Irrigation water use efficiency in Maize production


Improving maize production in Malawi is critical to solving National food security concerns. One method of boosting maize production is to increase production of irrigated maize during Malawi's long dry season. The goal of this project was to identify best-bet management and N fertilizer rate combinations for irrigated maize production on smallholder farms.

In this project, we evaluate the response of maize to 3 different levels of N fertilizer and 3 different irrigation regimes. Different irrigation regimes--farmers practice, stage based, and water budget--were established at Kasinthula Research Station. In each irrigation regime, 3 subplots were established which received 100 kg N/ha, 125 kg N/ha and 150 kg N/ha. Data collection will start 3 weeks after planting and continue at a 3 weeks intervals until physiology maturity.


The One Protocol (Phi2, PSI, NPQ) II

The One Protocol to rule them all! Phi2, PSI, NPQt, combined!

Changes from previous The One protocol: - no longer outputs signal from the far red period, which simplifies the signal output for the user - changed distance between measuring pulses from 10,000 to 2,000 which improves measurement resolution - has an initial stabilization peri...

Chlorophyll content (SPAD) III

REQUIREMENTS: Firmware v0.41 or higher. Measures transmission at 940nm and 650nm in order to determine the 'greenness' of a leaf, an indicator of chlorophyll content and nitrogen content. The 940 is used to account for leaf thickness. Improvements over Chlorophyll content (SPAD): - performs 3 different spads at 3 intensities for thin and thick ...
