R. Br. emend Stuntz] + clusterbean [Cyamopsis tetragonaloba (L.) Taub] intercropping system (PCIS). In current study, the pearl millet grain yield under sole pearl millet was at par with PCIS while its stover yield reduced by 5%. Under PCIS, inclusion of clusterbean led to significant reduction in clusterbean yield compared to its sole stand, however, PCIS system productivity was more over their sole crop stands, indicating that additive series of PCIS may bring more net economic gains over their sole stands in semi-arid ecology of India. The coarse cereal-legume interactions under PCIS have also led to improved protein content in pearl millet (11.2%) over its sole stand (10.7%). Zinc (Zn) and iron (Fe) deficiency is a common feature in semi-arid India and the crops grown as well. Study revealed that Zn and Fe content in pearl millet were increased by 6.5 and 1.6%, respectively, by the inclusion of clusterbean in PCIS. Plant growth, yield attributes and yield of pearl millet and clusterbean crops showed an improvement under flat sowing + organic mulching (FS+OM) over ridge and furrow sowing (RFS) but the differences were non-significant. Among organic nutrient sources, leaf compost (LC) @ 10 t/ha and FYM @ 10 t/ha produced significantly more system productivity in terms of pearl millet-equivalent-yield (PEY) than 100% RDF and control. Protein content both in pearl millet and clusterbean, and Zn and Fe biofortification in pearl millet grains was higher under FYM treated plots closely followed by LC, and leaf + cowdung mixture compost. Application of organics especially FYM @ 10 t/ha also resulted in improved soil health in terms of bulk density, soil organic carbon and NPK status after three years experimentation.

Conventional and zero tillage resulted in comparable weed density, dry weight, chilli fruit yield, fruit length and plant height. Tank-mix pre-emergence application of pendimethalin 0.75 kg/ha + imazethapyr 0.075 kg/ha was next to weedfree check and superior to all the other weed-control treatments in reducting the weed density. Uptake of N, P and K by chilli plants was comparably higher in weed-free check and tank-mix pre-emergence application of pendimethalin 0.75 kg/ha + imazethapyr 0.075 kg/ha. Conversely, N, P and K uptake by weed was significantly higher in weedy check, and the lowest amount of these nutrients after weed-free check was observed in pendimethalin 0.75 kg/ha + imazethapyr 0.075 kg/ha. All the weed-control treatments resulted in significantly higher chilli fruit yield than to weedy check; however, the tank-mix pre-emergence application of pendimethalin 0.75 kg/ha + imazethapyr 0.075 kg/ha resulted in 180% higher chilli fruit yield over weedy check. Similarly, chilli fruit yield was increased by 5.2% in zero tillage over conventional tillage and by 18.2% in the second year over the first year.

The strategy did not explicitly recognise the need to raise farmers' income and did not mention any direct measure to promote farmers' welfare. The low and highly fluctuating farm income is causing detrimental effect on the interest in farming and farm investments, and is also forcing more and more cultivators, particularly younger age group, to leave farming. This can cause serious adverse effect on the future of agriculture in the country (Chand, 2017). The strategies suggested by various authors included expanding

Identifying variation in these parameters may help discover the plausible causes for crop productivity differences under various management practices and cropping systems. Thus, a 2-year (2019–2020) study was undertaken to investigate how far the integrated crop management (ICM) modules and cropping systems affect maize physiology, photosynthetic characteristics, crop vigour and productivity in a holistic manner. The treatments included nine main-plot ICM treatments [ICM1to ICM4– conventional tillage (CT)-based; ICM5to ICM8– conservation agriculture (CA)-based; ICM9– organic agriculture (OA)-based] and two cropping systems,viz., maize–wheat and maize + blackgram–wheat in subplots. The CA-based ICM module, ICM7resulted in significant (p< 0.05) improvements in the physiological parameters,viz., photosynthetic rate (42.56 μ mol CO2m–2sec–1), transpi...

The experiment was laid out in a randomized block design with three replications and eight treatment combinations i.e., ICM modules (ICM 1 to ICM 8). The study revealed that the plant height, dry matter accumulation at different growth stages and grain yield (4.03 t ha-1) of direct-seeded basmati rice under different ICM modules were statistically and numerically higher in the ICM 7 i.e., zero till (ZT)-summer mungbean residue retention (SMB-RR) + ZT-direct seeded rice (DSR) + wheat residue @ 3 t ha-1 + 75% of recommended dose of fertilizers @ 100:50:50 N: P 2 O 5 : K 2 O kg ha-1 (RDF) (N through Zn coated urea/ZCU) + glyphosate as pre-plant (PP) @ 1 kg a.i. ha-1 + pretilachlor as pre-emergence (PE) @ 0.75 kg a.i. ha-1 followed by bispyribac-sodium @ 25 g a.i. ha-1 as post emergence (POE) at 25 days after sowing (DAS) + need based water management, disease and integrated pest management, with comparison to other modules. Direct seeding of rice in ICM 7 module increased grain yield by 4.13, 9.51 and 19.9% over direct seeding/transplanting under ICM 8 (ZT-SMB-RR + ZT-DSR + wheat residue @ 3 t ha-1 + 50% RDF + AMF + NPK-biofertilizers (liquid formulation) + glyphosate as PP @ 1 kg a.i. ha-1 + pretilachlor-PE @ 0.75 kg a.i. ha-1 fb bispyribac-sodium @ 25 g a.i. ha-1 as POE at 25 DAS + 1 HW), ICM 1 (Conventional transplanting/TPR + 100% of RDF + butachlor-PE @ 1 kg a.i./ha + 1 HW) and ICM 2 (TPR + 75% RDF (N as ZCU) + NPK-biofertilizers + butachlor as PE @ 1 kg a.i. ha-1 + 1 HW) modules. This study suggests that zero-tilled direct-seeded rice in wheat and summer mungbean residue retained plots (ICM 7) with adoption of suitable weed management practices produced comparable yields as in transplanted rice (ICM 1).

Merr.]. Six phosphorus fertilization treatments, viz. control (no P), 15 kg P2O5/ha, 30 kg P2O5/ha, 45 kg P2O5/ha, 60 kg P2O5/ha and 75 kg P2O5/ha, were applied in 4 replicates. The highest seed yield (2.47 t/ha) was recorded with the application of 75 kg P2O5/ha, the increase being ∼34.3% over the control (no phosphorus). Similarly, cost of cultivation increased with increasing rate of phosphorus (P), 75 kg P2O5/ha was the costliest treatment among the treatments. Application of 75 kg P2O5/ha resulted in the highest gross (163.9 × 103 /ha) and net returns (84.90 × 103 /ha) followed by 60 kg P2O5/ha, however, the maximum benefit: cost ratio was recorded with 60 kg P2O5/ha.

On a global scale, N is agriculture’s most widely used fertilizer nutrient. Studies have shown that crops use only 50% of the applied N effectively, while the rest is lost through various pathways to the surrounding environment. Furthermore, lost N negatively impacts the farmer’s return on investment and pollutes the water, soil, and air. Therefore, enhancing nitrogen use efficiency (NUE) is critical in crop improvement programs and agronomic management systems. The major processes responsible for low N use are the volatilization, surface runoff, leaching, and denitrification of N. Improving NUE through agronomic management practices and high-throughput technologies would reduce the need for intensive N application and minimize the negative impact of N on the environment. The harmonization of agronomic, genetic, and biotechnological tools will improve the efficiency of N assimilation in crops...

The zinc concentration in different parts of wheat was found highest in grain followed by spike straw and lowest in straw. Among the tested varieties, highest Zn concentration (40.6 mg/kg) and uptake (189.2 g/ha) in grain was registered in HD 2851 and HD 2967 varieties, respectively. Zinc recovery efficiency of HD 2687 (2.5%) was registered highest among the tested varieties. Highest Zn mobilization efficiency index (ZnMEI) was recorded in HD 2967 variety. Zinc fertilization increased zinc induced nitrogen recovery efficiency (ZniNRE) of all the tested varieties to the tune of 7.4-12.7%. Application of Zn in wheat crop increased Zn concentration in grain by 7-12%. Uptake of Zn was increased 5.2-5.6% in soil + foliar application in comparison to soil application alone. The highest Zn concentration and uptake in grain, and Zn use efficiencies were recorded with the application of 1.25 kg Zn/ha through Zn-EDTA as soil application + 0.5% foliar spray at maximum tillering and booting stage.
