With the development of economy, contradiction between population, resources, and environment has become more prominent. How to make full use limited cultivated land resources increase food production while reducing damage is an important issue facing agricultural production. Maize plays essential role in ensuring global security. Planting density a key agronomic factor affecting maize yield. Soil organic matter (SOM) indicator soil fertility. However, it unknown whether there are different optimal planting densities under SOM contents optimizing based on further improves grain yield resource efficiency. Therefore, this study aims investigate influence yield, determine relationship (AOPD), compare economic benefits, efficiency sowing at uniform conventional (SUD) versus optimized (SOD). The results showed that AOPD its corresponding increased linearly with SOM. Compared SUD, two experimental sites SOD by 2.2% 5.4%, respectively, benefits 0.4% 4.6%, respectively. average energy efficiency, mass productivity, productivity were all higher than those SUD. above demonstrated theoretically feasible optimize spatial heterogeneity potential sustainable method can fully utilize benefits.

This study explores agronomic management (AM) effects on soil parameters under diverse conditions. Investigating tillage practices (TP), nutrient (NM), crop rotation (CR), organic matter (OM), irrigation (IM), and mulching (MS), it aims to reveal impacts productivity, availability, microbial activity, overall health. Varied TP affect quality through compaction, porosity, erosion risk. Proper NM is vital for cycling, preventing imbalances acidification. CR disrupts pest cycles, reduces weed pressure, boosts recycling. OM enhances by influencing carbon, pH, fertility, water retention. Optimizing IM regulates content without inducing waterlogging. MS contributes content, retention, structure, temperature-moisture regulation, benefiting biota, aggregation, health agricultural productivity. The review emphasizes integrated nutrient, CR, management's positive impact fertility activity. Different variations production. Judicious implementation of these essential sustainable agriculture. synthesis identifies uncertainties proposes research directions optimizing productivity while ensuring environmental sustainability. Ongoing inquiry can guide a balanced approach between yields resilient stewardship future generations.

Developing an intensive sustainable model and feeding a rising population are worldwide challenges. The task is much more daunting in the North Eastern Himalayas, where, low productive maize (Zea mays)- fallow main production system upland. To increase farm productivity, nutritional security, energy dietary returns while maintaining environmental sustainability economic viability, short-duration crops must be included maize-fallow system.A field study was conducted sandy clay loam soil with randomized complete block design three replications for continuous years (2018-2021) under organic management two crop practices, viz., (i) conservation agriculture (ii) conventional agriculture, six diversification options, maize-sweet corn mays saccharata)-vegetable pea (Pisum sativa) (M-SC-VP), corn-mustard (Brassica juncea) (M-SC-M), (iii) corn-lentil (Lens culinaris) (M-SC-L), (iv) corn-vegetable broad bean (Vicia faba) (M-SC-VB), (v) (local)-vegetable (M-VP), (vi) (local)-fallow (M-F).The results showed that, average productivity 5.3% lower than agriculture. System carbohydrate, protein, fat, fiber, were ~6.9, 6.8, 7.8, 6.7, 7%, higher respectively. Similarly, macronutrients (Ca, Mg, P, K) micronutrients yield (Fe, Mn, Zn, Cu) were, 5.2-8% 6.9-7.4% On average, over years, M-SC-VP/M-SC-VB rotation had (158%), efficiency (157%), net (benefit-cost ratio) (44%), (16.6%) local maize-vegetable system. improved security by improving Ca, K, Fe, Cu 35.5-135.7% M-VP system.Conservation significantly (p < 0.05) carbohydrate yield, protein fat fiber production. It concluded that health performed better maize-based cropping systems. Overall indicate can potentially calorie consumption profitability.

The North China Plain (NCP) is a remarkable agricultural area with severe water scarcity and uneven precipitation, especially in wheat season. Optimizing irrigation strategies to increase productivity (WP) achieve higher yield winter wheat-summer maize rotation urgently needed has been persistent challenge. A four-year field experiment was conducted explore the impact of on WP subsequent under different precipitation year types (dry normal years, categorized based cumulative from sowing jointing stage (P1)). Four (W0, no irrigation; W1, pre-sowing W2, + W3, anthesis irrigation) were adopted for wheat, identical operations applied maize. Results showed that affected by P1 rather than total precipitation. Irrigation improved enhancing evapotranspiration, spike number, grain 1000-seed weight. water-limited gap between W2 W1 significantly those W0, W3 implying suitable strategy production. Different season had effect but increased 13.2–29.3% 16.1–41.8% compared other treatments through decreasing soil storage before dry years. Therefore, we recommended annual yield, WP, net income years (37.6 mm < 79.9 mm); lower consumption economic benefits (P1 37.6 mm), respectively. Overall, optimizing conditions an effective cope resource shortages crop NCP.

Long-term rotary tillage limit water infiltration and crop productivity in North China Plain (NCP). The practice of subsoiling to fracture plow pans has made beneficial impacts on soil surface structure infiltration. Further, appropriate irrigation method coupled with regime can improve condition. A three-year field trial (2020–2023) was carried out assess the effects winter wheat evapotranspiration (ET), grain yield (GY), (WP), partial factor from applied nitrogen (PPFN), economic analysis. three regimes were irrigated when moisture levels decreased 70%, 60% 50% capacity (referred as H, M L) two methods drip (SDI) micro-sprinkler (MSI). traditional flood 70% filed CK. results showed optimizing significantly influenced ET, GY, WP, PPFN, net incomes. As amount increased, ET first increased while incomes then slightly decreased. Based average, maximum GY 9454 kg ha−1 income 11089 yuan achieved SDI-M, which had WP 2.3 m−3 PPFN 39.4 kg−1. At same time, SDI-M did not result much increase (average 405.1 mm seasons). Considering comprehensively incomes, irrigate decreases by optimal strategy all aspects. These will provide a scientific reference for management NCP, well similar production areas worldwide.

Water scarcity coupled with reduced nutrient-use efficiency (NUE) is challenging the sustainability of wheat production in North-Western Plains India. Suitable soil tillage practices, water, and nutrient management are thus essential to harvest high yields on a long-term basis. Thus, fixed-plot experiment was set continued for three years assess main interaction effects tillage, irrigation, fertilizers water-use (WUE) yield. Zero-till flat bed (ZTFB) conventional till-raised (CTRB) condensed irrigation water requirement by 1163–1218 m3 ha−1 698–762 ha−1, respectively, compared till-flat (CTFB) without affecting during 2016–2019. Apart from saving CTRB enhanced grain turn over 8.12–31.5%, biomass 3.47–34.1%, WUE 27.0–30.9% productivity (IWP) 55.2–57.5% CTFB. Likewise, recorded 4.4–10.1% greater photosynthetically active radiation (PAR) interception CTFB ZTFB study years. had highest moisture level (11.2%–22.5%) 0–0.3 m layer. Applying at 25% depletion available (DASM) 100% recommended rates nutrients (RRN) resulted significantly lower levels Further, treatment combination or + DASM +100% RRN more productive, registering significant enhancements yields, all other fertilizer levels. The concludes that application under synergic attain higher crop against individual these agronomic variables.
