Effectiveness of Millet-Pulse-Groundnut Based Formulations in Improving the Growth of Pre-School Tribal Children in Telangana State, India.

A community-level nutritional intervention was implemented among tribal children (3 to 6 years of age) in Telangana, India. The one-year intervention involved six nutrient-rich formulations of millet-pulse-groundnut-based products suited to local taste preferences. Anthropometric measurements of height, weight, and mid-upper-arm circumference (MUAC) along with haemoglobin (Hb) levels were monitored at baseline and endline. The treatment group showed considerable gains in height (3.2 cm), weight (1.68 kg), and MUAC (0.33 cm) over the control group. The paired t-test indicated significant differences (p < 0.01) between the pre- and post-intervention anthropometric measurements. Positive shifts were observed in terms of wasting (WHZ; -1.2 ± 1.3 to -0.9 ± 1), stunting (HAZ; -1.8 ± 1.6 to -0.3 ± 1.3), and underweight (WAZ; -1.9 ± 1.2 to -0.7 ± 1) in the treatment group. The Hb levels in the treatment group also improved significantly from 9.70 ± 0.14 g/dL (moderately anaemic) to 11.08 ± 0.13 g/dL (non-anaemic). Post-intervention focus group discussions (FGDs) involving mothers and teachers confirmed these positive impacts. Thus, a nutritional intervention formulated using climate-resilient millets, pulses, and groundnuts promotes dietary diversity and improves the nutrition and health statuses of children.

Depth of soil compaction predominantly affects rice yield reduction by reproductive-stage drought at varietal screening sites in Bangladesh, India, and Nepal.

AIMS: Drought is the major constraint to rainfed rice productivity in South Asia, but few reports provide detailed characterization of the soil properties related to drought stress severity in the region. The aim of the study was to provide a compilation of drought breeding network sites and their respective levels of drought stress, and to relate soil parameters with yield reduction by drought. METHODS: This study characterized levels of drought stress and soil nutrient and physical properties at 18 geographically distributed research station sites involved in rice varietal screening in Bangladesh, India, and Nepal, as well as at farmers' fields located near the research stations. RESULTS: Based on soil resistance to penetration profiles, a hardpan was surprisingly absent at about half of the sites characterized. Significant relationships of depth of compaction and yield reduction by drought indicated the effects of soil puddling on susceptibility to cracking, rather than water retention by hardpans, on plant water availability in this region. The main difference between research stations and nearby farmers' fields was in terms of soil compaction. CONCLUSIONS: These results present an initiative for understanding the range of severities of reproductive-stage drought stress in drought-prone rainfed lowland rice-growing areas in South Asia.
