    ECONOMIC ANALYSIS OF FARMING SYSTEMS IN WESTERN MAHARASHTRA
    (MPKV, Rahuri, 2024) Shaikh Mohasin Rashid; R.B. Hile
    Farming system is a mixture of farm enterprises such as crop, livestock, apiculture, agro-forestry and fruit crops. In this system family allocates its resources. It is to efficiently manage the existing environment for the attainment of the family goal. Farming system represents proper combination of farm enterprises and the resources available to the farmer to raise them for profitability. The farming system is the combination of crops or a mix of enterprises, where the product and by product of one enterprise serve as input for another. The focus is on the system as a whole, rather than just its overall output. Thus, the present investigation was aimed to study, “Economic analysis of farming systems in Western Maharashtra”. The study investigated the resource use patterns, efficiencies, productivity, costs, returns, employment and income patterns, optimal plans, and problems associated with the selected farming systems. Primary data for the year 2018-19 was collected from 240 sample farmers in the four districts of Western Maharashtra viz. Ahmednagar, Nashik, Pune, and Sangli in Western Maharashtra region using a personal interview method with specially designed schedules. The three widely adopted farming systems were selected for the study: I) Crops only, II) Crops + Livestock, III) Crops + Livestock + Horticulture crops. The average land holding of sample farmers was found to be more in rainfed region than the irrigated region. In all farming systems, land was the major item of capital assets, while value of irrigation structures was the second major item of capital assets in both irrigated as well as rainfed region. More capital assets were found in irrigated region as compared to rainfed region because irrigated land value was higher than rainfed region due to more irrigation facility and quality of land.

    BIOLOGY AND MANAGEMENT OF PULSE BEETLE Callosobruchus chinensis IN CHICKPEA
    (MPKV, Rahuri, 2024) Sayantika Banik; R.S. Bhoge
    Callosobruchus chinensis L. is an important pest affecting different pulses in storage causing quantitative and qualitative loss. While other management methods have different side effects on the environment and human health there is a need of ecofriendly methods to manage the pests with this background the present investigation entitled “Biology and management of pulse beetle, Callosobruchus chinensis in chickpea” was conducted at the laboratory of Seed Technology Research Unit, MPKV, Rahuri during 2022-2023. In the experiment of biology of Callosobruchus chinensis on chickpea, on an average 74.33 ± 3.05 eggs were laid by a single pulse beetle female. The average incubation period of pulse beetle was 3.67 ± 0.76 days in chickpea. The larval period was varied from 20- 25 days with an average 20.33 ± 1.00 days in chickpea. The average pupal period of pulse beetle was 6± 0.85 days which range from 6 to 7 days in chickpea. The total developmental period of pulse beetle was varied from 31-34 days and average of 32± 2.06 days in chickpea. Studies on management of pulse beetle, C. chinensis using biorationals concluded that deltamethrin was a promising treatment followed by neem oil and sand for longer storage of chickpea seeds. Thus the present investigation advocated that neem oil @ 5ml/ kg seed and sea sand @ 1kg/ kg seed may be utilized as suitable ecofriendly seed protectants in stored chickpea against pulse beetle, Callosobruchus chinensis for a long period of 6 months. The current research paves the way to provide awareness to the farmers about the nature and extent of damage caused by the pulse beetle in storage chickpea.

    SEASONAL INCIDENCE AND EVALUATION OF BIOPESTICIDES AGAINST DEFOLIATOR INSECT PESTS OF LUCERNE, Medicago sativa L. IN SEED PRODUCTION PLOT
    (MPKV, Rahuri, 2024) PATIL RAVINDRA DILIP; S. A. Landge
    Among the entomopathogenic fungal and viral biopesticides tested against H. armigera and S. litura, Metarhizium rileyi (1×108 cfu/g) 1.15% WP found most superior treatment against both the pest. HaNPV @ 500 LE/ha and SlNPV @ 500 LE/ha were also effective treatments against H. armigera and S. litura respectively. As regards seed yield M. rileyi (1×108 cfu/g) 1.15% WP recorded highest seed yield (3.20 q/ha.) with ICBR 1:28.07. Whereas, the treatment with spraying Metarhizium anisopliae (1×108 cfu/g) 1.15% WP found at par with this treatment in respect of yield and recorded (3.12 q/ha) yield of seeds with ICBR 1:26.41. All the tested entomopathogenic fungal sprays, viral sprays and their combinations did not affect the activities of honey bees in the treated field of lucerne seed crop. Study on the pollinator fauna, their relative abundance in lucerne revealed that as many as 12 species of pollinators were foraging on lucerne flowers. Out of these, hymenopterans included eight species forming 83.60 percent of total pollinators. lepidopterans included three species and dipterans included two species which altogether constituted 16.40 percent of total pollinators. The most dominant pollinator was Apis florea (29.60 %) followed by A. cerena (13.60 %), A. dorsata (12.50 %) and A. melifera (8 %)
