    Response of greengram (Vigna radiata L.) to seed dressing and seed priming with nano molybdenum trioxide
    (Department of Agronomy, OUAT, Bhubaneswar, 2020) Nanda, Jyotirmay; Dwibedi, Sanat Kumar; Paikaray, R. K.; Behera, Basudev; Jena, Satyananda; Samant, Prasanna Kumar
    A field experiment entitled “Response of greengram (Vigna radiata L.) to seed dressing and seed priming with nano molybdenum trioxide” was undertaken during rabi 2019-2020 at Agronomy Main Research (AMR), College of Agriculture, Odisha University of Agriculture and Technology, Bhubaneswar, Odisha, India. The experiment was laid out in radomised block design (RBD) consisting of ten different treatments i.e. M0 (no seed treatment with Mo); M1 (seed dressing with Sodium molybdate @ 400 ppm); M2, M3, M4 and M5 (seed dressing with nano Molybdenum trioxide-MoO3 @ 50, 100, 200 and 400 ppm, respectively); and M6, M7, M8 and M9 (seed priming with nano MoO3 @ 50, 100, 200 and 400 ppm, respectively). The treatments were replicated thrice. Inoculation of greengram seeds cv. Shreya (IPM 2-14) with Rhizobium sps. was undertaken in all treatments as per the recommended practice, except in M0 (control). The MoO3 nanoparticles (NPs) were successfully synthesized from Ammonium molybdate through calcination at 600 0C for 5 hours (hrs) which on characterization by Transmission Electron Microscope (TEM) and X Ray Diffractometer (XRD) indicated globular shaped NPs of 68.55 nm. Hydropriming of greengram seeds that was undertaken to ascertain the best befitting duration for nanopriming indicated the maximum germination percentage (89.5%) and seedling vigour index (2,393.8) at 4 hrs. Nanopriming with MoO3 @ 200 ppm (M8) was most promising in recording significantly superior growth and yield attributing parameters and yield as well whereas Mo (control) lagged behind. Crop height number of branches longest root length shoot dry matter and root nodulation at harvest in M8 were 39.4% and 22.6%; 39.0% and 5.6%; 23.0% and 9.3%; 43.9% and 16.3%; and 73.3% and 36.5% higher than M0 (control) and M1 (farmers’ practice), respectively. Pod plant-1 and seeds plant-1 in M8 were 28.2% and 5.3%, and 28.1% and 0.8% higher than M1 and M0, respectively. However, the test weight did not differ statistically due to treatment effects. Significantly superior growth and yield attributing characters in M8 resulted in recording the highest grain and stover yield of 0.88 and 3.74 t ha-1, respectively that were 32.53% and 8.37%, and 35.5% and 14.7% higher than M0 (control) and M1 (farmers’ practice), respectively. Seed priming with nano MoO3 @ 400 ppm (M9) and seed dressing with nano MoO3 @ 400 ppm (M5) were of second and third order in recording grain and stover yield but M0 lagged behind all treatments. The highest gross return of Rs.63,310/- ha-1 and net return of Rs.29,892/- ha-1 with benefit-cost ratio of 1.89: 1 and the lowest cost of production of Rs.3,798/- t-1 of grain was estimated under M8 which was followed by M9 and M5 in reducing order. The highest crop profitability of Rs.472/- ha-1 d-1 was estimated in M8 but the lowest was in M0 (Rs.227/- ha-1 d-1).

    A STUDY ON VALUE CHAIN ANALYSIS OF CASHEW NUT IN SRIKAKULAM DISTRICT OF ANDHRA PRADESH
    (OUAT,Bhubaneswar) Mownika, Malla; Munda, Pandaba Charan
    Cashew was introduced to India around five centuries ago by the Portuguese. Earlier it was not a main crop as an agriculture bases but was used for some other purposes as soil binding to check erosion. Later on it became a high economy crop across the country. Now India became one of the leading producer and exporter of cashew across the world. It has approximately 0.97 million hectare for cashew cultivation producing approximately 770 kg cashew per hectare. It has been produced in many states across India mainly in the states of Maharashtra, Kerala and Karnataka in western coast and Andhra Pradesh, Odisha and Tamil Nadu in eastern coast. India accounts around 65 percent of world’s total export with exporting to more than 60 countries in the world.According to officials, the state government has planned to take the unused land on lease at Srikakulam and Vijayanagaram for cashew cultivation in which the cashew cultivation will be carried out under the aegis of Kerala State Cashew Development Corporation (KSCDC). The Government of A.P. is giving input subsidy of 50% to all the farmers and 75% to SC & ST farmers for its cultivation in A.P.The first cashew unit was started in Andhra Pradesh at Vetapalem. However, the growth of the cashew processing units was rapid at Palasa due to the proximity to the raw material and availability of laborin abundance at cheaper rates.This study aimed to find out how the performance of value chains in potential area at the Srikakulam District of Andhra Pradesh could be improves in order to bring sustainable development to India’s cashew industry. The key players involved in value chain of cashew nut are producers, village traders, commission agents, wholesalers, retailers, processors. The present study is intended primarily as a research initiative to serve as the basis for informed dialogue and policy development to encourage more detailed guidelines following further study and consultation. It focused on issues like.Field data were collected from sample farmers based on their demography, land holding, cropping pattern, cost of cultivation, and problems facing. Excel software is used to analyse and interpreted the data. In results and interpretations it is analysed, the general characteristics of farmers like age distribution, education, family size, annual income. And next to that, general characteristics of intermediaries like their age and education. Next to that, general characteristics of processors like their age, education, income. There is also analysis on problems faced by farmers during the production. From this study, it is found that lack of institutional support is a major constraint. And it is also revealed that majorconstraints of producers was pest attack. Need of cashew board near to the area, awareness programmes for price arrival information, and improved technology needed before production are some of the solutions for those constraints.

    Efficacy of Newer Insecticides Against Sucking Pests of Okra
    (Orissa Univesrity of Agriculture and Technology; Bhubaneswar, 2001) Acharya, Subhadra; Mishra, H. P.
    The efficacy of some newer insecticides, viz., acetamiprid, thiomethoxam, imidacloprid, NACLFMOA and abamectin was studied along with conventional pesticides like dimethoate, cypermethrin, dicofol and ethion and a plant product azadirachtin against
