Soft chemical routes to the synthesis of extended solid solutions of wurtzite ZnO-MO (M=Mg,Co,Ni)

Spray pyrolysis and gel decomposition have been used to generate extended solid solutions of MO (M=Mg,CoandNi) in the wurtzite modification of ZnO through kinetic limitations. Both routes yield a significantly greater extent of solution of CoO as compared to MgO and NiO. Published lattice stabilities for the wurtzite modifications of MO and the rock-salt form of ZnO are used to develop free energy-composition curves to relate the ease of solution to the driving force for partitioning. Reasons for the absence of single-phase rock-salt-based solid solutions are discussed

Synthesis of metastable, wurzite-based zinc oxide-cobalt(II) oxide solid solutions by spray pyrolysis

Aqueous solutions of acetates and nitrates of zinc and cobalt have been spray decomposed to study the production of extended solid solutions in the ZnO-CoO system. Examination of the products of a variety of synthesis conditions indicates that up to 70% CoO may be retained in the solid solution in the wurzite phase, even though a comparison of the equilibrium solubility in the phase diagram might be expected to favor the formation of a rock-salt-based solid solution

Farmer’s Perception and Efficacy of Adaptation Strategies to Climate Change in North Eastern Transition Zone of Karnataka State in India

A primary survey during the year 2021-22 was carried out among the 240 farmers of Bidar and Gulbarga districts of North Eastern Transition Zone in Karnataka to study the farmer’s perception on climate change for the period 1979 to 2019 and validate their opinions with the change in the meteorological indicators. About 74 percent of farmers expressed that there is a decline in crop yield while 83 percent of farmers opined that is a shift of employment from farm to non-farm activities during the period of forty years. Farmers practice various farm adaptation strategies activities to overcome the effect of climate change. Through Garatte ranking, it is revealed that most of the farmers prefer to practice alteration of sowing dates of crop (rank 1) as adaptation strategy followed by using of drought tolerant varieties (rank 2) and mixed cropping (rank3). Binary Logit analysis was used to identify the socio- economic attributes of households influencing the adoption of adaptation strategy to climate change. The results showed that, the variables like farm size, access to institutional credit, live stock ownership and climate information are the factors which positively shows significant influence on adoption. Economic incentives play an important role in the adoption of modern technologies. Access to institutional credit will support the farmers financially in adopting water conservation techniques like farm ponds, micro irrigation products

Impact of Krishi Bhagya Yojana (KBY) Farm Pond Technology on Semi-Arid Farmers in North Eastern Transition Zone of Karnataka State in India

Efficient water management through farm pond technology is a great initiative by Krishi Bhagya Yojana scheme in 2015. Out of 240 sample farmers, about 180 farmers are adopters and 60 are non adopters of farm pond technology in Bidar and Gulbarga districts of Karnataka. Majority of farmers prefer farm pond of size 30 m × 30 m × 3 m as during Kharif season with storage capacity of 2700 cubic metric which is able to   irrigate 1.5 ha land area .Through analysis, it is found that, the cropping intensity was increased to 225 per cent from 203.75  which accounts 9.47  per cent change  to that of the base year. The percent change in area under rabicrops was relatively more when compared with farm ponds which directly increase their income by sale of crops in market. The number of migrating people decreased from six to three persons after adoption of KBY by the beneficiary farmers. The most influencing factors in adoption of farm pond technology by farmers are access to rural credit, diffusion of information and adoption of high value crops
