Organic amendments improve general soil conditions and stabilize crop production, but their effects on the soil hydrothermal regime, root distribution, and their contributions to water productivity (WP) of maize have not been fully studied. A two-year field experiment was conducted to investigate the impacts of organic amendments on soil temperature, water storage depletion (SWSD), root distribution, grain yield, and the WP of summer maize (Zea mays L.) in the Guanzhong Plain of Northwest China. The control treatment (CO) applied mineral fertilizer without amendments, and the three amended treatments applied mineral fertilizer with 20 Mg ha−1 of wheat straw (MWS), farmyard manure (MFM), and bioorganic fertilizer (MBF), respectively. Organic amendments decreased SWSD compared to CO, and the lowest value was obtained in MBF, followed by MWS and MFM. Meanwhile, the lowest mean topsoil (0–10 cm) temperature was registered in MWS. Compared to CO, organic amendments generally improved the root length density (RLD) and root weight density (RWD) of maize. MBF showed the highest RLD across the whole soil profile, while MWS yielded the greatest RWD to 20 cm soil depth. Consequently, organic amendments increased grain yield by 9.9–40.3% and WP by 8.6–47.1% compared to CO, and the best performance was attained in MWS and MBF. We suggest that MWS and MBF can benefit the maize agriculture in semi-arid regions for higher yield, and WP through regulating soil hydrothermal conditions and improving root growth.

Application Methods

Improvement in fertilization methods, including the optimal matching of nutrient supply and root nutrient absorption by applying nitrogen (N) in the root zone of crop, is necessary to improve N use efficiency (NUE), maintain high stable yield cultivation of maize, and contribute toward future environmental protection. The current practice of split surface broadcasting (SSB) of N is labor-intensive and the surface broadcasting causes a large amount of N to leach into the environment, yet it does not substantially increase maize yield. Root zone fertilization (RZF) has been identified as an efficient way to solve such problems. However, information on the appropriate amount of N fertilizer under RZF for summer maize remains limited. Therefore, in this study, a two-year consecutive field experiment was conducted during 2015–2016 in Anhui province, China, to investigate the effect of N rate and application method on grain yield, nutrient uptake, and NUE of summer maize. The method chosen is not only important to increase grain yield but also critical for reducing N rate and potential loss in the maize cropping system. The experiment comprised six N rates (90, 135, 180, 225, 270, and 360 kg N hm−2) and two N application methods in both 2015 and 2016. The two N application methods included SSB and one-time RZF. Results showed that grain yield of summer maize increased first and then decreased with the increase of N rate; however, when the N rate increased to 270 kg hm−2, the grain yield increased slowly or even decreased. Compared with SSB, RZF increased grain yield by 4%, and the effect of N on grain yield was mainly related to the number of kernels per ear and 1000-seed weight. One-time RZF increased N apparent recovery efficiency by 18% (7.2 percentage points) compared with SSB and also improved the N agronomic efficiency, N physiological efficiency, and N partial factor productivity. In the comprehensive consideration of yield target, NUE, and soil N balance, the optimal N rate for summer maize in the vertisol soil of Anhui province was 180–225 kg hm−2 for one-time RZF, which reduced N fertilizer by 14% compared with the SSB. Overall, one-time RZF has great potential for green and sustainable agriculture, and thus fertilization machines are worthy of development and application in maize cropping systems.

In an agricultural drought risk system, crop drought loss sensitivity evaluation is a fundamental link for quantitative agricultural drought loss risk assessment. Summer maize growth processes under various drought patterns were simulated using the Cropping System Model (CSM)-CERES-maize, which was calibrated and validated based on pit experiments conducted in the Huaibei Plain during 2016 and 2017 seasons. Then S-shaped maize drought loss sensitivity curve was built for fitting the relationship between drought hazard index intensity at a given stage and the corresponding dry matter accumulation and grain yield loss rate, respectively. Drought stress reduced summer maize evapotranspiration, dry matter, and yield accumulation, and the reductions increased with the drought intensity at each stage. Moreover, the losses caused by drought at different stages were significantly different. When maize plants were exposed to a severe water deficit at the jointing stage, the dry matter and grain yield formation were greatly affected. Therefore, maize growth was more sensitive to drought stress at the jointing stage when the stress was serious. Furthermore, when plants encountered a relatively slight drought during the seedling or jointing stage, which represented as a lower soil water deficit intensity, the grain yield loss rates approached the maximum for the sensitivity curves of these two stages. Therefore, summer maize tolerance to water deficit at the seedling and jointing stages were weak, and yield formation was more sensitive to water deficit during these two stages when the deficit was relatively slight.

A field experiment was conducted during rabi seasons of 2007-08 and 2008-09 on mollisols at G.B. Pant University of Agriculture & Technology, Pantnagar to study the performance of fieldpea (Pisum sativum L.var arvense) under different planting methods, irrigation levels and weed management practices. Results revealed that growth attributes as plant height, number of branches and dry matter accumulation per plant, number and dry weight of nodules per plant, density and dry matter of weeds/unit area, nutrient uptake and yield attributes as pods/plant, 1000-grain weight, grain yield/plant and grain yield of fieldpea were significantly higher under raised bed planting as compared to flat bed. Planting on raised bed increased grain yield of fieldpea by 17.5% over flat bed. Two irrigations applied at critical stages i.e. pre-flowering and pod formation proved promising in increasing the growth, nutrient uptake, yield attributes and grain yield of pea. One hand weeding done at 25 days after sowing (DAS) reduced the density and dry matter of weeds significantly and one hand weeding done at 25 DAS increased the values of growth attributes, number and dry weight of nodules, nutrient uptake, yield attributes and grain yield as compared to pendimethalin 1.0 kg a.i./ha applied as pre-emergence and weedy check.

A field experiment was carried out during summer season of 2018 at Instructional Farm, Jaguli, BCKV, West Bengal to study the effect of integrated nutrient management on growth, yield and economics in hybrid maize. The treatments were T1-100% RDF (150:75:75 kg/ha N, P2O5 and K2O) (control), T2- 75% RDF+ Vermicompost @ 2t/ha, T3-75% RDF+ Yeast Vinasse @ 2t/ha, T4-75% RDF+ Vermicompost @ 2t/ha+ soil application of ZnSO4 @ 25 kg/ha, T5-75% RDF+ Yeast Vinasse @ 2t/ha+ soil application of ZnSO4 @ 25 kg/ha, T6-75% RDF+ Vermicompost @ 2t/ha+ Foliar application of ZnSO4 @ 0.5% and T7-75% RDF+ Yeast Vinasse @ 2t/ha+ Foliar application of ZnSO4 @ 0.5% replicated thrice in RBD. The result of the experiment revealed that application of vermicompost @ 2 t/ha along with 75% RDF and 0.5% foliar application of ZnSO4 (T6) exhibited maximum plant height (250.97 cm), LAI (4.58), dry matter accumulation (1680.38 g/m2), number of grains/cob (402.64), cob length (22.34 cm), grain yield (9.04 t/ha), stover yield (13.50 t/ha), net return (Rs.77112/ha), BCR (2.33) and uptake of N, P2O5 and K2O (200.54, 66.45 and 119.12 kg/ha respectively) over application of 100% RDF. However, T6 was statistically at par with the T4 and T7, which produced 8.94 and 8.75 t/ha grains respectively. Therefore, the study concluded that integrated application of vermicompost @ 2 t/ha along with 75% RDF and 0.5% foliar application of ZnSO4 can be recommended for better grain yield and higher profit of summer maize.
