The present study was conducted to assess the existence of genotype × environmental (G × E) interactions and stability for yield and quality related traits in pineapple using four varieties over seven locations during the year 2012-13. Pooled analysis of variance over seven locations revealed that the genotypic variances were highly significant for all the characters which revealed considerable genetic variability in the population. Stability parameters revealed that the genotype 'Amritha' was found better under poor environments. 'Mauritius' and 'Amritha' showed stable and consistent performance for all quantitative and qualitative traits whereas, 'Mauritius' had above average response and high stability in better environments for yield only. Thus, genotypes 'Amritha' and 'Mauritius' may be utilized in hybrid breeding programme to exploit their consistent performance in all order of yield.Keywords

Spentwash is an acidic liquid, rich in organic carbon, Ca, Mg, S and K with considerable amounts of N, P and micronutrients. The composition of spentwash indicated the scope of utilizing it as an amendment for the reclamation of sodic soil and as a cheaper source of plant nutrients. An incubation study was conducted to assess the changes brought in the properties of soil after the application of spentwash at 0, 55, 110 and 225 ml kg-1 soil. The samples were analysed for various physico chemical properties such as pH, EC, CaCO3, CEC, ESP, SAR and inorganic carbon contents. Application of spentwash @ 55,110 and 225 ml kg-1 soil were found equally effective in reducing the pH of air dried soil to = 8.3 during the incubation period of 60 days. The EC increased progressively and significantly with increasing rates of spentwash application. The ESP decreased from 32.3 to < 14 and SAR from 11.7 to < 8.0 for all the levels of spentwash. The addition of organic matter through spentwash enhanced the organic carbon content of the soil from 0.24 per cent to 0.62 per cent thus increasing the availability of nutrients to the soil.Keywords

An farm trial on integrated nutrient management in okra was undertaken at Krishi Vigyan Kendra, Kanyakumari to find out the combined effect of organic manures, biofertilizers and inorganic fertilizers over the traditional method in Okra hybrid CoBh H1 on yield, quality parameters and economic feasibility in Kanyakumari district. The trial was conducted during 2016 in five farmers field in a total area of 2 hectares located at Thuckalay block of Kanyakumari district. The assessment of integrated nutrient management was observed in Okra hybrid CoBh H1 with the technology options as recommended by TNAU CPG (2013) and KAU CPG (2011). The traditionally adopted farmers practice i.e., farm yard manure 25 t/ha+ imbalanced use of fertilizer was also included in the trial for assessment. Various yield parameters viz., days to 50% flowering, number of fruits per plant and yield (q/ha) and the benefit cost ratio was recorded for the individual farmer. Minimum number of days to flowering (52.0), higher number of fruits per plant (71.8), yield (274.8 q/ha) and cost benefit ratio (3.00) was registered with the technology as suggested by TNAU CPG (2013) wherein maximum number of days to flowering (55.2.0), minimum number of fruits per plant (47.6) , yield (230.2 q/ha) and cost benefit ratio (2.78) was recorded with farmers practice.Keywords
