Burning of crop residues results in immense loss to soil fertility, in addition to this burning causes greenhouse gas emissions into atmosphere thereby disturbs the environment. A Field experiment was conducted to ascertain the crop residue and fertilizer management practices on yield and nutrient uptake of mustard at Regional Agricultural Research Station (RARS), Polasa, Jagtial situated in Northern Telangana Zone of Telangana State during rabi, 2020-21. Grain yield, nutrient content and nutrient uptake were significantly influenced by crop residue and fertilizer management practices. Highest grain and stover yield of 1194 and 2654 kg ha-1 were recorded, when 20 % excess nitrogen was applied than RDN along with residue incorporation. Nutrient uptake was significantly higher in burning treatment during initial stages of crop growth later more uptakes were observed in residue incorporation treatments. Among the treatments lowest yields and nutrient contents (N and P) were recorded in residue burning treatments. This study concluded that, instead of burning, paddy straw was to be incorporated along with 20% excess nitrogen to obtain better yields and nutrients uptake in succeding mustard crop.

“…Decomposition rates on areas that received N-rich organic residues have been studied, however, previous studies have concerned only compost. Other studies have shown a strong influence of N-rich organic residues than organic residues with recalcitrant-rich compounds [60,61]. Similarly, Kan et al [30] reported that hd, and td were most strongly affected by N-rich compounds, and less significantly by C-rich compounds, stage of succession, and the stage of soil formation.…”

The use of mulching, compost, and their interaction on organic residue (OR) decomposition rate (k), time of residue decay, primming effect, and soil organisms’ community composition was tested in a 16-year P. pyrifolia field experiment conducted from January 2020 to June 2021. A 2 × 2 factorial design was used with compost and mulching as the two factors within four blocks. OR decomposition was characterized by using litter bags with different mesh, and soil organisms were identified at family level. The half-decay rate (hd), total-decay rate (td), and remaining residue mass (Rm) varied among the organic residue management and mesh-type. The highest values of k and primming effect were found in litter bags with 15 mm2 size containing compost in the plots that received compost. For soil organisms’ abundance and richness, the highest values were found on plot that received both mulching and compost. The observed results suggested that the OR management determined organic matter decomposition, soil organisms’ abundance and richness in an Acrisols of the Southern Brazil. Soil organisms were the main factors contributing to the data variance (e.g., Acaridae, Blattidae, Chrysopidae, Halictophagidae, and Forficulidae).

“…The rice residue management practices are anticipated to have a positive impact on increasing P availability, which contributes towards increased crop yield 61 . Significantly higher grain yield in treatments PTR W0 + GM and PTR W25 + GM could be attributed to the addition of green manure which helps to enhance the availability of nutrients.…”

The sustainability of the rice–wheat system is threatened due to the deterioration of soil health and emergence of new challenges of climate change caused by low nutrient use efficiency and large scale burning of crop residues. The conservation agriculture based on tillage intensity, crop residue retention and raising green manuring (GM) crops during the intervening period between wheat harvest and rice establishment offers opportunities for restoration of phosphorus (P) dynamics and stimulate phosphatase activities within the macro-and micro-aggregates. Phosphorus and phosphatase activities in the soil aggregates affected by different residue management practices remain poorly understood. Thus, soil samples were obtained after a five-year field experiment to identify the effect of tillage, green manure and residue management on aggregate-associated phosphorus fractions. Four main plot treatments in rice included combination of wheat straw and GM were conventional till puddled transplanted rice (PTR) with no wheat straw (PTRW0), PTR with 25% wheat stubbles retained (PTRW25), PTR without wheat straw and GM (PTRW0 + GM), and PTR with wheat stubbles and GM (PTRW25 + GM). Three sub-plots treatments in the successive wheat crop were conventional tillage (CT) with rice straw removed (CTWR0), zero tillage (ZT) with rice straw removed (ZTWR0) and ZT with rice straw retained as surface mulch (ZTWR100). Results of the present study revealed significantly higher phosphorus fractions (HCl-P, NaHCO3-Pi and NaOH-Po) in treatment PTRW25 + GM and ZTWR100 compared with PTRW0/CTWR0 within both macro- and micro-aggregates. The total phosphorus (P), available P, alkaline phosphatase and phytin-P were significantly higher under ZTWR100 than CTWR0. The principal component analysis identified NaOH-Po, NaHCO3-Pi and HCl-P as the dominant and reliable indicators for evaluating P transformation within aggregates under conservation agriculture-based practices.
