Abstract
A field experiment entitled “Effect of fertilizer doses, organic manure and biofertilizers on yield and economics of urdbean (Vigna mungo L.)” was conducted during kharif season of 2017 at the Research cum Instructional Farm, under All India Coordinated Research Project on MULLaRP, Department of Agronomy, College of Agriculture, I.G.K.V. Raipur, Chhattisgarh. The soil of the experimental field was Vertisols with low, medium and high in available N, P and K, respectively and neutral in reaction. The climate of the region is sub-humid to semi-arid. The urdbean variety Indira urd Pratham was sown on 18th July, 2017 using experimental techniques of factorial randomized block design with three replications and sixteen treatments. The treatment consisted of three levels of fertilizer doses viz. 75 % RDF (F1), 100 %RDF (F2), 125% RDF(F3) and 150% RDF(F4) , two levels of organic manure (FYM) viz. control (M1-0) , 5 t ha-1( M2-5), and two levels of biofertilizer viz. LMn-16(B1), rhizobium (B2). Recommended agronomic practices were followed for raising uedbean. The crop was harvested on 19th October, 2017.
Different agro input management practices had significant effect on growth, yield attributes and yield of urdbean. However, Biofertilizer did not give significant influence on growth, yield attributes, yield and economics. Whereas, application of Fertilizer doses 125%RDF followed by 100%RDF showed significantly higher growth parameters viz. plant height (41.30, 41.00), primary branches (7.0, 6.7), nodules no.(36.17, 36.09), dry matter accumulation (10.00, 9.96), yield attributes viz. pods plant-1 (24.68, 24.62), seed yield (831.05, 829.49) and stover yield (1578.75, 1573.17), respectively. The uptake of N, P and K in seed and stover were also observed significantly higher in the above treatments viz. (26.91,6.22) , (3.58,4.31) and (5.67,17.65 kg ha-1), respectively.
In case of organic manure, application of 5 t FYM ha-1 produced significantly higher growth parameters via. plant height (42.40), primary branches (7.1), nodules no.(99.38), dry matter accumulation (10.53), yield attributes viz. pods plant-1(26.63), 100 seed weight (4.26), seed yield (885.68) and stover yield (1681.63). The uptake of N, P and K in seed and stover were also observed significantly higher in the above treatment viz. (28.98,6.87), (4.00,4.87) and (5.99,17.80) kgha-1, respectively. Interaction among fertilizer doses 100%RDF with organic manure 5t FYM ha-1 exhibited higher net return and return Re-1 invested , but it was at par to 75% RDF with 5 t FYM ha-1 for both the parameters and 125%RDF with 5 t FYM ha-1 for net return.
