Description/Abstract

Genetic parameters for birth weight (BW), weaning weight (WW), pre-weaning average daily gain (ADG1), 18-months weight (18 MW) and post-weaning average daily gain (ADG2) were estimated using single-trait and multi-trait analyses. Data consisted of 2257 records for the Botswana Composite and 5923 records for the Tswana collected between the period of 1988 and 2006. The individual animal model (AM) and animal maternal model (AMM) were fitted in both analyses.

Description/Abstract

Cotton (Gossypium hirsutum L.) is an important cash crop for small-scale farmers in Mozambique. The yield is dependent on various factors of plant management, and this can be affected by variations in plant density. In Mozambique the cotton crop is mainly growed in plant and row space arrangement corresponding to 50,000 plants per hectare, which is considered low resulting in low cotton yielding.The goal of this study, was to evaluate the effect of plant density in cotton yield, Gossypium hirsutum L. The experiment was conducted in Namialo village, in a randomized complete block design with four replications in a split-plot, where the main plot was distance between the plants within the rows (15, 20, 25, 30 cm) and distance between the rows (50, 75, 100 cm) as subplots randomized in each plot, making plant from 33000 to 133000 plants per hectare. Results of this experiment showed no significant interaction between the distance between the rows and plants on cotton yield, number of bolls per plant and plant height. In addition, as the distance between the plants increased, the number of bolls per plant also increased. This experiment empathize that the combination of 70 cm between the rows and 20 cm between the plants, with a total density of about 71400 plants per hectare resulted in a highest yield.

Description/Abstract

Pigeon pea is one of the important legumes for export and domestic consumption in Mozambique. The objective was to evaluate the performance of the genotypes and to stratify environments for agricultural zoning and subsequent recommendation. The experiments were conducted in the northern region of Mozambique, to evaluate grain yield, in randomized blocks, with three replications and 20 long-maturing genotypes, in the 2016/2017 season in four environments. The results were obtained through the joint analysis and the complementarity of information from the biometric methodologies of Eberhart and Russell, Centroid and GGE-biplot aiming at better use of the significant GXE interaction. A mega-environment (Nampula and Namapa) was observed, of which Namapa district was the most discriminating and representative. The genotypes suggested for a recommendation as cultivars showed average performance. The ICEAP01490 genotype was of specific adaptability to favorable environments (Nametil and Namapa district) and high stability, is recommended for medium to high technology environments and the ICEAP01498 genotype was of specific adaptability to unfavorable environments (Nampula and Montepuez district), is recommended for low technology environments. The ICEAP01409 genotype can be indicated for a general recommendation. The ideal genotype with high mean, general adaptability and high stability was not observed, suggesting evaluations in more environments.

Description/Abstract

In the last two decades, Mozambique’s plantation forestry has witnessed several twists, which were driven by domestic and global changes. However, empirical evidence on the governance issues that account for a bleak plantation forestry future in Mozambique are lacking. This paper explores the governance issues that militate for the rise and fall in plantation forestry in northern Mozambique. We conducted an online email, face-to-face or phone call interview with 20 forest experts deeply informed about a decade and a half of plantation development in northern Mozambique, using 2005 as the baseline year. We then proceed with an explorative case study of two operational companies in the Niassa province: The Florestas do Niassa (now, build it) and Green Resources. We found strong evidence of a decline in the forest sector in northern Mozambique, linked to the following governance issues: (i) lack of flexibility, clarity and delay on the part of Mozambican Government to issue the land title (DUAT’s); (ii) Increase in forest fires, perpetrated by local communities who provided land for the plantations companies, but were dissatisfied with the unfair distribution of the benefits from afforestation projects; (iii) Poor infrastructures, especially road accessibility; (iv) lack of skilled labour as well as (v) political instability. Furthermore, the research illustrates how difficult it is to invest in forest plantations in Mozambique, despite its high potential and natural competitive advantages for the establishment of commercial plantations.

Description/Abstract

The Government of Mozambique will invest around US$50 million in agricultural research over the next three years. This feat was announced by His Excellency Filipe Jacinto Nyusi, President of the Republic of Mozambique in his opening speech of the First Agricultural Research Symposium held in KaTembe, Municipality of Maputo, from 31 August to 1 September 2022. The investment aims to stimulate and improve agricultural research in Mozambique through the improvement and operation of research and vaccine production laboratories, reinforcement of the multiplication of pre-basic and basic seeds, support in the operationalization of the Rice Research and Leadership Center and impact assessments of agricultural production.
