Energy and economic efficiency of climate‑smart agriculture practices in a rice–wheat cropping system of India
No full textIntensive tillage operations, indiscriminate use of irrigation water, chemical fertilizers, and pesticides
and crop biomass burning have made the conventional rice–wheat (RW) system highly energyintensive
and inefficient. In the recent past, portfolios of climate-smart agricultural practices (CSAP)
have been promoted as a potential alternative to improve the energy efficiency in conventional
RW system. Therefore, to evaluate the energy input–output relation, energy flow and economic
efficiency in various combinations of crop management options, a 3-year (2014–2017) on-farm study
was conducted at Karnal, India. Various portfolio of management practices; Sc1-Business as usual
(BAU) or Conventional tillage (CT) without residue, Sc2-CT with residue, Sc3-Reduce tillage (RT) with
residue + recommended dose of fertilizer (RDF), Sc4-RT/Zero tillage (ZT) with residue + RDF, Sc5-ZT
with residue + RDF + GreenSeeker + Tensiometer, Sc6-Sc5 + Nutrient expert were investigated. Present
study results revealed that net energy, energy use efficiency and energy productivity were 11–18,
31–51 and 29–53% higher under CSAP (mean of Sc4, Sc5 and Sc6) in RW system than Sc1, respectively.
However, renewable and non-renewable energy inputs were 14 and 33% higher in Sc1 compared to
CSAP (4028 and 49,547 MJ ha−
1), respectively, it showed that BAU practices mostly dependents on
non-renewable energy sources whereas CSAP dependents on renewable energy sources. Similarly, the
adoption of CSAP improved the biomass yield, net farm income and economic efficiency by 6–9, 18–23
and 42–58%, respectively compared to Sc1. Overall, the adoption of CSAP could be a viable alternative
for improving energy use efficiency, farm profitability and eco-efficiency in the RW system
Crop performance and nitrogen use-efficiency in maize under conservation agriculture coupled with sub-surface drip fertigation
No full textA field experiment was conducted in maize under medium-term conservation agriculture (CA) based maizewheat
system at BISA-CIMMYT, Ladhowal, Punjab during kharif 2019 to assess the effect of CA+ practices (CA
with sub-surface drip irrigation) with variable N doses on maize. The CA+ treatments were residue retained (WR)
permanent bed (PB) with sub-surface drip fertigation (PB-SSD): without N (N0), 120 kg N/ha,150 kg N/ha applied in
4-equal (Eq) and differential splits (Df); CA alone treatment includ PB furrow irrigation with 120 kg N/ha (PBWRFurrow-
N120); conventional tillage (CT) involved furrow irrigation with 120 kg N/ha (CTWOR-Furrow-N120) and
other treatments were residue removed (WOR) PB: PBWOR-without N (N0), with 120 kg N/ha, and 150 kg N/ha
applied in four Eq-splits and Df-splits. The findings of the present experiment showed that the numerical value of
yield attributing characters were higher under CA+ plots as compared to CA alone (PBWR-Furrow-N120) and CT
(CTWOR-Furrow-N120). Biological yield of maize was significantly higher in all CA+ plots as compared to CA alone
and CT plots. Highest biological yield was recorded under PBWR-SSD-N150 Df (23.45 t/ha). Highest no. of cobs
(72800/ha), no. of grains/cob (605) and cob length (22.61cm) along with dry matter resulted highest biological yield
in PBWR-SSD-N150 plots. The grain N content remained statistically similar across all the N management plots,
but in case of total N uptake, PBWR-SSD-N150 Df (CA+) plots dominated due to higher biomass. Besides, CA+
based PBWR-SSD-N120 (average of Df and Eq) registered 23-24% higher total N uptake than CA alone (PBWRFurrow-
N120) and conventional (CTWOR-Furrow-N120) plots. Improved agronomic N use-efficiency was also
recorded under CA+ plots as compared to CA alone (36.4 kg/kg N) and CT (36.7 kg/kg N) plots
2018 CIMMYT Maize Latin America Product Announcement for Product Profile LA-PP1C / Anuncio de Productos de Maíz de CIMMYT en Latinoamérica por el Perfíl de Productos LA-PP1C
No full textNew and improved maize hybrids, developed by the CIMMYT Global Maize Program, are available for uptake by public and private sector partners, especially those interested in marketing or disseminating hybrid maize seed across Latin America and similar agro-ecological zones. Following a rigorous trialing and a stage-gate advancement process culminating in the 2018 Stage 5 trials, CIMMYT advanced a total of two new elite maize hybrids in Latin America in 2018. These are yellow maize hybrids adapted for the tropical lowlands (Product Profile LA-PP1C). Phenotypic data collected in Stage 4 and Stage 5 trials for the two selected hybrids as well as information about the trial sites are provided in this dataset. These trials were conducted through a network of partners, including NARS and private seed companies, in Latin America under various management and environmental conditions.
Nuevos y mejorados híbridos desarrollados por el Programa Global de Maíz del CIMMYT se ponen a disposición de instituciones del sector público y privado, especialmente para aquellas instituciones colaboradoras interesadas en la comercialización y diseminación de semilla de maíz en Latinoamérica o en zonas agroecológicas similares. Después de un riguroso proceso de evaluación de germoplasma en distintas etapas que culminó en ensayos de evaluación de híbridos en etapa cinco, el CIMMYT avanzó dos nuevos híbridos élite en Latinoamérica en 2018. Esos son hibrídos de maíz amarillo adaptados por las tierras bajas tropicales (Perfíl de Producto LA-PP1C). Datos fenotípicos recopilados en los ensayos en etapa cuatro y cinco, además de información sobre los sitios están incluidos en este conjunto de datos. Estos ensayos fueron conducidos bajo diferentes condiciones de manejo y ambientes a través de redes colaborativas con instituciones de investigación pública y empresas semilleras de Latinoamérica
