Report Stakeholders Consultation Workshop Growing Project August 2022

The Generating Revenues & Opportunities for Women to Improve Nutrition in Ghana (GROWING) is an integrated climate-smart, nutrition-agriculture-marketing project focusing on transforming the individual agencies of women, thus creating an enabling environment and appropriate practices to address key gender inequities to ensure more equitable outcomes. As part of the participatory planning and implementation processes, the GROWING project facilitated the stakeholders’ consultative workshop during Aug 1-4, 2022 in Tamale, Ghana. Accordingly, 41 key participants (17 women) representing main stakeholders and implementing partners have been identified and attended the workshop. These key partners encompass Ghana Health Services (GHS) (national, regional and district levels), Ministry of Food and Agriculture (MOFA) (national, regional and district levels), the Women in Agriculture Development Directorate (WIAD) (which is
part of MOFA), University of Development Studies (UDS) (key staff from the departments of nutrition, behavioral studies and agricultural economics and business), private actors (a cavy rearing young man and a sweetpotato vine multiplier) and an environmental consultant.

Standard operating procedures for sweetpotato breeding data management. COP Breeding Data Management SweetGAINS

Current modernization efforts of sweetpotato breeding operations in Africa establish a new mindset. A modern sweetpotato breeding program continuously generates vast amounts of data on which it depends for all decision making throughout the program. Without a proper systematization of efforts, it is likely that significant mistakes can be unwillingly made, which would impact in a negative manner both genetic gains and the adoption of new varieties by smallholders. This document describes standard operating procedures (SOPs) for implementing breeding data workflows to ensure that all necessary breeding data are recorded appropriately and made easily accessible. This document needs to be considered as an alive one, as through its ensuing iterations additional SOPs will be added, and the current ones would be modified to reflect the learnings acquired. The data management SOPs in this volume cover the following key sweetpotato breeding data workflows: phenotyping, crossing, quality assessment, germplasm management, and DNA sample management. A relational database, SPBase (www.sweetpotatobase.org)1, plays a central role as a breeding data management system across workflows. Several other digital tools have been developed to connect to SPBase to facilitate recording and uploading different types of data.

Quality Diets for Better Health Healthy Living Clubs

Quality Diets for Better Health (QDBH) is a CIP-led intervention in the Southern Nations, Nationalities and Peoples’ and the Sidama regions in the South of Ethiopia. The project strives to reach 15,000 direct beneficiary households with OFSP planting material and nutrition training aiming mainly at improved diets and vitamin A intake of pregnant and lactating women and children under two years old. The training vehicle are so-called Healthy Living Clubs:  groups over 30 households that receive training in sweetpotato farming and appropriate child nutrition practices. Due to the COVID-19 pandemic face-to-face trainings could only be given to smaller groups and an adapted training program of four sessions was developed. This document contains the adapted training curriculum developed by Rollins School of Nutrition of Emory University, one of the project’s implementing partners.

Report on Sweetpotato value chain study: Exploring opportunities to promote greater exploitation of the benefits of Sweetpotato in representative states of Nigeria.

This report is the output of a study undertaken as part of the Sweetpotato Action for Security and Health in Africa (SASHA) Project, which aims to improve “food security and livelihoods of 150,000 poor households in Sub-Saharan Africa (SSA) by exploiting the untapped potential of sweetpotato”.

The study seeks to explore how Nigeria, which ranks third in global output of the crop, can exploit the benefits of sweetpotato in both its food and farming systems. Sweetpotato is not only a good source of carbohydrates, fibre and many micronutrients but also the orange-fleshed varieties are especially rich in beta-carotene, the precursor to vitamin A. Hence, increased consumption of the orange-fleshed sweetpotato can significantly reduce Vitamin A deficiency (VAD) and associated conditions such as blindness and premature death in children and pregnant women. Cultivation of this versatile crop requires fewer inputs and less labour than other staple crops but, in contrast with other low-input starchy staples such as cassava, it is a relatively higher value crop with a rather short gestation period and, therefore, can potentially offer poor households an effective means to optimise farm-based earnings.

The study was specifically intended to generate evidence on the desirability and feasibility of investing in development of sweetpotato value chains for fresh root marketing and processed products in the major producing areas and markets.

Sweet potato (Ipomoea batatas) vine silage: a cost-effective supplement for milk production in smallholder dairy-farming systems of East Africa?

Abstract
Context. Dairy production in East Africa is dominated by smallholder production systems, but is dogged by suboptimal milk production mediated by poor nutrition. Grain-based concentrates can be used to make the energy and protein deficits in rain-fed systems, but this strategy faces several hurdles. For livestock production systems to be sustainable, it is important that less human-edible food is fed to animals and sweet potato can serve both as a source of human food (tuber) and animal feed (vines). Smallholder scale-appropriate technology has been used to allow feed preservation of the perishable sweet potato vines for use throughout the year.


Aims. We assessed the efficacy of sweet potato vine silage plus wheat bran (SPVSWB) as a supplement to maintain milk production at a lower cost than that of grain-based commercial dairy concentrate (CDC).
Methods. Multiparous Holstein–Friesian cattle (n = 12) were given a basal diet of Napier grass (Pennisetum purpureum cv. South Africa), ad libitum, plus a fixed amount of either SPVSWB or CDC, (designed to be both isonitrogenous and iso-caloric) during late (LL) and early (EL) lactations.


Key results.Daily milk yield was lower for SPVSWB than for CDC groups, although comparable (not significant), in both LL (6.2 vs 7.5 L/day) and EL (14.2 vs 16.0 L/day); however, the lower cost of production for SPVSWB (23.2 vs 48.7 KES/kg DM) ensured that margins on milk income over feed (per cow per day) were greater for SPVSWB in both periods. (LL: 71 vs 14.5; and EL: 426 vs 400 KES/day). The lower intake for SPVSWB than for CDC is most probably due to high neutral detergent fibre content in the supplement and the lower milk production, owing to either, or both, of lower energy and protein intake.


Conclusions. It is suggested that some reformulation of SPVS, replacing in part or in whole the Napier grass with rejected sweet potato tubers, will decrease the neutral detergent fibre content, increase the metabolisable energy content, reducing the need for additional wheat bran and may, thereby, enhance the production response to equate with that of CDC.


Implications.It is clear that, despite SPVSWB eliciting lower milk production (LL 6.2 and EL14.2 L/day) than does CDC (LL 7.5 and EL 16.0 L/day), SPVSWB is a cost-effective, accessible alternative to grain-based supplementation in small-holder dairy-farming systems of Kenya.

Topic 20: Sweetpotato weevil management?

Sweetpotato weevil is the most serious pest of sweetpotato, with reported losses ranging from 5% to 80% worldwide. The larva, which feeds both on stems and roots, is the most destructive stage of the insect.  The control of sweetpotato weevil has met some degree of difficulties. It’s presence inside the tubers protects it from contact pesticides and most arthropod natural enemies. As part of integrated pest management, numerous chemical insecticides have been tested for the control of sweetpotato weevils.  Control achieved by post planting application of chemical insecticides appears to be due to mortality of adult weevils in search of feeding sites. Movement of the adult weevil may facilitate the contact between the toxicant and the insect, thereby resulting in insect mortality.  This method may require frequent application for it to be effective. 

However, frequent application of insecticides is not cost effective, hence not making economic sense to smallholder farmers due to the low market price of sweetpotato in most countries in Africa. In addition, a high proportion of these chemicals may be toxic and may have adverse effects on human health, wildlife, local food sources such as cattle or fish, beneficial insects and biodiversity. Will researching in innovative and cutting edge non-chemical pest management approaches be a breakthrough that will strike a balance between improving smallholder farmers livelihood through improved yields and sustainable environmental management?

Topic 19: Scaling up Triple S: Why, what and how should we do it for significant impact?

Timely access to enough quantities of quality planting material is a key limiting factor in sweetpotato production in Sub-Saharan Africa. This is exacerbated by unpredictable changes in climatic conditions which makes it difficult to conserve planting material during the dry seasons.   Triple S is one of the technologies that can help address this. Triple S involves Storing sweetpotato roots in Sand and letting them to Sprout when it is about to rain. Some stories about the benefits of Triple S are available on http://www.rtb.cgiar.org/blog/2019/03/13/small-investment-big-results/ and https://www.sweetpotatoknowledge.org/champion-farmer-household-contributes-scaling-use-triple-s-technology/ .  Concerted efforts are needed in scaling up the technology to benefit more farmers. The 2019 SSS-CoP online discussions started with experience and knowledge sharing on Triple S with an aim of proposing ways through which the technology can benefit more farmers. Led by Mihiretu Cherinet, the discussion was held on April 8 – 23, 2019.

Why Triple S

Triple S which refers to ‘Storage in Sand and Sprouting’ provides planting material from storage roots in areas with a long dry season. In such areas, farmers often obtain sweetpotato planting material from roots which have been overlooked during harvest and sprout when it rains. However:

  1. The roots sprout only when it rains and planting material only becomes available some weeks afterwards
  2. The roots may sprout in distant fields, unprotected from grazing animals and thieves.

Topic 18: Tapping ICTs for better sweetpotato seed systems

Several studies have shown that Information and Communication Technologies (ICT)-enabled platforms can improve farmer access to extension services, market information, financial services and inputs including improved seed. There are also efforts aimed at applying ICTs in seed systems for vegetatively propagated crops. For instance, the Seed Tracker developed by IITA is a comprehensive WebApp for seed value chain management, monitoring, evaluation and learning. It supports seed production planning, seed traceability (from production to end-use over generations and seasons), seed quality certification, seed inventory, real-time tracking of production fields, seed certification, marketing, information resources, geographic maps and map-based data navigation, and decision support tools.
