“…Mudatenguha et al (2014) also reported that the use of insitu rainwater harvesting in combination with organic and inorganic fertiliser increase grain and stover yields. Results from this study were also in agreement with results by Kilasara et al (2015) who reported increased sorghum stover after combining insitu rainwater harvesting with farm yard manure and mineral fertiliser. Findings from this study also support results by Milkias et al (2018) who reported increased maize stover yields after using insitu rainwater harvesting and integrated nutrient management.…”

“…This was in support with results by Mudatenguha et al (2014) who reported high yields from zai pits. The results also concur with results by Kilasara et al (2015) and Milkias et al (2018) who reported higher yields from using inorganic fertiliser in sorghum production and maize production respectively. These results were in support of findings by Shumba et al (2020) who indicated that mineral fertiliser produces higher maize grains when used alone.…”

“…The results coincides with results by Muchai et al (2020) who reported that zai pits were amended with soil fertility options to improve maize, sorghum and millet in Kenya. The results were similar from findings by Kilasara et al (2015) who reported improved sorghum yields from combination of insitu rainwater harvesting and integrated nutrient management options in Tanzania. Higher maize yields from treatment with mineral fertiliser and cattle manure concur with results by Shumba et al (2020) who reported increased maize grain yields in Zimbabwe after combining cattle manure and mineral fertiliser.…”

“…Nyamangara et al (2005) reported that cattle manure contains both macro and micro-nutrients which improves grain yields and soil properties. This was also affirmed by Shumba et al (2020) and Kilasara et al (2015) who all reported that cattle manure improves water retention and releases nutrients slowly in the plant root zone which later improve plant growth and yields. Interactive effects of insitu rainwater harvesting and inorganic manure show significant different (p=0.043) between treatments of tied ridges and zai pits in combination with inorganic manure in the first year.…”

Moisture stress and inherent soil fertility caused huge loss in crop production. The use of insitu rainwater harvesting and integrated nutrient management can improve soil health and crop production. The Objective of the study was to evaluate the effects of integrated nutrient management and insitu rainwater harvesting on maize productivity in dry regions of Zimbabwe. Experiment was laid out as a factorial with three main factors which include cattle manure, insitu rainwater harvesting and inorganic manure. Data was collected from harvested net plot to obtain maize grain and stover yields for two growing years. Data was analysed based on analysis of variance using IBM SPSS version 25 and means which were significant different were separated using least significant different. The results show that there was significant different (p<0.001) between all treatments combinations. Results recorded higher maize grain yields from100 kg N/ha + 5 t/ha cattle manure treatments for both seasons. High grain yield of 3.41± 0.042 t/ha was recorded from ZN 100 C 5 treatments during the second year and highest maize grain yield of 3.11 t/ha was recorded in first year. There was significant different (p<0.001) on the effects of combination of cattle manure and inorganic fertiliser alone on maize grain yields. Control treatments recorded lowest maize (1.17 ± 0.031 t/ha) and stover yields of 4.36 ± 0.046 t/ha. Results indicated significant different (p<0.001) on the effects of insitu rainwater harvesting, cattle manure and inorganic manure on maize stover yields. The use of integrated nutrient management and insitu rainwater harvesting has the capacity to increase maize yields and reduce food insecurity in dry regions of most sub-Saharan African countries.

Soil and landscape affecting technology transfer targeting subsistence farmers in central Tanzania

This article deals with technology transfer from science to agriculture with pearl millet (Pennisetum glaucum (L.)R.Br.) in central Tanzania as example. The major question is which validity recommendations from different types of field experiments have and how geo-information (i.e. soil and landscape position) can lead to more site-specific recommendations. Tied ridging and reduced amounts of placed fertilizer during sowing were tested to increase yields on researcher-managed plots on-station, demonstration plots in villages, and farmer-managed plots on-farm. While on-station trials provided potential yield effects, physical distance to the station and differing conditions led to a higher informational value of village plots that mirror the context of local farmers. The treatments often resulted in significant yield increase. Soil and relief information and distance to settlements (i.e. gradient of management intensity) are key factors for data variability in on-farm trials. Unexplained variability is introduced through leaving degrees of freedom with respect to management to the farmer. Apart from soil and physiographic information, the latter should be part of a detailed data collection procedure in agronomic trials in large numbers addressing Sub-Saharan smallholder farming. Balanced data sets with dispersed trials on crucial soil and relief units are essential for future research.

Rainwater harvesting and Leucaena leucocephala biomass rates effects on soil moisture, water use efficiency and Sorghum bicolor [(L.) Moench] productivity in a semi‐arid area in Zimbabwe

BACKGROUND: Sorghum is one of the major staple crops in Sub Saharan Africa but its production is mainly limited by moisture stress, frequent droughts and soil infertility, especially in the smallholder farming systems. This raises the need to develop climate smart options to improve sorghum production. The objective was to assess the effects of rainwater harvesting and use of different Leucaena leucocephala biomass rates on soil moisture content, rainwater use efficiency, and stover and grain yields in two sorghum varieties (Macia and SV1). The experiment was laid as a randomized complete block design in split-split plot arrangement from 2017/2018 to 2019/2020 season. RESULTS:The results show that tied contour (TC) and infiltration pits (IPs) significantly (P < 0.05) increased soil moisture content than standard contour (SC). Soil moisture content increased gradually with the increase in soil depth (20-40 cm > 0-20 cm), with 2018/2019 season having the maximum soil moisture content. Soil moisture content also increased with the increase in application rates of Leucaena biomass. Grain and stover yields were significantly (P < 0.05) increased by all Leucaena biomass application rates with higher yield observed in 2018/2019 season. SC had significantly lower grain and stover yields at all Leucaena biomass application rates. TC and IPs had comparable rainwater use efficiency compared to SC. Rainwater use efficiency increased with application rates of Leucaena biomass across all seasons and varieties. CONCLUSION: TC and IPs are better adaptive mechanisms against drought spells in semi-arid areas and can be combined with 10 t ha −1 of Leucaena biomass due to better yield increments realized.
