A study was carried out during winter (rabi) season of 2008 for developing new cultivars and in choosing suitable cultivars to grow in specific location on 16 tomato (Solanum lycopersicum Mill.) genotypes along with one check across 3 different locations, namely Dharwad, Saidapur and Belvatagi. Genotype x environment interaction was significant for most of the yield related traits suggesting that genotypes interacted significantly with environments. The difference in stability was due to both the linear response of genotypes to environment and deviation from the linear response. None of the genotypes was stable for all the characters and stability for one character was independent of stability for other characters. The genotypes 'TS 1', 'TS 6', 'TS 11, 'TS 14', 'TS 15' and 'TS 16' were found to possess stability for yield related traits. The analysis of quality parameters for all these genotypes revealed their superiority over check cultivar 'L 15' ('Megha').

Field experiments were conducted during bharif and rabi seasons of 2008-09 at GKVK, University of Agricultural Sciences, Bangalore, Karnataka to study the effect of intercrops and paired rows on growth and yield of maize (Zea mays L.). Under rainfed condition, maize intercrop with gardenpea (Pisum sativa L.) followed by frenchbean (Phaseolus vulgaris L.) areas was found better than fieldbean and soybean. Whereas the row ratio 2: 3 followed by 2: 2 proved better than 1: 1 with respect to productivity of maize. Among various intercropping systems, maize+gardenpea at 1: 1 row ratio significantly achieved higher in growth parameters viz., plant height, number of leaves and total dry matter production and yield and yield components viz., number of grains per cob, test weight, cob length, cob girth, maize grain yield and maize equivalent yield in maize+gardenpea at 2: 3 in paired rows over the other inter cropping system. Intercropping gardenpea proved compatible, remunerative higher price and less competitive with maize at 2: 3 ratios rather than 1: 1 and 1: 2 row ratios.
