Effect of Soybean Crop Residue Incorporation, Biofertilizers on Nutrient Uptake, Yield of Chickpea (Cicer arietinum L.)

Abstract

The investigation was laid out on clay loam soil at Agricultural Research Station, Adilabad during rabi, 2020 with the aim to understand the chickpea crop performance with residue incorporation and use of biofertilizers along with varied NP recommended doses (0,50,75 and 100%). Results, revealed that, i.e., application of fertilizers i.e., 20:50:20 kg ha-1 N: P2O5:K2O recorded significantly higher grain yield (2558 kg ha-1) and stover yield (3255 kg ha-1) among all the treatments. Significantly superior nitrogen content (3.49 %), P content (0.53%), K content (1.62 %) and S content (0.34 %) by grain were observed with full dose of NPK application. Nutrient uptake of N (104.47 kg ha-1), P (15.29 kg ha-1), K (47.95 kg ha-1) and S (10.13 kg ha-1) by grain at harvest.

Effect of Bio-Stimulant (Plant Probiotics) on Growth, Yield and Microbial Activity of Chickpea (Cicer arietinum L.) Grown in Vertisol of Chhattisgarh

“…However, treatment T2 (100% RDF) accumulated highest K in grain with a mean value of 0.60%, which was only treatment found ignificantly superior over control. Similar findings was reported by Dhegavath et al [36]. Nitrogen and potassium content in stover did not differ significantly by the application of bio-stimulants, as well as by chemical fertilization.…”

“…Highest stover yield (1342.27 kg ha -1 ) was recorded in treatment T2 where 100% RDF was applied, followed by treatment T7 (1087.33 kg ha -1 ) where 50% RDF was applied along with bio-stimulants at 1:200 dilution level. Similar findings was also observed by Dhegavath et al [36]. Population of bacteria in rhizosphere soil was analysed at 45 and 60 days after sowing.…”

“…Nitrogen content in grain not affected significantly by bio-stimulants application (Table 3). In case of phosphorus content, highest phosphorus content was associated with treatment T7 (Bio-stimulants at 1:200 dilution with 50% RDF) with a mean value of 0.58 %, followed by treatment T2 (RDF) with a mean value of 0.56% Similar findings was reported by Dhegavath et al [36], Varma et al [39]. Potassium content in grain varied among treatments.…”

Effect of Integrated Nutrient Management Practices on Growth and Yield of Chickpea under Different Chickpea-Based Cropping Systems in Western Rajasthan, India

“…Vasanthi and Subramanian [8] observed that the highest grain yield and crude protein N, P, and K concentrations and uptake were recorded with the application of vermicompost at 2 t ha -1 along with 100 percent recommended levels of N, P, and K. Mahetele et al [9] reported that the addition of FYM at 10 t ha -1 to soil improved the supply of plant-available nutrients and brought about a favorable soil environment, which ultimately increased the nutrient and water holding capacity of the soil for a longer period and improved the plant dry matter. Similarly, Dhegavath et al [10] reported that all growth parameters, that is, plant population, plant height, dry matter production, total number of pods, test weight, seed yield, stover yield, and harvest index, were significantly higher under soybean residue incorporation with the treatment that received 100% RDF. However, it was found on par to treatment of 75% RD of N plus biofertilizers and 75% RD of P plus biofertilizers along with 50% RD of N plus biofertilizers and 75% RD of P plus biofertilizers.…”
