An experiment was conducted at Indian Institute of Horticultural Sciences, Bangalore to study the effect of growth regulation through spacing and pruning on yield and quality of tomato hybrids (Lychopersicon esculentum Mill.) grown under control conditions. The results of present investigation revealed that tomato variety Sun 7611 (V2) recorded the higher (7.42, 7.90, 4.63 and 1.85) number of flowers per cluster at all the stages of crop growth and differed significantly from Arka Abhijith (V1). Where in pruning methods single stem (P1) gave higher (6.74 and 7.09) number of flowers per cluster at 30 and 60 days after transplanting, which were significantly different from P2 (double stem). Tomato grown on single-stem resulted in higher individual fruit weight (77.04 g) than double stemmed plants. Maximum yield of 2.23 kg/plant and 129.4 tonnes per hectare was recorded in plants having two stemmed plant, and the yield of 1.96 kg per plant and 114.38 tons per hectare was obtained from single-stemmed plants. Plants wider spacing gave the highest fruit weight (79.15 g) followed by medium spacing plants (73.92 g) and the least was recorded in closely spacing plants (69.07 g). Fruit yield per plant was significantly reduced under closer plant spacing (1.8 kg) and increased as spacing were increased.Keywords

Scented geranium (Pelargonium spp.: Geraniaceae) is an important, high value aromatic crop of South African origin. Due to high demand and price for the oil, an excellent potential exists for increasing cultivated area in India. An attempt was made to evaluate and characterize the available accessions of scented geranium based on their physico-chemical properties, chemical composition and odour assessment of the oil. There were seven treatments and four replications. All the accessions possessed light yellow coloured oil except PG-10, which possessed light green colour. The oil from PG-10 showed maximum acid value (3.02). The oil from PG-8 recorded the highest ester value (58.737). The oil form KB and CIMAP possessed maximum citronellol and geraniol content while, linalool was found to be maximum in case of PG-11. PG-10 contained maximum isomanthone (8.50%). The oil from PG-1 recorded the highest citronellyl formate content (15.83%). The essential oil was distilled during August from seven accessions upon GC analysis. The concentrations of isomenthone, citronellyl formate and citronellol were maximum in case of PF-10 (7.74, 23.18 and 37.07%, respectively). The major alcohols i.e., citronellol, geraniol, linalool and nerol were maximum in case of the oils of KB, CIMAP, PG-8 and PG-1 during May. Whereas, during August, PG-10 recorded the maximum nerol and cironellol whereas, PG-12 registered the highest concentration of geraniol and linalool. The rosy odour of different accessions is attributed to the presence of higher levels of geraniol, which is evident in the present case with the accession PG-12, during August. Hence, all the accessions differed significantly in all the parameters.Keywords
