Almost all the growth and yield attributes such as plant height at Indian bean, 60 DAS and at harvest, number of branches per plant at 60 DAS and at harvest, dry matter Nutrient accumulation per plant at 60 DAS and at harvest, number of inflorescences per plant, management, Biocompost, number of pods per plant, number of seeds per pod, length of pod and 100 seed weight at Growth and yield harvest were recorded significantly higher with application of 125% RDF through attributes, Seed inorganic fertilizer over 100% RDF. Similarly, seed (728kg/ha) and stover yield (1484 yield, Economics kg/ha) of crop were also noted significantly higher with application of 125% RDF than 100% RDF. An application of 2 t/ha biocompost resulted in significantly higher seed yield Article Info and stover yield(727 kg/ha and1490 kg/ha, respectively) over other treatments because of significant enhancement in growth and yield attributes under the same treatment(2 t/ha Accepted: 20 February 2019 biocompost).Foliar application of 1% banana pseudostem enrich sap to Indian bean at 30 Available Online: and 60 DAS was resulted in significantly higher growth and yield attributes over without 10 March 2019 foliar spray (control),ultimately resulted in significantly higher seed and stover yield of Indian bean as well as higher economic returns. Introduction field crop in Tamil Nadu, Andhra Pradesh, Karnataka, Madhya Pradesh and Maharashtra. Indian bean (Lablab purpureus L.) also The Indian bean belongs to the family known as field bean or dolichos bean, is Leguminosae and considered as nutritious grown throughout tropical regions of Asia, vegetables as they contain high amount of Africa and America. In India, it is grown as a vegetable protein, besides carbohydrates and 2443 Int.J.Curr.Microbiol.App.Sci (2019) 8(3): 2443-2450 vitamins. In south Gujarat, Indian bean is under south Gujarat condition, hence, the most important crop grown particularly in present study is proposed. Navsari, Surat and Valsad districts. It is mostly grown during rabi season in field Materials and Methods vacated by kharif crops like paddy. A new variety GNIB -21 found most promising for Field experiment was conducted on plot no. vegetable purpose due to it’s short stature D-17 at College Farm, N.M. College of plants, early picking and short maturity. It Agriculture, Navsari Agricultural University, became popular among the farmer of south Navsari, during rabi season of 2015-16. Gujarat due to it’s suitability as intercrop also. Navsari Agricultural University is Now days, use of chemical fertilizer is geographically located at 20° 57' N latitude increasing to boost up crop production. and 72° 54' E longitude with an altitude of 10 Simultaneously, cost of chemical fertilizer is meters above the mean sea level. Navsari is increased constantly, besides these, only use located in south Gujarat heavy rainfall zone-I of inorganic fertilizer is injurious to soil (Agro-ecological situation-III). The climate of health and soil productivity. Integration of this zone is typically sub-tropical, inorganic, organic and bio-fertilizer play vital characterized by humid and warm monsoon role for enhancing crop productivity and with heavy rains, quite cold winter and fairly sustaining soil fertility, this proves great hot summer. The average annual rainfall of promise for farmer. Thus the basic concept this tract is about 1440 mm. The soil of underlying the principles of integrated experimental field was clayey in texture nutrient management is the maintenance and having medium to poor drainage, EC 0.36 possible improvement in soil fertility for dS/m and soil pH 7.80. The soil is medium in sustained crop productivity on long term basis organic carbon (0.53%), low in available (Harisudan et al., 2009). Foliar application of nitrogen (197.26 kg/ha), medium in available fertilizers for increasing and exploiting phosphorus (30.93 kg/ha) and fairly rich in genetic potential of the crop is considered as available potassium (369.80 kg/ha).Total an efficient and economic method of twelve treatment combinations consisting of supplementing the nutrient requirement. two levels of inorganic fertilizer viz., F1 Application of inorganic spray will also (100% RDF) and F2 (125% RDF), three types enhances play a pivotal role in increasing the of organic manure viz., O1 (2 t/ha FYM), O2 seed yield in pulses (Chandrasekhar and (2 t/ha Biocompost) and O3 (2 t/ha Bangarusamy, 2003). Foliar application of Vermicompost) and two levels of foliar spray major nutrients like NPK was found to be viz., S1 (Without spray) and S2 (1% Banana more advantageous than soil application and pseudostem enrich sap spray at 30 and 60 also avoiding the depletion of these nutrients DAS) were evaluated in randomized block in leaves, thereby resulting in to an increased design with factorial concept with three photosynthetic rate, better nutrients replications. Indian bean variety GNIB-21 translocation is credited with the advantage of was used as a test crop and sown at a distance quick and efficient utilization of nutrients, of 45 cm × 20 cm. The experimental plot was elimination of losses through leaching and manure as per treatment with inorganic fixation and helps in regulating the uptake of fertilizer and organic manure before sowing nutrients by plants (Manomani and Srimathi, of crop. Required quantity of FYM, 2009). A judicious combination of chemical biocompost and vermicompost as well as fertilizer and organic fertilizer should be inorganic fertilizer in the form of urea and formulated for Indian bean variety GNIB-21 DAP (Diammonium phosphate) were 2444 Int.J.Curr.Microbiol.App.Sci (2019) 8(3): 2443-2450 calculated and manually applied in opened of organic matter in soil not only improved furrows as per treatment before sowing. Gap the physical properties of soil but also filling and thinning were done when enhance the microbial activity which reflected necessary and harvesting was done when crop in the possible increases of nutrient status of was full matured. Irrigations, plant protection soil ultimately it improved the growth of crop. and other practices were followed as per These results are in close conformity with the recommendation for this region for healthy findings of Chaudhari et al., (2016) and Patel crop growth. Economics of treatments were et al., (2016) in greengram. Foliar spray of computed on the basis of prevailing market 1% banana pseudostem enrich sap at 30 and price of inputs and outputs in Indian rupees 60 DAS was resulted in the highest plant under each treatment. The total cost of height, number of branches per plant and dry cultivation was calculated on the basis of matter accumulation per plant at 60 DAS and different operations performed and materials at harvest over without spray. The foliar spray used for raising crop. Statistical analysis of of organic supplies the adequate amount of the data as per the standard analysis of nutrients to plant at peak growth stage of variance technique for the experimental crop. Further foliar application of organic design and treatment means were compared at facilitate the easily absorption of nutrient P=0.05 level of probability using t-test and resulted in improvement of plant growth. calculating CD value. Results are in accordance with that of Patil and Gunjal (2011) in green gram and Patil et Results and Discussion al., (2012) in chickpea. Growth characters Yield attributes and yield Inorganic fertilizer, organic manure and foliar The various yields attributes like number of spray had significant influenced on growth inflorescences per plant, number of pods per characters (Table 1). The various growth plant, number of seeds per pod, length of pod, attributes like plant height, number of and 100 seed weight as well as seed yield and branches per plant and dry matter stover yield were influenced significantly due accumulation per plant recorded at 60 DAS to application of various levels of inorganic and at harvest were significantly higher with fertilizer, types of organic manures and levels application of 125% RDF as compared to of foliar spray (Table 2). The highest number application of 100% RDF. Zahida et al., of inflorescences per plant, number of pods (2016) also reported beneficial effect of 125% per plant, number of seeds per pod, length of RDF in French bean for growth attributes. pod and 100 seed weight were noted under Further data presented in Table 1 revealed the application of 125% RDF than100% RDF. that significantly higher plant height, number Similarly, an application of 125% RDF of branches per plant as well as dry matter produced significantly higher seed (728.78 accumulation per plant at 60 DAS and at kg/ha) and stover yield (1484.15 kg/ha) which harvest were recorded under application of 2 was to the tune of 14.86 and 13.43 per cent t/ha biocompost being at par with application higher, respectively than that of due to of 2 t/ha vermicompost over application of 2 application of100% RDF.
