Water budgeting in conservation agriculture-based sub-surface drip irrigation using HYDRUS-2D in rice under annual rotation with wheat in Western Indo-Gangetic Plains
No full textRapidly depleting groundwater in western Indo-Gangetic Plains (IGP) is a major threat to food security in South
Asia. Conventional tillage-based and flood irrigated puddled transplanted rice (PTR) is a major contributor to
faster depleting aquifers. Urgent actions are therefore warranted to develop alternate productive, profitable,
water and N-use efficient rice production practices for rice-wheat (RW) cropping system. Conservation agriculture
(CA) based direct-seeded rice (DSR) has been advocated as a potential alternative to PTR. Further,
bundling CA with precision water and N management using sub-surface drip irrigation (SSD) has demonstrated
significant benefits over CA-based flood irrigation (FI). However, for more efficient use of water, water budgeting
is needed which is a challenging task as it requires expensive tools, and time, and efforts. Information about
complete water budgeting in high water demanding crops like rice grown under CA-based SSD, FI, and PTR are
not available. We deployed HYDRUS-2D model for estimating water budgeting of rice under CA+ (CA-based
SSD), CA-based FI, and PTR-based systems. The objective of our study was to calibrate and validate the HYDRUS-
2D model to simulate water dynamics in rice grown under CA-based SSD and FI compared to PTR and to design
water and N- use efficient production practices for rice cultivation in western IGP. Five treatments comprised of
PTR+FI with 120 kg N ha 1 (PTR), zero-till direct-seeded rice (ZTDSR)+FI without N (ZT-N0), ZTDSR+FI with
100% of N recommended dose (ZT-N100), ZTDSR+SSD without N (SSD-N0), and ZTDSR+SSD with 100% of Nrecommended
dose (SSD-N100) were compared. The result showed that the HYDRUS-2D model satisfactorily
simulated the soil moisture content with low root mean square error (RMSE) (0.014–0.028), high coefficient of
determination (74–92%), and model efficiency (59–87%) during the simulation period (80 days: 35–114 days
after sowing). The highest grain yield (7.18 t ha 1) was observed in the PTR treatment, which was statistically
similar to SSD-N100 (6.54 t ha 1) and significantly higher than ZT-N100. During the simulation period, PTR
plots received 131.7 cm of water (rainfall + irrigation) which was 27.3% and 50.1% higher than ZT-N100 and
SSD-N100 plots, respectively. Out of the cumulative water applied, PTR transpired only 18.4% of applied water,
compared to 24% in ZT-N100 and 36.3% in SSD-N100. Interestingly, SSD-N100 plots recorded 20.6% and 23.5%
less evaporative loss and 45.0% and 66.0% less water loss by deep drainage than ZT-N100 and PTR, respectively.
Thus, conversion to CA+ system with 100% N-recommended dose saved 50.1% and 31.3% of water, and
consequently attained 2.0 and 1.45-times higher biomass water use efficiency than PTR and ZT-N100, respectively.
Based on the results, CA-based SSD could be recommended for precise utilization of water and to curtails
the unproductive water loss components such as evaporation and deep drainage
Community survey on stresses in maize production in six agroecological zones in Kenya
No full textThis data set presents the results of 121 focus group discussions with men and women, in randomly selected communities, therefore representative of the six major maize agroecological zones in Kenya. Topics include biotic and abiotic stresses, in particular storage pests, maize lethal necrose disease, fall army worm and drought. Communities were asked what the major stresses were, to estimate the losses, and describe control methods and coping strategies

Consumers’ study with instant fortified pearl millet products using affective tests and experimental auctions in Touba, Senegal
No full textFor this study, 201 consumers from Touba Senegal, were invited to evaluated four new flour products in comparison with the conventional pearl millet flours: instant pearl millet flour, instant pearl millet flour pearl millet flour, instant pearl millet flour with added dry mango and carrot powder (Food-to-Food fortification), and the previous product with added conventional chemical added dry mango and carrot powder (naturally fortified), and the previous products with added conventional chemical micronutrient premix and the food-to-food fortification. Consumers' acceptance was measured with affective tests on all the products, prepared as porridge, on five sensory traits: appearance, aroma, texture, taste and overall- score, using a five-point Likert scale (1 = dislike very much, 2 = dislike, 3 = neither dislike nor like, 4 = like, 5 = like very much. Willingness to pay (WTP) for the products was elicited through experimental auctions, in particular the BDM mechanism. Participants were randomly divided into two information treatments: in the first group the WTP was first elicited without information on the product’s content, followed by the same WTP experiment after providing information; in the second group information was given directly followed by the WTP experiment

Phenotypic data of HIBAP I panel under yield potential and heat stress conditions
No full textPhenotypic data of HIBAP I panel evaluated under yield potential and heat stress conditions during Obregon wheat seasons 2015-16 and 2016-17. Combined data across years per environment. The HIBAP I panel is comprised of 149 high biomass spring wheat lines of a variety of elite and exotic backgrounds. It was demonstrated how strategic integration of exotic material significantly increases yield under
heat stress compared to elite lines, with no significant yield penalty under favourable conditions. Through genome wide association analysis three marker trait associations were revealed. The yield increase was associated with lower canopy temperature. An Aegilops tauschii introgression was identified as the most significant of these associations. Publicly available sequencing data used in this study is available at the European Nucleotide Archive (ENA). More information about the location of sequencing data can be found in the section 'Data availability' of the referenced manuscript at https://doi.org/10.1101/2022.02.09.479695
