Effect of different shading intensities on growth and yield of cherry tomato

Cherry tomato (Solanum lycopersicon var cerasiforme) is small size fruits, with a bright red colour resembling to cherry and becoming popular in the retail chains which are marketed at a premium price. The field experiment was conducted to study the effect of different (35, 50 and 75 per cent) shading intensities on growth and yield (qha-1 ) of cherry tomato. Significantly maximum yield was recorded in 35 per cent shading intensity and genotype Kalash Seeds Product (KSP)-113 (579.44 and 503.88 q ha-1 , respectively). Among the different shading intensities and genotypes, maximum plant height was observed in 75 per cent shading intensity and genotype KSP -113 at 30 days interval (74.70 and 60.95 cm, respectively). The minimum days to 50% flowering of cherry tomato were observed in cherry tomatoes grown under 35 per cent shading intensity (45.00 days) as compared to other shading intensities while minimum days to 50% flowering were observed in genotype KSP-113 (44.00 days). The maximum length of the cluster (9.58 cm), the weight of cluster (27.67 g), number of fruits per cluster (9.42) and number of pickings (11.67) were observed in 35 per cent shading intensities and in genotype KSP-113. The cultivation of KSP-113 genotype under 35 per cent shading intensity was found to be most sustainable for improving growth and yield of cherry tomato during the summer season

The end user’s perception about any developmental activity is priceless resource to policy makers for designing suitable policies and strategies to implement it effectively. Towards this end, the study was conducted in Pune district of Maharashtra with random sample of 30 agro-input dealers to measure the attitude of agro-input dealers towards eParwana eAgri services. Data were collected through well-structured interview schedule and analysed by using descriptive statistics and multinomial logistic regression. It was observed that about 53.34% of men agro-input dealers had favourable attitude, whereas about 66.67% of women agro-input dealers had most favourable attitude towards eParwana services. It was satisfying to note that overall 93.33% of agro-input dealers had favourable to most favourable attitude towards eParwana services. The maximum likelihood estimates indicates that gender and education were found to be positively significant at 5% level of significance.Not Availabl

Resonance Raman spectral isolation of the a and a3 chromophores in cytochrome oxidase.

Resonance Raman spectra of reduced CO-bound cytochrome oxidase obtained at two different excitation frequencies (441.6 and 413.1 nm) are compared with the spectra of the fully reduced enzyme. In the spectra of the CO-bound complex only the cytochrome a modes are strongly enhanced with 441.6 nm excitation and only the modes of the CO-bound cytochrome a3 heme are strongly enhanced with 413.1-nm excitation. In the fully reduced complex with both excitation frequencies, modes of both cytochrome a and a3 are enhanced. By subtraction we are able to uncover the complete spectrum of the fully reduced ligand-free cytochrome a3 heme. Thus, we report the discrete resonance Raman spectra of cytochromes a2+, a2+3, and a2+3 (CO). The spectra of fully reduced cytochrome a and ligand-free cytochrome a3 are very different especially in the low frequency region. Binding CO to ferrous cytochrome a3 results in electronic structure changes in the heme analogous to those in hemoglobin and myoglobin, from which we conclude that there is nothing electronically unique in the ferrous cytochrome a3 heme to account for its catalytic properties
