“…This clearly indicated that Sesbania aculeata have positive influence on rice grain yield when grown as intercrop for brown manuring than without Sesbania aculeata. The results are in conformity with the findings of Hiremath et al (2019). Kumar and Ladha (2010) reported that 10% lower yield in DSR compared to TPR in India.…”

Present study was undertaken to assess the scope of Sesbania aculeata as brown manure on grain yield, partial factor productivity of nutrients as well as to cut down the nutritional requirement of direct seeded rice and transplanted rice-wheat system cropping system. Results revealed that puddled transplanted treatment having 100% NPK with Sesbania aculeata recorded highest rice grain yield (4.3 t ha‒1) which was statistically at par to dry direct seeded rice treatment having 100%, 75% and 50% NPK with Sesbania aculeata. The yield of wheat taken after puddled transplanted rice was recorded lower than the wheat grown after direct-seeded rice. System productivity, PFP, AUE, net returns and B: C ratio of DSR-wheat was higher (7.5 t ha‒1, 25 kg grain/kg nutrient applied, 3.3%, USD 870 ha‒1, 1.2) compared to puddle transplanted rice-wheat (7.4 t ha‒1, 24.5 kg grain/kg nutrient applied, 0.6 %, USD 786 ha‒1, 0.9, respectively). The highest B: C ratio (2.4) was recorded in treatment having 50% NPK of recommended dose, which was statistically at par with the treatment having 75% NPK of recommended dose. Interaction effect of nutrient application coupled with crop establishment method revealed that the highest B:C ratio (1.7) was registered also in DSR-wheat system having 75% and 50% NPK of recommended dose.

Depthwise variation in selected soil properties as influenced by tillage and residue management in sandy loam soil of North-West Himalayas, India

The present study aimed to determine the effect of varying tillage and residue management in a sandy loam soil under maize (Zea mays L.)-wheat (Triticum aestivum L.) sequence. The research was carried out at ICAR- Indian Institute of Soil and Water Conservation, Research Centre, Chandigarh, research farm, located at Panchkula, Haryana, in maize (kharif)-wheat (rabi) cropping sequence during 2009–2017. Six treatments implemented were Conventional tillage (CT); Deep tillage once in three years (DT); Conventional tillage with integrated nutrient management (CT-INM); Conventional tillage with brown manuring in maize + cowpea (1:2) and wheat + pea (4:1) ratio (CT-BM); Conservation tillage (CST) ; Conservation tillage with brown manuring (CST-BM). The compaction level attained under conservation tillage based systems were lower than the corresponding levels in the conventional tillage control. The highest percentage of macro aggregates was found in CST-BM treatment (48%), followed by CST (45%) and CT, DT and CT-INM recorded much lesser macro aggregate (29.3, 28 and 31%). Conventional tillage (CT) reduced macroaggregates with a concomitant increase in microaggregates (<0.25 mm) percentage. The mean soil moisture percentage average in surface (0–15 cm) and sub surface soil (15–30 cm) were found to be higher under DT, CST and CST-BM treatments over CT and CT-INM treatments. In general, the soil moisture was found to be proportional to the amount of biomass added under various treatments. The mean soil available nitrogen were 15.4% and 17.5% higher under CT-BM and CST-BM treatments respectively, over the control (CT).
