The initial growth of turmeric is rather slow and takes about 4-5 months to cover the inter space. Therefore, the available space between the rows of turmeric could be effectively utilized by growing short duration crops like, vegetables, cereals etc. Hence, it is worthwhile to explore the possibilities of growing compatible crops with turmeric. With this background the experiment on effect of intercrops on growth and yield of turmeric was conducted at Agricultural Research Station, Bhavanisagar. Among the different intercrops, turmeric with cowpea recorded the maximum fresh rhizome yield per hectare (30.78 t ha -1 ) while turmeric + bhendi registered the maximum B:C ratio (2.68:1). Monocropping of turmeric recorded the lowest B:C ratio (1.67:1) among all the treatments.

The present field experiment was aimed to evaluate the tolerance level to shoot, fruit borer infestation, and yield traits with 174 brinjal accessions at the University orchard, Department of Vegetable crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore. Among the evaluated accessions, the Acc- EC 490062, Acc - EC 144139-D and Acc - IC 344646 were identified as the best performers as they showed favorable effects for earliness to flowering and harvest, number of fruits per plant and yield. In addition, they recorded the lowest level of shoot and fruit borer infestation with a high marketable yield. The least incidence of shoot borer (13.97 %) was registered in the accession EC 144139-D, EC 490062 (14.35 %), followed by the accession IC 344646 (15.74 %). Whereas the minimum infestation of fruit borer was recorded by the accessions EC 490062 (13.18 %), EC 144139-D (13.52 %), and IC 344646 (13.67 %). The maximum marketable yield per plant (3.46 kg) was registered by the Acc - EC 490062 followed by Acc - EC 144139-D (3.80 kg) and Acc- IC 344646 (3.64 kg). The genotypes acknowledged in the current investigation can be explored as parents in future crop improvement programmes of brinjal.
