Background: Lentil (Lens culinaris Medik.) is an important winter pulse crop grown in Indian subcontinent. Lentil like other pulse crops is given secondary importance as far as its growing environment is concerned. It is grown on marginal lands with low fertility and receives sub-optimal fertilizer application. Rhizobium and phosphate solubilizing bacteria are known to benefit the crop by increasing the availability of soil nitrogen and phosphorus and effect of zinc solubilizing microbes in Lentil has not been studied earlier.
Methods: An experiment was conducted during Rabi 2019-20 and 2020-21 to study the effect of phosphate and zinc solubilizing microbes on growth, yield and economy of lentil at research farm area of Pulses section Dept. of Genetics & Plant Breeding, CCS HAU, Hisar. The experiment was laid out in randomized block design with eleven treatments replicated thrice.
Results: Growth as well as yield parameters were significantly affected by different treatments and were significantly higher with application of 50% recommended phosphorus dose application + 12.5 kg ZnSO4 + Biophos + Biozinc. The soil pH did not differed significantly under different treatment. The Soil EC under different treatment differed significantly with control. The soil organic carbon was found maximum in T10 and it was closely followed by T11. Similarly, maximum net return and BC ratio was obtained in T10 treatment followed by T9.
The leading lentil-producing countries are Canada, India, Australia, Türkiye, USA, Nepal, Syria, Bangladesh and China. In India, lentil is mainly cultivated in rainfed areas of Madhya Pradesh, Uttar Pradesh, West Bengal and Bihar with the national production of 1.49 million tons yielding out of 1.46 million hectares area (INDIASTAT 2021). Although lentil has seen a rise in productivity in the last few years, this increase is not encouraging and has started to stagnate.
India has to lift up pulse productivity with its limited and decreasing land holding to assure food and nutritional security. Sustainable soil nutrient management is one of the ways to increase the pulse production and productivity. The yield level of lentil is generally low because it is less cared crop and mostly grown in poor soil without manures and fertilizers. Regular depletion of nutrient resources of soil has led to emergence of several nutrient deficiencies in many crops including lentil. As a leguminous crop, it utilizes atmospheric nitrogen to meet its partial nitrogen requirement and thus occupies an important place in crop rotation in different part of the country. It is the most suitable crop for rainfed conditions, because of its deep root system and capability to stand in drought condition. In comparison to any other rabi crops of similar condition, except gram, it is greatly esteemed for its ability to give satisfactory yield even under sub-optimum condition and less rainfall in winter season.
Biofertilizers are gaining importance as they are ecofriendly, non-hazardous and non-toxic. A substantial number of bacterial species, mostly those associated with the plant rhizosphere, may exert a beneficial effect upon plant growth. Biofertilizers include mainly the nitrogen fixing, phosphate solubilizing and plant growth promoting micro-organism. Inoculating pulse crops with rhizobia to add nitrogen is routine for most growers. The presence of efficient and specific strains of Rhizobium in the rhizosphere is one of the most important requirements for proper establishment and growth of grain legume plant. Phosphate solubilizing bacteria partly solubilizes inorganic and insoluble phosphate and improves applied phosphorus use efficiency stimulating plant growth by providing hormone, vitamin and other growth promoting substances (Gyaneshwar et al., 2002). Zinc (Zn) is required for the metabolism of plants, enzyme function and ion transport. Consequently, inadequate Zn availability in soil is a main consideration for plant nutrition, resulting in a significant loss in production and grain nutrient content.
