  • The Scheme for Farm Cost Studies of Important crops in North Gujarat.

    The main objective of the study is to estimate the cost of cultivation / production of important crops of the state for providing the required data to the Government of Gujarat for policy implication. Three stage stratified random sampling technique was adopted for the selection of the respondents. In all, 419 farmers for Kharif crops, 437farmers for Rabi and Long duration crops and 176 farmers for summer crops were selected for the study. The data were collected by survey method for the year 2013-14. The information was collected through trained investigators and analyzed by using the simple average and ratio methods. The collected data were analyzed and presented in this report. The brief summary of the results is given in Table 1.

  • The Scheme for Creating a Permanent Machinery for Studying the Cost of Cultivation/Production of Principal Crops in Gujarat state.

    The data on cost of cultivation/production are periodically required by the state Government for principal crops grown in the Gujarat state for policy implication. The study on major crops of Gujarat viz; groundnut, paddy, bajara, cotton , wheat, mustard and gram has been taken up with the collaboration of the Directorate of Agriculture, Gujarat state, Gandhinagar, and Professor, Agricultural Economics, Junagadh. In our University, 21 clusters were thus selected for the study. The data were collected by cost accounting method. The brief summary of the result is given in Table 2.

  • Resource Use Efficiency and Returns to Scale in Production of Potatoes in North Gujarat

    The analysis of resource use efficiency in potatoes cultivation in north Gujarat indicated that even with the existing technology there is considerable scope for increasing income of potato growers. Farmers can put more land under potatoes cultivation if it is available. It is found that the plant protection measures were over use so cost can be reduce by reducing unnecessary use of plant protection chemicals. Return to scale for all groups of selected farmers shows decreasing marginal value product. Income can be still optimise on the basis of the prices of inputs and outputs.

  • Resource Use Efficiency and Returns to Scale in Production of Castor in North Gujarat

    The resources use analysis in castor farms indicated that even with exiting technology there is considerable scope for increasing the efficiency of resources use in castor by readjustment of resources as indicated above. In general all the resources were inefficiently used. Value of bullock labor, insecticides, fertilizers, and value of irrigation were underutilized and vlue of insecticides and value of irrigation were highly significant at 1% level and value of bullock labour was significant at 5% level. Whereas the efficiency scores of human labor, value of seed and value of manures were over utilized. Hence, the resources which were underutilized should be increased and those which were over utilized should be reduced in order to optimize the return from castor production.

  • Selection Index study for different genotypes of ashwagandha.

  • Potato seed multiplication through micropropagation.

    Results indicated significant difference for tuber yield among cultivars. Yield received from directly sown whole tuber of check varieties i.e. Kufri Pukhraj and Kufri Badshah gave higher yield i.e. 43333 kg/ha. and 36583 kg/ha. respectively. Potato tuber yield received from minitubers of tissue cultured plantlets var. Kufri Khyati (34389 kg/ha) was significantly higher than Kufri khyati check (27503 kg/ha). Numbers of tubers per plant were higher in tissue culture plantlets of Kufri Chipsona and Kufri Khyati as compared to plants raised from tubers. The results indicated that minitubers received from tissue cultured plantlets are suitable for multiplication of nucleus and breeder seeds.

  • Ex- situ conservation of medicinal plants.

    Total 171 different medicinal plant species were maintained which were herb, shrub, creepers or trees. Herbs of medicinal value were maintained in appropriate growing seasons in the botanical garden. The propagation material were collected from annual species and conserved for further use and distribution.

  • Development of protocol for micro propagation of Pomegranate(Punica granatum L.).

    The nodal segments (2-3 cm) of Bhagwa cultivar of pomegranate were used for mass multiplication through micropropagation in Murashige and Skoog (MS) media supplemented with various concentration of Auxin (NAA and IAA) and Cytokinins (BA, BAP and 2iP) with ten different combinations. The work is under progress.

  • Monitoring the quality of water in tube wells nearby area of Sujalam Sufalam Canal passed in North and North-West Gujarat.

    During the year total 20 water samples from the tube-wells nearby Sujalam Sufalam Canal were collected from the villages of Mehsana, Unza and Patan talukas and found that out of that 11 samples were falls under C3 and 9 were C4 category of salinity. In case of sodicity 07 samples were categorized under S1 and 12 were S2 and only one sample was in S3 category.

  • Long term effect of NPK fertilizers applied on the basis of soil test values with and without FYM on soil fertility and yield of cowpea – mustard – pearl millet cropping sequence

    The crop yield, N, P and K contents and uptake by seed and stover of cowpea (Kharif ), mustard (rabi,) and pearl millet (summer, ) were recorded. Application of FYM @ 10 t ha-1 to first crop of cowpea only recorded significantly higher yield as well as content and uptake of N, P, K by all the three crops (cowpea-mustard-summer pearl millet) grown in sequence. FYM application also significantly produced beneficial effect on fertility status of soil after the harvest of each crop. Looking to the effect of inorganic fertilizers, treatment receiving full recommended dose of N, P and K recorded higher seed and straw yields of all the three crops. In general, the full recommended dose of fertilizers to the concern crop resulted in higher uptake of nutrients and produced beneficial effect on fertility status of soil after the harvest of each crop.
