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

Polymer electrolytes for a rechargeable li-Ion battery

Lithium-ion polymer electrolyte battery technology is attractive for many consumer and military applications. A Li{sub x}C/Li{sub y}Mn{sub 2}O{sub 4} battery system incorporating a polymer electrolyte separator base on novel Li-imide salts is being developed under sponsorship of US Army Research Laboratory (Fort Monmouth NJ). This paper reports on work currently in progress on synthesis of Li-imide salts, polymer electrolyte films incorporating these salts, and development of electrodes and cells. A number of Li salts have been synthesized and characterized. These salts appear to have good voltaic stability. PVDF polymer gel electrolytes based on these salts have exhibited conductivities in the range 10{sup -4} to 10{sub -3} S/cm

Not AvailableFarmer’s perception about any developmental activity is priceless resource to policy makers for designing policies in order to reduce vulnerabilities of farmers. A scale was developed to measure the farmer’s perception towards Integrated Farming Systems based on Likert’s technique of scale construction. A list of 50 positive and negative (60:40) statements indicating the perception of farmers was prepared according to suitability of study. The statements were edited in the light of fourteen informal criteria suggested by Edwards. The remaining 37 statements out of 50 were sent to the 60 judges who were the experts in the field of Integrated Farming Systems for rating on three point continuums. The total individual score of judges was calculated by summing up the weights given by judges to the individual statement. On the basis of total individual scores of judges, the top 25 per cent of judges with the highest total scores and the bottom 25 per cent of judges with lowest total scores were taken as assuming that these two groups provide criterion groups in terms of which to evaluate the individual statements. On the basis of calculated ‘t’ values for all statements, 15 statements (11 positive and 4 negative) were retained in the final scale. This scale can be used to measure farmer’s perception beyond the study area with suitable modifications.Not Availabl
