    Opportunities and Challenges in the Adoption of Bio-fertilizers in Akot Tehsil of District Akola, Maharashtra
    (Swami Keshwanand Rajasthan Agricultural University, Bikaner – 334006, 2022) Sweety Kumari Choudhry; R.K Verma
    Green revolution in India brought massive gains in agricultural production. However, it did not translate into a model for sustainable agricultural growth. The increase in agricultural production under green revolution was brought mainly by the extensive use of chemical fertilizers, pesticides etc. The effect of chemicals is usually direct and fast. Moreover, the moderate price level and higher productivity made it more marketable to the farmers (Savita 2007). However, excessive dependence on chemical fertilizers with major emphasis on nitrogen and phosphorus and excessive use of pesticides has led to fall in soil fertility, water contamination, polluted water basins, destroyed micro- organisms and friendly insects and making the crop more prone to diseases and unsustainable burden on the ecosystem. It reduced the colonization of plant roots with mycorrhizae and inhibits symbiotic nitrogen fixation by rhizobia due to high nitrogen fertilization. Nutrients are easily lost from soils through fixation, leaching or gas emission leading to reduced fertilizer efficiency (Begum 2019). Under this situation, bio-fertilizers offer great potential not only for improving soil fertility but also solubilise insoluble soil phosphates and produces plant growth substances in the soil for efficient use of various resources for increasing crop production on a sustainable basis. The bio-fertilizers are bacteria, algae and fungi and may broadly be classified into two categories viz. Nitrogen fixing like Rhizobium, Azotobactor, Azospirilum, Acetobacter, Blue Green Algae and Azola and Phosphorous solubilisers/ mobilisers (PSM) and Mycorrhiza.

    Genetic Variability and G x E Interaction Studies for Agro-morphological and Physio-biochemical Traits in Mungbean [Vigna radiata (L.) Wilczek]
    (COLLEGE OF AGRICULTURE, BIKANER SWAMI KESHWANAND RAJASTHAN AGRICULTURAL UNIVERSITY, BIKANER (RAJASTHAN)-334006, 2022) ANIL KUMAR; N. K. Sharma
    Pulses are an important source of staple protein for vegetarians which constitute a major population of the country. Mungbean is also known as green gram, an ancient pulse crop widely cultivated under different agro-ecological situations in India mainly during Kharif and summer seasons. It is a diploid species having chromosome number (2n=22) belongs to family Leguminosae (Fabaceae), sub-family Papilionaceae and is botanically recognized as Vigna radiata (L.) Wilczek. Mungbean is a native of South Asia (India). Vigna radiata var. sublobata is the possible progenitor of mungbean. It is basically a self- pollinated crop (Singh et al., 2015).
