GROWTH AND YIELD OF HIGH PROTEIN CORN (Zea mays L.) AS INFLUENCED BY PLANT SPACING AND NPK LEVELS

In crop production, major production variables that a producer can manipulate to influence the production of a given crop are agronomic practices, fertilizer levels and plant spacing require special attention in the changing climatic condition. This study aimed to establish appropriate plant spacing and NPK levels. The following treatments were used: plant spacing (P1 70 cm x 20 cm; P2 60 cm x 25 cm; P3 60 cm x 20 cm)...

Physiological characterization of NADP-malic enzyme activity under 2,4-D toxicity in an aquatic fern, Azolla pinnata R.Br.

This work proposes NADP-ME activity as bio-indices for herbicidal sensitivity in Azolla pinnata R.Br. under 2,4-D toxicity. Azolla fronds were illuminated under saturated photosynthetic flux and bicarbonate induction. There was significant variation in the NADP-ME activity under light and dark conditions. This increased more when varying concentrations of 2,4-D were used for the up regulation of enzyme activity especially...

Effects of different rates of organic and in-organic fertiliser combinations on growth and yield of cuccumber (Cuccumis sativus L)

Organic manures are becoming important in the smallholder sector because of their ability to maintain ecosystem health and cheaply replenish nutrients that are lost due to soil erosion, leaching and crop removal. A field experiment was conducted in Mjinga communal area in Hurungwe District of Zimbabwe between July and October 2015, under irrigation to investigate the effects of organic manure application rates on the...

Introgression of adult plant resistance genes and marker assisted selection for leaf rust resistance in an F2 population of Kana, a released wheat (Triticum aestivum L.) cultivar in Zimbabwe

The incorporation of rust resistance genes into wheat cultivars is the most economic and effective approach of controlling rusts. The objective of this research was to incorporate adult plant resistance genes 'Lr34 and Lr68' into the rust susceptible commercial cultivar Kana+Sr2, Lr46'. Cultivar Parula+Sr2, Lr34' Lr46, Lr68' was used as the donor parent. Sequence tagged site markers, namely csLV34 and csGS were used to...

Screening sorghum (Sorghum bicolor L. (Moench) genotypes for resistance to covered kernel smut disease under artificial field inoculation

Covered kernel smut, caused by Sporisorium sorghi is a major threat to sorghum (S. bicolor L. (Moench) production globally resulting in yield losses as high as 75% on susceptible sorghum in Zimbabwe. Twelve sorghum genotypes were screened to determine the incidence and severity of covered kernel smut under field conditions during the 2014/15 growing season. In addition, the trial was done under artificial field inoculation...

Evaluation of early drought tolerant maize genotypes under low nitrogen conditions

One way to improve maize yields in drought prone small holder farming areas, where soils are mostly sandy with low organic matter and low cation exchange capacity is through breeding for drought tolerance and high nitrogen use efficiency. Low N tolerant cultivars have enhanced uptake capacity for nitrogen or have more efficient use of absorbed N in grain production hence are superior in the utilization of available N. An...

Genetic diversity assessment of wheat (Triticum aestivum L.) genotypes using SSR markers and morpho-agronomic traits

A narrow genetic base may lead to genetic vulnerability against biotic and abiotic stresses. In order to assess the level of diversity among 28 bread wheat genotypes, characterization was done using 21 Simple sequence repeat (SSR) markers alongside 27 morpho-agronomic traits. Based on morpho-agronomic data, the genotypes were grouped into three clusters. The first three principal components explained 23.92, 14.92 and...

Principal component analysis: A tool for multivariate analysis of genetic variability

A variable is a factor, quantity, character or symbol with values, which vary in contrast to a constant value that is fixed. Genetic variability refers to the differences inherent in the genomes of organisms. Multivariate analysis is a set of techniques dedicated to the analysis of data sets with more than one response variable. It involves a mathematical procedure, which transforms a number of correlated variables into...
