Abstract - A laboratory experiment was conducted to
major vegetable crop where indigenous pulses are also preferred. French bean is consumed as immature tender fruits, green grains as vegetables and dry grain (Rajmash). The nutritive value of 100 g of green pod contains 1.7 g protein, 0.1 g fat, 4.5 g carbohydrate, 1.8 g fibre and is also rich in minerals and vitamins. It is popularly grown in Punjab, Harayana, Jammu and Kashmir, Himachal Pradesh, Western Uttar Pradesh, Maharashtra, Karnataka, Andhra Pradesh and Tamil Nadu states of our country. As French bean is major crop in Rabi season, the seeds are to be produced during Rabi and used for sowing during next season or year.
The results revealed that, among different seed treatments, seed treated with deltamethrin, neem oil, castor oil, karanj oil found to be effective over control. The French bean seeds treated with Deltamethrin, neem oil significantly recorded lower moisture content (7.30%, 7.34%), higher germination (76.67%, 75.33%), higher speed of germination(19.42, 19.28), root length (11.59, 11.43 cm), shoot length (7.65, 7.59 cm), vigour index-I (1475,1432), vigour index-II (1606, 1572), seedling dry weight (20.95, 20.87 mg), lower electrical conductivity (1.86, 1.91dS m-1) and test weight (33.60, 33.51g),respectively. While, control seed recorded higher moisture content (7.69%), lower germination (64.33%), root length (9.46 cm), shoot length (6.58 cm), vigour index-I (1032), vigour index-II (1193), seedling dry weight (18.54 mg), higher electrical conductivity (2.27 dS m-1) and test weight (31.90g), at the end of 300 days of storage period. From present investigation it was clear that seed treated with organic and inorganic seed treatment i.e. deltamethrin (T9) and neem oil (T2) protected its quality while, control seed deteriorated at the end of storage period.
Botanicals have been used from a very long time by many farmers in the world from decades to control stored insect pest (Araya and Emana, 2009). Many scientists revealed that use of botanicals as pre storage seed treatment is effective in management of storage pest and thus helps in improving quality of seed. Botanicals viz., neem leaf powder, neem oil, karanj oil, castor oil, vekhand powder, citronella oil, turmeric powder, ash etc were used.
investigate the “effect of organic and inorganic seed treatments on seed quality of French bean (phaseolus vulgaris L.)”. The seeds of French bean was subjected to different treatments viz., T0: Control (untreated), T1: Neem leaf powder @5g/kg of seed, T2: neem oil @5ml/kg of seed, T3: Castor oil @5ml/kg of seed, T4: karanj oil @5ml/kg of seed, T5: vekhand powder @10g/kg of seed, T6: Termuric powder @5g/kg of seed, T7: Citronella oil @5ml/kg of seed, T8: Ash @5g/kg of seeds, T9: Deltamethrin @0.04ml/kg of seed. Observations were taken to know the seed quality of French bean seed at regular intervals.
In storage, viability and vigour of the seeds is regulated by many physico-chemical factors like moisture content of the seed, atmospheric relative humidity, temperature and initial seed quality, physical and chemical composition of seed, gaseous exchange, storage structure, storage insects and packaging materials. Hence, storage of seed till next planting time assumes prime importance for successful seed production programme.

A comprehensive laboratory study on “Effect of organic and inorganic seed treatments on seed quality of French bean (Phaseolus vulgaris)” was under taken at Seed Technology Research Unit, Mahatma Phule Krishi Vidyapeeth, Rahuri. Dist. Ahmednagar (MS) during May, 2019 to Feb, 2020. The material for present study consists of freshly harvested seeds of French bean variety Varun obtained from Botany Farm, College of Agriculture, Pune. The experiment was laid out in Completely Randomized Design (CRD) with three replications. HDPE (High Density Polythene Bags) were used as a container for the experiment. The seeds of French bean was subjected to ten different treatments viz., control (T0), neem leaf powder

INTRODUCTION
Pulses occupy a very important position in Indian diet. They are important source of protein and calories. On an average, pulses contain 22 to 24 per cent protein as against 8 to 10 per cent in cereals. A good amount of lysine is present in the pulses. French bean (Phaseolus vulgaris L.) belongs to the family Leguminoceae and it is native of South America. In India and most of the tropical Asia it is a
