“…Higher cotton yield with conjunctive application of FYM and gliricidia green leaf manure may be due to balanced supply of nutrients to the crop throughout the crop growth period. These results are in conformity with the findings of Joga Rao et al (2017).…”

A field experiment was conducted during kharif season of 2020 at research field of AICRP for Dryland Agriculture, Dr. Panjabrao Deshmukh Krishi Vid¬¬¬¬yapeeth, Akola, (Maharashtra) to study the effect of organic sources of nutrients on soil fertility and yield of rainfed cotton(Gossypiumspp.) in Vertisols. The experiment was laid out in randomized block design with three replications and nine treatments. The results revealed that, there was a reduction in bulk density, pH and electrical conductivity and an increase in hydraulic conductivity and organic carbon content with application of 50% N through FYM + 50% N through gliricidia green leaves. This treatment also resulted in significantly higher available N (193.2 kg ha-1) and K (331.1 kg ha-1) content whereas available P (15.98 kg ha-1) content was higher with application of 50% N through FYM + 50% N through vermicompost. Improvement in the seed and stalk yield of cotton was observed with application of 50% N through FYM + 50% N through gliricidia green leaves. Seed and stalk yield was increased by 8.9% and 7.7% with application of 50% N through FYM + 50% N through gliricidia green leaves as compared to inorganic treatment, respectively. The minimum seed (540.9 kg ha-1) and stalk (997.2 kg ha-1) yield were recorded with application of 12 t FYM ha-1.

“…Soil available potassium content was ranged from 72 to 162 and 77 to 163kg ha -1 at 0-15 cm, 15-30 cm with mean values of 100 and 107 kg ha -1 , respectively. According to Rao et al [24], data indicated that maximum of the soil samples were falling under low category (<141 kg ha -1 ) it may be due to lower amount of organic matter or due to the absence of potash bearing minerals (muscovite, biotite and feldspar). Similar result was reported by It is reported that highest [25] content of potassium found in surface soil than in sub surface soil.…”

The present study was undertaken to assess the soil fertility status of the soils of KVK Muzaffarnagar. Soil samples were collected from two depths viz., 0-15 cm and 15-30 cm and analysed for various soil properties. Results revealed that soils were sandy loam in texture, neutral to slightly alkaline in reaction, non-saline and low in soil organic carbon content. Mean values of CEC, SOC, available nitrogen, available phosphorus, available potassium and available sulphur were 11.22 and 9.62 C mol (p+) kg-1, 0.17 and 0.13 g kg-1, 260.16 and 208.14 kg ha-1, 30.86 and 27.30 kg ha-1, 100.94 and 107.89 kg ha-1 and 13.51 and 12.84 kg ha-1 recorded at 0-15cm and 15-30 cm depth, respectively. The mean of DTPA extractable zinc, DTPA extractable iron, DTPA extractable manganese and DTPA extractable copper were 0.28 and 0.31 mg kg-1, 0.97 and 1.22 mg kg-1, 2.14 and 1.78 mg kg-1 and 0.23 and 0.19 mg kg-1 recorded surface and sub-surface depths, respectively. Soils are low in available nitrogen and potassium and medium in available phosphorus status. Cationic micronutrients such as iron, copper and zinc contents were found deficient in range, whereas manganese content was found to be sufficient.

“…Improved yield under conjunctive use of nutrients could be ascribed to the favorable soil physicchemical properties that favored slow and steady supply of the nutrients by the nutrient needs of the cotton crop coinciding with the critical stages apart from reduced losses of nutrients, common under inorganic fertilization [14]. At all the crop growth stages, significant differences were observed in terms of weed density due to integrated nutrient management practices.…”

A field investigation was conducted to evaluate the effect of moisture conservation practices [flat bed sowing, ridge and furrow, broad bed and furrow (BBF) and poly mulch on BBF] and integrated nutrient management treatments [Farmer’s practice, 100% recommended dose of fertilizers (RDF) of 150:60:60 NPK kg ha-1, 125% RDF, 100% RDF along with 25% N through Farm Yard Manure (FYM) or press mud] and their combined effect on weed dynamics of Bt cotton at College Farm, Professor Jayashankar Telangana State Agricultural University (PJTSAU), Telangana, India. The experiment was laid out in strip-plot design and replicated thrice. Pooled data of the two years (2015 and 2016) indicated that poly mulch on broad bed (M4) registered significantly lower weed density and dry weight at 30 days after sowing (DAS) and it was followed by broad bed and furrow (M3) which was at par with flat bed (M1) and ridge and furrow (M2) methods. Among nutrient management practices, lower weed density was recorded with the application of 100% RDF (S2) followed by 125% RDF (S3) and 100% RDF (S5) along with pressmud equivalent to 25% RDN (S5). However, the interaction effect on weed density and drymatter was found to be non-significant at 30 DAS. Contrary to this, at 60 and 90 DAS, the interaction was found to be significant. At 60 DAS, poly mulch on broad bed (M4S2) along with 100% RDF and poly mulch on broad bed (M4S3) along with 125% RDF recorded lower weed density over other treatment combinations. At 90 DAS also similar results were observed with respect to weed density. However, lower weed dry weight was observed with poly mulch on broad bed (M4S3) along with 125% RDF.
