulation from bud burst to fruit set was from 382 to 419° D and to maturity 2310 to 2957° D. The varieties, Mollice and Starkrimson consumed the lowest and highest GDD for attaining physiological maturity in different seasons among all varieties. But Commercial and Tydeman consumed the lowest and highest GDD for fruit setting. The photo thermal index (PTI) in all the varieties and seasons varied from 7.2 to 16.8 and 13.2 to 18.4° D/day at flowering and reproductive stages respectively.

An experiment on ginger was undertaken between April 2012 to March 2015 at Horticultural Research Station, Pechiparai with an objective to identify suitable ginger cultivar or accession with higher yield and quality attributes suitable for high rainfall zone of Tamil Nadu. Twenty four ginger genotypes, local strains and varieties were collected from different ginger growing tracts of India and evaluated for their performance in high rainfall region. Among the twenty four genotypes tested, the accession Z. O- 4 recorded higher fresh rhizome yield (22.16 ha-1) than other genotypes whereas Z. O - 6 recorded highest dry recovery per cent (22.47%). Higher oleoresin and fibre content was recorded in genotypes Z. O – 5 (9.56%) and Z . O – 17 (11.20%) respectively.

Data on fruit count corresponding to primary, secondary and tertiary branches of a randomly selected guava CV. Allahabad Safeda were recorded from the guava orchard of Horticultural Research Station, Birauli. The proposed sampling scheme in which the selection probabilities are based on length of braches between two forking points was compared with equal probability(PE), probability proportional to the number of branches(PPN), probability proportional to the cross sectional area (PPA) and probability proportional to volume (PPV) method of sampling and found to be more efficient.
