Abstract	A field experiment was conducted during rainy (kharif) seasons of 2020 and 2021 at the research farm of ICAR- Indian Agricultural Research Institute, New Delhi to evaluate the performance of pigeonpea [Cajanus cajan (L.) Millsp] as affected by enriched organic formulations. The experiment comprised of seven nutrient sources, viz. control; 100% RDN through FYM; 100% RDN through improved RRC (Rice Residue Compost); 100% RDN through PHA (Paddy Husk Ash) enriched FYM; 75% RDN through PHA enriched FYM; 100% RDN through PPC (Potato Peel Compost) enriched FYM; and 75% RDN through PPC enriched FYM that were tested in randomized block design and replicated thrice. Significantly higher number of pods per plant was observed with the application of 100% RDN through PHA enriched FYM over control during both the years of study. The same treatment resulted into statistically higher yields of seed (1.89; 1.97 t/ha) and stover (7.83; 8.03 t/ha) over control and remained at par with 100% RDN through PPC enriched FYM and FYM during both the years. Results further indicated that highest gross returns, net returns and net B:C ratio (₹121.2 × 103 and 131.9 × 103/ha; ₹94.9 × 103 and 104.6 × 103/ha; 3.60 and 3.84) were obtained with 100% RDN through PHA enriched FYM over control and remain at par with treatment 100% RDN through PPC enriched FYM and FYM. Significantly maximum amount of available N in soil after harvest of pigeonpea crop was obtained under application of 100% RDN through PPC enriched FYM (229.1 and 231.9 kg/ha) over control. Further, application of 100% RDN through RRC showed superiority in increasing the available K (264.9 and 265.0 kg/ha) content in soil over control and other nutrient sources during both the years.

Abstract	Farmer' Participatory On Farm Trials (FP-OFT) were conducted at 10 different locations in Chandauli district of Uttar Pradesh during rabi 2016-17 in medium black soils to study the influence of soil test crop response (STCR) approach vis-a-vis farmers' practice on productivity and economics of chickpea (Cicer arietinum L.). Result revealed that targeted seed yield of chickpea (16 q/ha) was achieved by adoption of STCR approach. The mean grain and stover yields of chickpea under STCR were increased by 37.1% and 41.2%, respectively over the farmers' practice (FP). The plant height, number of root nodules, pods/plant and test weight of seed were also increased by 11.6, 29.3, 11.6 and 26.0% respectively, over the FP. There was much larger negative balance in available nitrogen and available potassium status under farmers' practice compared to STCR based nutrient management approach. The gross return, net returns and benefit-cost ratio (BCR) under the STCR approach were between ` 70200-77450/ha, ` 48019-55176/ ha and 2.16-2.48 which were higher as compared to farmers' practice across the different locations. STCR based nutrient management approach should be adopted by the farmers for getting higher crop productivity and profitability and improving soil fertility status.

Abstract	Integrated nutrient management prescription was developed for late-sown variety of wheat (Triticum aestivum L.) (HD 3059) through soil test based crop response study. A field experiment was conducted at the research farm of ICAR-Indian Agricultural Research Institute, New Delhi during winter (rabi) season of 2020–21 and 2021–22 to develop the integrated nutrient management prescription for late-sown wheat. Experiment was laid out in factorial randomized block design with 24 treatments having 3 levels of each N (60,120,180 kg/ha), P2O5 (30, 60, 90 kg/ha) and K2O (20, 40, 60 kg/ha). The basic parameters, viz. nutrient requirement (NR), percentage contribution of nutrients from soil (CS); fertilizer (CF) and farmyard manure (FYM) (CFYM) were quantified. Fertilizer prescription equations in integration with FYM were developed from the data obtained in the study. In order to produce 100 kg of late-sown wheat, the amount of major nutrients needed were 2.24 and 2.27, 0.45 and 0.47, 1.89 and 1.92 kg of nitrogen (N), phosphorus (P) and potassium (K) during 2020–21 and 2021–22, respectively. Phosphorus as soil nutrient contributed the maximum towards crop production; while the contribution of K from fertilizer (118.38 and 125.03) was highest for both seasons. Contribution of N from fertilizer (50.05, 51.38) was more than that of soil (33.81, 33.65). However, contribution of all the nutrients from FYM was lower. The equations developed were used to formulate ready reckoner for a range of soil test values to get a yield target of 55 q/ha for late-sown wheat. Nutrient management of late-sown wheat involving inorganic fertilizer in integration with FYM (10 t/ha) was prescribed through the ready reckoner. The study suggests that the excessive amount of fertilizer consumption as well as the subsequent adverse effect on the environment can be curtailed if FYM is used in combination with inorganic fertilizer.

Abstract	A field experiment was conducted to study the comparative influence of microbial preparations ,viz. phosphate solubilizing fungi (Jumpstart 2.0), phosphate solubilizing bacteria (PSB), Arbuscular mycorrhiza fungi and humic acid formulation (Bolt GR), in different combinations on soil microbial population and properties (Alkaline phosphatase, dehydrogenase, FDA hydrolytic activity, soil microbial biomass). Bacteria dominated the microbial population, with initial cfu level of 1.73 Ã— 107 to a maximum of 6.2 Ã— 107 gm-1 soil on 90 days after sowing (DAS) in plot, where PSB was applied @ 500 g/ ha, while plots with Jumpstart 2.0 application (@1.65 ml/ kg seed) recorded higher fungal population (7.4 Ã— 106 cfu/g). Treatments and crop age had significant impact on microbial population and their interaction was also found to be significant. Soil microbial properties also increased significantly with crop aging and reached to a higher level on 90 DAS for all the treatments. Microbial activity was invariably found to be highest in T7 treatment (application of PSF @ 0.83 ml/kg seed with humic acid @ 10 kg/ha), and lowest in control plots irrespective of sampling intervals. Results concluded that application of PSF, PSB, AM Fungi and organic formulations in different combination had favourably influenced the microbial properties of soil.

Abstract	The knowledge of different sulphur (S) forms and their relationship with soil properties is of much relevance in assessing the short- and long-term availability of the nutrients to crops and in formulating sound fertilizer recommendations. For this purpose one hundred and one representative soil samples were collected from the study area and analyzed for various physicochemical properties and forms of sulphur (water soluble, exchangeable, available, organic, non-sulphate and total S) using standard methods. The different forms of sulphur viz., water soluble, exchangeable, available, organic, non-sulphate and total sulphur ranged from 1.1 to 7.0, 1.9 to 10.9, 3.1 to 21.1, 75.9 to 316.1, 8.0 to 41.5 and 75.5 to 372.5 mg kg-1, respectively in soils of Outer Himalayas under different land uses. The content of different forms of sulphur present in these soils were in the order of total sulphur, organic sulphur, non-sulphate sulphur, available sulphur, exchangeable sulphur and water soluble sulphur. All the forms of S correlated positively and significantly with organic carbon and clay content of soils. A negative and significant relationship was also observed between all forms of sulphur and sand content of soils. In the present study, it was also found that all forms of S present in soils were significantly and positively correlated with each other. The knowledge regarding different forms of S in soils and their availability controlled by different soil properties will be helpful for its management to optimize crop yields in the Outer Himalayas of Himachal Pradesh.

Abstract	The current investigation was conducted to study the fractions of sulphur in nine districts of low and mid hills of Himachal Pradesh. For this purpose 31 representative soil sampling sites were selected from nine districts and the soil samples were analyzed for physicochemical properties and different fractions of sulphur (water soluble sulphur, exchangeable sulphur, available sulphur, non-sulphate sulphur, organic sulphur and total sulphur). The results indicated that the total sulphur in soils varied from 98.2 to 470.1 mg kg-1 in surface soil (0-15 cm) and 67.2 to 370.7 mg kg-1 in sub-surface layer (15-60 cm). The organic sulphur varied from 80.5 to 401.1 mg kg-1 in surface and 44 to 306.1 mg kg-1 in sub-surface layer. The water soluble sulphur, exchangeable sulphur, available sulphur and non-sulphate sulphur varied from 1.7 to 9.2, 2.7 to 18.4, 4.5 to 27.6 and 10.2 to 58.9 mg kg-1 respectively in surface soil and 0.5 to 5.4, 1 to 17.7, 3.7 to 23.5 and 12.5 to 50.2 mg kg-1, respectively in sub-surface soil. It was observed during course of study that with increase in the soil depth the content of different fractions of sulphur decreased. These soils had the major part of their total sulphur content in organic form followed by non-sulphate sulphur, available sulphur, exchangeable sulphur and water soluble sulphur. It can be concluded that the soil texture and organic carbon content played a major role in determining the quantity of different fractions of sulphur in these soils.

Abstract	A field experiment was conducted during rainy (kharif) seasons of 2020 and 2021 at the research farm of ICAR-Indian Agricultural Research Institute, New Delhi to study the effect of nutrient and weed management on crop productivity and soil microbial properties in aerobic rice (Oryza sativa L.). Experiment was conducted in factorial randomized complete block design and replicated thrice. Nutrient management factor comprised 3 levels, viz. Control, 100% and 75% RDF + Biofertilizer (BF) consortia; and weed management factor comprised 5 levels, viz. Weedy check, Pyrazosulfuran + Bispyribac + Almix, Bispyribac + mulch, Sesbania + hand weeding (HW) and weed free check. Significantly higher plant growth and grain yield (4.2 and 4.4 t/ha) and biological yield (11.6 and 11.6 t/ha) of rice were recorded with 100% RDF but these parameters were at par with 75% RDF+ BF consortia. However, soil microbial biomass carbon, nitrogen as well as soil microbial biomass phosphorus were recorded significantly higher with 75% RDF + BF. In weed management treatments significantly higher plant height, no. of tillers, grain yield and biological yield were recorded under weed free check over weedy check and Sesbania + HW but these were recorded at par with Pyrazosulfuran + Bispyribac + almix and Bispyribac + mulch. Soil microbial biomass was significantly higher with Sesbania + HW over weedy check, Pyrazosulfuran + Bispyribac + Almix and weed free check but were at par with Bispyribac + mulch. Hence, 75 % RDF + Biofertilizer consortia along with weed management through Bispyribac at 25 DAS + organic mulch (3 t/ha) may be recommended for enhancing crop productivity and soil microbial properties in aerobic rice.

Abstract	A field experiment was conducted during rainy (kharif) and winter (rabi) seasons 2019–20 and 2020–21 at the research farm of ICAR-Indian Agricultural Research Institute, New Delhi to study the effect of rice establishment techniques (RETs) and microbial consortia mediated in situ rice residue management options on nitrogen (N) budgeting in a rice (Oryza sativa L.)-wheat (Triticum aestivum L.) cropping system (RWCS). The experiment was laid out in split plot design with 3 replications having 2 main plot treatments, viz. aerobic rice (AR) and conventional transplanted rice (CTR) in kharif and 7 sub plot treatments, viz. clean cultivation (removal of paddy straw), paddy straw incorporation, paddy straw mulching, paddy straw incorporation + Pusa decomposer, paddy straw mulching + Pusa decomposer, paddy straw incorporation + urea @20 kg/ha, paddy straw incorporation + Pusa decomposer + urea @10 kg/ha. The residual effects of these treatments were observed in seed drill and zero till sown wheat in rabi seasons. Results showed that N uptake (95.1 kg/ha and 100.4 kg/ha in CTR and 79.4 kg/ha and 83.8 kg/ha in AR) was significantly superior in CTR than AR in kharif seasons. The residual effects of in situ rice residue management options in wheat, paddy straw incorporation + Pusa decomposer + urea @10 kg/ha resulted in significantly higher N uptake (136.4 and 141.5 kg/ha) than other treatments, and it was followed by paddy straw incorporation + Pusa decomposer in both the years. The nutrient uptake by the RWCS was an important indicator of soil fertility and plant nutrient status. This investigation concluded that there is need for use of microbial consortia mediated in situ rice residue management in RWCS for positive N balance in spite of enhanced nutrient uptake.
